What is the purpose of a clutch damper?

What is the purpose of a clutch damper?

To prevent such noise, the NVH is absorbed by a clutch damper function which suppresses the movement of the free, spinning gears and attenuates the vibration transmitted to the transmission. The clutch damper function is provided by a series of springs located between the flywheel and the transmission.

How vibrations are dampened by the clutch disc?

The mechanical vibrational energy attains another form by damping and changes in amplitude over time. The damper springs in a clutch disc are used for vibration damping of the vehicle.

What is torsional damper?

Torsional dampers are placed behind the engine as vibrational dampers when the powertrain does not include a separating and starting clutch. Nearly every commercial vehicle with a powershift transmission or hydrostatic drive has a torsional damper that ensures “peace and quiet” in the vehicle.

What is a clutch disc?

Clutch Discs The clutch disc is a rounded plate used to connect the engine of a vehicle to the transmissions input shaft allowing the temporary separation needed to shift gears.

What is clutch disc damper?

The torsional damper integrated in the clutch disc is the main element for adjusting torsional rotation properties throughout the powertrain, from the combustion engine to the wheels. This effective vibrational damping system consists of a friction unit and spring sets for both driving and idling.

What is a clutch accumulator?

Accumulators rely on the action of a piston or a valve to delay the delivery of high pressure to a clutch or band. An accumulator works like a shock absorber and cushions the application of servos and disc packs.

How can I check the clearance of my Clutch?

Some manufacturers provide a specification for the clearance between the clutch disc tang and the basket fingers. This clearance can be measured by temporarily installing a clutch disc into the basket and using a set of lash gauges to check the clearance between the two parts.

How to tell if clutch basket dampers have worn?

The easiest way to determine if the dampers have worn is by trying to rotate the clutch gear independently from the clutch basket. Depending on how worn the dampers are this may take a little bit of force, so it is best to lock out the clutch gear and primary drive gear.

Why are my clutch dampers cracking and cracking?

The dampers may also show signs of cracking and other damage. Next, you’ll want to determine what bolts to use to secure the gear and backing plate back onto the clutch when it comes time to reassemble the clutch basket.

How to know if your clutch disc is bad?

Check for oil and coolant leaks around the back of the engine. Look for signs of oil or coolant coming out of the bottom of the clutch housing. Check clutch disc wear using CLUTCH-03. Replace clutch disc if there are signs of contamination or if the wear check is bad (CLUTCH-01). Pressure plate or flywheel warped.

How does the exedy clutch damper assembly work?

https://www.exedyusa.com/ | This video explains how a clutch damper assembly works to dampen engine vibrations. EXEDY first developed this style disc back in 1980 when we were still known as Daikin Clutch. Loading…

What’s the best way to test a clutch?

Alternatively, get to highway speed in your highest gear and floor it. If the RPMs shoot up, you’ve got slippage. There are two already great answers to this, but for future readers: Put the vehicle in to forth gear, as you release the clutch give it gas as if it was a normal take off. If the vehicle stalls, chances are the clutch is still good.

When do you know your clutch is slipping?

If you come from a flat surface, onto the hill, and your RPMs begin to climb in order to maintain speed (with bad slippage you’ll begin to lose speed either way depending on the angle of the hill), then your clutch is slipping. From a Stop: You can test your clutch this way, the same way you would the 4th Gear Test above, with two exceptions.

Can you do a 4th gear clutch test?

The 4th-gear test has the drawback that it is difficult to check for slip at that RPM and full throttle, plus this puts enormous wear on the clutch, plus you’ll only find out if there is much slip, but not little or none.
