The invention discloses an electromagnetic type electronic mechanical brake. An output shaft of a motor is connected with an electromagnetic clutch through a speed reduction mechanism. The electromagnetic clutch is connected with a ball screw shaft. The ball screw shaft and a piston are arranged in a brake inlay body. The brake inlay body is provided with an inner cavity channel. The bottom surface of the inner cavity channel of the brake inlay body is provided with a center through hole. The outer side of the inner cavity channel extends out to be bent to form a clamp part. The inner end of the ball screw shaft extends out of the brake inlay body to be connected with the other end of the electromagnetic clutch. The outer end of the ball screw shaft is sleeved with a lead screw nut throughroll balls to form a lead screw nut pair. The inner end of the piston is connected to the bottom surface of the inner cavity channel of the brake inlay body through a return spring. The piston is sleeved with the inner cavity channel of the brake inlay body and moves along the inner cavity channel. The outer end of the piston is connected with a friction plate. The electromagnetic type electronicmechanical brake transmits and cuts off power through the electromagnetic clutch. There is no need to enable the motor to be rotated reversely and release power. The electromagnetic type electronic mechanical brake is quick in response, high in transmission efficiency and capable of reducing the brake release time and the service life of the motor is prolonged.
Description
technical field [0001] The invention relates to automobile brake technology, in particular to an electromagnetic electromechanical brake. Background technique [0002] With the rapid development of automobile intelligent technology, the application of automobile wire control technology in the whole vehicle is becoming more and more extensive. Electromechanical brake technology is a branch of brake-by-wire technology, and it is a brand-new vehicle brake concept. The electromechanical braking system has the advantages of simple structure, excellent performance, and environmental protection. The electromechanical brake is the actuator of the electromechanical braking system and is a key component for generating braking force. [0003] The electromagnetic clutch is a function of using electromagnetic energy to transmit the torque from the driving side to the driven side to complete the connection and power transmission of the transmission system. The electromagnetic clutch ha...
