The sleeve insert interfaces with the mount housing and is rotatable within the mount opening, the damping assembly is rotatable within the insert opening, and the insert opening is spaced apart from the mount opening.

A viscous torsional vibration damper includes: a) an annular damper housing, which bounds a damper chamber; b) an inertia ring arranged in the damper chamber; c) a bearing device, which supports the inertia ring in the damper housing and which has at least one bearing element with an axial bearing region and/or a radial bearing region, d) a shear gap between the inertia ring and the damper housing, which shear gap is filled with a viscous fluid, e) wherein a plurality of the axial bearing segments and/or a plurality of the radial bearing segments is circumferentially distributed on the at least one bearing element.

A torque transmitting device that can be rotatably mounted about an axis of rotation includes a series damper having a first damper unit, a second damper unit and a coupling unit. The first damper unit has a damper output side and the second damper unit has a damper input side. The coupling unit is arranged between the damper output side of the first damper unit and the damper input side of the second damper unit. The coupling unit has a first coupling part and a second coupling part, wherein the first coupling part and the second coupling part are arranged axially offset in relation to one another. The first coupling part connects the damper output side of the first damper unit to the second coupling part. The second coupling part connects the first coupling part to the damper input side of the second damper unit.

A viscous torsional vibration damper has an annular damper housing defining a damper chamber; an inertia ring in the damper chamber; a bearing device supporting the inertia ring with one or more bearing elements. At least one bearing element is a ring not circumferentially closed in a mounted state. A shear gap between the inertia ring and the damper housing is filled with a viscous fluid. The at least one bearing element that is not circumferentially closed is cut to length from a strip. In order to produce the bearing element, a strip is provided, on which one or more axial bearing sections and one or more radial bearing sections and preferably one or more webs are formed. Then, the bearing element is cut to length from the strip and the bearing element is inserted into an open damper housing and laid on a bearing seat.

A vertical decoupler assembly for a hydraulic mount including a first fluid chamber and a second fluid chamber includes a travel plate defining an interior space for receiving a removable vertical decoupler assembly. The vertical decoupler assembly includes an elastically deformable and tubular shaped diaphragm for dampening small vibrations across the mount. The vertical decoupler assembly may include an inner cage and an outer cage, each including a rigid, perforated, tubular wall disposed on either side of the diaphragm for limiting its radial deflection in each direction. The vertical decoupler assembly may include a rigid lower insert having an inverted cup shape with a second rim sealingly engaging the diaphragm and secured to the inner and outer cages. The decoupler diaphragm also includes a flange and a ring-shaped upper insert for nesting within and sealing against a throat at the upper end of the travel plate.
