Hydraulic Power Steering

Conventional hydraulic steering system has the problems of "low-speed heavy, high-speed flight" and energy-wasting when steering, the main reason is after the system is designed, the power characteristics are fixed. To solve this problem it is necessary to achieve the power characteristics of changing power steering system according to speed of vehicles, in order to offer the power that matches the speed. Using vehicle speed sensor signal to control pilot solenoid unloading valve to regulate the pressure of hydraulic system, can achieve the regulation of power characteristics, this article is based on such idea to design variable hydraulic power steering system for hydraulic power steering system of light trucks.

This paper discusses the configuration and the action principle of a new variable displacement of double-action vane pump, which consists of floating blocks. The floating blocks that may move up and down in accordance with the rotational speed of the pump. The pump belongs to an automotive hydraulic power steering system, and prosperous utilization is expected. The theoretical flow model of the new pump was established and the pump flow changes under different speed were compared.
