Hello friends, please check out brilliant.org/LearnEngineering and learn about more fascinating mechanisms similar to steering. Personally speaking, I have learned a lot from their website.
It’s amazing the amount of engineering it goes to things we use everyday and take for granted. And also, these visual learnings are effective rather than just reading about it👌🏽
Absolutely until you suddenly experience total failure! Electronic steering depends on vulnerable processors, wiring and connectors and any problems within these components render the steering useless, you can't beat hydraulic power assisted steering , just had a total failure on Opel Astra .......and steering wheel was extremely hard to turn, any woman driver would have just given up.
I bet they got to that part of the video, realized their mistake in the choice of human model but decided that they don't have the time to fix the whole thing lmao
I would like to thanks the channel for providing such high quality material for free. As a mechanical engineering student, I have benefited a lot from all of the contents of the channel and sure learned a lot. Thank you, sir!
I hear so many times about people having issues with using a clutch, i never understood he difficulty of it. In my first driving lesson 10 years ago i drove away without talking about it, 2 years later the same at motorcycle lessons. I guess you just got to know what a clutch actually does mechanically.
Wow, I never knew that the 2 wheels are steered ar different angles! This video is an eye opener! And the power steering mechanism is quite clever. Infact all mechanics are work of clever men. Great animation. Thanks and keep it up.
And here I used to think a car needed alignment whenever I noticed a parked car with the wheels turned and the wheels weren't exactly turned equally hahaha! I Dunning-Krugered myself.
Lol I am Mechanical Engineer with a Masters in Aerospace Engineering, yet it never ceases to amaze me at the ingenuity and simplicity of these designs we use on a daily basis :) Engineering is so much fun!
just finished my first semester of mechanical engineering. experienced pure joy after predicting the planetary gear at 6:03. 😂 Great video, thanks a bunch!
If the planetary gear is used as shown the steering wheel has no authority over the direction of the car. If the wheel is held straight and the worm gear turns, the car will turn in that direction. I think there must be something missing.
In only your 1st semester?? I didn’t go over gears/dynamics until my sophomore year. 1st semester MIGHT cover free body diagrams in say, statics, but congrats if you knew gears that early on
@@crippletron6879 to be fair, we had like a semester on gears and it never came up again (except in projects).. it kind of got more and more theoretical later on with fluid- and thermodynamics... Buuut I'm going to have my bachelor's degree in half a year, fun to look back at this comment
Need to rewatch this a few more times to be able to simply and comfortably explain it to someone else in a way they'll be able to understand. Great content! Thank you
Thank you for the video! My mother recently had a wheel-alignment service on her car. It's interesting to know how this works, and see it in action. I didn't know the wheels turned at different angles - the ingenuity behind this is mind-boggling!
is it just me who observed what happend within 5 seconds after 4:51. How neatly this animator covered up the portion. He should make animated movies as an occupation apart from teaching.
@@adamaj74 I know what countersteering is, but it is hard to explain it in words. The fantastic animations that this channel produces will provide a much clearer explanation! Let me know if you want me to explain, I'll try my best.
I would have loved to see how they solved these problems when designing the power steering assist-motor, but also the countermeasure planetary gear set. Fascinating. My only regret is that we were unable to record the thought-processes of the geniuses behind this contraption.
The animation really helps a lot!!! This is better than school! School is nothing but a prison where we are force fed information that will be useless.. and we forget most of it!!
I understand absolutely nothing at college but here I get to learn so many things which are not even taught in my college, my concepts are clear and my knowledge is boosted. Syllabus in my college is 20 years old but bcs of learn engineering I get to learn latest technologies. P.S - I am a mechanical engineering student.
*Awesome Video... Details Explained. The Best thing of this channel is it's Animation. One can easily understand through Animation. Thank You Sir...for Great Work.*
6:28 - That's a really clever design. Not just for the failsafe reason. But also, when the motor has failed, the steering wheel is essentially geared down, so that the driver is able to apply more torque.
I started with curiosity about how IC engine works and now this has become an obsession. It's so complicated yet so practical to the extent it blows your mind. I can't imagine how much time it took to come with this ingenious idea. If this is complicated, then just wait till you see how the Speed gears of your car works and add on the clutch system.
I like how they chose to explain power steering involved one of the least common types. Most cars, including new builds, still use hydraulic power steering. That operates differently than the video example, and I think is worth diagramming for a more complete explanation of the mechanics of steering.
Lol I was thinking the same thing. Most people don't own cars with electronic power steering. I work in parts and I sell power steering pumps daily but have never an steering motors.
@@aimilios439 i drive one with no power steering as well, but I’m gonna say in my experience it was pretty easy, it’s not like you have to grip it really hard or smth. It’s rather a loss in controllability, especially felt on higher speeds. Driving on speeds like 80+ km/h gets a little bit scary even haha, especially if the road isn’t perfect. Maybe that’s the time you have to grip it harder but it’s still not that muscle-tiring
Steering without electronically assisted power steering activated as shown is steering against the friction coupling. I moved one of those once, not too easy. Great illustration!
I'm not a practicing mechanical engineer but I do enjoy the videos in this channel because it shows me new technologies that we did not touch in engineering school. However, the end of this one does not make sense. First of all, you can possibly back drive a worm gear. More importantly, when the motor drives the ring gear in the driver's intended direction, the planetary gears would drive the sun gear in the opposite direction. This further resist rather than assist the driver's steering effort
@5:40 You can most definitely back-drive a worm screw, if the worm angle is above the inverse tan of the frictional co-efficient. If the assembly vibrates, then it's even easier to back-drive. Great video, though!
@chocobonita I work with industrial machinery and farm equipment, and have some hands on experience with worm drive gearboxes. I've dealt with some machines unexpectedly back-driving their worm gearboxes, and that motivated me to learn the engineering behind how they work.
Insane how over the years of human evolution we've come to the point where we understand such things. Imagine the trial & error of trying to mechanically figure out how to make the modern vehicle of today. What's ever more mindblowing is that machines do most of the work in making them as well. Think about what the future holds. Crazy.
An excellent video but just a minor correction. At 5:45 the statement that a worm gear can't drive a worm is false. A very common misconception. When the worm can't be driven by the worm gear, this is called self-locking. In many designs, this is a requirement. But it is inefficient. So for applications where efficiency is important and self-locking is not required, then the worm and worm gear set is not self-locking. It's all about the application. Interestingly, this leads me to wonder why self-locking would be deliberately used in power steering. I imagine the use of a high-efficiency worm gear set would actually be better in power steering. In the case of electrical failure, then back driving the BLDC motor would not be an issue. Just a thought.
Thanks for posting that correction. I wasn't previously aware that you could have non-self locking worm and worm gear sets. I'll admit that I'm guessing here but wouldn't the advantage of this set up be that, in the event of failure, you obtain the benefit of a gear reduction between the sun gear and planetary gears. That is to say, you'd need more turns (of the steering wheel) lock-to-lock but less torque input from the driver.
@@steplusplus I watched it again and I get it now. (was probably drinking first time LOL) The locked ring gear forces the steering wheel torque to be transmitted to the rack and pinion. If the worm drive was not self-locking the steering wheel torque would backdrive the power steering motor and not drive the rack and pinion. Thanks for your suggestion.
@@robguyatt9602 Yes. And, if there was no planetary gear set, the torque would indeed drive the steering, but would simultaneously backdrive the bldc motor, which would provide extra resistance due to the high gear ratio from the worm and eddy currents.
When I see these videos explaining these good old mechanisms, I am astounded at the genius of the engineers who invented varieties of gears and pinions, differential gears, hydraulics , and pneumatics for transfer of motion and torque. I think that mechanical engineering is the true engineering. World can’t without it, notwithstanding the huge number of specialisations which have developed during the last thirty years.
Wow man loved animation and level of explanation like asking questions why ..then telling because this is problem if we do this and after telling "so solution to problem is"..man u r not just giving information ..rather u r improving approach of engineering ... truly name of u r channel matches u r work 😍😍😍 ty for u r efforts
Thank you for this! This helped me understand electric steering much better, i feel way more confident going in for my final at my college tomorrow for first year mechanics
What is obvious from this video is just how ingenious and superior hydraulic power steering is over electrical. The mechanical advantage is built into the design rather than relying on electrical components that can fail.
The trick is in the angle of the linkage at the neutral position (3:12). If they were starting at 45 degrees and in line with the rack and pinion, both wheels would move the same angular distance and you would need new tires very quickly. Instead, they are neutral at ~20 degrees and the rack and pinion is to the rear. The rack moves the same distance on both sides, but because of the initial angle of the linkage the wheel turns farther when turning away from the center of the car.
@@pyrobeav2005 With the wheel straight ahead, draw a line between the steering arm pivot and its connection with the tie rod and continue until it reaches the rear axle. Wheels will toe out the correct amount on turns when this line intersects the rear axle at its Left Right center. Toe out on turns is not adjustable and some alignment techs interpret this to mean if it's off nothing can be done. Some go step further and don't check it. Reality is if the measurement is off the car has bent parts
Wow this is by far the most informative video about EPS.. Thank you for the effort to do the video! But there is one thing you should also explain in the video, that is how the tie rod + rack & pinion + steering arm mechanism turning the wheels at different angle and always achieve the common point.. Does anybody know how this happens? Thanks a lot!
Hey God bless those people who have created this channel . Truly speaking, too much knowledge is there on this channel . And one more thing to point out you show things in such an interesting manner that even the most difficult concepts slip into the mind like butter. I really don't have words to thank you but just one thing We salute you Thank you
The ratio at which the wheels turn compared to the steering wheel when assisted by power steering differs from the one when power steering is inactive (car shut off) since the ring gear doesn't turn in latter case, thus giving the gear box a different gear ratio. This would mean that if I were to turn the wheels all the way to one side when the car is off and then turn the wheels back after starting the car, the steering wheel would be in a different position than before, right? Or does the power steering account for the different gear ratio?
I think issues like this is considered by designers already so different position won't happen. And as I know the steering locks up when the car engine is off so idk how are you gonna turn the wheels like that.
But what isn't explained is how the rack-and-pinion steering mechanism achieves the different angles on each of the steering wheels. As in the components on each side are mirror images so the difference in the angle must come from something else, maybe the initial shape of a single component, but what component is that? Or I must have missed something?
@@cintowin That’s similar to someone saying walking is easy and then going to smartass that walking backwards on your hands is difficult…. Normal steering straight forward is the most simple thing in a car.
@@Engineer9736 you must not live on back roads or ever had alignment problems- because yes, these are common occurrences. I've seen many people who can't even swerve a pothole. It's about knowing the perimeter of the vehicle your driving which all equals ....what? S t e e r i n g. Because these are all parts of steering. Unless your talking about sitting in a parking lot with your car in accessory mode pretending to steer. Then yes you have a point. Good job.
Hard question: What happens when the motor fails detecting drive wheel movement? Will it keep supporting turning in one direction while the driver is trying to turn other direction? How do they prevent that?
Of course it won’t keep turning into one direction. But if you want to know the indepth details then you’ll have to reverse engineer the whole mechanism.. it will also be manufacturer specific on how it’s exactly done. It will involve sensors and electronics and software.
Wow i didn't know they used planetary gearsets like in automatic trans's in a electric power steering motor. Can you do the insides of a Hydraulic power steering? :D
It was very clear and as the video continued your answered every questions that I asked myself such as "wait, in case of motor failure the wheels are jammed" :D Thank you for the awesome content!

Hydraulic power steering also makes steering effortless. It has been around longer than the electric systems that are becoming more common.
Electric is more popular now because there is no parasitic drag on the engine and the system is lighter. This makes the car more fuel efficient.
this is just cool to watch....i appreciate engineering more each day.
Can you do a video on hydraulic power steering and other forms aside from electric?
Best explanation by far

As in the components on each side are mirror images so the difference in the angle must come from something else, maybe the initial shape of a single component, but what component is that? Or I must have missed something?
no u didnt miss
Because of the shape of the lever that conects to the wheel's axle, which has a specific angle.
It's called Ackermann steering geometry
Wow what an animated informing video
"when you learn to drive, the most difficult controll to master is that of steering" literally the most intuitive control there is on a car..
Well technically when you think about backing up and all the challenging aspects they all revolve around steering
@@cintowin That’s similar to someone saying walking is easy and then going to smartass that walking backwards on your hands is difficult…. Normal steering straight forward is the most simple thing in a car.
@@Engineer9736 you must not live on back roads or ever had alignment problems- because yes, these are common occurrences. I've seen many people who can't even swerve a pothole. It's about knowing the perimeter of the vehicle your driving which all equals ....what? S t e e r i n g. Because these are all parts of steering. Unless your talking about sitting in a parking lot with your car in accessory mode pretending to steer. Then yes you have a point. Good job.
What a beautiful working principle and a beautiful video!
Where the hell is hydro power steering? This is wack
And pitman aswell... lmao
In the past, lol
I actually want them to do a video on that also, just couldn't resist the joke.
its bad that's why
it was used in WW2 army jeeps
@@vampy625 has some disadvantages but it feels way better than electronic power steering
@@v0ldy54 it feels like someone's playing racing game with keyboard
This channel is awesome
Hard question:
What happens when the motor fails detecting drive wheel movement? Will it keep supporting turning in one direction while the driver is trying to turn other direction? How do they prevent that?
Of course it won’t keep turning into one direction. But if you want to know the indepth details then you’ll have to reverse engineer the whole mechanism.. it will also be manufacturer specific on how it’s exactly done. It will involve sensors and electronics and software.
4:50 Thank you for protecting her modesty.
The hardest thing I've learnt from my first driving was mastering cluth
Cluch
@@Non_Consistent_Potato *CLUTCH*
@@gaurav_bora_ oh, even I spelled it wrong XD I knew there was something wrong with it
i learned here more in 5 hours on this youtube channel than 4 years at school (Autotronik 4 years maturity-highschool diploma)
The mechanism looks symmetrical. Which part causes the turning angle to be different for each wheel?
Observe the idler arms with regard to their alignments to the rack.
Best video .... Royal Mechanical 🔧
Wow i didn't know they used planetary gearsets like in automatic trans's in a electric power steering motor. Can you do the insides of a Hydraulic power steering? :D
These videos are simply the best!
iam understand easily by your video thank you ...
This channel is less carefully animated and explained than most other channels I've seen that advertise for brilliant.org.
Ah, engineering videos. My escape after watching animals eat each other and spooky haunted house videos.
Thank u for making this visual learning.
Another awesome Video.
wow... brilliant... physics is always fun...
Damn I never knew how steering wheel system was complicated
Power steering is a god send
Sir,could you please explain about fuel cell technology.🙏🙏🙏🙂
Fuel cell technology is almost dead :(
No it isn't!!!
It was very clear and as the video continued your answered every questions that I asked myself such as "wait, in case of motor failure the wheels are jammed" :D
Thank you for the awesome content!
5:00 why so many buttons under the steering wheel 😅 Thank you for the explanation
this was really fascinating
Pls. Explain, WHY REAR WHEELS Doesn't Slip instead of having different speeds on a Turn
Adarsh Rathore, there is a differential connected in between the rear wheels which allows the rear wheels to rotate at different speeds. here's a video - ua-cam.com/video/yYAw79386WI/v-deo.html
One word For you Brother, Differential...
Differential gears
Or just a metal bar, with 2 wheel hubs mounted on so the wheels rotate freely (in fwd)
Learning something new every day thanks 2 this channel 🤓🤓
Hmm in 5:11 there is something not right with that steering wheel don't you think ? :D
Upside-down
LOL
😂😂😂 Mr. Bean mounted that steering wheel
Yeah, wheel is the most significant invention of mankind. It's used in most applications, wheel is the thing kept us moving through ages.
4:45 Why did you draw more skirt??? :) :) : )
