摘要： A vehicle driveline assembly (10) for an automotive vehicle includes a differential assembly (26) adapted to transfer torque proportionally between first and second axle half-shafts (28,30). An over-running clutch (34) is adapted to selectively lock the differential assembly (26) thereby effectively rotationally locking the axle half shafts (28,30) to one another. The differential (26) has three modes of operation; an open mode, wherein the differential is kept un-locked; a locked mode, wherein the differential is kept locked; and an automatic mode, wherein the differential is locked or un-locked based upon predetermined operating parameters. A selector switch (90) allows an operator to selectively place the differential (26) in one of the three modes. An electronic control unit (92) receives inputs from the vehicle, compares the inputs to pre-determined operating parameters, and selectively engages or disengages the over-running clutch (34) when the differential is in the automatic mode.

摘要： An over-running clutch (10) includes an outer race (12) and an inner race (20) defining a gap (24) therebetween. A plurality of rolling elements (26) are positioned between the inner and outer races. A retainer (28) interconnects the rolling elements. A first biasing element (34) biases the retainer to hold the rolling elements such that the inner and outer races are free to rotate relative to one another. An actuator (42) selectively forces the rolling elements to a position where the rolling elements engage and wedge between the inner and outer races, thereby locking the clutch. A sensor (52) is adapted to detect the engagement of the clutch and to send a corresponding signal.

摘要： A reservoir chamber (13) is defined between the cylinder (1) and the sleeve (4), and a check valve (15) is provided on the path (14) communicating the reservoir chamber (13) with the pressure chamber (6). The check valve (15) closes the path (14) when pushing force is applied and the cylinder (1) and the rod (5) retract relative to each other, and thus the pushing force is buffered by hydraulic oil in the pressure chamber (6). A communicating path (16) communicating the pressure chamber (6) with the reservoir chamber (13) is formed in the rod (5), and a relief valve (18) is mounted in the communicating path (16) to keep the upper limit of the pressure in the pressure chamber (6) constant so that excessive tension is not applied by the rod (5) to the belt (41). A throttle (34) is provided on the outlet side of hydraulic oil of the relief valve (18). This keeps pressure difference between inlet and outlet of the hydraulic oil small when relief valve (18) opens, and thus prevents vibration of a valve body (23) of the relief valve (18).
