Description

Technical Field

[0001] The utility model relates to a bite-through tire structure, belonging to the field of tires. Background Art

[0002] With the development of society, traveling by car has become a common phenomenon, and the field of tires has made progress and development; during the driving of a vehicle, the traditional pneumatic tire has a standing wave phenomenon. The standing wave increases the friction between the tire and the ground, generating a large amount of heat. At the same time, this part of the standing wave pattern will cause the tread rubber to peel off from the inside of the tire carcass due to strong friction, resulting in a flat tire, and the flat tire cannot be processed in time after it occurs.

[0003] The non-pneumatic solid rubber tire reduces the standing wave phenomenon of the pneumatic tire and avoids flat tires, but the riding comfort decreases, and the shock absorption effect is not as good as that of the pneumatic tire.

[0004] The existing solid rubber tire structure is provided with through holes. During use, when the position directly below the through hole presses on the road surface, due to the lack of support in the through hole, the through hole will sink inward. There is rubber support at the position without through holes. When it presses on the road surface, it is a hard collision with the road surface. Therefore, this structure increases the bumpiness of the vehicle when driving on some road surfaces. Summary of the Utility Model

[0005] The utility model provides a bite-through tire structure, which reduces the problems of excessive depression and hard impact of the tire when the vehicle presses on the road surface and foreign objects, improves the driving stability of the vehicle; reduces the influence of the standing wave on the tire during driving and improves the handling comfort of tire use.

[0006] The technical solution adopted by the utility model is a bite-through tire structure, including a solid tire body, and the tire body has a carcass and a tread (); the carcass has a carcass structure;

[0007] The carcass structure includes transverse tire holes and longitudinal tire holes; the axial direction of the transverse tire holes is perpendicular to or forms an acute angle with the tire radial direction, and the longitudinal tire holes are arranged along the tire radial direction;

[0008] The transverse tire holes include a plurality of outer tire holes I and a plurality of inner tire holes II; all the outer tire holes I are on the outer side surface of the carcass, and all the outer tire holes I are arranged at equal intervals along the circumference of the outer side surface of the carcass; all the inner tire holes II are on the inner side surface of the carcass, and all the outer tire holes I are arranged at equal intervals along the circumference of the inner side surface of the carcass;

[0009] All the outer tire holes I and all the inner tire holes II are staggered in the circumferential direction of the carcass.

[0010] Optimally, for the above bite-through tire structure, the outer tire holes I and the inner tire holes II are both blind holes;

[0011] The depth of the outer tire hole 1 and the inner tire hole 2 is greater than half of the tire body thickness.

[0012] Optimally, in the above-mentioned bite-through tire structure, the longitudinal tire hole is a cavity formed by the overlapping part between the adjacent outer tire hole 1 and the inner tire hole 2.

[0013] Optimally, in the above-mentioned bite-through tire structure, the outer tire hole 1 overlaps with an adjacent inner tire hole 2 to form a longitudinal tire hole, or the outer tire hole 1 overlaps with two adjacent inner tire holes 2 to form a longitudinal tire hole.

[0014] Optimally, in the above-mentioned bite-through tire structure, the bottom of the outer tire hole one has a blind hole one, and the bottom of the inner tire hole two has a blind hole two;

[0020] The advantages of this application are:

[0021] In the technical solution of the present application, the stability of the tire is improved by the good comfort of the inner bite wear type tire and the characteristics that the standing wave is not easy to fluctuate. The use of reasonable bite design on both sides of the tire hole and the use of left and right side single-side inner bite embedding also reduces the use of raw materials.

[0030] The following further elaborates on the technical features of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0031] As shown in the figure, the present utility model is a bite-through type tire structure, including a solid tire body. The tire body has a carcass 2 and a tread 1). The carcass 2 has a carcass structure formed by hollowing out. When the tire travels on the road surface, the reaction force of the road surface can be transmitted to the carcass structure inside the carcass 2, and the reaction force of the road surface is offset by the deformation of the hollow hole structure of the carcass structure and the deformation of the carcass 2, improving the driving comfort. Using the elastic deformation and elastic recovery ability generated by the structure to replace the internal air filling of the pneumatic tire

[0032] In the present application, the carcass structure includes transverse tire holes and longitudinal tire holes; the axial direction of the transverse tire holes is perpendicular to or forms an acute angle with the tire radial direction, and the longitudinal tire holes are arranged along the tire radial direction.

[0033] The transverse tire holes include a plurality of first outer tire holes 21 and a plurality of second inner tire holes 22. All the first outer tire holes 21 are on the outer side surface of the carcass 2, and all the first outer tire holes 21 are arranged at equal intervals in a ring along the outer side surface of the carcass 2. All the second inner tire holes 22 are on the inner side surface of the carcass 2, and all the first outer tire holes 21 are arranged at equal intervals in a ring along the inner side surface of the carcass 2. All the first outer tire holes 21 and all the second inner tire holes 22 are staggered in the circumferential direction of the carcass 2.

[0034] Generally, the radial holes and axial holes of solid tires in the prior art cannot be formed by one-time processing. Moreover, the radial holes of solid tires can only be processed by opening holes on the tread or inner ring surface of the solid tire, and cannot be directly formed inside the tire carcass. Such a radial hole structure is slightly insufficient in terms of preventing the rear end of the vehicle from swaying, canceling the axial force and radial force of the tire, etc., and the processing is relatively cumbersome.

[0035] The longitudinal holes of the present application are formed by the overlapping of the bottom parts of the outer tire hole 21 and the inner tire hole 22, without the need to open holes on the tread or inner ring surface of the solid tire, and are completely inside the carcass 2. As shown in the figure, Figure 3 、 Figure 4 and Figure 5 In, the dotted line area formed by the overlapping part of the outer tire hole 21 and the inner tire hole 22 is the longitudinal tire hole area in the present application. In the technical solution of the present application, especially in the embodiment shown in Figure 4 As shown, through the hollow structure of the present application, the tire support ribs are arranged in a finished product shape or a shape similar to a finished product shape, forming a stable support body support rib, and can effectively solve the problem of ventilation and heat dissipation.

[0036] Specifically, both the outer tire hole 21 and the inner tire hole 22 are blind holes, and the hole depths of the outer tire hole 21 and the inner tire hole 22 are greater than half of the thickness of the carcass 2. When the hole depths of the outer tire hole 21 and the inner tire hole 22 are greater than half of the thickness of the carcass 2, the outer tire hole 21 extends from the outside to the inside of the carcass 2, and the inner tire hole 22 extends from the inside of the carcass 2 to the outside. Only in this case, it is possible for the outer tire hole 21 and the inner tire hole 22 to form an overlapping part and form a longitudinal tire hole. Such a longitudinal tire hole can be completely located inside the carcass 2. In this way, by the form of the outer tire hole 21 and the inner tire hole 22 overlapping and forming a longitudinal tire hole, that is, the "left and right structures are the same, bite and penetrate each other and stagger, and bite and penetrate and embed each other" of the present application, a tire with an "interlocking penetration type" structure inside is formed.

[0037] During actual operation, the outer tire hole 21 can overlap with an adjacent inner tire hole 22 to form a longitudinal tire hole, or the outer tire hole 21 can overlap with two adjacent inner tire holes 22 to form a longitudinal tire hole. The specific form selection can be made according to actual needs.

[0038] Alternatively, if the required size of the longitudinal tire hole is small and the design requirement of the transverse tire hole is large, the longitudinal tire hole can also be formed in the following manner. For example, the bottom of the outer tire hole 21 has a blind hole 211, and the bottom of the inner tire hole 22 has a blind hole 221. The longitudinal tire hole is a cavity formed by the overlapping part between the adjacent blind holes 211 and 221. In this way, the forming size of the longitudinal tire hole can be not limited by the forming sizes of the outer tire hole 21 and the inner tire hole 22.

[0039] The number of the outer tire holes 21 is set in cooperation with the number of the inner tire holes 22, and one inner tire hole 22 is arranged between two adjacent outer tire holes 21. In this embodiment, the number of the outer tire holes 21 can be the same as or different from the number of the inner tire holes 22, and the numbers of the outer tire holes 21 and the inner tire holes 22 are both odd numbers or both even numbers.

[0040] The shape of the outer tire hole 21 is set in cooperation with the shape of the inner tire hole 22, and the two shapes can be the same or different. The radial cross-sections of the outer tire hole 21 and the inner tire hole 22 can be selected from one of the shapes such as circular, oval, square, spindle-shaped, circular cut-corner rectangle, etc.

[0041] In the technical solution of the present application, for the convenience of description, the tire body 2 is divided into the inner side and the outer side. However, in the actual use process, the technical solution of the present application can also be applied to the tire structure with the same inner and outer structures.

[0042] The bite-through tire structure of the present application is based on a solid tire, that is, a solid tire. Since it is entirely composed of rubber, the tire structure of the present application is similar to that fixed together by more wheel spokes, and it has a high hardness. When the wheel axle rotates, compared with a pneumatic tire, the force is transmitted to the edge position of the tire all the time. At the same time, the whole solid tire is relatively hard, and it is difficult to generate standing waves, and the standing wave phenomenon is slight.

[0043] The outer tire hole 21 and the inner tire hole 22 are arranged on the inner bite-through tire structure. On the axial plane of the tire, that is, when observing with the line of sight parallel to the wheel axle, the line of sight cannot pass through the tire from one side to the other side, and the whole tire is an integral body, which can be understood as being fixed together by more spokes, and the force of the wheel axle is transmitted to the edge of the tire. However, compared with a solid tire without hollow holes, there are tire holes on it, so the comfort is good and the rigidity effect of the tire is slightly weaker than that of the solid tire.

[0044] When an inflated tire travels on a flat road surface and passes over a hard speed bump, the shock absorption effect is very good. The non-inflated tire has evenly distributed through holes on the solid tire. It can be understood that the annular rubber part between the tire crown and the inner ring surface of the tire is composed of several closely connected spokes. Some of the spokes are removed at intervals in this part, and only about half of the overall spokes are retained. Its rigidity effect is slightly stronger than that of the inner-engaging and penetrating tire of the present application; in terms of shock absorption effect and vehicle tire comfort, it is slightly weaker.

[0045] The solid tire is entirely composed of rubber and has no shock absorption structure. It performs well when traveling on a flat road surface. However, when passing over a hard speed bump, since the hard speed bump is a convex structure, similar to the collision of two rigid bodies, the solid tire will receive an upward reaction force at the contact position with the hard speed bump, and the solid tire will bounce upward. At this time, the shock absorption effect is poor.

[0046] For the inner-engaging and penetrating tire of the present application, staggered tire holes are provided on the original solid tire. When the tire is sectioned, it will be found that there are supports everywhere on the entire tire, and shock-absorbing tire holes are provided everywhere.

[0047] When traveling on a flat road surface, the left and right tire walls are in dynamic balance under the rotation of the tire, constantly supporting the tire and acting together on the tire crown 1, making the force on the tire more balanced, and the dynamic balance of the tire better, which is beneficial to the smoothness of tire travel.

[0048] When encountering a hard speed bump, each tire hole lacks rubber filling to achieve a shock absorption effect, while the positive tire wall on the back of the tire hole can receive the reaction force provided by the hard speed bump and generate support, preventing the tire from deforming too much. Its shock absorption effect is stronger than that of the non-inflated tire.

[0049] The existing non-inflated tire has through holes that penetrate both the inside and outside of the tire body on the solid tire. When traveling on a flat road surface, since there is no support at the through hole, when the area directly below the through hole touches the ground, the structural tire is slightly deformed, and the tire dents upward directly below the through hole. When rotating to the rubber wall between the two through holes, the rubber wall generates support and slightly bounces the tire. The understanding model is that a rubber gear with a very large number of teeth travels on the road surface. When passing over a hard speed bump, there is no support at the through hole. When pressing on the hard speed bump, the reaction force received by the tire contact position cannot be directly stressed, and the tire dent increases to offset the reaction force, and the tire deformation increases. However, when the support column between the two through holes presses on the hard speed bump, the reaction force acting on the tire contact position cannot be buffered, and the tire will bounce again. Therefore, when traveling on a flat road surface and passing over a hard speed bump, the shock absorption effect of the non-inflated tire is poor.

[0050] This embodiment is better than non-pneumatic tires and pneumatic tires in terms of the standing wave problem, and better than non-pneumatic tires and solid tires in terms of shock absorption effect. In general, it is the best structure among the four types of tires, with not only a small standing wave problem but also good shock absorption effect, increasing the comfort and stability of the tire carcass.

[0051] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention shall fall within the protection scope of the present invention.
