Description

Airless tires {AIRLESS TIRE}

The present invention relates to an airless tire, and more particularly, to an airless tire in which no air is injected therein, and which can be replaced when the outer circumferential surface of the tie is worn.

Rubber and the like, and the tire forming the outer circumferential surface of the wheel of the automobile is generally combined with the wheel of the automobile while injecting air into the automobile.

However, this type of tire may cause puncture due to the loss of injected air or wear or damage of the tire. Recently, many airless tires have been developed to solve this problem.

Airless tires are a type of tire in which no air is injected inside. They are designed with a complicated structure using thermoplastic resin between the tread and the wheel, and are flexible in shape deformation and restoration by impact.

In this way, airless tires should be able to absorb external shocks without using compressed air. To this end, the airless tires have been developed in order to diversify the spoke shape and to provide excellent buffering effect.

As another prior art, Korean Patent No. 10-1043001 discloses "airless tires ". Specifically, air pressure is not used but a shock is absorbed through an Auxetic type spoke buffer, and a pressure To an airless tire, comprising: a cylindrical ground contacting portion contacting a ground; A rotary shaft fixing portion located inside the ground contacting portion while forming a circumference smaller than the ground contacting portion; Shaped spokes for buffering while connecting the ground contact and the rotary shaft fixing part, while restoring the original shape when the pressure or impact is removed, thereby forming a superior tire. .

However, since the airless tires are used in contact with the ground, the tires (especially the outer circumferential surface) must be worn. In such a case, replacement of the expensive airless tires may cause cost and material waste. Therefore, it is necessary to develop a form in which a substantial portion of airless tires can be reused even when the tire is worn.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

Fig. 1 is a perspective view showing an airless tire 1 according to an embodiment of the present invention, Fig. 2 is a front view showing the airless tire 1 shown in Fig. 1, Fig. 3 is a front view showing an airless tire 1 shown in Fig. Fig. 4 is a view showing an airless tire 1 according to another embodiment of the present invention, and Fig. 5 is a view showing another embodiment of the present invention FIG. 6 is an exploded perspective view showing an airless tire 1 according to another embodiment of the present invention, and FIG. 7 is an exploded perspective view showing an airless tire 1 according to another embodiment of the present invention. 1 is a view showing a part of the construction of an airless tire 1. Fig.

An airless tire (1) according to the present invention comprises a hub (10), an inner band (30), a spoke (20) and an outer band (40).

The hub 10 is the most central part of the airless tire 1 and has a cylindrical shape and a rotary shaft S is provided at the center of the hub 10.

The hub 10 can be directly coupled to the rotation axis S of the car wheel and can be coupled to the rim that is coupled onto the rotational axis S of the car wheel. (The inner circumferential surface of the hub 10 is in close contact with the outer circumferential surface of the rim. Which may be combined in a combined form)

The distance from the rotation axis S to the outer circumferential surface of the hub 10 is larger than the diameter of the outer band of the hub 10 from the outer circumferential surface of the hub 10 The distance from the outer circumferential surface of the hub 10 to the outer circumferential surface of the outer band 40 may be longer than the distance from the outer circumferential surface of the hub 10 to the outer circumferential surface of the hub 10 as shown in FIG. Is preferably longer than twice the distance from the center to the center.

The inner band 30 is formed in a circular ring shape around the hub 10 and is preferably formed in a cylindrical shape having a short length and the inner band 30 is concentric with the hub 10.

The inner band 30 may be made of synthetic resin, rubber, or the like, and may include a metallic steel. It is a matter of course that the inner band 30 is formed in an elastically deformable form.

The inner band 30 preferably has an inner diameter that is twice or more as large as the outer diameter of the hub 10 and the inner band 30 and the hub 10 are connected by the spokes 20, The spokes 20 and the inner band 30 are combined. The hub 10, the spokes 20 and the inner band 30 can be made integral with each other.

The spokes 20, which are elastically deformable, may comprise a first spoke 21 and a second spoke 22.

The first spoke 21 is formed along the normal direction of the hub 10 and the inner band 30 and connects the hub 10 and the inner band 30 at the shortest distance.

It is preferable that the first spokes 21 are provided in plural numbers and repeatedly formed at regular intervals along the circumferential direction of the hub 10.

The second spokes 22 connect the first spokes 21 adjacent to each other and are formed in a direction intersecting the first spokes 21.

In particular, the second spokes 22 are curved, unlike the first spokes 21 forming a straight line, and the central portion is convex toward the hub 10. Therefore, both end portions of each second spoke 22 are curved outwardly, and the central portion is located closest to the hub 10, and compared with the case where the first spokes 21 are connected in a straight line, The length becomes longer.

The first spokes 21 are subjected to the compressive force along the longitudinal direction as the airless tire 1 touches the ground surface, so that the bending stress acting on the first spokes 21 can be effectively excluded.

At this time, the end of the second spoke 22 is curved toward the hub 10 and curvature decreases (when the curvature of the second spoke 22 is R1 and the external force acts before the external force acts, When the curvature of the two spokes 22 is R2, R1 > R2), so that the external force applied to the first spokes 21 can be effectively mitigated and the load can be dispersed along the second spokes 22 do.

In addition, in the present invention, since the second spokes 22 are curved, it is possible to prevent an unnecessary tensile force from being applied to the second spokes 22, and the elastic restoring effect can be increased.

A plurality of second spokes 22 are formed between any one of the first spokes 21 and the adjacent first spokes 21 and repeatedly formed to be spaced apart from each other along the normal direction of the inner band 30. [ In the airless tire 1 according to the present invention, it is preferable that the overall arrangement of the spokes 20 is in the form of a spider web.

The outer band 40 is formed in a circular ring shape around the hub 10 and is preferably formed in a cylindrical shape having a short length and the outer band 40 is also concentric with the hub 10.

The outer band 40 may be made of synthetic resin, rubber, or the like, and may include a metallic material. The outer band 40 is preferably formed in a resiliently deformable form.

It is preferable that the inner diameter of the outer band 40 coincides with the inner diameter of the inner band 30 and the width of the outer band 40 (the length in the direction of the rotation axis S) coincides with the width of the inner band 30.

On the outer circumferential surface of the outer band 40, a plurality of tread patterns 42 are formed like a normal tire.

The outer band 40 of the airbelt tire 1 according to the present invention can be separated from the inner band 30 while tightly fitting to the outer circumferential surface of the inner band 30. For this purpose, And a fastening protrusion 41 is formed on the outer band 40.

When the outer band 40 is sufficiently worn by using the airless tire 1 according to the present invention, the outer band 40 is separated from the inner band 30 and the new outer band 40 is separated from the inner band 30, It is possible to reduce the cost of the airless tire 1 by minimizing the waste of the airless tire 1 and to eliminate the inconvenience of replacing the entirety of the airless tire 1.

The fastening protrusion 41 is inserted into the fastening groove 31 and protrudes from the inner circumferential surface of the outer band 40 toward the inner band 30. At least two fastening protrusions 41 are preferably formed, and at least two fastening grooves 31 are also formed.

The fastening protrusion 41 and / or the fastening groove 31 are made elastically deformable.

The fastening protrusion 41 may be integral with the outer band 40 or may be formed separately from the outer band 40 and coupled to the outer band 40. In the latter case, the outer band 40 is formed with a groove or through-hole through which the fastening protrusion 41 is inserted.

The fastening protrusion 41 of the airless tire 1 according to the present invention may include a shoulder portion 41c, a neck portion 41b, and a head portion 41a. The fastening protrusion 41 may further include an insertion space 41d and a fixing pin 44.

The shoulder portion 41c forms a relatively outer portion in the fastening protrusion 41 and is provided inside the outer band 40 or exposed at the outer circumferential surface of the outer band 40. [ The shoulder portion 41c prevents the fastening protrusion 41 from being separated from the outer band 40 in a state where the head portion 41a is inserted into the fastening groove 31. [

The neck portion 41b is a portion extending from the shoulder portion 41c toward the hub 10 and is preferably formed along the normal direction of the outer band 40. [ The neck portion 41b has a constant section along its longitudinal direction (the normal direction of the outer band 40).

The head portion 41a forms a relatively inner portion in the fastening protrusion 41 and extends from the neck portion 41b toward the hub 10 so as to be wider than the neck portion 41b.

That is, the neck portion 41b is narrower than the shoulder portion 41c and the head portion 41a.

The fastening groove 31 may be formed such that the head portion 41a is inserted into the groove 41a or a portion of the neck portion 41b and the head portion 41a may be inserted into the fastening groove 31. [ That is, the engaging groove 31 has a larger inner diameter than its inlet (inlet on the outer peripheral surface of the inner band 30).

This makes it possible to prevent the fastening protrusion 41 from easily separating from the fastening groove 31 when the head portion 41a of the fastening protrusion 41 is inserted and inserted into the fastening groove 31. [

The fastening protrusion 41 may be fixedly coupled to the outer band 40 or may be movably coupled to the outer band 40. [

When the fastening protrusion 41 is fixedly coupled to the outer band 40, the head portion 41a of the fastening protrusion 41 protrudes inward from the inner circumferential surface of the outer band 40. The fastening protrusion 41 A portion of the neck portion 41b and the head portion 41a of the inner band 30 are inserted into the engaging groove 31 so that the outer band 40 and the inner band 30 are coupled to each other.

At this time, if necessary, the fastening protrusion 41 may be inserted into the fastening groove 31 in a state in which the inner band of the outer band 40 is stretched so as to expand.

4, the fastening protrusion 41 is coupled through the outer band 40 and the outer band 40 is coupled to the outer band 40, As shown in FIG.

A step is formed on the outer hole of the outer band 40 in which the fastening protrusion 41 is fitted so that the shoulder portion 41c of the fastening protrusion 41 is caught. On the inner hole of the outer band 40, It is preferable that the hole is formed so as to be extended so as to insert the head portion 41a.

The inner circumferential surface of the outer band 40 can easily be brought into close contact with the outer circumferential surface of the inner band 30 while the fastening protrusion 41 is movably engaged with the outer band 40, The fastening protrusion 41 is inserted into the fastening groove 31 by moving the fastening protrusion 41 inward so that the outer band 40 and the inner band 30 can be engaged with each other, The coupling between the inner band 30 and the outer band 40 is very easy.

The insertion space 41d is a hollow portion formed at the center of the shoulder portion 41c, the neck portion 41b and the head portion 41a. The neck portion 41b is formed as an opening at the shoulder portion 41c side And is formed into a deep hole toward the head portion 41a. It is preferable that the insertion space 41d has a constant section along the normal direction of the outer band 40.

The fixing pin 44 is inserted into the insertion space 41d to closely fit the insertion space 41d and is formed in a long rod shape along the longitudinal direction of the insertion space 41d (the normal direction of the outer band 40) . It is preferable that the diameter of the fixing pin 44 is equal to the diameter of the insertion space 41d.

In the airless tire 1 according to the present invention, the fixing pin 44 may be made of the same material as the other parts of the fastening protrusion 41, but may be made of other materials. In the latter case, for example, stainless steel, aluminum And may be made of a metallic material such as an alloy.

7 (a), in a state before the fastening protrusion 41 is inserted into the fastening groove 31, the fastening pin 44 is pulled outward so that the inner portion of the insertion space 41d is hollow State can be maintained.

The head portion 41a of the fastening protrusion 41 can be easily elastically deformed in the direction of contracting so that the head portion 41a of the fastening protrusion 41 is easily inserted into the fastening groove 31 .

The head portion 41a is completely inserted into the engaging groove 31 and then the fixing pin 44 is advanced to the inside of the insertion space 41d to completely fill the insertion space 41d, And the engagement groove 31 are completed. (See Fig. 7 (b)).

In this state, the elastic deformation of the head portion 41a, particularly, the elastic deformation of the head portion 41a in a contracted state is not easily performed. Therefore, the fastening protrusion 41 can be easily separated from the fastening groove 31 So that the outer band 40 and the inner band 30 can be firmly coupled to each other.

Such a structure can advantageously work even when the outer band 40 is worn to replace the outer band 40 and the fastening protrusion 41 is fastened by pulling the fastening pin 44 out of the insertion space 41d. So that it can be easily separated from the groove 31.

In the airless tire 1 according to the present invention, the engaging groove 31 and the engaging projection 41 preferably have a constant section along the direction of the rotation axis S. Thus, stable and uniform bonding between the inner band 30 and the outer band 40 can be achieved along the width direction of the airless tire 1.

It is preferable that the engaging groove 31 and the engaging projection 41 are formed in a region narrower than the widths of the inner band 30 and the outer band 40. That is, the fastening groove 31 and the fastening protrusion 41 are not formed so as to cross the entire width of the inner band 30 and the outer band 40, And the fastening protrusion 41 is formed at the center portion of the inner peripheral surface of the outer band 40. [

The fastening protrusion 41 is inserted into the fastening groove 31 and the outer band 40 is engaged with the inner band 30 so that the outer band 40 is moved in the direction of the rotation axis S from the inner band 30 It is possible to effectively prevent the detachment.

In the airless tire 1 according to the present invention, the outer band 40 may be manufactured in the form of a circular ring and joined to the inner band 30, or may be formed in a one- 30).

In the case where the outer band 40 is formed in the shape of a one-letter-shaped band, the two ends are in close contact with each other to form a circular ring shape. At this time, both ends have a structure 43 interlocking with each other ) And a structure 45 joined by separate fastening means (see Figure 5).

In the former case, protrusions 43a are repeatedly formed at one side end of the strip, and other protrusions 43b are repeatedly formed at the other end, so that the protrusions 43a and 43b can be engaged with each other For example, a zipper.

In the latter case, one locking projection 45a is formed at one end of the one-side strip, another locking projection 45b is formed at the other end, and hooks 45c and 45c for fastening the two locking projections 45a and 45b ) Can be used to effect the coupling.

As described above, according to the airless tire 1 of the present invention, since the outer band 40 is detachable from the inner band 30, it is possible to easily replace the outer band 40 when the outer band 40 is worn, The connection between the outer band 40 and the inner band 30 is made strong and easy by the protrusion 41 and the rigidity of the spokes 20 including the first spoke 21 and the second spoke 22 The excellent airless tires 1 can be provided.
