Mark O. Bodie - Dayton OH, US

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F16F 9/53

US Classification:

1882672, 26714014

Abstract:

A hydraulic mount is provided having a body with first and second fluid chambers and a decoupler subassembly interposed between to partially define the first and second fluid chambers. The decoupler subassembly comprises first and second flexible decoupler members operatively sealed together to form a third fluid chamber. The first and second chambers may be substantially filled with a magneto-rheological fluid. The third chamber may be filled with a standard hydraulic fluid, like glycol.

International Classification:

F16D 65/12

US Classification:

188218XL

Abstract:

A brake rotor assembly for a dual brake disc braking system includes an annular ring having a plurality of teeth. The teeth are disposed radially about a central axis of the annular ring, and extend inward toward the central axis. The teeth are for slideably engaging a hub (wheel end) having a plurality of channels. The annular ring includes a plurality of pins extending outwardly from the annular ring. A friction disc is disposed radially about the annular ring, and is in interlocking engagement with the plurality of pins. The annular ring and the plurality of teeth are integrally cast from a high strength corrosion resistant material having a tensile strength greater than 260 megapascals to resist fracture during high stress braking conditions and high thermal loads. The friction disc is cast around the annular ring from a grey cast iron.
