DRIVETRAIN

Drive train consists of Clutch, Transaxle andDrive shaft.

CLUTCH

The clutch in the TATA NANO is a

Single Plate Dry

Friction Diaphragm

type. It is mechanically actuated

by a cable connecting clutch pedal and the clutch

release lever.

The diaphragmspring in the clutch cover is of a tapering

finger type, which is a

solid ring

in the outside, with a

series of tapered fingers pointing inward.

The clutch disc, carrying

six torsional coil springs,

is positioned on the transmission input shaft with an

involute spine fit.

The clutch cover is secured to the flywheel, and carries

the diaphragm spring in such a way that when the

clutch release bearing is held back the peripheral edge

of the spring pushes on the pressure plate against the

flywheel (with the disc in between). This is the engaged

condition of the clutch.

Depressing the clutch pedal causes the release

bearing to advance and pushes on the tips of the

tapered fingers of the diaphragm spring. When this

happens, the diaphragmspring pulls the pressure plate

away from the flywheel, thereby interrupting the flow

of drive from flywheel through clutch disc to

transmission input shaft.

TRANSAXLE

The TATANano has a Transaxle TA-59 which is at the

rear of the vehicle along with the engine. The transaxle

has the shortest possible distance between the lay

shaft axis and input shaft axis (centre distance).

All the forward gears are synchromesh and the reverse

gear is sliding mesh.

The Vehicle speed is detected with a help of electronic

sensor which is fitted on the Differential of the

Transaxle.

The Gears are shifted with help of Push pull cables.

These Cables ensure that there is negligible vibration

transmitted to the Gear lever, making gear shifting a

delightful experience.

DRIVESHAFT

Driveshaft are flexible assemblies, which transmits

engine power to independently suspended wheels.

They consist of an inner and outer constant velocity

joint connected by an axle shaft. Both inner and outer

joints are completely flexible and can move in and

out.
