Continuously Variable Transmission with Side Speed Regulating Lead Screw

Abstract

The invention relates to a continuously variable transmission with side speed regulating lead screw, and it comprises: a housing, a driving flat disc system, a power input system, a middle flat disc system, a power output system, a compaction system, a speed regulating ratio system of the middle flat disc, and serial and parallel structures. Since the previously most successful continuously variable transmission is the CVT continuously variable transmission, such continuously variable transmission transmits power depending on the conical disc and steel belt, and the limitation of the continuously variable transmission restrains the extensive application of such continuously variable transmission, whereas the continuously variable transmission of the invention transmits power depending on the mutual compaction between the driving flat disc and the middle flat disc as well as between the middle flat disc and the driven flat disc. The invention aims to solve the problem of too small transmission torque existing in previous continuously variable transmissions, and it realizes the objective of regulating the speed ratio by the movement of the middle flat disc up and down.
