Multi-range transmission performance deriving method for range alternating switch, involves adjusting coupling and variator within synchronizing point range such that moment of motor and revolution of radar maintain constant progression

摘要

The method involves coordinately adjusting a coupling and a variator within a range of a synchronizing point in such a manner that moment on a drive side or an output side of a motor as well as revolution of a radar maintain constant progression. The coupling is joined with a range alternating switch. A parabola function is used as a control function for a variator transmission during a range change.
