Publication number: 20070144843Abstract: An MR-fluid (magnetorheological-fluid) hydraulic mount includes a hydraulic-mount partition plate assembly and an electric coil. The partition plate assembly has a longitudinal axis, has first and second sides, and has an MR-fluid through orifice extending substantially parallel to the longitudinal axis from the first side to the second side. The partition plate assembly is devoid of any non-MR-hydraulic-fluid orifice. The electric coil is substantially coaxially aligned with the longitudinal axis and is adapted to magnetically influence the MR-fluid through orifice. The MR-fluid through orifice is positioned radially outward of the electric coil.Type: ApplicationFiled: December 27, 2005Publication date: June 28, 2007Inventors: Mark Bodie, Mark Long

Publication number: 20050230890Abstract: A magnetorheological-fluid hydraulic mount includes a hydraulic-mount partition plate assembly, a hydraulic-mount decoupler, an electric coil, and a flexible membrane assembly. The partition plate assembly has first and second sides, has a non-magnetorheological-fluid first orifice, and has a magnetorheological-fluid second orifice. The first orifice has a first terminus positioned at the first side and a second terminus positioned at the second side. The second orifice has a first end positioned at the first side and has a second end positioned at the second side. The hydraulic-mount decoupler is operatively connected to the first orifice. The electric coil is disposed to magnetically influence the second orifice.Type: ApplicationFiled: April 16, 2004Publication date: October 20, 2005Inventors: Sanjiv Tewani, Mark Bodie, Jamieson Kiefer, Mark Long, John Walterbusch

Publication number: 20050173211Abstract: 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.Type: ApplicationFiled: February 10, 2004Publication date: August 11, 2005Inventors: Patrick Hopkins, Mark Long, Mark Bodie

Publication number: 20050035509Abstract: A powertrain mount comprises an orifice plate including two tracks, a control track and an isolation track. The control track is spirally formed within the orifice plate, which has an exit and entrance on either side of the plate. The control track provides damping to control damping from engine bounce; whereas, the isolation track controllably provides dynamic rate dip. The isolation track is formed between an alignment plate and rotatable track member, each having an exit and entrance, respectively. The rotatable track member and the alignment plate are sealingly engaged and affixed to a decoupler and an annular area disposed about the orifice plate of the powertrain mount. The exit of the alignment plate is adjacent the decoupler. The rotatable track member forms a cavity with the molded body of the powertrain mount, with the entrance exposed to fluid within the cavity for controlling and minimizing vibrations within the powertrain.Type: ApplicationFiled: September 14, 2004Publication date: February 17, 2005Inventors: Mark Bodie, Mark Long, Sanjiv Tewani

Publication number: 20050029720Abstract: A hydraulic mount having first and second fluid tracks, and a decoupler finctioning as an air spring with two remotely selectable settings. The settings allow tailoring of the air spring characteristics to provide mount damping for differing engine operating states, such as engine idle. A solenoid is used to select a smaller or larger air volume to control the characteristics of the air spring and, in turn, the dynamic response of the hydraulic mount. An integral controller provides switched operation of the solenoid and compensates for variations in temperature and input voltage, as well as minimizing electrical noise generated by the solenoid when it is energized.Type: ApplicationFiled: August 7, 2003Publication date: February 10, 2005Inventors: Mark Bodie, Mark Long, Sanjiv Tewani, Ronald Beer, Bruce Heaston, Brandon Fedders

Patent number: 6622830Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a casing to form inner fluid volume and outer fluid volume, with first valve and second valve for controlling flow between the inner fluid volume and the outer fluid volume, and an accumulator using closed cell foam as a compressible material for fluid fill variation and thermal expansion. First valve controls flow from the outer fluid volume to the inner fluid volume for one direction of rotation of the rotor, while second valve controls flow from the inner fluid volume to the outer fluid volume for the opposite rotation of the rotor. Thus, the valves are configured to provide independent control of damping for each direction of rotation. A valve holder supporting the valves and providing flow passages is designed for powdered metallurgy fabrication.Type: GrantFiled: March 6, 2001Date of Patent: September 23, 2003Inventors: Michael L. Oliver, William C. Kruckemeyer, Mark Bodie, Ronald G. Smith, Jr., James E. Dingle

Patent number: 6536565Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a case to form fluid volumes, with valves for flow control and an accumulator for fluid fill variation and thermal expansion mounted internal to the rotor. A first check valve and first control valve mounted in a first flow passage within the rotor allow flow from second fluid volume to first fluid volume, but restrict flow from the first fluid volume to the second fluid volume. Similarly, a second check valve and a second control valve mounted in a second flow passage within the rotor allow flow from the first fluid volume to the second fluid volume, but restrict flow from the second fluid volume to the first fluid volume. Thus, the valves are configured to provide independent control of damping for each direction of rotation.Type: GrantFiled: March 6, 2001Date of Patent: March 25, 2003Assignee: Delphi Technologies, Inc.Inventors: Michael L. Oliver, William C. Kruckemeyer, Mark Bodie
