少する。Next, to explain the operation of this device, as shown in Figure 2,
By turning the steering wheel 9 to the left, the oil pressure in the left oil chamber e of the power cylinder 6 of the power steering increases, and the oil pressure in the right oil chamber f increases.
oil pressure drops. Accordingly, the oil pressure of the hydraulic cylinder devices B and D connected to the oil chamber e by the hydraulic pipe 24 increases, and the oil pressure of the hydraulic cylinder devices ft, G, and A decreases. As a result, the rear wheel 13 turns to the left. i.e. rear wheel 1
If the force exerted by the hydraulic pressure is larger than the side force F acting on the rear wheel 13, the rear wheel 13 turns to the left, and the side force F acts on the rear wheel 13.
Compared to this, when the acting force due to hydraulic pressure is small, the amount of right-hand cutting that normally occurs is reduced. When the handlebar 9 turns to the right, the rear wheel 18 turns to the right or reduces the amount of turning to the left in the same manner as described above.
以上述べたようにサイドフォースＦにより生じる後輪の
切れ込み量が減少し高速走行時の安定化を計ることがで
きる。As described above, the amount of cut in the rear wheels caused by the side force F is reduced, making it possible to stabilize the vehicle during high-speed driving.

という問題点があった。However, in such a suspension bushing deflection control device, it is necessary to provide a hydraulic cylinder device separately from the bushing in order to control the deflection of the suspension bushing, resulting in a complicated structure. In addition to being heavy and expensive, there was a problem in that vibrations from the road surface, which were transmitted through the cylinder to the vehicle body, were not sufficiently blocked.

ある。This invention was made by focusing on these problems, and instead of providing the hydraulic cylinder device separately from the bushing, a pair of oil chambers that function in the same way as the hydraulic cylinder device are installed inside the rubber of the suspension bushing. The purpose of this invention is to solve the above-mentioned problems by providing the following.
以下、この発明を図面に基づいて説明する。The present invention will be explained below based on the drawings.
第８図は、この発明の一実施例を示す図である。FIG. 8 is a diagram showing an embodiment of the present invention.
まず構成を説明すると、２６はブツシュの中心に位置す

と連通ずる配管接続具８０を接着する。In this embodiment, concave portions are formed in the center of the outer peripheral surfaces of both opposing sides of a rubber cylindrical bushing 27 to form an oil chamber 28, and a semi-cylindrical cover plate 29 that closes this oil chamber 28 is used as the bushing. The oil chambers 28 are attached to the cover plates 29 on both sides by baking and adhering them to the outer peripheral surfaces of the oil chambers 28.
A piping connector 80 that communicates with is glued.

を行うことができる。B, O, and D are not necessary, and the hydraulic pipes 24 and 25 can be connected directly to each piping connector 80.Next, the operation will be explained. In FIG. 8, when the oil pressure in the left oil chamber 28 is increased and the oil pressure in the right oil chamber 28 is decreased, the bushing 27 deforms as shown in FIG. 4. This effect is the same in the case of the bushing shown in FIG. Therefore, the bushing 27 of the present invention is applied to the insulator rubber of the rear wheel suspension member 14 of the vehicle as shown in FIG. By arranging the system in the same manner as shown in FIG. 1 and using the hydraulic pressure of the power cylinder 6 of the power steering as the hydraulic power source, the same functions as those of the apparatus shown in FIGS. 1 and 2 can be achieved.
