Abstract: A planetary damper is disclosed that includes a planetary gear set and at least one clock spring. The planetary gear set includes multiple rotatable gear components including a sun gear, a planet gear assembly having a plurality of pinion gears rotatably mounted on a planet carrier, and a ring gear. The at least one clock spring includes an elongated substrate wound circumferentially around the planetary gear set. The clock spring has an innermost radial rung and an outermost radial rung spaced radially outwardly from the innermost radial rung. Each of the innermost radial rung and the outermost radial rung is connected to a different one of the gear components of the planetary gear set such that the clock spring damps vibrations imparted to the planetary damper. The use of the planetary damper within torque converter assembly to damp torsional vibrations is also disclosed.

Abstract: A powertrain coupling includes a flexplate configured to be connected to an engine output, a torque converter configured to be connected to a transmission input, and at least one friction clutch disposed between the flexplate and the torque converter and configured for actuation by movement of the torque converter. A powertrain one-way clutch includes engagement elements movably coupled between input and output elements, and at least one friction clutch carried between the input and output elements. A torque converter includes a rear cover, a front cover coupled to the rear cover, and including a frontward facing clutch surface, and a one-way clutch integrated into the front cover and including a one-way clutch plate integrated into the frontward facing clutch surface of the front cover.

Abstract: A cam based infinitely variable transmission incorporation a ratcheting drive mechanism with one set of planetary gears and a cam with two followers mounted on a carrier with said gears and adapted to in infinitely variable in output but maintain a uniform output for a given uniform input. The followers are can be shifted in relation to the three dimensional cam by a shifter and clutches are used to handle the relative motion of the gears and follower shafts.
