Abstract: A transmitting torque limiting apparatus, used in a power transmitting apparatus, includes side gears (40) and side gears piece (42) one of which are axially shiftable. The side gears (40) and the side gear pieces (42) respectively have first engaging teeth (60a) and second engaging teeth (60b) each being provided with a pressure angle (Alpha).

Thus, inputting of the excessive torque into the power transmitting apparatus can be limited.

A first actuator including an electromagnetic coil is supported on the case for moving the locking member toward engagement with the side gear in response to energizing the coil. A second actuator urges the locking member away from engagement with the side gear.

Abstract: A differential mechanism having two output cam members, each having a single annular cam surface with pairs of inclined surfaces. Relative contra rotation of the output cam members cause cam followers to slide axially, and a housing engages the cam followers which are slideably supported by the housing moving the followers circumferentially relative to the output cam members. The two cam output members are thrust axially against the housing during drive of the cam output members through the followers and at least one cam output member acts against the housing through a friction thrust washer. This mechanism allows control of the torque ratio between inside and outside output shafts of a vehicle when turning a corner.

Abstract: In a clutch (6) for locking a differential gear for a vehicle, a movable half (60) of the clutch (6) is pushed indirectly via a sliding sleeve (70) and intermediate members (77) in an engaging direction. Then the sliding sleeve (70), with a locking surface (74), retains the intermediate members (77) firmly in a locking position between a bearing surface (64) of the movable half (60) and an axially stationary retaining surface (4). Flanks (52, 62) of clutch teeth (51, 61) of an axially stationary half (50) and of the movable half (60) form in the axle direction a deflection angle (55). The bearing surface (64) and the retaining surface (4) form a wedge angle (65). The locking surface (74) of the sliding sleeve (70) is inclined in an axial direction forming a small releasing angle (75). To open the clutch (6), the sliding sleeve (70) is pulled away. A torque produces through the deflection angle (55) an axial deflection force which then disengages the clutch (6).
