Abstract
Fluidless mounts capable of damping motion in several directions are disclosed. The mounts utilize hysterisis losses in an elastomeric material to absorb energy. The losses are induced by rigid rib and grooved elements which are displaced along the surface of an elastomeric layer in pressure engagement therewith. Amplitude-sensitive damping embodiments are disclosed.
Claims19
A mount for damping motion in at least two directions, comprising:
- a first member adapted to be connected to a first object,
- a second member adapted to be connected to a second object,
- a resilient element interposed between the members and mounting the first member for translation in a first direction alongside and relative to the second member and for motion in a second direction lateral to said first direction,
- means providing a first resiliently deformable layer extending along said first direction,
- means providing a second resiliently deformable layer extending along said second direction, and
- means providing a rigid rib engaging both said first and said second resilient layers for slidably deforming said layers in response to motion of said first member relative to said second member in either or both of said directions,
- whereby relative motion between the members can be damped in one or more directions.

A mount for damping motion in at least two directions comprising:
- a first member adapted to be connected to a first object,
- a second member surrounding said first member and adapted to be connected to a second object,
- a resilient elastomeric element interposed between the members and mounting the first member centrally of the second member for motion in a first axial direction relative to the second member and for motion in a second trans-axial direction lateral to said first direction,
- means including said resilient element providing a first resiliently deformable elastomeric layer surrounding said first member,
- means providing a pair of second resiliently deformable elastomeric layers extending outwardly from said first member and movable therewith in both said axial and trans-axial directions,
- a rigid ribbed element movable with said first member and engaging both said first and said second pair of resilient layers for slidably deforming said layers in response to motion of said first member relative to said second member in either or both of said directions,
- whereby relative motion between the members is damped by the interaction of the ribbed element with the elastomeric layers.

A mount for damping motion in at least two directions, comprising:
- a first member adapted to be connected to a first object,
- a second member surrounding said first member and adapted to be connected to a second object,
- a resilient elastomeric element interposed between the members and mounting the first member for motion in a first axial direction centrally of the second member and for motion in a second direction trans-axial of said first direction, said elastomeric element having a cavity surrounding said first member and providing a first resiliently deformable layer extending along said first direction,
- a pair of flanges carried in axially spaced relation by said first member in said cavity, each of said flanges having an elastomeric layer thereon disposed with said layers in confronting relation,
- a ribbed element engaging both said first and said second pair of resilient layers for slidably deforming said layers in response to motion of said first member relative to said second member in either or both of said directions, and
- means mounted on said first member for clamping said ribbed element between said pair of layers.
