Technical Field

Background

When the piston hydraulic brake without the sealing ring is operated, a retarding effect is generated through a hydraulic retarder, and a certain braking force is generated by the internal stator through resistance generated by injecting liquid into the rotor.

Based on the above findings, the present inventors found that the conventional reciprocating sealless piston hydraulic brake mainly has the following disadvantages, for example:

when liquid is placed into the rotor, the rotor starts to operate in a certain direction, and due to the fact that the rotor is isolated without a sealing ring, the liquid is ground into a gap little by little in the operation process of the rotor, the subsequent rotating speed of the rotor is easily influenced, and even the rotor slips excessively.

It is therefore desirable to provide a reciprocating, seal-less piston hydraulic brake that prevents fluid from wearing into the seam.
