Abstract:
An electro-hydraulic clutch system for a motor vehicle includes a clutch mechanism that selectively engages an engine of the motor vehicle with a gear box, an actuator that pumps and retrieves hydraulic fluid to and from the clutch mechanism to activate the clutch mechanism, and a solenoid with a valve and/or a check ball that is disposed in the path of the hydraulic fluid between the actuator and the clutch mechanism. The solenoid has a normally closed position to prevent flow of the hydraulic fluid back to the actuator in the event of a system failure. The solenoid can also be used to reduce energy consumption in steady state conditions.
