ABSTRACT:
In an hydraulic active vehicle suspension system using a linear hydraulic cylinder as a primary actuator, controlled hydraulic pressure is supplied to an upper chamber of the hydraulic cylinder defined by a smaller pressure receiving surface of the piston and the cylinder while a reduced and fixed pressure is supplied to a lower chamber of the hydraulic cylinder defined by a larger pressure receiving surface of the piston and the cylinder, and an accumulator is connected to the lower chamber so that a desired hydraulic actuation can be accomplished by the controlled hydraulic pressure while sudden forces or inputs containing high frequency components applied to the lower chamber are absorbed by the accumulator. Thus, the accumulator offers a favorable response to the wheel riding over a bump or otherwise experiencing sudden movements and the absence of any accumulator connected to the upper chamber ensures a high speed response property of the system without requiring a large power capacity of the pump serving as the pressure source for the system.
