摘要： A first motor 3 and a second motor 4 of variable displacement type are in parallel to each other connected to a hydraulic pump 2 in a closed circuit, through which the output torque from the first motor 3 is transmitted to an output shaft 6. A clutch control unit 10 controls a clutch device 15 as: when the engine speed is N1, which is the case where the accelerator pedal is fully depressed, the clutch is disengaged at the vehicle speed v1. When the engine speed is N3 (

摘要： An electric driving wheel type work vehicle has a traveling motor 21, an inverter 313 for supplying the motor with three-phase power converted from DC power, a pre-driver circuit 312 for supplying a gate signal 316 to the inverter 313 on the basis of an input PWM signal, a controller 311 for outputting to the pre-driver circuit the PWM signal 315 for controlling the driving of the motor 21, parking brake means 10, and parking brake condition detection means 12 that detects the condition of the parking brake means 10. When the parking brake condition detection means 12 detects the parking brake means 10 has been operated, the pre-driver circuit 312 cuts off the output of the gate signal 316, or the input of the PWM to the pre-driver circuit 312 is cut off.

摘要： This invention includes a hydraulic pump (9), a working implement (107) having a lift cylinder (13) driven by a hydraulic fluid supplied from the hydraulic pump (9), an operating device (104) for operating the working implement (107), a traveling motor (7) for driving wheels, and a main controller (100). When the lift cylinder (13) fails to operate despite an extending instruction being imparted to the lift cylinder (13) via the operating device (104), the main controller (100) reduces a limit value for an increase rate of a torque required in the traveling motor (7) to a value smaller than that applied when the lift cylinder (13) operates. With this configuration, occurrence of wheel slip during lifting of an object to be carried can be reduced.
