The high-pressure tube from turning ZhuLiBeng out pipe, and received steering machine, then low-pressure return hose is through the front oil tanks, or move on to cooling tubing then return to the tank, again from steering oil tank into a ZhuLiBeng flow.

   Tube to the actual structure is not identical also, hose by layers of curtain layer or woven wire layer, and low pressure pipe is likely a layer of woven layer, mainly based on the design of the system pressure, the Chrysler platinum sharpness of high-pressure tube car 10Mpa, low pressure pipe pressure requirements are just for 1Mpa pressure

   Using mechanical steering device can achieve automotive steering, when steering shaft load is bigger, only by driver's physical as steering energy it's hard to smooth the steering. Power steering system is in mechanical steering system based on a set of steering device is described.compare strength formed. Steering strength device lightened the pilot control steering dish reaction. Steering energy comes from the driver's physical and engines (or motor), among the engine (or motor) occupied the main part, by turning stronger device provide. Under normal circumstances, the driver can easily control the steering. But in steering strength device failure, returned to mechanical steering system state, generally by the driver can independently bear automotive steering task.

(1)         the hydraulic power steering system. Which belongs to the steering strength device's parts are: steering pump 7, 8, steering tank steering tubing and located in single-piece redirector 4 6 steering control valves and steering internal power cylinder 5, etc. When pilots turning steering disk 1, by mechanical steering the steering levers of 9 moving, and the drive steering knuckle arm, the steering wheel, which changes the deflection car driving direction. Meanwhile, steering input shaft is driven steering gear steering control valve internal rotation of steering power cylinder produce hydraulic force, help the driver turned to operate. Because have turned to strength device driver than action, only by mechanical steering system when the much smaller steering moment, can make the steering wheel deflection.

   Disadvantages: high energy, especially at low speed when turning, feel direction compared to sink, engine is also sweat. Also, because of hydraulic pressure, easier to damage booster.

(2) electric Power Power Steering system, the abbreviation over-bed EPS or EPS (Electronic Power Steering system) in mechanical Steering mechanism of basis, increase signal sensors, the Electronic control unit and Steering mechanism.

   Over-bed EPS is using motor as a power source, according to the speed and steering factors such as parameters, the electronic control unit complete power control, its principle can be summarized as follows: when manipulating steering sets, packed in steering dish shaft torque sensor constantly measured on steering shaft torque signal, this signal and speed signal input at the same time to the electronic control unit. Electronic control units according to these input signal, determine the booster torque, namely the magnitude and the direction of current and rotational selected motor direction, adjust the size of the auxiliary power steering. Motor torque by electromagnetic clutch through deceleration institutions deceleration increase torque later add in automotive steering mechanism, to get a car condition and adapt to the steering reaction. For example, the fox EHPAS electronic hydraulic system by

Disadvantages: low energy consumption, sensitive and electronic unit control, save engine power, power play more ideal.
