Formula-3 Racing Car


Greater differences than those between the wheel suspension of a street vehicle and those of a racing car, are hardly possible. Whereas the axle drive shafts still seem to be recognisable, the hydraulically controlled spring and shock absorber units with the complicated diversion system, are unusual. They are also called "push rods", meaning something like "bumpers". It means that the spring compression forces are transmitted through a slender push rod inwards. One also has to get used to the short spring travel. In formula 1 cars the spring and shock absorber units are even smaller. If they don't have hydraulic control, they are at least adjustable in the compression- and the rebound damping.

Unfortunately, from this position one can only see the upper double wishbones for the wheel guidance. Interesting here is, quite the opposite to the standard car, the huge amount of space needed. The more the front struts (in the direction of motion) are deflected forwards, the more impulsion and also braking forces can be taken on by them, and they can still be relatively favourably dimensioned. In formula 1 cars nowadays, even the tubing is aerodynamically formed.The above figure, by the way, shows a, compared with the formula 1, substantially smaller and lighter (approx. 350 kg) formula 3 vehicle. 06/09
