INTEGRALLY FORMED STEPLESS SPEED-CHANGE STRUCTURE CONSISTING OF HYDRAULIC VARIABLE DISCHARGE-AMOUNT VANE PUMP AND VANE MOTOR

摘要

PURPOSE:To improve power transmission efficiency by operating the rotor and vanes of a hydraulic variable discharge-amount type vane pump and the rotor and vanes of a hydraulic vane motor in a same container. CONSTITUTION:The rotor and vanes of a hydraulic variable discharge-amount type vane pump and the rotor and vanes of a hydraulic vane motor are operated in a same container. Therefore, the necessity of the suction port, discharge port, and oil pipes for a hydraulic pump and a motor is obviated, and the loss due to the oil flow can be reduced, and power transmission efficiency can be improved.
