Description

technical field

[0001] The present invention relates to a hydraulic transformer and a control method thereof, and more specifically, the present invention relates to a hydraulic transformer with a virtual displacement variable hydraulic transformer of a machine-hydraulic pilot and a variable variable method. Background technique

[0002] The traditional structure of a hydraulic transformer consists of a plunger variable hydraulic motor with a plunger variable hydraulic pump. First, the plunger type variable hydraulic motor relies on the pressure oil to act on the plunger of the motor, so that the motor output shaft obtains a certain torque, and then the plunger type variable hydraulic pump applies the torque to the pump plunger again. Converted to pressure oil again. The change of the variable ratio can be realized by the variable of the hydraulic motor and the hydraulic pump.

[0003] Whether it is a plunger-type variable hydraulic motor or a plunger-type variable hydraul...
