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.

Actuating unit for an electromechanically actuated disc brake

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

Freewheel cage with reinforcing ring

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).

Device for damping torsional vibrations in a drive train

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).

Overrunning clutch assembly

Clutch designed as roller free-wheel for transmitting a torque acting in

A cage for an overrunning clutch with a metallic outer race accommodating concentrically a metallic inner element and having in a cage arranged between the outer race and the inner element camming elements retained under the action of springs in camming contact with the surfaces of the outer race, on the one hand, and of the inner element, on the other hand, the cage being made of injection moldable or castable polymeric material and having pockets for the camming elements defined by crossbars and at least one end ring connected therewith, at least one circumferential surface of the cage cooperating in the form of a sliding bearing with a cylindrical surface of the adjacent structural part (outer race and/or inner element), characterized in that the cage (1,15,22,30,39) is provided at least in the area of the end ring (4,18,23,33,45) with an annular metallic reinforcement shield (13,19,20,26,27,34,35,47) connected to the cage (1,15,22,30,39) in a form-fitting manner especially through injection-molding around the shield and whose temperature expansion coefficient corresponds essentially to that of the outer race (5,40) and the inner element (9,41).

Cage for overrunning clutch

A one-piece sheet metal cage for an overrunning roller clutch wherein the cam rollers roll between a smooth inner races and an outer race provided with camming surfaces comprising a U-shaped sheet metal element provided in its longitudinal section with radial ends of different height, the higher end engaging the camming surfaces in a locking manner with a corresponding outer profile and the cage is provided with folding springs on radially directed segments on the cross-bars forming the cage pockets which cause the cam rollers to bear against an inner and outer retaining element of an adjacent cross-bar, each said cross-bar comprising a short segment extending in the circumferential direction at the bottom of the U-profile which forms the inner retaining elements at its axial ends adjoining the end flanges connecting the cross-bars and a flap between the inner retaining elements bent radially outward to which is secured a folding spring engaging an opening of the flap with an elastic projection, said flap being provided at its two axial ends with bent outer retaining lugs.
