The present invention provides a continuously variable transmission with compound planetary transmission, aiming at prolonging the service life of the engine and the drive train. The key points of its technical scheme are that it includes an input shaft 1, a controllable torque device 4, an idle reverse gear mechanism 5, a one-way clutch 6, and an output shaft 7. The reverse gear mechanism 5 is connected, and the empty reverse gear mechanism is connected with the output shaft 7. There are several sequentially connected torque increasing units 2 between the input shaft 1 and the output shaft 7. The first torque increasing unit 2 is connected with the input shaft 1. One end of the common output element 23 is connected with the one-way clutch 6, and the other end is connected with the common output element 23 of each other torque increasing unit 2 and then connected with the controllable torque device 4, and the last torque increasing unit 2 is connected with the controllable torque device 4 The output elements 22 of the remaining torque increasing units 2 are connected with the input elements 21 of the next torque increasing unit 2 respectively.
Description
technical field [0001] The invention belongs to the field of transmissions, more specifically, it is a transmission for various ground vehicles, ships, railway locomotives, engineering machinery, various aerospace, aircraft, metallurgy, mining, petroleum, chemical industry, light industry, food, textile , Lifting and transporting machinery, machine tools, robots and military CVTs. Background technique [0002] At present, the commonly used continuously variable transmissions are designed according to the principles of friction and hydrostatics, etc. The power it can transmit is not high, and the efficiency is not high; expensive [0003] Materials and precision manufacturing can only be achieved, so the cost is high. Contents of the invention [0004] The invention overcomes the deficiencies of the prior art and provides a continuously variable transmission that prolongs the service life of the engine and the transmission system, has simple structure, convenient oper...
