Description

【発明の詳細な説明】 本発明はベルト駆動式自動二輪車に関する。[Detailed description of the invention] The present invention relates to a belt-driven motorcycle.

自動二輪車では、スイングアームを車体に支持するピボ

In a motorcycle, a pivot shaft that supports the swing arm on the vehicle body extends across the width of the vehicle body between the driving sprocket of the engine and the driven sprocket of the rear wheel.

Incidentally, in addition to chains, belts have recently been adopted as a driving winding medium for motorcycles.

Conventionally used chains are generally made into a ring by connecting both ends of a non-circular chain with connecting links, but belts are originally manufactured as parts having a ring shape. Therefore, in belt-driven motorcycles, if the swing arm is attached, the swing arm will be unstable.
The shaft gets in the way, making it impossible to attach and detach the endless belt, and when attaching and detaching the belt, it is necessary to disassemble and assemble the suspension device (=l), resulting in poor workability.The problem with such belts is the belt drive. This is the reason why a rear wheel suspension system that solves the above-mentioned problem is long-awaited, but such a rear wheel suspension system has not yet appeared.

Incidentally, it has been proposed that a chain-driven motorcycle be equipped with a rear wheel suspension device as disclosed in Japanese Patent Application Laid-Open No. 147833/1983.

This suspension system uses a chain, and maintains a constant distance between the centers of the engine's drive sprocket and the rear wheel's driven sprocket to prevent the chain from sagging and prevent the chain from coming off. It is intended to prevent this, and is composed of four-bar links.

The rear wheel suspension system includes an upper swing arm (5) and a lower swing arm (6) that are arranged apart from the toothed belt (4) above and below, as shown in FIGS. 2 to 4.
The link member (8) is attached to the axle (7) of the rear wheel (2) and connects the upper swing arm (5) and the lower swing arm (6). Upper swing arm (
5) and the lower swing arm (6) are relatively short in length and extend from a position far behind the drive sprocket (1) to a position above and below the axle (7) of the rear wheel (2). The upper swing arm (5) is provided in a pair on the left and right, is supported by a pivot shaft (9) to a gusset (11) welded to the vehicle body (A), and extends rearward l\, and is a bar (12) that receives the brake reaction force. through the rear wheel (2〉 axle (
7). The lower swing arm (6) branches into two so as to sandwich the rear wheel (2) from both sides and swings backwards.
It extends and is supported via a pivot shaft (10) by a bracket (13) welded to the vehicle body (A).The rear part of the lower swing arm (6) and the front part of the upper swing arm (5) The traversal buffer (14) is installed in a state where it is tilted significantly forward.

The mounting structure of this shock absorber (14) creates a wide space between the upper swing arm (5) and the rear side of the vehicle body (A) above it, ensuring the amount of upward movement of the rear wheel (2). The cushion stroke can be made longer, and the seat height can be lowered by keeping the cushion stroke the same as before.In addition, the large forward tilt angle of the shock absorber (14) allows non-linear shock absorption. It is something that you can get characteristics from.
