The ConAct pneumatic release cylinder, which is positioned concentrically around the transmission input shaft, replaces the widespread fork actuation with clutch booster, fork and clutch release bearing.
SACHS ConAct is suitable for fully automatic systems and clutch-by-wire applications. In automated transmissions, the system automatically determines the engine and transmission speed data from the CAN bus. From the accelerator pedal position, conclusions can be drawn regarding the optimal releasing position. This works even in demanding driving situations such as maneuvering, launching and shifting on hills with a heavy load or on a slick road. Driven by the vehicle electronics, the solenoid valve controls the clutch actuation system.
