REGULATION SYSTEM OF HYDROSTATIC TRANSMISSION Russian patent published in 2008 - IPC F16H61/46 B60T1/08 

FIELD: engineering industry; regulation system of hydrostatic transmission.

SUBSTANCE: hydrostatic transmission contains hydraulic pump (2), discharging the working medium to the first trunk line (5а) from the pump sideco or to the second trunk line (6а) from the pump side. Hydrostatic transmission also includes hydraulic engine (3), connected with the first trunk line (5b) from the engine side and with the second trunk line (5b) from the engine side (6b). The first trunk line (5а) from the pump side and the second trunk line (6а) from the trunk side could be combined relatively with the first trunk line (5b) from the engine side and with the second trunk line (6b) from the engine side through the brake valve unit (19). By means of brake valve unit (19) located lower along the hydraulic engine stream (3) first truck line (5b) from the engine side or second truck line (6b) from the engine side could be combined with the tank volume (12) by means of throttling depending on the operating pressure.

EFFECT: improving of hydrostatic transmission regulation system.
