[0002] At present, the brake is provided with a slot hole structure for heat dissipation and observing the friction plate at the friction plate position. The slot hole can dissipate heat from the friction plate and is convenient for observing the wear degree of the friction plate during maintenance.

[0003] The lower pressing fixing plate provided with the friction plate is used to press and fix the friction plate to prevent the friction plate from being separated from the caliper due to force.

[0004] Since there are stones, sand, rain and snow on the driving road surface of the vehicle, foreign objects often splash into the space between the friction plate and the brake disc during driving, resulting in a greater risk.

[0005] Completely closing the slot hole will cause problems in heat dissipation and maintenance. Content of the Utility Model

The protective cover body covers the slot hole at the friction plate of the brake, the arc-shaped support plates contact the edge of the slot hole, and the protective cover body is at a certain distance from the brake caliper; the space between the two arc-shaped support plates is communicated with the slot hole;

[0009] The middle of the protective cover body is divided into an upper fixing plate and a lower fixing plate, and a friction plate spring fixing plate is arranged between the upper fixing plate and the lower fixing plate in a penetrating manner.

[0010] According to the friction plate protective cover of the brake, the upper fixing plate is in the middle, the lower fixing plates are on both sides, and the widths of the two lower fixing plates on both sides are the same.

[0011] According to the friction plate protective cover of the brake, the upper fixing plates are on both sides, the lower fixing plate is in the middle, and the widths of the two upper fixing plates on both sides are the same.

[0012] According to the friction plate protective cover of the brake, a gap is arranged between the upper fixing plate and the lower fixing plate, and a circular cut groove is cut at the end of the gap.

[0013] According to the friction plate protective cover of the brake, a protruding distance fixing plate is arranged on the upper fixing plate or the lower fixing plate close to the brake arm side and contacts the edge of the slot hole at the friction plate of the brake.

[0014] According to the friction plate protective cover of the brake, it is characterized in that the end of the arc-shaped support plate is a circular arc-shaped strip, and the connection angle position between the arc-shaped support plate and the protective cover body is a rounded corner.

[0015] The advantages of the present utility model are as follows: it realizes the shielding of the slot holes at the friction plate to prevent foreign objects from entering; there is a gap reserved between the protective cover and the pliers body, which can effectively dissipate heat from the friction plate;

[0016] The protective cover is nested with the friction plate spring fixing plate, and there is no need to modify and install additional components to the existing brake structure. Description of the Drawings

[0023] The following is an explanation of the specific structure of the present utility model:

[0024] The friction plate protective cover of the brake of the present utility model, the protective cover body 1 is an arc-shaped plate, made of a metal plate structure, with rust-proof material or added rust-proof components.

[0025] The top view of the protective cover body is rectangular, and arc-shaped support plates 2 that bend towards the center of the arc-shaped plate are provided on both short sides. The end of the arc-shaped support plate 2 is a circular arc-shaped strip, which is consistent with the arc of the protective cover body 1. The connection angle position between the arc-shaped support plate 2 and the protective cover body 1 is a rounded corner.

[0026] The protective cover body 1 covers the slot hole 4 at the friction plate of the brake 3, the arc-shaped support plate 2 contacts the edge of the slot hole 4, and the protective cover body 1 is at a certain distance from the brake 3 through the arc cost; the space between the two arc-shaped support plates 2 is communicated with the slot hole 4; air can enter the slot hole through the above space to dissipate heat from the friction plate, and as the wheel brake disc rotates, air enters through the gap between the arc-shaped support plates at one end of the slot hole and exits at the other end, forming air convection to accelerate heat dissipation.

[0027] In order to effectively fix the protective cover body 1, it is divided into an upper fixing plate and a lower fixing plate in the middle, and a friction plate compression spring fixing plate 10 is inserted between the upper fixing plate and the lower fixing plate. There is a gap between the upper fixing plate and the lower fixing plate, and a circular cut groove 7 is cut at the end of the gap.

[0028] Open a screw hole at the position of the upper fixing plate or the lower fixing plate in the middle of the protective cover body 1, and fix it to the friction plate compression spring fixing plate 10 through a screw.

[0029] The upper fixing plate or the lower fixing plate is provided with a protruding distance fixing plate 8 on the side close to the brake arm, and contacts the edge of the slot hole 4 at the friction plate of the brake 3.

[0030] There are two ways for the parts of the upper fixing plate and the lower fixing plate in this device.

[0031] In one embodiment as shown in Fig. 1, the upper fixing plate is in the middle, and the lower fixing plates are on both sides, and the widths of the lower fixing plates on both sides are the same.

[0032] In another embodiment, the upper fixing plates are on both sides, and the lower fixing plate is in the middle, and the widths of the upper fixing plates on both sides are the same.

[0033] This protective cover can block the slot hole at the friction plate to prevent foreign objects from entering.

[0034] A gap is reserved between the protective cover and the pliers body, and air can enter the slot hole to effectively dissipate heat from the friction plate.

[0035] This protective cover is nested with the friction plate compression spring fixing plate, and there is no need to transform and install the existing brake structure, which can save the transformation cost of existing equipment.
