I'm surprised they went with cast links, it's a fairly simple part to machine for a significant strength improvement. And for such a small production castings usually cost more than machined parts, is it an OEM item?
@@omallykaboose Could be, but the design doesn't fit a printed part. They're usually hollow tube with internal ribbing to maximise the strength/weight ratio. They rarely feature material cutouts as this part has.
After today, the second car is also out after the nose dive. I wonder if it's the same issue. I also knew the problem of the weak washer from my own experience. I had the same issue on my homemade woodchiper. The knife went loose and airborne, almost killed me... Solution was no washer.
How many stages can a team miss? They could get machined replacements quickly for suspension problems. Bearing assembly may take longer. The casting failure is an amateurish mistake - simple failure testing (or selecting an appropriate manufacturer / engineer) would have solved this. Sad to see, because I like their design philosophy.
Surprised too. Cast pieces like that are extremely stiff. The only reason they work on oems cars is because they used soft bushings. Also they are meant to wear that one uniball on the control arm. If they used all super stiff bushings you’d want to whole A arm to flex, i.e chromoly a arms atvs and side by sides.
I know this isn't the video for this topic but i wanted to ask, why do most of the dakar cars not have rear wings and front dive planes and splitters? There's almost no aero work on the cars besides minimizing drag and getting efficient cooling but no downforce generating devices like on rally cars.
I really enjoy your video can you please make a video about the difference between categories in dakar t1 and t2 ,t3,t4 what are the specification.....
Sounds like some pretty poor engineering went into that front suspension, the first rule of designing a competition car is to use the best materials and processes available. Cast suspension parts are way down the best list.
2025... Forged spares... But also remember that team astara is also running a CR7 and it looks like they're doing well... Maybe driver input has something to do with it... Is astara running audi engines on the bio fuel? Great video
The subject is interesting as engineers find it difficult to simulate dynamic shock. However, of all events the Dakar really does seem to be completely pointless and manufacturers would be better advised to think of the real priorities: technical advances to reduce CO2, fuel and tyre particulate emissions. WRC, WEC and F1 are on the right track, although flying the teams around the World is increasingly looking stupid.
Dont watch it then. I dont think f1 is going the right way not with hybrid, porsche and audi synthetic fuels might be a better out come. End of the day battery manufacture os really bad for co2
@@Andrew-vx2ls exactly and will only get better. What i dont understand is that you can make low grade diesel from plastic bottles. Wouldnt that be an avenue to explorer would also get rid of the plastic recycling problems. Would be ideal for the trucking and heavy plant industries
To be honest I'm surprised that, they run out of spare parts. I mean 3d printers, even industrial grade ones are accessible as never before and I bet you can quickly redesign them with a different topological optimization, which suit the task better.
Even with metal 3d printing you still need to go through post heat treatment and machining operations it is not as simple as just send a part to a printer and then installing it
You would have to metal sinter such parts and such a machine is nothing you take to the Dakar. 3d printing plastic parts won’t solve the suspension link issue.

Thats what I thought too.
could be SLS metal and not cast and the translation is just bad

They are machined links the heat treatment was incorrect
CNC gives worse internal grain structure then cast or forged parts which might be why they chose it and it's also a cheaper manufacturing process.
Very interesting; you won't get these insights anywhere else on yt. Thank you again.
Very welcome
Very insightful, as always!
Glad you enjoyed it

if you miss one you don't get to go to the next location at all
Thanks to be so passionate and for putting so much effort
To share it out”
My pleasure!
This is great information - thank you!
Great video, thank you. Can you make a video about how they removed all ball joints from the suspension and used two sealed bearings instead?
Bro u just good at what u do.
Great analysis and information 👏🏻
Wonderfully detailed analysis

3-D printed parts? MIM?

grip at speed isnt really an issues. and with the ground clearance they need, ground effects /splitters are not useful.

Never understood why they are built so delicate and then cast parts! These designers need to go hang out with some baja guys

astara is running a cr6-t
@@rkxbox6433 but the back end looks like the CR7... It's confusing with the front that looks the same
@@Koup_TV_ side profile is the best way to tell imo
The Astaras have a modified CR6T bodywork but run the 7l V8 and rear wheel drive
@@bsport320 thanks, will you do a video on the astara?
Kinda ironic isn't it...

Could you pkease do series vedios on ssv category as well.
