An anti-vibration device including first and second rigid strength members interconnected by an elastomer body, the first strength member includes a base and at least three branches extending from the base along a first direction toward the second strength member, the three branches including two external branches and one central branch. The second strength member includes a transversal portion and at least two branches extending along the first direction from the transversal portion, respectively between the external branches and the central branch of the first strength member. The elastomer body extends transversally to the first direction between the external branches of the first strength member and has four legs extending respectively between the branches of the first strength member and the branches of the second strength member.

Anti-vibration device

Truck fairings are connected together with a vibration-isolating bracket device. The device includes three parts: two brackets and a strap. The brackets are a lightweight material such as aluminum. The brackets are formed and configured to be coupled together by the strap without the need for further fasteners such as bolts or rivets. The strap is flexible and elastic and provides vibration isolation as well as coupling.

Vibration isolator device for vehicle fairings

An anti-vibration assembly is disclosed including a rigid bracket fixed to a vehicle powertrain, a vehicle body and an anti-vibration mount including: a first tubular mounting member, in which the bracket is received; a second mounting member fixed to vehicle body; an elastomer body connecting the first mounting member to the second mounting member; and a rigid strap including two legs and a top. The second mounting member is fitted in the two legs of the strap in the first direction upwards and is pressed by said two legs directly on the vehicle body in said first direction. The strap further includes a bridge portion joining the two legs under the bracket.

Movement limiting anti-vibration assembly

An antivibration apparatus for limiting vibrations of a virbrating element, comprising a mass, two elastic members connected to the mass, and a support member including a metal sheet plate having a central portion and two lateral wings, the lateral wings being fixed respectively to the elastic members and converging slantwise toward the central portion, away from the mass, and the central portion being adapted to be fixed to the vibrating element.

Antivibration apparatus including a mass damper

A hydraulic antivibration support including a first rigid connection device having a base and a vertical pin, a second rigid connection device having a rigid vertical tube, a first elastomer body connecting the base to the second connection device and able to support a permanent weight, a second elastomer body fitted inside the tube. The second elastomer body has two deformable walls, on both sides of a free passage traversed by the pin, defining two hydraulic chambers connected together by a throttled channel.

Hydraulic antivibration support

An anti-vibration sleeve comprising inner and outer strength members, an elastomer body connecting the strength members together and forming two hydraulic chambers, and a C-shaped intermediate member which is snap-fitted around the elastomer body and clamped between the elastomer body and the outer strength member, the intermediate member forming a throttled passage which connects the two hydraulic chambers together.
