Abstract

A system for correcting the steering performance of a commercial vehicle comprises a steering booster pump, a steering gear box, an oil storage tank and a monitoring part. A pressure reduction oil passage is arranged between the steering booster pump and the steering gear box, and a heat dissipation oil passage is arranged between the steering gear box and the oil storage tank; the monitoring partcomprises a single-chip microcomputer, the single-chip microcomputer is in circuit connection with a pressure sensor, a flow sensor, a temperature sensor, three one-way electromagnetic valves, a control switch and an alarm, the pressure sensor and the flow sensor are installed on an oil inlet of a first three-way valve, the temperature sensor is installed in the oil storage tank, the first one-way electromagnetic valve is installed on an oil return port of the first three-way valve, and the second one-way electromagnetic valve and the third one-way electromagnetic valve are installed on two oil outlets of a second three-way valve respectively; the pressure reduction oil passage has a pressure reduction effect on hydraulic oil, the heat dissipation oil passage has a rapid heat dissipationeffect on the hydraulic oil, and the monitoring part can automatically monitor the hydraulic oil and correct the steering performance in real time. By using the system, the controllability of vehicle's frequent steering and the driving safety are improved.

Description

technical field [0001] The invention belongs to the field of automobile steering systems, in particular to a system for correcting the steering performance of commercial vehicles. Background technique [0002] A car booster pump refers to a component that contributes to car performance improvement and stability. Steering assist is mainly to assist the driver to adjust the direction of the car, and to reduce the force of steering wheel for the driver. Power steering also plays a certain role in the safety and economy of driving. In the existing market, power steering systems can be roughly divided into three categories: mechanical hydraulic power steering systems, electronic hydraulic power steering systems and electric power steering systems. At present, commercial vehicles generally adopt mechanical hydraulic power steering system. The system is mainly composed of steering resistance pump 1, steering machine 2, oil storage tank 3 and other components, such as figure 1 A...
