Abstract
An example mount assembly includes an upper mount and a lower mount. The assembly also includes an inertia track having a central opening defining an axis. The inertia track defines a passage in fluid communication with the first chamber and the second chamber. The inertia track is moveable along the axis.
Claims18
A hydromnount assembly comprising:
- an upper mount disposed about an axis, the upper mount comprising an insert, a ring radially inward of the insert, a tube radially inward of the ring, and a first elastomeric element at least partially radially disposed between the insert and the ring, wherein the first elastomeric element includes at least one opening extending circumferentially about the axis and disposed between the ring and the insert, wherein the upper mount provides a first damping rats in a first radial direction different than a second damping rate in a second radial direction, wherein the first damping rate is less than the second damping rate and the first radial direction aligns with a portion of the at least one opening;
- a lower mount including an upper portion, a central portion, and a lower portion, the lower mount including a shaft, wherein the central portion includes an engagement member;
- and
- an inertia track having a passage fluidly connected with a first chamber and a second chamber, wherein the inertia track separates the first chamber and the second chamber, the inertia track having a first central opening about the axis, wherein the shaft extends through the first central opening, wherein the engagement member is disposed in the inertia track.

A method of installing a hydromount assembly, the method comprising:
- providing an upper mount including an insert, a ring radially inward of the insert, a tube radially inward of the ring, and a first elastomeric element, and a lower mount including an upper portion, a central portion including an inertia track having a passage that fluidly communicates with a first chamber and a second chamber, and a lower portion;
- aligning the upper portion, central portion, and lower portion, wherein the upper portion and central portion define the first chamber and the lower portion and the central portion defines the second chamber, wherein the first chamber and the second chamber are separated by the inertia track having a first central opening about an axis dimensioned to receive a shaft there through;
- aligning the insert, the ring, and the tube concentrically such that the ring is radially inward of the insert and the tube is radially inward of the ring;
- aligning a second opening in the first elastomeric element to be offset from at least one protrusions extending from the ring
- disposing the first elastomeric element in a radial direction at least partially between the insert and the ring;
- inserting the tube into an opening in the first elastomeric element;
- and
- attaching the upper mount to the lower mount.
5 more elements
A hydromount assembly comprising:
- an upper mount having a first elastomeric element;
- a lower mount including an upper portion, a central portion, and a lower portion, the lower mount including a shaft, wherein the upper portion includes a first shaft section, the lower portion includes a second shaft section, and the central portion includes an engagement member, wherein the first shaft section is integral with the upper portion and the second shaft section is integral with the lower portion, wherein the first shaft extends into both the central portion of the lower mount and into an opening of the upper mount, wherein the first shaft section abuts the engagement member on a first side and the second shat section abuts the engagement member on a second side such that the first shaft section and the second shaft section are on opposing sides of the engagement member, and
- an inertia track having a passage fluidly connected with a first chamber and a second chamber, wherein the inertia track separates the first chamber and the second chamber, the inertia track having a first central opening about an axis, wherein the shaft extends through the first central opening, wherein the engagement member is disposed in the inertia track between the first shaft section and the second shaft section.
