Kinetic force is transferred to the second input shaft to drive the second input shaft to be circumferentially rotated, and two grades of main teeth and the second input shaft are
Fixed connection structure, therefore when the second input shaft is circumferentially rotated, two grades of main teeth also can due to the rotation of the second input shaft into
Row circumferentially rotates, and two grades of main teeth will drive two grades and be circumferentially rotated from tooth, and two grades are set to jackshaft from tooth to be circumferentially fixed
On lateral wall, therefore power can be transmitted to the main main tooth of slowing down by jackshaft when being circumferentially rotated from tooth for two grades, and main deceleration
Power can be gone out to slow down from tooth progress power output by main tooth by speed changer again;To complete the first power input mechanism and the
Power coupling between two power input mechanisms.
Embodiment 3: when the speed changer of the technical program is needed gear from when fading to one grade for two grades, first motor can be reduced
Torque, the second motor will increase torque, when the torque of first motor is reduced to 0, the gearshift mechanism of the first output shaft lateral wall
It hangs to neutral gear, adjusts the revolving speed of first motor at this time, until the revolving speed of first motor is consistent with the revolving speed of one grade of main tooth, change at this time
The tooth set of mark structure can be sequentially connected with one grade of main tooth, to realize the speed changer from two grades to one grade of gear shift
Journey.
