達装置。 A main transmission with a plurality of transmission shift positions, and a Hi-Low transmission connected in series to the main transmission.
a transmission consisting of an auxiliary transmission with two shift positions, and a transfer that enables the drive system of the output shaft of the transmission to be selectively switched to two-wheel drive or four-wheel drive. A power transmission device for a vehicle equipped with the above, wherein when the transfer is switched to a two-wheel drive state in a combination of shifting between the auxiliary transmission and the transfer, the main transmission transmits the power after the transfer. To prevent the transmission system from shifting to a shift position that would generate excessive force that could destroy the power transmission system.
A power transmission device for a vehicle, characterized in that the switching mechanism of the main transmission is provided with an interlock mechanism.
