Abstract

The invention provides a test device of an oil and gas suspension system. The test device comprises a foundation, the oil and gas suspension system, an excitation hydraulic cylinder, a pressure sensor connected with the excitation hydraulic cylinder and a hydraulic servo control system used for controlling motion of the excitation hydraulic cylinder, wherein the oil and gas suspension system comprises one or more oil and gas suspension cylinder sets mounted on the foundation and an energy storage device connected with the oil and gas suspension cylinder set through a pipeline, the two oil and gas suspension cylinders of the oil and gas suspension cylinder set are connected in an opposite mode through a connection head, the excitation hydraulic cylinder is mounted on the foundation, and a cylinder lever of the excitation hydraulic cylinder is parallelly connected with the middle portion of the connection head. The test device is advantaged in that test analysis on inclination performance of the one or more oil and gas suspension cylinder sets is realized through the one excitation hydraulic cylinder, and test cost is substantially reduced.

Description

technical field [0001] The invention belongs to the technical field of bench tests for oil-gas suspension systems, and in particular relates to a test device for oil-gas suspension systems. Background technique [0002] As one of the main components of heavy-duty vehicles, the oil-pneumatic suspension functions to transmit the force and moment acting between the wheels and the frame, and to buffer the impact force transmitted from the uneven road to the frame or body, and to attenuate the impact caused by it. The vibration of the oil-pneumatic suspension is directly related to the overall performance of the vehicle to ensure the smooth driving and driving comfort of the vehicle. [0003] In order to fully inspect and test the comprehensive performance of the oil-pneumatic suspension, a special test bench is needed to inspect and test the oil-pneumatic suspension. Most of the existing test benches are only suitable for the characteristic analysis of a single oil-pneumatic su...
