High-power step-less variable transmission case for agricultural machinery

Abstract

The invention discloses a high-power step-less variable transmission case for agricultural machinery, and the high-power step-less variable transmission case comprises an outer shell and an input shaft. The high-power step-less variable transmission case for the agricultural machinery further comprises a driving gear, a driven gear, a variable speed shift gear transmission mechanism, a steering clutch brake mechanism, a left steering transmission gear wheel and a right steering transmission gear wheel which are all arranged on the input shaft, wherein the input shaft is driven by a hydraulic step-less transmission HST (hypersonic transporter); the driving gear is engaged with the driven gear; the left steering transmission gear wheel and the right steering transmission gear wheel are bothin transmission connection with the steering clutch brake mechanism through gear engagement; the variable speed shift gear transmission mechanism is in transmission connection with the steering clutch brake mechanism through gear engagement; and the left steering transmission gear wheel and the right steering transmission gear wheel are respectively coupled with a transmission shaft which corresponds to a traveling mechanism on one side. The high-power step-less variable transmission case for the agricultural machinery can be used for efficiently enhancing the transmission property, realizingshifting speed control and simultaneously performing clutch brake, bearing high-power output and resisting frequency with fluctuation change of loads so as to prevent the transmission case from cracking.

Description

[0001] technical field [0002] The invention relates to the technical field of agricultural machinery equipment, in particular to a technology of a steplessly variable transmission box for high-horsepower agricultural machinery equipment. [0003] Background technique [0004] In view of the high viscosity of paddy fields in southern my country, the original low-horsepower diesel engine found that the gears of the transmission box were worn too fast during the actual farming process, which affected the accuracy of farmland operations. Therefore, this kind of working environment requires a high-horsepower mechanical drive device. However, The transmission box of the existing high-horsepower mechanical drive device is prone to cylinder explosion when it is subjected to high and low frequently changing loads. [0005] Contents of the invention [0006] The purpose of the present invention is to provide a high-horsepower agricultural machinery that can effectively improve th...
