この発明は、片持式の前ホークを用いた自動二
輪車の前輪保持装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a front wheel holding device for a motorcycle using a cantilevered front fork.

前輪を取付ける所謂片持式の前ホークが用いられ
る。この前ホークは部品点数も少く安価にでき

りしなければならない不都合ができる。 Generally, on a motorcycle, both ends of the axle that rotatably supports the front wheel are held at the lower ends of the left and right front forks, but two forks are required on the left and right, which increases the number of parts, making it difficult to use for small and inexpensive motorcycles. is not suitable. In small-sized motorcycles, a so-called cantilever type front fork is used in which a single front fork is placed to one side and the front wheel is attached to an axle fitting at the lower end of the front fork. The previous Hawk has fewer parts and can be made cheaper. However, the left and right weight of the front wheels becomes heavier on the front fork side, creating an imbalance, causing the front wheels to cut into the heavier side, making it difficult to drive straight. This results in the inconvenience of having to adequately support the handlebars or shift one's weight to a lighter side.

バー角Ｃを持たせるように傾斜させて設ける。 The front fork 1 is rotatably supported by a head pipe 2 at the front end of the vehicle body, and its lower part is bent laterally from the center 3 of the head pipe 2 and placed toward the side.
It is a so-called cantilever type hawk. And the front Hawk 1
An axle fitting 4 is swingably supported at the lower end of the
A suspension unit 5 is connected to an arm extending to the rear side of the axle fitting 4 so as to be able to swing. The axle fitting 4 rotatably holds the front wheel 6. Therefore, the present invention has a structure in which the axle fitting 4 is aligned with the front wheel 6 relative to the center line 3 of the head pipe 2.
It is provided so that the lower side thereof is located on the front fork 1 side and is inclined to have a camber angle C.
作用について説明する。 The effect will be explained.
前ホーク１は、前輪６の片側に設けられている

この矢印Ａの力に対応して、前輪６を逆側（矢印

前輪６を傾斜させてキヤンバー角Ｃを設けること

角Ｃでよい。 Since the front fork 1 is provided on one side of the front wheel 6, the front wheel 6 tends to bend toward the front fork 1 side (indicated by arrow A). The camber angle C is
Corresponding to the force of arrow A, a force is generated to bend the front wheel 6 in the opposite direction (indicated by arrow B). thus,
By tilting the front wheels 6 to provide the camber angle C, the force of arrow A and the force of arrow B due to the camber angle C are balanced, and the straightness of the front wheels 6 can be maintained. In the figure, for convenience of explanation, the front wheels 6 are shown to be tilted significantly and the camber angle C is increased, but in reality, the camber angle C may be extremely small.

ど判らない。 As explained above, the present invention, in which the front wheel is attached to one side of a single front fork, tilts the axle fitting of the front fork to center the head pipe that rotatably supports the front fork. Since the front wheel is held at a camber angle so that the lower side of the front wheel is located on the front fork side with respect to the line, the force that tries to bend the front wheel due to weight imbalance,
The camber angle balances out the forces that bend the front wheels in the opposite direction, making it possible to maintain the straightness of the front wheels, improving maneuverability. Also, the camber angle is
It is only slight, and uneven wear on the front tires is hardly noticeable.
