Abstract
An apparatus for selection and engagement of selectable gear ratios in a change speed transmission is disclosed. The apparatus comprises a housing, a shaft mounted for relative axial and rotational movement in the housing, a plurality of shift forks, and a plurality of snap rings. Each of the shift forks includes a hub portion having a bore through which the shaft is received. Each of the snap rings is disposed about the shaft and abuts a corresponding shift fork. Each of the snap rings has a tooth which projects radially from the shaft. Each of the hub portions has a groove which is formed to receive a corresponding tooth such that when one of the grooves is not aligned with a corresponding tooth in response to rotation of the shaft, the other grooves are aligned with a corresponding tooth. Thus, only one shift fork is movable at any time.
