The transmission of power from Engine to the Rear Wheels through a number of devices so such system is called as the Transmission system. The transmission system is particularly related to the Buses so it is named as the Transmission system in Buses. This ppt stuffed with types, Working and advantages.

2. INTRODUCTION
• Transmission system is one of the systems in the
automobiles.
• It is used to transmit power and torque from the
engine to the driving wheels.
• It consists of Clutch, Gear box, Propeller shaft,
Differential, Axles and the driving wheels.

4. DEVICES IN TRANSMISSION
SYSTEM
There are different types of devices in
transmission system of automobile.They are
• Clutch.
• Gearbox.
• Propeller shaft.
• Differential.
• Axles and driving wheels

5. CLUTCH
A Clutch is a device which is used to engage and
disengage the driving and pinion shafts.
There are two types of clutches. They are
1.Three finger clutch.
2.Four finger clutch.

6. Clutch system

7. Three Finger Clutch
• The three fingered clutch is also an " PUSH ". In this
type of Clutch there will be only " THREE FINGERS "
and the total tension is taken by the three fingers while in
the engage and disengage operations.
• This is a hard type of Clutch for operate due to the less
fingers. Its spring tension is of appropriately 71 to 74 N-
M.

8. Four Finger Clutch
• The four fingered clutch is a " PUSH " type clutch.
In this type of Clutch there will be " FOUR
FINGERS " and the total tension is taken by the four
fingers while in the engage and disengage operations.
• The tension in the springs will be around 71 to 74 N-
M.

10. GEAR BOX
Gear box provides speed and torque conversions
from a rotating power source to another device using
the different gear ratios.
Types of gear boxes
1. Constant mesh and
2. Synchromesh gear box.

11. Constant Mesh Gear Box
• Example of constant mesh gear box is GB-13.

12. Synchromesh Gear Box
• Example of synchromesh gear box.

13. PROPELLER SHAFT
Propeller shaft is a shaft which transmits the power and
torque from the gear box to the differential.

14. DIFFERENTIAL
Differential helps to
transmit the power or
torque from the propeller
shaft the driven wheels and
it is used to transmit the
amount of torque or power
equally to both the wheels.

15. DRIVING WHEELS
Wheel drives are the rear
wheels where the movement
of the vehicle takes place by
the all devices, the rear
wheels are the end of the
transmission of the power and
tyres are connected to it.

16. RESULT & DISCUSSION
• The type of Gear box and Clutch is to be used is depends
upon the type of the engine used in the vehicle.
• There will be different types of Gear boxes and Clutches to
the different buses but the propellers used and differential
used is remains same for the maximum conditions of the
buses.
• The components which assembles in the device are very
heavy because they must bear heavy loads and the tension.

17. CONCLUSION
Assembly of constant mesh gear box, Synchromesh
gear box, universal joint, Drive shaft, Differential.
Working and function of the above mentioned
components of an automobile have been observed.
Reusing and efficient usage of automobile
components have been studied.
