Tractor axle with planetary speed reducing mechanism

Abstract

The invention discloses a tractor axle with a planetary speed reducing mechanism, which consists of an axle main speed reducing mechanism assembly, a planetary gear speed reducing mechanism assembly and a wheel hub mechanism assembly. The main speed reducing mechanism assembly is internally provided with a main speed reducing assembly and a main speed reducing differential lock operating mechanism; the planetary gear reducing mechanism assembly is respectively designed at two ends of the axle main reducing mechanism assembly and is internally provided with the planetary gear reducing assembly;and the wheel hub mechanism assembly is provided with a brake system mechanism and a wheel hub seat. The planetary speed reducing mechanism assembly is designed at two sides of the axle main speed reducing mechanism assembly, so that a second deceleration can be realized after the main deceleration of the axle; the planetary gear speed reducing transmission and coaxial output are adopted; and theplanetary speed reduction mechanism assembly is compact in structure, high in strength and large in transmission torque. Under the condition of the same wheel edge output torque, the design strengthof the transmission system and the main reducing gear can be reduced, so that the transmission system and the main reducing gear assembly can be designed to be smaller and more compact, and the purposes of reliable use and light weight manufacture can be achieved.

Description

technical field [0001] The invention relates to a vehicle axle for a tractor with a planetary reduction mechanism, and belongs to the technical field of tractor transmission system manufacture. Background technique [0002] The structure of the tractor transmission system is relatively complicated. The transmission and the axle are usually integrated. The transmission line is usually engine-clutch-transmission-auxiliary transmission-axle main deceleration-half shaft-wheel, after transmission, auxiliary transmission, axle main deceleration The reduction transmission of three kinds of reduction mechanisms. Since the final stage is the axle main deceleration, the axle main deceleration also bears the largest force. In order to improve the reliability of the transmission system, the spiral bevel gear modulus of the axle main deceleration is generally designed to be relatively large, so the structural size is difficult. The shrinkage adds great difficulty to the lightweight manu...

Since the final stage is the axle main deceleration, the axle main deceleration also bears the largest force. In order to improve the reliability of the transmission system, the spiral bevel gear modulus of the axle main deceleration is generally designed to be relatively large, so the structural size is difficult. Shrinking, adding great difficulty to the lightweight manufacturing of the tractor and the arrangement of surrounding accessories
