Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake system testing, in particular to an auxiliary tooling for automobile brake system testing. Background Art

[0002] The automobile braking system refers to a series of specialized devices that apply a certain force to certain parts of the automobile (mainly the wheels) to force braking to a certain extent. The functions of the braking system are: to force the moving car to slow down or even stop according to the driver's requirements; to keep a stopped car parked stably under various road conditions (including on ramps); to keep the speed of a car traveling downhill stable. The braking system is usually inspected and tested before the car goes on the road.

[0003] Please refer to the automobile brake system test auxiliary tooling with announcement number CN215178634U. In this patent, it is proposed that "when testing the automobile brake system, a brake test bench is usually used to slow down or even stop the wheel at different speeds, but when running at high speed, the test bench usually vibrates violently, causing detection errors and damage to the ground." The above embodiment fixes the fixing column by a nut, and a protective pad is placed between the nut and the fixing column. A support shaft is welded on the protective pad. The support shaft is provided with a support plate fixed to the ground to prevent vibration. A support column is arranged in the middle of the fixing column. The spring between the support column and the fixing column reduces the downward impact force to prevent the equipment from bouncing up due to excessive vibration.

[0004] However, in the above patent document, damage to the ground is prevented by setting a support plate and a rubber pad at the bottom of the support shaft. However, the support plate on the support shaft is small in size and has a narrow cross-sectional area with the ground. During vibration, the rubber pad alone cannot effectively reduce damage to the ground, and its practicality is poor. In the above patent, buffering is only achieved by the spring between the support column and the fixed column. However, the support column is set on the inner side of the support shaft, and its range of motion is limited, and it cannot achieve a good buffering effect. The present application proposes another technical solution to solve this technical problem. Utility Model Content
