Title:
連続可変水圧トランスミッションの改良型伝達比コントローラ
Document Type and Number:
Japanese Patent JPH09511320
Kind Code:
A
Abstract:
A continuously variable hydrostatic transmission includes an input shaft connected to drive a hydraulic pump unit, a grounded hydraulic motor unit, and an output shaft. A wedge-shaped swashplate is pivotally mounted to the output shaft in driving connection to receive output torque resulting from the exchange of pressurized hydraulic fluid between the pump and motor units through slots in the swashplate. A hydraulically actuated ratio controller shifts the axial positions of spherical bearings mounting a pump portplate in the hydraulic pump unit and a motor portplate in the hydraulic motor unit to adjust the swashplate angle relative to the output shaft axis and thereby change transmission ratio.
