ABSTRACT:
A hydraulic actuating system for disengaging a clutch, shifting gears in a transmission and reengaging the clutch for a vehicle. An electric pump delivers hydraulic fluid under pressure to an accumulator. High and low pressure switches control operation of the pump to maintain the hydraulic fluid pressure within a desired range, while limiting operating time of the pump and minimizing energy waste. The pressurized fluid from the accumulator is applied through valves to operate a clutch actuating mechanism and to shift transmission gears. A secondary accumulator is provided at the clutch actuating mechanism to provide smoother clutch reengagement with a low cost valve having a relative coarse modulation capacity.
