[0018] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 3 As shown, the spring sheet for eliminating the sliding gap of the brake block is arranged between the brake block clamping foot 3 of the brake block and the bracket clamping spring 5 of the brake block bracket 4, as shown in FIG. Figure 1As shown, the spring sheet includes a clamping portion 1 and an elastic portion 2 that are integrally formed and sequentially connected, the elastic portion 2 includes a C-shaped elastic arm 22 and a V-shaped elastic arm, wherein the clamping portion 1, the C-shaped elastic arm 22 and the V-shaped elastic arm are sequentially connected;

[0020] The clamping part 1 of the spring sheet is clamped on the end face of the brake pad foot 3 of the brake pad, the C-shaped opening of the C-shaped elastic arm 22 is arranged toward the end face of the brake pad foot 3, and the V-shaped opening of the V-shaped elastic arm is arranged toward the side of the brake pad foot 3. The end of the V-shaped elastic arm contacts the clamping part 1 of the spring sheet, and the outer wall of the V-shaped opening of the V-shaped elastic arm is a V-shaped contact point 21. The V-shaped contact point 21 of the V-shaped elastic arm conflicts with the bracket retaining spring 5. When the car brakes, an abnormal sound is generated due to the sliding gap between the brake pad and the brake pad bracket 4. The gap between the brake pad foot 3 and the bracket retaining spring 5 is reduced by deformation of the C-shaped elastic arm 22 and the V-shaped elastic arm, thereby solving the problem of large sliding gap between the brake pad and the brake pad bracket 4, causing the brake pad to knock back and forth between the sliding grooves, thereby generating noise or abnormal sound.

[0021] Specifically, the clamping part 1 is U-shaped as a whole, and is divided into a clamping inner wall 11, a clamping middle wall and a clamping outer wall 12 which are connected in sequence; the clamping inner wall 11 and the clamping outer wall 12 are respectively two side edges of the U-shape, and the clamping middle wall is the middle edge of the U-shape. The clamping inner wall 11 and the clamping outer wall 12 are connected through the clamping middle wall to clamp and fit the two side end faces of the brake block foot 3 respectively, and the two side end faces are respectively two end faces of the brake block along the braking direction, and the clamping middle wall is fitted to the side of the brake block foot 3. The connection between the clamping inner wall 11 and the clamping outer wall 12 and the clamping middle wall respectively has a certain curvature, and the length of the clamping outer wall 12 is greater than the length of the clamping inner wall 11; the end of the clamping outer wall 12 is connected to the C-shaped elastic arm 22; the end of the clamping outer wall 12 is connected to the C-shaped elastic arm 22, and the end of the V-shaped elastic arm is in contact with the connection between the clamping inner wall 11 and the clamping middle wall.

[0022] like Figure 2 As shown, a groove is formed on the end face of the clamping outer wall 12, and a barb 13 is arranged in the groove. One end of the barb 13 is connected to the middle of the head end of the C-shaped elastic arm 22, and the other end of the barb 13 extends to the middle of the groove on the end face of the clamping outer wall 12. The barb 13 and the brake block foot 3 are arranged non-parallel, and the angle between the barb 13 and the clamping outer wall 1 is 30 degrees. The barb 13 is embedded in the groove hole formed on the rear end face of the brake block foot 3 for fixation.

[0023] The assembly and working process of the spring leaf are as follows:

[0024] When assembling the brake caliper, first install the bracket retaining spring 5 on the brake pad bracket 4. When the brake pad is assembled, the brake pad foot 3 has been installed with the spring sheet and is inserted into the sliding groove of the bracket retaining spring 5. During the braking process of the vehicle, the V-shaped contact point 21 conflicts with the bracket retaining spring 5, and the sliding surface gap between the brake pad foot 3 and the bracket retaining spring 5 is adjusted by the joint deformation of the C-shaped elastic arm 22 and the V-shaped elastic arm, thereby reducing the sliding surface gap.
