Description

Technical Field

[0001] This utility model relates to a shear-resistant brake pad steel backing with a single-sided mesh lock structure, belonging to the technical field of brake pad steel backing. Background Technology

[0002] Brake pads for small and medium-sized cars generally consist of a steel backing and friction pads. The friction pads are made of reinforcing materials, adhesives, and fillers bonded together. The steel backing, made of stamped steel sheet, serves to bear and support the friction pads. During braking, the steel backing is pushed by the brake caliper, and its friction pads come into contact with and rub against the brake disc or drum, achieving the purpose of deceleration and braking through friction. Since brake pads are the most critical safety component in a car's braking system, the effectiveness of braking depends entirely on them. Therefore, the bonding strength between the steel backing and the friction material, as well as the strength of the steel backing, are important factors.

[0003] Chinese Patent Publication No. (CN 210068804 U) discloses a brake pad steel backing, comprising a steel backing body with several boat-shaped protrusions on it. Each boat-shaped protrusion is formed by partially cutting and folding upwards on the steel backing body; grooves are formed where the steel backing body is cut and folded upwards. In this invention, the boat-shaped protrusions are directly formed by folding upwards on the steel backing body, resulting in a strong connection, preventing detachment, and exhibiting high shear strength. The boat-shaped protrusions are boat-shaped, providing high structural strength and ease of processing. By inserting a cutting tool into the steel backing body and prying it up, a portion of the steel backing body can be folded upwards to form the boat-shaped protrusions, significantly improving production efficiency.

[0004] However, the friction pads and the steel backing are firmly bonded together with adhesive. However, when the brake pads need to be replaced due to wear, even though the steel backing is still in good condition, it cannot be removed from the friction pads. Therefore, users cannot replace the worn friction pads separately and must replace the entire brake pad assembly. This undoubtedly increases the replacement cost and may cause unnecessary waste of resources.

[0005] To address this, a shear-resistant brake pad steel backing with a single-sided mesh lock structure is proposed. Utility Model Content

[0006] In view of this, the present invention provides a shear-resistant brake pad steel backing with a single-sided mesh lock structure to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1-6As shown, this utility model embodiment provides a single-sided mesh lock structure anti-shear brake pad steel back 103, including: a replacement assembly, which includes a retaining spring 101, a silencing plate 102, and a steel back 103, wherein the rear side of the silencing plate 102 is fixedly connected to the front side of the steel back 103, and the rear side of the retaining spring 101 is fixedly connected to the front side of the silencing plate 102; and an anti-shear assembly, which includes a plug-in plate 201, a frame ring 202, and a fixing plate 203, wherein the front side of the plug-in plate 201 is fixedly connected to the rear side of the steel back 103, the rear side of the frame ring 202 is fixedly connected to the front side of the fixing plate 203, and the rear side of the plug-in plate 201 is movably connected to the inside of the frame ring 202.

[0032] When assembling or replacing the steel back 103, the connecting plate is inserted into the frame ring 202. When connecting and fixing the steel back 103 to the fixing plate 203, it is fixed by bolts 205 to prevent loosening during use and improve shear resistance.

[0033] Example 2

[0034] like Figure 3-6 As shown, in one embodiment, a insertion groove 204 is provided on the inner side of the frame ring 202. The rear side of the insertion plate 201 is movably connected to the interior of the insertion groove 204. A bolt 205 is movably connected to the front side of the steel back 103. The rear side of the bolt 205 extends into the interior of the frame ring 202. An insertion post 206 is fixedly connected to the front side of the frame ring 202. The rear side of the bolt 205 is movably connected to the interior of the insertion post 206. An adhesive 104 is fixedly connected to the rear side of the fixing plate 203. A friction block 105 is fixedly connected to the rear side of the adhesive 104. A rotating rod 106 is provided on the front side of the steel back 103.
