Abstract

The invention discloses a four-wheel-drive system, comprising a drive shaft, a power takeoff device and a transmission. A shell of the power takeoff device is connected with a shell of the transmission; the drive shaft is inserted into identical insertion holes in the shell of the power takeoff device and the shell of the transmission, and the drive shaft is in drive connection with an output gearof the transmission; the drive shaft is provided with a first shaft shoulder; the cylindrical surface of the first shaft shoulder is in smooth transition with the surface of the drive shaft; a firstsealing ring is arranged on the first shaft shoulder in manner of hooping; the first sealing ring is used for sealing a gap between the shell of the transmission and the drive shaft; the cylindrical surface of the first shaft shoulder is provided with a guide flange; the cylindrical surface of the guide flange is in smooth transition with the surface of the first shaft shoulder; a second sealing ring is hooped onto the drive shaft; the second sealing ring and the first sealing ring are arranged in manner of spacing; and the second sealing ring is used for sealing a gap between the shell of thepower takeoff device and the drive shaft. The four-wheel-drive system disclosed by the invention can be improved in sealing property.

Description

technical field [0001] The invention relates to the technical field of automobile power systems, in particular to a four-wheel drive system and an automobile. Background technique [0002] The four-wheel drive system is a power system that distributes the power of the engine to the four wheels of the car. According to the location of the engine, it is usually divided into two types: front drive system and rear drive system. Among them, the engine in the front drive system has two layout forms, that is, the engine is placed horizontally and the engine is placed vertically. For the front drive system with the engine transversely mounted, the power transmission part mainly includes the engine, power take-off and transmission. The engine is connected to the transmission, and the power is output to the transmission. Both the transmission and the power take-off are set on the drive shaft of the car. The transmission transmits the power of the engine to the drive shaft to drive t...
