Added NOTE: The mechanical unpowered steering effort is very heavy. Driving the car without power to the steering should be used only to guide the car to a safe place to stop. Attempting to turn the steering wheel without power when the car is not moving may break the steering wheel. [7]
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
DSR assists the driver by determining the correct steering ratio in a vehicle's power steering system to provide steering corrections to stabilize vehicles and increase safety. The system determines the steering ratio (the amount of turning of the steering wheel to the amount of turning of the vehicle’s wheels) based on factors such as ...
By inclining the steering axis inward (away from the wheel), it causes the spindle to rise and fall as the wheels are turned in one direction or the other. Because the tire cannot be forced into the ground as the spindle travels in an arc, the tire/wheel assembly raises the suspension and thus causes the tire/wheel assembly to seek the low ...
A Hydraulic Power Steering (HPS) uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. Electric Power Steering (EPS) is more efficient than hydraulic power-steering, since the electric power-steering motor only needs to provide assistance when the steering wheel is turned, whereas the ...
A lower steering ratio means that the steering wheel is turned less to get the wheels turning, but it will be harder to turn the steering wheel. Larger and heavier vehicles will often have a higher steering ratio, which will make the steering wheel easier to turn. If a truck had a low steering ratio, it would be very hard to turn the steering ...
The free rotation is intended to help make steering with one hand easier or faster. Some heavy automobiles without a power steering system tended to have heavy and slow responses requiring hand-over-hand turning of the wheel by the driver, and the knob allowed the driver to "crank" the steering wheel to make faster turns.

Turning the steering wheel displaced the bogies to the left or right inducing a modest turn. Further turning of the wheel engaged braking on one side or the other. The Light Tank Mk VII Tetrarch used a similar system but the front wheels and two middle wheels on either side pivoted to induce the warp. [7]
