Abstract

The invention discloses a drive axle of an articulated tractor, comprising a drive axle shell assembly, a speed reducer assembly, a differential mechanism assembly (10) and a brake assembly (4), wherein the speed reducer assembly is set to be a two-stage speed reduction device, and composed of a main speed reducer assembly (2) and a rim speed reducer assembly (3); the main speed reducer assembly (2) and the rim speed reducer assembly (3) are arranged at the both ends of the drive axle shell assembly (1) respectively and connected via a half shaft (5); the main speed reducer assembly (2) adopts a spiral bevel gear transmission mechanism; and the rim speed reducer assembly (3) adopts a planetary speed reduction transmission mechanism with three planetary wheels. The drive axle disclosed by the invention is provided with the two-stage speed reduction device, so that the complete machine is large in input torque, high in transmission efficiency, stable in working, good in overall motion rigidity, and stable in product quality.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an articulated tractor drive axle. Background technique [0002] As the main part of the chassis transmission system, the drive axle is mainly used to increase the torque transmitted from the engine, distribute the torque to the left and right drive wheels, and make the wheels on both sides have a differential function. Various forces from the frame. The current tractor drive axles all use a reducer assembly, which limits the output torque of the main engine and the transmission efficiency. Affect the quality and stability of the entire product. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an articulated tractor drive axle equipped with a two-stage reduction device, so that the input torque of the whole machine is large, the transmission efficiency is high, the work is stable, the overall motion rigidity is...
