Device, C2 clutch, C4 brake, C5 brake, which are realized, retreats III gear；A part of power is through transmission input shaft, gear pair, change
Amount pump (4), variable displacement motor (5) are input to the sun gear (10) of P2 planet row, another part power through transmission input shaft, C1 from
Clutch is input to P1 planet row, then is output to the gear ring of P2 planet row with the speed ratio of 1:1 by P1 planet row, and two parts power passes through
The planet carrier (11) of P2 planet row collaborates, and slows down and is output to the sun gear (15) of P3 planet row, then the tooth successively through P3 planet row
Enclose (14) output gear (17), end gear (18) transmitting is exported by the output shaft (19) of end gear (18).
10. mechanical-hydraulic according to any one of claim 1 to 9 mixes stepless transfer gear box, it is characterised in that: institute
State variable pump be can positive and negative rotation hydraulic pump, the variable displacement motor be can positive and negative rotation hydraulic motor.
