Description
Definition:
The Swing Fork 637998, also known as a release fork or clutch fork, is a pivotal lever mechanism within the clutch system of a Claas combine harvester. It is typically mounted on a pivot ball and acts as the crucial mechanical link between the clutch actuator and the clutch release bearing.
Primary Functions:
-
Force Transfer and Actuation: The primary role of the swing fork is to transfer the actuation force from the clutch control system (hydraulic slave cylinder or cable) and direct it onto the clutch release (throw-out) bearing. It converts the initial push or pull into a precise prying action.
-
Engagement and Disengagement Control: It is the component that physically pushes the release bearing forward to disengage the clutch. This action presses the bearing against the diaphragm spring fingers of the pressure plate, releasing the clutch disc and interrupting power flow to the transmission.
-
Providing Mechanical Leverage: The fork is designed to provide a mechanical advantage. It amplifies the force received from the clutch actuator, ensuring that sufficient force is applied to the release bearing to overcome the strong spring pressure of the clutch cover assembly.
-
Bearing Guidance and Alignment: It serves as a guide and support for the release bearing, holding it in correct alignment on the transmission input shaft bearing retainer. This ensures smooth, linear movement of the bearing and prevents misalignment, which could lead to premature wear or failure.
