Test bed for steering system of electro-hydraulic servo automobile

Abstract

The invention discloses a test bed for a steering system of an electro-hydraulic servo automobile. The test bed comprises a testing machine main body, an electro-hydraulic servo control system and a power pump station which provides hydraulic power for the testing machine main body, wherein the testing machine main body comprises a steering torque loading device, a steering device to be detected, a steering torque output device and an axle fixed mount; and both the steering torque loading device and the steering torque output device are provided with a hydraulic servo driving device and a parameter detection device which are in signal connection with the electro-hydraulic servo control system. The test bed has the beneficial effects that: the entire steering system of the automobile can be comprehensively tested in a test room, various test conditions of a real automobile test are completely imitated, the time and labor are saved, and the detection is comprehensive and accurate.

Description

technical field [0001] The invention relates to an electro-hydraulic servo automobile steering system test bench, which is mainly used for the performance test and reliability test of the automobile power steering system assembly and the comprehensive test of the automobile power steering system. Background technique [0002] The automobile steering system has always been valued by various R&D and production enterprises and institutions in the automobile industry. Its technology has changed from mechanical steering, hydraulic steering, and electronically controlled hydraulic steering to electric power steering and the next generation of wire-controlled steering. In recent years, the fastest-growing system assembly in the field of automotive technology. [0003] The steering system of a car is an important part to ensure that the car turns and runs according to the will of the driver to maintain stability. Its performance directly affects the safety and handling stability of ...

AI Technical Summary

Problems solved by technology

[0004] At present, the test of the automobile power steering system assembly mainly relies on the actual vehicle inspection, that is, the hydraulic power steering system assembly is installed on the required vehicle, and various performances of the automobile hydraulic power steering system assembly are measured in actual operation. It cannot be carried out in the laboratory, so the detection is time-consuming and laborious

Even if there are some related projects that can be carried out in the laboratory, only a certain part of the steering system, such as the performance of the steering gear, is measured, and the comprehensive performance of the entire vehicle power steering system cannot be tested.
