Description

Technical Field

[0001] The utility model relates to the technical field of performance test equipment, in particular to a vehicle suspension performance test device. Background Art

[0002] The suspension system refers to a connection structure system between the vehicle body, frame and wheels, and this structure system includes shock absorbers, suspension springs, anti-roll bars, suspension subbeams, lower control arms, longitudinal rods, steering knuckle arms, rubber bushings and connecting rods. When a car is driving on the road, it is subject to vibration and impact due to changes in the ground. Part of the impact force will be absorbed by the tires, but most of it is absorbed by the suspension device between the tires and the body. The car suspension needs to be tested using a car suspension test device before leaving the factory. In addition to testing the overall car suspension, the car suspension test device can also test the parts of the suspension separately. The automobile suspension test device can perform elastic fatigue test on automobile suspension springs. Because when the existing automobile suspension performance test device is testing the spring, the spring mounted on the fixed column is easy to fall off and break, which may accidentally injure the staff. In addition, the general automobile suspension performance test device needs to observe the spring during the test, and it is impossible to directly observe the state and changes of the spring, so it is impossible to understand the specific situation of the spring during the test in real time, such as spring deformation, cracks, etc. The general test device cannot test the spring under different temperature conditions, and the data may have certain differences, so it needs further improvement.
