Description

Technical Field

[0001] The utility model relates to a brake friction plate anti-slip device, belonging to the brake field. Background Art

[0002] The friction plate is fixed to the brake bracket through an elastic plate structure. In actual use, the elastic plate has poor rigidity. When the friction plate is braked, the force is upward, so the elastic plate structure is easy to bend and deform. When the deformation of the elastic plate structure exceeds a certain range, there is a risk of the friction plate falling off if maintenance is not timely.

[0003] The traditional method is to improve the elastic plate structure to effectively fix the friction plate structure and prevent the friction plate from falling off after the elastic pressure plate is deformed beyond the range.

[0004] However, this method increases the material and processing requirements of the elastic plate structure, resulting in an increase in manufacturing costs.

[0005] If the fixing method between the friction plate and the brake can be improved, the problem of friction plate falling off may be effectively solved without increasing the manufacturing cost too much. Summary of the invention

[0006] The utility model provides a brake friction plate anti-dropping structure, which solves the problem of the friction plate dropping off due to deformation of a fixed structure affected by force.

[0012] There is an inner concave which is in an arc shape, the center of the arc is parallel to the center of the arc convexity, and the arc convexity is embedded in the inner concave.

[0013] According to the brake friction plate anti-slip structure, a pressure plate is provided on the upper part of the two friction plates, and the pressure plate presses down the friction plates through a snap structure, and both sides of the pressure plate are installed on a fixed bracket.

[0014] According to the brake friction plate anti-slip structure, the friction plate includes a metal backing plate and a friction material. The metal backing plate is a metal plate, the friction material is fixed on the metal backing plate, and the planes on both sides of the metal backing plate are provided with the arc protrusions.

The spring sheet is V-shaped, with the top corners against the upper pressure plate, and slots are provided on both sides to embed the protrusions.

[0024] The specific structure of the utility model is further described below:

[0025] The brake friction plate anti-slip structure of this device is as follows Figure 1 and Figure 2 As shown, it includes a friction plate 1 and a fixed bracket 2. The friction plates 1 are divided into two groups and are arranged in parallel in the fixed bracket 2. The two friction plates 1 are spaced a certain distance apart to prevent the friction disc from being pressed by the two friction plates to achieve the braking stop of the friction disc.

[0026] A pressure plate 5 is provided on the upper part of the two friction plates 1 , and the pressure plate 5 presses down the friction plates 1 through a buckle 7 structure. Both sides of the pressure plate 5 are installed on the fixed bracket 2 .

[0027] Specifically, Figure 4As shown, the fixing bracket 2 is provided with a mounting groove 21. Figure 1 and Figure 2 The friction plate 1 is placed as shown, and the mounting groove 21 is rectangular. The two adjacent surfaces are parallel to each other. The lower surface and the two side surfaces of the friction plate 1 are perpendicular to each other. The two side surfaces of the friction plate 1 are respectively provided with arc protrusions 3, and the center line of the arc protrusion is perpendicular to the inner friction surface of the friction plate. The two parallel side surfaces of the mounting groove 21 of the fixed bracket 2 are respectively provided with recesses 4, and the recesses 4 are arc-shaped, and the center of the arc is parallel to the center of the arc protrusion 3. The height position and size of the recess 4 match the arc protrusion, and the arc protrusion 3 is embedded in the recess 4.

[0028] The nested structure of the concave and the arc convex can prevent the friction plate from moving upward when subjected to force, thus preventing the friction plate from being separated from the fixing bracket. In other words, it can prevent the pressure plate from exceeding the structural elastic strength when the friction plate is deformed upward, resulting in excessive deformation and causing the friction plate to shift and fall off.

[0029] The friction plate of this device is as follows Figure 3 As shown, the friction plate 1 includes a metal backing plate 11 and a friction material 12 . The metal backing plate 11 is a metal plate. The friction material 12 is fixed on the metal backing plate 11 . The planes on both sides of the metal backing plate 11 are provided with the arc protrusions 3 .

[0030] Two buckles 7 are provided on the upper part of the metal back plate 11 , and a spring piece 6 is provided between the pressure plate 5 and the metal back plate 11 . The spring piece 6 is V-shaped, with the top corner against the upper pressure plate 5 , and slots 8 are provided on both sides to embed the buckles 7 .

[0031] The advantages of the utility model are: adding a concave-convex interlocking structure through the bracket is used to prevent the friction plate from jumping up and down, eliminate the force of the friction plate on the elastic pressure plate, and prevent the friction plate from falling off.

[0032] The device is improved on the existing structure, can reduce the probability of friction plate falling off, and improves the safety of the product.
