[Problems to be solved by the invention]

As described above, by using fiber-reinforced resin to form the rim, the rim is made lighter while ensuring strength. However, in recent years, it has been desired to further reduce the weight of the rim while ensuring the strength of the rim.

An object of the present invention is to provide a rim which is provided with a rim containing fiber-reinforced resin, and has a structure that can reduce the weight while ensuring strength. [Technical means to solve the problem]

First, in order to ensure the strength and further reduce the weight of the rim, the inventors studied to reduce the wall thickness of the rim. As a result, the inventors discovered the following.

A rim containing fiber-reinforced resin (hereinafter referred to as a fiber-reinforced resin rim) has a support portion, which is viewed from a cross section (hereinafter referred to as a radial cross section) when the rim is cut in the radial direction, respectively The width direction of the rim (the left-right direction of the vehicle) protrudes. Therefore, when a force is applied to the rim in the radial direction, the fiber-reinforced resin rim acts as if the both ends of the rim in the width direction (the left-right direction of the vehicle), that is, the front end of the support portion The displacement force in the radial direction of the rim.

Therefore, the inventors have noticed that if the strength of the fiber-reinforced resin rim is to be secured when the above-mentioned force is applied to the rim, it is difficult to reduce the wall thickness of the rim.

Specifically, the inventors found that the strength of the fiber-reinforced resin rim is lower than that of the portion where the valve hole is not provided in the periphery of the valve hole provided in the fiber-reinforced resin rim for mounting the valve. That is, the inventors have noticed that the fibers in the fiber-reinforced resin included in the fiber-reinforced resin rim are cut at the periphery of the valve hole, so the fiber is reinforced compared to the uncut parts The strength of the resin rim decreases around the periphery of the valve hole.

In the case of installing a valve on a fiber-reinforced resin rim, as the valve hole, a hole (for example, a diameter of 8.5 mm or 11.5 mm) that can be installed in the fiber-reinforced resin rim must be provided. When a valve hole of such a size is provided in a fiber-reinforced resin rim, as described above, the strength of the fiber-reinforced resin rim is reduced compared to a portion without holes. In addition, when mounting the valve on the fiber-reinforced resin rim, in order to install the valve on the fiber-reinforced resin rim, it is necessary to form a bearing surface around the valve hole. As a result, the thickness of the fiber-reinforced resin rim becomes smaller at the portion where the bearing surface is formed on the fiber-reinforced resin rim. In this case, the strength of the fiber-reinforced resin rim is lower than the portion where the bearing surface is not formed.

In response to this, by reducing the size of the valve hole provided in the fiber-reinforced resin rim, it is possible to suppress the decrease in strength of the fiber-reinforced resin rim compared to the case where the size of the valve hole is large. However, since the size of the valve is determined, if the size of the valve hole is reduced, the valve cannot be installed in the valve hole. Furthermore, by increasing the thickness of the bearing surface portion provided around the valve hole of the fiber-reinforced resin rim, the strength of the fiber-reinforced resin rim can be prevented from decreasing. However, since the thickness of the bearing surface portion around the valve hole has been determined, if the thickness of the bearing surface portion around the valve hole becomes larger, the valve cannot be installed in the valve hole. Therefore, it is difficult to provide a valve hole in the fiber-reinforced resin rim while ensuring the strength of the fiber-reinforced resin rim and reducing the wall thickness of the fiber-reinforced resin rim.

For the rims with fiber-reinforced resin rims, the structure of the valve hole is designed in order to ensure strength and make it lighter. Specifically, the inventors thought of the following configuration.

The rim according to an embodiment of the present invention is a rim used in a vehicle. The rim is provided with: a ring-shaped fiber-reinforced resin rim that supports the tire and contains fiber-reinforced resin obtained by fiber-reinforced resin; a hub, which is located at the center of rotation; and a valve, which allows gas to flow into the ring Is formed in the annular space between the fiber-reinforced resin rim and the tire mounted on the fiber-reinforced resin rim; the fiber-reinforced resin cavity portion has a boundary wall portion made of fiber-reinforced resin, fibers A wall portion and a partition space made of a reinforced resin, the boundary wall portion made of a fiber reinforced resin constitutes a part of the rim made of the fiber reinforced resin, the wall portion made of the fiber reinforced resin is connected to the rim made of the fiber reinforced resin, the The partition space is formed by the boundary wall portion made of the fiber-reinforced resin and the wall portion made of the fiber-reinforced resin; and a connecting portion that connects the hub and the cavity of the fiber-reinforced resin in the radial direction. The fiber-reinforced resin chamber portion is provided with a vent hole at the boundary wall portion made of the fiber-reinforced resin portion, and the vent hole connects the partitioned space of the fiber-reinforced resin chamber portion to the annular space or the outside. The wall portion made of fiber-reinforced resin is provided with a valve mounting hole for mounting the valve.

By this means, a rim provided with a fiber-reinforced resin rim containing fiber-reinforced resin can be provided at the boundary wall of the fiber-reinforced resin rim even when a force is applied to the rim in the radial direction The peripheral part of the vent hole of the part ensures the strength.

That is, when a force is applied to the rim in the radial direction, a portion of the rim that supports the tire receives a force such that the tip portion is displaced in the radial direction. In the configuration in which the valve hole for mounting the valve is provided on the rim, the strength of the peripheral portion of the valve hole is reduced. Therefore, when the rim receives the force as described above, the peripheral portion of the valve hole may be deformed. In particular, when the rim is a fiber-reinforced resin rim containing fiber-reinforced resin obtained by fiber-reinforced resin, the fiber is cut at the peripheral portion of the valve hole, so the peripheral portion of the valve hole The intensity is further reduced.

In view of this, in the above configuration, a fiber-reinforced resin-made chamber portion having a partition space formed by a fiber-reinforced resin-made boundary wall portion and a fiber-reinforced resin-made wall portion partition is provided, and the fiber-reinforced resin-made boundary wall portion It constitutes a part of the fiber-reinforced resin rim and defines the annular space between the fiber-reinforced resin rim and the tire, and the fiber-reinforced resin wall extends radially inward from the fiber-reinforced resin rim . In addition, a vent hole connecting the partition space and the annular space is provided at the boundary wall portion of the fiber-reinforced resin rim. In addition, a valve mounting hole is formed in the wall portion made of the fiber-reinforced resin, which connects the partitioned space and the outside and penetrates the valve. In this way, strength can be ensured at the peripheral portion of the vent hole. Thereby, even when the above-mentioned fiber-reinforced resin rim is subjected to the aforementioned force, it is possible to prevent the structure change of the above-mentioned fiber-reinforced resin rim.

In addition, the fiber-reinforced resin rim includes fiber-reinforced resin obtained by fiber-reinforced resin, and therefore, it can be made lighter than a metal rim.

Therefore, with the above-mentioned configuration, it is possible to obtain a configuration in which the rim can be reduced in weight while ensuring strength.

According to another aspect, the rim of the present invention preferably includes the following configuration. The wall portion made of the fiber-reinforced resin is an annular ring formed by connecting the fiber-reinforced resin rims in the circumferential direction.

The vent hole penetrates the boundary wall portion made of the fiber-reinforced resin in the radial direction, and connects the annular space and the partition space.

Accordingly, even when a force is applied to the fiber-reinforced resin rim in the radial direction, it is possible to prevent a large force from being applied to the peripheral portion of the valve mounting hole. Thus, the strength of the rim can be improved.

According to another aspect, the rim of the present invention preferably includes the following configuration. The fiber-reinforced resin wall portion has a fiber-reinforced resin longitudinal wall portion extending from the fiber-reinforced resin rim toward the inner side in the radial direction.

Furthermore, the cross-sectional view of the rear wheel rim 41 in FIG. 2 is the same as FIG. 4. The configuration of the rear wheel rim 41 will be described below.

The vehicle 1 is, for example, a locomotive, and includes a vehicle body 2, a front wheel 3, and a rear wheel 4. The vehicle body 2 supports various components such as the front wheel 3, the rear wheel 4, the handle 6, the seat 7 and the power unit 8. In this embodiment, the vehicle body 2 includes a frame 10, a pair of front forks 15, and a rear arm 16.

The frame 10 has a head pipe 11 and a main frame 12. The head pipe 11 is located at the front of the vehicle 1 and rotatably supports a steering shaft (not shown) connected to the handle 6. The main frame 12 is connected to the head pipe 11 so as to extend from the head pipe 11 toward the rear of the vehicle. The main frame 12 supports a power unit 8 and the like.

The frame 10 may include a metal material or a fiber-reinforced resin obtained by reinforcing the resin with fibers such as carbon fiber.

A pair of front forks 15 are disposed to the left and right of the front wheel 3, and extend upward and rearward from the front wheel 3. The upper end of each front fork 15 is connected to the handle 6. The lower end of each front fork 15 rotatably supports the front wheel 3.

The rear arm 16 extends from the rear of the main frame 12 toward the rear. The front end of the rear arm 16 is rotatably connected to the rear of the main frame 12 in the up-down direction. The rear end of the rear arm 16 rotatably supports the rear wheel 4. Furthermore, the rear arm 16 and the main frame 12 are connected by the rear suspension 17.

The front wheel 3 has a front wheel rim 31 and a front wheel tire 32. The front wheel rim 31 is rotatably supported by the lower ends of the pair of front forks 15. In this embodiment, the front wheel rim 31 is the same as before, for example, a metal rim. The front wheel tire 32 is arranged on the outer peripheral surface of the front wheel rim 31.

A front wheel brake disc 33 that constitutes a part of the front wheel brake is attached to the front wheel rim 31 at the center of rotation. The front wheel brake disc 33 is disc-shaped and rotates together with the front wheel rim 31. Furthermore, on the outer peripheral portion of the front wheel brake disc 33, a front wheel caliper 34 for holding the front wheel brake disc 33 during the operation of the front wheel brake is arranged.

The rear wheel 4 has a rear wheel rim 41 (rim) and a rear wheel tire 42 (tire). The rear wheel rim 41 is rotatably supported on the rear end of the rear arm 16. In the present embodiment, the rear wheel rim 41 contains carbon fiber reinforced resin obtained by resin reinforcement with carbon fiber. The rear tire 42 is arranged on the outer peripheral surface of the rear wheel rim 41.

On the rear wheel rim 41, a rear wheel brake disc 43 that forms part of the rear wheel brake is also installed at the center of rotation. The rear wheel brake disc 43 is disc-shaped and rotates together with the rear wheel rim 41. In addition, like the front wheel 3, the rear wheel caliper 44 that holds the rear wheel brake disk 43 during the operation of the rear wheel brake is disposed on the outer peripheral portion of the rear wheel brake disk 43.

<Rear Wheel Rim> Next, the specific configuration of the rear wheel rim 41 will be described using FIGS. 3 and 4. FIG. 3 is a perspective view showing a schematic configuration of the rear wheel rim 41. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3.

As shown in FIGS. 3 and 4, the rear wheel rim 41 has a circular shape as viewed from the axis direction of the rotation axis R located at the rotation center of the rear wheel 4. The rear wheel rim 41 is arranged so that the center is aligned with the rotation axis R when viewed from the above-mentioned axis direction. Furthermore, the axis direction of the rotation axis R of the rear wheel 4 coincides with the left-right direction of the vehicle 1.

The rear wheel rim 41 has: a hub 50 located at the center of rotation of the rear wheel 4; an annular rim 60 (fiber-reinforced resin rim) located at the radial outer periphery of the rear wheel rim 41; a chamber A portion 80 (a fiber-reinforced resin cavity portion) located radially inward of the rim 60; and a coupling portion 70 that couples the hub 50 and the cavity portion 80. After this embodiment, the wheel rim 41 is a so-called disk rim in which the connecting portion 70 is a disk.

The hub 50 is located at the center of rotation of the rear wheel rim 41. As shown in FIG. 4, the hub 50 has a left hub portion 51 and a right hub portion 52. The left hub portion 51 is located further left than the center of the rear wheel rim 41 in the left-right direction. The right hub portion 52 is located further to the right than the center in the left-right direction. The left hub portion 51 and the right hub portion 52 are respectively annular and plate-shaped, and are arranged so that the thickness direction coincides with the above-mentioned left-right direction.

The left hub connection member 53 is connected to the left hub portion 51 and the left side portion. The right hub connection member 54 is connected to the right hub portion 52 and the right side portion. The left-hand hub connecting member 53 and the right-hand hub connecting member 54 are respectively disc-shaped, and are attached to the hub 50 so that the thickness direction coincides with the above-mentioned left-right direction. The left-hand hub connecting member 53 and the right-hand hub connecting member 54 are connected in the left-right direction by a connecting tube 55 inserted through the hub 50. An axle (not shown) is inserted into the connecting tube 55. As a result, the hub 50 is rotatably supported by an axle (not shown) via the left hub connection member 53, the right hub connection member 54 and the connection tube 55.

Although not specifically shown, a sprocket meshing with a chain that transmits power of the power unit is attached to the right hub connecting member 54. With this, the power of the power unit is transmitted to the rear wheel rim 41 via the chain.

In the present embodiment, the left hub connecting member 53, the right hub connecting member 54 and the connecting tube 55 are made of metal, respectively.

The coupling portion 70 is formed in a cross-sectional view of the rear wheel rim 41 in the radial direction, and the width gradually narrows from the hub 50 toward the chamber portion 80. That is, the coupling portion 70 is viewed in the above-mentioned radial section, and the width of the coupling portion with the chamber portion 80 is smaller than the width of the coupling portion with the hub 50. Thereby, the rear wheel caliper 44 can be arranged to the right of the connecting portion 70 and the connecting portion of the chamber portion 80. Thereby, the rear wheel caliper 44 can be compactly arranged on the rear wheel 4 in the left-right direction.

In detail, the connecting portion 70 has a left connecting portion 71 and a right connecting portion 72. The left connecting portion 71 connects the left hub portion 51 and the chamber portion 80. The right connecting portion 72 connects the right hub portion 52 and the chamber portion 80. The left connecting portion 71 and the right connecting portion 72 are plate-shaped, respectively, and are arranged so that the distance from the hub 50 toward the chamber portion 80 becomes narrower as viewed in a radial cross section of the rear wheel rim 41. A space is formed between the left connecting portion 71 and the right connecting portion 72.

The rim 60 is viewed in the radial section of the rear wheel rim 41 and extends from the center of the rear wheel rim 41 in the left-right direction to the left-right direction. That is, the rim 60 has a left rim portion 61 that extends from the center in the left-right direction to the left and the radial outer side; and a right rim portion 62 that extends from the center in the left-right direction to the right and the diameter Extend outward. In the rim 60, the left rim portion 61 and the right rim portion 62 are integrally formed. In the rim 60, the connecting portion of the left rim portion 61 and the right rim portion 62 is recessed toward the inner side in the radial direction.

The left rim portion 61 is viewed in the above-mentioned radial cross section, and protrudes further left than the connecting portion 70. The right rim portion 62 is viewed in the above-mentioned radial cross section, and protrudes further to the right than the connecting portion 70. The left rim portion 61 and the right rim portion 62 are viewed in a cross-section in the radial direction, and are bilaterally symmetrical.

The rear tire 42 is arranged radially outward of the left rim portion 61 and the right rim portion 62. Specifically, the inner peripheral portion of the rear tire 42 is in contact with the radially outer peripheral portion of the left rim portion 61 and the right rim portion 62. Thereby, an annular space S extending annularly along the rim 60 is formed between the rim 60 and the rear tire 42.

The left rim portion 61 has a protrusion 61a protruding radially outward at the left end. The right rim portion 62 has a protrusion 62a protruding radially outward at the right end. That is, the protruding portions 61a and 62a are located at both ends of the rim 60 in the left-right direction. The inner peripheral portion of the rear tire 42 is in the left-right direction, and is disposed between the protruding portion 61a and the protruding portion 62a of the rim 60.

The rear wheel rim 41 includes carbon fiber-reinforced resin obtained by reinforcing resins (for example, epoxy resin, vinyl ester, phenol resin, polyamide, polypropylene, polyphenylene sulfide, etc.) with carbon fibers. In this embodiment, the carbon fiber includes a plurality of fiber sheets stacked in the thickness direction. The stacking direction of the fiber sheet (fiber) is the thickness direction of each wall constituting the rear wheel rim 41. The above-mentioned fiber sheet means a member in which fibers are formed into a thin sheet (planar shape) by weaving or reinforcement, for example.

In the present embodiment, the hub 50, the rim 60, the coupling portion 70, and the chamber portion 80 include carbon fiber resin. In addition, the hub 50, the rim 60, the coupling portion 70, and the chamber portion 80 are integrally formed.

In the above configuration, as shown in FIG. 5, when a force is input to the rear wheel tire 42 in the upward direction (the hollow arrow in FIG. 5 ), the rear wheel tire 42 is input toward both ends of the rim 60 in the left-right direction Force (solid arrows in Figure 5). That is, upward force is input to the left end of the left rim 61 and the right end of the right rim 62. As a result, tensile stress is generated in the central portion of the rim 60 in the left-right direction.

Generally speaking, a valve for supplying air in the annular space between the rim and the rear tire is installed on the rim. Therefore, a through hole for mounting the valve is formed in the rim. As described above, in the case of including the carbon fiber reinforced resin obtained by carbon fiber reinforcement of the resin and then the wheel rim 41, the portion where the through hole for mounting the valve is provided in the rim is cut off the carbon fiber. Therefore, the peripheral portion of the through hole in the rim is lower in strength than the portion without the through hole. In such a configuration, as described above, when a force is input from the rear wheel tire to both ends of the rim in the left-right direction, there may be a case where sufficient strength cannot be obtained for the rim.

In view of this, in the present embodiment, only the vent hole 81 a is provided in the rim 60 instead of directly mounting the valve on the rim 60, and the valve 90 is installed on the chamber portion 80 located on the radially inner side of the rim 60.

In detail, the rear wheel rim 41 is radially inward of the rim 60 and has a cavity portion 80 between the central portion of the rim 60 in the left-right direction and the coupling portion 70. As shown in FIG. 4, the chamber portion 80 has: a boundary wall portion 81 that constitutes the central portion of the rim 60 in the left-right direction and partitions a part of the annular space S; a pair of wall portions 82, 83 (vertical wall portion ), etc. extend radially inward from the rim 60; and the connecting wall portion 84, which connects the wall portions 82, 83 to each other. The chamber portion 80 has a partition space P formed by partitioning the boundary wall portion 81, the wall portions 82, 83, and the connection wall portion 84. That is, the rear wheel rim 41 is provided with the partition space P between the rim 60 and the coupling portion 70. Furthermore, the partition space P may be formed annularly on the radially inner side of the rim 60 of the rear wheel rim 41 over the entire circumference of the circumferential direction, or may be formed only on a part of the circumferential direction.

By arranging the cavity portion 80 as described above on the radially inner side of the rim 60, the profile factor can be increased in the radial profile of the rear wheel rim 41. Thus, the strength of the rear wheel rim 41 can be improved.

The boundary wall portion 81 includes the right end portion of the left rim portion 61 and the left end portion of the right rim portion 62 in the rim 60. The boundary wall portion 81 is located in a portion of the rim 60 that is recessed toward the inner side in the radial direction.

The pair of wall portions 82 and 83 are arranged in parallel in the left-right direction. The pair of wall portions 82 and 83 have the same radial dimension. In addition, the radial dimension of the pair of wall portions 82 and 83 is larger than the distance between the pair of wall portions 82 and 83. Thus, the dimension of the division space P of the chamber portion 80 in the radial direction is larger than the dimension in the left-right direction. Thereby, the strength of the chamber portion 80 can be increased in the radial direction of the rear wheel rim 41. Thus, the radial strength of the rear wheel rim 41 can be increased.

The pair of wall portions 82 and 83 are formed in a circular ring shape connected along the rim 60 in the circumferential direction. As a result, the wall portions 82 and 83 that define the partition space P together with the boundary wall portion 81 and the connecting wall portion 84 have sufficient strength in the circumferential direction and the radial direction of the rim 60. Thus, the strength of the chamber portion 80 can be ensured.
