Abstract
A bearing for a spring strut as well as for a coil spring of the spring strut is provided by way of spring supports which rest against supporting elements and are held in a mutually non-rotatable manner by twist fixations. The spring elements are constructed such that the same stiffnesses are formed over the circumference of the spring winding even though the twist fixation is provided. Furthermore, a spring plate of the lower bearing of the spring is provided. The spring plate is adjustably arranged on the shock absorber tube, and thus springs which have different lengths can be used.
Claims17
A spring strut for a motor vehicle comprising:
- bearings for a coil spring with elastic spring supports received by supporting elements, locked in the supporting elements, and on which spring supports the coil spring is supported, and
- a spring supporting surface on at least one of the elastic spring supports which extends in a sloped manner corresponding to a pitch of the spring and having an elasticity which is the same in a supporting area of the spring,
- wherein free ends of the spring are supported by way of said elastic spring supports received by the supporting elements, one of the elastic spring supports being held in one of the supporting elements on the vehicle body and the other of the elastic supports being held in the other of the supporting elements at a shock absorber tube,
- wherein each of the supporting elements has a closed circular construction and engages with a corresponding one of said spring supports by way of a twist fixation,
- wherein each twist fixation comprises mutually spaced teeth which engage in an opposing recess in a corresponding one of the spring supports, and
- wherein a clearance formed between the teeth and the recess has lateral boundary surfaces on which the teeth rest in a form-locking manner.
