Abstract
A hydraulic fluid pressure operated torque transmitting assembly for use as a brake or clutch which utilizes hydraulic pressure operated cylinders in a housing moveable with respect to an axially stationary spring housing to move a pressure plate against rotating discs and reaction plates. Hydraulic fluid pressure disengages the torque transmission and loss of hydraulic pressure enables springs in the spring housing to move the pressure plate to engage the friction discs for torque transmission. Radially removable spacers permit the spring housing position on mounting studs to be adjusted for compensating for friction disc wear. The hydraulic cylinders each have a drain port communicating with an annular collector groove in the cylinder bore. The drain ports are interconnected through flexible conduits connected to a master drain port in the cylinder housing.
