Hybrid power tractor

Abstract

The invention discloses a hybrid power tractor. The tractor comprises a tractor chassis and a tractor body, a left front wheel, a left rear wheel, a right front wheel and a right rear wheel are arranged on the lower end surface of the tractor chassis through a suspension system, the left front wheel, the left rear wheel, the right front wheel and the right rear wheel are all free-steering tractorwheels, the four wheels of the four-wheel drive tractor can turn with any angle, so that operation efficiency of the automatic plowing tractor is improved and operation requirement for multiple working conditions can be adapted. The attachment between the wheels and the ground is ensured when the a tractor passes an uneven road section, and the probability that the tractor is out of control due tosuspending wheels because of uneven road surface is greatly lowered. According to the hybrid power tractor, a storage battery is adopted as a power source, the functions of generator charging and commercial power quick charging are realized, and simultaneous charging is realized. A four-wheel drive motor and a farm tool power output motor are controlled independently, various motors are controlled by corresponding motor controllers, and mutual non-interference is realized.

Description

technical field [0001] The invention relates to the technical field of tractor control systems, in particular to a hybrid tractor. Background technique [0002] At present, the tractors used in my country's agricultural production are still mainly traditional fuel tractors, with complex structures, large energy consumption and serious pollution. Most tractors are rear-wheel drive, front-wheel steering, insufficient adhesion, and limited steering angle. Steering wheel, accelerator, and brake are all driven by mechanical parts to realize steering and acceleration and deceleration. The structure is complex and the service life of mechanical parts is limited. The present invention is a new type of hybrid tractor. The key components such as walking, steering and braking can realize electronic automatic control, which is largely different from the mechanical transmission control of traditional fuel tractors. This hybrid tractor is more suitable for intelligent Autopilot. At pre...

Problems solved by technology

[0003] Most traditional tractors use two-wheel drive, which does not allow all the mass to fall on the driving wheels. The utilization rate of the vehicle mass for the improvement of ground adhesion is low, so the maximum adhesion is small, making the wheels easier to slip, thus Affected maximum traction

The steering of the tractor depends on the mechanical structure, so the steering angle of the tractor is limited, and it cannot move in all directions. It is difficult to rotate 360° and move laterally when the tractor is running.

During the operation of the self-driving tractor, when the operation reaches the end of each line, it is necessary to turn around and go to the next line of work. Due to the limited steering angle and large turning radius, it cannot meet the line-entry requirements of the self-driving tractor. In the automatic driving mode, it is difficult to automatically complete the U-turn and enter the line operation. It is necessary to switch to the non-automatic driving mode first, and complete the U-turn with manual intervention. When the automatic driving mode is satisfied, switch to the automatic driving mode
