Triple-drive axle

Abstract

The invention provides a triple drive axle. The two-axle final reducer is composed of a two-axle distributor and a two-axle reducer. The second axle transfer gear is an asymmetrical conical planetarygear differential, Carrie of planetary gear, first planet gear, Rear shaft gear, Front axle gear and differential lock between axles, the planetary gear carrier is vertically fixed to the shaft end ofthe input shaft of the second axle, the first planetary gear is rotatably mounted on the shaft end of the planetary gear carrier and meshes with the rear half shaft gear and the front half shaft gearrespectively to form an asymmetrical conical planetary gear train; The second axle reducer is a symmetrical conical planetary gear differential. The triple drive axle of the invention has a compact structure, and the whole vehicle is lifted to be lightweight; meanwhile, the problem of the complex split structure of the cylindrical gear planetary system in the existing distributor is solved, and the requirements of the whole vehicle arrangement and the off-road performance are met. The triple drive axle of the invention is characterized in that the structure of the triple drive axle is compact, the weight of the whole vehicle is lifted, and the problem of the complex split structure of the cylindrical gear planetary system in the existing distributor is solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmission, and relates to a drive axle assembly and a transfer case assembly of a vehicle, in particular to a triple drive axle, especially suitable for off-road vehicles driven by 8×6. Background technique [0002] In order to improve the loading capacity and vehicle passability, heavy-duty off-road vehicles generally adopt multi-axle drive. For 8×6 vehicles, the power of the engine is distributed to the second, third and fourth axles through the transfer case, and most vehicles use an independent transfer case assembly. According to the position of the transfer case, the conventional transmission system is divided into two types: one is that the transfer case is arranged between the second bridge and the third bridge, and the transfer case is connected with the gearbox through the transmission shaft; the other is the transfer case The transfer case is arranged between the first axle and the ...

AI Technical Summary

Problems solved by technology

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a triple drive axle to solve the problem that the structure of the independent transfer case or the transfer case integrated with the gearbox is not compact and affects the weight reduction of the whole vehicle. At the same time, it solves the problem of complex transfer structure of cylindrical gear and planetary row, and meets the requirements of vehicle layout and off-road performance.
