Description

Rim of non-pneumatic tire and wheel comprising same
Technical Field
The present disclosure relates to a wheel for a non-pneumatic tire that prevents the non-pneumatic tire from slipping and separating from the surface of a rim.
Background
General vehicle tires are classified into several types based on their structures. Most tires for passenger vehicles are radial tires. A radial tire, which injects air at an appropriate air pressure and then is used for driving, is attached to a rim connected to a wheel axle (axle) of a general vehicle. 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 periodically maintained.
However, even if the pneumatic tire is regularly maintained, there is a safety problem in that it is impossible to prevent damage due to impact or puncture, which may occur during driving. To solve the above problems, non-pneumatic tires that do not require air pressure have been developed. The non-pneumatic tire has an advantage in that it is not necessary to maintain air in the tire, and thus problems due to insufficient air pressure during running do not occur. The non-pneumatic tire is attached to the surface of the rim by a surface adhesive.
However, it is difficult to stably maintain 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 slips 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 wheel shaft 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.
Disclosure of Invention
In view of the above, the present disclosure provides a rim capable of stably fixing a non-pneumatic tire, and a wheel including the rim.

The circumferential direction may be a clockwise direction or a counterclockwise direction when viewed from one side of the tire. Unless specifically mentioned, the above directions include positive and negative directions.
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 (if any) of the vehicle. Further, the non-pneumatic tire 20 can transmit driving force and braking force to a road while running, and absorb or reduce impact 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 connected to an axle of a vehicle or the like and provided on an inner peripheral side of the non-pneumatic tire; a rim flange portion 200 protruding in the radial direction 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 an inner peripheral surface of the non-pneumatic tire 20 may be formed at an 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 a 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. Among 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". When viewed in a cross section perpendicular to the circumferential direction "c", the non-pneumatic tire 20 may be disposed between the first flange portion 210 and the second flange portion 220. In other words, the rim flange portion 200 may provide a space for accommodating the non-pneumatic tire 20 as well as the rim wall portion 100. When the non-pneumatic tire 20 is accommodated in the 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 disposed at positions corresponding to the first fastening holes 310. A female screw may be formed at an inner surface of at least one of the first and second fastening holes 310 and 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 be engaged with the 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 fixing member 400 may be spaced apart from the rim wall 100 by a predetermined distance in the radial direction "r". The predetermined distance may be equal to the thickness of the inner band 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.
A 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 an outer circumferential 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.
The first locking hole 510 may be formed at the fixing member 400 to pass therethrough in a 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 disposed at a position corresponding to the first locking hole 510 of the fixing member 400. Female threads may be formed at an inner surface of at least one of the first and second locking holes 510 and 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 with the female threads of the first and second locking holes 510 and 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 it is configured that two locking units 500 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 couplable with the rim 10 on an inner peripheral surface thereof; an outer band 22 spaced apart from the inner band 21 and covering an outer circumferential surface of the inner band 21; spokes 23 disposed between the outer band 22 and the inner band 21; a shear band 24 surrounding the outer circumferential surface of the outer band 22; a tread 25 surrounding the outer circumferential 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 that engages with the tire fixing portion 110 of the rim 100 may be formed on an inner peripheral surface of the inner band 21. The rim locking portion 21a 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 recess, 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, and the non-pneumatic tire 20 can be prevented from sliding as long as it has a shape corresponding to the tire fixing portion 110. Therefore, when the tire fixing portion 110 is a fixing projection projecting outward in the radial direction "r", the rim locking portion 21a may be a recess recessed outward in the radial direction "r".
The outer band 22 may surround the inner band 21 while being spaced apart from the inner band 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.
Spokes 23 may be provided between the inner and outer bands 21, 22. The spokes 23 may serve as a support for connecting the inner and outer bands 21, 22. Further, the spokes 23 can serve as a cushioning material that distributes and absorbs impacts applied to the non-pneumatic tire 20, and can support the load of the vehicle to which the non-pneumatic tire 20 is coupled. A plurality of spokes 23 may be provided. When viewed in the axial direction "a", the spokes 23 may extend in the axial direction "a" and form a predetermined pattern (pattern) between the inner and outer bands 21, 22. However, the present invention is not limited thereto. In another example, the spokes 23 may extend in the circumferential direction "c" and form a predetermined pattern when viewed in the circumferential direction "c".
The shear band 24 may primarily reduce the initial stresses on the non-pneumatic tire 20. The shear band 24 may be formed in one or more layers made of a composite material containing 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 steel cord band for a pneumatic tire.
A tread 25 may be disposed on the radially outer peripheral surface of the shear band 24. The tread 25 is disposed 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 coming 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 separating or slipping from the rim 10.
The insertion holes 27 may be defined by the spokes 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 can fix the non-pneumatic tire 20 by contacting with the inner side 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. Further, the load bearing capacity, load impact absorbing capacity, and responsiveness to driving (including running, stopping, and changing directions) 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 and second modifications 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 members 400 may protrude inward in the radial direction "r" at both sides contacting the rim flange portion 200. The length of the groove 410 in the axial direction "a" may be equal to or less 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 contacting the rim flange portion 200. The length of the protrusion 420 in the axial direction "a" may be equal to or less than the distance between the first rim flange portion 210 and the second rim flange portion 220.
In the first embodiment, the insertion holes 27 are defined by the spokes 23. However, according to a second embodiment to be described later, the insertion hole 27 may be formed at the inner band 21. Hereinafter, the difference 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 hole 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 receive the end of the fixing member 400. The insertion hole 27 may be formed at the inner band 21 in a shape corresponding to the shape 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 comes 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 where the fixing member 400 is inserted into the hole 201 and the insertion hole 27, the locking pin 530 is inserted into the first locking hole 510 of the fixing member 400 and the second locking hole 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. Both end portions of the fixing member 400 inserted into the insertion holes 27 may protrude from the non-pneumatic tire 20 when viewed in the radial direction "r". Then, the rim flange portion 200 may be connected to the rim wall portion 100 so as to cover the rim wall portion 100 at both sides in the axial direction "a". At this time, the protruding end 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 groove, and after the fixing member 400 is inserted into the insertion hole 27, the rim flange portion 200 is coupled to the rim wall portion 100. 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 band 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 from the rim wall portion 100 in the radial direction "r" (refer to fig. 9). In yet another example, the thickness of the inner band 21 in the radial direction "r" may be smaller than the length of the rim flange portion 200 protruding from the rim wall portion 100 in the radial direction "r" (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", it is possible to stably receive the force applied in the radial direction "r" of the non-pneumatic tire 20. Therefore, the non-pneumatic tire 20 can be prevented from slipping or separating from the rim 10 even during high-speed running, and the fastening unit 300 and the locking unit 500 can also be prevented from being damaged by the force applied to the non-pneumatic tire 20 in the radial direction "r".
Although a specific embodiment of a rim for a non-pneumatic tire and a wheel including the rim according to an embodiment of the present disclosure have been described, they are merely examples.
