A vibration proofing device (10) includes an insulator (50) interposed between a first attaching member (30) and a second attaching member (40), and is disposed in an internal space (95) of a second bracket (90). The first attaching member (30) is formed to have two side walls (33, 33) parallel to each other to face the inner face of the second bracket (90). The second attaching member (40) is a tubular member having an opening (41a) passing therethrough in an upper-lower direction. At least one of side edge portions of each side wall (33) is disposed outside the opening (41a) of the second attaching member (40). Each side wall (33) is provided on an outer face thereof with a stopper (51) made of an elastic material. With this configuration, it is possible to sufficiently absorb an impact shock resulting from the stopper (51) hitting the second bracket (90).

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 including a vibration-damping device main unit attached to a bracket from a lateral side by a second attachment member being fitted to opposed walls provided on widthwise opposite sides of the bracket. The bracket includes flexible latches extending from the respective opposed walls forward in a direction of attachment. The second attachment member includes outer recesses respectively opening onto surfaces overlapped with the respective opposed walls. Each latch has a slope portion sloping inward in a width direction of the bracket such that a distal end face of the latch is inserted in the corresponding outer recess. The distal end face of the latch is latched by a forward wall inner face of the outer recess, and displacement of the second attachment member relative to the bracket in a direction of dislodgment opposite to the direction of attachment is limited.

Provided is an anti-vibration device which is provided between a vibration-side bracket attached to a vibration member and a non-vibration-side bracket attached to a non-vibration member, the anti-vibration device including: a first attachment member attached to the vibration-side bracket; a second attachment member attached to the non-vibration-side bracket; and an insulator provided between the first attachment member and the second attachment member, wherein the first attachment member includes a stopper portion which faces an engagement portion formed on the non-vibration-side bracket, and the insulator includes a cover portion which covers at least a surface of the stopper portion facing the engagement portion.

A control system for an active powertrain mount includes a control signal which is based on the input velocity of the chassis at the active powertrain mount. The control signal may be proportional to the input velocity or to the mount velocity, which is the difference between the input velocity of the chassis at the active powertrain mount and the output velocity of the powertrain component at the active powertrain mount. The input velocity of the chassis at the active powertrain mount may be determined by a controller based on the CG heave and the roll and pitch velocities of the chassis. The output velocity of the powertrain component at the active powertrain mount is determined by the controller by integrating an acceleration signal from a component accelerometer disposed on the powertrain component proximate to the active powertrain mount. Corresponding methods for controlling an active powertrain mount are also provided.

A suspension member includes: a front frame including a front cross member extending in a vehicle width direction; a rear frame at least partially made of light metal and including a rear cross member extending in the vehicle width direction, the rear frame being placed on a vehicle rear side of the front frame and joined to the front frame; and a protective member joined to the rear cross member so as to form a closed section together with the rear cross member.

The invention relates to a vibration damper for connecting two devices to one another, in particular an engine to an environment (100) of the engine, for example a car body, wherein the vibration damper includes a damping section (20) and a fastening section (10), wherein the mounting portion (10) is formed with first and second pipe socket portions (14) having a flange (12), and wherein the damping portion (20) at least partially surrounds the fastening portion (10) at the outer surface thereof.

A fluid-filled vibration damping device including a movable film housed within a housing space of a partition partitioning a pressure receiving chamber and an equilibrium chamber. An outer peripheral end of the movable film includes a contact part and a sealing part being respectively in contact with a pressure receiving chamber-side wall inner surface and an equilibrium chamber-side wall inner surface of the housing space. A communication passage, which communicates with a gap circumferentially between the movable film and the housing space, is provided away from the contact part in the outer peripheral end of the movable film. The outer peripheral end of the movable film will be separated from the equilibrium chamber-side wall inner surface due to a pressure differential arising between the two chambers so as to form a relief passage interconnecting the two chambers including the gap and the communication passage.
