Title:
HIGH-EFFICIENCY CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2011/129554
Kind Code:
A2
Abstract:
The present invention relates to a high-efficiency continuously variable transmission, and more particularly, to a high-efficiency continuously variable transmission that is a type of stepless transmission enabling easy and continuous change of speed through the use of a planetary gear, a hydraulic pump, a hydraulic motor, a flow control valve, etc. Specifically, the transmission of the present invention uses an input planetary gear device and a regenerative planetary gear device, so as to be capable of continuously changing speed of a high load power at high transfer efficiency from an infinite gear ratio to a gear ratio allowable by the planetary gear, driving the hydraulic motor by means of oil pressure discharged by the hydraulic pump connected to the input planetary gear device to regenerate rotational force at the output end, and enabling continuous change in speed according to the volume of hydraulic fluid discharged by the hydraulic pump through operation of the flow control valve.
