    摘要: A hydraulic drive system of a steerable wheel of a dump truck facilitates the attaching and detaching of a hydraulic motor and allows for a large hydraulic motor to be used. In the drive system, a wheel axle is rotatably supported within a receptacle seat supported on a yoke. The steerable wheel is rotatably mounted on the outer periphery of the receptacle seat. The steerable wheel and one end of the wheel axle are connected via a speed reducer. A motor casing 33 of a hydraulic motor is connected by bolts to the receptacle seat at an end of the seat remote from the steerable wheel so that the hydraulic motor can be attached to and detached from the receptacle seat by tightening and loosening the bolts.

    摘要: The gross output power of an engine distributed to at least one main machine and one auxiliary machine. A total load value calculation unit calculates the value of the lost power consumed by the auxiliary machine, and calculates the value of total load power by adding to this lost power value a target value for the main output power of the engine to be distributed to the main machine. A gross output value control unit controls the value of the gross output power so that the value of the gross output power becomes equal to the value of the total load power when the value of the total load power is less than a predetermined threshold value, and so that the value of the gross output power becomes equal to the above described threshold value when the value of the total load power is greater than the threshold value.
