摘要： A detent mechanism that acts between two components that rotate with respect to one another to control rotation from a first set position to at least a second set position. The detent mechanism (10) comprises at least one rotating cam (23) positioned between adjacent surfaces of two components (11 and 16). The cam (23) is spaced from the axis of rotation of the two components (11 and 16). The cam (23) is journalled for rotation on one of the components (11) about an axis that is substantially transverse to the axis of rotation between the two components (11 and 16). The operating surface (25) of the cam (23) comprises at least one cam lobe that is caused to rotate as the two components (11 and 16) rotate. The cam (23) acts to separate the two components (11 and 16). Spring (17) acts to urge the adjacent surfaces together so that a predetermined torque is required to cause relative rotation between the components (11 and 16). The torque is set by the force applied by the spring (17) that results from the extent of compression of the spring (17) when the two components (11 and 16) separate upon rotation. The advantage of the detent mechanism (10) is that sufficient resistance to rotation can be obtained with a relatively light spring (17) due to the high rate of lift provided by the cam (23).

摘要： An apparatus for transfer of a torque from an internal combustion engine to an auxiliary unit has an auxiliary unit shaft and a pulley rotatably disposed on the auxiliary unit housing. The pulley and the auxiliary unit shaft are connected with one another by an overload protection device configured to interrupt the connection between the pulley and the auxiliary unit shaft if a predetermined torque is exceeded. The overload protection device has a spring washer having multiple spring arms connected, on the end side, with connection elements of a disk-shaped driver until the predetermined torque is reached. Each connection element is configured as a pocket-shaped mounting in the driver, wherein the respective spring arm end lies against a contact surface of the pocket-shaped mounting under spring tension, with force fit. The respective pocket-shaped mounting is configured as a hook-shaped crosspiece cut out of the driver in certain regions.

摘要： An overload clutch or coupling includes a hub section connected to one drive element and a housing connected to another drive element. Plungers are fitted in sockets in the housing such that the shank portions of the plungers project from one side of the housing and conical end faces project from the other side of the housing where they engage with plunger seats on the hub. The hub has pull pin sockets that receive spring-biased pull pins and apply a force to a pressure plate that acts on the projecting shank portions of the plungers to maintain them in the plunger seats. The plungers are displaced from the seats when the torque between the hub and housing exceeds the maximum torque to be transmitted by the coupling or clutch. The housing can slide along the plungers to accommodate floating movement between the driven and driving parts of the clutch or coupling. A keeper plate is attached to the hub to retain the housing against such floating axial movement when desired. A pinion gear carried by a clamp ring attached to the hub meshes with a hub gear for index positioning.
