Description

Technical Field

[0001] The utility model relates to the relevant field of oil pressure shock absorbers, in particular to an oil pressure shock absorber which is conducive to heat dissipation. Background Art

[0002] Oil shock absorbers are key components of rail transit equipment such as electric locomotives, diesel locomotives, and subway trains. Their main function is to attenuate vibration and impact during the operation of locomotives and vehicles, improve ride comfort, and ensure the safety of locomotives and vehicles.

[0003] The working principle of the current hydraulic shock absorber is: converting kinetic energy into heat energy. Specifically, when the piston is stretched, the one-way valve on the piston is closed, the pressure in the rod chamber increases, and the hydraulic oil in the rod chamber opens the overflow valve to do work. At this time, the temperature of the hydraulic oil increases, and the heated hydraulic oil flows into the oil storage chamber through the oil guide pipe;

[0004] The hydraulic oil heated up during the stretching stroke of the existing hydraulic shock absorber flows directly into the oil cylinder, causing the high-temperature hydraulic oil to directly enter the oil cylinder, reducing the heat exchange between the hydraulic oil and the external environment, reducing the heat dissipation of the shock absorber, and making it prone to damage. At the same time, most of the hydraulic shock absorbers in the prior art do not have the ability to seal and protect the expansion joint, and are easily invaded by dust particles during use, resulting in wear and abnormal noise problems. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content
