Title:
RATIO DIFFERENTIAL CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2001/009533
Kind Code:
A1
Abstract:
Both a gear transmission and a spherical surface frictional transmission are performed simultaneously in a power transmission of a continuously variable transmission so as to utilize the high efficiency of the gear transmission and utilize the continuously variable capability of the frictional transmission to the maximum. The continuous speed variation is made by a combination of a planetary gear speed reducer with a ratio (contact point radius ratio) dynamic frictional transmission device, a combination of the planetary gear speed reducer, a differential gear device, and the ratio dynamic frictional transmission device, and a combination of the differential gear device with the ratio dynamic frictional transmission device. The transmission is suitable for use in those devices requiring continuous speed variation such as cars, air conditioners, blowers and exhausters, pumps, and industrial machinery. When the transmission is assembled with a squirrel-cage motor in short-circuit operation which is simplest in structure and highest in efficiency among electric motors, its utility value is very high.
