摘要:
A bushing-type roller overrunning dutch comprising an inner and/or outer ring (4), clamping ramps (2) adapted to the needles or rollers (5), a cage (6), pressure springs (7) for the needles or rollers (5), a bushing (1) with integrally formed clamping ramps (2), and a solid inner or outer ring (4) in or on which the bushing (1) is fixed.

A roller freewheel comprises an outer ring which is configured as a sheet metal part shaped without cutting and has a cylindrical outer surface and an inner surface which is provided with clamping ramps, a plurality of clamping rollers which are sprung against the clamping ramps, and a cage which is arranged fixedly in terms of rotation in the outer ring, is configured as a sheet metal part shaped without cutting and to which springs are fastened which are provided for suspending the clamping rollers.
摘要:
A bushing-type roller overrunning clutch comprising at least an inner or an outer ring that comprises clamping ramps adapted to the needles or rollers, said overrunning clutch further comprising a cage for the needles or rollers, as also pressure springs, said cage comprising cage elements that are made in one piece with the inner or outer ring, and a method of making a bushing-type roller overrunning clutch in which the inner or outer ring together with the clamping ramps and at least one border arranged on one side of the clamping ramps is made by deep-drawing, spring-retaining lugs are cut out of the border, and the spring-retaining lugs are bent radially towards the inner or outer ring and the free-standing tabs of the spring-retaining lugs are bent over into the region of the clamping ramps.

A parking lock (1) of a transmission comprises a parking lock wheel (2) that is rotationally fixed relative to a shaft (25) and a locking ring (3) that is rotationally fixed relative to a housing (24), the locking ring (3) can be displaced axially into a positive locked connection with the parking lock wheel (2) by an engaging element (4) and can be released from the locked connection by a hydraulically actuated release element (6).
摘要:
An overrunning clutch clamping body for an overrunning clutch comprises a first contact surface and a second contact surface for contacting respective clamping raceways. The curvature of the contact surfaces deviates from zero in each direction. Each of the contact surfaces is configured symmetrically both to a first plane (E1) extending normal to the axis of rotation of the overrunning clutch and to a second plane (E2) that is perpendicular to the first plane (E1), and the shape of the first contact surface corresponds to the shape of the second contact surface.
摘要:
An idler gear (7) is mounted in a variable speed gear transmission (1) on a rolling bearing crown ring (10) whose first and second rolling elements (12, 20) are guided in a cage (11) and have different diameters. The first and second rolling elements (12, 20) are of a same type, size ratios between the first and second rolling elements are defined so that, in an unloaded state, the larger diameter of the second rolling elements (20) is such as to become equal to a diameter of the first rolling elements (12) in an engaged state under radial loading, whereby a limit of elasticity of the second rolling elements (20) having the larger diameter in the unloaded state is not exceeded.
摘要:
A coupling arrangement (1) with a first clamping ring (10) concentric to the axis of rotation (1a), a second clamping ring (20) oriented concentrically with the axis of rotation and grooved around its circumference, and with clamping bodies (30) oriented radially between the clamping rings (10, 20); which includes on at least one of the clamping rings projections (11) that are built into a shape like a ramp (10, 20), each of which is placed between two neighboring clamping bodies; and which includes a first retainer (15) and a second retainer (25), with which the clamping rings (10, 20) and the clamps (30) are held together.
