FIELD: transport mechanical engineering; infinitely variable transmissions for transport facilities. SUBSTANCE: proposed adjustable hydro-mechanical transmission includes input shaft 1 and output shaft 9 for connection with engine 11 and with propulsor 10 of transport facility, hydraulic pump 2 and hydraulic motor 7 and differential mechanism 7. Fitted on shaft 1 is rotor of reversible variable-capacity hydraulic pump 2 and crown gear wheel 6 is rigidly secured on rotor of non-adjustable reversible hydraulic motor 7 mounted on intermediate shaft 3. Ratio of sun gear wheel 4 of differential mechanism and rotor of hydraulic pump 2 is equal to 1. EFFECT: wide range of change of speeds of rotation of output shaft including change in sense of rotation. 2 cl, 2 dwg
