  • Patent number: 8617018
    Abstract: A transmission for operating an auxiliary assembly in a drivetrain of a hybrid vehicle, includes a first sun gear rotatable about a main axis on a drive input side of the transmission, a first planet gear in engagement with the first sun gear on the drive input side of the transmission, a second planet gear on a drive output side of the transmission and mounted with the first planet gear on a common shaft, and a second sun gear in engagement with the second planet gear on the drive output side of the transmission, for coupling to the auxiliary assembly. The first planet gear is connected to the shaft by a first freewheel, which generates a rotationally conjoint connection when the first planet gear overruns in a first direction of rotation, and generates a freewheeling connection when the first planet gear overruns in a second, opposite direction of rotation.

  • Publication number: 20120242085
    Abstract: A yaw-drive system for a wind turbine housed in a movable-in-yaw nacelle affixed atop a tower on a roller bearing. A round-look high-flux core material forms the stator of a circular linear yaw motor. The stator is affixed to the tower and is stationary. A plurality of magnets is affixed to the nacelle in proximity with the core material, such that as the stator is excited in quadrature the nacelle rotates on the roller bearings about a yaw pivot.
