The first pair of guide rings is fastened to the torque input element by fastening members. These fastening members and the abutment member are both located radially inwardly of one of the two series of springs, and radially outwardly of the other series.

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.

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: For emergency operation of an automatic friction clutch (3) of a truck which is operated during normal running by an electronic controller (9) via an electric motor driven actuator (11) and a hydraulic system (19, 21, 23), it is proposed that the clutch be controlled manually via a compressed air actuator (29), in particular via a compressed air servo actuator, by means of a changeover valve (39) which connects the compressed air actuator (29) alternately to a compressed air source (37) or via a flow throttle (41) to the atmosphere.

Abstract: A driven disk assembly includes a hub assembly and a support plate assembly to which friction pads are attached. If the driven disk assembly includes a free travel feature wherein the hub assembly is free to rotate slightly with respect to the support plate assembly, it is difficult to align splines of the hub assembly with cooperating splines of a transmission input shaft upon installing a clutch including the driven disk assembly within a drive train. In order to negate free travel prior to installation, a small quantity of rupturable material is disposed within a slot that accommodates lost notion between the support plate assembly and hub assembly. Upon initially rotating the support plate assembly, the material ruptures, allowing relative motion between the support plate assembly and hub assembly so that the free travel feature and damping springs disposed between the assemblies function as intended.

Abstract: A friction type one-way clutch includes friction elements held by a retainer between an input side member and an output side member. The friction elements are released from frictional engagement with the input side and output side members to interrupt power transmission from the input side member to the output side member by rotating the retainer. For rotating the retainer, a rotor is formed on the retainer, and a stator having coils for generating a rotational magnetic field is disposed around the rotor. An electric current is fed to the coils of the stator to generate a rotational magnetic field, and the rotation of the rotor by this rotational magnetic field rotates the retainer.
