FIELD: transport engineering.
SUBSTANCE: invention is related in particular to stands with a hydraulic power circuit for testing transmissions of traction vehicles. The device contains a drive balancing electric machine, adjustable hydraulic pumps, kinematically connected with matching gearboxes, with which the output shafts of the tested transmission are kinematically connected, a transfer box, the input shaft of which is kinematically connected to the input shaft of the tested transmission, and the output shafts are kinematically connected to the adjustable hydraulic motors, pressure lines adjustable hydraulic pumps and adjustable hydraulic motors are looped. It also contains hydraulic loaders with a rotating spool driven by DC electric motors, in the body of which stacked disks with through holes made in them are installed, while the inlet pipes of the hydraulic loaders with a rotating spool are connected to pressure lines, and the outlet pipes are connected to a drain.
EFFECT: increasing the reliability of the results of bench tests of transmissions of traction vehicles.
