Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. In practice, the invention will be understood to cover all modifications and variations of this invention provided they come within the scope of the appended claims.

For a better illustration of the invention, the following detailed description of the invention is given in conjunction with the accompanying drawings.

Examples

A tire tread, see figure 1, combine figure 2, including the pawl assembly and dust cover assembly, the said pawl assembly includes several pawls 1 that are set up in the tread, the said dust cover assembly includes several dust covers 2; at least one side of the pawl 1 is provided with the corresponding dustproof sleeve along the circumferential rolling direction of the tread.

The dust boot will be described below.

The dust cover 2 is of a structure with large elastic deformation capacity. Specifically, the dust-proof cover may be a solid or hollow structure, as long as it has a large elastic deformation capability, which means that when the dust-proof cover contacts the ground during vehicle driving, the dust-proof cover may be flattened and attached to the outer wall of the tire or to the outer side surface of the pawl, the material of the dust-proof cover is not particularly limited, and the dust-proof cover may be made of an existing material, such as an elastic rubber material. If the dustproof sleeve is of a hollow structure, the dustproof sleeve is of a thin-wall structure, so that deformation is easier to realize.

The pawl 1 and the corresponding dust-proof sleeve 2 arranged on at least one side of the pawl 1 are in corresponding relation to each other to form a dust-proof unit, and for the convenience of distinguishing the pawl and the dust-proof sleeve before different dust-proof units, one of the dust-proof units is described below.

The dustproof sleeve comprises a first dust blocking surface 202, the first dust blocking surface 202 is a surface on the outer side of the dustproof sleeve 2, the surface is far away from the corresponding pawl 1, and the first dust blocking surface 202 corresponds to the cambered surface which is bent towards the pawl 1. When the wheel rotates, this dirt proof boot 2 and road surface contact in-process, the dirt proof boot takes place deformation, flattens the laminating at tire outer wall or laminate at the pawl lateral surface, and the orientation corresponds the cambered surface of pawl 1 crooked, the streamlined design of first dust blocking surface 202 makes more easily dirt proof boot 2 toward the orientation deformation takes place for the direction of pawl 1, and self produces less raise dust to, its recovery after deformation blocks the raise dust that pawl 1 during operation produced, has dustproof effect that presses down dirt. The first dust blocking surfaces 202 on the left side and the right side of the pawl 1 can form a large arc surface with a broken middle due to the arc structure of the first dust blocking surfaces, and the large arc surface is in a streamline design, so that the dust prevention and suppression are enhanced; moreover, even if the dustproof sleeve is partially damaged, the overall streamline design can still better play the dustproof and dust suppression effects.

The dustproof sleeve 2 comprises a second dust blocking surface 201, and the second dust blocking surface 201 is a surface, close to the corresponding pawl 1, on the outer side of the dustproof sleeve 2. The second dust blocking surface 201 is arranged to be matched with the outer side surface 101 of the pawl 1 close to the second dust blocking surface, so that the gap between the second dust blocking surface 201 and the outer side surface 101 is more uniform, and the extrusion and shrinkage of the cavity structures on two sides are facilitated. If the outer side surface 101 of the pawl 1 is set to be an arc surface, the bending direction of the arc surface faces the bending of the pawl, the second dust blocking surface 201 faces the corresponding arc surface of the pawl 1, and the second dust blocking surface 201 and the outer side surface 101 are matched in such a way, so that the gap between the second dust blocking surface 201 and the outer side surface 101 is more uniform. When the wheels rotate, in the process that the dustproof sleeve 2 leaves the road surface, the dustproof sleeve 2 is not extruded any more, restores the original shape and blocks the sand and stone raised by the pawl 1, and faces to the corresponding curved cambered surface of the pawl 1, and the second dust blocking surface 201 is designed to be streamline so as to easily catch the sand and stone raised by the pawl 1 to the maximum extent.

The first and second are only for distinguishing the dust-blocking surface, and are not specific to the precedence relationship.

The pawl is further described below.

The pawls are uniformly distributed on the tire tread, so that the dustproof dust suppression effect and the large traction capacity effect are uniformly distributed.

The pawls are of a material having rigidity such that the pawls 1 deform less when the tread contacts the road, further ensuring a large traction capacity. Specifically, the material of the pawl can be selected from the existing materials with higher hardness, or the pawl is filled with the material to realize the rigidity of the pawl.

The outer side surface of the pawl 1 is provided with a cambered surface 101, and the bending direction of the cambered surface is bent towards the pawl. The arrangement of the cambered surface enables the end part of the pawl to be sharper, and the traction force to be larger. Of course, the cross-section of the pawl could be rectangular or other conventional shape, as long as increased traction is accomplished.

The pawl is of a toothed strip structure.

In an embodiment, with reference to fig. 1, said

dust boots

21, 22 are provided on both sides of each of said pawls 1 in the circumferential direction of the tread rolling. Referring to fig. 2, fig. 2 shows that the pawl 1 is filled with a material and has a certain rigidity; the dust covers 21 and 22 are thin-walled structures, are made of elastic rubber materials and have large elastic deformation capacity. When the tread contacts with the road surface, the deformation of the pawl 1 is small, the elastic deformation of the

dustproof sleeves

21 and 22 is large, the dustproof sleeves are flattened and attached to the outer wall of the tire, and the pawl 1 can fully contact with the road surface, so that the tire has large traction capacity. When the wheel rotates, the

dustproof sleeve

21 or 22 is not squeezed any more in the process that the tread leaves the road surface, and the original shape is restored and the raised sand and stones of the pawl 1 are blocked. In the whole process, the

dustproof sleeves

21 and 22 are in streamline design and deform to be attached to the tire wall, so that raised dust generated by the dustproof sleeves is small and the raised dust generated when the pawl 1 works is blocked, and the dustproof and dust suppression effects can be achieved.

A tire comprising the tire tread of any of the above. The tire may be an inflatable tire or a non-inflatable tire.
