7.1 INTRODUCTION
In any motor cars and other four and six wheeler vehicles, steering is main component.
Properly designed steering, works well and guides the vehicle to move in correct direction. Mainly steering is linked to the front axel with gear train mechanism. On the front axle, wheels are mounted, and with the help of steering wheel, the driver can turn the vehicle in right, left or straight directions.
The function of steering mechanism is clearly explained in this unit. In this unit, we also elaborated on the front axel and its types.
Principle of steering, steering geometry, steering gearbox and working of steering systems have been clearly explained.
Objectives
After studying this unit, you should be able to
understand about front axel and steering,
define function of front axle and steering,
explain the principle of steering mechanism,
describe the linking mechanism of front axle and steering wheel, and
understand the steering geometry.

7.2 FRONT AXLE
Front wheels of the vehicle are mounted on front axles. Functions of front axle are listed below :
(a)
It supports the weight of front part of the vehicle.
(b)
It facilitates steering.
(c)
It absorbs shocks which are transmitted due to road surface irregularities.
(d)
It absorbs torque applied on it due to braking of vehicle.
Construction and Operation
Front axle is made of I-section in the middle
