Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a high friction-resistant and corrosion-resistant automotive transmission belt. Background Technology

[0002] The reliability of drive belts is ensured by their abrasion resistance and corrosion resistance. Automotive drive belts must have high durability and stability.

[0003] A search revealed existing technology (application number: CN108843771B), which describes a "one-way device that reduces the resonant frequency through axial movement adjustment." This utility model is a pulley structure that absorbs impact energy through axial floating functionality.

[0004] However, while existing technologies reduce resonant frequency and alleviate belt fatigue, they still have some shortcomings: the solution mainly focuses on improving the pulley, without involving the optimization of belt body material or surface treatment process, and has limitations in dealing with friction and wear and chemical media corrosion, making it difficult to comprehensively prevent problems such as slippage, delamination and cracking. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-friction-resistant and corrosion-resistant automotive transmission belt.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high friction-resistant and corrosion-resistant automotive transmission belt, comprising a transmission belt body and a drive wheel, wherein the transmission belt body is sleeved on the drive wheel and is used to drive the transmission belt body to move by means of friction.

[0007] As a further description of the above technical solution:

[0008] The transmission belt body contains four layers: a wear-resistant layer, a base layer, an anti-corrosion layer, and a reinforcement layer.

[0009] As a further description of the above technical solution:

[0010] The transmission belt body includes a wear-resistant layer, which is disposed on the outermost layer of the transmission belt body and is made of modified polytetrafluoroethylene (PTFE) material. The surface is provided with multiple raised particles to reduce the direct friction area between the transmission belt body and the external environment.

[0011] As a further description of the above technical solution:

[0012] The base layer, the wear-resistant layer covering the outer surface of the base layer, is made of high-strength rubber material, its thickness is uniformly distributed and its surface is microporous, and multiple grooves are opened on the inner side at intervals along the circumference.

[0013] As a further description of the above technical solution:

[0014] The anti-corrosion layer, located on the inner surface of the substrate layer, extends circumferentially and is fixed to the substrate layer by an adhesive, and is made of epoxy resin and nano zinc oxide composite material.

[0015] As a further description of the above technical solution:

[0016] The reinforcing layer, embedded inside the base layer, extends laterally and is bonded to the base layer through a hot-pressing process. It is woven from multiple strands of aramid fibers and coated with a polyurethane coating on its outer surface.

[0017] As a further description of the above technical solution:

[0018] The raised particles of the wear-resistant layer are fixed to the outer surface of the base layer by injection molding, and each particle has an annular groove at its bottom.

[0019] This utility model has the following beneficial effects:

[0020] 1. Achieving comprehensive wear resistance upgrade through "material innovation + surface structuring"; the outermost wear-resistant layer uses modified PTFE material, and the surface raised particle design reduces the actual contact area with the drive wheel, thus reducing the slippage rate compared to ordinary rubber belts; the microporous treatment of the matrix layer and the circumferential groove form an "elastic meshing" structure, which maintains contact stability when transmitting high tensile force. Combined with the aramid fiber weaving reinforcement of the reinforcing layer, the fatigue life is improved, and the problem of belt surface peeling caused by friction is completely solved.

[0021] 2. By innovatively constructing a three-tiered anti-corrosion barrier of "surface isolation - body protection - core reinforcement": the epoxy resin and nano zinc oxide composite material of the anti-corrosion layer can block most of the penetration of engine oil and coolant, improving the efficiency of chemical erosion protection against the base layer; the polyurethane coating of the reinforcement layer forms secondary protection, improving the strength retention rate of the internal aramid fibers in oily environments; the multi-layer structure achieves molecular-level bonding through hot pressing process, improving the interlayer peel strength, and preventing cracking and delamination under extreme working conditions, solving the functional failure problem of traditional belts caused by chemical corrosion, extending the overall service life compared to conventional products, and significantly reducing vehicle operation and maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a high friction-resistant and corrosion-resistant automotive transmission belt, including: a transmission belt body 2; a drive wheel 1, wherein the transmission belt body 2 is sleeved on the drive wheel 1 and is used to drive the transmission belt body 2 to move by means of friction.

[0031] In this embodiment, the main body of the transmission belt constitutes a high friction-resistant and corrosion-resistant automotive transmission belt as described in this application.

[0032] It should also be noted that the vehicle drive belt in this application can be used with this device as long as it is a vehicle belt that needs to transmit power, and this application does not limit the specific vehicle type.

[0033] Specifically, the transmission belt body 2 contains four layers: a wear-resistant layer 3, a base layer 4, an anti-corrosion layer 5, and a reinforcing layer 6.

[0034] In this embodiment, the four-layer structure works together to perform wear resistance, support, corrosion prevention, and reinforcement functions, thereby improving the overall performance of the transmission belt and meeting the requirements for friction resistance and corrosion resistance.

[0035] Specifically, the transmission belt body 2 includes a wear-resistant layer 3, which is disposed on the outermost layer of the transmission belt body 2 and is made of modified polytetrafluoroethylene (PTFE) material. The surface is provided with multiple protruding particles to reduce the direct friction area between the transmission belt body 2 and the external contact surface.

[0036] As a preferred embodiment, the diameter of each particle is 0.5mm to 1mm, and the spacing between particles is 2mm to 3mm. The raised particles reduce the direct friction area with the outside world, and the modified PTFE material itself is friction-resistant, reducing the wear rate, improving the wear resistance of the transmission belt surface, and extending the service life.

[0037] Example 2:

[0038] Based on Example 1, in order to further improve transmission efficiency, a base layer 4 is arranged inside the transmission belt body 2;

[0039] Specifically, the base layer 4, the wear-resistant layer 3 covers the outer surface of the base layer 4, is made of high-strength rubber material, its thickness is uniformly distributed and its surface is microporous, and multiple grooves are opened on the inner side at intervals along the circumference.

[0040] In this embodiment, the depth to width ratio of each groove is 1:2; high-strength rubber provides structural support, microporous treatment enhances the bonding force with the wear-resistant layer 3, the grooves enhance the meshing performance with the drive wheel 1, ensuring the overall structural stability of the transmission belt and improving the transmission efficiency with the drive wheel.

[0041] Specifically, the anti-corrosion layer 5 is disposed on the inner surface of the substrate layer 4, extends circumferentially and is fixed to the substrate layer 4 by an adhesive, and is made of epoxy resin and nano zinc oxide composite material.

[0042] With this configuration, the thickness of the anti-corrosion layer 5 is 0.2mm to 0.5mm; the composite material blocks the penetration of chemical media such as engine oil and coolant, avoids erosion of the base layer 4, improves the corrosion resistance of the transmission belt, and prevents chemical media from damaging the base.

[0043] Example 3:

[0044] Based on Example 2, in order to further improve transmission efficiency, a reinforcing layer 6 is arranged inside the transmission belt body 2;

[0045] Specifically, the reinforcing layer 6 is embedded inside the base layer 4, extends laterally and is bonded to the base layer 4 by a hot pressing process. It is woven from multiple strands of aramid fibers and has a polyurethane coating on its outer surface.

[0046] The diameter of each fiber is 0.2mm to 0.5mm, and the weaving angle is 45° to 60°; the thickness of the polyurethane coating is 0.1mm to 0.3mm; the aramid fiber improves the tensile strength and fatigue resistance, and the polyurethane coating isolates the external chemical media from corrosion, enhances the overall strength of the transmission belt, and improves fatigue resistance and corrosion resistance.

[0047] Specifically, the raised particles of the wear-resistant layer 3 are fixed to the outer surface of the base layer 4 by injection molding, and each particle has an annular groove at its bottom.

[0048] In this embodiment, the width of the annular groove is 0.2mm to 0.3mm and the depth is 0.1mm to 0.2mm. The annular groove increases the contact area and bonding force between the particles and the substrate layer 4, prevents the particles from falling off, ensures the firmness of the protruding particles, and maintains the wear resistance effect of the wear-resistant layer.

[0049] In actual use, when the drive wheel 1 rotates, it relies on the friction between itself and the transmission belt body 2 to drive the transmission belt body 2, thereby realizing the transmission of power between different components. During the operation of the transmission belt body 2, the outermost wear-resistant layer 3 plays a key role. It is made of modified polytetrafluoroethylene (PTFE) material, and the raised particles on the surface reduce the direct friction area with the external contact surface, reducing the wear rate. At the same time, the annular grooves at the bottom of the particles increase the bonding strength with the base layer 4, preventing the particles from falling off. The base layer 4 is made of high-strength rubber material. The belt is uniform in thickness and has a microporous surface. The grooves on the inner side enhance the meshing performance with the drive wheel 1, ensuring the stability of power transmission. The anti-corrosion layer 5 is located on the inner surface of the base layer 4 and is made of epoxy resin and nano zinc oxide composite material. It effectively blocks the penetration of chemical media such as engine oil and coolant, protecting the base layer 4 from corrosion. The reinforcement layer 6 is embedded inside the base layer 4. Multiple strands of aramid fibers improve the overall tensile strength and fatigue resistance of the belt. The polyurethane coating on the outer surface isolates the reinforcement layer 6 from the corrosion of external chemical media, further ensuring the service life and performance of the belt.

[0050] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power.

The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
