direction of play turning, parking, time and effort to turn around more easily.
1. The mechanical advantage of hydraulic power
· technology is mature, reliable, low cost, the size of the vehicle are applicable.
* are all mechanically connected, directly clear road feel.
2. Disadvantage mechanical hydraulic power
· need to rely on the engine power,The relative increase in energy consumption.
· To be replaced regularly to boost oil.
3. Mechanical technical principles of hydraulic power
Mechanical hydraulic power English referred to as the 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 a constant flow hydraulic power booster according to the different embodiment of the flow system.
Characteristics hydraulic pressure booster pressure-type hydraulic assist system is in a neutral position or whether the steering wheel position, the steering wheel is held stationary or in rotation, the fluid in the conduit system always maintained a high pressure state.
constant flow constant flow hydraulic power steering system, hydraulic steering pump, although always work, but when the hydraulic power system is not working, pump in the idling state, the load line than atmospheric Small, now most power steering systems use hydraulic flow constant.
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.
4. Mechanical hydraulic power related reading
mechanical hydraulic power was born in 1902, invented by the British FrederickW.Lanchester, and the first commercial application is postponed until half a century later. 1951 Chrysler applied to the hydraulic power steering system in a car on the Imperial system. Since the technology is mature, reliable, and low cost, it is widely popular after.
