CN200920204204.1 is disclosed using planetary gear train form two-shift automatic speed variator, and its transmission moment of torsion is relatively low, but to gear
Manufacture level require it is very high therefore expensive, there is presently no widely used.
As Chinese patent CN201120028042.8 and CN201320028583.X are disclosed using synchronizer to two gear teeth
Wheel set carries out selection selection so as to carry out gear shift operation, and requirement of this structure for motor is higher, it is necessary to using low rotation
Inertia, high-precision motor, once because synchronizer successfully can not be coupled with power shift gear very much, then it is easy to burn out motor.And
And the problem of longitudinal size is bigger than normal also be present in the structure, because being the flat of spacing between differential assembly and motor output shaft
Row is set, and so mechanism arrangement for compact type type electric automobile causes very big puzzlement.
