The invention discloses a trailer rope assembly for an automobile. The trailer rope assembly for the automobile comprises a trailer rope, a cake-shaped shell, a rope twisting disk assembly used for winding an automobile pulling rope, and a driving mechanism. The rope twisting disk assembly is connected with the shell in the mode that the rope twisting disk assembly can rotate around the central axis through an annular limiting groove formed in the inner side wall of the shell. A driving disk is in transmission connection with a motor in the mode that the driving disk is fixed in the circumferential direction of a motor rotor and slides in the axial direction. A columnar spring is arranged between the driving disk and the motor and abuts against the driving disk so that the driving disk can drive the rope twisting disk assembly to rotate through friction force, and two rope passing holes which are symmetrical in the radial direction are formed in the side wall of the shell; the automobile pulling rope is straightened through sliding of the rope twisting disk assembly and the driving mechanism, a dynamic friction factor between the rope twisting disk assembly and the driving mechanism can be properly adjusted so that the rope twisting force of the automobile pulling rope can be proper, the rope winding speed is reasonably controlled, the structure is simple, the shell and the rope twisting disk assembly are made of light high-strength plastics, the overall weight is low, operation is safe and convenient, and the trailer rope assembly for the automobile is convenient to popularize.
