INTRODUCTION

Drive

train consists of Clutch, Transaxle and Drive shaft

CLUTCH –

The clutch is a single disc dry friction type with a diameter of 200 mm. It is of diaphragm

type and is mechanically actuated by a cable connecting clutch pedal and the clutch

release lever. No clutch pedal free play adjustment is required although clutch pedal

height from floor has to be adjusted as the clutch lining wears. The clutch pedal height

from the floor keeps on increasing as the clutch lining wears.

TRANSAXLE –

The vehicle has a transversely mounted engine and transaxle. This layout of engine is

typical of front wheel driven car. The gear box and differential are integrated into a single

housing termed as Transaxle. The drive is transmitted to front wheels from differential

side gears through constant velocity shafts.

The final reduction is done by a pair of helical gears. All the forward gears are

synchromesh (with first and second – double synchromesh and other gears single

synchromesh) and reverse gear is sliding mesh.

The gear shifting conforms to international H pattern, 5th and reverse being in line. All lay

shaft gears are free on it without needle bearings.

There is no pilot bearing for the input shaft and there are no control dimensions to be

maintained on input shaft and lay shaft. Pinion is integral with the Lay shaft and all the

gears on the Lay shaft are locked by circlips.

Speedo Sensor is located on differential housing.

DRIVESHAFT –

Driveshaft assemblies transmit engine power to independently suspended wheels. They

consist of an inner and outer constant velocity joint connected by an axle shaft. The inner

joint is completely flexible and can move in and out. The outer joint is also flexible, but

cannot move in and out.
