< wheel >
Next, the structure of the wheel 20 of the front wheel 3 and the rear wheel 4 of the motorcycle 1 will be described. The wheel structure of the embodiment is applied to both the front wheel 3 and the rear wheel 4, but may be applied to either.
As shown in fig. 2 and 3, the wheel 20 includes a hub portion 21 through which an axle passes, an annular rim portion 22 on which a tire is mounted, and a plurality of (12 in the figure) spoke portions 23 spanning between the rim portion 22 and the hub portion 21. The wheel 20 is a cast wheel in which a rim portion 22, a hub portion 21, and a plurality of spoke portions 23 are integrally formed with each other, and is formed of a light alloy such as an aluminum alloy.
Hereinafter, the axial direction of the wheel 20 (the vehicle width direction in a state of being mounted on the vehicle) may be referred to as a wheel axial direction, the radial direction of the wheel 20 as a wheel radial direction, and the circumferential direction of the wheel 20 as a wheel circumferential direction. A line CW in the drawing indicates a rotation center axis of the wheel 20, and an arrow F indicates a forward rotation direction (a rotation direction when the vehicle travels) in a state where the wheel 20 is mounted on the vehicle.
The hub portion 21 includes: a cylindrical hub main body 31 extending in the wheel axial direction along the center axis CW of the wheel 20; and a cylindrical outer peripheral wall portion 32 formed in an annular shape coaxial with the hub main body 31 and formed at a distance from the outer peripheral side of the hub main body 31.
The hub body 31 has wheel bearings (not shown) press-fitted into both ends in the wheel axial direction, and is rotatably supported by the axle via the wheel bearings.
The outer peripheral wall portion 32 is connected to the hub main body 31 via a plurality of (4 in the figure) connecting wall portions 33 and is supported by the hub main body 31. The plurality of connecting wall portions 33 are provided apart from each other in the wheel circumferential direction. The weight reduction of the hub portion 21 is achieved by such a double wall structure.
The gap between the outer peripheral wall portion 32 and the hub main body 31 is closed at one side in the vehicle width direction (the right side in the embodiment, the rear side in fig. 2). The gap portion is divided by a plurality of connecting wall portions 33 in the wheel circumferential direction, and a plurality of concave portions 34 are formed so as to be recessed in the vehicle width direction. Each recess 34 is open toward the other side in the vehicle width direction (the left side in the embodiment, the front side in fig. 2). Thus, the outer peripheral wall portion 32 is separated from the hub main body 31 to reduce the weight of the hub portion 21, and the outer peripheral wall portion 32 and the hub main body 31 are coupled to each other via the plurality of coupling wall portions 33 to secure the strength of the hub portion 21.
Each of the connecting wall portions 33 has an inner circumferential boss portion 35 for mounting a pulse ring 17 (see fig. 4) of the wheel speed sensor. The inner peripheral boss portion 35 is formed parallel to the wheel axial direction. The inner peripheral boss portion 35 is provided on the connecting wall portion 33 to secure strength.
The plurality of spoke portions 23 are arranged at unequal intervals in the wheel circumferential direction.
Here, the outer peripheral wall portion 32 includes a plurality of (4) convex portions 36 that protrude outward from the outer peripheral side thereof. The plurality of convex portions 36 are provided apart from each other in the wheel circumferential direction. A plurality of (3) spoke portions 23 extend from each of the convex portions 36 toward the outer peripheral side of the wheel 20. Hereinafter, a group of the plurality of spoke portions 23 corresponding to each of the convex portions 36 may be referred to as a spoke group 23A.
The convex portion 36 is formed in a substantially trapezoidal shape as viewed in the wheel axial direction, and protrudes outward from the outer peripheral side of the outer peripheral wall portion 32, while suppressing the width in the wheel axial direction with respect to the hub portion 21. The base end portions of the plurality of spoke portions 23 on the inner side in the wheel radial direction are connected to the tip end side (top side) of the outer peripheral portion 36a of the convex portion 36 as viewed in the wheel axial direction.
An outer peripheral boss portion 37 for attaching the brake disk 18 (see fig. 4) of the brake device is formed on the convex portion 36. The outer peripheral boss portion 37 is formed parallel to the wheel axial direction. The outer circumferential boss portion 37 is provided on the convex portion 36 connecting the plurality of spoke portions 23, whereby strength can be secured as compared with the case where the boss portion is provided on a single spoke portion 23.
The outer circumferential boss portion 37 is provided at a position where the wheel circumferential position overlaps the inner circumferential boss (the connecting wall portion 33). In this regard, the strength of the outer peripheral boss portion 37 can also be ensured. The outer-peripheral boss portion 37 has a larger diameter than the inner-peripheral boss portion 35 and is positioned on the outer side in the wheel radial direction than the inner-peripheral boss portion 35, and the outer-peripheral boss portion 37 protrudes to the other side in the vehicle width direction (the left side in the embodiment, the front side in fig. 2) than the inner-peripheral boss portion 35.
Referring to fig. 2, the plurality of spoke portions 23 are inclined so as to be positioned on one side in the wheel circumferential direction (for example, on the opposite side in the rotational direction F) on the outer circumferential side of the wheel 20 with respect to a radial line k that passes through the base end and the center axis CW of each spoke portion 23 and that extends in the wheel radial direction. The plurality of spoke portions 23 are inclined to the same side in the wheel circumferential direction. Each of the spoke portions 23 extends substantially linearly in a side view. Reference lines along the extending direction of the spoke portions 23 are referred to as C1, C2, and C3 in this order from the spoke portion 23 on the downstream side in the rotation direction F. Reference lines C1, C2, and C3 are straight lines extending from the outer peripheral edge of the convex portion 36 to the inner peripheral edge of the rim portion 22. Each spoke portion 23 may extend with a curvature in a side view. In this case, the reference lines C1, C2, and C3 may be straight lines connecting both ends.
Angles θ 1, θ 2, and θ 3 of the reference lines C1, C2, and C3 with respect to the radial line k are sequentially increased from the downstream side in the rotation direction F (θ 1 < θ 2 < θ 3). The lengths of the reference lines C1, C2, and C3 (corresponding to the lengths of the spoke portions 23) L1, L2, and L3 are longer in this order from the downstream side in the rotation direction F (L1 < L2 < L3).
Each of the convex portions 36 is provided with a concave portion 38 that is concave in the vehicle width direction at a position adjacent to the outer-peripheral-side boss portion 37 in the wheel circumferential direction and at a position avoiding the outer peripheral portion 36a connecting the spoke portions 23. The recess 38 is open to the other side in the vehicle width direction (the left side in the embodiment, the front side in fig. 2). The connection strength of the spoke portion 23 is ensured by forming the concave portion 38 avoiding the spoke connection portion of the convex portion 36.
The recess 38 is closed with a bottom portion at one side in the vehicle width direction (the right side in the embodiment, the rear side in fig. 2). This ensures strength of the projection 36 while reducing weight by forming the recess 38. The concave portion 38 may be formed as a hole penetrating the convex portion 36 in the vehicle width direction.
The concave portions 38 are provided on both sides in the wheel circumferential direction with the outer circumferential boss portion 37 therebetween, and are used to obtain a weight reduction capacity of the convex portion 36. The recess 38 is substantially shielded when the pulse ring 17 and the brake disk 18 are mounted, and the influence of the recess 38 on the vehicle appearance is suppressed. The outer-peripheral-side boss portion 37 is located substantially at the center of the boss portion 36 in the wheel circumferential direction.
As described above, the wheel structure in the above embodiment is a structure of the cast wheel 20 including the hub portion 21 supported by the axle, the rim portion 22 on which the tire is mounted, and the plurality of spoke portions 23 spanning between the hub portion 21 and the rim portion 22, wherein the hub portion 21 includes the hub main body 31 supporting the bearing, and the annular outer wall portion 32 provided separately from the hub main body 31 on the outer periphery of the hub main body 31, the outer wall portion 32 includes the plurality of protrusions 36 protruding outward from the outer peripheral side thereof, the plurality of spoke portions 23 are divided into the plurality of spoke portions 23 according to a part of the plurality of spoke portions 23 to form the plurality of spoke groups 23A, and the plurality of spoke portions 23 of each of the plurality of spoke groups 23A protrude from each of the plurality of protrusions 36 toward the rim portion 22.
According to this structure, the length of the spoke portion 23 can be reduced by the amount corresponding to the convex portion 36, and the strength of the spoke portion 23 can be effectively ensured.
In the wheel structure in the above-described embodiment, the plurality of spoke portions 23 of each of the plurality of spoke groups 23A are inclined to the same side in the circumferential direction of the wheel 20 with respect to the radial direction of the wheel 20.
According to this configuration, since the plurality of spoke portions 23 of each spoke group 23A extending from each convex portion 36 are inclined toward the same side in the wheel circumferential direction, the load input to the wheel assembly can be easily avoided, and a strong wheel 20 can be formed.
In the wheel structure in the above embodiment, the inclination angles θ 1, θ 2, θ 3 of the plurality of spoke portions 23 of each of the plurality of spoke groups 23A with respect to the radial direction and the lengths L1, L2, L3 from the hub portion 21 to the rim portion 22 are different from each other.
According to this configuration, since the inclination angles θ 1, θ 2, and θ 3 and the lengths L1, L2, and L3 of the plurality of spoke portions 23 of each spoke group 23A are different from each other, the spoke portions 23 suitable for loads and vibrations having different characteristics can be mixed in each spoke group 23A. Therefore, the wheel 20 having a large suitable range for the load and the vibration can be obtained. As compared with the case where the inclination angles and the lengths of the plurality of spoke portions 23 are the same, the design can be improved by providing a change in the appearance of the wheel 20.
In the wheel structure in the above embodiment, the plurality of convex portions 36 are provided with outer-peripheral-side boss portions 37 for attaching the brake disk 18, respectively.
According to this configuration, by providing the outer-peripheral-side boss portion 37 on each convex portion 36, the outer-peripheral-side boss portion 37 having a required strength can be provided with the convex portion 36 as a base.
In the wheel structure in the above embodiment, the hub portion 21 is provided with a plurality of coupling wall portions 33 that couple the hub main body 31 and the outer peripheral wall portion 32 at positions that overlap the outer peripheral boss portion 37 in the circumferential direction of the wheel 20 between the hub main body 31 and the outer peripheral wall portion 32.
According to this configuration, by providing the connecting wall portion 33 between the hub main body 31 and the outer peripheral wall portion 32 at a position overlapping the outer peripheral boss portion 37, the periphery of the outer peripheral boss portion 37 can be reinforced.
In the wheel structure of the above embodiment, the coupling wall portion 33 is provided with an inner peripheral boss portion 35 to which the pulser ring 17 is attached.
According to this configuration, by providing the inner peripheral boss portion 35 with the coupling wall portion 33, the strength of the inner peripheral boss portion 35 can be easily ensured.
In the wheel structure in the above embodiment, the convex portion 36 is provided with a concave portion 38 that is concave in the axial direction of the wheel 20 at a position adjacent to the outer peripheral side boss portion 37 in the circumferential direction of the wheel 20 and at a position avoiding the outer peripheral portion 36a connecting the spoke portions 23.
According to this configuration, by providing the concave portion 38 at a position of the convex portion 36 that avoids the outer peripheral side boss portion 37 and the spoke connecting portion, the convex portion 36 can be effectively reduced in weight and weight.
In the wheel structure in the above embodiment, the recessed portions 38 are provided on both sides sandwiching the outer peripheral side boss portion 37 in the circumferential direction.
Accordingly, the weight of the convex portion 36 can be reduced on both sides of the outer circumferential boss portion 37, and the outer circumferential boss portion 37 can be disposed at a position closer to the center of the convex portion 36 in the wheel circumferential direction, and can be supported in a balanced manner.
< modification example >
Next, a wheel 120 according to a modification of the embodiment will be described with reference to fig. 5. The same components as those in the embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.
The wheel 120 of the modification is different particularly in the structure of the plurality of (4) convex portions 136 on the outer peripheral side of the outer peripheral wall portion 32. The convex portion 136 of the modification has the outer-peripheral-side boss portion 37 disposed at a position closer to one side in the wheel circumferential direction (for example, the upstream side in the rotation direction F). The outer circumferential boss portion 37 is provided at a position where the wheel circumferential position overlaps the inner circumferential boss (the connecting wall portion 33). In other words, the convex portion 136 (and the spoke portion 23) of the modification example is disposed offset to the other side (for example, the downstream side in the rotational direction F) in the wheel circumferential direction with respect to the convex portion 36 (and the spoke portion 23) of the embodiment.
Each of the convex portions 136 is provided with a concave portion 138 that opens to the other side in the vehicle width direction (the left side in the embodiment, the front side in fig. 5) at a position adjacent to the outer-peripheral-side boss portion 37 in the wheel circumferential direction and at a position avoiding the outer peripheral portion 36a of the connecting spoke portion 23. The recessed portion 138 is provided on one side in the wheel circumferential direction (for example, the upstream side in the rotational direction F) with respect to the outer peripheral side boss portion 37, but is not provided on the other side in the wheel circumferential direction (for example, the downstream side in the rotational direction F). The recess 138 is formed to be larger than the recess 38 of the embodiment, thereby increasing the weight reduction volume of the projection 136 as compared with the recess 38 of the embodiment.
The present invention is not limited to the above-described embodiments, and for example, a straddle-type vehicle to which the present invention is applied includes all vehicles on which a driver rides straddling a vehicle body, and includes not only motorcycles (including bicycles with prime movers and scooter-type vehicles) but also three-wheeled (including vehicles with two wheels in addition to one wheel before and one wheel after the other) or four-wheeled vehicles.
