Technical Field

The embodiment of the utility model provides a relate to tire technical field, especially relate to a non-pneumatic tire.

Background

Tires are generally classified into pneumatic tires and non-pneumatic tires. At present, a tire commonly used in the market is a pneumatic tire, the pneumatic tire uses rubber to seal pressure air, a skeleton support is provided by a steel wire or a cord thread bonded by the rubber, an annular rubber tire with a cavity inside is formed by complicated processes such as molding and vulcanization, and the tire forms a sealed space by assembling with a rim to seal compressed air. The pneumatic tire has high elasticity, so that the automobile has good buffering performance through the tire, but when the automobile is actually used, the problem of tire burst of the pneumatic tire causes air leakage in the tire, the pneumatic tire loses elasticity, so that the automobile cannot run stably, and the running performance of the tire is influenced to a certain extent due to the change of the internal temperature and the air pressure of the pneumatic tire. The problem that the automobile cannot run after being punctured is solved by the aid of the non-pneumatic tire, the non-pneumatic tire is provided with an elastic structure, the elasticity of the tire can be effectively maintained without inflation, most of existing non-pneumatic tires are complex in structure and not beneficial to production and manufacturing, and the non-pneumatic tire with a simple structure and good buffering performance is needed.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem that will solve provides a non-pneumatic tire, and shock-absorbing capacity is good and simple structure.

In order to solve the technical problem, the embodiment of the utility model provides an adopt a non-pneumatic tire, including the inner tube ring, be used for with the cover tire ring of ground contact and set up in the inner tube ring with spoke group between the outer tube ring, spoke group follows the tire is vertical to be divided into first spoke group and second spoke group in the mid-parting line, first spoke group with second spoke group all includes the spoke pair that a plurality of arranged along tire circumferencial direction, the spoke is to constituteing by the spoke of two adjacent arrangements, the spoke middle part takes place the inflection towards tire circumferencial direction, the spoke inflection direction of first spoke group with the spoke inflection opposite direction of second spoke group.

Further, the first spoke group and the second spoke group are spaced by a preset distance.

Furthermore, adjacent spokes of the spoke pair are parallel to each other, a first interval is formed between the adjacent spokes of the spoke pair, a second interval is formed between the spokes of the spoke pair and close to one side of the inner tire ring, and the first interval is larger than the second interval.

Further, a third spacing is provided between the pair of spokes adjacent to the outboard tire ring, and the third spacing is greater than the first spacing of the spacing between the adjacent spokes of the pair of spokes.

After the technical scheme is adopted, the embodiment of the utility model provides an at least, following beneficial effect has: the embodiment of the utility model provides a through set up including two spoke groups that a plurality of spoke is right between inner tube ring and cover tire ring, through set up the deflection at the spoke middle part, can effectively guarantee the buffer property of tire each position when rolling, set up the spoke deflection opposite direction of every spoke group simultaneously, form the cross structure at tire circumference face, can further promote the buffer property of tire, simple structure simultaneously, convenient production and processing.

Detailed Description

The present application will now be described in further detail with reference to the accompanying drawings and specific examples. It is to be understood that the following illustrative embodiments and description are only intended to illustrate the present invention, and are not intended to limit the present invention, and features in the embodiments and examples may be combined with each other in the present application without conflict.

An optional embodiment of the present invention provides a non-pneumatic tire, as shown in fig. 1-6, including inner tire ring 1, outer tire ring 3 for contacting with the ground and set up in inner tire ring 1 with spoke group 5 between outer tire ring 3, spoke group 5 follows the tire is vertically bisected and is divided into first spoke group 50 and second spoke group 52, first spoke group 50 with second spoke group 52 all includes a plurality of spoke pair 54 arranged along the tire circumferential direction, spoke pair 54 comprises 541 of two adjacent arrangements of spokes, 541 spokes middle part takes place the offset towards the tire circumferential direction, spoke offset direction a1 of first spoke group 50 is opposite to spoke offset direction a2 of second spoke group 52.

The embodiment of the utility model provides a through set up including two spoke groups of a plurality of spoke pair 54 between inner tube ring 1 and outer tube ring 3, through set up the deflection in spoke 541 middle part, can effectively guarantee the buffer performance of tire each position when rolling, set up the spoke deflection opposite direction of every spoke group simultaneously, form the cross structure at tire circumference face, can further promote the buffer performance of tire, simple structure simultaneously, convenient production and processing.

In yet another alternative embodiment of the present invention, as shown in fig. 1-5, the first spoke set 50 is spaced apart from the second spoke set 52 by a predetermined distance D.

In the embodiment, the first spoke set 50 and the second spoke set 52 are arranged at the preset distance D, so that the deformation of the first spoke set 50 and the deformation of the second spoke set 52 do not interfere with each other when the tire contacts the ground, and meanwhile, when the tire is subjected to the force in the Fy direction, the buffering can be effectively carried out, and the use performance of the tire is improved.

In yet another alternative embodiment of the present invention, as shown in fig. 6, the adjacent spokes 541 of the spoke pair 54 are parallel to each other, the adjacent spokes 541 of the spoke pair 54 are spaced apart by a first distance D1, the one side of the spoke pair 54 close to the inner tire ring 1 is spaced apart by a second distance D2, and the first distance D1 is greater than the second distance D2.

This embodiment sets up first interval D1 and sets up second interval D2 near one side of inner tube ring 1 between spoke pair 54 through set up first interval D1 between the adjacent spoke 541 of spoke pair 54, effectively separate each spoke 541, prevent that each spoke 541 from taking place deformation and mutual interference when because of the tire atress, set up first interval D1 simultaneously and be greater than second interval D2, when the tire atress, the deformation degree of adjacent spoke 541 is the same, the position deformation degree of spoke 541 near inner tube ring 1 one side is less, it sets up the interval that the interval is less than adjacent spoke 541, rationally arrange the spoke 541 of tire and set up the position, make the tire keep good shock-absorbing capacity.
