As a leading name of Extendable Conveyors, we have achieved great laurels for our company. In automotive applications, this is often provided by a mechanism in the clutch disc centres. In addition to the damped disc centres, which reduce driveline vibration, pre-dampers may be used to reduce gear rattle at idle by changing the natural frequency of the disc. It is a device that softens the response of the clutch engagement/disengagement. These weaker springs are compressed solely by the radial vibrations of an idling engine.
