Okay guys, I think I figured out how this works. If you know cars, you know this is definitely not double wishbone, it’s just a trailing arm/swing arm. Not familiar with peugeot, but I believe this is a 206. The 206 used torsion bars and a shock that ran back and up towards the rear of the car. This guy took the torsion bars and shock out and just used the shock’s mounting point on the trailing arm to run a rod up to the rocker that controls the coilovers. Changed it to a cantilever setup for ease of tuning and adjustability he’d have. Pretty genius. Edit: the torsion bars still look like they’re in lol
I knew something was off. And a qick question, is a double wishbone with only torsionbars still a double wishbone? Imo it is because the spring doesn't usually tell what type of suspension a car has.
@@tunk_2ton168 alot of pickup trucks use double wishbone suspension in the front with torsionbars, but in this video it is just a trailing arm for the rear suspension
Yeah I have a Citroen that has similar suspension as the 206 but I still don't get it how he connected a rod from the swing arm to the rocker arm I mean they move in different directions. It must be so genius that I can't get it😂😂 Edit: ok I got it now I just checked where the shock mount is and how it compresses the shock. Basically when the wheel goes up, the mount "moves backwards" so it makes it possible for this setup to work at this angle
...there's another pivot point or joint, that allows this kind articulation in the suspension system, it's definitely not visible in this video... but I could be wrong 🤔 the video and the animation don't provide enough evidence of how this works.
Im an ASE Master Tech and auto instructor, and never having seen a Peugeot with this suspension im glad other posters were able to identify it so i could see what was actually changed. I think it's a pretty ingenious way to work within the space constraints. For a racecar it's probably not MUCH easier than just cutting/fabbing bodywork to make for a more conventional shock/coilover placement (probably tie into a cage also being built), but there are probably classing reasons not to do that. Creative use of a bellcrank and some empty space. Looks very easy to service/change springs, too. I like it.
this is a fix to work within class rules that prohibit changes in chassis (except roll cage obviously) allows use of coilovers where OE design uses torsion bars and improves damper ratio
This thing sounds absolutely amazing. I just don’t people that like nothing but V8s. This is music to the ears of true car lovers that enjoy all configurations.
@@dan1906 I missed a word. But it appears you may have trouble filling in the blanks with deductive reasoning. It was “get” if that helps you reach a conclusion.
@80PercentAshamedOfU You missed the point, which isn't surprising. With a pompous attitude you brought up a topic that wasn't even in discussion, just to rag on people you feel are beneath you. That's why I called you out. Sad that I have to spell it out. The shame is on you.
Dang I really like this, I wonder how it could be altered to leave room for half-shafts, it could be really good for rwd swaps, lot less cutting and messing with the strut towers, only finding drilling spots and welding supports (in the best situation).
Did someone ate the wish bones? Isn't it a horizontal cantilever suspension? Why the variable caster angle? Isn't the axle attached to a single swing arm? Nice for a lower center of gravity, not nice for all the stress on that swing arm axis.
I wanna see how that works. I wanna see the other side of that arm that's pushing the trailing arm/lower control arm down to lift the car. That'd be cool to mound bags sideways under a mini truck. Or even sideways in the bad
Buddy this is still the peugeot swing arm suspension you just changed the position of the spring it won't actually change anything. Double wishbone has 2 control arms connected to a knuckle with a coil spring over shock absorber attached to either the knuckle itself or the lower control arm going up and down in a straight line. This is a pushrod suspension setup on an old peugeot swing arm rear axle. It's not a double wishbone.
@@agoradacerto This is an aftermarket kit for the Peugeot suspension which keeps the original torsion bar spring and adds a coil on the relocated shock absorber.
please show how the verticle wheel motion is converted into horizontal motion in the damper. Its looks great, but I dont see the mechanism in the video.
@@bigpig187 "torsion bar" is also a spring. F1 still uses "horizontal springs". They used to be pushrod 10 years ago but now they changed to pull rod style geometry thats prob the only major difference compared to 10 years ago which they were still using torsion springs back then as well. They ditched coil springs a loong time ago but the point stands, torsion springs are also placed horizontally just like the coil springs in this video
A gas-charged shock work equally well in any orientation. It only needs to be vertical if it is a traditional twin-tube design with the outer volume as an unpressurized reservoir.
If you want to see a crazy suspension look up Maier racing in Hayward California. He has a 1965 Mustang with a rear suspension that you have to see to believe. It is an autocross winner over and over. The suspension is in the trunk.
@@terencehawkes3933 Correct - the suspension in the video is a single trailing arm per side, not double wishbone at all. Only the shock linkage (which doesn't change suspension geometry at all) is similar to what is in the animation.
Is this the rear suspension? Don't see a steering mech The wheel travels without bumps while simply accelerating - so that has to be load transfer to the rear susp right?
It's not - the original torsion bar is still in place. But a coil-over with a 1:1 wheel rate (it moves the same distance as the wheel) doesn't need to be very big.
@@GalaxyVette this will be more than adequate strength wise, especially for the rear axle of a lightweight FWD car, it doesn't experience huge forces. *Could* suffer with deflection under heavy lateral load but still wouldn't buckle. There are many factory setups with "skimpier" designs than this.
Would be nice to see the mechanics of this. If I'm not mistaken this was once a Peugeot/Citroen rear axle. So no Toyota in this video, despite your description. So a single trailing arm with a torsion bar as a spring, an anti-roll bar through the center connected to the other trailing arm and a shock absorber for each trailing arm. I don't really see the 'double wishbone' configuration here, rather a system of turning the vertical movement of the trailing arm into a horizontal movement in order to... create more adjustment ability? Classic double wishbone can be found and easily seen on cars like Caterham 7, Donkervoort and even F1 cars.
The miniclip is not the same setup as the video. Is not a double wishbone suspension, it has some twisted pivot suspesion on it. Look good to low the center of gravity but looks not adjustable.
this type of suspension is known as Push-Rod suspension found in high-end sport cars and F1s, it is quite uncomfortable on the streets, as it is meant for the track.
Now this can easily be integrated with AI based system that can read the 3D mad of the road just ahead and a motor with counter/compensating force can work the arm right in place of the spring(or along with it) so the the vehicle/chassis itself remain in the same position with respect to the road
Hope you aren't too attached to your wheels, hubs and brakes. They will soon leave the vehicle hi and dry. Aside From how easily this would be snapped completely from it's mounts I'm looking at the diameter of bearings asked to support such dynamic loads and know their service life is very short. Most children's toys have more robust components.
okay guys i think i figured out how this works. I, on the other hand, who do not speak English, did not understand how it works or the advantage. they are also of the opinion that the more joints there are, the greater the risk of breakage, especially in the off-road field. I apologize for the automatic translation
It is using almost all of suspension travel :/ its so close to bottoming out.. The idea is cool but I'd look for some stiffer springs and beefier struts.. But i also have no working knowledge on this type of setup.
@@AktuvnaFazaGenozudySlovjan он идёт от 150 до 200 примерно,учитывая где-то 6500-7500 оборотов на 4 передачи,подвеска отрабатывает очень хорошо,что и видно на видео. Мне не понятен момент передачи от скручивающего момента до сжатия аморта. Работает как торсион,а сжимает амортизатор, как? Вот где вопрос.

The trailing arm of the suspension has a shock mount extending down, near the pivot point. When the wheel goes up that point moves back, pushing the pushrod, which moves the crank, which pushes the shock and spring.
