The present invention relates to a multipurpose electric vehicle for agriculture having a working mode, which is driven by a battery to drive and perform farming work on a field topography. According to the present invention, the multipurpose electric vehicle for agriculture having a working mode comprises: a motor for working for outputting a PTO; a motor for driving; a control unit which controls the motor for working and the motor for driving; a front wheel driving shaft and a rear wheel driving shaft, which respectively transfer power of the motor for driving to a pair of front wheels and rear wheels, and which are placed on the same axis to have a clutch interposed between; a middle transmission which is able to output power of the motor for driving in multiple steps with different deceleration ratio, and to transfer the power to the rear wheel driving shaft; and a solenoid apparatus which operates the clutch through a fork. In addition, the control unit is able to control in a general driving mode, which drives only the motor for driving to drive with an output with a small deceleration ratio outputted from the middle transmission, and in a working driving mode, which drives the motor for driving and the motor for working at the same time, to drive with an output with a great deceleration ratio outputted from the middle transmission, to turn the clutch on by the fork by driving the solenoid apparatus, and to drive the front wheel driving shaft and the rear wheel driving shaft at the same time.

    본 발명은 배터리로 구동되고 밭 지형에서 주행 및 농사일을 수행할 수 있는 다목적 전기차를 제안한다. 본 발명의 다목적 전기차는, PTO 출력을 위한 작업용 모터, 주행을 위한 주행용 모터, 상기 작업용 모터 및 주행용 모터를 제어하기 위한 제어부, 한 쌍의 전륜 및 후륜으로 주행용 모터의 동력을 각각 전달하고, 그 사이에는 클러치가 개재되며 동축상으로 배치되는 전륜구동축 및 후륜구동축, 상기 주행용 모터의 동력을 감속비가 상이한 다단으로 출력 가능하고, 상기 후륜구동축으로 동력을 전달하는 중간트랜스미션, 그리고 포크를 통하여 상기 클러치를 조작하기 위한 솔레노이드장치로 구성된다. 그리고 제어부는; 주행용 모터만 구동시켜서 중간트랜스미션에서 출력되는 감속비가 작은 출력으로 주행하는 일반 주행모드와; 주행용 모터 및 작업용 모터를 동시에 구동시키고, 중간트랜스미션에서 출력되는 감속비가 큰 출력으로 주행하면서, 솔레노이드장치를 구동시키는 것에 의하여 포크에 의하여 클러치가 온되어 전륜루동축 및 후륜구동축이 동시에 구동되는 작업 주행모드로 제어할 수 있다.
