Description

Technical Field

[0001] The present invention relates to the field of automobiles, in particular to a tire balancing weight. Background Art

[0002] Balance blocks are used to be installed on the inside of the wheel hub for counterweighting. During the wheel production and installation process, due to assembly errors in the manufacturing process and other reasons, the overall mass distribution of the wheel is often uneven. When rotating at high speeds, the wheel may form a "dynamic imbalance state", seriously affecting the driving quality of the car. Therefore, it is often necessary to install balance blocks for balancing purposes.

[0003] When a wheel is punctured, it is often necessary to re-test the dynamic balance when repairing it. The original balance block needs to be disassembled and re-installed. However, when the balance block is separated, the protective layer cannot be separated accurately, causing the adhesive layer on one side to be exposed, affecting the next use of the counterweight block in that area. Therefore, a tire balance block is proposed to address the above problem. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the main purpose of the present invention is to provide a tire balance block. The pre-slotted holes in the tearing portion can ensure that the counterweight block is separated along the trajectory of the tearing portion, ensure the precise separation of the protective layer, and ensure the subsequent use of the counterweight block on one side.

[0005] To achieve the above object, the present invention adopts the following technical solution: a tire balancing weight, comprising a bonding layer bonded to one side of each balancing weight, and a protective layer provided on the other end surface of the bonding layer;

[0006] A plurality of tearing portions are arranged on the surface of the protection layer.

[0007] Preferably, the counterweight is made of iron.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] Multiple tearing parts are provided on one side of the protective layer. The tearing parts are provided with multiple pre-slotted holes and are located between the counterweight blocks. When removing the counterweight blocks, the pre-slotted holes in the tearing parts can ensure that the counterweight blocks are separated along the trajectory of the tearing parts, ensuring the precise separation of the protective layer and ensuring the subsequent use of the counterweight blocks on one side.

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0014] Example

[0015] Tire balance weights, such as Figure 1 As shown, it includes several groups of counterweight blocks 1 arranged side by side;

[0016] One side of each counterweight 1 is bonded with an adhesive layer 2, and the other end surface of the adhesive layer 2 is provided with a protective layer 3;

[0017] A plurality of tearing portions 4 are provided on the surface of the protective layer 3 .

[0018] The counterweight 1 is made of iron

[0019] When a wheel is punctured, it is often necessary to re-test the dynamic balance when repairing it. The original balance block needs to be disassembled and re-installed. When the balance block is separated, the protective layer cannot be separated accurately, resulting in the exposure of the adhesive layer on one side, affecting the next use of the counterweight block in that area. A plurality of tearing parts 4 are provided on one side of the protective layer 3. The tearing part 4 is provided with a plurality of pre-slotted holes and is located between the counterweight blocks 1. When removing the counterweight block 1, the pre-slotted holes of the tearing part 4 can ensure that the counterweight block 1 is separated along the trajectory of the tearing part 4, ensuring the accurate separation of the protective layer 3 and ensuring the subsequent use of the counterweight block 1 on one side.

[0020] Finally, it should be noted that the embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
