【発明の詳細な説明】
本発明は鋳造製の車輪に関し、さらに詳しくは自動二輪
車等のモータサイクル用として好適な鋳造製車輪に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cast wheel, and more particularly to a cast wheel suitable for use in motorcycles such as motorcycles.
ワイヤスポークからなる車輪の場合は、ワイヤスポーク

ークが一体に鋳造成形されているため高い剛性を有し、
ワイヤスポーク車輪のような緩衝性はもっていない。In the case of wheels made of wire spokes, the bending of the wire spokes has the function of buffering shocks from the road surface. However, cast wheels have high rigidity because the spokes that connect the hub and rim are integrally cast.
They do not have the cushioning properties of wire spoke wheels.
本発明の目的は、鋳造製でありながら優れた緩衝性を有
するようにした車輪を提供せんとすることにある。An object of the present invention is to provide a wheel that is made of cast material but has excellent cushioning properties.

曲させたことを特徴とするものである。A wheel according to the present invention that achieves the above object is characterized in that a hub, a rim, and spokes are integrally cast and formed, and the lli surface shape of the spokes, which has a vertical cross section including the axle divided by G÷, is bent in the axle direction. That is.
以下、本発明を図に示す実施例により説明する。The present invention will be explained below with reference to embodiments shown in the drawings.

A brake disc 4 is fixed on one side. Also, front F A
A caliper 5 is fixed to the brake lever 3 for pinching the brake disc 4.

動ディスク４を跨いでいる。As shown in Fig. 2.3, the front wheel l has a hub 6 supported by the axle, a rim 7 on which the tire is mounted, and spokes 8 connecting the hub 6 and the rim 7 made of magnesium alloy.
It is integrally cast and formed from a light alloy such as aluminum alloy. In a longitudinal section including the axle, the spokes 8 have a cross-sectional shape extending from a connection part with the hub 6 to a connection part with the rim 7, which is largely bent toward the axle direction. A brake disc 4 is fixed to the outer circumference of the hub 6 by bolts 9 on the side where the bent portions of the spokes 8 are concave. The caliper 5 fixed to the front fork 3 has approximately half of its body inserted into the concave side of the bent portion of the spoke 8, and straddles the brake disc 4 at a position as close as possible to the center C of the rim 7. .

なｆＪｊ撃緩ｉｉｉ性を発揮することができる。When the front wheel 1 described above receives an impact from the road surface, the spokes 8 move while moving the rim 7 in the axle direction as shown in FIG.
Since the spokes are bent like 8", it is possible to absorb the impact from the road surface.As a configuration that does not generate such bending of the spokes, a cast wheel shown as a comparative example in Fig. 8 is used. As shown in FIG. 81, the spokes 88 connecting the hub 8G and the rim 87 can be bent in side view.However, in the case of this FIG. are connected and fixed to each other by the rim 87 and have a generally rhombic shape as a whole, so the rim 87 acts to prevent the spokes 88 from deflecting.Therefore, the spokes 8 of the front wheel 1 are free from any deflection. /:L-4' can not be done, and the buffer 1! [is 11
;It is impossible to make it as large as 1 wheel. That is, in the case of the front wheel I, as shown in FIG. iii).

ことができる。Also, 1. On the above-mentioned J and S layer sides, the caliper 5 and brake disc 4 are closer to the -jH rim center C side compared to the subordinate J-'Tsukiyo wheel. -U, one verticality can be directed -1- to that one. Manoko Caliper 5 arrangement: 1 U: wo ;); 1 Fume 3
Since it is easy to locate the shortest position as close to the center of rotation (steering axis) as possible, the inertia around the four axes can be reduced, and from this point of view as well, the verticality of the JRFit can be improved. I can do it.

備えることができる。Furthermore, since the braking device is in a protected state inserted inside the rim 7, damage caused by flying stones and dirt caused by mud can be reduced. In addition, since the spokes 8 have a flexible shape, they are easily deflected by impact, and can also provide impact cushioning properties.

に配置されている。4 to 6 show other embodiments, respectively. In these embodiments, the brake disc 4 and caliper 5 are moved closer to the rim center C side than in the first embodiment. \ In the embodiment shown in Fig. 4, the connecting portions 8a of the spokes 8 to the hub 6 are vertically extended in the radial direction at the rim center C, and then bent approximately at right angles to the axle direction to extend in the axle direction. The main body of the spoke 8 is bent in the axle direction from the lateral extension portion as described above. This connecting part 8a
Therefore, the brake disc 4 and caliper 5 are located approximately at the rim center C.
It is located in

近く配置できるようにしている。In each of the embodiments shown in FIGS. 5 and 6, the connecting portions 8a of the spokes B to the no-pro are biased toward the side ends of the no-pro, and the space at the rim center C is increased due to the biased configuration of the connecting portions 8a. This makes it possible to locate the braking device closer to the rim center C.
したがって、これら第４〜６図の実施例の車輪は、上記
第１の実施例同様の衝撃緩衝性と共に、さらに碌向輪と
して大幅な操縦性向上を図ることができる。Therefore, the wheels of the embodiments shown in FIGS. 4 to 6 have the same impact-absorbing properties as the first embodiment, and can also be used as powerful wheels to significantly improve maneuverability.

ゲζ同様の効果を奏することができる。In addition, in the above-mentioned example, the description was made using 1v for the front wheel, but
The present invention can also be applied to the rear wheels, and the same effects as the gears ζ can be achieved by the same configuration as the front wheels.

ポークが撓み、その衝撃を緩ｊＩｊすることができる。As mentioned above, the wheel of the present invention has a knob, a rim, and spokes formed by casting into a body, and a vertical frame including an axle.
Since the 1v1 surface shape of the spokes extending from the surface is bent in the axle direction, the spokes bend due to the impact from the road surface, and the impact can be softened.
