If the black thing is the wheel, the light grey the dumper, the darker grey thing holds the wheel and moves with it up/down around the dumper when expirencing bumps, and the blue thing is hydraulic device that alters the angle of the dumper and by doing do it alters the camber of the wheel.

If you put a sensor in each corner of the car, which measures the distance of the car to the ground and tells the hydraulics to alter the camber you´ll have perfect camber controll

Would this thing actually work?

This is a "sliding pillar" suspension which uses a damper, spring and a vertical casting that the D & S attached to. Your design has the added feature of camber change with a hydraulic cylinder or a rod.

Well not so good

I was thinking because of the limited space in my hybrid project I could use something more space efficient than the double whishbone suspension

The idea coulb be good : but how about the stabilizer bar? (not sure of the english word). And how about the spring? A suspension is composed of springs AND damper. In F1 you do not see the springs because they are build like torsion bar (like rear suspension on european small cars)

With this system : each wheel is independant. This is good on bumps but not on turning.
And how about the steering strut? When your wheel is moving up, your wheel will rotate.

If you have a thermic view of it : you can suppose that your suspension will be too fast on braking. The brake will make the oil of the damper too hot and too fluid.

If you have a dynamic view : you make the weight too far from the gravity center. And this weight will move. So the suspension will not be so sensitive, and the maniability of the car will be bad.

on an road, competitin car-->not so brilliant

For half baked ideas such as this one, a great site is halfbakery.com.

Experts and non-experts alike debate the plausability of your idea, or tell you if it is already thought of. The discussions on motors are quite amusing.

Here is a link to one of my ideas.

new picture including the anti roll bar (stabilizer bar) yellow, steering column light blue, and a spring red.

thanks for the link

I used a non-independent front suspension design on one of my electric cars and it was that, that I put possibly one of the biggest embarrassments in my life down to.

I was just pulling out on to the track and when I hit a bump in the road which sent a jolt down the steering causing the steering wheel to turn left sending the car in to quite a wiggle and lead me to crash into a marshal.

Now what ingredient could I be missing out on because surely this would happen to every kind of front suspension??

This is known as a sliding pillar suspension. Morgan used to use on their road cars and trikes. With the right sliding bearings the system works, but camber will alter with body roll, in some respects its similar to a beam axle, but without the single wheel bump problem. Of course the other issue is creating the supports to manage the loads from the suspension, this could end up being thicker than two wishbones and a push rod. But on the plus side they are static which may aid aerodynamics.

the idea is good , but how are u going to control the camber , ? have u thought about the tyre wear , and other handling problems that could happen , idea is cool, this could bring stability in cornering with respect to the speed .

Yes Carlos, I´ve allready seen it but one thing I don´t get - is there any camber altering device integrated?

To mahesh248 and scarbs: I´m aware of the camber problem during leaning, that´s why I have the hydraulic cylinder (blue on the picture) to change the camber during leaning

Good idea, I remember a Peugeot concept car, 3 or 4 years ago, with 3 wheels (2 at front, 1 at rear) that had the capacity to control electronically the chasis.

Does hydraulics have enough speed for that aplication (racing)?

Camber control might be built into the hydraulic steering?

Imaginative and wierd ...but have you looked at a "tilt wheel" front end or single sided swing arm; "steering in hub"? These ideas come from different concept cars and motorcycle design.

I remember in another thread we discussed using a backbone chassis which provides lots of room for almost any suspension system. Even a monocoque does. Why do you feel you have space limitations?
