Abstract: A liquid-encapsulated damper mount includes an outer member fixed to a vehicle body, and an inner member fixed to an upper end of a damper. The outer member and the inner member are connected to each other by first, second and third elastomer members. A first liquid chamber defined between the first and second elastomer members communicates with a second liquid chamber defined between the second and third elastomer members through a restriction. The restriction is defined in mating surfaces of the inner member and a ring member which are made of a metal and hence, even if the second elastomer member is deformed in any manner, the cross-sectional area of the restriction is not changed. Thus, when a load of a very low speed is inputted from a road surface, a stable damping force can be generated in the liquid-encapsulated damper mount, thereby preventing the resonance of an unsprung portion to enhance the riding comfort during traveling of a vehicle on a flat road.

Abstract: The coil spring of a vehicle shock absorber can be seated on an elastomeric sound isolator pad whose spring engagement surface has plural slot-like depressions evenly spaced around the pad circumference. These slot-like depressions form raised ribs that provide the contact surfaces for the lowermost convolution of the coil spring. Each rib can readily deform under the spring force. Side surfaces of the ribs can act as heat-dissipating surfaces. The slot construction allows the pad to be formed out of a reasonably high durometer and highly wear-resistant elastomer without adversely affecting the desired rib deflection.

Abstract: An outer sleeve and an inner sleeve are connected to each other by an elastomeric member. Main liquid chambers and subsidiary liquid chambers, circumferentially connected to the main liquid chambers, are defined between the elastomeric member and the outer sleeve and communicate with each other through orifices. When a large load is input in directions X and X', the volume of the main liquid chambers are decreased, thereby causing the liquid forced out of the main liquid chambers to flow through the orifices, so that a damping force is produced by a resistance, due to a liquid, generated during flowing of the liquid. When a load in directions Z and Z' is input by a load in the directions X and X', the volume of the subsidiary liquid chambers adjoining the main liquid chambers is decreased, thereby causing the liquid, forced out of the subsidiary liquid chambers, to flow through the orifices, thus producing a damping force.

Such an increase in the stiffness of the substrate actuator detunes from resonance structures supporting a device from which vibratory energy emanates, and also inhibits transmission of vibratory energy of specific frequencies into structures supporting equipment sensitive to vibrations.
