Clutch Disc Springs

The Heart of the Clutch System

Clutch Disc Springs are the core part of a car clutch. They control the pressure between the pressure plate and the friction disc. The driver pushes the pedal. The spring changes the pressure. This lets the car change gears. Our product use a diaphragm design. This is a special large-diameter disc spring. It gives a precise force curve during engagement and release. We use 50CrVA or SUP6 alloy steel. We use precision stamping, heat treatment, and shot peening. Our product last as long as the car itself.

Pedal Feel and Clutch Performance

The design of a Clutch Disc Spring is very precise. When the clutch is engaged, the spring gives enough force. This stops the clutch from slipping. When the driver presses the pedal, the force must be reasonable. The pedal should not be too hard or too soft. We control the cone angle, window size, and thickness. This gives us the right force-deflection curve. Our Clutch Disc Springs are used by clutch makers in China. They have passed high-low temperature and fatigue tests. We have 28 years of experience with springs. This gives us the skill to make reliable product for both gas and electric cars.

The Main Cause of Breakage

Clutch Disc Springs can break for several reasons. Small flaws in the material can cause cracks. The hardness might be too high, making the spring brittle. The driver might use the clutch too much. This makes the spring overheat. The spring might also get damaged during installation. We check every Clutch Disc Spring with flaw detection. We control the hardness within a tight range. This stops most breakage problems. We also support PPAP and IMDS for our Clutch Disc Springs. This helps our customers meet auto industry standards.
