The front mount comprises: a core configured to be connected to the power train to receive vibration transmitted from the power train; an outer pipe disposed outside the core and spaced from the core by a predetermined distance with respect to a radial direction of the core; an elastic body disposed between the core and the outer pipe to absorb vibration transmitted thereto from the core; and a stopper disposed on an outer surface of the core to be spaced from an inner surface of the outer pipe by a predetermined distance.

A fluid-sealed engine mount may include an insulator integrally formed on an external side of a mount core configured to be coupled to an engine and having a chamber with which fluid for insulation of vibration is sealed; an orifice module mounted below the mount core to divide the chamber into two chambers and having a fluid passage for flow of the fluid; an air chamber provided at a center portion of the orifice module and filled with air; and an elastic membrane mounted above the air chamber at the center portion of the orifice module to seal the air chamber airtightly.

A motor-vehicle engine suspension elastic device has a main body of metal and/or composite material elongated in a direction parallel to the longitudinal direction of the motor-vehicle. The elastic device has a first end that can be connected to a structural connecting element of a motor-vehicle, and a second end that can be connected to a motor-vehicle engine. The main metal body of the elastic device includes at least one portion elastically deformable in the aforesaid longitudinal direction.

A torque rod including: a rod member; and a rubber bushing provided at a lengthwise end of the rod member, wherein the rubber bushing includes an inner axial member, an outer tubular member, and a rubber elastic body connecting the inner axial member and the outer tubular member with each other, the lengthwise end of the rod member is fixed to the inner axial member of the rubber bushing constituted by a part separate from the rod member, and a stopper to limit a relative displacement amount of the inner axial member and the outer tubular member in the rubber bushing is constituted in contact sections of the rod member and the outer tubular member.

A mount for supporting a power train in the vehicle, may include a stopper assembly combined on an internal surface of a housing to be disposed in an annular shape along vicinity of outsides of insulators combined with the housing, wherein the stopper assembly may include: an external ring combined on the internal surface of the housing; and a plurality of stopper members fixed on an internal surface of the external ring to be positioned along the vicinity of the outsides of the insulators, each of the a plurality of stopper members being spaced from each other to be in contact with an internal insulator of the insulators.

A hydraulic engine mount may include a nozzle plate including upper and lower nozzle plates, wherein each of the upper and lower nozzle plates may include a rim having an annular shape and forming a peripheral portion of the nozzle plate, a hub disposed at a central portion of the nozzle plate, and ribs connecting the rim and the hub while close contacting and supporting the membrane, and wherein the contact area between each rib of the upper nozzle plate and the membrane differs from the contact area between each rib of the lower nozzle plate and the membrane.

A rubber stopper configured to be mounted onto a stopper part of a vibration damping device having a mounting hole, including: a stopper main body to be overlapped on the stopper part; and at least one mounting leg projecting from the stopper main body to be inserted into the mounting hole of the stopper part. The mounting leg includes a neck to be positioned within the mounting hole, a protrusion to pass through the mounting hole and be positioned on a back surface side of the stopper part, and a detent positioned between the neck and the protrusion to be detained with the back surface of the stopper part. The detent includes at least one notched part where an outside diameter of the detent is made small, the notched part being provided partially in a circumferential direction of the detent.

A fluid-filled tubular vibration-damping device including: an inner shaft member and an outer tube member connected by a main rubber elastic body defining a non-compressible fluid filling region partitioned into two axially-opposite fluid chambers connected by an orifice passage, by a partition wall rubber fixed to a side of the inner shaft member in an inner periphery thereof and inserted in a side of the outer tube member at an outer periphery thereof so that the partition wall rubber is axially movable relative to the side of the outer tube member; a seal tubular part formed integrally at the outer periphery of the partition wall rubber to axially protrude to opposite sides; and a thicker annular fitting part formed integrally at each protruding tip of the seal tubular part, and fitted in the side of the outer tube member, slidably along it.

An engine mounting structure includes an engine mount fixed to a frame of a vehicle body and an engine bracket fixed to an engine. The engine mount includes a mount fixture on which the engine bracket is assembled. When mounting the engine, the mount fixture and the engine bracket engage with each other at a first engagement portion close to the engine and a second engagement portion close to the frame. In the first mounting portion, the mount fixture urges the engine bracket toward the engine for engagement, and in the second engagement portion, the mount fixture urges the engine bracket toward the frame for engagement.
