Abstract
A forkless synchronizer arrangement selectively couples one or more gears to a drive shaft that is rotatable about a rotation axis. A shift collar, rotated by the drive shaft, is configured to disengage from a first of the gears when in a first neutral axial position and to engage the first gear when in a first engaged axial position to transmit rotational input from the drive shaft to the first gear. A rail is arranged in parallel with the rotation axis. A rail arm has an end fixedly coupled to the rail and another end coupled to the shift collar to permit relative rotation and to transmit axial shifting movement to the rail in response to axial movement of the shift collar between the first engaged and neutral axial positions. A sensor proximate the rail senses an axial position of the rail.
