Throwout Fork

The throwout fork is the main lever in the clutch system, transmitting force from the release bearing to the clutch diaphragm spring. We manufacture it from high-strength ductile iron or precision-forged steel. Its structure is optimized using finite element analysis, providing high stiffness and excellent fatigue strength. The well-positioned pivot point and lever ratio reduce the pedal force required to fully disengage the clutch, easing driver effort. The release motion is smooth and consistent, delivering a clear engagement point and better control.

This fork is compatible with both mechanical and hydraulic clutch systems and fits a wide range of vehicles, from small cars to heavy trucks. Its performance ensures full clutch disengagement and smooth gear shifts. It withstands frequent partial engagement in urban traffic and handles the high release forces of powerful engines. The throwout fork provides reliable and efficient force transfer, helping protect the clutch system from unnecessary wear.

We use high-strength ductile iron such as QT450-10 or QT600-3, depending on load requirements. For more demanding applications, medium-carbon forged steel like 40Cr is used. Critical areas, such as bearing contact points and pivot pin holes, undergo local hardening to resist high contact stress. Each batch undergoes mechanical testing and full dimensional inspection. Bench fatigue tests simulating real-world conditions ensure the fork maintains strength and shape throughout the vehicle's service life.

The fork's geometry-including arm curvature, pivot point, and bearing groove size-is carefully designed to fit the clutch assembly and housing. We offer full engineering support and customization. Our team can adjust lever ratios and structural strength to meet your clutch system requirements, resulting in a more comfortable pedal feel and a more reliable overall system.
