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.
Description
technical field [0001] The invention relates to a driving mechanism for automobiles, in particular to a fuel-saving four-wheel drive device for motor vehicles, especially for SUVs. Background technique [0002] Four-wheel drive means that the power of the engine is transmitted to the four wheels to drive the car. Four-wheel drive forms can be divided into three categories: part-time four-wheel drive, timely four-wheel drive and full-time four-wheel drive. [0003] The applicant has previously filed an application for the invention of a vertical four-wheel drive mechanism for a car, which can realize rear-wheel drive four-wheel drive, full-time four-wheel drive and four-wheel drive lock. In the process of continuous research and development, people found that the fuel consumption of this longitudinal four-wheel drive mechanism is relatively high, especially when used in SUVs or off-road vehicles. [0004] Therefore, need a kind of new four-wheel drive device, both can keep ...
