The automotive clutch actuator is a device used in vehicles with manual transmissions to engage and disengage the clutch. It is responsible for controlling the movement of the clutch mechanism, which connects the engine to the transmission. The clutch actuator is usually a hydraulic, pneumatic, or electromechanical system that is activated either by the driver pressing the clutch pedal or by an automated system in vehicles with automated manual transmissions (AMT) or dual-clutch transmissions (DCTs). The actuator applies force to the clutch mechanism, allowing the clutch disc to either engage or disengage from the flywheel, thus enabling smooth gear changes and the transfer of power between the engine and the transmission.
