A planetary gear tracking and meshing continuously variable transmission is provided with an active conical disc group, a passive conical disc group and annular driving belts / chains, wherein the annular driving belts / chains are connected to the active conical disc group and the passive conical disc group in a sleeving mode. The planetary gear tracking and meshing continuously variable transmissionis characterized in that planetary gears are correspondingly arranged at the position between movable conical discs and fixed conical discs of the active conical disc group and the passive conical disc group in a mode of surrounding conical disc driving shafts; a planetary gear variable-diameter gear ring formed by surrounding of the planetary gears can conduct variable-diameter movement along with changing of the axial distances between the movable conical discs and the fixed conical discs; the driving belts / chains are connected with the planetary gear variable-diameter gear ring, and the planetary gears mesh with the driving belts / chains; when the planetary gear variable-diameter gear ring conducts the variable-diameter movement, the planetary gears can rotate synchronously along with moving of meshing tooth positions of the driving belts / chains so as to ensure that meshing teeth of the planetary gears are kept to always adapt to the meshing tooth positions of the driving belts / chains. The planetary gear tracking and meshing continuously variable transmission has the beneficial effects that the real sense of tooth meshing driving continuously variable transmission is realized, the planetary gear tracking and meshing continuously variable transmission can adapt to high-speed vehicles with high power and rapidly accelerating, and the application range is greatly expanded.
Description
[0001] Technical field [0002] The invention relates to a planetary gear tracking meshing continuously variable transmission, which belongs to the technical field of mechanical transmission, in particular to a continuously variable transmission capable of gear meshing transmission. Background technique [0003] At present, most of the continuously variable transmissions use friction transmission, because of their small transmission torque, low load capacity, poor resistance to overload and impact resistance, large slip rate, and low mechanical efficiency; some also have pulsating output and discontinuous power flow; The power transmission needs to increase the normal pressing force, the power loss is large and the load on each bearing is increased, the bearing is easily damaged, the effective contact surface for power transmission is small, theoretically it is line contact or point contact, and the local stress is large , It is easy to cause scratches or glue on the working s...
