Abstract
A gear-shifting device is disclosed. The device comprises a first motor having a first rotor. The first rotor turns clockwise and counter-clockwise, creating a wobbling action. The device further comprises a compound planetary transmission, comprising a transmission ring attached to a ring gear. The compound planetary transmission receives power from the first rotor. The device further comprises a second motor having a second rotor. The second rotor turns clockwise and counter-clockwise. The device further comprises a shift assembly, comprising a drum, a cap, and a pinion gear. The pinion gear receives power from the second rotor. The drum locks with the pinion gear such that the drum rotates with the pinion gear. The transmission ring is attached to the drum, such that the transmission ring moves laterally as the drum rotates. The ring gear locks and unlocks with the cap as the drum rotates. The wobbling action enables the locking.
