【発明の名称】1:1比率のロックアップクラッチを備える連続可変の静水圧トランスミッション
Document Type and Number:
Japanese Patent JP2002500733
Kind Code:
A
Abstract:
In a continuously variable hydrostatic transmission including a hydraulic pump unit driven by an input shaft, a grounded hydraulic motor unit, and an intermediate, wedge-shaped swashplate for developing torque on an output shaft in response to pumped exchanges of hydraulic fluid between the pump and motor units through swashplate ports, a ratio controller is provided to vary transmission ratio by changing the swashplate angular orientation and to engage a lock-up clutch directly mechanically coupling the input shaft to the output shaft when a 1:1 transmission ratio is set.
