Description

Technical Field

[0001] This utility model relates to the field of tires, and in particular to a tire for a tireless, ride-on lawnmower. Background Technology

[0002] In the field of low-speed machinery, such as ride-on lawnmowers used for weeding, lawns may contain various sharp objects, such as small stones and thorns. Ordinary pneumatic tires are easily punctured by these objects, causing leaks and affecting the lawnmower's normal operation. Therefore, the demand for pneumatic tires has emerged. Currently, pneumatic tires on the market fall into two categories: one is almost entirely solid tires, which are very heavy and lack elasticity, resulting in a poor user experience; the other is Michelin's TWEEL tire, which uses many expensive new materials. Because the rim, tire support frame, and tread materials are different, the installation process is also very complex, ultimately leading to a high price that makes it unsuitable for widespread adoption. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tire for a non-pneumatic riding lawnmower. This tire has a simple structure and uses very mature materials. Its tread strength is greatly enhanced due to the embedding of highly elastic materials, and the elastic modulus is increased, resulting in better tire durability and comfort.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pneumatic, ride-on lawnmower tire, comprising a hollow tire body, the tire body comprising a sidewall and a tread, a highly elastic material embedded below the tread, the highly elastic material covering the central area of ​​the tread, the area of ​​which accounts for more than half of the tread area.

[0005] Furthermore, the highly elastic material is made of steel wire rings, which are arranged side by side.

[0006] Furthermore, the wire ring is provided with multiple layers.

[0007] Furthermore, when the wire coils are arranged, the spacing between the wire coils in the central region is less than or equal to the spacing between the wire coils in the two side regions.

[0008] Furthermore, the wire ring has at least two layers in the central region and one layer in the two side regions.

[0009] Furthermore, the high-elasticity material has one or more layers of fabric on its upper or lower side.

[0010] Furthermore, the distance between the highly elastic material and the root of the tread pattern is 5-10 mm.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This pneumatic tire has a simple structure. Its tread strength is greatly enhanced due to the embedding of highly elastic materials, and the elastic modulus is increased, which makes the tire more durable and comfortable, and can resist punctures from sharp objects.

[0013] 2. The high-elasticity material uses steel wire rings, which are inexpensive and have extremely high tensile strength, which can significantly enhance the structural strength of the tire bead. This makes the bead area less prone to deformation or damage when the tire is subjected to high loads and high pressures.

[0014] 3. By distributing the steel wire rings in a way that they are denser in the central area and sparser on both sides, the tire's overall deformation resistance can be reduced without affecting its production cost. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 2 The tire shown is a pneumatic, ride-on lawnmower tire, which includes a hollow tire body 1. The tire body 1 includes a sidewall 2 and a tread 3. A highly elastic material is embedded under the tread 3, and the highly elastic material covers the central area of ​​the tread 3, with its area accounting for more than half of the area of ​​the tread 3.

[0020] The process of using this invention is as follows: Since the tire body 1 includes a sidewall 2 and a tread 3, with the tread 3 being a relatively weak area, a highly elastic material is embedded beneath the tread 3. This material mainly covers the central area of ​​the tread 3, and its area needs to occupy more than half of the tread 3's area. This effectively enhances the overall strength of the tread 3, extending its lifespan. Simultaneously, embedding the highly elastic material beneath the tread 3 effectively enhances the tire's structural strength and dimensional stability, allowing the tire to maintain a better shape during driving, reducing vibration and instability caused by tire deformation, and ensuring the tire maintains a perfect roundness, thus improving riding comfort. Especially for lawnmower tires, because lawn soil is relatively soft, embedding the highly elastic material beneath the tread 3 significantly enhances the tire's structural stability and increases its elastic modulus, allowing the tire to maintain a better shape under complex road conditions such as mud. This stability reduces tire deformation during driving, thereby reducing vibration and instability caused by tire deformation and improving comfort.

[0021] Furthermore, the high-elasticity material uses steel wire rings 4, which are arranged side by side. Specifically, the high-elasticity material of this invention uses steel wire rings 4, and the steel wires have extremely high tensile strength, which can significantly enhance the structural strength of the tire bead. This makes the bead area less prone to deformation or damage when the tire is subjected to high loads and high pressures. In addition, the high-elasticity material can also be PET alloy or PBT alloy.

[0022] Furthermore, the steel wire ring 4 is provided with multiple layers. Specifically, in order to further increase the strength of the tread 3, the steel wire ring 4 is provided with multiple layers to improve its support.

[0023] Furthermore, when the steel wire rings 4 are arranged, the spacing between the steel wire rings 4 in the central region 6 is smaller than the spacing between the steel wire rings 4 in the two side regions 7. Since the central region 6 of the tire bears the greatest pressure, the spacing between its steel wire rings 4 is set to be the smallest, while the spacing between the steel wire rings 4 on both sides can be gradually increased, effectively saving the number of steel rings used, thereby reducing the tire production cost.

[0024] Furthermore, the wire ring 4 has at least two layers in the central region 6 and one layer in each of the side regions 7. Specifically, the wire ring 4 of this invention has multiple layers in the central region 6, such as... Figure 1 It is set to have three layers. One layer can be set on each side. Since the central area 6 of the tire bears the pressure, the number of layers is set to two or more, while the two sides are set to one layer to further optimize costs.

[0025] Furthermore, one or more layers of cord fabric 5 are provided on the upper or lower side of the highly elastic material. When the vehicle encounters potholes during driving, the steel wires and cord fabric work together to resist the impact force. The steel wires prevent the tire from being punctured, while the cord fabric acts as a buffer and disperses the force, thereby enhancing the overall strength of the tire. In addition, during the tire deformation and recovery process, the cord fabric can effectively constrain the position of the steel wires, reducing local displacement of the steel wires, thus making the connection of the steel wires more stable and firm.

[0026] Furthermore, the distance between the high-elasticity material and the root of the tread pattern 3 is 5-10mm. In this invention, embedding the high-elasticity material too deeply may increase the difficulty and cost of tire production, while embedding it too shallowly may reduce the stability and durability of the tire. Practice has shown that a distance of 5-10mm between the high-elasticity material and the root of the tread pattern 3 is more appropriate.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
