PRINCIPLES OF POWER STEERING:-
Power steering is one type of hydraulic device for
utilizing engine power to reduce steering effort. Consequently, the engine is used to drive a pump to develop fluid pressure, and this pressure acts on a piston within the gear box so that the piston assists the sector shaft effort. The amount of this assistance depends on the extent of pressure acting on the piston. Therefore, if more steering force is required, the pressure must be raised. The variation in the fluid pressure is accomplished by a control valve which is linked to the intermediate shaft and the steering main shaft.
Steering system components:-
Steering wheel, column and shaft – driver inputs
Steering gear – changes direction – rotating steering wheel into linear motion
Steering linkage – connects steering gear to steering arms
Ball joints – allows movement of steering components and suspension
Steering Wheel:-
Steering Wheel attach to steering column and shaft by 1 or more fasteners,most single nut .It have an interference fit on the shaft &very tight fit, may need a puller . it may contain an airbag assembly , radio controls , cruise controls.
Steering Column:
Steering ColumnContains and supports the steering shaft& may have a tilt mechanism. It may be designed to collapse during front impact & has plastic or soft metal rivets that are easily damaged or broken from improper use or removal.
