Control Arm Information

Wishbone moves the centre of the wheel in a plane that is perpendicular to the longitudinal axis of any vehicle, as it is located along the longitudinal axis. Wishbones have been always widely used in simple cars, often sports and racing cars. Wishbone is a rather complex type of car suspension. The springs are located longitudinally and vertically, while resting in the back end of the partition between the cabin and the engine compartment. Suspension arm moves the centre of the wheel in perpendicular and longitudinal axis of the plane. It is set along the longitudinal axis.

To ensure that efforts were transferred from the shock absorber, there is additional axial lever in vertical plane on each side. Its front end is fastened at the top rack. The rear one also has to be fixed on the panel. In the middle part there is a stop for the front end of the spring. There are two types of wishbones: single knob and double lever.

Wishbones of any car should be light, have a long-term resistance to transverse and longitudinal bending, as well as to the effects of lateral, starting and braking forces. There exist two main methods of production. The first one is by drawing sheet metal or metal strip. Wishbone may also be obtained by forging steel or hardening the ductile aluminium alloy.
