The presence of part, then the rotational motion of rotary shaft 3 is transferred to selector fork 8 by link assembly, i.e. drive selector fork is around support shaft 9
Rotation, the shifting block of selector fork 7 push speed changer shifting block to move along a straight line and complete gear shifting action.Selector fork is parallel to groove 82
Side wall side on there is reversed column 84, which is arranged in the guide groove 73 of sensor shift fork 7；When selector fork is around branch
When supportting the rotation of axis 9, the rotation of sensor shift fork will drive, the rotation of sensor shift fork can generate an angular displacement, so that angular displacement
Sensor 6 generates numerical value change.To complete the angle position that the swing offset conversion of shift can be read for angular displacement sensor 6
Numerical value is moved, it can be by the angular displacement numerical value of transmission calibration detected to angular displacement numerical value when keeping off with the angular displacement sensor 6
Comparison result, to determine whether shift in place.Two gears mechanical transmission provided by the invention is applied to pure electric vehicle power
Electrical vehicular power and economy can be improved in system and hybrid power system, reduces the requirement to driving motor performance, makes to drive
Dynamic motor more works in high efficient area, extends its continual mileage.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
