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.

A vehicular motor mount made of a motor mount assembly and a frame mount assembly made of four components: a base plate, a capture ring, a post and a bushing. The post mechanically connects directly to the engine mount bracket and the base plate directly connects to the subframe of the vehicle. The polymer bushing is bonded directly to the post. The concave capture ring is directly connected to the base plate forming a capture housing with a cavity wherein the post and bushing of the motor mount assembly are constrained but not directly connected to the base plate or capture ring of the frame mount assembly. With no direct connection between the two assemblies, the engine is not directly connected to the subframe. This improves vehicle's ride. The bushing and the capture ring are common to all vehicular motor mounts. The motor mount may be replaced in pieces rather than in its entirety.

A powertrain torque roll restrictor includes a first bracket having an elongated body defining a first bracket opening at a distal end and a central axis, a second bracket coaxial with and adjacent to the first bracket, and a third bracket coaxial with and adjacent to the second bracket opposite from the first bracket, with the third bracket defining a third bracket opening cooperable with the first bracket opening. The second bracket defines a second bracket opening receiving the elongated body such that the second bracket is positioned about the elongated body. The powertrain torque roll restrictor further includes a first rubber element positioned between the first bracket and the second bracket, and a second rubber element positioned between the second bracket and the third bracket, with the brackets being configured to hold the respective rubber element in compression.

A suspension bushing for a powertrain of an electric vehicle includes amandrel, an outer sleeve and a rubber mainspring connected between the mandrel and the outer sleeve. The rubber main spring includes multiple main parts arranged at intervals and surrounding the outer contour of the mandrel. At least one side of each of the main parts is provided with an extending part. An end surface of the extending part and an end surfaceof each main part form a stepped structure.

In an anti-vibration apparatus having a bracket where an anti-vibration apparatus body in which a first mounting member and the second mounting member are connected by a body rubber elastic body is horizontally mounted to the bracket by fitting parts disposed on two sides of a width direction of the second mounting member in the anti-vibration apparatus body to fitting grooves disposed on opposite inner surfaces on two sides of a width direction of the bracket, a locking hole is provided on a deep wall part located on a deep side in a mounting direction of the second mounting member in the bracket, and a locking part is disposed at a tip portion in the mounting direction of the second mounting member to the bracket, and prevents return in a direction opposite to the mounting direction by inserting and locking the locking part to the locking hole.

A hydraulically damping assembly bearing has two fluid-filled chambers which lie axially opposite each other and are hydraulically connected by a channel. A first chamber forms a working chamber enclosed by a bearing spring body and a second chamber forms a compensating chamber enclosed by a bellows. The compensating chamber has an axially extending inner wall encircling an interior. The bearing includes an annular body axially between the working and compensating chambers, enclosing an axial throughopening opening into the working chamber and closed by a membrane integrally formed with the inner wall of the bellows. The membrane has a central region defined by the inner wall and together with the inner wall delimits the interior. The membrane has a collar region encircling the central region and integrally formed with the central region. The outer circumference of the collar is rigidly connected to the annular body and/or the spring body.

The present disclosure discloses a trunnion mount for mounting an engine, in particular a combustion engine, to a chassis, comprising a support element rigidly connected and/or connectable to the engine having a ring portion with an outer bearing surface, which may be arranged concentrically around the crankshaft; a female support having an inner bearing surface for surrounding the bearing surface of the support element, the female support forming the link between the chassis and the engine; and a rubber bearing arranged between the inner bearing surface of the female support and the outer bearing surface of the support element. In one or more examples, the trunnion mount includes a rubber bearing that is directly vulcanized on at least one of the bearing surfaces and/or wherein the ring portion is formed as a separate element from a mounting portion of the support element and connectable thereto via axial screws.

A fluid-sealed engine mount controls the movement of an engine mounted to a vehicle body and insulates from vibration. In particular, the fluid-sealed engine mount improves vibration damping performance and dynamic characteristics compared to a conventional engine mount, thereby enhancing noise, vibration, and harshness (NVH) performance.
