Abstract: A roller freewheel includes a roll body cage, a plurality of roll bodies accommodated in the roll body cage, and a ramp ring having a ramp contour. The ramp contour blocks the roll bodies in a first direction of rotation and allows rotation of the roll bodies relative to the ramp ring in a second direction of rotation, opposite the first direction of rotation. The ramp contour is designed to accommodate a plurality of roll body rows. The roll body cage includes a plurality of separate partial cages, with each partial cage including at least one roll body row.

Abstract: The present invention relates to a freewheel (2) having a first race (16), a second race (18), a clamping gap (20) formed between the first and second race (16, 18), at least one clamping element (30) in the clamping gap (20) and a pre-tensioning device (32) for pre-tensioning the clamping element (30) in a clamping position inside the clamping gap (20), wherein the pre-tensioning device (32) has a spring element (34) supported indirectly or directly on the first race (16). The pre-tensioning device (32) further has a spring support frame (36) that can be moved in relation to the first race (16), in which spring support frame the spring element (34) is arranged.

Abstract: A jamming roller lock with a housing and at least two jamming discs, which are arranged in the housing such that they can be rotated and which each comprise at least one recess, in which a jamming roller is located, at least one driving projection and at least one driven projection, wherein the jamming discs are arranged and designed in such a way that a rotation of the jamming discs can be achieved by driving the driving projections and a rotation of the jamming discs is prevented by driving the driven projections.

Abstract: A one-way clutch is designed to minimize parasitic drag in the over-running condition. Rollers are positioned radially between an inner ring and outer ring and rotate with the inner ring. Positioning pins push the rollers up ramps on the inner ring into contact with the outer ring. In the locked mode, the outer ring also tends to push the rollers up the ramps into tighter contact. In the over-running condition, the outer ring tends to push the rollers down the ramp, against the force of the positioning pins, and away from contact. Each positioning pin includes a ball which is rotatably held in a retainer via microspheres. The ball is in rolling contact with the roller, as opposed to sliding contact, thereby limiting parasitic drag.

Abstract: Disclosed is a freewheel (4) comprising a first race (38), a second race (40), a clamping gap (46) designed between the first and second race (38, 40), at least one clamping element (48) in the clamping gap (46), and biasing feature (64) for biasing the clamping element (48) into a clamping position within the clamping gap (46), wherein the biasing feature (64) have an accordion spring (66), which is supported directly or indirectly on the first race (38) and which comprises corrugation peaks (70) lying radially outward, corrugation troughs (72) lying radially inward, and a support leg (76) for direct or indirect support on the clamping element (48). In addition, disclosed is a freewheel arrangement (2) comprising such a freewheel (4).

Abstract: A clutch is provided that includes an inner race and an outer race that moves relative to the inner race. A pedestal is also provided and the position of the pedestal is fixed with respect to at least one of the inner race or the outer race. A bearing block is also included that engages the pedestal. In some versions of the clutch the bearing block may be made out of plastic or bronze.

Abstract: A one-way clutch includes an outer race, an inner race which is spaced from the outer race in an inside diameter direction and arranged concentrically so as to be relatively rotatable, a plurality of engaging members which are arranged between the outer race and the inner race to transmit a torque, and a cage which retains the engaging members. The one-way clutch is provided with volute springs which urge the engaging members in the direction in which the engaging members engage with a cam face of the outer race or the inner race.

Abstract: A one way clutch comprises an outer race including pockets having a cam surface and projecting portions disposed inwardly in a radial direction and extending toward an inner race; the inner race disposed away from the outer race in an inner diameter direction, relatively rotatably disposed concentrically with the outer race, and having an outer peripheral surface; torque transmission members arranged in the pockets to transmit a torque between the cam surface of the outer race and the outer peripheral surface of the inner race; springs for urging the torque transmission members in such a direction that the torque transmission members mesh with the cam surface of the outer race; and bearing members arranged between the outer race and the inner race and interposed between the projecting portions of the outer race and the outer peripheral surface, of the inner race.
