Background

The electric hydraulic driving unit consists of two parts, driving motor and body (centrifugal pump), and the body consists of cover, cylinder, piston, vane wheel and rotating shaft. When the motor is powered on, the motor drives the rotary shaft and the impeller on the rotary shaft to rotate, pressure is generated in the piston, and under the influence of the pressure, oil is sucked from the upper part of the piston to the lower part of the piston to force the piston, the push rod fixed on the piston and the cross beam to rise rapidly. The mechanical motion is generated by a lever mechanically compressing a load spring (with a pusher or brake loaded). When the power is cut off, the impeller stops rotating, the piston rapidly descends under the action of the load spring force and the gravity of the piston, oil is forced to flow into the upper part of the piston again, and the oil is still restored through the lever mechanism. The electric hydraulic thruster is often used in conjunction with a brake frame and is widely used for braking various transmission devices.
