Abstract

A universal joint bearing with at least a first and a second elastomeric ring. The universal joint bearing is free from spiral springs, which exert a force on a portion of one of the elastomeric rings. The portion is provided for abutting against a trunnion of a crosspiece of a universal joint in a condition in which the universal joint bearing is part of the universal joint.

First claim

What is claimed is:

1. A universal joint bearing with at least a first elastomeric ring and a second elastomeric ring, the universal joint bearing comprising:
being free from spiral springs, which exert a force on a portion of one of the first elastomeric ring and the second elastomeric ring,
wherein the first elastomeric ring is force fitly fixed directly to an interior surface of the cup,
wherein the portion of one of the first elastomeric ring and the second elastomeric ring is provided for abutting against a trunnion of a crosspiece of a universal joint in a condition in which the universal joint bearing is part of the universal joint.

2. The universal joint bearing according to claim 1 , the first elastomeric ring further comprising at least two sealing lips.

3. The universal joint bearing according to claim 1 , one of the first elastomeric ring and the second elastomeric ring further comprising a sealing lip that abuts against a cup of the universal joint bearing.

4. The universal joint bearing according to claim 1 , one of the first elastomeric ring and the second elastomeric ring further comprising at least one sealing lip that extends mainly in an axial direction.

5. The universal joint bearing according to claim 1 , the universal joint bearing further comprising at least one metal ring that is directly fixed to the cup.

6. The universal joint bearing according to claim 5 , wherein the second elastomeric ring is fixed to the metal ring and provided for abutting against the trunnion in the condition in which the universal joint bearing is part of the universal joint.

7. The universal joint bearing arrangement according to claim 5 , the universal joint bearing arrangement further comprising the trunnion, wherein a gap between the cup of the universal joint bearing and the trunnion is sealed with a sealing that is free from the spiral springs.

8. The universal joint bearing according to claim 1 , the first elastomeric ring further comprising at least three sealing lips.

9. A universal joint bearing having at least a first elastomeric ring and a second elastomeric ring and a cup, the universal joint bearing comprising:
the first elastomeric ring including a sealing lip that abuts against the cup, and
the first elastomeric ring further comprising a second sealing lip that also abuts against the cup,
wherein the first elastomeric ring is force fitly fixed directly to an interior surface of the cup.

10. The universal joint bearing with at least the first elastomeric ring and the second elastomeric ring and the cup according to claim 9 , one of the first elastomeric ring or the second elastomeric ring further comprising at least two sealing lips that abut against the cup on a radially outer surface of the cup.
