Abstract
An example mount assembly includes a first chamber, at least partially defined by a first elastomeric element and a second chamber, at least partially defined by a second elastomeric element. The assembly also includes an inertia track having a central opening defining an axis. The inertia track defines a serpentine passage in fluid communication with the first chamber and the second chamber. The inertia track is moveable along the axis relative to the first elastomeric element and the second elastomeric element.
Claims24
A hydromount assembly comprising:
- a first chamber and a second chamber;
- an inertia track separating the first chamber and the second chamber, the inertia track having a central opening and including, relative to the central opening, a radially inner surface and a radially outer surface, the inertia track having a passage between the radially inner surface and the radially outer surface that fluidly connects the first chamber and the second chamber, wherein a first elastomeric element is free of contact with a second elastomeric element, and the first elastomeric element and the second elastomeric element are both free of contact with a third elastomeric element;
- an engagement member at least partially disposed in the opening of the inertia track and rigidly coupled to the inertia track to move in unison with the inertia track;
- and
- a shaft extending through the central opening, the shaft including a first shaft section and a second shaft section, the first shaft section and the second shaft section contacting the engagement member.
A hydromount assembly comprising:
- an upper mount having a first elastomeric element;
- a lower mount including an upper portion having a second, different elastomeric element, a central portion having a third, different elastomeric element, and a lower portion having a fourth, different elastomeric element, 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;
- and
- an inertia track having a passage fluidly connected with a first chamber and a second chamber, wherein the upper portion and central portion at least partially define the first chamber and the lower portion and the central portion at least partially define the 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.
A method of installing a hydromount assembly, the method comprising:
- providing an upper mount including a first elastomeric element, and a lower mount including an upper portion including a second elastomeric element, a central portion including a third elastomeric element and an inertia track having a passage that fluidly communicates with a first chamber and a second chamber, and a lower portion including a fourth elastomeric element;
- 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 therethrough, wherein at least one second opening radially outwards of the inertia track extends through the upper portion, central portion, and lower portion along the axis;
- and
- inserting at least one fastener through the at least one second opening to secure the upper portion, the central portion, and the lower portion together.
