Abstract

A coil spring (1) and support bearing (2) arrangement for suspension struts (3) with a shock absorber, supporting a steering knuckle of an automobile has a rolling-contact bearing (7), with an axis (x); a receiving body (6), arranged below the rolling-contact bearing (7) in which the rolling-contact bearing is inserted; and a coil spring (1). The coil spring (1) has a force application line (f), which is offset relative to the axis (x) of the rolling-contact bearing (7) at an angle (a). The coil spring (1) has a first portion (8), which, starting from the winding end (17), winds around the receiving body (6). The first portion (8) abuts the receiving body (6). The winding end (17) of the coil spring (1) is arranged in the area of the plane E1 formed by the force application line (f) and the axis (x). Thus, the axial forces acting from the coil spring (1) onto the rolling-contact bearing (7) have a maximum in the area of the force application line (f) of the transversal forces acting on the rolling-contact bearing (7).
