Description

Technical Field

[0001] This utility model relates to the field of tires, and in particular to a polyurethane tire with a symmetrical tread pattern structure. Background Technology

[0002] Polyurethane tires are tires made primarily of polyurethane. Current polyurethane tire tread designs often fail to adequately balance grip and water drainage. In complex road conditions, such as wet or muddy surfaces, insufficient tire grip can easily lead to vehicle slippage, affecting driving safety; while poor water drainage can cause a water film to form between the tire and the ground, further reducing grip. For example, some polyurethane tires have overly simple tread designs, consisting of asymmetrical grooves. This asymmetry can lead to uneven grip on the left and right sides during driving, and also prevents the rapid drainage of water between the tire and the ground, significantly reducing vehicle handling performance on wet and slippery surfaces. Utility Model Content

[0003] The purpose of this invention is to provide a polyurethane tire with a symmetrical tread pattern structure, which improves the grip and drainage performance of existing polyurethane tires.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A polyurethane tire with a symmetrical tread pattern structure, comprising a tire carcass and a tread pattern, wherein the tread pattern is symmetrically distributed with the tire's central axis as the axis of symmetry, and the tread pattern is composed of multiple independent tread block units, each tread block unit having a rhomboid structure, and the surface of the tread block unit having multiple small grooves, the groove depth being less than the height of the tread block unit, and the symmetrically distributed tread block units forming continuous drainage channels and gripping areas on the tire surface.

[0005] Preferably, the included angle between two adjacent sides of the tread block unit is 60°-120°. Tread block units within this angle range can ensure tire grip while also taking into account tire wear resistance.

[0006] Preferably, the grooves on the surface of the tread block unit are arranged in a wave shape. The wave-shaped grooves enhance the tire's ability to drain water and remove mud and sand, further improving the tire's grip on wet and muddy roads and reducing slippage.

[0007] Preferably, the tire carcass is made of polyurethane material, and the tread pattern is integrally formed with the tire carcass. The use of polyurethane material improves the overall performance of the tire, including strength, elasticity and wear resistance, and extends the service life of the tire. The integral molding process ensures the connection strength between the tread pattern and the carcass.

[0008] Preferably, the tire tread pattern has reinforcing ribs on both sides of the axis of symmetry. The reinforcing ribs improve the strength and rigidity of the tire tread, reduce tire deformation during driving, and improve the tire's handling performance and driving stability.

[0009] Preferably, the cross-section of the reinforcing rib is semi-circular. The semi-circular cross-section of the reinforcing rib can reduce stress concentration and lower the risk of damage to the reinforcing rib itself while ensuring increased tire tread rigidity.

[0010] Preferably, the tire body has drainage grooves on both sides of the tire carcass, which are connected to the tread pattern. The drainage grooves further enhance the tire's ability to drain water and remove mud and sand, especially at the sides of the tire, which can effectively prevent water film effect and mud and sand accumulation.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. This utility model uses a symmetrical tread pattern with the tire's central axis as the axis of symmetry, which makes the force on both sides of the tire uniform during driving. When the vehicle is turning, changing lanes or driving straight, the symmetrical tread structure can ensure that the friction force between the tire and the ground is evenly distributed, avoiding problems such as driving deviation and sideslip caused by asymmetrical tread patterns, thus improving the stability of the vehicle and allowing the driver to control the vehicle's driving direction more precisely.

[0013] 2. This utility model forms a continuous gripping area on the tire surface through multiple independent and diamond-shaped tread block units. The diamond-shaped tread block units have a large contact area and good embedding ability, which can better embed into the ground and provide sufficient friction. When driving on dry roads, the tread block units are in close contact with the ground to ensure that the tire has sufficient grip, making the vehicle acceleration, braking and turning more stable.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3 This embodiment provides a polyurethane tire with a symmetrical tread pattern structure, including a tire body 1 and a tread pattern. The tread pattern is symmetrically distributed with the tire's central axis as the axis of symmetry. The tread pattern is composed of multiple independent tread block units 2. Each tread block unit 2 has a rhomboid structure. The surface of the tread block unit 2 is provided with multiple small grooves 3. The depth of the grooves 3 is less than the height of the tread block unit 2. The symmetrically distributed tread block units 2 form continuous drainage channels and gripping areas on the tire surface.

[0020] During tire rolling, because the tread pattern is symmetrically distributed with the tire's central axis as the axis of symmetry, when the tire contacts the ground, multiple independent and diamond-shaped tread block units 2 will interact with the ground. The grooves 3 on the surface of the tread block units 2 will guide water, mud and other impurities between the tire and the ground to be discharged when the tire rolls. At the same time, the symmetrically distributed tread block units 2 form continuous drainage channels and gripping areas on the tire surface, allowing the tire to better adapt to the ground conditions during driving.

[0021] The included angle between two adjacent sides of the tread block unit 2 is 60°-120°. When the tire contacts the ground and bears pressure, this tread block unit 2 with a specific angle can better disperse stress. The included angle of different angles allows the tread block unit 2 to maintain good structural stability under force in different directions. At the same time, the contact area and contact method with the ground will also be adjusted with the change of angle.

[0022] The grooves 3 on the surface 2 of the tread block unit are arranged in a wave shape. When the tire rolls, the wave-shaped grooves 3 will produce a special friction effect when they come into contact with the ground. The undulation of the wave shape can increase the contact area and friction between the grooves 3 and the impurities on the ground. At the same time, during the rolling process of the tire, the wave-shaped grooves 3 can more effectively guide water and mud and other impurities to be discharged along the grooves 3 between the tire and the ground.

[0023] The tire carcass 1 is made of polyurethane material, which has high strength, high elasticity and good wear resistance. The tread pattern is integrally formed with the tire carcass 1. During the tire manufacturing process, the tread pattern is directly bonded to the carcass through a specific process to form a whole. When the tire rolls, the integrally formed structure prevents relative displacement between the tread pattern and the carcass, allowing them to better perform their respective functions.

[0024] The tire tread pattern has reinforcing ribs 4 on both sides of the axis of symmetry. When the tire is subjected to pressure and friction, the reinforcing ribs 4 can share some of the stress and enhance the rigidity of the tire tread. The reinforcing ribs 4 and the tire tread pattern work together to enable the tire to better maintain its shape and structural stability during rolling.

[0025] The cross-section of the reinforcing rib 4 is semi-circular. When the tire rolls and contacts the ground, the semi-circular cross-section allows the reinforcing rib 4 to better distribute stress under load. The semi-circular shape enables the reinforcing rib 4 to maintain good structural stability under stress in different directions, while also providing a more reasonable contact area and stress distribution with the surrounding tire body.

[0026] The tire body 1 has guide grooves 5 on both sides of its edge. The guide grooves 5 are connected to the tread pattern. When the tire rolls, water, mud and other impurities on the ground will first enter the tread pattern and then be quickly discharged from the tire edge through the guide grooves 5, thus preventing impurities from accumulating between the tire and the ground.

[0027] 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.
