The electro hydraulic thruster is composed of two parts, a drive motor and a body (centrifugal pump). The body part is composed of a cover, a cylinder, a piston, an impeller and a shaft.
When energized, the motor drives the transmission shaft and the impeller on the rotating shaft to rotate, generating pressure in the piston. Under the influence of this pressure, oil is sucked from the upper part of the piston to the lower part of the piston, forcing the piston and the push rod and beam fixed on it to rise rapidly. The load spring is mechanically compressed by the lever (the pusher or brake has a load spring) to produce mechanical movement.
When the power is cut off, the impeller stops rotating, and the piston quickly descends under the load of the spring force and its own gravity, forcing the oil to flow into the upper part of the piston again, and at this time it is still restored to its original position through the lever mechanism.
The electro hydraulic thruster is often used in conjunction with the brake rack, and is widely used in the braking of various transmission devices.
