Problems solved by technology
[0002] At present, the automatic transmission technology that is widely used in automobiles is the automatic transmission technology that combines the hydraulic torque converter and the planetary gear train, but it has obvious disadvantages: the transmission ratio is discontinuous, the hydraulic transmission efficiency is low, and the structure is complicated. It is inconvenient to maintain, another continuously variable transmission (CVT), which uses a metal transmission belt and a variable diameter driving and driven wheel to transmit power, but the weakness of CVT is that the metal belt has a small carrying capacity, limited transmission power, and high cost The service life is short, and its control system is quite complex, resulting in an increase in auxiliary costs. Currently, it can only be used in cars
The invention is the first to create an interference planetary gear CVT made of a planetary gear interference mechanism, which can directly perform stepless variable torque and variable speed operation according to the load change during operation. The interference planetary gear CVT of the invention has never been seen at home and abroad Similar structural products and related information

The invention relates to an enginery transmission, in particular relates to an interference planet gear continuously variable transmission to transform the torsion by a planet gear interference mechanism in a transmission system. The vital parts of the interference planet gear continuously variable transmission comprises an input shaft, a left wheel input, a right wheel input, a left planet gear, a right planet gear, a left lateral wheel shaft, a right lateral wheel stand, a right lateral wheel shaft, a left gear ring, a right gear ring, an output panel, an output shaft, an advancing clutch, a reverse gear clutch, and a body, Through the operation of two sets of planet gears to generate interference, torsion is transferred by skid force generated by an advancing clutch, further moment of torque is transformed, thus when maximum torque is output, maximum speed of revolution can be output when load decreases, therefore mechanical continuously variable transmission function is finished reliably, thus the structure is simple,price is low,transmission ratio continuous bearing capacity is large,safe and reliable service life is long.
