STEPLESS CLOSED PLANETARY HYDROMECHANICAL VARIABLE-SPEED DRIVE Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: stepless closed planetary hydromechanical variable-speed drive is intended for expansion of adjustment range of rotation of driven shaft from zero to straight line and includes two planetary rows and torque converter. Epicyclic gear of first planetary row is made fast to driven shaft. Shaft of sun gear of same row is made fast to runner of torque converter. Carrier of first row has two-ring satellite gears. Sun gear of second planetary row is made fast to impeller of torque converter. Epicyclic gear of this row is made as one unit with central gear of first planetary row. Carrier with pair satellite gears is made fast to driven shaft. Driving shaft is made fast to body of torque converter, reactor of torque converter and carries of first planetary row. EFFECT: expanded adjustment range of proposed rive. 1 dwg
