Description
Technical Field
The present disclosure relates to a wheel for a non-pneumatic tire that prevents the non-pneumatic tire from sliding and separating from the surface of a rim.
Background
Common vehicle tires are classified into several types based on their structures. Most tires for passenger vehicles are radial tires. A radial tire is attached to a rim connected to an axle (axle) of a general vehicle, and the radial tire is filled with air under an appropriate air pressure and then used for driving. However, when the pneumatic tire does not have sufficient internal air pressure, it is difficult to support the vehicle load and to absorb the impact from the ground, resulting in deterioration of riding comfort. Therefore, the pneumatic tire needs to be regularly maintained.
However, even if the pneumatic tire is regularly maintained, there is a safety problem in that it is impossible to prevent damage caused by impact or puncture that may occur during driving. In order to solve the above-described problems, a non-pneumatic tire that does not require air pressure has been developed. The non-pneumatic tire has an advantage in that air in the tire does not need to be maintained, and thus a problem due to insufficient air pressure during running does not occur. The non-pneumatic tire is attached to the surface of the rim by a surface adhesive.
However, it is difficult to stably hold the combination of the non-pneumatic tire and the rim during high-speed running. Further, when a high rotational force is applied to the wheel, the non-pneumatic tire slides or separates from the rim due to centrifugal force, and does not remain fixed to the rim. Therefore, the non-pneumatic tire does not transmit the rotational force generated from the axle to the ground but may be displaced from the rim, which may cause an accident. On the other hand, when the adhesive is excessively applied between the non-pneumatic tire and the rim, it is difficult to remove the non-pneumatic tire from the rim due to the excessive adhesion, which results in difficulty in replacing the non-pneumatic tire.

Referring to fig. 1, a wheel 1 may include a rim 10 connected to an axle of a vehicle, and a non-pneumatic tire 20 fixed to the rim 10. The non-pneumatic tire 20 is attached to the rim 10 and supports the weight and dynamic load of the vehicle (if any). Further, the non-pneumatic tire 20 can transmit driving force and braking force to the road while running, and absorb or reduce the shock transmitted from the road. Hereinafter, a rim 10 and a wheel including the rim according to a first embodiment of the present disclosure will be described with reference to fig. 1 to 4.
Referring to fig. 1 to 4, the rim 10 may include: a rim wall portion 100 that is connected to an axle of a vehicle or the like and is provided on an inner peripheral side of the non-pneumatic tire; a rim flange portion 200 protruding radially from the rim wall portion 100; a fastening unit 300 for detachably fixing the rim flange portion 200; a fixing member 400 detachably fixed to the rim wall portion 100 and supporting the non-pneumatic tire 20; and a locking unit 500 for detachably fixing the fixing member 400 to the rim flange portion 200.
The rim wall portion 100 has a columnar shape and can be coupled with the inner peripheral surface of the non-pneumatic tire 20. A tire fixing portion 110 engageable with the inner peripheral surface of the non-pneumatic tire 20 may be formed at the outer peripheral surface of the rim wall portion. Further, the tire fixing portion 110 may extend from one end toward the other end in the axial direction "a". In the drawings according to the present embodiment, the tire fixing portion 110 is a fixing groove recessed inward in the radial direction "r". However, the tire fixing portion 110 is not limited thereto, and may be a fixing protrusion protruding outward in the radial direction "r". The rim wall portion 100 may have various shapes corresponding to the shape of the inner peripheral surface of the non-pneumatic tire 20.
The rim flange portion 200 protrudes from the rim wall portion 100 in the radial direction "r" and may be detachably coupled with the rim wall portion 100 at one side or both sides in the axial direction "a". The rim flange portion 200 may cover the rim wall portion 100 at both sides in the axial direction "a".
The rim flange portion 200 may have a circular shape when viewed in the axial direction "a", and the radius of the rim flange portion may be larger than the radius of the rim wall portion 100. The rim flange portion 200 may protrude from the rim wall portion 100 in the radial direction "r" by the thickness of the inner band 21 in the radial direction "r" when viewed in a cross section perpendicular to the circumferential direction "c", which will be described later.
A plurality of rim flange portions 200 may be provided. Of the plurality of rim flange portions 200, the first rim flange portion 210 may be connected to the rim wall portion 100 at one side in the axial direction "a", and the second rim flange portion 220 may be connected to the rim wall portion 100 at the other side in the axial direction "a". The non-pneumatic tire 20 may be disposed between the first flange portion 210 and the second flange portion 220 when viewed in a cross section perpendicular to the circumferential direction "c". In other words, the rim flange portion 200 may provide a space for accommodating the non-pneumatic tire 20 and the rim wall portion 100. When the non-pneumatic tire 20 is accommodated in this space, the inner surface of the rim flange portion 200 may be brought into contact with the outer surface of the non-pneumatic tire 20.
A plurality of fastening units 300 may be provided to detachably fix the rim flange portion 200 to the side surface of the rim wall portion 100. For example, the fastening unit 300 may include: a first fastening hole 310 formed at the rim flange portion 200; a second fastening hole 320 formed at the rim wall portion 100; and a fastening pin 330 inserted into the second fastening hole 320 through the first fastening hole 310.
The first fastening hole 310 may be formed at a side surface of the rim flange portion 200 to penetrate the rim flange portion 200 in the axial direction "a". The second fastening holes 320 may be formed at the side surface of the rim wall portion 100 in the axial direction "a" and provided at positions corresponding to the first fastening holes 310. Female threads may be formed at an inner surface of at least one of the first fastening hole 310 and the second fastening hole 320. The fastening pins 330 are inserted into the second fastening holes 320 through the first fastening holes 310, thereby fixing the rim flange portion 200 to the rim wall portion 100. Male threads may be formed at the outer surface of the fastening pin 330 to engage with female threads of the first and second fastening holes 310 and 320.
The fixing member 400 may be a plate extending in the axial direction "a". The length of the fixing member 400 in the axial direction "a" may be greater than the distance between the first rim flange portion 210 and the second rim flange portion 220. The securing member 400 may be spaced a predetermined distance from the rim wall portion 100 in the radial direction "r". The predetermined distance may be equal to the thickness of the inner tape 21 in the radial direction "r". The rim wall portion 100 may be detachably connected to the rim flange portion 200 such that the rim flange portion 200 is supported by the rim flange portion 200 at one end and the other end in the axial direction "a". When the fixing member 400 is fixed to the rim flange portion 200, the surface of the fixing member 400 facing the rim wall portion 100 may be in contact with the inner surface of the insertion hole 27 in the radial direction "r" and the circumferential surface of the rim flange portion 200, and the inner surface of the insertion hole 27 in the radial direction "r" may be the outer circumferential surface of the inner band 21. The inner surface of the fixing member 400 in the radial direction "r" may have substantially the same curvature as the inner surface of the rim flange portion 200. In this case, the fixing member 400 itself may be bent.
The plurality of fixing members 400 may be disposed at predetermined intervals in the circumferential direction "c".
The locking unit 500 may detachably fix the fixing member 400 to the outer circumferential surface of the rim flange portion 200. For example, the locking unit 500 may include: a first locking hole 510 formed at the fixing member 400; a second locking hole 520 formed at the outer peripheral surface of the rim flange portion 200; and a locking pin 530 inserted into the second locking hole 520 through the first locking hole 510.
A first locking hole 510 may be formed at the fixing member 400 to pass through in the radial direction "r". The second locking hole 520 may be formed at the outer circumferential surface of the rim flange portion 200 in the radial direction "r" and provided at a position corresponding to the first locking hole 510 of the fixing member 400. A female thread may be formed at an inner surface of at least one of the first locking hole 510 and the second locking hole 520. The locking pin 530 is inserted into the second locking hole 520 through the first locking hole 510, thereby fixing the fixing member 400 to the rim flange portion 200. Male threads may be formed at the locking pin 530 to engage female threads of the first locking hole 510 and the second locking hole 520.
The locking unit 500 may be disposed on one side and the other side in the axial direction "a" of the fixing member 400. A plurality of locking units 500 may be provided to correspond to the number of the fixing members 400. For example, if two locking units 500 are configured to fix one fixing member 400 at both sides in the axial direction "a" and ten fixing members 400 are provided, twenty locking units 500 may be provided. Further, the locking unit 500 may be disposed between the plurality of fastening units 300 in the circumferential direction "c".
The rim 10 constructed as described above can fix the non-pneumatic tire 20 on the outer peripheral side. Hereinafter, the non-pneumatic tire 20 will be described.
The non-pneumatic tire 20 may include: an inner band 21 that can be coupled to the rim 10 on an inner peripheral surface thereof; an outer belt 22 spaced apart from the inner belt 21 and covering an outer circumferential surface of the inner belt 21; spokes 23 disposed between the outer band 22 and the inner band 21; a shear band 24 surrounding the outer peripheral surface of the outer band 22; a tread 25 surrounding the outer peripheral surface of the shear band 24; and an insertion hole 27 into which the fixing member 400 of the rim 10 is inserted.
The inner band 21 may have a shape corresponding to the shape of the rim 10. A rim locking portion 21a engaged with the tire fixing portion 110 of the rim 100 may be formed on the inner peripheral surface of the inner band 21. The rim locking portion 21a may extend in the axial direction "a" from one end toward the other end. In the drawing according to the present embodiment, the tire fixing portion 110 is a fixing groove, and the rim locking portion 21a is a protrusion protruding inward in the radial direction "r". However, the rim locking portion 21a is not limited thereto, but may prevent the non-pneumatic tire 20 from slipping as long as it has a shape corresponding to the tire fixing portion 110. Therefore, when the tire securing portion 110 is a securing protrusion protruding outward in the radial direction "r", the rim locking portion 21a may be a groove recessed outward in the radial direction "r".
The outer belt 22 may surround the inner belt 21 while being spaced apart from the inner belt 21 by a predetermined distance. In other words, the radially inner peripheral surface of the outer band 22 and the radially outer peripheral surface of the inner band 21 may face each other. The outer band 22 and the inner band 21 may be connected by spokes 23.
The shear band 24 may primarily reduce the initial stress on the non-pneumatic tire 20. The shear band 24 may be formed in one or more layers made of a composite material comprising carbon fibers or steel cords. For example, the shear band 24 may be formed in one or more layers made of CFRP (carbon fiber reinforced plastic) or a wire rope band for a pneumatic tire.
The tread 25 may be provided on a radially outer circumferential surface of the shear band 24. The tread 25 is provided on the outermost side of the non-pneumatic tire 20 and may be in direct contact with the ground. For the tread 25, various treads commonly used in the art may be employed.
The insertion hole 27 may provide a space for inserting the fixing member 400 into the non-pneumatic tire 20 in the axial direction "a". By the fixing member 400 being brought into contact with at least the inner surface of the insertion hole 27 in the radial direction "r", and due to the deformation of the non-pneumatic tire 20 in the axial direction "a", the non-pneumatic tire 20 can be prevented from being separated or slid from the rim 10.
The insertion hole 27 may be defined by the spoke 23. In other words, the plurality of spokes 23 extending in the axial direction "a" may be arranged at predetermined intervals in the circumferential direction "c". The space between the spokes 23 may become the insertion hole 27. The fixing member 400 may fix the non-pneumatic tire 20 by contacting the inside of the insertion hole 27 in the radial direction "r".
According to the first embodiment, since the non-pneumatic tire 20 and the rim 10 are structurally fastened without using an adhesive or a fastening material, the non-pneumatic tire can be removed. In addition, the non-pneumatic tire 20 can be prevented from slipping or separating from the rim 10, and the rotational force of the rim 10 can be transmitted to the non-pneumatic tire without loss. In addition, the bearing capacity, load shock absorbing capacity and responsiveness to driving (including running, stopping and changing direction) of the tire can be improved.
In the first embodiment, the radially inner surface of the fixing member 400 is flat. However, according to the first modification and the second modification described below, a recess or a protrusion may be formed at the fixing member 400. Hereinafter, differences between the first embodiment and the first and second modifications will be described mainly with reference to fig. 5 and 6. In addition, the same reference numerals will be given to the same components, and redundant description thereof will be omitted.
As shown in fig. 5, according to a first modification of the first embodiment, a groove 410 may be formed on an inner surface of the fixing member 400 in a radial direction "r". The groove 410 may extend in the circumferential direction "c". In other words, the fixing member 400 may protrude inward in the radial direction "r" at both sides in contact with the rim flange portion 200. The length of the recess 410 in the axial direction "a" may be equal to or smaller than the distance between the first rim flange portion 210 and the second rim flange portion 220.
As shown in fig. 6, according to a second modification of the first embodiment, a protrusion 420 may be formed at an inner surface of the fixing member 400 in the radial direction "r". The protrusion 420 may extend along the circumferential direction "c". In other words, the fixing member 400 may be recessed outward in the radial direction "r" at both sides in contact with the rim flange portion 200. The length of the protrusion 420 in the axial direction "a" may be equal to or smaller than the distance between the first rim flange portion 210 and the second rim flange portion 220.
In the first embodiment, the insertion hole 27 is defined by the spoke 23. However, according to a second embodiment to be described later, the insertion hole 27 may be formed at the inner tape 21. Hereinafter, differences between the first embodiment and the second embodiment will be mainly described with reference to fig. 7 to 10. In addition, the same reference numerals will be given to the same parts, and redundant description thereof will be omitted.
As shown in fig. 7 to 10, according to the second embodiment, a hole 201 into which the fixing member 400 is inserted in the axial direction "a" may be formed at the rim flange portion 200 in the axial direction "a". The aperture 201 may be formed at the first rim flange portion 210 and the second rim flange portion 220. Further, the hole 201 may have a shape corresponding to that of the end of the fixing member 400 to accommodate the end of the fixing member 400. The insertion hole 27 may be formed at the inner tape 21 in a shape corresponding to that of the fixing member 400. In other words, the insertion hole 27, the hole 201, and the fixing member 400 may have the same shape when viewed in the axial direction "a". Accordingly, the outer surface of the fixing member 400 is brought into close contact with the inner surface of the hole 201. Therefore, the non-pneumatic tire 20 can be more stably fixed. At least one of the holes 201 formed at the first rim flange portion 210 and the second rim flange portion 220 may be a through hole.
In a state in which the fixing member 400 is inserted into the holes 201 and the insertion holes 27, the locking pins 530 are inserted into the first locking holes 510 of the fixing member 400 and the second locking holes 520 of the rim wall portion 100, thereby fixing the fixing member 400.
According to the present embodiment, after the non-pneumatic tire 20 is engaged with the rim 10, the fixing member 400 can be inserted into the insertion hole 27 formed at the non-pneumatic tire 20. The both end portions of the fixing member 400 inserted into the insertion hole 27 may protrude from the non-pneumatic tire 20 when viewed in the radial direction "r". The rim flange portion 200 may then be connected to the rim wall portion 100 to cover the rim wall portion 100 at both sides in the axial direction "a". At this time, the protruding end portion of the fixing member 400 may be received in the hole 201 formed at the rim flange portion 200. The inserted fixing member 400 may be fixed to the rim flange portion 200 by a locking pin 530.
In the present embodiment and the drawings thereof, the hole 201 is a recess, and the rim flange portion 200 is coupled to the rim wall portion 100 after the fixing member 400 is inserted into the insertion hole 27. However, the present disclosure is not limited thereto. In another example, the hole 201 may be a through hole extending in the axial direction "a", and the fixing member 400 may be inserted into the insertion hole 27 through the hole 201 after the rim flange portion 200 is coupled to the rim wall portion 100.
The inner tape 21 fixed by the fixing member 400 may not protrude or be recessed from the rim flange portion 200. In other words, the thickness of the inner band 21 in the radial direction "r" may be equal to the length of the rim flange portion 200 protruding from the rim wall portion 100 in the radial direction "r". However, the concept of the present invention is not necessarily limited thereto, and the inner band 21 may protrude from the rim flange portion 200 or may be recessed from the rim flange portion 200. In other words, in another example, the thickness of the inner band 21 in the radial direction "r" may be greater than the length of the rim flange portion 200 protruding in the radial direction "r" from the rim wall portion 100 (refer to fig. 9). In yet another example, the thickness of the inner band 21 in the radial direction "r" may be less than the length of the rim flange portion 200 protruding in the radial direction "r" from the rim wall portion 100 (refer to fig. 10).
According to the present embodiment, since the non-pneumatic tire 20 supports the fixing member 400 in the axial direction "a", the force applied in the radial direction "r" of the non-pneumatic tire 20 can be stably received. Therefore, it is possible to prevent the non-pneumatic tire 20 from slipping or separating from the rim 10 even during high-speed running, and also to prevent the fastening unit 300 and the locking unit 500 from being damaged by the force applied to the non-pneumatic tire 20 in the radial direction "r".
Although specific embodiments of a rim for a non-pneumatic tire and a wheel including the rim have been described in accordance with embodiments of the present disclosure, they are merely examples. The present disclosure is not limited thereto but should be construed broadly in accordance with the basic concepts disclosed in the present specification. Those skilled in the art can practice patterns of unspecified shapes within a certain scope by combining and substituting the disclosed embodiments without departing from the scope of the present disclosure. In addition, the disclosed embodiments may be readily changed and modified by those skilled in the art based on the present description, and it is apparent that such changes or modifications are within the scope of the present disclosure.
