Description

Technical Field

[0001] The utility model relates to the technical field of brake pad testing, in particular to a high-strength corrosion-resistant testing device for automobile brake pads. Background Art

[0002] Automotive brake pads, also known as brake leather, are the friction material attached to the brake drum or disc that rotates with the wheel. The friction lining and pads within the brake pads withstand external pressure, generating friction to decelerate the vehicle. Before use, brake pads must undergo a high-intensity corrosion resistance test to understand their corrosion resistance.

[0003] However, the existing high-strength corrosion-resistant test device for automobile brake pads has the following disadvantages:

[0004] (1) The existing high-strength corrosion resistance test device for automobile brake pads has a weak salt spray uniformity test function. During the salt spray test on the outer surface of the brake pad, the salt spray is uneven, resulting in part of the brake pad not being sprayed with salt spray, which affects the test results.

[0005] (2) The existing high-strength corrosion resistance test equipment for automobile brake pads has a weak function of collecting the corrosive liquid on the surface of the brake pad after the test. When in use, it is unable to collect the corrosive liquid adhering to the surface of the brake pad, causing subsequent damage to the human body or the environment. Utility Model Content
