SERIES HYBRID COMBINE-HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a series hybrid combine-harvester so as not to stop a vehicle accompanied with unexpected stop of a generator while adopting a smallest possible (small output) engine and generator to improve fuel consumption performance of the engine which becomes a driving source of the motor.SOLUTION: A series hybrid combine-harvester comprises: a generator 81 which is driven by engine output; a motor 82 which is driven by electric power supplied from the generator 81; an electric machine control unit 85 which controls the generator 81 and the motor 82; a travel unit 1 which causes a vehicle to travel by use of rotation power from the motor; a vehicle speed setting operation device OD which sets a vehicle speed according to an operation position; and an engine rotation sensor S2 which acquires a rotational number of the engine. The series hybrid combine-harvester is constructed to check output torque of the motor 82 so that a power generation load of the generator 81 does not exceed an allowable load.
