Hydraulic cylinder devices A, B, C, and D are installed between the suspension member 14 and the vehicle body 1 so as to rotate around fixing pins 19 of 8.
and the left oil chamber e of the power cylinder 6 of the power steering for the front wheels and the hydraulic cylinder devices B and D.
are connected by a hydraulic pipe 24, and the right oil chamber f of the power cylinder 6 and the hydraulic cylinder devices A and C are connected by a hydraulic pipe 25.

時は、上述したと同様にして後輪１３は右に切れ
るか、左切れ量を減少する。 Next, to explain the operation of this device, as shown in FIG. 2, when the steering wheel 9 is turned 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 decreases. 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 C and A decreases. As a result, the rear wheel 13 turns to the left. In other words, when the force exerted by the hydraulic pressure is greater 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.
If the force exerted by the hydraulic pressure is small compared to the above, the amount of rightward turning that would normally occur will be reduced. When the steering wheel 9 is turned to the right, the rear wheels 13 are turned to the right or the amount of turning to the left is reduced in the same manner as described above.
以上述べたようにサイドフオース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.

があつた。 However, in the case of 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, which results in a complicated structure and a high weight. In addition to being expensive, there was a problem in that vibrations from the road surface, which were transmitted to the vehicle body through the cylinder, were insufficiently damped.

することを目的とするものである。 This invention was made by focusing on these problems, and instead of providing a hydraulic cylinder device separately from the bushing, a pair of oil chambers that have the same function as the hydraulic cylinder device are installed in the rubber of the suspension bushing. The purpose of the present invention is to solve the above-mentioned problems by providing it inside.
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.

A concave portion is formed in the center of the outer circumferential surfaces of both opposing sides of the bush 2 to form an oil chamber 28, and a semi-cylindrical cover plate 29 that closes the oil chamber 28 is provided as a semi-cylindrical cover plate 29 for closing the oil chamber 28.
7, and the piping connectors 30 communicating with the oil chamber 28 are bonded to the cover plates 29 on both sides thereof, respectively.

作用を行うことができる。 Next, the effect will be explained. In FIG. 3, 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 bush 27 deforms as shown in FIG. 4. This effect is the same in the case of the bush shown in FIG. Therefore, this invention bushing 27 is designated as No. 6.
As shown in the figure, it is applied to the insulator rubber of the rear wheel suspension member 14 of the vehicle, and
8 is arranged in the same direction as the operating direction of the hydraulic cylinder device shown in FIGS. 1 and 2, and the hydraulic pressure of the power cylinder 6 of the power steering is used as the hydraulic pressure source, the device shown in FIGS. A similar effect can be performed.

断が良好になるという効果が得られる。 As explained above, according to this invention,
Since the oil chamber corresponding to the oil chamber of the hydraulic cylinder according to JP-A No. 57-99470 is provided in the rubber bushing, the hydraulic cylinder device that was provided separately from the bushing is no longer required, reducing weight and cost, and simplifying the structure. In addition, since there is no need for a hydraulic cylinder device that easily transmits vibrations, it is possible to obtain the effect that vibrations and isolation from the road surface are improved.
また第５図の実施例に示したブツシユは上記の
