Abstract
An apparatus for selection and engagement of selectable gear ratios in a change speed transmission is disclosed. The apparatus comprises a shaft mounted in a housing, a plurality of shift forks, and a shift plate. Each of the shift forks is axially movable along the shaft. Each of the shift forks also has a projection extending therefrom. The shift plate has a plurality of first patterns therethrough. Each first pattern includes axial and transverse pathways arranged to receive a corresponding projection such that when one of the projections is not aligned in an axial pathway of one of the first patterns in response to lateral movement of a shifting actuator, the other projections are aligned in axial pathways similarly located in the other first patterns. Subsequent axial movement of the shifting actuator imparts movement to only one shift fork to engage the desired gear.
