The invention provides an oil-saving automobile four-wheel driving device. The oil-saving automobile four-wheel driving device comprises a central axle upper differential mechanism and a rear axle compression package axle shaft clutch. The central shaft upper differential mechanism comprises a chain gear and a planetary gear carrier which are connected with an axle body. Shaft pins of the planetary gear carrier are provided with movable planetary gears. A main gear sleeve is arranged on one side of each planetary gear. The other sides of the planetary gears are in meshing connection with a sector gear sleeve. A driving bevel gear is connected to the outer diameter of the sector gear sleeve. A gear hub is connected with the sector gear sleeve. A locking gear hub is connected with the axle body. A gear shifting sleeve is meshed with the driving bevel gear, the gear hub and the locking gear hub in sequence and slides on the driving bevel gear, the gear hub and the locking gear hub to conduct gear shifting. The rear axle compression package axle shaft clutch comprises two opposite axle shafts which are each connected with an axle shaft keyboard and an axle shaft connecting keyboard. A differential mechanism locking keyboard is arranged on one axle shaft and located between the two axle shaft connecting keyboards. Movable gear shifting sleeves connect the axle shafts, the axle shaft keyboards, the axle shaft connecting keyboards and/or the differential mechanism locking keyboard into a whole.
