Title:
TRACTOR TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/257188
Kind Code:
A1
Abstract:
A tractor transmission, comprising a housing. An input bevel gear shaft, a shaft, a middle gear shaft, and an output gear shaft are connected in the housing; the input bevel gear shaft is linked with the shaft by means of a spline housing; the shaft is in engagement transmission with a first gear ring of an epicyclic speed reduction mechanism by means of an engagement tooth; the input bevel gear shaft is in engagement transmission with an HMT input bevel gear; an HMT output bevel gear is transmittingly connected to a first sun gear of the epicyclic speed reduction mechanism; an output gear is sleeved on a first planet carrier of the epicyclic speed reduction mechanism; an input gear is sleeved on the middle gear shaft; the middle gear shaft is transmittingly connected to the output gear shaft; and the output gear shaft is provided with a planetary speed reduction mechanism and an engaging tooth sleeve. By using a parallel combination of mechanical transmission, hydraulic transmission, and the epicyclic speed reduction mechanism, the tractor transmission has the advantage of high efficiency of mechanical transmission and the shifting comfort brought by continuously variable transmission of the hydraulic transmission, such that the applicability of the whole machine is greatly improved.
