Title:
出力シャフトに組込まれた構成要素を作動させる伝達比コントローラを有する連続可変水圧トランスミッション
Document Type and Number:
Japanese Patent JP3566728
Kind Code:
B2
Abstract:
To control the transmission ratio of a continuously variable hydrostatic transmission including an input shaft, an output shaft, an pump unit driven by the input shaft, a grounded motor unit, and an a wedge-shaped swashplate drivingly and pivotally connected to the output shaft in hydraulic fluid-communicating position between the pump and motor units, a ratio controller is provided having a hydraulically actuated piston incorporated internally of the output shaft. A pilot valve, also incorporated internally of the output shaft, operates to create differential fluid pressures at opposite end faces of the piston, forcing axial motion of the piston and ratio-changing pivotal movement of the swashplate linked to the piston.
