Abstract
An example mount assembly includes a first chamber and a second chamber. 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.
Claims17
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;
- 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 contacting the engagement member on a first axial side and the second shaft section contacting the engagement member on a second, opposite axial side to sealingly engage the inertia track.
2 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;
- 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;
- and at least one fastener radially outward of the inertia track, the at least one fastener is disposed through at least one opening in each of the lower portion, central portion, upper portion, and upper mount such that the upper mount and lower mount are attached.
