INTRODUCTION TO TRANSMISSION SYSTEM :-  TYPES OF TRANSMISSION SYSTEM  CLUTCH  GEAR BOX  PROPEELER SHAFT  UNIVERSAL JOINTS  Final drive and differential  REAR AXLE Definition Of Transmission System :- The mechanism that transmits the power developed by the engine of automobile to the engine to the driving wheels is called the TRANSMISSION SYSTEM (or POWER TRAIN).It is composed of –  Clutch  The gear box  Propeller shaft  Universal joints  Rear axle  Wheel  Tyres Requirements Of Transmission System :-  Provide means of connection and disconnection of engine with rest of power train without shock and smoothly.  Provide a varied leverage between the engine and the drive wheels  Provide means to transfer power in opposite direction.  Enable power transmission at varied angles and varied lengths.  Enable speed reduction between engine and the drive wheels in the ratio of 5:1.  Enable diversion of power flow at right angles.  Provide means to drive the driving wheels at different speeds when required.  Bear the effect of torque reaction , driving thrust and braking effort effectively. The above requirements are fulfilled by the following main units of transmission system :-  Clutch  Gear Box  Transfer Case  Propeller Shaft and Universal Joints.  Final Drive  Differential  Torque Tube  Road Wheel Difference between tyre and wheel :- Wheel Tyre A wheel is a device that allows While tyre is the outer part of heavy objects to be moved easily the wheel made up with rubber through rotating on an axle and mostly use in vehicles for through its centre, facilitating smooth movement movement or transportation while supporting a load (mass),or performing labor in machine. Types Of Transmission System -: Hydraulic transmission system:- Fluid coupling -: A fluid coupling is a hydrodynamic d
