| 摘要 |
Various applications or embodiments of a variable speed transmission concept wherein a variable speed drive and a proportional speed drive are operatively connected to a differential gear arrangement, such that variation of the speed ratio of the variable speed drive causes variation of the speed of an output shaft connected to the differential gear arrangement, said variable speed drive comprising a pair of variable diameter pulleys operatively interconnected by a belt. The variable speed transmission is combined with a flywheel to conserve and/or recuperate energy.
