この発明は、自動二輪車のパワーユニット懸架装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power unit suspension system for a motorcycle.
小型の自動二輪車では、エンジンと伝動装置を一体的に
作ったパワーユニットを設け、パワーユ □ニットの後

によってパワーユニットが揺動して後輪がクッシヨンで
きるようにしている。エンジンは運転によって揺動を発
生するので、フレームに振動が伝わることを減衰させる
ため、軸着部に弾性ブツシュ等を介在させて浮動的に軸

ニットの取付は部分は、剛性尚く丈夫なものに補強する
ので、製造コストが高くつく。Small motorcycles are equipped with a power unit that integrates the engine and transmission, and the rear wheel is rotatably attached to the rear of the power unit. = −, L #1Ii7
'+L/T+111rto -! In the ry' unit type, the front end of the power unit is pivotally attached to the lower part of the frame, and a rotating unit is connected between the rear of the power unit and the rear of the frame, and the rotating unit swings the power unit to rotate the rear wheel. It is designed to be cushioned. Since the engine generates vibrations during operation, in order to dampen the transmission of vibrations to the frame, the engine is floatingly attached to the shaft with an elastic bushing or the like interposed in the shaft attachment portion. Therefore, the number of parts is large, and the manufacturing cost is high. In addition, the cushion rugs are thickened on the side away from the rear part, which moves away from the center of gravity and exerts a force that twists the rear wheel while driving, which is unfavorable in terms of stability. In addition, the manufacturing cost is high because the parts to which the shoelace unit is attached must be reinforced to be rigid and strong.
この発明は、かかる問題を解決して、安価にできるよう
に改善したもので、以下本発明を図面に示す実施例につ
いて説明する。The present invention has been improved to solve these problems and to be inexpensive.Examples of the present invention shown in the drawings will be described below.

パワーユニットｌの前端を、弾性片ｔを介し、押え金具
りで、バネ帯板ｊに連結する。The power unit/ is a combination of the engine part λ and the transmission gear M@b part 3, so the power supply μ is rotatably attached to the rear part. The front part of the nonone strip j is fastened to the lower part of the frame base with bolts, with the wide side facing up and down in the front-rear direction. . The rear end of the spring band □ plate j is pivoted to the lower part of the power unit l by a horizontal shaft 7. and,
The front end of the power unit l is connected to the spring strip j via the elastic piece t with a presser metal fitting.
作用について説明する。The effect will be explained.
バネ帯板ｊは、路面のシラツクを受けたとき、上下方向

が’ｉ！性片にを介して連結しであるので、弾性片ざＫ
よって振動を減衰でき、バネ置板ｊ自体でも減衰できて
、フレーム基に伝わる振動を少くできる。The spring strip j bends in the vertical direction when subjected to bumps on the road surface, so that the rear wheel can move up and down to provide cushioning. The spring strip I has high rigidity in the lateral direction, and can be arranged along the center line of the frame 6 and the rear wheel ψ, and is located on the center of gravity, so that it can resist the force that causes the rear wheel 1 to twist in the lateral direction. There is no additional impact, and driving safety is good. The vibration of the engine part is caused by the rear end of the nonone strip j being pivotally supported by the horizontal shaft 7, and the front side of it being 'i! Since it is connected to the elastic piece through the elastic piece K
Therefore, vibrations can be damped, and the spring mounting plate j itself can also dampen the vibrations, thereby reducing the vibrations transmitted to the frame base.

トの下側で、目立つこともなくて体裁がよい。As explained above, in this BA, the front part of the spring band plate with the wide side facing up and down is fastened to the lower part of the frame, and the rear end of the spring band plate is attached to the rear wheel so that it can rotate freely. The horizontal shaft is attached to the lower surface of the power unit, and the lower front end of the power unit is attached to the spring band plate via an elastic piece, so the spring band plate can be placed on the center of gravity, and twisting force is reduced. It is possible to improve running stability without adding any additional force. In addition, the vibrations of the engine can be damped by the elastic pieces and the tapered strips, and the transmission of vibrations to the frame can be reduced. Moreover, it has a simple structure, can be produced at low cost, and has good productivity. Also, the nonone strip is on the underside of the frame and power unit, so it doesn't stand out and looks good.
