    摘要: The current operational condition is discriminated as being the vehicle propulsion condition or the performing work condition. When the vehicle propulsion operational condition is discriminated, the maximum engine revolution speed is limited to a first revolution speed and the maximum displacement is limited to a first displacement value. When the performing work condition is discriminated, the maximum engine revolution speed is limited to a second revolution speed equal to or lower than the first revolution speed and the maximum displacement is limited to a second displacement value higher than the first displacement value. The first and second revolution speeds and the first and second displacement values are so determined that the first revolution speed multiplied by the first displacement value at least as relating to pressure for vehicle propulsion on level ground is less than the second revolution speed multiplied by the second displacement value as relating to the pressure for below the range of torque limitation control. By this, the pump output flow during vehicle propulsion on level ground is made lower than while performing work and, during vehicle propulsion, reduction of the pressure loss is made possible. Even with the identical pump pressure, the effective motor pressure is increased, so that its output torque can be increased. Because also the maximum displacement of the motor can be reduced according to the reduction of the maximum pump output flow amount, the construction of the hydraulic circuit can be made more compact.

    摘要翻译: 目前的运行状况被认为是车辆推进条件或执行工作状态。 当识别出车辆推进操作条件时,最大发动机转速被限制到第一转速,并且最大位移被限制在第一位移值。 当鉴别出执行工作状态时,最大发动机转速被限制在等于或低于第一转速的第二转速,并且最大位移被限制为高于第一位移值的第二位移值。 第一和第二转速以及第一和第二位移值被确定为至少与水平地面上的车辆推进的压力相关的第一转速乘以第一位移值小于第二转速乘以第二转速 与低于转矩限制控制范围的压力有关的位移值。 由此,在水平地面的车辆推进期间的泵输出流量低于执行工作时的泵输出流量,并且在车辆推进期间,可以降低压力损失。 即使使用相同的泵压力,有效的电机压力也会增加,从而可以提高其输出转矩。 因为根据最大泵输出流量的减少,也可以减小电动机的最大排量,可以使液压回路的结构更加紧凑。

    摘要: The displacement of a variable displacement hydraulic pump (1) which is driven by a diesel engine (27) is so controlled as to be set to a first target displacement to keep a pump pressure higher than a load pressure by a predetermined target value, or a second target displacement to limit an input torque on the basis of the pump pressure. Provided is a stand-by flow rate control portion (65) which outputs a third target displacement larger than the minimum value of said first target displacement. The displacement of the pump (1) is controlled so as to be set to the third target displacement when the third target displacement is output from the stand-by flow rate control portion (65).

The means for revolution speed control (33) performs normal control by increasing or decreasing the revolution speed of the engine according to the amount by which the vehicle driving pedal (6) is depressed, and, when it is decided that the amount by which the vehicle driving pedal (6) is depressed is decreasing, performs controlled slowing down by reducing the revolution speed of the engine while delaying its reduction amount. And, when during working the engine revolution speed is being adjusted by the use of the vehicle driving pedal (6), controlled slowing down is prevented even when the amount by which the vehicle driving pedal (6) is depressed is decreasing.
