Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a side stand device for a two-wheeled motor vehicle, and particularly to a side stand device of a type in which a side stand is attached to a swing arm for supporting a rear wheel.

(Prior art) Conventionally, in a type of vehicle in which a side stand is attached to a swing arm, a bracket is fixed to the swing arm, and a pin for connecting the support shaft and return spring of the side stand is fixed to the bracket. .

Further, when the side stand is flipped up (stored state), the side stand is generally located outside the swing arm and is visible from the outside. As a prior art, there is Japanese Patent Application Laid-Open No. 57-77277.

(Problem to be solved by the invention) In this way, in the conventional structure, the side stand is exposed to the outside even in the retracted state, so
There is a problem that the overall appearance of the vehicle deteriorates.

Furthermore, in order to attach the side stand, it is necessary to fix a special bracket to the swing arm by welding or the like, which increases part costs and assembly costs.

(Means for solving the problem) In order to solve the above problem, the present invention arranges a side stand near the swing arm for supporting the rear wheel, and connects the support shaft to the base end of the side stand with the swing arm. One end of the return spring for supporting and storing the side stand is connected to the middle part of the side stand, and the other end of the return spring is connected to the spring connecting part fixed to the swing arm.
In the side stand device for a wheeled vehicle, the support shaft and the spring connection portion are directly attached to the swing arm itself, and a recessed space in which the support shaft and the spring connection portion, the side stand in a retracted state, and the return spring are housed is provided in the swing arm itself. It is characterized by the fact that it has been established.

(Function) According to the above structure, the side stand is stored in the recessed space of the swing arm,
Since the side stand in the retracted state is not visible from the outside, the appearance is improved.

(Embodiment) FIG. 1 is a schematic left side view of an apparatus according to an embodiment of the present invention. In FIG. 1, a swing arm 1 extending approximately in the longitudinal direction of the vehicle body (left-right direction in FIG. 1) is provided with a bearing portion 2 at its front end and an axle support portion 3 at its rear end. The bearing part 2 is a support shaft in the vehicle width direction (not shown)
It is rotatably supported by the vehicle body frame (not shown) via. The axle support part 3 supports the axle of a rear wheel (not shown).

In the state shown by the solid line in FIG. 1, the side stand 5 is in an operating state (a state in which it supports the vehicle body), and extends downward and slightly forward from the front portion of the swing arm 1. The upper end of the side stand 5 is rotatably supported by the swing arm 1 via a support shaft 6 extending generally in the vehicle width direction. Spring receiving pins 7 and 8 are attached to the upper part of the swing arm 1 and the side stand 5, and both ends of a return spring 10 (tension coil spring) are hooked to these spring receiving pins 7 and 8. Furthermore, the swing arm 1 is also provided with a stopper 11 for preventing the side stand 5 from rotating forward beyond the illustrated operating position.

In FIG. 2, which is a cross-sectional view of FIG. 1,
The swing arm 1 is made of extruded material and integrally includes a hollow structure having a rectangular cross section and a pair of side walls 12 and 13 that extend downward from both left and right walls of the hollow structure. , 13 is formed with a recessed space 15 for storing the side stand. In the operating state shown in FIG. 2, the side stand 5 has its upper end inserted into the space 15, and is supported by the support shaft 6 in this state.

The support shaft 6 is formed of a bolt, and both ends thereof are fitted into holes in the side walls 12 and 13 to be fixed.
Further, the support shaft 6 extends in a direction perpendicular to the direction of inclination of the side stand 5, and extends toward the center of the vehicle body (side wall 13).
The end portion on the side) is located at a lower position than the end portion on the outside of the vehicle body (side wall 12 side). The head of the support shaft 6 enters a counterbore hole 16 formed in the side wall 12, and the support shaft 6
A nut 17 fixed to the side wall 13 enters a counterbore 18 formed in the side wall 13.

The spring receiving pin 7 for the return spring 10 is fixed to the side wall 13 by welding or press-fitting, and projects into the space 15 above the support shaft 6.

As shown in FIG. 1, the return spring 10 extends vertically behind the support shaft 6 along the side stand 5 when the side stand 5 is in the operating position, and is housed inside the side stand 5 as follows. There is. As shown in FIG. 3, which is a cross-sectional view of FIG.
It has a space 20 open to the right in the figure, and the return spring 10 is accommodated in the space 20.

In FIG. 1, the side stand 5 is flipped up rearward about the support shaft 6, and the side stand 5
It is in the retracted position shown by the dotted chain line, and the hook 22 at the rear end is
The entire body except for the space 15 is accommodated in the space 15. Hook 22
forms a landing surface in the operating state, and is used to lower the side stand 5 to the operating position by hooking it with your foot in the retracted state. It's sticking out.

In the retracted position, the side stand 5 extends rearward from the front end at an angle slightly outward in the vehicle width direction, but since the swing arm 1 itself also extends in the same direction, the entire portion of the side stand 5 other than the hook 22 extends into the space 15. Stored.

The stopper 11 is also fitted into the front end of the space 15.

(Effect of the invention) As explained above, according to the invention, the side stand 5 is accommodated in the space 15 of the swing arm 1 in the retracted state, so that the appearance of the side stand 5 and the swing arm 1, and by extension the appearance of the entire vehicle, is improved. be able to. Further, since there is no need to fix a special bracket for attaching the side stand 5 to the swing arm 1, parts costs and assembly costs can be reduced.
