WHAT IS TRANSMISSION..?
A mechanical power transmitting system,
which provides controlled application of
power.

USE OF TRANSMISSION:-
PROVIDES DIFFERENT VALUES OF POWER,
ACCELERATION AND TORQUE FORDIFFERENT GEAR RATIOS.

SEMIAUTOMATIC TRANSMISSION:-
Gear shifting takes place without pressing c
Changes gear on command of driver througelectronic sensors.

GEAR SHIFTING TAKES PLACE AUTOM
THROUGH ELECTRONIC SENSORS.
AUTOMATIC TRANSMISSION:

CLUTCH:
Clutch is a mechanical device that
provides for the transmission of
power from one component to
another (the driven member) when
engaged, but can be disengaged.

1. MULTIPLE PLATE CLUTCH:
THIS TYPE OF CLUTCH HAS SEVERAL D
MEMBERS INTERLEAVED OR "STACKED WITH SDRIVEN MEMBERS.
A FEW TYPES OF CLUTCH

2. WET CLUTCH
A wet clutch is immersed in a cooling
lubricating fluid that also keeps
surfaces clean and provides smootherperformance and longer life.
Wet clutches, however, tend to lose
some energy to the liquid.

3. CENTRIFUGAL
This clutch system employs centrifugal force to
automatically engage the clutch when the engine
rises above a threshold and to automatically disenthe clutch when the engine rpm falls low enough.

4 CONICAL
The cone's taper means that a given amount of
movement of the actuator makes the surfaces
approach (or recede) much more slowly than inclutch. As well, a given amount of actuating forc
creates more pressure on the mating surfaces

5. TORQUE LIMITER
Also known as a slip clutch or safety clutch, thi
device allows a rotating shaft to slip when highthan normal resistance is encountered on amachine
