Abstract

A spring element includes a longitudinal axis, a main body that extends along the longitudinal axis and which can be elastically deformed between an uncompressed base state and a state in which the main body is compressed in the direction of the longitudinal axis, a groove extending peripherally on the outside of the main body, and a supporting ring arranged in the groove. A plurality of cut-outs is formed between the supporting ring and the main body in the groove in the base state of the main body. A vehicle shock absorber and a vehicle can use the spring element.

First claim

The invention claimed is:

1. A spring element for a vehicle shock absorber, comprising:
a longitudinal axis and a base body which extends along the longitudinal axis and can be elastically deformed between an uncompressed basic state and a state in which it is compressed in a direction of the longitudinal axis;
a groove which runs around an outside of the base body; and
a supporting ring arranged in the groove,
wherein in a basic state of the base body one or more cutouts are formed between the supporting ring and the base body in the groove,
wherein a gap which permits air to escape is formed between the supporting ring and the one or more cutouts.

2. The spring element according to claim 1 ,
wherein the plurality of cutouts are embodied in a form of:
cylindrical, partially cylindrical or hollow-cylindrical recesses,
conically tapering recesses,
partially conically shaped recesses,
polygonal or partially polyhedron-shaped recesses, or
a combination of a plurality of the recess shapes.

3. The spring element according to claim 1 ,
wherein the plurality of cutouts are provided and are arranged distributed uniformly over the circumference of the groove.

4. The spring element according to claim 1 ,
wherein the base body is partially or completely composed of an elastomer.

5. The spring element according to claim 1 ,
wherein the supporting ring is partially composed of an elastomer, and has a metal core, which is encased by the elastomer.

6. A vehicle shock absorber comprising:
the spring element according to claim 1 .
