Abstract
An isolator includes multiple lobes that increase the overall volume of the material used to form the isolator. The isolator may be enclosed by several covers used to constrain the isolator and allow for the additional material provided by the lobes. An assembly of the isolator and the covers may be secured to an object (e.g., a drive unit or subframe) using respective openings in the lobes and the covers.
Claims4
An isolator assembly, comprising:
- an isolator, comprising:
- a body that defines a curved surface and a planar surface;
- a first lobe extending from the body and comprising a first lobe opening;
- and
- a second lobe extending from the body and comprising a second lobe opening;
- and
- a first cover comprising first set of extensions that at least partially cover the first lobe, the second lobe, the curved surface, and the planar surface, the first set of extensions comprising:
- a first opening aligned with the first lobe opening, and
- a second opening aligned with the second lobe opening;
- and
- a second cover comprising a second set of extensions that at least partially cover the first lobe, the second lobe, the curved surface, and the planar surface, the second set of extensions comprising:
- a third opening aligned with the first lobe opening, and
- a fourth opening aligned with the second lobe opening;
- and
- a first bushing disposed in the first opening, the first bushing comprising a first shaft and a first flange;
- and
- a second bushing disposed in the first lobe opening, the second bushing comprising a second shaft and a second flange, wherein the first shaft contacts the second shaft, and the first flange and the second flange are configured to compress the first lobe.
