この発明は小型車両の後輪懸架装置に関するもので、簡
単な構造で独立懸架的な良好な乗心地を得られるように
したものである。DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a rear wheel suspension system for a small vehicle, and is capable of providing a good ride comfort of an independent suspension system with a simple structure.
「従来の技術」

構造をとりていた。"Prior Art" Since the engine output of a small vehicle is small, it is necessary to reduce the overall weight of the vehicle. For this reason, the rear wheel suspension system had to have a simple mechanism. Conventionally, the left and right rear wheels were mounted directly on a single frame-shaped swing arm, or the vehicle body and axle housing were mounted on both sides of the vehicle body. The axle housing and the center of the car body were connected to the engine using two links.

空中に浮いた車輪が空転して発進できないことがある。``Problems to be Solved by the Invention'' In the conventional technology as described above, the former frame-shaped swing arm has a problem in that when one wheel rides up on a convex part due to road surface conditions while driving, the other axis does not move. If the drive wheels are driven by an engine with a differential gear,
The wheels floating in the air may spin and make it impossible to start.
一方、後者のアクスルハウジングをエンジンと２本のリ

問題を解決するものである。On the other hand, the latter structure in which the axle housing is connected to the engine with two links requires the axle housing to be strong and provide bending rigidity, and requires two rear suspension vents. However, there were problems in that it had a multi-fiber structure and was expensive. This invention solves these problems.

できる。``Function'' In such a configuration, if the stabilizer is made of spring steel, the frame-shaped swing arm will be able to tilt left and right freely on uneven road surfaces, so that the left and right rear wheels (drive wheels)
Since it is farther away from the road surface and the stabilizer provides the force to restore it to a horizontal position, it is only necessary to provide one rear suspension in the center of the swing arm. This makes it possible to obtain ride comfort close to that of independent suspension with a simple configuration.

It is designed to support Unit 5. Further, a suspension suspension unit 20 is interposed between a bracket 19 provided at the rear center of the swing arm 4 and the rear center of the vehicle body frame 2. Brackets 21 are attached near both ends of the pipe 110, and a stabilizer 23 made of spring steel is attached to the bolt bracket 21 via a rubber pusher 22 with a nut 24. And this stabilizer 25
The middle part is bracket 25 and rubber push! -26, both sides of the middle portion of the swing arm 4 are supported from below.

なシ、横方向の安定性が向上するととＫなる。In this rear wheel suspension system configured as described above, the swing arm 4 is pivotally attached to the vehicle body frame 2 via the mount member 13 with a large degree of freedom of deformation, and the swing arm 4 is mounted from below by the stabilizer 23. With this support, the swing arm 4 can freely tilt in the left-right direction on uneven road surfaces. This tilt angle is obtained by the torsional force of the stabilizer 23 at the part where the stabilizer 23 is in contact with the swing arm 4 (between the two sockets 25 and 25 on both sides). This means that only one Venge adventure unit 201d is required. Since the brackets 21 and 25 of the stabilizer 23 are oblique to the vehicle body, the stabilizer 23 does not serve as a support, and the lateral stability is improved.
