FIELD: mechanical engineering.
SUBSTANCE: invention refers to the drive transfer box of the all-wheel drive vehicle. Transfer box contains the input shaft, the output shaft, high-low gear shifting mechanism, the output element, clutch, lockup clutch group, screw mechanism, transmission mechanism, barrel drum and switching mechanism. Switching mechanism is arranged in order to selectively switch between the position H4L and the position L4L in accordance with the rotational motion of the motor. H4L position is the position, in which the high-low transmission clutch is in the position, in which the high-speed transmission in the high-low transmission switching mechanism is installed. L4L position is the position, in which the high-low transmission clutch is in the position, in which the low-speed transmission in the high-low transmission switching mechanism is installed.
EFFECT: higher reliability and simplified design of the device.
