Description

Technical Field

[0001] The utility model belongs to the technical field of automobile tires, and particularly relates to a new type of new energy vehicle tire. Background Art

[0002] China's national standard stipulates that the tread wear limit of radial tires for cars is 1.6 mm, and the tread wear limit of radial tires for trucks and buses is 2.0 mm. It also requires tire manufacturers to compulsorily set tread wear indicators (TWI) on tires according to the standard. When the tire tread wears to the above limits, it reminds the driver to replace the tire in time. The tread wear indicator provides a criterion for judging the wear condition of the tread pattern blocks, but there are also certain defects in practicality. For example: 1. The indicator can only indicate when the tread wears to the limit and cannot directly reflect the real-time wear condition of the tire; 2. It is inconvenient to measure, requires certain professional tools and skills, and is prone to errors; 3. When the tire wears to a certain extent, its performance begins to decline and there is no reminder function; 4. The tread pattern on the tire is prone to getting stuck with stones, gravel and other sundries, which will accelerate the wear of the tire. After a long time, the pattern at the place where the stones and gravel are stuck will be damaged and deformed, and the wear indicator cannot show the overall and local wear conditions of the tire. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a new type of new energy vehicle tire. By arranging multiple layers of transverse protrusions in the tread pattern grooves of the tire, the overall wear condition of the tire can be visually shown, and the partial wear condition of the tire can also be visually shown. At the same time, it is beneficial to avoid getting stuck with stones, gravel and other sundries in the pattern grooves. Even if stones, gravel and other sundries are stuck, the position where the stones and gravel are stuck can be judged in time through the serious local wear condition, and the stones and gravel can be removed, and it is also beneficial to reduce noise.

[0004] The technical solution of the utility model is as follows:

[0005] A new type of new energy vehicle tire, including a tire body, a wear indicator is arranged on the tire body, the wear indicator is arranged at the bottom of the tread pattern groove, multiple layers of transverse protrusions are arranged on both sides of the tread pattern groove, each layer of transverse protrusion is distributed along the circumferential direction of the tire with the center of the tire as the center, the outermost layer of transverse protrusion is flush with the tread, and the innermost layer of transverse protrusion is flush with the height of the wear indicator.

[0006] Preferably, the distance between the outermost layer of transverse protrusions opposite to each other on both sides of the pattern groove is less than the distance between the innermost layer of transverse protrusions opposite to each other.

[0007] Further preferably, the sum of the lengths of the innermost layer of transverse protrusions arranged on both sides of the tread pattern groove is less than the length of the wear indicator.

[0008] Further preferably, the distance between the opposite lateral protrusions on both sides of the tread groove gradually decreases from the outermost layer to the innermost layer.

[0009] Further preferably, the distance between the opposite lateral protrusions on both sides of the tread groove first decreases, then increases, and then decreases again from the outermost layer to the innermost layer, cycling in this way. In this way, it is more conducive to reducing noise.

[0010] Further preferably, the lateral protrusions correspondingly arranged on both sides of the tread pattern groove are cross-distributed.

[0011] Preferably, among the multi-layer lateral protrusions, the diameters and lengths of the lateral protrusions in each layer are the same.

[0012] Preferably, at least three layers of multi-layer lateral protrusions are provided.

[0013] Preferably, there are gaps between the layers of the multi-layer lateral protrusions, and there are gaps between adjacent lateral protrusions in each layer.

[0014] Preferably, scales are provided on both sides of the tread groove at the position of the wear mark, and numbers are provided on the scales.

[0015] A new energy vehicle tire provided by the present utility model has multi-layer lateral protrusions provided on the side walls of the tread grooves. According to the wear conditions of the protrusions, it is very intuitive to see the wear conditions of various positions of the tire, and it is possible to judge whether to prepare a new tire and replace the tire in time according to the wear conditions of the lateral protrusions; due to the arrangement of the multi-layer lateral protrusions from the outside to the inside and the cross-distribution of the lateral protrusions correspondingly arranged on both sides, during the running of the vehicle, when encountering sundries such as stones and gravels, due to the elastic force of the lateral protrusions, to a certain extent, it can prevent stones and gravels from getting stuck in the tread grooves, reducing the damage and wear to the tread pattern. Even if they get stuck in the tread grooves, it will cause relatively serious wear of the lateral protrusions near the position where the stones and gravels are stuck, allowing people to discover it in time and remove the stones and gravels; the setting of the multi-layer lateral protrusions is also conducive to reducing noise and does not affect drainage.

[0020] Next, the technical solutions of the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope claimed by the present application.

[0021] As Figure 1 shown, a new energy vehicle tire provided by the present utility model includes a tire body. A wear mark 3 is provided on the tire body. The wear mark 3 is provided at the bottom of the tread groove 1. Multiple layers of transverse protrusions 2 are provided on both sides of the tread groove 1. Each layer of transverse protrusions 2 is distributed along the circumferential direction of the tire with the center of the tire as the center. The outermost layer of transverse protrusions 2 (outer surface) is flush with the tread, and the innermost layer of transverse protrusions 2 (inner surface) is flush with the height of the wear mark 3.

[0022] In another implementation mode, the distance between the outermost layer of transverse protrusions 2 opposite to each other on both sides of the groove 1 is less than the distance between the innermost layer of transverse protrusions 2 opposite to each other. The sum of the lengths of the innermost layer of transverse protrusions 2 provided on both sides of the tread groove 1 is less than the length of the wear mark 3.

[0023] In another implementation mode, the distance between the transverse protrusions 2 opposite to each other on both sides of the groove 1 gradually decreases from the outermost layer to the innermost layer. As Figure 2 shown.

[0024] In another implementation mode, the distance between the transverse protrusions 2 opposite to each other on both sides of the groove 1 first decreases, then increases, and then decreases from the outermost layer to the innermost layer, and circulates in this way. As Figure 3 shown, it is more beneficial to reduce noise and prevent stones, gravel, etc. from getting stuck in the groove 1.

[0025] In another implementation mode, the transverse protrusions 2 corresponding to both sides of the tread groove 1 (in the same layer, circumferential direction) are cross-distributed.

[0026] In another implementation mode, among the multiple layers of transverse protrusions 2, the diameters and lengths of the transverse protrusions 2 in each layer are the same. There are gaps between the layers of the multiple layers of transverse protrusions 2, and there are gaps between adjacent transverse protrusions 2 in each layer.

[0027] In another implementation mode, the multiple layers of transverse protrusions 2 are provided with at least three layers.

[0028] In another embodiment, scales are provided on both sides of the tread groove 1 where the wear mark 3 is located, and numbers are provided on the scales. The numerical value represents the thickness of the tire tread pattern. The wear condition can be judged more accurately through the scales.

[0029] In another embodiment, the lateral protrusion 2 and the tire body are integrally formed, or other connection methods can also be adopted according to the existing technology.

[0030] A new type of new energy vehicle tire provided by the present utility model is provided with multiple layers of lateral protrusions 2 on the side wall of the tread groove 1. According to the wear condition of the protrusions, the wear condition of each position of the tire can be very intuitively seen. Whether to prepare a new tire and replace the tire in time can be judged according to the wear condition of the lateral protrusion 2, providing safety protection; due to the arrangement of the multiple layers of lateral protrusions 2 from the outside to the inside and the cross-distribution of the lateral protrusions 2 arranged correspondingly on both sides, when the vehicle is driving, when encountering sundries such as stones and gravels, due to the elastic force of the lateral protrusion 2, to a certain extent, it can prevent stones and gravels from being stuck in the tread groove 1, reducing the damage and wear of the tread pattern. Even if it is stuck in the tread groove 1, it will cause the lateral protrusion 2 near the position where the stones and gravels are stuck to be worn more severely, allowing people to discover and remove the stones and gravels in time; the arrangement of the multiple layers of lateral protrusions 2 can disrupt the noise airflow generated by the tread groove 3, block the noise transmission, facilitate noise reduction, and does not affect the drainage situation.

[0031] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
