The clutch fork is a crucial actuating component in the transmission system of manual transmission vehicles; its main function is to, through the principle of leverage, push the clutch disengagement bearing when the driver operates the clutch pedal, thereby separating the clutch disc and the driven disc, cutting off the power transmission between the engine and the transmission, thus facilitating gear shifting operations; when the pedal is released, it returns to its original position under the action of the return spring, allowing the clutch to re-engage and restore power transmission.
Their structures are mostly fork-like or lever-like, typically made of high-strength cast iron or forged steel, with one end connected to a clutch disengagement bearing and the other end linked to a clutch push rod or a pull wire; they need to have sufficient rigidity and wear resistance to endure frequent thrust loads.
The precise movement of the shift fork has a direct impact on the disengagement and engagement of the clutch, and if it deforms or wears out, it can lead to difficulties in shifting gears and clutch slippage.
In terms of design, it is crucial to ensure that there is a reasonable clearance between the shift fork and the split bearing, as well as the push rod, and some models may also be equipped with bushings to reduce friction and extend the lifespan of this component, which is vital for ensuring smooth shifting in manual transmission vehicles.
