Description

Technical Field

[0001] The utility model relates to the technical field of brake steel back wear detection, in particular to a brake steel back wear detection device. Background Art

[0002] Brake backing wear refers to the gradual loss of surface material due to friction with other components (such as brake pads and drums) during use. Just as an eraser becomes smaller when repeatedly rubbed across paper, the surface material of the brake backing is gradually worn away with repeated braking. As the backing wears, its thickness gradually decreases. This can affect the overall performance of the braking system. For example, with disc brakes, excessive backing wear can reduce the rigidity of the disc, making it more susceptible to deformation during braking, resulting in uneven contact between the brake pad and the disc. This increases stopping distance and reduces braking effectiveness and stability.

[0003] Chinese Patent No. 202223459763.1 discloses a yaw brake friction pad wear detection device, comprising a brake disc, a steel backing, and a brake drive connected to the steel backing. A friction pad is provided on one side of the steel backing, which cooperates with the brake disc. Support rods 1 and 2 are provided at the upper and lower ends of the steel backing, respectively. Support rod 1 is flanked by fixed plates 1 and 2, respectively. Fixed plate 1 is provided with a detection sensor that cooperates with the friction pad, and fixed plate 2 is provided with a buzzer alarm that cooperates with the detection sensor. Support rod 2 is provided with a fixed plate 3 on one side, and fixed plate 3 is provided with a reflector that cooperates with the detection sensor. This device has the advantage over existing technologies in that, through the coordination of the detection sensor, reflector, and buzzer alarm, a reminder is provided when the friction pad needs replacement, eliminating the need for regular disassembly and inspection by personnel, making it more convenient.

[0004] Existing brake steel back wear detection devices usually use an electric eye that shines vertically downward or directly use a measuring ruler to detect the thickness of the brake steel back to determine the wear degree of the brake steel back. However, during the use of the brake, the force point between the steel back and the brake pad is in the middle position, which causes the middle position of the steel back to be severely worn, while the wear on the upper and lower and left and right four sides is relatively light. However, during the detection process, the existing device is blocked by the thicker part of its side, which makes it inconvenient to detect the thickness of the middle part with heavier wear and is prone to errors.

[0005] In view of the above problems, a brake steel back wear detection device is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a brake steel back wear detection device, which solves the problem in the background art that errors are easily present in the detection of the middle position of the steel back which is subject to greater wear.
