Electronic hydraulic power steering system
1. Main components: storage tanks, power steering control unit, the electric pump, steering gear, steering sensor, wherein the control unit and the electric power steering pump is a unitary structure.
2. Working principle: electro-hydraulic steering system overcomes the drawbacks of 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 electronic control unit drives a hydraulic pump at a lower speed operation does not affect the need to play a high-speed turn at the same time, saving part of the engine power. It is more commonly used power steering system.
