摘要

A transmission (12) for a vehicle (10) includes a gear shaft (24) having an external periphery (57) and a hub (54). The hub (54) is rotatably secured and axially moveably connected to the external periphery (57) of the gear shaft (24) and has a plurality of external teeth (62). The transmission (12) also includes a gear (56) connected to the gear shaft (24). An external periphery (66) of the gear defines teeth (67). The transmission further includes a shift collar (44) having a bore (64) through the shift collar (44). The shift collar (44) has internal teeth (65) that engage the teeth (62) of the hub (54). The gear and the shift collar (44) have a first configuration where all of the teeth (65) of the shift collar (44) are spaced from all of the teeth (67) of the gear (56) and a second configuration (70) where at least some teeth (65) of the shift collar (44) engage teeth (67) of the gear (56). The shift collar (44) defines a feature (71) for limiting the axial motion of the shift collar (44).
