Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, specifically to an automotive brake caliper. Background Technology

[0002] The braking operation of a car is completed by the cooperation of the brake disc and the brake caliper. During the braking process, the brake caliper is mostly controlled by a hydraulic cylinder. The hydraulic pressure of the hydraulic oil causes the piston rod to move the friction pads installed in the brake caliper body closer to the brake disc. The friction between the brake friction pads and the brake disc reduces the rotation speed of the brake disc, thereby achieving the braking effect. For safety reasons, it is usually equipped with a housing to limit the position of the brake disc and also to protect the brake disc. Since both rely on friction braking.

[0003] As friction continues, the gap will continue to increase. During maintenance and repair, it is difficult to observe the internal wear condition without disassembling the casing. When the wear is too great and is not detected in time, it will affect the safety of subsequent use. Reassembly after maintenance is relatively inconvenient and wastes a lot of time. At the same time, the heat generated by friction is not easily dissipated due to the casing, which can easily affect its service life. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automotive brake caliper that can effectively solve the problems of heat generated by friction due to the enclosure of the housing and the inconvenience caused by reassembly in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an automotive brake caliper, including a caliper body. A square groove is formed in the middle of the caliper body, and two sets of sliding rods are fixed in the square groove. A friction mounting assembly is sleeved on the outer side of the sliding rods. The friction mounting assembly includes two sets of mounting plates and friction pads fixed to the inner edge of the mounting plates. A connecting hole is formed at the top of the mounting plate, and a central rod is fixed in one of the connecting holes. Anti-slip nuts are sleeved on both sides of the central rod. A fastening block is fixed at the top of the caliper body, and the anti-slip nuts are located on the outer side of the fastening block.

[0008] Furthermore, the mounting plate and friction pad are arc-shaped structures, and the connecting hole is arc-shaped on the mounting plate.

[0009] Furthermore, a fastening nut is fixed to the outside of the connection hole of each set of mounting plates.

[0010] Furthermore, a hydraulic pipe is provided at the tail end of the caliper body, with one end of the hydraulic pipe connected to the oil inlet and the other end connected to two sets of mounting friction components.

[0011] Furthermore, the bottom end of the friction pad has an outwardly curved arc structure.

[0012] Furthermore, the connecting holes on both sides of the top of the mounting plates are square in shape and their size is larger than that of the slide rod.

[0013] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0014] This utility model features a square groove structure in the middle of the caliper body, which is part of a mounting friction assembly. This groove structure allows for observation of the mounting friction assembly's usage status, heat dissipation of the high temperatures generated by internal friction, and reduction of the caliper body's weight. In the mounting friction assembly, the arc-shaped mounting plate and friction pad structure are fitted onto the fastening block structure of the caliper body via the top central rod, and finally secured by the outer anti-slip nut. Hydraulic drive is achieved through the inner hydraulic pipe. The arc-shaped square groove structure facilitates contact and friction with external structures.

[0015] In this device, the mounting friction assembly is connected and fixed to the fastening block structure on the caliper body through the central rod structure, and is sleeved by the sliding rod in the square groove. Therefore, the sliding rod structure on both sides can slide assistedly during movement. The central rod and the mounting plate are fixedly connected by the anti-slip nut, which facilitates direct fixed connection and reduces installation steps. Attached Figure Description
