Electric tractor gravity center adjusting device

Abstract

The invention provides an electric tractor gravity center adjusting device which comprises a power battery, a power battery bracket, a gravity center horizontal-adjusting mechanism and a gravity center longitudinal-adjusting mechanism. The power battery is used for providing gravity required for gravity center adjusting; the power battery bracket is used for installing and fixing the power battery and providing anti-collision protection for the power battery; the gravity center horizontal-adjusting mechanism located below the power battery bracket is used for adjusting a gravity center of an electric tractor in a horizontal direction; and the gravity center longitudinal-adjusting mechanism located below the gravity center horizontal-adjusting mechanism is used for adjusting the gravity center of the electric tractor in a longitudinal direction. According to the electric tractor gravity center adjusting device provided by the invention, the characteristic of large weight of an electric tractor battery can be fully utilized, gravity center adjusting can be carried out in the horizontal direction and the longitudinal direction without extraly adding balancing weight blocks, the gravity center adjusting range is wide, the precision is high, the tractive efficiency and the stability of the electric tractor can be improved, the energy can be saved, and the environment can be protected.

Description

technical field [0001] The invention relates to the technical field of electric tractors, in particular to an electric tractor gravity center adjustment device. Background technique [0002] When the tractor is transported or cultivated, due to the heavy cargo transported and the large traction force required, the driving wheels will slip severely and the head will be tilted, which will lead to a significant decrease in the traction efficiency and stability of the tractor, and even tractor tipping over. Dangerous situation: In sloped fields or roads, tractor tipping is more likely to occur, which poses a certain threat to the safety of electric tractor drivers. In order to reduce the slippage of the drive wheel to improve the traction efficiency of the electric tractor, prevent the head of the electric tractor from tilting to ensure the stability of the electric tractor, minimize the increase of the counterweight to reduce energy consumption and soil compaction damage, etc.,...

AI Technical Summary

Problems solved by technology

[0004] (1) Additional counterweights are required, and too few counterweights are weak in adjusting the center of gravity, and too many counterweights will increase tractor driving resistance and energy consumption, which is not conducive to energy conservation and environmental protection;

[0005] (2) The vertical adjustment range of the center of gravity is limited, and the center of gravity can only be adjusted by extending the front of the tractor, and the adjustment range is small, and it cannot be adjusted in the range behind the front axle of the tractor. When the electric tractor goes downhill, it is not conducive to improving the longitudinal stability of the electric tractor sex;

[0006] (3) The center of gravity cannot be adjusted horizontally. When the tractor is driving or farming along the contour line on a slope, it is easy to roll over, and the inability to perform horizontal adjustment is not conducive to improving the lateral stability of the electric tractor;

[0007] (4) The adjustment accuracy is not high, and the adjustment position only has two fixed positions: retraction and extension, which is not conducive to fine adjustment, and the structure is relatively complicated
