Problems solved by technology

The planetary pinion is installed on the driving transmission gear with two pin shafts. It is difficult to ensure the coaxiality of the upper and lower planetary gears, which in turn affects the meshing accuracy between the planetary pinion and the sun gear. The strength of the shaft is weak and the strength of the pin shaft is small, the transmission torque is small, and even the half shaft is broken, the service life is low, the noise is too large, and the transmission efficiency is low
In addition, the reduction box body and the support arm of the drive axle are integrated. If different wheelbase sizes need to be matched, different castings are required. The manufacturing cost is high and the cycle is long, so the selection range changes little, and it is difficult to be suitable for different types of electric vehicle designs. Require

Abstract

The invention relates to a new electric tractor comprising a rack, a traction hook, an electric power supply device, a drive axle driven by a direct current motor, a speed regulation handlebar, a motor speed controller, a universal wheel and a travelling wheel. The invention also relates to a charger base for charging storage batteries of the electric tractor, which comprises a base, a charger, aback cover board, a main baffle block, an assistant baffle block and a support board. The invention has the advantages of compact, small and exquisite integral structure, flexible and convenient operation and wide application range. The storage batteries of the electric tractor can be conveniently and rapidly taken out from or placed on a machine or the charger base, and the two storage batteriesare alternately used to enhance the utilization efficiency of the machine.

Description

technical field [0001] The invention relates to a tractor, in particular to a novel electric tractor. [0002] The invention also relates to a charger stand for charging battery packs of electric tractors. Background technique [0003] In the prior art, most of the known electric tractors are stand-up or seat-drive vehicles, and the structure adopts vertical or horizontal driving wheels as the power unit, and the steering wheel steering system. The overall structure is relatively complex, the volume is large, and the manufacturing cost is high. The working range required for moving and turning is poorly applicable in a small area. [0004] The towing hooks commonly used on electric tractors have a fixed distance hook and an adjustable distance hook. Neither clamps effectively and both have uncoupling during motion. [0005] In the prior art, the used battery packs of known electric tractors are all fixed installation type, generally not suitable for frequent disassembly a...
