A vehicle includes a case member, a stay member and a rib. The case member is supported by a frame of a vehicle body with a mount member being interposed. The stay member is suspended between a boss part of the case member and a member of a case member side in the mount member, a longitudinal direction of the stay member intersecting a longitudinal direction of the frame. The rib extends in the case member in a direction that is an extension of the longitudinal direction of the stay member at a root of the boss part.

An engine mount for a vehicle may include a support bracket including a mounting hole formed in one end portion thereof, an engine-mounting plate provided at an opposite end portion thereof to be connected to an engine, and a coupling portion protruding from an external surface of the one end portion thereof; a fluid-filled assembly including a hook cup configured to be inserted into the mounting hole in the support bracket; and a rubber assembly configured to be mounted to a vehicle body, wherein, in a state in which the fluid-filled assembly is inserted into the mounting hole in the support bracket, the fluid-filled assembly is stacked on a top surface of the rubber assembly, and a housing of the rubber assembly is coupled to the coupling portion of the support bracket.

The invention relates to an anti-vibration support, comprising first, second and third frames, which are metallic, accessible from the outside and separate from one another, at least one part made of elastomer. The invention is characterized in that the support also comprises a member made of thermoplastic material comprising at least one reinforcement, which has continuous-fibers and which is a prefabricated part, to reinforce the mechanical strength of the anti-vibration support, the first and second frames being far from one another in a first, substantially horizontal, direction, are intended to be fixed to a body of a motor vehicle and are connected one to another by means of the member made of thermoplastic material, the member made of thermoplastic material being over-molded with respect to at least a portion of at least one surface of the reinforcement, with respect to first and second surfaces of the first and second frames and with respect to at least one surface of the part made of elastomer supporting the third metal frame intended for the suspension of a vibrating portion of the vehicle, for damping and filtering mechanical vibrations between the body and the vibrating portion.

This vibration-damping device is configured such that an outer mounting member (11), an inner mounting member (12), or a partition member (16) has formed therein: a first restriction passage (23) for providing communication between a fourth liquid chamber (21) and a second liquid chamber (15) or a third liquid chamber (20); and a second restriction passage (24) for providing communication between the second liquid chamber (15) and the third liquid chamber (20). The flow resistance of the first restriction passage (23) and that of the second restriction passage (24) are different.

A tubular vibration damping device has a structure in which an inner shaft member is connected with an outer tube member made of synthetic resin by a body rubber elastic body. The outer tube member has a structure in which a tubular part extends in an axial direction from an inner peripheral end of a flange of an annular plate shape. A press fit rubber is fixed to an outer peripheral surface of the tubular part, and an axial surface of the flange on a side from which the tubular part extends is exposed without being covered with the press fit rubber. A notch penetrating in a radial direction is provided at an axial end of the outer tube member that includes the flange. A connecting rubber that connects the body rubber elastic body and the press fit rubber is provided in the notch.

A fluid-filled engine mounting apparatus may include a core provided with a center into which a center bolt is inserted; an insulator with an internal lower portion in which a first fluid chamber is formed and with an upper internal circumferential surface adhered to an external circumferential surface of the core; an upper housing mounted on an upper portion of the insulator; upper and lower orifice plates mounted on an internal circumferential surface of the insulator and are provided with a center hole; a membrane mounted on the center holes between the upper and lower orifice plates; a first case mounted on a lower external circumferential surface of the insulator; a first diaphragm mounted on a lower portion of the insulator that closes the first fluid chamber; and a longitudinal vibration absorbing device provided at an upper portion of the insulator.

A pair of bracket fastening parts (7, 12, 91, 92, 121, 122, 161, 162) are provided on a side of the main body in an adjoining relationship, each bracket fastening part including a plurality of bosses (32 to 35, 72 to 75, 102 to 106, 132 to 137) arranged in a convex polygonal pattern and a plurality of ribs (37 to 42, 60, 80 to 84, 110 to 115, 140 to 146) connecting the bosses in a prescribed pattern. At least two of the bosses of one of the bracket fastening parts are shared by an adjoining one of the bracket fastening parts. Thereby, the engine can be adapted for multiple applications while minimizing an increase in the weight of the engine.
