The clutch has several friction plates. The friction clutch basically consists of four major parts

Friction plate carefully crafted Vios clutch has several friction plates friction clutch basically consists of which four major parts:

1. What are the basic components of the friction clutch?

The friction disc clutch is basically composed of an active part, a driven part, a compression mechanism and an operating mechanism.

1. Active part: flywheel, clutch cover (not clutch housing), pressure plate;

2. Driven part: driven disk assembly with torsion shock absorber (driven wheel hub, driven disk body, friction plate);

3. Compression part :16 circular coil springs; The clutch has several friction plates.

4. Operating mechanism: disengaging sleeve and disengaging fork (located inside the clutch) < How the friction plate of the clutch works.

The engine flywheel is the active part of the clutch. The driven disc with friction plate and the driven wheel hub are connected to the driven shaft (i.e. the drive shaft of the transmission). The compression spring presses the driven disc against the flywheel end face. The composition of friction disc clutch.

Engine torque is transmitted to the driven disc via friction between the flywheel and the contact surface of the driven disc, and then to the drive wheel via a series of components of the driven shaft and drivetrain. The greater the spring pressure, the greater the torque transmitted by the clutch.

Since the car often needs to maintain power transmission during driving, and the interruption of transmission is only a temporary need, the active and driven parts of the clutch are often in a engaged state.

The friction pair uses a spring compression device to meet this requirement. When you want the clutch to disengage, as long as you step on the pedal in the clutch operating mechanism, the fork set in the hub ring slot of the driven disc will push the driven disc to overcome the pressure of the compression spring to move in the direction of loosening, and separate from the flywheel, and the friction will disappear, thus disrupting the transmission of power.

When the power transmission needs to be restored, in order to stabilize the changes in the speed of the car and the engine speed, the recovery speed of the clutch pedal should be properly controlled, so that the driven disc can recover contact with the flywheel under the action of the compression spring pressure. The pressure between the two contact surfaces increases gradually, and the corresponding friction torque also increases gradually.

When the flywheel and the driven disk are not tightly connected, the friction torque between the two is relatively small, and the two can rotate out of sync, that is, the clutch is in a slippery state. As the flywheel and driven disk connection tightness gradually increased, the speed gradually equal. Until the clutch is fully connected and stops slipping, the speed of the car is proportional to the speed of the engine.

The maximum torque of the friction clutch depends on the maximum static friction torque between the friction surfaces, which depends on the maximum pressure between the friction surfaces and the size and nature of the friction surface. Therefore, for a clutch with a certain structure, the static friction torque is a fixed value, and when the input torque reaches this value, the clutch slips, limiting the torque of the transmission system and preventing overload.
