Electro-Mechanical Brake Apparatus Whose Mounting Surfaces Cooperate for Cabling and Vehicle

An electro-mechanical brake apparatus includes a housing of a driver and a housing of a brake, the housing of the driver and the housing of the brake each include a mounting surface, the two mounting surfaces are fastened to each other, each mounting surface includes a through hole, the through hole is configured to avoid a transmission connecting member. At least one mounting surface includes at least one groove, the at least one groove is configured to avoid at least one signal transmission line, and the at least one signal transmission line is electrically connected to a circuit component accommodated in at least one of the housing of the driver or the housing of the brake. A gap between the mounting surfaces of the housings facilitates layout of the signal transmission line.
