Description

Technical Field

[0001] The utility model relates to the field of disc brakes, in particular to a lightweight disc brake caliper body. Background Art

[0002] The disc brake is mainly composed of an air chamber, brake pads, caliper body, push rod, lever, adjustment mechanism, bracket and other parts. Among them, the brake disc is connected to the front wheel hub with bolts and is the rotating part of the friction pair. The brake pads are located on both sides of the brake disc under the limiting action of the bracket and are the fixed part of the friction pair.

[0003] As an important component of the disc brake, the quality of the caliper is directly related to the overall quality of the disc brake. In order to improve the quality of the caliper, the caliper used in the market is usually made thicker to improve its structural strength. For example, the caliper of a car floating caliper disc brake mentioned in patent CN217152764U has a relatively backward caliper structure, especially for its reinforcement, which is used to enhance the structural strength of the caliper. Therefore, the reinforcement is made relatively backward and larger in size during manufacturing, and the corresponding weight is increased. Although the structural strength of the caliper is improved, the weight of the caliper is also increased. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a lightweight disc brake caliper body which can reduce the weight of the caliper body on the basis of ensuring the structural strength of the caliper body.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a lightweight disc brake caliper, the innovation of which is: comprising

[0006] A caliper body, the caliper body comprising a box docking section, a bridge docking section and an intermediate connecting section connecting the box docking section and the bridge docking section, the box docking section, the bridge docking section and the intermediate connecting section together forming a square-shaped opening for mounting a brake lining of a disc brake;

[0007] The middle connecting section is composed of two connecting segments, and the connecting segments are inclined, and the inclination direction is from the top end of the connecting segment to the bottom end of the connecting segment and gradually inclines away from the center direction of the U-shaped opening;

[0008] The connecting segment has an arc-shaped top surface, an arc-shaped bottom surface, and an inner side wall and an outer side wall connecting the arc-shaped top surface and the arc-shaped bottom surface. The inner side wall of the connecting segment includes a first oblique line segment, a second oblique line segment, a third oblique line segment, and a fourth oblique line segment distributed in sequence from top to bottom. The inclination direction of the first oblique line segment, the second oblique line segment, and the fourth oblique line segment is gradually inclined from top to bottom toward the center direction away from the U-shaped opening, and the first oblique line segment and the second oblique line segment are connected together to form a V-shaped structure, and the apex of the V-shaped structure faces the U-shaped opening, and the third oblique line segment is connected to the inner side wall of the connecting segment. The arc-shaped opening direction of the segment is toward the U-shaped opening, and the outer side wall of the connecting segment includes a fifth oblique line segment, a sixth arc-shaped segment, a seventh oblique line segment, an eighth arc-shaped segment, a ninth oblique line segment and a tenth oblique line segment which are distributed in sequence from top to bottom, wherein the inclination direction of the fifth oblique line segment, the seventh oblique line segment and the ninth oblique line segment is gradually inclined from top to bottom toward the center direction away from the U-shaped opening, the inclination direction of the tenth oblique line segment is gradually inclined from top to bottom toward the center direction close to the U-shaped opening, and the arc-shaped opening directions of the sixth arc-shaped segment and the eighth arc-shaped segment are away from the U-shaped opening.

[0009] Furthermore, the diameter of the circle where the arc-shaped top surface is located is smaller than the diameter of the circle where the arc-shaped bottom surface is located.

[0010] Furthermore, the sixth arc segment and the seventh oblique line segment are connected by an arc-shaped transition, and the eighth arc segment and the ninth oblique line segment are connected by an arc-shaped transition.

[0011] The advantages of the utility model are as follows: the pliers body of the utility model adopts the design of inclined connecting segments by redesigning the structure of the middle connecting section, and then cooperates with the design of arc segments and oblique line segments at different positions of the connecting segment itself, so that the inner and outer side surfaces of the connecting segment are no longer a smooth surface. Based on such a design, the position of the connecting segment with high strength requirements is made thicker, while the other positions are made thinner, which can meet the structural requirements of the middle connecting section and reduce the weight of the middle connecting section, providing a good foundation for subsequently reducing the weight of the entire pliers body.

[0012] The diameter of the circle where the arc top surface is located is designed to be smaller than the diameter of the circle where the arc bottom surface is located, so that the connecting segment can form a structure that is small at the top and large at the bottom, thereby making the upper part of the connecting segment thinner and reducing the weight of the connecting segment.

[0013] The arc-shaped transition connection is adopted between the sixth arc segment and the seventh oblique line segment, and the arc-shaped transition connection is adopted between the eighth arc segment and the ninth oblique line segment, in order to make the connection between the sixth arc segment and the seventh oblique line segment, and the connection between the eighth arc segment and the ninth oblique line segment smoother and more convenient for processing.

[0017] 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.

[0018] like Figure 1 , Figure 2 A lightweight disc brake caliper body is shown, comprising

[0019] A caliper body, the caliper body includes a box docking section 1, a bridge docking section 2 and an intermediate connecting section connecting the box docking section 1 and the bridge docking section 2. The box docking section 1, the bridge docking section 2 and the intermediate connecting section together form a square-shaped opening 4 for installing the brake lining of a disc brake.

[0020] The middle connecting section is composed of two connecting segments 3, and the connecting segments 3 are arranged tilted. The tilting direction of the connecting segments 3 is from the top of the connecting segment 3 to the bottom of the connecting segment 3 and gradually tilts away from the center direction of the U-shaped opening 4.

[0021] The connecting segment 3 has an arcuate top surface 31, an arcuate bottom surface 32, and an inner side wall and an outer side wall connecting the arcuate top surface 31 and the arcuate bottom surface 32. The diameter of the circle where the arcuate top surface 31 is located is smaller than the diameter of the circle where the arcuate bottom surface 32 is located. The diameter of the circle where the arcuate top surface 31 is located is designed to be smaller than the diameter of the circle where the arcuate bottom surface 32 is located, so that the connecting segment 3 can form a structure that is small at the top and large at the bottom, thereby making the upper part of the connecting segment 3 thinner and reducing the weight of the connecting segment 3.

[0022] The inner side wall of the connecting segment 3 includes a first oblique line segment 301, a second oblique line segment 302, a third arc segment 303 and a fourth oblique line segment 304 which are sequentially distributed from top to bottom, wherein the inclination direction of the first oblique line segment 301, the second oblique line segment 302 and the fourth oblique line segment 304 is gradually inclined from top to bottom toward the center direction away from the U-shaped opening 4, and the lengths of the fourth oblique line segment 304, the first oblique line segment 301 and the second oblique line segment 302 decrease sequentially, the first oblique line segment 301 and the second oblique line segment 302 are connected together to form a V-shaped structure, and the apex of the V-shaped structure faces the U-shaped opening 4, and the arc opening direction of the third arc segment 303 faces the U-shaped opening 4.

[0023] The outer side wall of the connecting segment 3 includes a fifth oblique line segment 305, a sixth arc segment 306, a seventh oblique line segment 307, an eighth arc segment 308, a ninth oblique line segment 309 and a tenth oblique line segment 310 which are sequentially distributed from top to bottom, wherein the inclination direction of the fifth oblique line segment 305, the seventh oblique line segment 307 and the ninth oblique line segment 309 is gradually inclined from top to bottom toward the center direction away from the U-shaped opening 4, and the inclination direction of the tenth oblique line segment 310 is gradually inclined from top to bottom toward the center direction close to the U-shaped opening 4, and the lengths of the fifth oblique line segment 305, the seventh oblique line segment 307, the tenth oblique line segment 310 and the ninth oblique line segment 309 decrease in sequence, the arc opening directions of the sixth arc segment 306 and the eighth arc segment 308 are opposite to the U-shaped opening 4, and the diameter of the circle where the sixth arc segment 306 is located and the diameter of the circle where the eighth arc segment 308 is located are both smaller than the diameter of the circle where the third arc segment 303 is located.

[0024] The sixth arc segment 306 and the seventh oblique line segment 307 are connected by an arc transition, and the eighth arc segment 308 and the ninth oblique line segment 309 are connected by an arc transition. The arc transition between the sixth arc segment 306 and the seventh oblique line segment 307, and the arc transition between the eighth arc segment 308 and the ninth oblique line segment 309 are connected by an arc transition to make the connection between the sixth arc segment 306 and the seventh oblique line segment 307, and the connection between the eighth arc segment 308 and the ninth oblique line segment 309 smoother and more convenient for processing.

[0025] The pliers structure of the utility model adopts the design of inclined connecting segment 3 by redesigning the structure of the middle connecting segment, and then cooperates with the design of arc segments and oblique segments at different positions of the connecting segment 3 itself. The strength requirement required for the bottom of the connecting segment 3 is greater than the strength requirement required for the top of the connecting segment. Therefore, the diameter of the circle where the arc top surface 31 is located is designed to be smaller than the diameter of the circle where the arc bottom surface 32 is located, and the inner and outer side surfaces of the entire connecting segment 3 are no longer designed to be a single smooth surface. Based on such a design, the position where the strength requirement of the connecting segment 3 is high is made thicker, and the other positions are made thinner. Combined with the inclined design of the two connecting segments 3, and the inclination direction of the connecting segment 3 is controlled, it can not only meet the structural requirements of the middle connecting segment, but also reduce the weight of the middle connecting segment, providing a good foundation for subsequently reducing the weight of the entire pliers body.
