The disclosure relates to an overrunning clutch, comprising a torque-introducing clutch element, a torque-receiving clutch element and switching element, which is forced from an engagement position into a freewheeling position or from a freewheeling position into an engagement position in dependence on the direction of a sufficient change in the rotational angle position between the torque-introducing clutch element and the torque-receiving clutch element by means of an actuating force applied to the switching element by an actuator. According to the disclosure, the actuating force is a friction-induced actuating force, which is induced by means of a friction-force pairing between the actuator and a component of the overrunning clutch that is in frictional contact with the actuator and the actuator forms an interlockingly acting actuating stop, by means of which the actuating force acts on the switching element.

In an overrunning clutch, a clutch link axially overlaps another clutch link and a control element of a control mechanism, via which the axial displacement of a connecting link acting between the clutch links is initiated, is arranged on the radial inside of the overlap on the connecting link. The overrunning clutch is particularly suitable for use in a drive train of a motor vehicle and which can transmit high torque despite compactness in structure, operates extensively without noise in the overrunning direction, and has only low mass to be moved during a shifting process.

An inner joint part of a tripod constant velocity joint comprises a hub having an axis of rotation. Three projections extend radially outwardly. There is an adjoining transition region and a bearing region. A spherical circumferential surface of each projection forms a first surface line extending in a first plane. A resulting inner sphere contacts opposite points of the first surface line extending at least in first angle ranges adjacent to a respective point outside the inner sphere. A second surface line in a second plane touches the inner sphere at touch points only at the height of the largest diameter of the projection and extends at least in second angle ranges adjacent to the respective touch point within the inner sphere. A roller element has a convex inner circumferential surface, an extension line forming a radius having a maximum magnitude in a central region, less in an adjacent region.

A plate carrier for a multi-plate clutch comprises: an annular member with a first circumferential face and a second circumferential face; a toothing in the first circumferential face of the annular member, having circumferentially distributed teeth and gaps; at least one groove in the second circumferential face of the annular member, wherein the groove extends over a circumferential portion of the annular member, wherein the groove and the toothing intersect one another, so that radial apertures are formed in the regions of intersection between the groove and the tooth gaps. A multi-plate clutch can be provided with such a plate carrier.

Plate carrier

A method for manufacturing a toothing on a component of a shaft/hub connection is disclosed. The component may be held permanently in a chucking while it receives an at least two-stage toothing in this chucking. A special draw die for carrying out the method is also proposed, a first toothing-forming region with a first height and at least one following second toothing-forming region with at least one second height being arranged between a first and a second end face, and the first height being designed to be lower than the second height.

Manufacture of a shaft/hub connection

A tripod joint is disclosed which has an outer joint part and an inner joint part. The outer joint part includes a first longitudinal axis and a longitudinally running cavity with an open end. Three longitudinally running recesses are formed in the outer joint part. The inner joint part includes a second longitudinal axis and comprising at least one central body on which are integrally formed three journals with journal axes which extend radially from the second longitudinal axis. In each case, one roller body is arranged on the journals, which roller body has at least one outer ring, a closed inner ring and bearing bodies which are arranged in between. Each roller body is additionally, in each case, held in the recesses in a longitudinally moveable manner, and a rotation of the closed inner ring about the respective journal is blocked. Also proposed is a roller body with a non-circular or angular inner ring.
