Description

[0001] The present invention relates to a wheel for a solid tire,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel for a solid tire of an automobile, and more particularly to a wheel for mounting and separating a solid tire.

A wheel is provided with a tire and is fastened to an axle to support a load of the vehicle and to transmit a driving force, a braking force and a lateral force to the road surface

The wheel comprises a cylindrical rim, a rim flange protruding outward at both ends of the rim to fix the tire, and a disk for fastening the wheel to the axle.

A tire connected to the wheel constructed as described above is a rubber tube filled with air and formed in a ring shape. It buffers various shocks transmitted from the outside world and transmits the driving force, braking force, and lateral force directly to the ground do.

Conventional tires are configured to be filled with air inside, which often results in a puncture caused by sharp objects such as nails, thereby losing tire functionality.

Particularly, if a puncture occurs during driving, a sudden collision of the vehicle due to the loss of the steering ability may cause a collision accident or cause a serious accident.

In order to solve such problems, a tire in which silica as a liquid adhesive is injected into a tire has been developed. However, a puncture caused by a nail or a fragment having a diameter of about 7 mm or less can be prevented, but a large nail There is a problem in that it has no effect on punctures generated on the side of the tire and does not correspond to punctures generated on the side of the tire at all.

Due to such a problem, a solid tire in which a tire is formed of a synthetic resin, a material such as silicone, and the like has been developed without charging air inside.

These solid tires are used in some combat vehicles because they do not charge air inside, which means they do not lose their tire function even when nails or pointed objects get caught in the tires or even shoot.

However, such a solid tire has a problem in that the material of the synthetic resin or the like constituting the tire is lost due to heat generated when the vehicle travels at high speed for a long time because the internal heat is large, and the tire function is lost. Further, in the cold winter, the solid tire material is hardened and the elasticity is lost, so that it can not absorb the external impact, and even the tire is broken.

In order to solve these problems, the present applicant has developed Korean Patent No. 10-1303078, "No puncture bulletproof tire ", and developed a non-puncture tire capable of traveling at a high speed of 100 km / h or more in a high- Bulletproof tire was developed.

Conventional solid tires are molded from a silicone rubber and a spherical EVA foaming agent in the form of a tire in advance, and it is very difficult or impossible to fasten to a conventional wheel.

In addition, since a tire to be filled with air is filled with high-pressure air inside the tire after being fastened to the wheel, a slip phenomenon does not occur between the wheel and the tire because the tire and the wheel are firmly connected. However, The driving force and the braking force are deteriorated due to the slip phenomenon between the wheel and the tire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings, wherein like reference numerals refer to like elements.

It is to be understood that when an element is referred to as being "comprising" another element in the description of the invention or in the claims, it is not to be construed as being limited to only that element, And the like.

1 and 3, the wheel 100 for a solid tire according to the present invention includes an outer wheel 110 and an inner wheel 120, which are divided in a direction orthogonal to the axial direction of the wheel 100.

3, the outer wheel 110 is formed with a cylindrical rim 111, a rim flange 112 is formed on one side of the rim 111 by protruding a predetermined length in the outer direction, A disk 113 having a hub fastening hole 114 for fastening the wheel 100 to the axle hub of the vehicle is formed in the inner wall 110 of the vehicle.

A rim fastener 115 for fastening with the inner wheel 120 is formed in the rim 111.

The inner wheel 120 is formed with a cylindrical rim 121 and a rim flange 122 protruding outward by a predetermined length on one side of the rim 121, A nut 123 having a fastener 124 is formed.

The outer wheel 110 and the inner wheel 120 are coupled to each other so that when the outer wheel 110 and the inner wheel 120 are fastened, the rim 111 of the outer wheel 110 and the rim fastener The inner wheel 120 and the rim fastener 124 are formed so as to be continuous with the rim 121 of the inner wheel 120 and the rim fastener 124, respectively.

A process of fastening the solid tire 130 to the wheel 100 of the present invention will be described.

First, the wheel 100 in which the outer wheel 110 and the inner wheel 120 are engaged is separated as shown in FIG.

Since the solid tire 130 is formed in a finished tire shape from the time of manufacture, it can not be inserted or hung by the rim flange of the wheel 100. Therefore, the wheel 100 is separated from the outer wheel 110 And the inner wheel 120 to remove the rim flange on either side of the wheel 100. [

After the outer wheel 110 and the inner wheel 120 are separated as described above, the solid tire 130 is inserted into the outer surface of the rim 121 of the inner wheel 120 as shown in FIG.

The spherical EVA foam is filled with 25 to 35 parts by weight of a spherical EVA foam with respect to 100 parts by weight of the silicone rubber. The spherical EVA foam is filled with silicone rubber and spherical EVA foam, And is shaped to have a diameter of 6 mm.

Silicone is a synthetic polymer organic compound that does not change its elasticity and physical properties even at 250 ° C and does not freeze even at -75 ° C but retains its elasticity and physical properties. It is a non-toxic substance and has excellent resistance to compression, chemical resistance, low temperature stretchability, It is excellent in flame retardancy, oil resistance, water resistance, and is environmentally friendly.

25 to 35 parts by weight of the EVA foam is mixed with the silicone rubber. Compared with 100% of the silicone rubber, the automobile fuel consumption is improved, the elasticity is improved, the riding comfort is improved, the shock absorbing property is improved, and the cost is reduced.

When the spherical EVA foam is mixed at less than 25 parts by weight, the elasticity of the tire is lowered, the shock absorbing property is lowered, and the riding feel at the time of high-speed driving is lowered. In addition, since the EVA price is 10 times lower and the weight is 5 times lighter than the silicone rubber, it is preferable to fill the EVA foam with 25 parts by weight or more. Further, when the EVA foam is more than 35 parts by weight, it is preferable that the EVA foam is filled so as not to exceed 35 parts by weight since the puncture and the bulletproof function are hindered.

The spherical EVA foam is preferably formed to have a diameter of 3 to 6 mm. When the diameter of the EVA filler is less than 3 mm, the spherical EVA foam is not mixed uniformly with the silicone rubber. Therefore, the EVA foam is molded to have a diameter of 3 mm or more, When punctured or stuck on a nail, steel bar, or iron plate, puncture or bulletproof function is weakened.

The solid tire 130 having the above-described structure is excellent in elasticity, tensile strength, heat resistance, and cold resistance, and therefore has a large diameter of 10 mm or more in diameter. However, even if a material such as reinforcing steel or steel plate is stuck on the bottom surface or side surface of a tire, , Water roads, etc. at a high speed of 100 km / h or more.

Of course, if the tire continues to travel at a high speed with a large nail, steel bar, and steel plate embedded in it, vibration and noise may occur because the wheel balance does not match. However, if the tire is stuck away,

The rim portion of the wheel 100 is divided into the outer wheel 110 and the inner rim 120 as described above so that the rim width of any one of the rims of the outer wheel 110 or the inner wheel 120 It is preferable that the solid tire 130 be more firmly fixed when the solid tire 130 is inserted into the rim and that the fastening operation be smoothly performed when the divided wheels are subsequently fastened Do.

The width of the rim 121 of the inner wheel 120 is made larger than the width of the rim 111 of the outer wheel 110 and the solid tire 130 The width of the rim 111 of the outer wheel 110 is formed to be greater than the width of the rim 121 of the inner wheel 120 and the solid tire 130 is fixed to the outer side Or may be configured to be inserted into the rim 111 of the wheel 110.

4, the solid tire 130 is inserted into the rim 121 of the inner wheel 120, and then the outer wheel 110 is fastened to the inner wheel 120 as shown in FIG.

6, when the fastening bolt is inserted into the rim fastening hole 115 of the outer wheel 110, the fastening bolt is engaged with the rim fastening hole 115 of the outer wheel 110 and the rim fastening hole 115 of the inner wheel 120, The outer wheel 110 and the inner wheel 120 are bolted to each other.

At this time, the rim 111 of the outer wheel 110 and the rim 121 of the inner wheel 120 come into contact with each other, and the outer surfaces of the rims 111 and 121 are smoothly and continuously connected.

The solid tire 130 can be easily and quickly fastened to the wheel 100 and the solid tire 130 can be quickly removed.

Conventionally, a tire is inserted into a wheel in a state where air is not charged, and then a high-pressure compressed air is filled in the tire to inflate the tire, so that the tire is tightly adhered to the rim and the rim flange so that the driving force and the braking force are transmitted to the tire On the contrary, since the solid tire 130 is inserted into the wheel 100 in an interference fit manner, a slipping phenomenon occurs between the wheel 100 and the solitary tire 130, so that the driving force and the braking force can be lost.

In order to prevent such a slip phenomenon between the solid tire 130 and the wheel 100, it is preferable to form a non-slip portion in the rim portion of the wheel 100. [

7, the non-slipping part 140 may be formed by radially forming a protrusion protruding outward from the rim 121 of the inner wheel 120, and a solid tire 130 corresponding to the non-slipping part 140, The solid wheel 130 is inserted into the groove of the solid tire 130 (not shown) when the solid wheel 130 is inserted into the inner wheel 120 by forming a groove (not shown) Thereby preventing the slip phenomenon between the wheel 100 and the solid tire 130 so that the driving force and the braking force are not lost.

Although the non-slip part is illustrated as protruding from the rim 121 of the inner wheel 120 in the embodiment of the present invention, the non-slip part may protrude from the rim 111 of the outer wheel 110.

A nut 123 formed on the inner surface of the rim 121 of the inner wheel 120 may protrude from the outer surface of the rim 121 to couple the outer wheel 110 and the inner wheel 120, (Not shown) may be formed in the solid tire 130 so as to correspond to the non-slip portion 123 of the tire.

The solid tire wheel constructed as described above can be separated by dividing the rim portion, so that the solid tire formed in advance into the tire shape from the time of manufacturing can be easily removed and attached.

Further, since the slip phenomenon does not occur between the solid tire and the wheel by constituting the non-slip portion in the rim portion, an accurate driving force and braking force can be secured.

The technical idea of the present invention has been described above with reference to the embodiments.

It will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described above from the description of the present invention.

Further, although not explicitly shown or described, those skilled in the art can make various modifications including the technical idea of the present invention from the description of the present invention Which is still within the scope of the present invention.
