A power shift gearbox assembly for a combine harvester

Abstract

The invention discloses a power gearshift transmission assembly used for a combine harvester. The power gearshift transmission assembly comprises an input shaft, a gearshift shaft, an output shaft, a clutch output half shaft, a differential and a hydraulic hand brake device. The input shaft is connected with an output shaft of a hydraulic motor of the combine harvester via an input connector, power is transmitted to the differential via the output shaft to realize first, second and third shifts, and the differential and the hydraulic hand brake device are mounted on the clutch output half shaft. The input shaft is provided with a first-second shift driving gear and a third-shift driving gear, the gear shift shaft is provided with a second-shift gearshift gear, a third-shift gearshift gear, a first-shift intermediate gear, a gearshift shaft output gear, a second-third shift clutch, a main gearshift shaft oil channel and a gearshift shaft oil drain channel, and the output shaft is provided with a first-shift gearshift gear, an output shaft output gear, an output shaft pinion, a first-shift clutch, a main output shaft oil channel and an output shaft oil drain channel. The power gearshift transmission assembly is simple in structure, capable of receiving electric signals and convenient to operate.

Description

technical field [0001] The invention relates to a combine harvester, in particular to a power shift gearbox assembly for the combine harvester. Background technique [0002] The combine harvester needs to keep the engine speed stable when it is working, so the walking speed can only be changed through the walking continuously variable transmission system and gearbox, which means that the driver has to operate the steering wheel and continuously variable block, increasing the difficulty of operation. In view of the above-mentioned problems of the combine harvester, the inventor has designed a power shift gearbox assembly for the combine harvester. The power shift gearbox can receive electrical signals to realize gear shifting, and is easy to operate and realize automatic control . Contents of the invention [0003] The main purpose of the present invention is to provide a new power shift gearbox assembly for a combine harvester, which is easy to operate and easy to realiz...
