Clutch Kit

A clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft.

In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work. While typically the motions involved are rotary, linear clutches are also possible.

In a torque-controlled drill, for instance, one shaft is driven by a motor and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the same speed (engaged), locked together but spinning at different speeds (slipping), or unlocked and spinning at different speeds (disengaged).

Clutch Components by Exedy

Pull type cover

Ordinary clutch covers are designed to push for disengagement, EXEDY’s patented pull type cover does the opposite. The Pull type clutch cover accommodates higher torque, in conjunction with lighter pedal efforts to produce a superior clutch operation. It is particularly effective for high powered vehicle applications.

Peak cut cover

LPEC cover

pull type cover
LPEC stands for Light Pedal Effort Cover, and is used to relieve pedal effort in vehicles where higher engine torque requires an increased pedal effort. The LPEC cover was designed to reduce the pedal effort when engaging the clutch throughout the clutch’s life. The LPEC design reduces the release load compared to conventional clutch covers by increasing the lever ratio.

Lever type clutch cover

The Lever Type Clutch Cover is designed with push lever arms for clutch disengagement. This design is mainly used by large vehicles such as trucks and buses.

Silent type disc

pull type cover
EXEDY’s silent type disc has been cleverly designed utilising technology to reduce gear noise caused at acceleration, deceleration and idling. On acceleration it is possible to reduce gear rattle for front wheel drive vehicles by controlling it with low torsional rigidity and high hysteresis torque. At deceleration it is possible to move the resonance frequency point to lower engine rotational speed which makes smaller rotational fluctuation. On idle it is possible to improve the gear rattle by using low torsional rigidity and low hysteresis torque.

WAD disc

pull type cover WAD (Wide Angled Damper) discs are designed to correspond with high engine fluctuation in diesel and direct injection applications, the WAD uses high performance damper technology to absorb noise and vibration.

Dual mass flywheel

The Dual Mass Flywheel was designed by EXEDY for applications with high torque engines, used commonly when engine size has been reduced. The dual mass flywheel secures damping functionality at low speeds in order to reduce CO2 emissions and increase gas mileage.

The features of the dual mass flywheel are:

  • To decrease the harshness of operation and sound of transmission gear rattle.
  • To secure strength at low resonance speed.
  • To decrease the sound of the damper operation.
  • Secure pressure plate lift.
  • Improvement of engine start at low temperature.
