Abstract

The invention relates to the technical field of transmissions, and particularly discloses a stepless speed change servo planetary gear transmission capable of being broken and twisted. The stepless speed change servo planetary gear transmission comprises a cross planetary input shaft, a transmission unit, a CVT (continuously variable transmission) main belt wheel, a CVT auxiliary belt wheel, an auxiliary belt wheel connecting shaft, an auxiliary belt wheel connecting shaft small gear and an output shaft connecting large gear, wherein the transmission unit is in transmission connection with the cross planetary input shaft, and the CVT main belt wheel is in transmission connection with the transmission unit, the CVT auxiliary belt wheel is in transmission connection with the CVT main belt wheel, the auxiliary belt wheel connecting shaft, the auxiliary belt wheel connecting shaft small gear and the output shaft connecting large gear are in transmission connection, and the output shaft connecting large gear is in transmission connection with the cross planetary input shaft. Compared with an AT transmission, a DCT transmission and a CVT transmission, the transmission is large in bearing torque, fast in speed change, smooth in process, long in service life, simple in structure and low in manufacturing cost; and meanwhile, the barriers of manufacturing technologies of various types of transmissions are avoided, and the effects of energy conservation and emission reduction are achieved.

Description

technical field

[0001] The invention relates to the technical field of transmissions, in particular to a servo planetary gear transmission with continuously variable speed and torque. Background technique

[0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. At present, the types of transmissions include AT transmissions, DCT transmissions and CVT transmissions.

[0003] However, the above-mentioned transmission also has its corresponding disadvantages. Its manufacturing process is complicated, its cost is high, its torque transmission loss is large, and the speed change process is not smooth. The belt and the pulley are easy to slip, easy to overheat and easy to be damaged. In view of this, a continuously variable transmission is proposed. Contents of the invention
