Problems solved by technology

[0002] The existing traditional continuously variable transmission (CVT) transmission technology relies on the power belt and the friction between the driving and driven wheels with variable working diameters to transmit power. This transmission method cannot realize high-torque power transmission.

Abstract

The invention discloses a continuously variable transmission with synchronized gears. The continuously variable transmission comprises a driving wheel, a driven wheel and a power belt, wherein each of the driving wheel and the driven wheel comprises a power shaft, a fixed cone body fixedly mounted at one end part of the power shaft, a movable cone body sleeved by the other end part of the power shaft in a sliding manner, and a plurality of synchronized support bodies uniformly distributed along the center of the power shaft. The synchronized support bodies can move inwards or outwards in the radial direction through the movable cone bodies to adapt to the requirements of speed change on changes of radii of the driving wheel and the driven wheel. According to the continuously variable transmission, in the process that the synchronized gear is meshed with the power belt, the meshing position can be automatically tracked by the mechanical stress generated by the synchronization difference of the synchronized gear, that is, the synchronized gear can automatically change the arc positions in the speed change process between the driving wheel and the driven wheel, so that the complete meshing is realized, and high-power power transmitting is realized. The continuously variable transmission is simple in structure, and can realize a high-power continuously variable transmission mode.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a continuously variable transmission with synchronous tracking. Background technique [0002] The existing traditional continuously variable transmission (CVT) transmission technology relies on the power belt and the friction between the driving and driven wheels with variable working diameters to transmit power. This transmission method cannot realize high-torque power transmission. As far as automotive applications are concerned, the current occasions where CVT transmission technology is used are mostly limited to small-displacement vehicles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a continuously variable transmission with synchronous tracking. Using the principle of synchronous tracking, the continuously variable transmission between the driving and driven wheels is realized in a fully meshed trans...
