Travel driving device of sub-soiling cultivation soil preparation machine

Abstract

A travel driving device of a sub-soiling cultivation soil preparation machine comprises an engine, a gearbox, a front transmission shaft, a back transmission shaft, a front drive axle, a back drive axle, a power divider and an electric-hydraulic control device. A hydraulic pump forming the electric-hydraulic control device is connected with a hydraulic motor through an oil pipe, a guide hydraulic control handle is connected with the hydraulic pump and the hydraulic motor through an oil pipe, an output shaft of the engine is in transmission connection with the hydraulic pump through the power divider, an output shaft of the hydraulic motor is connected with an input shaft of the gearbox, an output shaft of the gearbox is connected with an input shaft of the front drive axle and an input shaft of the back drive axle through the front transmission shaft and the back transmission shaft, and the front drive axle and the back drive axle are respectively in transmission connection with a front drive wheel and a back drive wheel through axle shafts. The guide hydraulic control handle controls the hydraulic motor and the hydraulic pump so that advancing, reversing and stopping operations of a whole vehicle are achieved. The travel driving device can be optimally matched with the engine to obtain optimum power performance and driving performance, and is strong in passing capacity, good in controllability and safety, small in pollution and long in service life.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a driving device for driving a subsoiling tillage machine. Background technique [0002] At present, most of the plowing and leveling machines produced at home and abroad are designed to be used as agricultural machinery. There is no independent driving device in their structure. Machine farming. [0003] 1. Part of the subsoiling tillage and soil preparation machines produced in China are divided into two types according to the structure: single-wheel and double-wheel. Evolved; the two-wheel tillage and land preparation machine is driven by two wheels, and is an integrated unit composed of small walking tractors and agricultural implements. These two types of tillage and land preparation machines have relatively low maneuverability, mechanical tillage efficiency, and passing capacity. [0004] 2. The driving device of some land tillage machines has the same st...

Problems solved by technology

[0003] 1. Part of the subsoiling tillage and soil preparation machines produced in China are divided into two types according to the structure: single-wheel and double-wheel. Evolved; the two-wheel tillage and land preparation machine is driven by two wheels, and is an integrated unit composed of a small walking tractor and agricultural implements. These two types of tillage and land preparation machines have relatively low maneuverability, mechanical tillage efficiency, and passing capacity.

[0004] 2. The driving device of some land tillage machines has the same structure as the chassis of a car, that is, it is composed of an engine, a clutch, a gearbox, a transmission shaft, and a drive axle. Shift manipulation, on the one hand, will increase driver fatigue and reduce driving safety; on the other hand, it will increase the impact and dynamic load caused by frequent shifting, which will affect the service life of the drive train parts. The emission is large under working conditions, and it is easy to generate black smoke when working or accelerating at extremely high and extremely low speeds, thereby increasing the exhaust pollution of the engine. The driving performance of the machine is greatly affected
