(1) stepwise transmission:
Adopt gear drive, with a number of fixed transmission ratio. The gear transmission has the advantages of simple structure, easy manufacture, reliable operation and high transmission efficiency.
(2) Continuously variable transmission:
The transmission ratio can be continuously changed in a certain numerical range, and the conical belt drive is used to complete the power output.
(3) Integrated transmission:
It is a hydraulic mechanical transmission composed of a torque converter and a planetary gear transmission, whose transmission ratio can be stepless in the range of several discontinuities between the maximum and minimum value.
