Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stabilizer for a motorcycle.

In motorcycles, stabilizers have conventionally been arranged in series so that the same load is applied to a pair of front forks disposed on the left and right sides of a front wheel. Conventional stabilizers have mounting seats formed on opposing surfaces of the outer pipes of a pair of front forks, and both ends of the stabilizer are fixed to these mounting seats. For this reason, in vehicle models where the inner pipe is covered with a stabilizer, it is necessary to separate the boot and stabilizer to prevent interference with the stabilizer, and therefore the distance between both front forks must be increased. To prevent this, the mounting seat is positioned above the outer periphery of the front wheel to narrow the distance between the two front forks.

Therefore, the present invention has been made in view of the above points, and is characterized in that a stabilizer mounting seat is formed at the front or rear part of the outer pipe, and the stabilizer is fixed to the mounting seat from the front and rear directions. The objective is to prevent interference between the stabilizer and the boots without increasing the distance between the pair of front forks.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

A pair of front forks 2, 2 are arranged on both sides of a front wheel 1 of a motorcycle. The front fork 2 consists of an inner pipe 3 and an outer pipe 4, and the inner pipes 3, 3 are fixed to a bottom bridge 5 installed above the front wheel 1, and a boot 6 is covered at the bottom of the bottom bridge 5. The outer pipe 4 located below the boot 6 rotatably supports the front wheel 1 at its lower end.

A stabilizer mounting seat 7 is provided at the front of the outer pipe 4. The mounting seat 7 is arranged radially inward from the outer periphery of the front wheel 1 (that is, from the axle 8). The stabilizer 9 is attached to the mounting seats 7, 7 from the front with two bolts 1, respectively.
It is fixed at 0.10. These two bolts 10, 10 are attached to the axis 4a of the outer pipe 4 in a distributed manner in the direction of the axle 8, as shown in FIG.

In this way, stabilizer 9 and bottom bridge 5
By installing the two out of phase, collision between the two can be prevented.

In the embodiments shown in FIGS. 6 to 10, a front fender is attached to the bottom bridge. Note that the same reference numerals are used for the same parts as in the previous embodiment.

A front fender 11 is fixed to the lower part of the bottom bridge 5 with bolts inserted through fender mounting holes 12. On both outer sides of the front fender 11, there are protrusions located on the front outer side of the vehicle with respect to the axis 3a of the inner pipe 3 so as to surround approximately 3/4 of the outer circumference of the boot 6 that is covered with the inner pipe 3. It has an arc-shaped insertion part 13 extending from 13a to a protrusion 13b also located rearward with respect to the axis 3a,
The insertion portion 13 has a surrounding wall 14 extending downward along the boot 6, thereby preventing movement and vibration of the boot 6.

A stabilizer mounting seat 7 is provided at the rear of the outer pipe 4. This mounting seat 7 is also arranged radially inward from the outer periphery of the front wheel 1. The stabilizer 9 is attached to the mounting seats 7, 7 from behind with bolts 1.
It is fixed at 0.10. In this case, the bolts 10, 10 are arranged in the same direction as the axis of the outer pipe 4.

The stabilizer 9 can be formed from a rectangular hollow material, a pipe material, a solid material, etc., but it is possible to form a hollow part 15 with an open rear end as shown in FIG. 5, or a hollow part 16 with an open bottom end as shown in FIG. When molded with a substantially U-shaped cross section, the rigidity per weight is improved, and a smooth surface can be placed on the front surface.
It looks better from the front of the vehicle.

In the present invention, since the stabilizer is attached to the front or rear part of the outer pipe as described above, a desired rigidity can be easily obtained by changing the width in the front and back direction, and the stabilizer is fixed from the front and back with bolts, so the installation work is easy. Therefore, even if the stabilizer mounting seat is placed inside the outer circumference of the front wheel, interference between the stabilizer and the boot can be prevented.
