Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly technology and relates to an integrated structure of brake pad compression spring. Background Technology

[0002] As a key friction component in the braking system, brake pads directly affect the braking effect, driving safety, and service life of vehicles or machinery. Existing brake pads typically consist of a friction material layer bonded to a load-bearing plate via adhesive or mechanical fastening. Independent compression springs, locating pins, or clamping devices secure the brake pads to the brake caliper or brake shoe seat, ensuring positional stability, uniform force distribution, and necessary return-to-position function of the friction pair during braking. This traditional structure is widely used in automotive, construction machinery, and industrial braking systems, but it also reveals several shortcomings.

[0003] Chinese utility model patent CN207673756U, authorized by the Ministry of Industry and Information Technology, includes a brake pad body, a fixing ring, a friction block, and a spring retainer. The fixing ring includes a first fixing ring and a second fixing ring, and the spring retainer includes a first spring retainer and a second spring retainer. The first spring retainer, the first fixing ring, the second fixing ring, and the second spring retainer are sequentially arranged on the side of the brake pad body. The key feature is that the brake pad body has an opening, and the friction block is fixedly inserted into the opening. This utility model avoids changes in the brake pad material formula. By drilling a hole in the brake pad body and changing the structure of the friction block to allow it to be inserted into the brake pad body, it not only meets the requirements for lightweighting while ensuring the safety and performance of the brake pad itself, but also effectively insulates heat, reduces brake aging, increases the adhesion between the brake pad and the steel plate, and makes the brake pad less likely to fall off. The brake pads in the aforementioned prior art require the fixed installation of compression springs. The traditional common installation method is to combine two components, compression springs and fixing clips, and then weld them into the final shape. The installation of the two components is difficult, and they need to be welded together to form the shape, resulting in low production efficiency and high production costs. Utility Model Content

[0004] To address the aforementioned problems of difficult installation, the need for welding to form the brake pad, low production efficiency, and high production costs, this utility model proposes an integrated brake pad and spring structure, which effectively solves the problems of difficult installation, the need for welding to form the brake pad, low production efficiency, and high production costs in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated brake pad compression spring structure, comprising a compression spring disposed on the brake pad, wherein a fixing buckle is integrally formed on the rear end of the lower side of the compression spring, the center line of the fixing buckle and the center line of the compression spring are located in the same plane, a compression spring hook hole is provided on the brake pad, and the front end of the fixing buckle is inserted into the compression spring hook hole.

[0006] Furthermore, the front end of the fixing buckle bends upward to contact the front side of the compression spring hook hole.

[0007] Furthermore, two fixing holes are symmetrically opened at the left and right ends of the compression spring, and compression spring baffles inserted into the fixing holes are symmetrically arranged at the left and right ends of the upper side of the brake pad.

[0008] Furthermore, the compression spring is made of flexible steel.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This utility model integrates the compression spring and the fixing buckle into one piece, eliminating the need to manufacture two parts and then weld them together. This reduces the manufacturing and installation processes, significantly improves the production efficiency of the compression spring, and lowers its production cost. This invention improves the connection strength between the compression spring and the brake pad by using a bent fixing buckle and fixing hole, ensuring the reliability and stability of the compression spring during use. At the same time, it improves the convenience of installing the compression spring on the brake pad and increases the installation efficiency of the workers. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0013] like Figures 1 to 2 As shown, a brake pad compression spring integrated structure includes a compression spring 2 disposed on a brake pad 1. A fixing buckle 202 is integrally formed on the rear end of the lower side of the compression spring 2. The center line of the fixing buckle 202 and the center line of the compression spring 2 are located in the same plane. A compression spring hook hole 102 is provided on the brake pad 1, and the front end of the fixing buckle 202 is inserted into the compression spring hook hole 102.

[0014] In this embodiment, the front end of the fixing buckle 202 is bent upward and contacts the front side of the compression spring hook hole 102; When in use, the curved spring hook hole 102 allows the fixing buckle 202 to hook onto the brake pad 1, further improving the connection strength between the spring 2 and the brake pad 1 and ensuring the reliability of the spring 2 during use.

[0015] In this embodiment, the compression spring 2 has two fixing holes 201 symmetrically opened at its left and right ends, and the brake pad 1 has compression spring baffles 101 symmetrically arranged at its left and right ends on its upper side, which are inserted into the fixing holes 201. When in use, the fixing hole 201 and the spring retainer 101 can fix and position the left and right ends of the spring 2, ensuring the stability of the spring 2 during use and improving the ease of installation of the spring 2.

[0016] In this embodiment, the compression spring 2 is made of flexible steel.

[0017] In the above embodiment, the compression spring 2 is integrally cast and then polished to complete the finished product. There is no need to manufacture two parts and then weld them together, which reduces the manufacturing process and installation process, greatly improves the production efficiency of the compression spring 2, and reduces the production cost of the compression spring 2. After production is completed, the installer first hooks the fixing buckle 202 on the lower side of the compression spring 2 into the compression spring hook hole 102 of the brake pad 1 to install and fix the compression spring 2 for the first time. Since the compression spring 2 is made of flexible steel, the installer can lift both ends of the compression spring 2 and push the compression spring 2 so that the fixing holes 201 at both ends of the compression spring 2 are inserted into the compression spring baffle 101 of the brake pad 1, thereby realizing the secondary fixation of the compression spring 2 and ensuring the reliability and stability of the compression spring 2 during use.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
