Abstract

The invention discloses a double-motor driving device for a disc-type electro-mechanical brake. The double-motor driving device comprises a planetary gear mechanism 3, a main motor 1, an auxiliary motor 5, a main motor clutch 2, auxiliary motor clutches 4, a lead screw nut mechanism 6 and a speed sensor, wherein the main motor 1 and the auxiliary motor 5 are arranged on the two sides of three planetary gears 32 of the planetary gear mechanism 3 correspondingly, and an output shaft of the main motor 1 and an inner rotor 52 of the auxiliary motor 5 are both connected with the three planetary gears 32; the main motor clutch 2 is arranged between the main motor 1 and the planetary gears 32; the auxiliary motor clutches 4 are arranged between the auxiliary motor 5 and the three planetary gears 32; a lead screw 61 of the lead screw nut mechanism 6 is connected with a sun wheel 33 of the planetary gear mechanism 3, a nut 62 of the lead screw nut mechanism 6 is in threaded connection with the lead screw 61, and the nut 62 is attached to a movable braking block of the disc-type electro-mechanical brake; and the speed sensor is arranged between the main motor clutch 2 and the planetary gears 32. Through the double-motor driving device, the braking reliability of the disc-type electro-mechanical brake is improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a dual-motor drive device and a drive method for a disc electromechanical brake. Background technique [0002] Electromechanical brakes driven by a single motor often cause brake failure due to unsprung shock, vibration and high temperature during braking, and cannot continue to provide braking force. The invention patent publication number is CN106523551 A, and the name is a dual-motor brake actuator for automobile decoupling distributed braking system. It discloses a scheme of using a regenerative motor and a stepping motor for braking, but this scheme combines the regenerative motor and the The actuators are arranged side by side, which doubles the space occupied by the braking system. The dual motor output is used for different working conditions. Although the recovery of braking energy is increased, the improvement of the reliability of the braking system is v...
