Abstract: 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.

Abstract: A shaft/hub unit having a toothing assembly for transmitting torque, comprising a shaft (1) with shaft toothing (5) and a hub (2) with hub toothing (7), which sets of toothing engage one another, with torque being introduced by a shaft shank (4) at whose end there is provided the shaft toothing (5) and with the tooth profile of the shaft toothing (5), in the longitudinal direction, following a variable course, wherein the shaft toothing (5) comprises a major diameter which, in the longitudinal direction, follows a constant course and wherein the hub toothing (7) comprises a base diameter which, in the longitudinal direction, follows a constant course, wherein the toothing assembly comprises at least two axially extending portions (9, 10) in which each base diameter of the shaft toothing (5) follows a constant course and in which each major diameter of the hub toothing (7) follows a constant course, and wherein, of the each two adjoining portions, the portion facing the shaft shank (4) comprises the greater ba

Abstract: A rotational fixed connection has a shaft whose axial end is provided with outer shaft teeth and a hub whose through-bore is provided with inner teeth. The connection is useful between a driveshaft in the driveline of a motor vehicle and a joint hub of a universal tripod joint or a constant velocity universal ball joint. The joints include the hub, torque transmitting roller elements, and an outer joint part. The outer shaft teeth of the shaft, at a distance from the hub teeth end at the shaft shank end, run out steplessly into the shaft shank. The outer shaft teeth end inside the hub with a stepped end. In the region following the outer shaft teeth, the shaft includes a tooth-free end portion. The tooth-free end portion carries or forms fixing elements which axially securingly rest against a hub end face at the end where the shaft terminates.

Abstract: A freewheeling device (11) for torque transmitting purposes at small numbers of revolutions, e.g. at low driving speeds, has two freewheeling parts (14, 17) connected via locking members (25). The locking members (25) engage apertures (24) of one of the freewheeling part (17) and recess (26) of the other freewheeling part (14). If a certain speed of the two freewheeling parts (14, 17) is exceeded, one freewheeling part (14) may overtake the other freewheeling part (17). Switching is effected via a switching cage (29) loaded by centrifugal masses (33) and which moves a switching element (30) into the released position. A spring (36) ensures the transfer into the locked position. A synchronizing device (38) is provided in order to ensure that a transfer into the locked position takes place only at small speed differentials between the two freewheeling parts (14, 17).

Abstract: The invention relates to a freewheeling device 11 in the case of which the outer freewheeling component 14 and the inner freewheeling component 17 are connected in the main torque transmitting direction by locking members 25 which engage apertures 24 of the inner freewheeling component 17 and recesses 26 of the outer freewheeling component 14 and which permit one of the freewheeling components 14 to be overtaken by the other freewheeling component 17 when a certain speed is exceeded. If the speed is below the specified speed, an additional switching element is released via a speed-dependent switching device 29, so that the switching element 30, under the influence of a spring 36, is transferred into a position where it supports the locking member 25 to prevent them from escaping radially inwardly, thereby cancelling the freewheeling function.

Abstract: The invention relates to a locking device 4 for a freewheeling unit 1 of a non-directly driven axle of a motor vehicle driven by a directly driven axle. To lock the freewheeling unit 1 there is provided a first drive element 2 with a number of circumferentially distributed apertures 15 holding radially displaceable locking elements 16. The locking elements, for the purpose of establishing a non-rotating connection between the first drive element 2 and the second drive element 3, may partially enter recesses 17 of the second drive element 3 corresponding to the apertures. Radial displacement of the locking elements 16 is achieved by a spring loaded axially movable control element 10. Displacement of the control element 10 is achieved by radially outward displacement of centrifugal masses 20.

Abstract: A coupling for establishing a releasable torque transmitting connection between a hollow shaft element (1) and a journal element (2) positioned therein, by coupling members (13) provided in apertures in the hollow shaft element and radially movable therein to engage with recesses (39) in the journal element, and an operating sleeve (4) movable axially on the shaft element for effecting such radial movement of the coupling members, has radially displaceable locking members (12) for locking the operating sleeve axially in its coupling-engaged position, and a spring for providing a returning force against which the operating sleeve is movable to such position. The operating sleeve is moved axially by an electro-magnet (27, 28) which actuates an actuating ring (8) and locking sleeve (3) which acts on the locking members (12). The locking members and coupling members are preferably balls.

Abstract: A differential gear unit includes a viscous coupling for restricting the differential rotation of output gears (27, 29), with the conneciton of one of the parts (31) of the viscous coupling to one output gear being by way of a releasable connecting device so that the viscous coupling can be brought out of operation when required, e.g. under vehicle braking. The connecting device comprises a sleeve (1), coupling members (11) movable radially in the sleeve (1) to engage, when in radially outermost positions, groove (35) for torque transmission, and an actuating member (2) movable axially within the sleeve and operable on the coupling members. The actuating member (2) is movable by an axially displaceable positioning member (87, 49) through the intermediary of latching balls (68, 48) which are themselves radially displaceable to hold the actuating member in position without continuous application of a high force. The positioning member may be movable mechanically, electro-magnetically, or by fluid pressure.
