て乗り心地に影響を及ぼすおそれもある。The disc of a disc brake for a motorcycle is generally fixed to the side surface of a shaft-supporting boss portion of a wheel with bolts or the like. However, since this brake disc is a plate-shaped body with a radius of a considerable length from its axis, it bears a considerable weight burden, and the so-called unsprung weight becomes heavy, which may affect ride comfort.

A second boss part is provided on the outer peripheral side of the first boss part for shaft support, and is concentric with the first boss part and spaced apart in the radial direction, and the first boss part and the second boss part are connected to each other. The second boss portion is connected to each other by a plurality of lips that are separated from each other at at least two locations on both ends in the width direction and separated from each other at multiple locations in the circumferential direction, and further includes an annular rib on the side surface of the second boss portion. It is characterized by the fact that it is equipped with a brake disc.

以下、図に示す本発明の実施例により説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to embodiments shown in the drawings.

ニウム合金等により一体に鋳造成形される。The figure shows a front wheel for a motorcycle equipped with a brake disc according to the present invention. In this figure, reference numeral 1 denotes a first boss portion for supporting the axle via a bearing or the like. A second boss portion 2 is provided on the outside of the first boss portion 1 and spaced a certain distance apart from the first boss portion 1 in a concentric manner. The first boss part 1 and the second boss part 2 are separated by a considerable distance to form a large space, and are located at six locations in the circumferential direction and at two locations at both ends in the width direction (axial direction). Total of 122 separated locations
They are connected to each other by ribs 6 at certain points. Also,
A total of eight spokes 5 connect the second boss portion 2 and the rim 4 on which the outermost tire is mounted. The wheel body configured as described above is integrally cast from aluminum alloy or the like.

多数の穴６ａが穿設されている。Brake disc slides 6 are fixed to both side surfaces of the second boss portion 20 via bolts 7 and disc mounting bosses 2a. The outer diameter of the brake disc 6 is the same as the conventional one as it is specified by the standard, but the inner diameter is cut out almost along the inner periphery of the second boss part 2, and the overall diameter is the same as that of the conventional brake disc 6. It has an annular shape. Additionally, along the inner circumferential side of the brake disc 6, excluding the outer circumferential side that is compressed by the friction pad of the brake,
A large number of holes 6a are bored.

になる。On the other hand, the second boss part 2 has a substantially dish-shaped cross-sectional shape, and both sides thereof are shaped into inclined walls 2b, increasing the rigidity of the entire second boss part despite the small cross-sectional area. It is supposed to be done. Further, the inclined wall 2b is positioned to cross the circumferential side surface of the disk mounting boss 2a so as to intersect with the direction of the screw hole. Therefore, even if a circumferential force from the disc 6 is applied to the disc mounting post 2a during brake operation, it will be reliably supported by the inclined wall 2b.

って乗り心地の向上がはかれる。Although the motorcycle wheel configured as described above is equipped with a brake disc 6 of the same outer diameter according to the standard, its shape is annular with a large cutout in the center, and the wheel body also has a first diameter. The boss part 1 and the second boss part 2 are connected by a rib 6, creating a large space, and the ribs 3 are not provided over the entire width of the boss part, but are provided at both ends in the width direction. Due to the separate arrangement, the overall weight is significantly reduced compared to conventional wheels equipped with brake discs of the same outer diameter. Further, as in the embodiment, if a large number of holes 6a are provided in the inner circumferential portion of the brake disc 6 as necessary, further weight reduction can be achieved. Therefore, as a result of this weight reduction, the unsprung weight of the motorcycle becomes lighter, resulting in better road tracking performance and improved riding comfort.

なお、上記実施例ではブレーキディスクを第２のボス部

側だけに設けるシングルディスクとしても差支えない。In the above embodiment, a double disc was described in which the brake disc was provided on both sides of the second boss portion, but a single disc may be provided only on one side.

に寄与することができる。As mentioned above, the motorcycle wheel of the present invention has the following features:
A second boss part is provided on the outer peripheral side of the first boss part for shaft support, and is concentric with the first boss part and spaced apart in the radial direction, and the first boss part and the second boss part are connected to each other. The second boss portion is connected to each other by a plurality of ribs separated from each other at at least two locations on both ends in the width direction and separated from each other at multiple locations in the circumferential direction, and further includes an annular rib on the side surface of the second boss portion. Since it is equipped with a brake disc, the weight of the entire wheel is reduced and the unsprung weight is reduced, contributing to improved ride comfort.
