ABSTRACT:
Spring-assisted shift apparatus includes a plate rotatable about an axis to a plurality of positions, the plate defining a cam track. A cam follower is operatively associated with the cam track, and is adapted to move a shift fork in response to selective rotation of the plate. A spring-assist mechanism includes an assist cam track defined by the plate so as to have an arcuate first track surface with a center of curvature on the axis, and a second track surface oriented such that a line perpendicular thereto does not intersect the axis. A spring member supports an assist cam follower in operative association with the assist cam track such that the assist cam follower is in contact with the first track surface when the plate is in one position, and is in contact with the second track surface when the plate is in another position. The spring member is stressed so as to apply a preload biasing force on the plate.
