Suspension systems are provided where the lower control arm is allowed to separate from the engine cradle at prescribed conditions to deliver the proper wheel kinematics for select cases while maintaining structural integrity for all other load cases. A system includes a vehicle body structure, a wheel assembly, and a suspension system linking the wheel assembly to the engine cradle. The suspension system includes a link coupled with the engine cradle through a first joint and coupled with the wheel assembly through a second joint. The first joint is configured to release the link from the engine cradle under loads above a threshold force and above a threshold angle of the threshold force at the second joint, to provide the desired kinematics.

A vibration-damping device body (10) is provided that includes a first mounting member (11) mounted on one of a vibration-generating portion and a vibration-receiving portion via a bracket (2), a second mounting member (12) mounted on the other of the vibration-generating portion and the vibration-receiving portion, and an elastic body (13) connecting the first mounting member (11) and the second mounting member (12). The first mounting member (11) is fitted into a fitting hole (2a) formed in the bracket (2). A first guide portion (30) is formed on an outer circumferential surface of the first mounting member (11). A second guide portion (20 is formed on an inner circumferential surface of the fitting hole (2a). The first guide portion (30) is fitted into the second guide portion (2f). The first mounting member (11) is formed of a synthetic resin material, and a metal fitting (40) having first engagement surfaces (42a) coming into contact with the second guide portion (2f) is arranged on the first guide portios (30).

An anti-vibration device is provided with: an anti-vibration device body, in which an insulator is disposed between a first attachment member and a second attachment member; and a bracket, which has opposing wall portions and to which the anti-vibration device body is fixed by press-fitting via the second attachment member between the wall portions. The second attachment member is provided with interlocking portions that interlock with the wall portions and restrain the anti-vibration device body from moving in the direction opposite the press-fitting direction when the anti-vibration device body is press-fitted to the bracket. Each of the interlocking portions is configured so as to have an arm part extending in the direction opposite the press-fitting direction, and a hook part provided to the extension-direction end of the arm part and caused to interlock with a to-be-interlocked part of one of the wall portions.

A variable stiffness vibration damping device includes a first support member, a second support member, a main elastic member, a diaphragm, a partition elastic member, a first communication passage, a coil, a yoke, and a magnetic fluid. The first communication passage is provided in one of the first support member and the second support member such that a first liquid chamber and a second liquid chamber communicate with each other via the first communication passage. The first communication passage includes a first circumferential passage. The coil is wound coaxially with the one of the first support member and the second support member. The yoke is included in the one of the first support member and the second support member and forms a first magnetic gap overlapping at least partially with the first circumferential passage.

Aspects of the disclosure relate to an engine support system and method. The engine support system includes a frame mounted engine support and at least one engine mounted coupler. The engine support includes a frame mount with a telescoping body and opposing arms to releasably engage a frame of a vehicle, and at least one jack assembly. Each jack assembly includes a collar coupled to and horizontally movable along the telescoping body, and a jack rod coupled to and vertically movable relative to the collar. The jack rod includes a ball mount configured to insert into the coupler at an underside of an engine block of the vehicle. Each jack assembly is configured to support and/or lift the engine block relative to the vehicle frame by vertical movement of the ball mount into the coupler and relative to the frame mount engaged with the vehicle frame.

A front cover (7) is made of a resin material such as a synthetic resin and is attached to an internal combustion engine body so as to cover the front surface of the internal combustion engine body. The front cover (7) is formed with a mounting part (21) made of a resin material and protruding to the forward side of an internal combustion engine. The mounting part (21) is formed in an elongated hollow shape along the cylinder axial direction of the internal combustion engine. The mounting part (21) is equipped with a vehicle body attachment part (23) for attaching the internal combustion engine to a vehicle body. The vehicle body attachment part (23) is formed integrally with the mounting part (21). It is thereby possible to reduce the weight and number of components of the internal combustion engine.

A fluid-filled vibration damping device includes a switching valve arranged inside the fluid passage passing through a partition member to communicate with a main fluid chamber and a sub fluid chamber and protruding from one wall surface toward the other wall surface of the fluid passage that face each other. A gap is provided between the switching valve and the other wall surface. A tip end part of the switching valve abuts against the other wall surface through a tilt displacement in a swing manner of the switching valve in the passage length direction of the fluid passage to thereby form a switching mechanism for closing the gap. An elastically deformable fin-shaped protrusion protruding from the tip end part of the switching valve toward the other wall surface is provided. A leak passage is formed between a protruding tip end of the fin-shaped protrusion and the other wall surface.

A bracket with an excellent reinforcing effect is provided. A bracket (1) with an opening (A) includes a body (10) and a reinforcement portion (20). The body (10) is made of resin. The body (10) includes a pair of column portions (11) and a pair of connecting portions (12, 13). The body (10) includes a plate portion (15) on at least one of the column portions (11). The plate portion (15) is provided with ribs (16 to 18) that extend from the side of the opening (A) to the bracket outer peripheral side and protrude in the opening penetration direction. The reinforcement portion (20) includes a reinforcement portion (21). The reinforcement portion (21) forms an outer peripheral face (f1) of the bracket (1). The reinforcement portion (21) is arranged so as to overlap the ribs (16 to 18) when viewed in the opening penetration direction.
