Abstract - In automobiles Clutch is one of the most essential components. It is located between the gear box and the engine. It is also used in the transmission system of a vehicle to disengage and engage the transmission system from the engine. The most important function of the clutch is to initiate the motion and increase the velocity of the vehicle by transferring kinetic energy from the engine flywheel. It works on the principle of friction. Especially, for their durability and compactness the precise prediction technique of maximum structural stress should be requested in design of mechanical clutches. In this the study of a simple transmission system consisting of engine, clutch, gearbox and load is designed for the load lifting application.

1. INTRODUCTION
1.1.2.1 SINGLE PLATE OR DISC CLUTCH
The clutches are designed to transfer maximum torque with minimum heat generation. The wheels should be disconnected from the engine in order to stop the vehicle without stopping the engine, which facilitates through clutch, which is a mechanism for transmitting rotation which can be engaged and disengaged. It has been seen that internal combustion engine, does not produce high power at low speed. So that the engine must be rotating at a speed at which sufficient power is developed, before the drive to the wheels to be established. The clutches used must allow the drive to be taken up smoothly so that the vehicle can be gradually moved away from the stationary position. Once the drive is moving, it will be necessary to change gear and so disengagement of the engine or transmission is required. These two duties can be performed by various mechanical or other mechanisms or the friction system is considered, which a mechanical type of mechanism.
Fig -1: SINGLE PLATE OR DISC CLUTCH Single plate clutch consists of a clutch plate whose both sides are lined or faced with friction material usually feredo. It is mounted on a hub which is free to move axially along splines or key way on the driven shaft. Pressure plate is mounted inside the clutch body which is bolted to flywheel. Both pressure plate and flywheel rotate with engine. Pressure plate pushes clutch plate towards flywheel by a set of strong springs arranged radially inside body. Three levers called release levers or fingers are carried on pivots suspended from the case of body. Levers are arranged such that pressure plate moves away from flywheel by inward movement of thrust bearing. Thrust bearing is
1.1 FRICTIONAL CLUTCHES Frictional clutch has its principal applications in transmission of power of shafts and machines which must be started or stopped frequently. In cases where power is to be delivered to machines partially or fully loaded. In automobiles to connect engine to the driven shaft

Contact surfaces should develop a frictional force that may pick up and hold the load with reasonably low pressure between contact surfaces. Heat of friction should be rapidly dissipated and tendency to grab should be minimum. Surfaces should be backed by a material soft enough to ensure reasonably uniform distribution of pressure.
