Abstract
A support bearing for a vehicle is provided that includes, but is not limited to a rubber bearing that encloses one end of a strut element and introduces the lateral and longitudinal forces of the strut into a vehicle body. A ball bearing allows rotational movements between a spring element and the car body. For this purpose, the ball bearing of the support bearing is supported on the car body with a ball bearing race that features a first ball track. A second ball track of the ball bearing is arranged on a rubber bearing housing together with one end of the spring element.
Claims4
A support bearing for a vehicle, comprising:
- a strut element;
- a rubber bearing comprising an elastic rubber element enclosing one end of the strut element, and introducing a lateral force and a longitudinal force of a strut into a body of the vehicle;
- a ball bearing adapted to permit rotational movement between a spring element and the body of the vehicle, wherein the ball bearing is supported on the body of the vehicle with a first ball bearing race comprising a first ball track and a second ball bearing race arranged on a rubber bearing housing with an end of the spring element, wherein the ball bearing provides angular contact with the first ball bearing race and the second ball bearing race at an angle that is not parallel to the axial direction of the strut element;
- a shoulder arranged on the rubber bearing housing, the shoulder being substantially L-shaped when viewed in cross-section and having a vertical leg adjacent to said rubber bearing housing and a horizontal leg extending radially away from said rubber bearing housing;
- wherein the first and second bearing tracks comprise respective upper and lower bearing tracks that are substantially L-shaped when viewed in cross-section;
- wherein the upper bearing race comprises an outer portion that extends below a center line of the ball bearing, which forms a lower leg of the substantially L-shaped bearing tracks, and said upper bearing race further comprises an inner portion with a substantially horizontal portion that forms a horizontal leg of the substantially L-shaped bearing tracks;
- and
- wherein a bottom portion of the lower bearing race is arranged on the horizontal leg of the shoulder and wherein an inner portion of the lower bearing race is adjacent to the rubber bearing housing;
- and
- wherein the strut is a pneumatic strut.
The support bearing according to one of the preceding claims, wherein the pneumatic strut comprises a central telescopic rod having one end detachably fixed in a center of the rubber bearing of the support bearing.
