    摘要: A self-propelled snowplow vehicle includes a vehicle frame equipped with an auger at a front end portion thereof and pivotally connected to a propelling frame equipped with driving wheels, and a frame lift mechanism for lifting the front end portion of the vehicle frame up and down relative to the propelling frame. The frame lift mechanism comprises an electro-hydraulic cylinder actuator having a piston rod and an electric motor rotatably driven to produce a fluid pressure for reciprocating the piston rod in response to operation of a manual operating switch. The snowplow vehicle also includes a control unit arranged to forcibly stop the electric motor when a predetermined time has elapsed after the operation switch is activated, the predetermined time being equal to an operating time of the cylinder actuator which is required to extend or contract the piston rod over a maximum stroke defined between a fully extended position and a fully contracted position of the piston rod.

    摘要: An electric working machine has an electric motor and a speed adjustment member for undergoing movement within a range of positions including a low speed range position in which the electric working machine travels at a low speed, a high speed range position in which the electric working range position in which the electric working machine travels at a speed intermediate of the low speed and the high speed. A potentiometer receives a voltage which varies in dependence on the position of the speed adjustment member within the range of positions. A control unit controls the electric motor in accordance with the variation of the voltage received by the potentiometer to vary a travel speed of the electric working machine so that a rate of change of the travel speed of the electric working machine is smaller when the speed adjustment member is in the intermediate speed range position than when the speed adjustment member is in each of the low speed range position and the high speed range position.

    摘要: Simplifying the controller of hybrid type drive unit. The output of a generator driven by engine is connected directly to a motor 7 through a converter or switching circuit 10 without being charged on any battery. The output of each phase of the generator is inputted to the converter 10. A timing controller 126 controls the conduction phase of a thyristor bridge 101 in the converter 10 so as to adjust the quantity of output power. A synchronous standard for phase control is formed based on output wave of an auxiliary winding 26 of the generator. A voltage detector 124 detects an applied voltage on the motor 7 as a motor rotation speed and the conduction angle is increased or decreased so as to maintain a detected voltage at a target value.

    摘要: In the working machine wherein the output of an engine generator is directly supplied to a motor for travel without using the intermediary of a battery, preventing the engine from slowing down. The generator G is directly connected to the motor 7 and there is no battery that stores the output of the generator G. CPU 102 decreases the power supply for the motor 7 when it has been anticipated that the engine revolutions will be decreased. The number of the engine revolutions is detected according to the period of the waveform of an output of the generator G. The alternating current waveform that has been drawn out from one phase of the winding of the generator G is shaped into a rectangular waveform. CPU 102 detects the period of the shaped waveform. When the detected period has become larger, the CPU 102 determines that the engine revolutions is about to decrease.

    摘要: A dual-motor electric vehicle having a control section that determines whether three conditions are satisfied, (1) that a straight-ahead travel instruction has been supplied to the vehicle, (2) that an actual number of motor rotations of an electric motor is less than a target number of motor rotations, and (3) that a motor control signal for bringing the actual number of motor rotations closer to the target number has reached a predetermined upper limit output value. When all conditions are satisfied for at least one of the electric motors of the dual-motor vehicle, the control section performs a downward motor-rotation correction process for at least one of motors by incrementally reducing one of the target number of motor rotations and the upper limit output value of the motor control signal until the respective actual numbers of rotations of the left and right motors substantially coincide with each other.

    摘要: Control section determines necessary acceleration of a transporting section in accordance with an actual transporting speed, and also determines a correction coefficient corresponding to the number of rotations of an engine from among correction coefficients having a characteristic of becoming closer to a value of one as the number of rotations of the engine increases. The control section multiplies the necessary acceleration by the correction coefficient to thereby provide corrected necessary acceleration, and controls rotation of a transporting drive motor in accordance with the corrected necessary acceleration. When the amount of electric power to be generated by a power generator driven by the engine has increased, the control section controls the opening of a throttle valve.
