ABSTRACT:
A torque transmission device coaxially arranged between a pair of rotary shafts transmits rotational torque in response to relative rotation therebetween. This device includes an outer cylindrical housing coupled to one of the rotary shafts for rotation therewith, wherein the outer cylindrical housing receives an inner sleeve shaft coupled to the other of the rotary shafts for rotation therewith, and multiple friction disc clutch which transmits rotational torque between the inner sleeve shaft and the outer cylindrical housing. In the torque transmission device, there are also an actuation piston making the multiple friction disc clutch be in engagement and a pressure generating mechanism generating a pressure according to the relative rotation between the outer cylindrical housing and the inner sleeve shaft to make the actuation piston move toward the clutch. Further, the torque transmission device has a pressure controlling mechanism which controls the pressure in the clutch chamber receiving the clutch so that the characteristic of the torque transmission device is changed.
