Independent steering and four-wheel driving power-driven orchard work vehicle

Abstract

The invention relates to a orchard-used self-propelled independent steering and four-wheel driving power-driven orchard work vehicle comprising a frame structure, an single-wheel independent driving and independent steering mechanism, an overall steering and overall walking mechanism, a corner signal and revolving speed signal sensor and a central control unit and s storage battery. The frame structure is used for supporting other mechanical mechanisms and providing a chassis platform. The single-wheel independent driving and independent steering mechanism is provided with a direct current motor, a reducer and a direct current motor driver which are used for outputting corresponding revolving speed and torque needed in walking and controlling sense of rotation of car wheels, and is provided with a stepping motor, a stepping motor driver and a reducer which are used for steering independently. The overall steering and overall walking mechanism comprises four single wheel independent driving and independent steering structures same in structure. The corner signal and revolving speed signal sensor transmits signals to data acquisition cards to process and transmits back to computers to finish information feedback. The central control unit is used for controlling driving modes of each wheel. The storage battery is used for supplying power to all electric power mechanisms, driving mechanisms and control systems. The orchard-used self-propelled independent steering and four-wheel driving power-driven orchard work vehicle can realize overall movement by various driving modes and strong in topography adaptability.

Description

technical field [0001] The invention relates to an orchard operation vehicle, in particular to a self-propelled four-wheel independent drive and independent steering electric orchard operation vehicle adapted to the characteristics of orchards in my country. Background technique [0002] my country is the world's largest fruit producer and the world's largest fruit consumer, and its fruit planting area and output both rank first in the world. In 2010, the orchard area was 115.439 million hectares, and the output was 128.652 million tons. The rapid development of the fruit planting industry has also promoted the continuous progress of my country's orchard machinery, but generally speaking, my country's orchard operation machinery is still in its infancy. The impact and limitation of poor driving stability cannot meet the needs of orchard operations. Therefore urgently need to develop and utilize a kind of orchard operation machine that is suitable for the situation of my cou...

Problems solved by technology

Due to the characteristics of the orchard's own environment and the working requirements of the operating machinery, the existing electric vehicle technology is difficult to realize in the orchard, so it is of great significance and value to study orchard electric vehicles that are suitable for orchard operations and maintain the original advantages of electric vehicles.
