In order to transmit the power of the engine to the road wheels of an automobile, a drivetrain is normally equipped. Although the details of the drivetrain vary widely in different types of automobiles, the general principle are the same in all cases.
1.1.1 Flywheel
The flywheel provides a base for the starter ring gear, and also forms the foundation on which the other clutch parts are attached.
The surface of the flywheel that mates with the clutch disc is machined smoothly.
For the clutch to work property, the flywheel must be perpendicular to the cranksΒιβλιοθήκη Baiduaft with very little allowable runout.
1.1.2 Clutch Disc
The clutch disc (or driven disc) contains a circular metal plate attached to a reinforced splined hub.
1.1.5 Double Clutch
A double clutch is a driving procedure primarily used for automobile with an unsynchronized manual transmission.
The double clutching technique involves the following steps： 1. The throttle (accelerator) is released, and the clutch pedal is pressed, and the gearbox is shifted into neutral.
1.1.4 Clutch Linkage
Engagement and disengagement of the clutch assembly are controlled by a foot pedal and linkage that must be properly adjusted and relatively easy to apply. The clutch linkage connects the clutch pedal to the clutch fork. The clutch fork and linkage provide the means of converting the up-and-down movement of the clutch pedal into the back-and-forth movement of the clutch release bearing assembly.
1.1.3 Cover Assembly
The clutch cover assembly contains the pressure plate, springs, and other parts according to the design of the clutch. The cover is bolted to the flywheel and rotates with it at the speed of the crankshaft. The clutch cover assembly smooth on the side facing the engine and driven disc (or discs) and is itself driven by pins or lugs on the clutch cover.
The major parts of the clutch include the flywheel, clutch disc, cover assembly, pressure plate, release bearing, and clutch linkage. Other parts which make up the clutch assembly are the transmission input shaft and the clutch housing.
1.1 Clutch
The clutch is a device to engage and disengage power from the engine, allowing the vehicle to stop and start.

Normally the hub is mounted on coil springs to provide cushion engagements. The clutch disc operates in conjunction with a pressure plate or a clutch cover.
