Abstract:
1. A treadle-drive eccentric wheel transmission wheel series with periodically varied speed ratio and having inward packing auxiliary wheel, wherein one or both of an active wheel and a passive wheel is composed of an eccentric transmission wheel and 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, and random inward packing is performed to the transmission belt ( 100 ) of the engage end of the eccentric passive wheel ( 413 ) during the transmission for stabling the operation; In the treadle-drive eccentric wheel transmission wheel series with periodically varied speed ratio and having inward packing auxiliary wheel of the present invention, the active wheels or the passive wheels to constitute the eccentric wheel series include the round eccentric wheel, non-round eccentric wheel, bimodal elliptical wheel and round wheel to constitute both or one of the active wheels and the passive wheels, so as to incorporate with timing pulleys and transmission belt, or chain wheels and the transmission chain, or directly constituted by the gear set with the function of periodically varied speed ratio; According to the treadle-drive eccentric wheel transmission wheel series with periodically varied speed ratio and having inward packing auxiliary wheel of the present invention, the transmission speed ratio can achieve the maximum while close to the maximum treadling force angle, and the maximum transmission speed ratio is defined as the rotation speed angle displacement of the active wheel being capable of relatively transmitting a higher rotation speed to the passive wheel compared to other angle displacements during the whole period of the active wheel performing transmission to the passive wheel; the main constitutions of the eccentric transmission wheel series ( Transmission belt ( Round active wheel ( Eccentric passive wheel ( The eccentric transmission wheel series ( Auxiliary wheel press helve ( Auxiliary wheel ( In the transmission wheel series composed of the round active wheel (
