ABSTRACT:
A shifting mechanism (10) for a change gear transmission is provided. The shifting mechanism includes a plurality of axially shiftable shift rails (16, 18, 20 and 22) each of which carry shift forks (24, 26, 28 and 30) for axial movement therewith. Each of the shift rails is provided with a shift notch (34) and a interlock notch (44) all of which will align when the shift rails are in the axially centered neutral positions thereof. A shift shaft-shift finger assembly (76) extends generally transversely to the shift rails and is mounted in the shift mechanism housing (12) for axial movement along and rotational movement about its axis (122). The shift shaft (84) is axially movable in the space partially defined by the peripheral surfaces of the interlock notches. The shift shaft-shift finger assembly defines a gap (118) having a width (120) which is greater than the thickness (42) of one shift rail but less than the thickness of two shift rails and which is aligned with the shift finger ( 100) fixed for axial and rotational movement with the shift shaft (84) whereby alignment of the shift finger (100) with a selected shift rail will align the gap (118) with the selected shift rail allowing axial movement of the selected shift rail from the axially nondisplaced position thereof and will lock the remaining shift rails in the axially nondisplaced positions thereof. A single detent shaft (66) cooperates with neutral detents (46) and in-gear detents (48) provided in the shift rails and an adjustable resilient detent mechanism (180) and/or collars (158 and 160) provide verification of proper alignment of the shift finger with the middle (18 or 20) shift rails.
