摘要： A drive system for an electrically driven dump truck is capable of enabling electric motors for traveling to make full use of the output horsepower of the prime mover up to an output limit of the prime mover. A target motor horsepower corresponding to an operation amount of an accelerator pedal is calculated and an available maximum horsepower for the electric motors out of the maximum output horsepower of the prime mover is calculated in response to the actual revolution speed of the prime mover. The horsepower coefficient corresponding to the instantaneous revolution speed deviation is calculated. The available maximum horsepower for the electric motors is modified by the horsepower coefficient to determine a second target motor horsepower. The target motor horsepower is limited to not exceed the second target motor horsepower so as to control the torque of the electric motors.

摘要： A drive system of an electrically driven dump truck is capable of achieving an operational feeling in which the operation amount of the accelerator pedal is well balanced with the output horsepower of the electric motors, particularly at the time of slow traveling. To achieve this, the target motor output horsepower Pm0 corresponding to the operation amount of an accelerator pedal 1 is calculated. The target motor torque Tr1R, Tr1L is calculated on the basis of the target motor output horsepower Pm0 and the rotational speed ωR, ωL of electric motors 12R, 12L respectively. The acceleration torque limit values of the electric motors 12R, 12L corresponding to the operation amount of the accelerator pedal 1 are calculated, respectively. Then, smaller values are selected, as motor torque instruction values TrR, TrL, between the acceleration torque limit value and the target motor torque Tr1R, Tr1L to control inverters 73R, 73L, respectively.

The pantograph has a base frame, a bottom frame and a top frame rockably attached to the base frame, and a collector shoe supported by the top end portion of the top frame. A fixing member is disposed on the top end side of the top frame for fixing the pantograph, a hook device is disposed on the base frame, and a hook receiver is disposed on the base frame in order to receive the fixing member. When a frame assembly formed of the bottom frame and the top frame is folded, the fixing member becomes seated in the hook receiver and is pressed by means of the hook device, thereby securely fixing the frame assembly to the base frame.
