摘要： The invention relates to a dual motor hydraulic hybrid transmission. The transmission comprises a power source, a hydraulic circuit including a pump drivingly engaged with the power source and two displacement units, a hydraulic accumulator assembly including high and low pressure accumulators, one or more control valves, and an output shaft drivingly engaged with the first hydraulic displacement unit. The displacement units are in fluid communication with the hydraulic pump. The accumulators are in fluid communication with the hydraulic circuit. The second hydraulic displacement unit is drivingly engaged with the output shaft. The control valves are configured to selectively fluidly connect the hydraulic pump to the first hydraulic displacement unit while fluidly disconnecting the hydraulic pump from the second hydraulic displacement unit; and, simultaneously, fluidly connect the hydraulic accumulator assembly to the second hydraulic displacement unit while fluidly disconnecting the hydraulic accumulator assembly from first hydraulic displacement unit.

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.
