A vibration damping device including a main unit including first and second attachments connected by a rubber body, the second attachment including metallic first and second connectors inserted into metallic first and second grooves of a bracket. The metal is exposed on outer and lower faces of the first connector to be in metal-to-metal contact with groove-inside bottom and lower faces of the first groove. An upper urging rubber on the first connector contacts a groove-inside upper face of the first groove. The metal is exposed on a lower face of the second connector to be in metal-to-metal contact with a groove-inside lower face of the second groove. Upper and outer urging rubbers on the second connector contact groove-inside upper and bottom faces of the second groove. Detent engagers between the connectors and the grooves prevent dislodgment of the connectors from the grooves.

Disclosed is a work vehicle having a load carrier deck provided at a rear portion of a vehicle body to be vertically pivotable between an elevated discharging posture and a lowered load carrying posture. An engine section is provided under the load carrier deck. The engine section includes an engine, an exhaust muffler for the engine, and a muffler heat insulating cover for covering an outer circumference of the exhaust muffler. The muffler heat insulating cover is supported by a vehicle body frame via an anti-vibration member.

A spring element, in particular a jounce bumper, for a vehicle shock absorber contains a longitudinal axis, a base body having a length along the longitudinal axis, and an end portion configured for contact against a damper cap of the vehicle shock absorber. The base body is elastically deformable between an uncompressed basic state and a compressed state in which the base body is at least partially compressed in the direction of the longitudinal axis. The end portion contains a contact surface that is wound along a helix around the longitudinal axis.

A connection assembly for connecting a first element to a second element is provided. The connection assembly has a male element and a female element. The female element has a barrel nut. The barrel nut has a conical inner portion positioned at a first longitudinal region and a cylindrical inner portion positioned at a second longitudinal region. The barrel nut has a first engaging element portion and a first plain portion arranged alternatingly around a circumferential direction of the barrel nut. The male element has a cylindrical bolt-like shape and has a second engaging element portion and a second plain portion arranged alternatingly around a circumferential direction of the male element. The male element further has flattened sides at the second plain portion. The second engaging element portion of the male element is configured to engage with a respective one of the first engaging element portion of the barrel nut.

A micro-engine including a rotation structure, the rotation structure including a head portion, a rear portion, and a deformable portion connecting both portions. The deformable portion is deformable in elongation or compression along a main axis and includes a spring element displaying a free end. The free end of the spring element includes at least an abutment member. The deformable portion further includes a wheel-platform which displays a first and a second face, being configured to cooperate with the free end of the spring element in order to transform a back-and-forth movement of the at least one spring element into a rotational movement of the wheel-platform.

The present disclosure provides a rotational spring dampener including a core having an opening therethrough, a first solid component having a first set of bosses, a second solid component having a second set of bosses, and a tensile member positioned between the first solid component and the second solid component. The tensile member is composed of a solid silicon polymer.

An energy transmission control mount comprises a carrier having a first major surface, an opposite second major surface and an aperture provided therein. Channels are provided adjacent opposite ends of the first surface. Vibration dampening material is provided on the carrier. The vibration dampening material substantially lines the channels and the aperture and extends over at least a portion of the second surface.

An isolation coupler for coupling a functional element to a support structure includes a first bracket. The first bracket includes a number of first-bracket sides. The number of first-bracket sides forms a closed polygonal shape, in plan view. The isolation coupler further includes a number of isolators coupled to each one of the first-bracket sides. The isolation coupler also includes a second bracket. The second bracket includes a number of second-bracket sides. The second bracket sides are coupled to the isolators. The number of second-bracket sides is equal to the number of first-bracket sides and forms the closed polygonal shape, in plan view. The isolators separate each one of the first-bracket sides from a corresponding one of the second-bracket sides to attenuate a load transferred from the first bracket to the second bracket.

An acoustical isolating device used to minimize or eliminate noise or vibrations between the walls/ceilings and building structures is contemplated. The contemplated device includes a specially designed/configured steel spring with unique structural elements, cylindrical grommets, and a washer releasably affixed to one of the grommets.
