20130023366 | Methods and Devices for Improving the Performance of CVTs - Methods and devices for improving the performance of CVT's (Continuous Variable Transmissions) that utilize a cone with one torque transmitting member, a cone with two opposite torque transmitting members, cone with one tooth (single tooth cone), and a cone with two opposite teeth. Said methods and devices include but are not limited to: a mechanism for changing the axial position of a cone quickly and accurately (see FIG. | 01-24-2013 |
20130090197 | LARGE-TORQUE CHAIN-GUIDE TYPE CONSTANT RATIO/CONTINUOUSLY VARIABLE TRANSMISSION - A large-torque chain-guide type constant ratio/continuously variable transmission is disclosed. The transmission comprises transmission rollers (A, B), an endless transmission chain or belt (C) and two chain guiders (D, E) respectively arranged beside the two transmission rollers. Each chain guider comprises n groups of grooved-pulleys, and each group comprises m grooved-pulleys. Each grooved-pulley rotates freely around a grooved-pulley axis, and an angle α is formed between the axis of at least one grooved-pulley in each group of grooved-pulleys and a roller axis of the transmission roller matched with the same grooved-pulley. The angle α enables the chain entering the chain guider and the chain leaving the chain guider to move a certain axial distance, i.e. a chain distance, on the transmission rollers, wherein the chain distance is required to be larger than the width of the chain or the belt. The endless transmission chain passes sequentially through the pulley groove of at least one grooved-pulley in one group and the driving roller under the guidance of the chain guider, and is guided to a driven roller after winding n circles around both the chain guider and the driving roller. Whereafter, the transmission chain passes sequentially through the pulley groove of at least one grooved-pulley in one group and the driven roller under the guidance of the chain guider, and returns to the driving roller to be closed after winding n circles around both the chain guider and the driven roller. The transmission has small size and compact structure, and can output a large torque. | 04-11-2013 |

Said methods and devices include but are not limited to: a mechanism for changing the axial position of a cone quickly and accurately (see FIG. | 05-23-2013 |
20130310205 | CVT WITH EXTENDED TRANSMISSION RATIO RANGE | 11-21-2013 |
20140213398 | Method for Increasing Transmission Ratio Changing Duration of CVTs - A method for substantially increasing the duration at which the transmission ratio for a “CVT comprising of two cones mounted on separate shafts that are coupled by a means for coupling” can be changed, by changing the axial position of said cones independent of each other, and by utilizing a means for tensioning that can provide and/or remove slack in said means for coupling as needed as to allow the axial positions of said cones to be changed independent of each other. | 07-31-2014 |
