摘要： A vibration-damping device capable of reducing the transmission of noise caused by a water pump of a hybrid vehicle, for example, to a vehicle compartment. The vibration-damping device includes a cushion member, a pump mounting member, and an elastic support member. The cushion member supports the pump, and includes holding portions each with a slit formed between an upper and lower surface thereof for insertion therein of end edges of a pump extension member that extends from the pump. The pump mounting member includes inverted L-shaped cross-section retaining portions provided on an upper surface thereof, the supporting portions being disposed between the retaining portions and the upper surface of the pump mounting member to retain the cushion member to the pump mounting member. The elastic support member engages a lower side of the pump to provide support against lateral deflection of the pump.

摘要： A vibration insulating mount is provided having a flanged body. A rubber body covers flanges provided at both ends of the flanged body, thereby defining a lower support and an upper support. A stopping section of an upper case is provided which has a clearance hole. The hole is the same plan shape as the upper support and is slightly larger than the supper support. The mount is constructed so that when the upper case is fixed to the rubber body, postures of the clearance hole and the upper support are conformed. The mount is further constructed so that the upper support may passed through the clearance hole and the upper case 37 can be rotated and fixed to the rubber body 31. Thus, the upper case is prevented from interfering with the upper support, so that the stopping section is disposed between the supports and opposed thereto so as to touch any one of the supports, upon elastic deformation of the rubber body. A method of assembling an insulating mount is also provided.

摘要： A vibration control device including a bracket, and a vibration control body. The bracket has a stay portion for connection to an engine, a flange portion formed at one end of the stay portion, and a stabilizer portion to damp large magnitude movements of the body. The vibration control body includes an insulator made of anti-vibration rubber or other resilient material, an upper plate, and a stopper portion. The flange portion preferably slidably receives the upper plate in order to couple the bracket and vibration control body together.

摘要： A fluid-filled vibration isolator includes a hollow, thick-walled, rubber body which opens downwardly, an annular side plate which has an upper part bonded to an outer surface of the rubber body, a bottom plate sealed to a lower end edge of the cylindrical side plate by caulking, a partition, and a rubber diaphragm. Peripheral edges of the partition and the diaphragm are both strongly sandwiched by the lower end edge to define a main fluid chamber between the rubber body and the partition and an auxiliary fluid chamber between the partition and the rubber diaphragm. A lower part of the side plate inclines obliquely and outwardly toward the lower end edges. A peripheral part of the partition bends into an L-shaped cross-section and contacts the obliquely and outwardly inclining lower part to define an annular space having a closed triangular cross-section. The annular space is blocked circumferentially by a projecting wall formed in the partition. The annular space opens into the main fluid chamber through a recess formed in the partition adjacent to the projecting wall and opens into the auxiliary fluid chamber through a through hole formed in the partition on the side of the projecting wall opposite to the recess to define a throttle passage interconnecting the main fluid chamber and the auxiliary fluid chamber.
