The brakes currently on the market are designed with a large size of the avoidance groove in order to avoid the column from touching the caliper body as much as possible, which results in the wall thickness of the caliper body at the avoidance groove becoming thinner, and the structural strength of the corresponding caliper body will be affected to a certain extent. Utility Model Content

[0008] A pair of avoidance grooves for avoiding the columns are also opened on the inner wall of the U-shaped opening at a pair of columns near the side of the bridge frame docking section, the avoidance groove has a top surface, a bottom surface, and a first side surface and a second side surface connecting the top surface and the bottom surface, wherein the first side surface is located on the side close to the center of the U-shaped opening, the top surface and the bottom surface are both inclined inclined surfaces, and the inclination direction is gradually inclined upward from the side close to the center of the U-shaped opening, the first side surface is a vertical plane, the second side surface is an inclined surface, and the second side surface is a combined surface composed of a first arc segment and a second arc segment connected in sequence from top to bottom, the arc opening of the first arc segment is facing away from the U-shaped opening, and the arc opening of the second arc segment is facing the U-shaped opening.
[0009] Furthermore, the length of the top surface of the avoidance groove is between 1 / 4 and 2 / 5 of the length of the bottom surface of the avoidance groove.

[0022] The following embodiments may enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.
[0023] like Figure 1-Figure 5 The disc brake shown comprises a caliper body 1 and a bracket 2 arranged below the caliper body 1 .
[0024] like Figure 2 As shown in the schematic diagram, the caliper body 1 includes a box docking section 11, a bridge docking section 12 and an intermediate connecting section 13 connecting the box docking section 11 and the bridge docking section 12. The box docking section 11, the bridge docking section 12 and the intermediate connecting section 13 together form a square-shaped opening 14 for installing the brake lining of the disc brake.
[0025] like Figure 5 As can be seen from the schematic diagram shown, two pairs of columns for installing brake pads of disc brakes are arranged on the upper end surface of the bracket 2, and the two pairs of columns extend into the U-shaped opening 14, one pair of columns is located on the side close to the box docking section 11, and the other pair of columns is located on the side close to the bridge docking section 12, each pair of columns is composed of two columns 21 distributed on both sides of the bracket, the column 21 is in the shape of a right triangle, and one of the right-angled sides of the column 21 is connected to the bracket, the other right-angled side of the column 21 is located on the side close to the center of the bracket 2, and the inclined surface of the column 21 is located on the side away from the center of the bracket 2.
[0026] A pair of escape grooves 3 for evading the columns 21 are also provided on the inner wall of the U-shaped opening 14 at a pair of columns near the bridge butt joint section 12. Figure 4As shown in the schematic diagram, the avoidance groove 3 has a top surface 31, a bottom surface 32, and a first side surface 35 and a second side surface connecting the top surface 31 and the bottom surface 32, wherein the first side surface 35 is located on a side close to the center of the U-shaped opening 14, the top surface 31 and the bottom surface 32 are both inclined inclined surfaces, and the inclination directions of the top surface 31 and the bottom surface 32 are both gradually inclined upward from the side close to the center of the U-shaped opening 14, the first side surface 35 is a vertical plane, the second side surface is an inclined surface, and the second side surface is composed of a first arc segment 33, a second arc segment 34 connected in sequence from top to bottom. The combined surface composed of the first arc segment 33, the arc opening of the second arc segment 34 faces the U-shaped opening 14, the first arc segment 33 and the second arc segment 34 are both close to a straight line. Since the second side surface is the longest among the four surfaces constituting the entire avoidance groove 3, if the second side surface is directly processed into an inclined smooth surface, the processing difficulty is relatively large. The use of the combined surface of the first arc segment 33 and the second arc segment 34 allows a certain margin to be provided during processing, which is more convenient for subsequent processing.
[0027] The length of the top surface 31 of the avoidance groove 3 is between 1 / 4 and 2 / 5 of the length of the bottom surface 32 of the avoidance groove 3. The length of the top surface 32 of the avoidance groove 3 is designed to be between 1 / 4 and 2 / 5 of the length of the bottom surface 32 of the avoidance groove 3. By controlling the length between the top surface 31 and the bottom surface 32, the avoidance groove 3 finally formed can better form a contoured cavity that matches the column 21, providing a basis for achieving the purpose of reducing the size of the avoidance groove 3 as much as possible while avoiding the column 21 well.
[0028] The inclination amplitude of the top surface 31 of the avoidance groove 3 is smaller than the inclination amplitude of the bottom surface 32 of the avoidance groove 3. The inclination amplitude of the top surface 31 of the avoidance groove 3 is designed to be smaller than the inclination amplitude of the bottom surface of the avoidance groove 3. Since the inclination amplitude of the top surface 31 is relatively small, the wall thickness of the clamp body 1 at the top surface 31 will be relatively increased, thereby improving the strength of the clamp body 1 at the top surface 31 of the avoidance groove 3.
[0029] The top surface 31 of the avoidance groove 3 has an upwardly protruding arc surface 36 on one side close to the center of the square-shaped opening 14, and the length of the arc surface 36 is less than 1 / 2 of the length of the top surface of the avoidance groove 3. The upwardly protruding arc surface 36 designed on the top surface of the avoidance groove 3 is designed to increase the avoidance space here in consideration of the structural characteristics of the column 21, and at the same time, the length of the arc surface 36 is controlled to be less than 1 / 2 of the overall length of the top surface 31, so as to reduce the length of the arc surface 36 as much as possible, so that the wall thickness of the rest of the pliers body 1 is guaranteed because the arc surface 36 is not needed, and the relative structural strength can be guaranteed, thereby reducing the influence of the arc surface 36 on the overall structural strength of the pliers body 1.
[0030] By redesigning the avoidance groove 3, the avoidance groove 3 adopts a method of adopting a combined inclined second side surface formed by connecting an inclined top surface 31 and a bottom surface 32, a vertical first side surface 35 and two arc segments, so that the avoidance groove 3 can be more closely matched with the shape of the column 21. By adopting this contoured design, the depth of the avoidance groove 3 can be reduced, and a good avoidance space can be provided to the column 21, which can also improve the structural strength of the clamp body. In addition, the avoidance groove does not directly adopt the form of a triangular groove that is proportionally enlarged with the column 21. This is because the processing difficulty and the influence on the strength of the clamp body are taken into consideration. If the triangular avoidance groove 3 is directly processed, it is more difficult, especially the sharp corner processing at the top of the avoidance groove is more troublesome, and a certain avoidance space must be left for the column 21. In addition, it is more difficult to control the size of the avoidance groove 3. In order to provide a good avoidance space for the column 21, the size of the avoidance groove 3 may need to be opened larger, which will affect the strength of the clamp body 1.
