AI Technical Summary

Problems solved by technology

[0002] The CVT continuously variable transmission used in the automotive field uses the friction force generated between the pressure steel belt or the chain and the V-shaped groove walls of the two cone wheels to transmit torque, and the planetary friction mechanical continuously variable transmission used in the mechanical field also uses friction. Torque is transmitted by force. The existing continuously variable transmission technology transmits small torque through friction, which cannot be applied to the power system of high-power fuel vehicles and the continuously variable transmission device of large machinery, and it is easy to generate more when torque is transmitted by friction. If the temperature rise is too high, the pressure steel belt or chain will be damaged easily. When the internal combustion engine accelerates rapidly, the friction surface will slide, resulting in acceleration lag and affecting the driving experience.
