Patent number: 5310137Abstract: An active noise control (ANC) system for a helicopter that is operative to effectively nullify one or more high frequency vibrations emanating from the main transmission gearbox thereof at the gearbox/airframe interface, thereby significantly reducing the interior noise levels of the helicopter, that is design optimized to minimize the number of actuators required, and that is design optimized to minimize contamination forces arising from operation of the system actuators. The ANC system includes modified transmission beams that are mechanically stiffened to function as rigid bodies with respect to the one or more of the high frequency vibrations, a plurality of actuators disposed in combination with the modified transmission beams, a plurality of sensors disposed in combination with the modified transmission beams in a collinear, spaced apart functional correlation with respective actuators, and controllers interconnecting individual actuators with respective functionally correlated sensors.Type: GrantFiled: April 16, 1992Date of Patent: May 10, 1994Assignee: United Technologies CorporationInventors: Charles A. Yoerkie, Jr., William A. Welsh, Thomas W. Sheehy

Patent number: 5309789Abstract: An automobile powertrain has at least an engine placed in an engine room and oriented so that its crankshaft is directed transversely, and a transmission placed in the engine room behind the engine. The transmission has input and output shafts arranged coaxially with each other and directed parallel to the crankshaft of the engine. An engine clutch is directly connected to the crankshaft, and a power transfer arrangement is disposed oppositely to the engine with respect to the engine clutch and operationally couples the engine clutch to the input shaft so as to transmit engine output to the transmission. The transmission, engine clutch and power transfer arrangement are independently accommodated in separate chambers of a single unit powertrain case. The transmission chamber and the power transfer chamber are connected to each other by an oil passage through which the input shaft extends from the transmission to the power transfer.Type: GrantFiled: March 25, 1992Date of Patent: May 10, 1994Assignee: Mazda Motor CorporationInventors: Osamu Kameda, Hitoshi Akutagawa, Junichi Okita, Ichiro Hirose

Patent number: 5305848Abstract: An automotive powertrain has an engine placed within an engine compartment and oriented so that its crankshaft is directed transversely. The powertrain also has an automatic transmission placed in the engine compartment behind the engine, and a torque converter operationally coupled to the crankshaft and input shaft of the transmission. Input and are output shafts of the transmission are arranged coaxially with each other and are directed parallel to the crankshaft of the engine. A hydraulic control valve body, through which controlled hydraulic pressure is applied to the transmission so as to shift the transmission, is placed in a space defined below a horizontal plane including a top end of the transmission and behind a vertical plane including an axis of rotation of the crankshaft.Type: GrantFiled: July 31, 1992Date of Patent: April 26, 1994Assignee: Mazda Motor CorporationInventors: Hitoshi Akutagawa, Junichi Okita, Osamu Kameda, Sakumi Hasetoh, Yoshimichi Tanaka

Patent number: 5299880Abstract: An engine coupler and adapter for installing an automobile engine into a vehicle in which a rear mounted engine was originally installed. The coupler comprises a body which is an elongated hollow cylinder, a mounting flange at one end of the cylinder for mounting the coupling device to the flywheel of a transaxle, and a mounting flange mounted at the opposing end of the cylinder shaft for mounting the coupler to an automobile engine crankshaft gear. The flanges, each of which is positioned at a right angle to the cylinder axis, consist of cylindrical disks. Each of the flanges contain properly positioned and shaped apertures to enable the flanges to be attached to the transaxle flywheel and the automobile engine crankshaft gear respectively. Threading is provided interior of the hollow cylinder for threadable connection of the coupler to a transaxle gland nut. An adapter is provided to connect differently-configured flywheel housing components.Type: GrantFiled: October 13, 1992Date of Patent: April 5, 1994Inventor: Daurent J. Bouchard

Patent number: 5295413Abstract: A transmission casing embodying the concepts of the present invention has a one-piece body portion with front and rear faces. The first of two major openings penetrates the front face, and the second of the two major openings penetrates the rear face. A pair of axially spaced front and rear drive gear bearing supports are provided in the transmission casing, and the drive gear bearing supports are axially accessible through the first major opening. A pair of axially spaced front and rear idler gear bearing supports are laterally displaced from the respective drive gear bearing supports and the idler gear bearing supports are also axially accessible through the first opening. A final drive bearing retainer is demountably secured within the second major opening. A final drive rear bearing support is carried by the final drive bearing retainer. An aperture for receiving the final drive front bearing support penetrates the first face and is aligned with the final drive rear bearing support.Type: GrantFiled: October 14, 1992Date of Patent: March 22, 1994Assignee: General Motors CorporationInventor: James F.
