Abstract

A spring strut bearing with a cap and with a guide ring which is mounted in a rotatable manner relative to the cap about a rotational axis (D), an axial bearing being arranged between the cap and the guide ring. The cap has a seal, and the cap is connected to the guide ring at an inner diameter of the cap by a snap-in connection. The cap has a first element of the snap-in connection, and the guide ring has a second element of the snap-in connection, said elements engaging into each other in a formfitting manner. The first element is designed as a two-component part, the soft component of which engages into the second element in a formfitting manner and the hard component of which forms a reinforcement of the soft component.

First claim

The invention claimed is:

1. A spring strut bearing comprising: a cap, a guide ring supported for rotation about a rotational axis (D) relative to the cap, an axial bearing between the cap and the guide ring, a seal on the cap and the cap is connected to the guide ring on an inner diameter of the cap by a snap-in connection, the cap including a first element of the snap-in connection and the guide ring including a second element of the snap-in connection, which engage in each other with a positive-fit connection, the first element is a two-component part including an axially extending sleeve having a soft component that engages with a positive-fit connection in the second element and a hard component that forms a reinforcement of the soft component, the soft component is relatively softer than the hard component, the soft component and the hard component forming the snap-in connection, the soft component including a radially extending projection, the hard component including an axially extending reinforcement and defining a radially innermost surface of the snap-in connection, and the radially extending projection being reinforced by the axially extending reinforcement.

2. The spring strut bearing according to claim 1 , wherein the hard component is provided on an inner diameter of the soft component.

3. The spring strut bearing according to claim 1 , wherein the hard component has a segmented design.

4. The spring strut bearing according to claim 1 , wherein the hard component extends over an entire inner diameter of the soft component.

5. The spring strut bearing according to claim 1 , wherein the hard component is a polyamide.

6. The spring strut bearing according to claim 1 , wherein the first element is constructed as a snap-on rim.

7. The spring strut bearing according to claim 1 , wherein the seal has a sealing element that forms a rubbing contact on the guide ring.

8. The spring strut bearing according to claim 1 , wherein the hard component extends along an entire radial inner surface of the soft component at the snap-in connection.
