Abstract

The invention provides a damping piston debugging system for an oil damper. The damping piston debugging system for the oil damper comprises a hydraulic cylinder and a damping piston debugging fixture, wherein the hydraulic cylinder is connected with the damping piston debugging fixture through a reversing valve I and a reversing valve II. The damping piston debugging fixture comprises a sealing cover I, a sealing cover II and an adjustment device, wherein a damping piston is clamped between the sealing cover I and the sealing cover II; and the adjustment device comprises at least one single adjustment element, and the single adjustment elements are arranged on the sealing cover I or the sealing cover II, form one-to-one correspondence with adjustment valves on the damping piston, and areused for adjusting the flow rates of the adjustment valves. According to the damping piston debugging system for the oil damper, the hydraulic cylinder is used as a pressure source of the system; pressure oil is bidirectionally provided for the damping piston debugging fixture by stretching or compressing a piston rod of the hydraulic cylinder, the plurality of adjustment valves reversely arrangedon the damping piston can be adjusted, and the actual use environment of the damping piston is simulated. With the adoption of a two-position three-way hydraulic control valve, the automatic reversing of the system is realized; and a shuttle valve and a safety valve are designed, so that the safety of the system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission, in particular to a damping piston debugging system for an oil pressure shock absorber. Background technique [0002] Oil shock absorber is an important part of various vehicles, and its damping characteristics directly affect the safety, stability and comfort of vehicle operation. The damping piston is an important component of the damping force of the hydraulic shock absorber. Whether it can efficiently and accurately adjust the required damping force is crucial to the performance and production of the hydraulic shock absorber. In the prior art, the adjustment of the damping force of this type of hydraulic shock absorber must be repeatedly disassembled, adjusted, and tested on a test bench until the damping force of the damping piston meets the requirements. This seriously affects the efficiency and accuracy of damping force adjustment of this type of oil pressure shock absorber....
