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).

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.

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 drive system for an electric vehicle includes a housing having a first housing portion, a second housing portion connected to the first housing portion, and a third housing portion connected to the second housing portion. The third housing portion includes a torque arm connectable to a vehicle chassis. A hypoid gear set is mounted in the first housing portion, and an electric motor is mounted in the third housing portion.

Proposed is a transmission mount for a vehicle in which the structure of an upper insert and a lower insert integrated with a single bridge among components of the transmission mount is improved to reduce the static stiffness in the right-left direction (i.e., the Y direction) of the transmission mount. The strength of the transmission mount in the front-rear direction (i.e., the X direction) and the static stiffness in the top-bottom direction (i.e., the Z direction) is reinforced so that the pitching motion and the vertical bounce behavior of the transmission may be efficiently controlled. Accordingly, booming noise caused by the rolling motion of the transmission is minimized, thereby improving NVH performance and meeting driving performance.

A hydraulically damping mount for mounting a motor vehicle unit on a motor vehicle body includes a support and a support mount which are interconnected by a support spring made of an elastomeric material. In embodiments, a support spring limits a working chamber which is separated from a compensating chamber by a separating device, wherein the working chamber and the compensating chamber may be filled with a fluid and may be connected to one another via a damping channel included in the separating device, wherein the separating device may include two nozzle discs between which a first membrane and a second membrane are arranged, and wherein one of the membranes has at least one through-hole.

A transmission mount of a rear wheel drive vehicle may increase both vibrational noise performance and collision performance of the vehicle.

Methods and systems are provided for using energy harvesting modules as a means for providing energy to power an electrical load and/or as a means for monitoring an operational state of a component or components to which the energy harvesting module is coupled. In one example, a method includes, via a controller, monitoring an actual amount of energy generated by an energy harvesting module attached to a mounting structure that is used to secure a torque-supplying machine to a frame, comparing the actual amount to an expected amount, and indicating degradation of the mounting structure and/or the torque-supplying machine based on the comparing. In this way, the energy harvesting modules may both power electrical loads and simultaneously serve as a monitor for component degradation.

A fluid-filled vibration damping device including: primary and auxiliary liquid chambers; a partition provided between the two chambers; and a movable plate supported movably in a plate thickness direction thereof by the partition. The movable plate receives liquid pressure of the two chambers on its opposite faces so as to constitute a liquid pressure absorber. The partition includes at least one communication hole opening onto its surface facing the movable plate. The movable plate includes at least one elastic protrusion projecting toward the communication hole. The elastic protrusion includes a peripheral wall to be pressed in compression and shear directions and be elastically deformed to a radially inner side of the communication hole as well by coming into contact with a wall portion of the communication hole due to movement of the movable plate in the plate thickness direction.
