Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear wheel suspension system for a motorcycle, and in particular to an improvement in which a rear shock absorber is located at the center of the vehicle body.

The rear wheel suspension system of a motorcycle has a
A book glue absorber is installed, and this 7t (il-
Some have a structure in which the intermediate portion is pivotally attached to the main body frame or connected to the rear swing arm via a cushion lever. In this type of motorcycle, the rear shock absorber occupies a large part of the rear shock absorber at the center of the unit, so the air cleaner installed around this area cannot have a large volume, and there are also restrictions on the layout of the battery and electrical components. There was a problem with the

The present invention has been developed in view of this point.

For this reason, the invention of wJl of the present invention supports the front part of the rear cushion lever holder at the rear swing arm pivot point of the single frame and the two-sided cross section of the upper part thereof, and Inside the cushion lever
131 Part 1 and 2 are shown, and a rear shock absorber 7 is installed between the front end of the rear cushion lever and the front part of the rear swing arm, and between the rear end of the rear cushion lever and the front part of the rear swing arm. The middle part is connected to the rear cushion lever rod.

Also, in the second invention, in addition to the first invention, a battery holder is installed on the upper part of the rear cushion lever via a bridge plate? f: Installation, and furthermore, an air cleaner, electrical components, etc. are mounted around the battery loaded on the pantry holder.

Hereinafter, six examples of the practicality of the first invention will be explained with reference to FIG. car body 7 frames 1
A plate-shaped first bracket 2 is integrally attached to the rear swing arm 3, and the fJ'fJ end of the rear swing arm 3 is pivotally connected to a shaft (not shown). An axle (not shown) is suspended from the rear end of the rear swing arm 3 to support a rear wheel.

r on the part above the bracket 2 of the single frame 1,
A rearwardly facing second bracket 4 is provided, and the front upper and lower ends of the cushion lever holder 5 are attached to the first and second brackets 2.4. ing. Note that the rear cushion lever holder 5 is attached to the first bracket 2 side so that it is tightened together with the front end of the rear swing arm 3. As a result, the front portion of the rear cushion lever holder 5 is supported at two locations: the pivot point of the rear swing arm 3 of the vehicle body frame l, and the upper portion vc. “At the rear of the rear cushion lever holder 5, the middle part of the rear cushion lever 6 is [fill!].

The front end of this rear cushion lever 60 is inserted between the front end of the rear swing arm 3 and the rear cushion lever 60.
The rear end of the rear cushion lever 60 and the intermediate portion of the rear swing arm 3 are connected by a rear cushion lever rod 8. To connect the rear shock absorber 7 and rear cushion lever rod 8 to the rear swing arm 3, attach a bracket 9 to the rear swing arm 3. Install JO'C. These brackets 9,
Brackets 9 of the rear swing arm 3 are attached to the front end of the rear swing arm 3 so as to be aligned downwardly, and the bracket 10 is attached to the intermediate portion of the rear swing arm 3 so as to be aligned downwardly.

In the first invention described in the embodiments above, the rear cushion lever holder 5r is supported on the single frame l at the pivot point of the rear swing arm 3 and the 2' point of the upper part thereof, and The rear shock absorber 8 is attached by a bracket 9 attached near the front end facing toward the
By receiving the lower end of the rear shock absorber, a space is created between the parts that was conventionally occupied by the upper part of the rear shock absorber. Therefore, in the second invention, this part is utilized. For this reason, the second invention, in addition to the first invention, attaches a battery holder to the upper part of the rear cushion lever holder via a bridge plate, and further includes an air cleaner around the battery loaded on the battery holder. It is configured to be equipped with electrical components, etc.

Next, an example of the second invention is shown in FIGS. 1, 2, and 3.
Referring to the figure, reference numeral 11 is a bridge grate, which is formed by bending a printing plate into a U-shape. Both ends of this bridge plate 110 are attached to the rear cushion lever holder 5t7)i portion by the same l1tl (not shown) that pivotally attaches the middle portion of the rear cushion lever 6. A box-shaped battery holder 12 is attached to the top of this bridge grate 11 with screws (not shown). 7L of batteries 13 are loaded on the pantry holder 12 (see FIG. 3). Around this battery 13, an air cleaner 14 and a product 15 are installed.
etc. will be installed.

As described above, the present invention provides a two-meter motor vehicle in which the rear shock absorber is located at the center of the vehicle body, and the rear shock absorber and the rear This means that the legs of the mechanism that connects to the swing arm can be placed at a lower position than conventional ones. Therefore, since Munehiro is generated above it, the capacity of the air cleaner and battery attached to this part can be made large. In addition, it is possible to assemble the parts surrounding the rear cushion and attach them all at once to the ctLfML body frame, which improves work efficiency during manufacturing. Furthermore, there are M benefits in terms of inspection services and costs.
