Integral structure of transfer case and middle axle

Abstract

The invention relates to an integral structure of a transfer case and a middle axle, and belongs to the automobile manufacturing industry. The integral structure is characterized in that a planet carrier is respectively meshed with a gear ring and a sun gear by virtue of planet gears, the gear ring is connected with a driving cylindrical gear by virtue of a spline, a driven cylindrical gear is connected with a straight bevel gear planetary mechanism by virtue of a spline, the sun gear is connected with a through shaft by virtue of a spline, a differential lock I is fixedly connected with the through shaft, the gear ring is connected with the through shaft by virtue of the differential lock I, a differential lock II is connected with a front-axle input shaft, and the straight bevel gear planetary mechanism is connected with a speed reducer. The integral structure disclosed by the invention has the advantages that the integral structure is compact in structure, simple in process and light in weight, facilitates the arrangement of a transmission system of a finished automobile, and can ensure the longitudinal through radius of an off-road vehicle to be improved, thereby improving the cross-country performance of the off-road vehicle.

Description

technical field [0001] The invention belongs to the automobile manufacturing industry, and in particular relates to an integrated structure of a transfer case and a middle axle, which is suitable for 6x6 off-road vehicles. Background technique [0002] 6x6 off-road vehicles realize the front-to-back transmission of engine power through the transfer case, and the transfer case of most vehicles is arranged behind the gearbox. This arrangement is difficult to realize the layout of the whole vehicle for off-road vehicles with compact structure requirements. , and meet the off-road needs of the vehicle. Contents of the invention [0003] The invention provides an integral structure of a transfer case and an intermediate axle to solve the problem that it is difficult to meet the structural requirements of a compact off-road vehicle because the transfer case of the vehicle is arranged behind the gearbox to realize the overall vehicle arrangement and meet the off-road requirements...
