摘要：The invention relates to a spring carrier for the chassis of a motor vehicle. Said carrier is used to support a coil spring (1) which is braced between two spring plates (2, 3). At least one of said spring plates (2) can be axially adjusted by means of a drive unit comprising a gearbox and an electric motor. Preferably, at least one part of the piston rod (6) and/or the shock-absorber tube (5) of a shock-absorber or a suspension strut is arranged inside the coil spring (1). The aim of the invention is to develop one such spring carrier in such a way that the distance between the upper spring end and the vehicle body can be kept small in a cost-effective manner. To this end, the electric motor is embodied in the form of a ring motor having an external stator (15) and an internal rotor (16) which comprises a displacement nut on its inner side, said displacement nut axially displacing a spring plate carrier (21) connected to the spring plate (2) and externally embodied as a threaded spindle.
