As shown in Figure 1:
Electrical generator 5 is arranged on the flywheel of driving engine 1 (does not have power-transfer clutch).
Driving engine 1 is connected with input shaft 15 through electrical generator 5, front propeller shaft 13.Its rotary motion is transferred to rear propeller shaft 17 by transmission output shaft 16 and is transferred to drive axle 19 through Parking Brake 18 again and drives car load to move after numerical control stepless change-speed box 14 speed change.

1=1.
In time travelling needs because of us and change transmission speed ratio, related physical quantity sensor flows to ECU (Electrical Control Unit) 10 digital electric signal, through ECU (Electrical Control Unit) 10 computing, exports control signal and controls its running to servomotor 11.Servomotor 11 drives the synchronized rotation of worm screw 12, and 27, the worm gear engaged with worm screw 12 rotates with the rotating speed more much lower than servomotor 11, inputs internally toothed annulus 21 then rotation synchronized with worm gear 27.Now the sun wheel of output planetary row 23 then obtains an additional rotating speed, the at this moment no longer synchronized rotation of the sun wheel of two planet rows because inputting the rotation of internally toothed annulus 21, and speed ratio is no longer 1.When the additional rotating speed that the sun wheel of output planetary row 23 obtains because of the rotation of input internally toothed annulus 21 is identical with the sun wheel hand of rotation of input planet row 22, output planetary arranges the rotating speed of the sun wheel of 23 by the rotating speed of the sun wheel higher than input planet row 22, i.e. n
2> n
1, be also the transmission speed ratio i=n of numerical control stepless change-speed box 14
2/ n
1> 1.When the additional rotating speed that the sun wheel of output planetary row 23 obtains because of the rotation of input internally toothed annulus 21 is contrary with the sun wheel hand of rotation of input planet row 22, output planetary arranges the rotating speed of the sun wheel of 23 by the rotating speed of the sun wheel lower than input planet row 22, i.e. n
2﹤ n
1, be also the transmission speed ratio i=n of numerical control stepless change-speed box 14
2/ n
1﹤ 1.And along with the increase of servomotor 11 rotating speed, the rotating speed n of the sun wheel of output planetary row
2reduce until be 0 gradually.Also be the transmission speed ratio i=0 of numerical control stepless change-speed box 14.Along with servomotor 11 rotating speed increases again, the sun wheel reversion of arranging causing output planetary, i.e. n
2﹤ 0, the transmission speed ratio i=n of numerical control stepless change-speed box 14
2/ n
1﹤ 0.Also namely the hand of rotation of the sun wheel of output planetary row is contrary with the sun wheel hand of rotation of input planet row.
In sum, as long as control the rotating speed of servomotor 11, the transmission speed ratio i that can make numerical control stepless change-speed box 14 is 1, is 0, for just, is negative.Stepless change.
Carry out now the principle of work of the automobile-used numerical control stepless variable ratio drive system of analytic explanation again.
