Abstract

The invention relates to the field of agricultural machinery, in particular to a novel electric tractor driving structure and a driving method thereof.The novel electric tractor driving structure comprises a power output shaft installed at the tail of an electric tractor, a generator is installed at the tail of the electric tractor, the power output shaft is in transmission connection with the generator, and the generator is electrically connected with a master control module; the master control module is electrically connected with an energy converter, the energy converter is electrically connected with a magnetic suspension energy storage flywheel, the master control module and the energy converter are electrically connected with an electric tractor motor, and an output shaft of the electric tractor motor is in transmission connection with the power output shaft. The invention provides a magnetic suspension rotor energy storage device for an electric tractor to solve the problems that the specific power of an electrochemical battery of an existing electric tractor is not high enough, and a device capable of absorbing energy wasted due to frequent braking when the electric tractor works in a field does not exist.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a novel electric tractor driving structure and a driving method thereof. Background technique [0002] The magnetic levitation energy storage flywheel uses the magnetic levitation bearing, a new type of high-performance bearing without mechanical contact between the rotor and the stator, to support the high-speed operation of the flywheel rotor and the flywheel disc. The working principle of the magnetic levitation energy storage flywheel: When charging, the electric energy is input from the outside through the energy converter to drive the motor to move, which drives the flywheel to rotate at a high speed, and the flywheel disk stores the energy in the form of kinetic energy. When discharging, the rotation speed of the flywheel disc decreases, the kinetic energy decreases, and the mechanical energy is converted into the electrical energy required by the load through the gen...
