Patent number: 7963190Abstract: A gear set for a transmission for use in limited space and capable of transmitting relatively large amounts of power with a small diameter of the gear sets, comprising a series of helical gear elements having stub shafts extending laterally from either side thereof, each of the stub shafts having teeth formed at the remote ends thereof and a central axial bore extending through each gear element and a coupler adapted to engage the teeth on adjacent gear elements join gear elements in driving contact. The gear set having a relatively large effective diameter, and a tension rail extending through the axial bore in the gear elements with retainers at either end of the tension rail so as to effectively permit limited axial movement along the tension rail while preventing inadvertent disengagement.Type: GrantFiled: September 15, 2008Date of Patent: June 21, 2011Assignee: Harrier Technologies, Inc.Inventors: Michael Sullivan, Richard Mizon, John Desilvia, Burke Smith, Timothy Breen, Brian Ide

Patent number: 7922615Abstract: A transfer case is provided with a range unit, an interaxle differential, a clutch assembly and a power-operated actuation mechanism. The range unit includes a planetary gearset driven by an input shaft, and a synchronized dog clutch assembly for releasably coupling one of the input shaft or an output component of the planetary gearset to an input member of the interaxle differential. The interaxle differential further includes a first output member driving a first output shaft, a second output member operably driving a second output shaft. The clutch assembly is a multi-plate friction clutch operably disposed between the first and second output shafts. The power-operated actuation mechanism includes a range actuator assembly, a clutch actuator assembly and a motor assembly operable to control coordinated actuation of the range actuator assembly and the clutch actuator assembly.Type: GrantFiled: May 29, 2009Date of Patent: April 12, 2011Assignee: MAGNA Powertrain USA, Inc.Inventors: Richard Mizon, James S.

Patent number: 7895913Abstract: A power transmission device for a motor vehicle includes a clutch for transferring torque between first and second shafts. A clutch actuation system includes a drive member and a cam member in cooperation with one another. The drive member is driven by an electric motor and includes first and second rollers rotatably mounted thereon. The cam member includes first and second circumferentially extending channels, each having a continually reducing radius. The first and second channels are separate from and overlap one another. The first roller is positioned within the first channel to engage the drive member and the cam member. The second roller is positioned within the second channel to engage the drive member and the cam member such that relative rotation between the drive member and the cam member translates the cam member along an axis of relative rotation to vary the force applied to the clutch.Type: GrantFiled: January 25, 2010Date of Patent: March 1, 2011Assignee: MAGNA Powertrain USA, Inc.Inventors: Richard Mizon, John D.

Patent number: 7813857Abstract: A transfer case for a motor vehicle having an input shaft, a first output shaft, a second output shaft, a clutch, a transfer mechanism, a sensor portion and a magnetoelastic torque sensor. The clutch has a clutch pack and a thrust mechanism that is configured to exert an engagement force on the clutch pack. The clutch pack has a first portion, which is rotatably driven by either or both of the input shaft and the first output shaft, and a second portion that is supported for rotation relative to the first portion. The transfer mechanism couples the second portion of the clutch pack to the second output shaft. The sensor portion is coupled to the first or second output shaft and is at least partially formed of a magnetoelastic material. The magnetoelastic torque sensor is disposed about and radially in-line with the sensor portion.Type: GrantFiled: December 4, 2008Date of Patent: October 12, 2010Assignee: MAGNA Powertrain USA, Inc.Inventors: Richard Mizon, Malcolm E.
