Wishbones are a component of automobile suspension. Wishbones are installed across the car perpendicular to the direction of travel and connect the wheel mount either with the axle (eg: multi-link rear suspension) or directly to the body (eg: MacPherson independent suspension). At each end they have in each case at least one connection supported on bearings (ball joint and/or rubber-metal composite bearing) and thus allow for the vertical movement of the suspension.
The function of the wishbone is mainly to take up horizontal forces, such as occur when accelerating or braking and cornering.
Triangular wishbones are used in most SEAT models for the front wheel suspension and form a second, lower bearing of the vertical axis about which the steering movements are performed.
