Zusammenfassung:FIELD: testing engineering. ^ SUBSTANCE: bench comprises driving shaft, hydraulic pump connected with the driving shaft, first and second hydraulic tanks, and first suction line whose inlet is connected with the first hydraulic tank and outlet is connected with the inlet of the hydraulic pump. The line has throttle and switch mounted upstream of the throttle. The switch connects the inlet of the line to the outlet of the hydraulic pump. The inlet of the second sucking line is connected with the second hydraulic tank. The bench also has the means for setting units to be tested and measuring instruments. The bench additionally has clutch for connection of the shaft of the hydraulic motor to be tested with the shaft of the axial-piston hydraulic pump, pickup of torque transmitted by the clutch, rigid frame for receiving the axial-piston hydraulic motor and axial-piston hydraulic pump, and pipelines for connecting the outputs of the axial-piston hydraulic pump and output of the axial-pump hydraulic motor to the switching device. The outlet of the second suction line is used for connecting the axial-piston hydraulic pump. The second hydraulic tank is in communication with the first hydraulic tank through the overflow pipeline whose inlet is connected with the second hydraulic tank and is mounted above the first hydraulic tank as well as the inlet and outlet of the second suction line. The outlet of the pressure-drain line is connected with the second hydraulic tank. The switching device is made of a T-branch to pride selected connection of the outputs of the hydraulic pump and axial-piston hydraulic motor to the throttle of the pressure-drain line. ^ EFFECT: expanded functional capabilities. ^ 2 cl, 1 dwg
