Title:
ELECTRO-MECHANICAL BRAKING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/246136
Kind Code:
A1
Abstract:
Provided in the present invention is an electro-mechanical braking mechanism, relating to the technical field of braking structures, and comprising: an electric motor, a harmonic reducing mechanism and a push rod mechanism. The electric motor comprises an electric motor housing, and a rotor, a stator and a rotating shaft which are sequentially arranged in the electric motor housing from outside to inside, the rotor is fixedly connected to the rotating shaft, an end of the rotating shaft is rotatably connected to a rear end cover of the electric motor housing around the axis of the rotating shaft, the harmonic reducing mechanism is also arranged in the electric motor housing, the rotating shaft on a side of the rotor facing away from the rear end cover of the electric motor housing is inserted into a torque input end on a side of the harmonic reducing mechanism, to achieve transmission connection between the rotor and the harmonic reducing mechanism, the push rod mechanism is fixedly arranged on a torque output surface at the other side of the harmonic reducing mechanism, and the harmonic reducing mechanism is configured to drive the push rod mechanism to push a lever thrust arm of a brake caliper. The electro-mechanical braking mechanism disclosed in the present invention is oriented to the braking characteristics of commercial vehicles, and has the advantages of a large output rotating moment, a large axial bearing capacity, a high coupling degree between mechanisms, a compact overall layout and small space occupation.
