How cool is this? In-wheels suspension

[19,69camaro]

I was killing time last night on youtube and came across this...

and some more information for you suspension junkies http://www.multimatic.com/products_t...gy/index.shtml

Is it just me or does it look like they could have a serious bumpsteer problem?

[Bigblue73]

I don't think so since all the motion is a single plane. Everything is linear to the wheel so technically the wheel does no go through any type of arc.

so much wrong with that car. Yes, it will bumpsteer.

I took a look at it a little longer and realized that the steering arm is fixed on the chassis side so there will be no movement on bump

Maybe I just don't understand the technology but to me it is a very cool car and I would love to have one

I just like his hair do.

I agree Donny.

I must be missing something. These are smart guys doing really cool stuff and I am sure they covered the bumpsteer thing but I just don't see how it can work. If the spindle slides up and down on what looks to be the king pin inclination and the tie rods that are already pointed upward a bunch, I would think it would toe in a whole lot on compression. In the video they were driving on a pretty smooth road so it is hard to see if it moves at all.

Negative camber gain is a good thing and it seems this would go positive on the outside tire.

All that aside, the car is still ugly.

That's where I was going, plus bumpsteer and travel. Might be good for a street rod, but that's all I'm seeing?

The steering arm on the spindle is fixed, the steering rack is fixed I see no way for it to bump steer. God that is way more tech then I would want to have to buy or repair though. The exposed spring /valving is really cool though.

no bumpsteer, since the steering arm doesn't move..

the part that i liked was the way they use hydraulic cylinders at the wheels that are hooked to other hydraulic cylinders with springs mounted to them to control the wheel travel- you could mount them anywhere in the car, including right next to the driver so he could individually adjust the preload on the springs on the fly...

yes, plus it sits between the pivoting arms.

It's cool and all but I thought camber change of a dual A-arm system improved grip? It's a cool idea and I like the way it looks but I remember when only crappy RC cars had that kind of suspension and the goods ones had arms and coil overs.
