PCT No. PCT/SE96/00937 Sec. 371 Date Jun. 1, 1998 Sec. 102(e) Date Jun. 1, 1998 PCT Filed Jul. 11, 1996 PCT Pub. No. WO97/04245 PCT Pub. Date Feb. 6, 1997Torque is transmitted between two rotatable, coaxial shaft members in a stationary housing which includes a number of alternate clutch discs connected to the shaft members and engageable to counteract differential rotational speed therebetween, and a hydraulic arrangement driven by the speed differential. The arrangement includes a number of pistons which are axially movable in the housing and are intended to create a hydraulic pressure in the arrangement and thereby to engage the clutch discs, piston actuating devices engaging a shaft member via cams, so as to impart to the pistons a reciprocating movement, and a closed hydraulic system connecting cylinders at all pistons with a hydraulic line containing check-valves. Oil is supplied to the system with a pump and may be removed from the system via an overflow valve. |
