Clutch Throwout Fork

The clutch throwout fork is a typical lever component-it amplifies the release bearing's thrust and applies it to the diaphragm spring fingers, achieving complete clutch disengagement with less pedal force. This part looks simple, but actually has high requirements for both rigidity and lightweighting: insufficient rigidity means excessive deflection under load and incomplete disengagement; too heavy increases drivetrain inertia. We make Clutch throwout forks to find the optimal balance between rigidity and lightweighting, for light pedal feel and complete disengagement.

We use high-strength ductile iron QT450-10 or medium-carbon alloy forged steel 40Cr as the base material-ductile iron offers good damping and cost advantages, forged steel offers high strength and impact resistance. The structure is optimized via finite element analysis: reinforcing ribs added in critical load areas, weight-reduction holes in non-load areas-thick where it needs to be, thin where it can be. Pivot pin holes and bearing contact surfaces are induction-hardened to hardness above HRC50 for wear resistance. Key dimensional tolerance ±0.03mm, pin hole position accuracy within 0.05mm. Clutch throwout forks are used in clutch control systems of passenger vehicles, commercial vehicles, and agricultural machinery, covering from microcars to heavy trucks. Every fork undergoes full dimensional and hardness inspection before shipping, and lever ratio verification and fatigue testing per customer requirement are available. Years of clutch parts manufacturing, OEM supply history. After years of making Clutch throwout forks, our insight is that fork rigidity and lightweighting must be balanced-enough rigidity for complete disengagement, light weight for light pedal feel, all optimized via finite element analysis. Send us your drawings; sample first to verify pedal feel.
