摘要： A response control system for a hydrostatic-mechanical transmission. In this system, it is determined in digging/moving operation whether an actual speed ratio which is the ratio of the revolution speed of the output shaft to the revolution speed of the power source is equal to a specified value or less, and if so, a target speed ratio which is a target value for the ratio of the revolution speed of the output shaft to the revolution speed of the power source is set, limiting the amount of change in the target speed ratio per unit time. Based on the target speed ratio thus set, the angle of at least either of discharge controlling swash plates is controlled, thereby reducing vehicle acceleration at the primary stage of digging. In order to slow down the response to a change in load during digging operation, a constant indicating the response to a change in engine revolution is set small in proximity to a target engine revolution speed. With this arrangement, the response of the transmission to a change in load during digging operation can be retarded.

摘要： Disclosed is a clutch changeover circuit suitably used for a multi-stage stationary non-stage transmission. Valve bodies of pressure regulating valve (211, 221, 231, 241) are respectively provided with throttle passages (311, 321, 311, 341) communicating therewith in such a manner that hydraulic oil flows to the clutch sides when they are closed, since the sliding of the clutches or damage thereto can occur if pressure regulating valves having good override characteristics are used. Accordingly, at the time of changing over the clutch, since hydraulic oil flows at least by a portion corresponding to the rate of flow of leaking oil, it is possible to prevent the clutches from sliding or becoming damaged while using regulating valves having good override characteristics. In addition, the circuit is provided with common oil passages (301, 302) leading to a plurality of clutches corresponding to speed stages that are not adjacent to each other, and pressure regulating valves (411, 421) and pressure reducing valves (412, 422) that are used jointly for the plurality of stages are provided in these common oil passages, thereby simplifying the circuit configuration by reducing by half the number of these conventionally employed valves.

摘要： A target engine revolution speed is calculated based on the throttle position of an engine such that the amount of change in the target engine revolution speed with respect to time is limited. According to the target engine revolution speed thus calculated, a target motor speed ratio, which is a target value for the ratio of the revolution speed of a motor in a hydrostatic transmission unit to the revolution speed of the engine, is set. With this target motor speed ratio, the angle of at least either of discharge controlling swash plates is adjusted.
