Problems solved by technology

[0003] Traditional tractors often adopt the method of arranging counterweights at the front end to suppress the adverse effects caused by axle load transfer, but counterweights will increase the energy consumption of the tractor during driving; in addition, when the tractor is working in the field, it cannot adjust the distribution in real time according to the change of working conditions. The size of the heavy block can not give full play to its overall performance

Abstract

The invention relates to the technical field of electric tractors, in particular to a quick counterweight system of an electric tractor and a control method of the system. The counterweight system is arranged on an electric tractor body and comprises a power battery pack (1), a power battery mounting frame (2), a bearing frame (3), a sliding adjusting mechanism (4) and a control system; the characteristic of flexible arrangement of the power battery pack of the electric tractor can be fully utilized, no additional balancing weight is needed, the operation stability can be improved, the energy loss is reduced, and the traction efficiency is improved. The steering capacity of the whole machine and the rear wheel slip rate can be observed in real time, the position of the power battery pack can be adjusted with high precision, distribution of the shaft weight of the front shaft and the rear shaft is changed, and the functions of rapidly balancing weight and improving the operation effect are achieved.

Description

technical field [0001] The invention relates to the technical field of electric tractors, in particular to an electric tractor fast counterweight system and a control method thereof. Background technique [0002] As the most important agricultural power machinery, tractors need to complete a variety of field operations, transportation operations and fixed site operations. The traction force of the tractor will lead to the transfer of the load on the front and rear axles; when the traction force is too large, the load on the front axle will be seriously reduced or even zero, which will seriously affect the adhesion of the front wheels, and the tractor will lose its steering ability, resulting in the risk of tilting and overturning. Excessive loads lead to serious rear wheel slippage, increased tire wear, increased energy loss, and the driver's handling stability and safety cannot be guaranteed. Therefore, adjusting the tractor's front and rear axle loads becomes critical. ...
