On the other hand, the anti-lock braking device according to the embodiment of the present invention uses the structure of the components to simplify the combination relationship, and the pressure riveting technology can be used to achieve the required sealing performance without the use of welding, and to ensure that the components will not be operated at high speeds. Damage or breakage caused by vibration and high temperature. Furthermore, in the assembling method of the anti-lock braking device of the present invention, the oil return pump can be pre-assembled into three parts, which can reduce the process of assembling to the body, thereby improving the efficiency of assembly.

The present invention has been disclosed in preferred embodiments above, but those skilled in the art should understand that the above-mentioned embodiments are only used to describe the present invention and should not be construed as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the foregoing embodiments should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be defined by the scope of the patent application.
