A powershift transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. is a multi-stage transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. that allows gear changes to occur under full load without interrupting the flow of power. This is made possible by clutches that shift automatically or multi-plate clutch packs within the transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. . Unlike conventional manual transmissions Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. , there is no need to disconnect the drive power via a manual clutch. Powershift transmissions Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. are particularly used in vehicles that require continuous traction when shifting gears, such as construction machinery, tractors, armored vehicles, and heavy trucks. Advantages include smooth operation, reduced wear, and a longer service life under heavy load cycles and changing operating conditions.
