Problems solved by technology

After the four-wheel drive transfer case is installed on the motor vehicle, the drive output end of the rear axle and the rear axle are not in the same horizontal plane, and the drive shaft connecting the drive output end of the rear axle and the rear axle has a large angle with the horizontal plane, resulting in It is prone to failure, and the existing four-wheel drive transfer case can only realize the conversion between rear drive and four drive
The defects that exist when applied to agricultural motor vehicles are: 1. The driving shaft and the driven shaft are not at the same level, and the drive shaft connecting the rear axle drive output and the rear axle has a large angle with the horizontal plane, which causes the agricultural motor vehicle to run. It is prone to failure; 2. The four-drive transfer case only has the drive mode of four-wheel drive; 3. The driving shaft and the driven shaft of the four-drive transfer case drive the rear axle and the front axle respectively, and cannot provide power for other equipment
The 4WD transfer case cannot power the oil pump

Abstract

The invention discloses a four-wheel-drive transfer case which comprises a case body, a front shifting fork, a rear shifting fork, an input shaft, an oil pump drive, an intermediate shaft, a front axle drive output shaft and a rear axle drive output shaft. The input shaft is arranged above the case body, the oil pump drive is arranged above the right side of the case body, the left end of the oil pump drive is connected with the right end of the input shaft through a bearing, a first shifting gear and a second shifting gear are arranged on the input shaft, the intermediate shaft is positioned in the middle of the case body, a first intermediate gear and a second intermediate gear are arranged on the intermediate shaft, the front axle drive output shaft is positioned on the left side below the case body, a front axle drive gear is arranged on the front axle drive output shaft, the rear axle drive output shaft is positioned on the right side below the case body, a rear axle drive gear is arranged on the rear axle drive output shaft, the front shifting fork is coupled with the first shifting gear which is meshed with the first intermediate gear, the rear shifting fork is coupled with the second shifting gear which is meshed with the second intermediate gear, the first intermediate gear is meshed with the front axle drive gear, and the second intermediate gear is meshed with the rear axle drive gear.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a four-wheel drive transfer case. Background technique [0002] The so-called transfer case is a device that distributes the power of the engine, and can output power to the rear axle, or to the front / rear axle at the same time. [0003] The rear axle drive output end of the existing four-wheel drive transfer case is not at the same level as the front axle drive output end. After the four-wheel drive transfer case is installed on the motor vehicle, the drive output end of the rear axle and the rear axle are not in the same horizontal plane, and the drive shaft connecting the drive output end of the rear axle and the rear axle has a large angle with the horizontal plane, resulting in It is prone to failure, and the existing four-wheel drive transfer case can only realize the conversion between the rear drive and the four-wheel drive. In addition, the existing four-wheel drive...
