Technology Principle
Mechanical hydraulic power English referred to as HPS. The main component of the hydraulic pump, tubing, a pressure fluid control valve, V-belts, storage tanks and the like. This embodiment is part of the engine power output is converted into hydraulic power pressure, a force is applied to the steering assist system, thereby steering the tire wheel.
can be divided into hydraulic pressure and power flow in the system depending on the mode ofConstant flow hydraulic booster.
hydraulic pressure booster
Characteristics of hydraulic pressure power steering system is in a neutral position or whether the steering position, the steering wheel is held stationary or in rotation, the fluid in the conduit system always maintained a high pressure state.
A constant flow hydraulic power
constant flow hydraulic power steering pump, although a steering system is always working, but hydraulic power system is not working, pump in the idling state, the load line than that pressure-type small, and now most of the hydraulic power steering systems use the constant flow.
It can be seen Either way, the steering pump are essential components, which can be input mechanical energy into the engine oil pressure is. This is why virtually mechanical hydraulic power consumption increases.

Mechanical hydraulic power was born in 1902, invented by Englishman Frederick W. Lanchester, the first commercial application is postponed until half a century later.
1951 Chrysler applied to a hydraulic power steering system in a vehicle based on Imperial. Since the technology is mature, reliable, and low cost, it is widely popular after.
