Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a brake spring. Background Technology

[0002] Brake springs are an important component of the braking system. Their main functions are to fix the brake pads, ensure close contact between the brake pads and the brake disc, provide a return function, and indicate brake pad wear.

[0003] The connection structure between the common brake spring and the brake pad is relatively simple. In actual use, the spring is prone to rotation and displacement due to external forces such as vibration, which can cause the connection with the brake pad to loosen, resulting in reduced braking efficiency and insufficient practicality. Therefore, we propose a brake spring. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Common brake springs and brake pads have relatively simple connection structures. In actual use, the springs are prone to rotation and displacement due to external forces such as vibration, which can loosen the connection with the brake pads, resulting in reduced braking efficiency and insufficient practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A brake spring sheet includes a spring sheet body, and clamping assemblies are symmetrically installed on the left and right sides of the spring sheet body;

[0007] The top of the spring sheet body has symmetrical fixing blocks welded on the left and right sides near the front and back sides, and the outer side of the fixing blocks has threaded openings.

[0008] The clamping assembly includes a clamping plate, and connectors are symmetrically welded to the top of the clamping plate near the left and right sides. A fixing rod is threaded through the outer side of the connector and threaded through the inner side. A buffer spring is sleeved around the fixing rod.

[0009] As a preferred embodiment of this utility model, the spring sheet body is made of titanium alloy and its surface is processed by nickel plating.

[0010] The technical effects of adopting the above-mentioned further solutions are: titanium alloy has high hardness and extremely high metal memory, and when combined with nickel plating, it can further improve wear resistance and corrosion resistance, thereby increasing the service life of the spring sheet body.

[0011] As a preferred embodiment of this utility model, the spring sheet body is bonded with a first anti-slip pad.

[0012] The technical effect of adopting the above-mentioned further solution is that the first anti-slip pad can increase the friction between the spring plate body and the brake pad, thereby preventing the brake pad from shifting.

[0013] As a preferred embodiment of this utility model, fixing holes are provided on the left and right sides of the top of the spring sheet body, penetrating the front and other sides.

[0014] The technical effect of adopting the above-mentioned further solution is that, by using the fixing holes, bolts can be used to pass through the brake pads on both sides to initially fix the brake pads and the spring body, thereby improving ease of use.

[0015] As a preferred embodiment of this utility model, the clamping plate is made of aluminum alloy.

[0016] The technical advantages of adopting the above-mentioned further solutions are: aluminum alloy has high hardness and light weight, which can fix the brake pads without affecting the operating load of the spring plate body, thus improving practicality.

[0017] As a preferred embodiment of this utility model, a second anti-slip pad is adhered to the inner side of the clamping plate.

[0018] The technical effect of adopting the above-mentioned further solution is that the friction between the brake pad and the clamping plate can be increased by the second anti-slip pad, which in turn works with the spring plate body to clamp the brake pad, prevents loosening, and improves the stability of use.

[0019] As a preferred embodiment of this utility model, the connector is welded at an angle to the top of the clamping plate.

[0020] The technical effect of adopting the above-mentioned further solution is that by welding the connector and the clamp plate at an angle, the outer side of the connector can fit more closely with the end of the fixing rod nut, thereby facilitating the rotation of the fixing rod and improving ease of use.

[0021] As a preferred embodiment of this utility model, the fixing rod is threadedly connected to the threaded port, and the two ends of the buffer spring abut against the fixing block and the connecting piece, respectively.

[0022] The technical effect of adopting the above-mentioned further solution is that by rotating the fixing rod, the clamping plate can be moved inward, thereby cooperating with the spring plate body to clamp and fix the brake pad. The buffer spring can buffer the clamping force and prevent the fixing rod from rotating excessively, which would cause deformation of the clamping plate or the spring plate body.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In this invention, the design of the spring plate body and the clamping assembly allows the brake pad to be placed between the spring plate body and the clamping plate. By rotating the fixing rod, the clamping plate can be moved closer to the spring plate body, thereby clamping the brake pad. In addition, the first and second anti-slip pads increase the membrane friction between the brake pad and the clamping assembly, which greatly improves the fixing effect of the brake pad and prevents it from loosening or shifting, thus effectively improving its practicality.

[0034] Example 1

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a brake spring, including a spring body 1, with clamping components 2 symmetrically installed on the left and right sides of the spring body 1, and fixing blocks 101 symmetrically welded on the left and right sides of the top of the spring body 1 near the front and back, with threaded openings 102 on the outer side of the fixing blocks 101, the clamping components 2 including a clamping plate 201, with connecting parts 202 symmetrically welded on the top of the clamping plate 201 near the left and right sides, and a fixing rod 203 threaded through the outer side of the connecting part 202 and threaded onto the inner side, and a buffer spring 204 sleeved around the fixing rod 203.

[0036] Example 2

[0037] like Figure 1-4As shown, the spring plate body 1 is made of titanium alloy and its surface is processed with nickel plating. Titanium alloy has high hardness and extremely high metal memory. Combined with nickel plating, it can further improve wear resistance and corrosion resistance, thereby increasing the service life of the spring plate body 1. The spring plate body 1 is bonded with a first anti-slip pad 103, which can increase the friction between the spring plate body 1 and the brake pad, thereby preventing the brake pad from shifting. Fixing holes 104 are opened on the left and right sides of the top of the spring plate body 1, penetrating the front and other sides. Through the use of fixing holes 104, bolts can be used to pass through the brake pads on both sides to initially fix the brake pads to the spring plate body 1, improving the convenience of use. The clamping plate 201 is made of aluminum alloy. Aluminum alloy has high hardness and light weight. It can fix the brake pad without affecting the operating load of the spring plate body 1, improving practicality. The inner side of the clamping plate 201 is bonded with A second anti-slip pad 2011 is attached, which increases the friction between the brake pad and the clamping plate 201, thereby clamping the brake pad with the spring plate body 1 to prevent loosening and improve stability. The connecting piece 202 is inclinedly welded to the top of the clamping plate 201. This inclined welding allows the outer side of the connecting piece 202 to fit more closely with the nut end of the fixing rod 203, facilitating the rotation of the fixing rod 203 and improving ease of use. The fixing rod 203 is threadedly connected to the threaded port 102. The two ends of the buffer spring 204 abut against the fixing block 101 and the connecting piece 202, respectively. Rotating the fixing rod 203 can move the clamping plate 201 inward, thereby clamping and fixing the brake pad with the spring plate body 1. The buffer spring 204 can buffer the clamping force to prevent the fixing rod 203 from rotating excessively, which could cause deformation of the clamping plate 201 or the spring plate body 1.

[0038] The working process of this utility model is as follows: When assembling and using a brake spring, the brake pad is first placed on the periphery of the spring body 1, and bolts are used to pass through the fixing holes 104 on both sides of the brake pad to initially fix the brake pad between the spring body 1. The fixing rod 203 is rotated to move the clamping plate 201 inward, thereby clamping the brake pad with the spring body 1. The first anti-slip pad 103 and the second anti-slip pad 2011 increase the membrane friction between the brake pad and the first anti-slip pad 103, thereby fixing and reinforcing the brake pad, greatly improving the fixing effect of the brake pad, preventing it from loosening or shifting, and effectively improving its practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
