Articulated hillside tractor with cascaded efficiency power transmission system

Abstract

The invention relates to an articulated hillside tractor with a cascaded efficiency power transmission system. A main machine includes power, a clutch, an efficient power transmission system, a cockpit, a front profiled hinge, a rear profiled hinge, a main bridge and a host walking system; an auxiliary machine includes an auxiliary bridge, a rack, a lifter, a steering arm and an auxiliary walking system; a high-power box, a gearbox and a combiner box are connected in series so as to form the efficiency power transmission system; the high-power box includes an input shaft, an input end gear pair, a power output shaft, a front gear pair, an outgoing end gear pair and a front power shaft; a universal gearbox is adopted as the gearbox; and the combiner box includes a power take-off gear pair, a power take-off shaft, a planetary gear train, a differential large gear, a front shaft, a rear shaft, an inter-shaft differential mechanism, a bevel gear pair, a main bridge differential mechanism, a main bridge half shaft, a hydrostatic transmission or a motor and a motor gear. The articulated hillside tractor has the advantages of front and back power interfacing, power stepless speed change, chassis exchange and simple production, and can assist in preventing the burnout of a transmission part.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an articulated mountain tractor with a series structure high-efficiency power transmission system. Background technique [0002] At present, the development of various agricultural machinery is becoming more and more mature, but there is no self-propelled power machinery suitable for mountainous / hilly environments to hang these modern machinery; The production of economic crops urgently needs to use mechanical operations to reduce labor intensity and improve production efficiency. [0003] Now the only general-purpose self-propelled power manipulator walking tractor in the mountainous area is obviously unable to realize the whole process of mechanization. Low and mountainous disc tractor is an articulated transport machine, since its birth in 1982, it has become an indispensable machine for mountainous / hilly rural transport. But its fatal flaw is that...

Problems solved by technology

Its features: the high-efficiency power transmission system enables the main engine to provide front and rear power output interfaces, continuously variable power transmission, four-wheel synchronous drive at any time, and half-track driving conditions; the high-efficiency power transmission system uses the general gearbox combination of automobiles or tractors to design different power segments and tractors with different needs; at the same time, it solves the problems of partial burnout of the gearbox when the tractor is driving on a long slope, the tractor can drive in mountains and paddy fields, the tractor turns in situ, and improves the annual utilization of the tractor.
