Abstract

Automobile suspension apparatus which also acts as a variable stabilizer. Since a typical conventional stabilizer mainly makes use of the resilient force derived from torsion bars, the body of a vehicle employing such a stabilizer can be tilted by centrifugal force or side winds, and therefore lacks stability during high-speed running. In other words, the stabilizer acts so as to make riding comfort and running stability contradictory conditions. In order to improve both riding comfort and running stability, the function of a laterally mutual and longitudinally linked suspension apparatus is utilized so that instead of torsion bars two pairs of vibration absorber are used, each of these pairs being constituted by vibration absorbers which are combined so as to expand and contract in the same direction in an interlocked relationship by an interaction using the movement of a liquid, and are installed in the longitudinal and lateral directions as automobile suspension springs. Thus the invention provides a laterally mutual and longitudinally linked suspension apparatus which also acts as a variable stabilizer in which the vehicle height and the degree of anti-rolling of the vehicle body can be adjusted by utilizing either or both of the functions of a laterally mutual and longitudinally linked two-wheel interlocking independent suspension and a four-wheel independent suspension, by changing the interaction due to variations in the fluid pressure.

The same applies to a high-speed left turn.The reverse operation is the same. The device has the effect of preventing rolling and pitching because of the change in vertical movement, and the effect of maintaining high-speed running stability because the vehicle body is kept horizontal. Also, if the air volume of each variable auxiliary air cylinder chamber (9) of each fluid suspension unit is increased evenly, the vehicle height will be higher than M, and the left and right alternate front and rear two-wheeled Interlocked independent suspension function is weakened with increasing air, and the four-wheel independent suspension function is strong and the body's roll rigidity is weak, enabling flexible and soft running on rough roads. I do. Furthermore, if the air volume of each variable auxiliary air cylinder chamber (9) is set appropriately and evenly so as to absorb a slight impact from the road surface, the left-right alternating front-rear two-wheels can be formed by the interaction. Interlocking independent suspension function and four-wheel independent suspension function are combined, so that the body has a small port and the suspension can be selected for better riding comfort. The viscous liquid (22) also serves to prevent leakage and protect the piston and cylinder, and the piston ring for sealing ("2S") is used for the piston rod.
