PURPOSE:To improve the fuel consumption and to reduce noise and exhaust gas of an industrial vehicle by storing the excess output of a generator which is driven by an engine in a battery and supplying the insufficient energy from the battery. CONSTITUTION:A 3-phase AC generator 12 is driven by an engine 1 which is always operated at the rotating speed to become the optimum fuel consumption, and the output of the generator 12 is supplied through a transformer 15 and a rectifier 16 to a speed control thyristor chopper controller 17 of left and right drive DC motors 24a, 24b, a working hydraulic pump 20, a drive DC motor 19 and a battery 22. When the power consumptions of the motors 24a, 24b and, 19 are small, the excess output of the generator 12 is supplied to the battery 22, and when the power consumption exceeds the output of the generator, insufficient energy is supplied from the battery 22. In this manner, the fuel consumption is improved, and the noise and exhaust gas can be reduced. |
