Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption performance testing, in particular to a testing device for the performance of a motorcycle shock absorber. Background Art

[0002] Motorcycle shock absorbers are an important part of the motorcycle suspension system. Their main function is to alleviate and attenuate the impact and vibration caused by uneven road conditions during the driving of the motorcycle, ensure the smoothness and comfort of the driving, and improve the stability and handling of the motorcycle.

[0003] In order to ensure the safety and performance of motorcycles, performance tests are performed on motorcycle shock absorbers. Motorcycle shock absorbers are subjected to continuous vibration and impact in actual use. Long-term use will reduce the life of motorcycle shock absorbers. Therefore, fatigue detectors are needed to detect the fatigue life of motorcycle shock absorbers. In the process of fatigue detection of motorcycle shock absorbers by existing fatigue detectors, hydraulic columns are used to drive the motorcycle shock absorbers to stretch. The hydraulic columns that are repeatedly raised and lowered for a long time will cause the hydraulic oil inside the hydraulic columns to heat up, affecting the stability and safety of the hydraulic system inside the hydraulic columns, as well as the load-bearing capacity and service life of the hydraulic cylinders, which may cause errors in the test results. The problem with the above technology is that the motorcycle shock absorbers are repeatedly stretched by the hydraulic columns, which will affect the accuracy of the test results due to the temperature rise of the hydraulic oil.
