HYBRID SYSTEM BASED ON HYDROSTATIC TRANSMISSION

摘要

PURPOSE: A hybrid system based on HST is provided to minimize the size of electronic equipment which operates as an engine, a motor, and a generator by creating high torque. CONSTITUTION: A hybrid system based on HST comprises a battery(15), a controller(11), a HST unit(30), a first gear train(7), a second gear train(8), a first electronic device(9), and a second electronic device(22). The controller charges current in the battery and monitors the signal from each sensor. A HST unit is installed between the output shaft(1a) of an engine(1) and the driving shaft(4) of a differential unit(6). The HST unit controls a gear ratio. The first gear train is connected to the output shaft of an engine. The second gear train is connected to the driving shaft of a differential unit. The first electronic device is installed in the driving shaft connected to the first gear train.
