摘要： A vehicular body oscillating mechanism (31) is provided between a frame (3) of an automotive vehicular body (2) and a stabilizer (18) thereby to sway the vehicular body (2) arcuately in a rightward and/or leftward direction about a pivot point (A) between right and left rear wheels (6, 7) when the stabilizer (18) is set on the ground for a load handling operation. This means that, after the stabilizer (18) is set on the ground for a load handling operation, the vehicular body (2) can be swayed arcuately laterally in a rightward and/or leftward direction together with a load lifting mechanism (12). Therefore, at the time of a load handling operation with the stabilizer (18) set on the ground for stabilization of the vehicular body (2), it is possible to turn and move the load lifting mechanism (12) into a rightward or leftward direction to adjust the position or direction of lifted freight goods in case it is deviated from a specified unloading spot in a lateral direction. Namely, in a load handling operation, the load lifting mechanism (12) can be adjusted in a lateral direction to dump lifted freight goods exactly on a specified unloading spot.

摘要： A hydro-static transmission travel system for a working machine enables the working machine to travel over a range from low speed to high speed with a simplified circuit arrangement. By referring to a machine traveling speed (vehicle speed) based on a detected signal from a rotation sensor, a controller computes respective target tilting amounts of hydraulic motors 10, 20 and controls the tilting amount for the hydraulic motors and a clutch. Depending on whether the traveling speed exceeds a setting speed as a reference boundary, the controller selectively switches over a drive mode between low-speed four-wheel drive, in which travel units 12, 22 are both driven, and high-speed two-wheel drive, in which the front-wheel side hydraulic motor 10 is controlled to zero displacement and only the rear-wheel side travel unit 22 is driven.

摘要： One of the mode lamps 38a, 38b and 38c of the mode indicator 38 corresponding to the current steering mode is turned on yellow and the other mode lamps are turned on green or turned off, thereby indicating whether front wheels 1, 1 and rear wheels 2, 2 are at neutral. A controller 39 does not operate a mode changing valve 24 even with an instruction outputted from a mode change switch 35 when the front and rear wheels are not at neutral, and operates, in response to an instruction outputted from the mode change switch 35, the mode changing valve 24 to establish a steering mode corresponding to the instruction when the front and rear wheels are at neutral. Also, the mode indicator 38 is controlled to always indicate, as the current steering mode, one corresponding to the steering mode actually established by the mode changing valve 24. With those features, in a working vehicle in which the mode of steering front and rear wheels can be changed over between two-wheel steering and four-wheel steering, a steering system having superior operability and high reliability can be provided.

摘要： To keep one of three hydraulic pumps unaffected by variations in torque of the remaining hydraulic pumps when the three hydraulic pumps are used, displacements of the first and second hydraulic pumps are controlled based on their own delivery pressures P1,P2 and a pressure P3′ obtained by reducing through a reducing valve 14 a delivery pressure P3 from the third hydraulic pump, while a displacement of the third hydraulic pump 3 is controlled only by its own delivery pressure P3. The pressure oil delivered from the third hydraulic pump 3, therefore, remains unaffected by variations in delivery flow rates from the first and second hydraulic pumps 1,2, in other words, by variations in their torque consumptions, so that the third hydraulic pump is assured to provide a stable flow rate.
摘要翻译：当使用三个液压泵时，为了保持三个液压泵中的一个不受剩余液压泵的扭矩变化的影响，基于其自身的输送压力P1，P2和获得的压力P3'来控制第一和第二液压泵的位移通过减压阀14从第三液压泵减小输送压力P3，而第三液压泵3的排量仅由其自身的输送压力P3控制。因此，从第三液压泵3输送的压力油不受来自第一和第二液压泵1,2的输送流量的变化的影响，换句话说，它们的扭矩消耗的变化使得第三液压泵是保证提供稳定的流量。
