A New Hydraulic Power Steering System for Hybrid City Bus

Abstract:

A new type power steering system was developed for electric hybrid city bus. It is mainly composed of fluid reservoir, electric motor, steering pump, safety valve, solenoid, pressure sensor, hydraulic cylinder, braking air tank, controller, steering wheel, steering angle sensor, steering control valve, mechanical steering mechanism, steering power cylinder. Its main idea is based on using of pressure from braking air tank to push a cylinder to generate hydraulic pressure. It can provide enough pressure for steering needing timely. And the steering pump does not need working at the time of no steering requirement. The application of a new type power steering system can save energy to improve fuel efficiency.
