Abstract
A sub-transmission of a transfer unit includes a shift sleeve that moves to a neutral position N where it does not engage with a high-speed gear set to an input shaft or a low-speed gear set to a deceleration system, and thereafter engages with the high- or low-speed gear to transfer the driving force of the input shaft to an output shaft in the form of a high-speed or low-speed driving force. The output shaft has an outer periphery provided with an annular friction member in contact with the input shaft, for reducing the rotational speed of the input shaft, and thereby decreasing gear screeches during a changeover between low- and high-speed positions, even if a free-running torque is transferred to the input shaft from a hydrodynamic automatic transmission.
