Control arm

Depending on customer requirements, components are adjusted to suit both comfortable and fast driving, in the process guaranteeing optimum safety even in extreme road conditions. Years of experience in the development and manufacture of control arms for every type of independent wheel suspension have made this possible.

Set up / Function

Control arms act as the link between steering knuckle and vehicle body in the case of independent wheel suspensions. Depending on their design, two-point and three-point, on rare occasions, four-point arms are available. According to their function in the vehicle, they are subdivided into guiding control arms and supporting control arms. All versions are connected to the steering knuckle mainly via ball joints. Rubber bushings are used in the great majority of cases for the connection with the body, frame or subframe. In line with the particular application involved, control arms are manufactured in welded steel or aluminum sheet or in cast iron or light alloy. Acting in conjunction with the tie rod, control arm design has a decisive effect on vehicle handling. Guiding control arms absorb braking force, motive force and radial force. Depending on the wheel suspension, car manufacturers fit them as upper or lower control arms on the front and rear axle. In addition to absorbing braking force, motive force and radial force, supporting control arms also support the vehicle weight. They are used in the lower section of double wishbone axles and multilink axles.
