摘要： This invention relates to a speed change controller of a running hydraulic motor. A hydraulic motor used as a driving source for running construction machinery such as a power shovel can switch its rotating speed between a high speed (low torque) and a low speed (high torque) so as to cope with the change of the running state of the construction machinery. The present invention judges the running state not only by the running load but also by other factors, corrects the speed set by an operator on the basis of the overall judgement result, makes a speed change control of the hydraulic motor so as to provide this corrected speed and insures always a smooth running operation. After the rotation speed of the running hydraulic motors (10, 10') is switched and set by high speed/low speed setting means (31), a set condition (high speed or low speed) is corrected not only by the judgement result of running load state means (30) for judging the running load state but also by the judgement result of engine rotation state judgement means (37) for judging the state of engine rotation speed, and the like. When switch valves (6, 6') are operated to provide a rotation speed (high speed or low speed) after this correction, the pressure oil outputted from rotation direction switch valves (48, 48') is supplied selectively in response to the valve operation to either oblique plate variable angle actuators (7, 7') for low speed or to oblique plate variable angle actuators (8, 8') for high speed and the oblique plate angle of the running hydraulic motors (10, 10') is varied so as to obtain the rotation speed after correction. The apparatus in accordance with the embodiment of the present invention is mainly mounted to and used in construction machinery such as a power shovel.

摘要： An arrangement and a process are useful for operating a drive unit for motor vehicles, in particular agricultural and building machinery. The arrangement comprises a controllable internal combustion engine (2), a continuously variable hydromechanical power split transmission (6) and a control device (3), which for starting and operating at low speed under load first maintains the speed of the internal combustion engine below the rated speed and reaches a first speed by reduction of the delivery volume of the adjusting pump (13) of the hydrostatic branch (15). The speed is further raised by increasing the speed of the internal combustion engine. The speed of the vehicle is then increased by controlling the demultiplication of the hydrostatic-mechanical power split transmission (6).

摘要： A hydraulic control device for a continuously variable vehicle transmission (T) having a closed hydraulic circuit disposed between a hydraulic pump (P) and a hydraulic motor (M), with at least one of said hydraulic pump (P) and said hydraulic motor (M) being of the variable displacement type. The hydraulic pump (P) is driven by an engine (E) and the hydraulic motor (M) is connected to the road wheels (W) and is driven by hydraulic pressure from the hydraulic pump (P). A pair of relief valves (4, 5) are disposed between the two oil passages (La, Lb) of the closed hydraulic circuit extending between the hydraulic pump (P) and the hydraulic motor (M), each of which are for relieving the pressure from one oil passage to the other oil passage (La) which has the higher pressure when the continuously variable transmission (T) is driven by driving forces from the engine (E) to drive the road wheels (W), and has a relief pressure setting controlled so as to increase as the speed of rotation of the engine (E) increases. The other relief valve (5) which relieves the pressure from the other oil passage (Lb) which increases in pressure when said continuously variable transmission (T) receives driving forces from the road wheels (W), has a relief pressure setting controlled so as to increase as the speed of the motor vehicle increases.

摘要： A time-dependent engine output power characteristic curve for an engine output power to vary therealong to a target value which corresponds to an indication of intention of the driver for acceleration or deceleration (e.g., the amount of depression of the accelerator pedal) is established based on the difference (ΔPs) between a target engine output power (Psr) and an actual engine output (Pso) power. Then, a target rate of change of the rotational speed of the engine and a target rate of change of an indication of an engine load are established so that the actual engine output power varies along the engine output power characteristic curve, and the throttle valve and the continuously variable transmission of the engine are controlled using the target rates thus established.

摘要： A method of controlling speed reduction ratio for a continuously variable speed transmission comprises a running mode control method which is carried out when an accelerator opening is opened, an engine brake mode control method which is carried out when said accelerator opening is substantially closed and a transient control method which is carried out over a predetermined period of time (TEB) when the control is shifted from a state under the engine brake mode control to a state under the running mode control. The transient control method comprises the steps of obtaining a corrected R-REF engine speed immediately after the shift to the running mode control (S4,S6), by adding a difference (OFFSET) between the actual engine speed and the R-REF engine speed to the R-REF engine speed set corresponding to the current accelerator opening, obtaining a further corrected R-REF engine speed during a predetermined period of time (TEB) following the shift (S11,S6), by adding a correction which is obtained by gradually decreasing the speed difference with time (S9,S10,S11) to the R-REF engine speed, and controlling the speed reduction ratio (57) so that the actual engine speed coincides with the corrected R-REF engine speed over the predetermined period of time.
