Clutch control system

Power line to drive a vehicle

Clutch control system in which the clutch actuation is initiated by

A control system for a rotary transmission for controlling pressure during speed ratio changes. The system includes a pump for delivering fluid under pressure which fluid selectively engages speed ratio selectors to enable the drive to be transmitted through the transmission. The system also embodies a regulator for regulating the fluid pressure in response to a throttle controlled torque demand signal. The system also includes sensors arranged to provide a signal to indicate the state of a speed ratio as well as a command signal to effect a change in the speed ratio.

A friction clutch driven plate has an annular friction facing with a back surface in contact with an opposed surface of a friction facing carrier. Circumferentially spaced recesses are provided in the back face of the facing so as to relieve the back surface of the facing to allow portions of the friction surface of the facing to yield under axial load on engagement of the driven plate against a drive member.

Friction clutch driven plates

A ratarder for a power transmission shaft comprises a liquid immersed coupling between the shaft and a drag member, the drag member being normally entrained to rotate with the shaft by viscous drag in the coupling. A dry brake mechanism, having a frictional drag greater than that of the coupling, is provided to restrain the drag member for relative movement to take place in the coupling. In the embodiments shown, the coupling comprises a friction disc pack alternately connected to the shaft and the drag member, the brake mechanism firstly restraining the drag member and subsequently shifting it axially to engage the friction disc pack. The coupling is suitable for use in heavy motor vehicle transmission systems.
