Abstract: A suspension strut bearing (1) is provided with a vehicle-body attachment element (3) and a guide ring (5). A sliding bearing (9) or rolling bearing (11) that can rotate about a center axis (7) is arranged between the vehicle-body attachment element (3) and the guide ring (5). The guide ring (5) has at least one metallic reinforcement (17) and forms an axial and/or radial thrust bearing (13) for a coil spring (15). In addition, a manufacturing method for a component of a suspension strut bearing (1) is provided.

Abstract: The invention relates to a machine element which is provided, at least over part of its axial length, with first toothing (2.1) in the form of threads, running on its cylindrical lateral surface, for a threaded drive. This is distinguished in that the threads are produced by means of a continuous shape rolling process in the axial direction, as is known per se, the continuous shape rolling process being used in a partially continuous manner corresponding to the desired axial extent of the threads.

Abstract: An actuating unit for an electromechanically actuated disc brake for automotive vehicles which is composed of a drive unit or an electric motor, an actuating element forming one of two friction linings into engagement with a brake disc, and a reducing gear. A freewheel mechanism that interacts with the electric motor has the function of a parking brake. In order to ensure a high level of reliability in operation of the parking brake and to render it resistant to external influences, in particular, oscillations or vibrations, the present invention suggest that the freewheel mechanism be configured in such a way that its clamping effect is produced by a form-locking torque transmission and that, in its actuated state, it prevents a rotational movement of a bearing in which the rotor of the electric motor is mounted.

Abstract: In a threaded mechanism with rolling bodies comprising a spindle rod, a spindle nut at least partially enclosing said spindle rod, and a number of interposed rolling bodies, an axial and radial mounting support is provided for the spindle nut that is adapted to receive both tilting movements of the spindle nut about its longitudinal axis as well as radial movements transversely to its longitudinal axis.

Abstract: An adjusting device for disk brakes for compensating a play caused by wear comprises a support (6) received in a brake caliper (2) for displacenent transversely of the brake disk (1), an adjusting spindle (7, 8) being arranged for rotation and axial displacement in the support (6), said adjusting spindle comprising, on one end, a brake lining carrier (9) equipped with a brake lining (10), and said adjusting spindle being connected rotationally fast and axially displaceable to a shaft (17) which is engaged by a lever (15) via a clamping roller overrunning clutch (21) for transmission of an adjusting moment whereby an axially pre-tensioned coiled compression spring (22) is arranged crosswise to the turning direction of the lever (15) and is supported at one end on the lever (15) and at a second end on a stationary element (23).

Abstract: A device for damping torsional vibrations in a drive train of a traction drive connecting an internal combustion piston engine and an auxiliary unit, comprising an overrunning clutch (5,30,48) arranged between a driving pulley (2,25,42) and an input shaft (1) of the auxiliary unit or between a crankshaft and a driven pulley of the internal combustion piston engine, characterized in that the overrunning clutch (5,30,48) comprises an inner or outer ring (8,9,28,29,50) made of sheet metal without chip removal on which locking ramps cooperating with locking rollers (10,30a,48a) are formed, and the inner or outer ring (8,9,28,29,50) extends at least on one side beyond a region of the locking ramps to form a raceway for a rolling bearing (6,7,31,32,45,49).

Abstract: An overrunning clutch assembly inserted between a rotary driving element and a rotary driven element and comprising a locking element overrunning clutch and a radial rolling bearing arranged adjacent to each other with a gap therebetween, an axial securing arrangement provided for the two components of the overrunning clutch assembly comprising rims extending laterally from respective cages of the overrunning clutch assembly and the radial rolling bearing, characterized in that the axial securing (3, 3a to 3f) of the locking element overrunning clutch (2,20) and the radial rolling bearing (15,25) is effected in the gap (14, 14a to 14f).

Abstract: A free-running roller coupling transmits in both directions of rotation a torque between two structural members. This coupling has an outer ring in which clamping tracks are formed by recesses. An inner element has a cylindrical clamping track. Pairs of clamping rollers, prestressed by a pressure spring against the ramp-like end of each clamping track, are arranged between the clamping track of the inner element and the clamping tracks of the outer ring. An unblocking arrangement has comb-like carriers that extend through slots in an edge of the outer ring, which carriers can unblock the rollers while allowing the outer ring to be driven by a switching sleeve.
