STUDY OF THREE WHEELER CHASSIS FRAME AND POWER TRANSMISSION SYSTEM.


 STUDY OF THREE WHEELER CHASSIS FRAME AND                                                        POWER TRANSMISSION SYSTEM.
AIM :

            To study the various features and measure the various dimension of the chassis frame of three wheeler and power transmission system.

TOOLS REQUIRED :

            Measuring tape.

PROCEDURE :

            Using the measuring tape, note that
Wheelbase:     It is the distance between the centre points of front wheel to the centre point of rear wheel.
Wheel track:  It is the distance between the centre points of two rear wheels.       
Over all length: It is the through out distance between front side to the vehicle.   
Over all width: It is the distance taken from top portion of the vehicle to the ground level.
Ground clearance: It is the distance taken between nearest part or portion towards ground          level. (ex: differential)

POWER TRANSMISSION SYSTEM :

            The system by which the power from engine is transmitted to the wheels is called transmission system. Transmission system carries engine power to the rear wheel. Power at the rear wheels move the vehicle forward overcoming external forces. Clutch is located between the engine and gearbox. Clutch transmits engine power to the gearbox. In Three-wheeler, multiple clutches is used. When the clutch is in the disengaged position, the power transfer is interrupted. Such power interruption will enable shifting of gears smoothly with out damaging gear teeth. Gearbox provides different torque at the rear wheel according to the requirements by engaging different gear combination.

PROPELLER SHAFT DRIVE :

            This system is mostly used in three-wheeler. Like four wheelers, the propeller shaft in this system also consists of a sliding joint at one end and universal joints at both the ends.

RESULT :

            Thus the various features of the chassis are studied & its dimensions have been measured and the power transmission system also studied.
