Durable test stand and test method of gas spring for automobile

Abstract

The invention discloses a gas spring durable test bed and test method for vehicles, the main structure of the test bed is composed of a bed body, a beam, two adjustable posts, and a simulative door, wherein the main structure is in symmetric structure, two adjustable posts are symmetrically arranged on two-side edge of the bed body, the simulative door is arranged on the beam through a vehicle hinge, a tension cylinder, a pulley, a lifting cylinder are arranged on the central symmetric line of horizontal plane of the bed body. In the case of performing the test, the test method comprises: arranging the two ends of the gas spring assembly on the upper end of the adjusting post and the simulative door; adjusting the fixed position of the gas spring assembly on the adjusting post and the simulative door to achieve the use stoke for normal working of the gas spring, outputting corresponding signal through a programmable controller to control lift and compression of the gas spring. The gas spring durable test bed for vehicles, which is driven by a cylinder, has reasonable structure, strong flexibility, simple operation, no noise when working, identical movement mode of the device with working condition of vehicles.

Description

technical field [0001] The invention belongs to the technical field of automobile product testing, and relates to a gas spring durability test bench, in particular to a mechanical detection device for a vehicle gas spring durability test for simulating front and rear compartment covers of passenger cars. Background technique [0002] There are many kinds of gas springs on the front and rear hatches of automobiles. During use, the gas springs support the overall quality of the front and rear hatches. Obviously, the safety of the gas springs is the primary issue, and the durability of the gas spring itself determines its service life. It also directly affects its safety, so it is necessary to test the durability of various mechanisms in the gas spring. At present, the durability test of the gas spring is driven by a motor and a reducer, and the drive is clumsy. The working direction of the gas spring is simple vertical up and down, and the forced external force is used to driv...

AI Technical Summary

Problems solved by technology

At present, the durability test of the gas spring is driven by a motor and a reducer, and the drive is clumsy. The working direction of the gas spring is simple vertical up and down, and the forced external force is used to drive the gas spring to complete the stretching and compression stroke. Without the installation of the automobile hinge, it cannot be completely Simulate the actual use state of the gas spring

For example, the application number is CN03212722.7, and the title of invention is the compressible gas spring durability test bench. The working conditions are not in compliance, the fixing method of the gas spring cannot be adjusted, and the noise of the equipment is loud, which will cause the abnormal sound defect of the tested gas spring sample to be unable to be found when it is durable. Only one sample can be made at a time, the work efficiency is low, and only gas spring durability tests can be done, and the versatility of the equipment is poor
