Abstract
A friction drive transmission includes a drive pulley having an engaging face, a tip plate that supports the drive pulley and is configured to pivot about a pivot axis that is parallel to an axis of rotation of the engaging face of the drive pulley, and a friction ring that drives an axle. The friction ring may contact the engaging face of the drive pulley and may be moveable relative to the engaging face of the drive pulley to transition between forward rotation and reverse rotation. When the friction ring moves into a reverse rotation position for reverse rotation of the axle, the tip plate may pivot, with the drive pulley, about the pivot axis from a first position into a second position. The first position may be different from the second position.
