Abstract

The invention discloses an oil-gas suspension test bench. The test bench adopts a four-column structure, including a base and a lower beam installed on the base. The lower beam and the top upper beam are fixedly connected by four optical axis columns. Slider assembly 1 and slider assembly 2 are installed on the optical axis column between the beam and the upper beam. The tension-compression force sensor is installed between the oil-pneumatic suspension and the two slider assemblies. The bottom of the slider assembly 2 is equipped with a hydraulic In the locking device, a counterweight is placed on the upper end of the slider assembly 2, and the lower part of the slider assembly 1 is connected with the tire assembly, and the tire assembly directly falls on the self-guiding cylinder. The self-guiding actuator is vertically installed on the base of the bench, which can directly or indirectly transmit the excitation to the oil-air suspension, providing different forms of excitation for the oil-air suspension test.

Description

technical field [0001] The invention relates to the technical field of automobile operation, in particular to an oil-gas suspension test bench. Background technique [0002] At present, there are two main forms of oil and gas suspension testing. One is the vehicle road simulation test system, and the other is the static loading test system. [0003] Among them, the vehicle road simulation test system can simulate the driving conditions of the vehicle under different road conditions, and is generally a four-column road simulation system or a six-column road simulation system. The system needs to use two or more independent coordinates to describe the vibration system of its motion, each degree of freedom is related to each other, and the vibration of a certain degree of freedom often leads to the vibration of the whole system. The test system is complex, the installed power is large, and the cost of equipment manufacturing and testing is high. Generally, it is only applica...
