| 20120252613 | TREADLE-DRIVE ELLIPTICAL WHEEL TRANSMISSION WHEEL SERIES WITH PERIODICALLY VARIED SPEED RATIO - The present invention is structured by using one or both of an active wheel and a passive wheel to be constituted by a bimodal elliptical wheel, so that in the reciprocal treadle performed by the human's feet, when the feet input forces at different angles to an active wheel shaft combined on the active wheel through cranks and treadle shafts of the treadles, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle. | 10-04-2012 |
| 20120252614 | TREADLE-DRIVE ECCENTRIC WHEEL TRANSMISSION WHEEL SERIES WITH PERIODICALLY VARIED SPEED RATIO - The present invention is structured by using one or both of an active wheel and a passive wheel being composed of an eccentric transmission wheel and being combined with a synchronous transmission belt for forming an eccentric wheel transmission wheel series, so that in the reciprocal treadle performed by the human's feet, when the feet input forces at different angles from the treadle shafts of the treadles to an active wheel shaft combined on the active wheel through cranks, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle. | 10-04-2012 |
| 20130130851 | TREADLE-DRIVE ECCENTRIC WHEEL TRANSMISSION WHEEL SERIES WITH PERIODICALLY VARIED SPEED RATIO - The present invention is structured by using one or both of an active wheel and a passive wheel being composed of an eccentric transmission wheel and being combined with a synchronous transmission belt for forming an eccentric wheel transmission wheel series, so that in the reciprocal treadle performed by the human's feet, when the feet input forces at different angles from the treadle shafts of the treadles to an active wheel shaft combined on the active wheel through cranks, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle. | 05-23-2013 |
| 20140031156 | MULTI-SPEED DRIVE FOR TRANSFERRING POWER TO A LOAD - In a first aspect, the invention is directed to a multi-speed drive for controlling the speed of a load that is driven from a crankshaft of an engine. The multi-speed drive permits the speed of the load to be adjusted based on one or more parameters, such as vehicle speed, engine RPM, battery charge level (e.g. when the load is an alternator), coolant temperature (e.g. when the load is a cooling fan), engine power demand from the vehicle driver, water level in which the vehicle is driving (e.g. when the load is a cooling fan whose blades could be damaged or could cause damage to other vehicle components if they impact water during use). The speeds provided by the multi-speed drive may include two or more non-zero rotational speeds, or two or more non-zero rotational speeds and a zero speed, or one non-zero rotational speed and a zero speed. | 01-30-2014 |
| 20140135157 | TREADLE-DRIVE TRANSMISSION WHEEL SERIES WITH PERIODICALLY VARIED SPEED RATIO AND HAVING INWARD PACKING AUXILIARY WHEEL - In the present invention, one or both of an active wheel or a passive wheel is composed of an eccentric transmission wheel and is combined with a synchronous transmission belt for forming an eccentric wheel transmission wheel series, so that when the feet input forces at different angles from the treadle shafts of the treadles to an active wheel shaft combined on the active wheel through cranks, the active wheel forms different transmission speed ratios relative to the passive wheel according to the treadle angle, and random inward packing is performed to the transmission belt ( | 05-15-2014 |
| 20140171240 | Noncircular Synchronous Transmission Pulley Set Having Periodically Varying Speed Ratio and Circumference Compensating Function - The present invention is to install a transmission belt between two noncircular synchronous transmission pulleys, thereby providing a non-sliding synchronous transmission feature between the belt and the pulleys, when the noncircular active pulley is driven to synchronously link the noncircular passive pulley to rotate through the transmission belt, a noncircular synchronous transmission pulley set having periodically varying speed ratio and circumference compensating function is formed, through the two pulleys being formed with certain noncircular wheel shapes, during the synchronous transmission, the circumferences of the two wheel shapes can be mutually compensated. | 06-19-2014 |
| 20140171241 | TRANSMISSION WHEEL SERIES WITH PERIODICALLY VARIED SPEED RATIO AND HAVING RECIPROCALLY DISPLACING AUXILIARY PULLEY FOR STORING/RELEASING KINETIC ENERGY - The present invention is installed with a unidirectional transmission device at the active side, so when a transmission belt is tightened while the active pulley driving a passive pulley in periodically varied speed ratios, an auxiliary pulley ( | 06-19-2014 |
