What is a pre dampened clutch?

What is a pre dampened clutch?

The Pre-damper feature consists of a set of small springs around the hub, which dampen the engine torsional vibrations at idle speeds before they can reach the transmission and cause gear rattle.

When the clutch engages spring force clamps the friction disc between the flywheel and the?

pressure plate
When the clutch is engaged, the disc is “squeezed” between the flywheel and pressure plate, and power from the engine is transmitted by the disc’s hub to the input shaft of the transmission. In layman’s terms, a pressure plate is a spring-loaded “clamp,” which is bolted to the flywheel.

Is a clutch damper necessary?

Why is dampening required within the clutch and flywheel system? Due to its inherent design, an automobile engine is subject to rotating fluctuations. Such fluctuations are caused by explosive combustion of the fuel and by imbalances in the crankshaft and other inertial components.

How are vibrations dampened by the clutch disc?

The damper springs in a clutch disc are used for vibration damping of the vehicle. Therefore, damper springs in the clutch are aimed to increase the comfort of the vehicle and protect the thermomechanical systems against the problems caused by vibration.

Why is my clutch making a knocking noise?

Steady knocking in the clutch area can be a loose flywheel or pressure plate, bad engine or transmission bearing, a broken transmission bearing, a broken transmission gear, or loose parts bouncing around in the clutch housing.

What is a likely cause of a vibrating clutch?

When your clutch pedal vibrates, that means the clutch disc is losing its grip on the flywheel intermittently. Possible causes of vibrating or chattering include: Clutch disc lining (friction material) worn out. Clutch disc lining burnt or contaminated with oil.

How to improve the performance of clutch systems and torsional dampers?

1Clutch systems and torsional dampers 16 Schaeļ¬„er SYMPOSIUM 2010 17 Clutch systems and torsional dampers1 1 In order to achieve better results with conven- tional damper technology, a shift in the drive train resonance would be helpful. The resonance frequency would have to be reduced for a DMF, and raised for an SMF.

What is the function of the damper on a car?

In this regard, damper technology also plays a key role for auto- matic transmissions, since the performance capability of the damper largely deter- mines the engine speed from which it is possible to drive with no slip and therefore optimal fuel consump- tion. LuK has already shown what is techni- cally possible today in that area.

How do tight engine and transmission boundary conditions affect the clutch?

Overall, tightened engine and transmission boundary conditions lead to higher require- ments on the clutch system (Figure 21). The engine-side excitement and the sensitivity of the transmission or the entire drive train in- crease.

How can I improve the performance of synchronous damper technology?

1 In order to achieve better results with conven- tional damper technology, a shift in the drive train resonance would be helpful. The resonance frequency would have to be reduced for a DMF, and raised for an SMF.
