Title: Gas cooled traction drive inverter

Abstract

The present invention provides a modular circuit card configuration for distributing heat among a plurality of circuit cards. Each circuit card includes a housing adapted to dissipate heat in response to gas flow over the housing. In one aspect, a gas-cooled inverter includes a plurality of inverter circuit cards, and a plurality of circuit card housings, each of which encloses one of the plurality of inverter cards.

  • A transaxle driveline for a wheeled vehicle has a high speed turbine engine and a torque splitting gearset that includes a traction drive unit and a torque converter on a common axis transversely arranged with respect to the longitudinal centerline of the vehicle. The drive wheels of the vehicle are mounted on a shaft parallel to the turbine shaft and carry a final drive gearset for driving the axle shafts. A second embodiment of the final drive gearing produces an overdrive ratio between the output of the first gearset and the axle shafts. A continuously variable range of speed ratiosmore » is produced by varying the position of the drive rollers of the traction unit. After starting the vehicle from rest, the transmission is set for operation in the high speed range by engaging a first lockup clutch that joins the torque converter impeller to the turbine for operation as a hydraulic coupling.« less
  • A combined energency switch-off and control rod drive for a control rod of a gas-cooled nuclear reactor includes an electrical notor coupled through a clutch to a cable winch on which is wound a cable connected to the control rod for lowering the rod into the reactor core. One brake of the eddy current type is provided for controlled braking of the cable and a locking brake is provided for purposes of emergency. This locking brake is actuated in accordance with the response of a cable monitoring device whlch is arranged to detect both a relief of the cable asmore » well as an overload.
