Multifunctional speed changing box

Abstract

The invention discloses a multifunctional speed changing box which comprises a box body, an input shaft assembly, and left and right output shaft assemblies which are in power transmission connection with the input shaft assembly by a middle speed changing shaft assembly, wherein the left and right output shaft assemblies are fixedly sleeved with bull gears respectively; a reverse gear shaft assembly serving as transfer power transmission is arranged between the middle speed changing shaft assembly and the input shaft assembly; a brake shaft assembly is arranged among the middle speed changing shaft assembly and the left and right output shaft assemblies, and comprises a brake input gear which is in power transmission connection with the middle speed changing shaft assembly, left and right brake output gears meshed with the bull gears correspondingly, and steering yokes which control the left and right brake output gears to form the power transmission connection with the two end faces of the brake input gear respectively and correspondingly; and the brake shaft assembly is in power transmission connection with a second output shaft assembly by a transition shaft assembly. The speed changing box comprehensively has functions of speed changing, steering, parking, main output, second output, clutch and the like.

Description

technical field [0001] The invention relates to a multifunctional gearbox, in particular to a speed change mechanism applied in a rice and wheat miniature combine harvester. Background technique [0002] The speed change mechanism in the present rice-wheat combine harvester has a single function, is inflexible and unreliable. Existing speed change mechanism can't possess comprehensive functions such as speed change, steering, parking, main output, second output and clutch simultaneously, therefore, need to design a new multifunctional gearbox to synthesize above-mentioned functions. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention aims to provide a multifunctional gearbox applied to a miniature rice-wheat combine harvester, which is comprehensively equipped with variable speed, steering, parking, main output, second output and clutch And other functions, and flexible idling, reliable shifting, flexible s...
