A transmission unit includes a transmission housing, a transmission element rotatably accommodated in the transmission housing, a bearing seat, and an angular contact ball bearing accommodated in the bearing seat, for mounting the transmission element, as well as a double-row angular contact ball bearing having: an inner bearing ring; an outer bearing ring; a first ball-cage assembly with first balls which are accommodated in a first track space extending between a first inner rolling element raceway of the inner bearing ring and a first outer rolling element raceway of the outer bearing ring; and a second ball-cage assembly with second balls which are accommodated in a second track space extending between a second inner rolling element track of the inner bearing ring and a second outer rolling element track of the outer bearing ring.

Transmission unit, in particular an axle drive or transfer case, having a transmission element mounted therein via at least one double-row angular contact ball bearing

A clutch release bearing device having an interior and an exterior raceway. The exterior raceway is equipped with a ring wall being retracted underneath the path radius of an inner roller body raceway. An interior sealing device is provided, including a ring element axially supported on an inner radial wall section of the retracted ring wall.

Clutch release bearing and method for the production thereof

A clutch release bearing () that is in contact with a disk spring is provided. The clutch release bearing () includes at least one curved contact surface () that is located at a radial distance from the axis of rotation () of the clutch release bearing () and is used for contacting at least one end () of at least one spring tongue () of the disk spring.

Clutch release bearing in contact with a disk spring

A clutch operator for a disconnectable clutch useful in a motor vehicle, and having a self-adjusting release bearing supported on a housing and in the form of a rolling-contact bearing designed as an inclined-shoulder bearing. The bearing has an outer bearing ring, a rotating inner bearing ring and rolling bodies guided between the rings. An adjusting ring at the inner bearing ring. A sliding element in a supporting region of the adjusting ring on the inner bearing ring, and being in the form of complementary spherical-cap segments. A noise-reducing and wear-reducing coating, on which a spring element connected to the disconnectable clutch is supported at a radially oriented annular flange of the adjusting ring.

A clutch release bearing includes a housing, a first bearing ring having a skirt for fixed rotative securement of the first bearing ring to the housing, a revolving second bearing ring connected to the separating clutch via a spring element, and a plurality of rolling elements guided between the first and second bearing rings. Seals are provided on both sides of the rolling elements at a distance thereto and involve a sealing arrangement which is securely fixed to the housing and comprised of at least two components to establish two sealing zones for sealing an annular gap between the first and second bearing rings. The sealing arrangement cooperates with a planar surface of the revolving bearing ring and assumes a desired position, when the revolving bearing ring is installed with the assistance of a press-fit tool.

Clutch release bearing with improved sealing arrangement

A self-adjusting release bearing in the form of a tapered rolling bearing for a separating clutch disposed between an internal combustion engine and a gearbox of a motor vehicle, includes a non-rotating first bearing ring, a revolving second bearing ring, and a plurality of rolling elements guided between the first and second bearing rings. Supported upon a calotte-shaped section of one of the first and second bearing rings in a contact zone is an adjustment ring having a complementary calotte-shaped section to thereby allow pivoting of the release bearing, whereby a sliding element made of thermoplastic material is disposed in the contact zone.

Self-adjusting clutch release bearing

A clutch release bearing includes a housing, a first bearing ring having a skirt for fixed rotative securement of the bearing ring to the housing, a revolving second bearing ring connected to the separating clutch via a spring element, and a plurality of rolling elements guided between the first and second bearing rings. Seals are provided on both sides of the rolling elements at a distance thereto, wherein one seal is configured to seal an annular gap between the first and second bearing rings and includes a sealing arrangement which is securely fixed to the first bearing ring and comprised of at least two components to establish two sealing zones, wherein the second bearing ring and the sealing arrangement interact in such a way that a desired installation position of the sealing arrangement is automatically establishes as the second bearing ring is installed.

A release bearing includes a rolling-contact bearing having a non-rotatable outer ring, a rotating inner ring, and plural rolling members located between the outer and inner rings. The inner ring is intended to interact with an adjustment ring which has a ring flange for abutment against a disk spring of a clutch mechanism. Disposed in a support zone between the inner ring and the adjustment ring is a sliding element whereby the support zone is configured in the form of complementary calotte-shaped portions so that the adjustment ring and the inner ring are movable relative to one another for effecting a self-adjustment of the release bearing.

A release bearing for a separating clutch installed in a motor vehicle, includes a casing movable in an axial direction and operatively connected to an actuating mechanism, a non-rotatable bearing ring having a ring bottom supported by the casing; and a revolving bearing ring having a annular flange. Guided between the bearing rings is a plurality of rolling elements. An engagement disk made of a low-friction and wear-resistant material is securely fixed to the annular flange, and a spring member is operatively connected to the separating clutch and cooperates with the annular flange of the revolving bearing ring, wherein the spring member bears against the engagement disk.

Release bearing with improved connection to a separating clutch

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.
