Gearbox ».
The gearbox is placed between the clutch and the propeller shaft. The
principal function of the gearbox is to vary the speed of the car movement
to meet the road conditions. The gearbox provides four forward speeds and
one reverse, as follows:
 first or low gear
 second gear
 third gear
 fourth or top gear
 reverse gear
There are many constructional arrangements of gearboxes, which can be
classified as follows: sliding – mesh type
 constant – mesh type
 epicyclical (planetary) type
The sliding - mesh type is the simplest one and is the oldest historically.
The constant- mesh type is the most widely used type. They are termed
“ordinary” gearing, the characteristic feature of which is that the axes of
the various gears are fixed axes. The gears simply rotate about their own
axes.
The characteristic feature of epicyclical (planetary) gearing is that one
gear rotates about its own axis and also rotates bodily about some other
axis.
To secure the several speeds of the car the clutch shaft is mounted in
direct line with the gearbox shaft. The gearbox shaft carries on it the
sliding gears which are used for shifting to secure the forward speeds and
the reverse drive.
