WHAT IS TRANSMISSION..?

A mechanical power transmitting system,

which provides controlled application of

power.


11/28

USE OF TRANSMISSION:-

PROVIDES DIFFERENT VALUES OF POWER,

ACCELERATION AND TORQUE FORDIFFERENT GEAR RATIOS.

TYPES OF TRANSMISSION:

Z speed transmission Constantly vTransm

1. Sliding Mesh

2. Constant Mess 1.Pulley Transm

3. Synchromesh 2.Torsion Trans4. Semi automatic 3.Hydrostatic

5. Automatic

6. Twin clutch

SYNCHROMESH TRANSMISSION:-


14/28

SEMIAUTOMATIC TRANSMISSION:-

Gear shifting takes place without pressing c

Changes gear on command of driver througelectronic sensors.


15/28

GEAR SHIFTING TAKES PLACE AUTOM

THROUGH ELECTRONIC SENSORS.

AUTOMATIC TRANSMISSION:

No comman

from driver f

shifting

CLUTCH


20/28

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.


21/28

1. MULTIPLE PLATE CLUTCH:

THIS TYPE OF CLUTCH HAS SEVERAL D

MEMBERS INTERLEAVED OR "STACKED WITH SDRIVEN MEMBERS.

A FEW TYPES OF CLUTCH


22/28

MULTI-PLATE CLUTCH


23/28

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.


24/28

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.


25/28

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


26/28

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
