ABSTRACT:
A support for a coil spring of a spring strut of a motor vehicle, which is cardanically disposed on the vehicle body, comprises a coil spring which, on one side, on the side of the vehicle body, is supported on an upper first elastic spring pocket and, on the other side, is supported by way of another lower second spring pocket which is stationarily held on the spring strut. In the operating direction of the coil spring, the upper spring pocket has areas of different elastic characteristics. In an area of high axial pressure forces of the compressed coil spring, the elastic characteristic of the spring pocket is less than in an opposite area of the spring pocket of lower axial pressure forces of the compressed coil spring. By means of this development of the spring pocket, a disadvantageous bulging of the coil spring during compression and rebounding movements is largely prevented.
