Abstract

The invention discloses a hydro-pneumatic suspension test bed which is of a four-stand-column structure and comprises a base and a lower cross beam installed on the base, the lower cross beam is fixedly connected with a top upper cross beam through four optical axis stand columns, and a first sliding block assembly and a second sliding block assembly are installed on the optical axis stand columns between the lower cross beam and the upper cross beam. A tension-compression type force sensor is installed between a hydro-pneumatic suspension and the two sliding block assemblies, the hydraulic locking device is arranged at the bottom of the second sliding block assembly, a balance weight is placed at the upper end of the second sliding block assembly, the lower portion of the first sliding block assembly is connected with the tire assembly, and the tire assembly directly falls on the self-guiding actuating cylinder. The self-guiding actuating cylinder is vertically installed on a rack base and can directly or indirectly transmit excitation to the hydro-pneumatic suspension, and excitation of different forms is provided for the hydro-pneumatic 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...
