Title:
CONTINUOUSLY VARIABLE TRANSMISSION HAVING A PERIODIC DISPLACEMENT WAVEFORM WITH A CONSTANT VELOCITY PORTION
Document Type and Number:
WIPO Patent Application WO/2014/144242
Kind Code:
A3
Abstract:
A continuously variable transmission (CVT) can include a rotary cam member defining an internal cam surface operably engaged with a cam follower assembly for generating a displacement waveform with a constant velocity portion. A ratio control assembly can restrain the cam follower assembly for reciprocal linear movement and can scale the reciprocal linear movement between at least 0% and 100%, inclusive, in response to an angular orientation of the ratio control assembly. An output assembly can convert the scaled reciprocal linear movement into rotary movement of an output shaft. A CVT method can include generating a periodic displacement waveform with a constant velocity portion, scaling the periodic displacement waveform between at least 0% and 100%, inclusive, with a ratio plate, where the scaling is in response to an angular orientation of the ratio plate, and converting the reciprocal linear movement into rotary output with a combiner.
