direction of play turning, parking, time and effort to turn around more easily.
1. The hydraulic power electronic advantage
* of the engine does not directly driven oil pump, driven by a motor, the energy consumption relative to the engine is reduced.
* The vehicle speed booster size can be adjusted, fast response, more humane.
2. Disadvantage electronic hydraulic power
Electronic components more, relatively high maintenance costs.
· late still need maintenance.
3. The technical principle of electro-hydraulic power
Electronic English referred to as hydraulic power EHPS, i.e. ElectroHydraulicPowerSteering. The system of the steering pump is no longer directly driven by the engine, but rather is driven by an electric motor, and the installation of the electronic control system on the basis of the previous, such that the magnitude of the steering assist force is not only related to the steering angle, is also associated with the vehicle speed.
increasing the hydraulic reaction apparatus and liquid dispensing valve
Mechanical structures, the new electronic control system includes a vehicle speed sensor, solenoid valve, the steering ECU and the like. Works with mechanical hydraulic power is basically the same, except that the oil pump is driven by an electric motor, while efforts to boost variable. After monitoring vehicle speed sensor, the electronic control unit acquires data of the steering control valve opening degree is changed by controlling the oil pressure, steering efforts to achieve size adjustment.
