Answer the following discussion questions:

1. List the basic parts of an automotive clutch.

2. Explain the operation of a clutch.

Read the chapter summary below:

■ An automotive clutch is used to connect and disconnect the engine and manual (hand-shifted) transmission or transaxle.

■ A wet clutch does not slip and is more energy efficient than a fluid coupling or torque converter.

■ The major parts of an automotive clutch include the clutch release mechanism, clutch fork, release bearing, pressure plate, clutch disc, flywheel, and pilot bearing.

■ When the driver presses the clutch pedal, the clutch disc is released from the flywheel. When the clutch pedal is released by the driver, the input of the flywheel, disc, pressure plate, and transmission are locked together.

■ The clutch housing, sometimes called a bell housing, bolts to the rear of the engine, enclosing the clutch assembly.

■ An automatic manual clutch requires the driver to press electric steering wheel-mounted shift buttons to change gears manually.

■ In a dual-clutch transmission, one clutch disengages as the other clutch engages without an interruption of power flow.

■ The clutch in a hybrid vehicle is a device for connecting and disconnecting crankshaft torque from the transmission or transaxle and motor-generator.

■ A hybrid vehicle with a wet clutch uses two wet clutches to control power flow into and out of the motor-generator.
