  • Patent number: 6830492
    Abstract: A two stage damping system is provided for a trim cylinder mount of a marine drive unit. The mounting bushings comprise inner and outer tubes with an elastomeric material disposed between the inner and outer tubes. The elastomeric material is structured to provide a soft rate of stiffness in response to relatively light loads, such as shifting loads, and a harder rate of stiffness in response to higher loads, such as during high thrust loads or wide open throttle operation of a marine vessel. The two rates of stiffness are provided by the appropriate placement of cavities either within the elastomeric material or between the elastomeric material and the inner or outer tubes. Alternatively, two different types of elastomeric material can be used to provide the two rates of stiffness.

  • Patent number: 6764066
    Abstract: An hydraulic damping mount has an outer sleeve, an inner sleeve for securing thereto a piston of a spring strut (activatable in at least one direction), an elastomeric body and two chambers. The two chambers are interconnected via a gap. The inner sleeve comprises a radially projecting boss separating the two chambers from each other. The connection between the two chambers is configured in accordance with the invention as a gap between the boss and the outer sleeve so that when activated, the fluid flow through the gap is in the direction opposite to the movement of the boss, resulting in a reduction in the stiffness. This simplifies assembly whilst enhancing the stiffness response of the mount. The invention relates furthermore to a mount for supporting a spring strut in making use of such a mount.

  • Patent number: 6561531
    Abstract: A strut mount structure for a vehicle for supporting a strut of a strut-type suspension is disclosed. Since the strut mount structure does not have any protruded portions with respect to a front hood while maintaining equal distance between the strut mount unit and the front hood, it is possible to freely choose the design of the front hood. Furthermore, the strut mount structure with a satisfactory large distance between the strut mount unit and the front hood absorbs impact well when a pedestrian comes into contact with the vehicle on the front hood.

  • Patent number: 6502883
    Abstract: A body mount for a vehicle includes a rebound cushion assembly in which a first cushion portion provides a progressive rate buildup to provide travel rebound control and a second cushion portion prevents an upper cushion of the body mount from hitting against the vehicle frame. A clamp member partially encloses the first and second cushion portions. The portions are preferably inner and outer rings interconnected by a thin membrane that allows independent action. The first portion is an elongated member always in compression that has a minimal impact on the system rate and loaded height and the second ring comes into selective contact with the vehicle frame to prevent the upper cushion from being lifted from the vehicle frame.

  • Publication number: 20020145242
    Abstract: An elastic member interconnecting a bracket fixed to a vehicle body and a bracket fixed to a damper rod protruding from a damper case is formed into a tubular shape to surround an outer periphery of an upper portion of the bracket. A first liquid chamber defined in part by the elastic member and a second liquid chamber defined in part by a diaphragm communicate with each other through a communication passage. The elastic member is shear-deformed vertically with the vertical movement of the damper rod. Thus, it is possible to reduce the vertical dimension of a damper mount, while ensuring a large amount of change in the volume of the first liquid chamber, as compared with a conventional damper mount in which the block-shaped elastic member provided at the upper portion of the damper case is deformed under compression or tension, to thereby change the volume of the first liquid chamber.

  • Patent number: 6427814
    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.
