  • Synchronizing device
    Patent number: 9518619
    Abstract: The invention relates to a synchronizing device with a synchronizer body, a sliding sleeve, a gearwheel with coupling toothing and a synchronizer ring which is displaceable between synchronizer body and coupling toothing axially in and counter to the synchronization direction(s). With the specification of being able to position the synchronizer ring reliably in a neutral position, it is proposed that the synchronizer ring is fixed to the synchronizer body in the neutral position by means of a spring device.

  • Synchronous speed disconnect of a generator for a hybrid electric vehicle
    Patent number: 9260000
    Abstract: A drive system includes first and second power sources, a planetary gearset including an output, and first and second inputs driveably connected, respectively, to the first and second power sources, a pinion supported for rotation, and a synchronizer for alternately releasing a drive connection between the pinion and output and substantially synchronizing a speed of the pinion and a speed of the output before driveably connecting the pinion and the output.
