Problems solved by technology

[0003] When the existing pneumatic disc brake is in use, although it has a braking effect on the tires, it is impossible to know the wear of the two brake pads in time, that is, whether the wear position has reached the maximum amount of wear, thus causing the brake pads to wear out. After severe wear and tear, it is impossible to know in time, which leads to certain safety hazards in the long-distance use of the car

Embodiment 1

[0032] Embodiment one, such as Figure 7 As shown, the automobile brake brake pad wear monitoring device includes a first observation hole 21 arranged between the inner wall 25 and the outer wall 24 of the brake pad 2, the inner wall 25 is facing the brake disc 1, and the first observation hole 21 is embedded A first observation piece 3 is provided; the first observation piece 3 includes a first end portion 31 facing the outer wall 24 , and the first end portion 31 is located in the first observation hole 21 . Brake pad 2 is installed on the support 6, and is equipped with shield 7. In the process of braking, the constant friction between the brake pad 2 and the brake disc 1 produces consumption, and at the same time, the first observation member 3 will be worn, until the first end 31 is worn and the first observation hole 21 can be worn through. The brake disc 1 can be seen from the outside of the brake pad 2 through the first observation hole 21. When the first end 31 is wo...

Embodiment 2

[0033] Embodiment 2, embodiment 2 is to increase the second observation hole 22 and the second observation member 4 on the basis of the embodiment 1, specifically the second observation hole 22 is also provided between the inner wall 25 and the outer wall 24 of the brake pad 2, The second observation hole 22 is embedded with a second observation piece 4; the second observation piece 4 includes a second end 41 facing the outer wall 24, and the second end 41 is located in the second observation hole 22, such as Figure 8 shown.

[0034] In an embodiment, the distance from the second end 41 to the inner wall 25 is equal to the distance from the first end 31 to the inner wall 25, such as Figure 8 shown. If the wear time of the first end portion 31 and the second end portion 41 differ greatly, it means that the wear of the brake pad 2 is uneven, and the brake pad 2 should be calibrated.

Embodiment 3

[0035] Embodiment 3, the structure of embodiment 3 is basically the same as that of embodiment 2, the difference is that the distance from the second end 41 to the inner wall 25 is smaller than the distance from the first end 31 to the inner wall 25, as Figure 9 shown. When the second observation member 4 is completely worn out, it can be used as a first warning, prompting people to replace the brake pads 2 before the first end portion 31 is worn out.

Abstract

The invention discloses a device for monitoring an abrasion conditions of a brake pad of an automobile brake. The device comprises a first observation hole, wherein a first observation piece is arranged inside the first observation hole; the first observation piece comprises a first end part facing the outer wall, and the first end part is located inside the first observation hole; and in addition, a second observation piece is further arranged. In the braking process, the brake pad and a brake disc are continuously abraded and consumed, and meanwhile, the first observation piece can be abraded until the first end part is abraded so that the first observation hole can be abraded to be through, people can peep to the brake disc from the outer side of the brake pad through the first observation hole, and when the first end part is abraded to be through, it means that the brake pad is abraded to preset thickness, and the wear critical warning thickness can be set by presetting the position of the first end part in the first observation hole or presetting the length of the first observation piece; the second observation piece and the first observation piece can judge abrasion and uneven abrasion together; and the device is reasonable in structure layout, and can conduct detection without professional equipment, and the abrasion condition of the brake pad can be observed and judgedfrom the outer side of the brake pad.

Description

technical field [0001] The invention belongs to the field of automobile brakes, in particular to a monitoring device for the wear condition of brake pads of automobile brakes. Background technique [0002] The pneumatic disc brake is installed on the wheel shaft and rotates synchronously with the wheel. The disc brake is mainly divided into: bracket and shield, pin shaft, flange, brake disc, brake pad, caliper. When braking, the brake caliper is clamped The brake disc, the brake disc and the wheel are coaxially fixed, the brake disc and the brake pad contact to produce braking, that is, the caliper generates braking torque under the push of pressure, and the brake pad clamps the brake disc under the push of the piston, braking The moving disc and the wheel decelerate or stop rotating together, and the constant friction between the brake pads and the brake disc produces consumption. In order to ensure the normal braking function, it is necessary to regularly check and replace...
