POWER STEERING

POWER STEERING:
Power steering assists the driver of an automobile in
steering by directing a portion of the vehicle’s power to
traverse the axis of one or more of the road wheels. As
vehicles have become heavier and switched to front wheel
drive, particularly using negative offset geometry, along with
increases in tire width and diameter, the effort needed to
turn the steering wheel manually has increased often to the
point where major physical exertion is required. To alleviate
this, auto makers have developed power steering systems:
or more correctly power-assisted steering on road going
vehicles there has to be a mechanical linkage as a fail safe.
There are two types of power steering systems hydraulic
and electric/electronic.
