Abstract
A release bearing includes a rolling-contact bearing having a non-rotatable inner ring, a rotating outer ring, and plural rolling members located between the inner and outer rings, An adjustment ring having a ring flange is provided for abutment against a disk spring of a clutch mechanism, and a sliding element made of bearing material is disposed in a support zone defined between complementary calotte-shaped portions of the outer ring and the adjustment ring so that the adjustment ring and the outer ring are movable relative to one another for effecting a self-adjustment of the release bearing.
Claims22
A release bearing, comprising:
- a rolling-contact bearing having a non-rotatable inner ring, a rotating outer ring, and plural rolling members located between the inner and outer rings;
- an adjustment ring having a ring flange for abutment against a disk spring of a clutch mechanism;
- and
- a sliding element made of bearing material and disposed in a support zone, which is defined between complementary calotte-shaped portions of the outer ring and the adjustment ring so that the adjustment ring and the outer ring are movable relative to one another for effecting a self-adjustment of the release bearing,
- wherein the adjustment ring and the outer ring are made as a deep-drawn part of steel and combined with the sliding element to a unitary structure, wherein the sliding element is made of a wear-resistant and high-temperature-resistant plastic.
A release bearing comprising:
- a rolling-contact bearing having a non-rotatable inner ring, a rotating outer ring, and plural rolling members located between the inner and outer rings;
- an adjustment ring having a ring flange for abutment against a disk spring of a clutch mechanism;
- and
- a sliding element made of bearing material and disposed in a support zone, which is defined between complementary calotte-shaped portions of the outer ring and the adjustment ring so that the adjustment ring and the outer ring are movable relative to one another for effecting a self-adjustment of the release bearing, wherein the sliding element is operatively connected to the outer ring.
