Gear ratio, first controls the gear 3 rotating speed counterclockwise rotating speed counterclockwise higher than power shaft 1, i.e. higher than controlling in freewheel clutch
The rotating speed counterclockwise of circle 4, now controls one end little by being locked at wedge shape space for roller B24 of freewheel clutch, controls to surmount
Clutch generation locking, the first rotating speed counterclockwise controlling gear 3 cannot be than the rotating speed counterclockwise controlling freewheel clutch inner ring 4
Height, makes the rotating speed clockwise of the second control gear 14 decline, less than the rotating speed clockwise of a gear driven gear 19, i.e. less than roller
The rotating speed clockwise of retainer A20, now, controls friction plate 16 with controlling platen 15 and relative skidding can occur, produce counterclockwise
Frictional torque, this moment of torsion make roller rolling retainer 20 relative to one gear driven gear 19 turn over certain angle, roller counterclockwise
Roller A22 is stirred by retainer 20 to one end that wedge shape space is big, and roller A22 is maintained at one end that wedge shape space is bigger,
At this moment, one grade of freewheel clutch will not occur locking, and power is transferred to lamella clutch by second gear to mechanism completely,
Being delivered on output shaft 17, by decelerator driving gear 27, power exports the differential being integrated together with this change speed gear box again
Device, it is achieved vehicle reverses gear retrogressing.

Hour hands, a gear driven gear 19 rotates counterclockwise, and roller rolling retainer 20 rotates counterclockwise simultaneously.Roller rolling retainer 20 drives control again
Preparation of friction wafer 16 rotates, and controls platen 15 and the frictional force controlling to produce between friction plate 16 drove for the second control gear 14 inverse time
Pin rotates, and the second control gear 14 on output shaft 17 rotates counterclockwise the first control gear 3 on band driven input shaft 1, up time
Pin rotates, because controlling the gear ratio gear ratio more than first gear pair of gear pair mechanism, so now the first control gear 3
Rotating speed clockwise higher than the rotating speed clockwise of power shaft 1, i.e. higher than the control freewheel clutch inner ring being connected on power shaft 1
The rotating speed of 4.As it is shown in figure 5, when the first control gear 3 rotating speed clockwise is higher than controlling turning clockwise of freewheel clutch inner ring 4
During speed, roller B24 will not occur locking, controls freewheel clutch and does not transmit power.This time, automobile gearbox was operated in one
Gear pattern, controls gear pair mechanism and will not interfere with the power transmission of a gear.
During two gears, as same gear, as it is shown on figure 3, during two gears, power shaft 1 direction of rotation for turning clockwise, then exports
The direction of rotation of axle 17 is counterclockwise, and a gear driven gear 19 rotates counterclockwise, and roller rolling retainer 20 rotates counterclockwise simultaneously.Rolling
Post retainer 20 drives control friction plate 16 to rotate again, controls platen 15 and the frictional force controlling to produce between friction plate 16 drives
Second controls gear 14 rotates counterclockwise, and the second control gear 14 on output shaft 17 rotates counterclockwise on band driven input shaft 1
