1. The electro-hydraulic power steering system
The electric power steering (Electric Power Steering)
The electric power steering to provide power directly to the electric motor, power assist size-controlled by the electronic control unit (ECU) steering system. The torque sensor connected with the steering shaft when the steering shaft is rotated, the work of the sensor, signals to the ECU, ECU, the motor vehicle speed determined in accordance with the boosting effect, in order to ensure at low vehicle driving light, reliable high speed.
The electro-hydraulic power steering system
1 Main components: storage tanks, power steering control unit, the electric pump, steering gear, steering sensor, wherein the power a steering control unit and the electric pump is a unitary structure.
2 works: electro-hydraulic steering system overcomes the drawbacks of the conventional hydraulic power steering system. It uses the hydraulic pump is no longer directly driven by an engine belt, instead of using an electric pump, it is the status of all the work by the electronic control unit according to the traveling speed of the vehicle, steering angle, etc. ideal state calculated signal.
Briefly, large steering at low speeds, the electronic control unit drives the electronic hydraulic pump higher power output at a high speed, the driver turning the steering effort; car at high speeds, the hydraulic control unit drives the electro-hydraulic pump at a lower speed operation, high speed hit the steering does not affect the need to save part of the engine power. It is more commonly used power steering system.
