Title: Vibration resistant device
Inventor: KATO HIROAKI
IPC: G03F7/20
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a vibration resistant base or to control the pressure so that the deforming state is not transited, by extracting a component which deforms only the vibration resistant base without relating to the attitude control and the vibration damping control from the air spring pressure. SOLUTION: A pressure target value output device 8 outputs the pressure target values of the air springs 2a-2d to keep a vibration resistant base 7 in a target attitude. The signals of the pressure sensors 4a-4d are respectively subtracted from the pressure target values to determine the difference signals. The difference signals include a deforming component for deforming the vibration resistant base 7. A deforming component extracting device 9 outputs the deforming component pressure on the basis of the result of the calculation for subtracting the singals of the pressure sensors 4a-4d from the pressure target values. A proper compensator 10 is acted on the pressure, whereby a deforming component pressure distribution unit 11 controls the pressure of the air springs 2a-2d through the power amplifiers 12a-12d and the air valves 3a-3d to make the deforming component pressure zero.  Whereby the attitude control, the vibration damping control and the pressure control can be simultaneously executed.

Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To improve comfortableness to ride in of a vehicle by forming a hole of a car body bracket long in the horizontal direction. SOLUTION: A hole 7 long in the car body almost horizontal direction (the arrow E direction) is formed in a car body bracket 6. In the hole 7, the car body almost horizontal direction and the right-angled direction (the arrow F direction) are formed shorter than usual. In bushes 4 and 5, a shape is changed according to the hole 7 of the car body bracket 6. That is, in the bushes 4 and 5, a car body horizontal directional part is turned in boring or a liquid packed. Therefore, a spring constant of the car body horizontal directional part of the bushes 4 and 4 is reduced. Initial longitudinal displacement of a tire can be absorbed by the bushes 4 and 5 having a low spring constant.  Therefore, flexibility of the tire to a recess-projection of a road surface is improved, and since a initial longitudinal directional movement of the tire can be softened, comfortableness to ride in is improved.
