What is Transmission System (Clutch and Gear Box) in automobile?

           

             
                  The power developed by the engine is transferred to the wheels by transmission system. Transmission system must do three jobs :

(a) It must provide varying gear ratios. Number of gear ratios are equal to number of gears in a vehicle. 

(b) It must provide a reverse gear for moving vehicle in reverse direction. 

(c) It must provide a neutral or disconnecting arrangement so that the engine can be uncoupled from the wheels of the vehicle. In a conventional transmission system, there is a clutch, a manually operated transmission (gear box), a propeller shaft and a differential or final drive.
