ABSTRACT
The clutch is an essential component of the manual automotive transmission system. It is the system used to engage or disengage the engine from the rest of the transmission system. When the clutch is engaged, the engine is connected to the transmission, and power flows from engine to the rear wheels through the transmission system. There are various factors associated with the effectiveness of the clutch, such as coefficient of friction, effective diameters, etc., which affect transmission efficiency. These parameters are discussed in detail in this chapter. The working principle, basic requirements, construction and working, operating mechanisms and design aspects of the clutch are also presented.
