FIELD: machine engineering.
SUBSTANCE: hydraulic cylinder for traction testing of machines consists of a hydraulic system which includes a double-acting hydraulic cylinder comprising a cylinder and a piston with a rod, a device for controlling the hydraulic cylinder and hoses. The hydraulic cylinder additionally contains a hydraulic line with sequential arrangement of a quadrangular adapter thereon, a return valve and a gauge. The hudraulic line is air-tightly connected to the cylinder rod cavity. The control valve is connected in parallel with the return valve and connects the gauge cavity with the cylinder rod cavity. The hydraulic cylinder control unit is made in the form of a two-way control valve which is connected with the piston cylinder cavity on one side, and on the other one is connected through the quadrangular adapter with the rod cavity of this cylinder. A pressure sensor configured to transmit a signal to a computer is installed in the free end of the quadrangular adapter.
EFFECT: simplification of the hydraulic cylinder design for traction testing.
