The invention provides a brake actuator, a drive-by-wire mechanical electronic brake system and an automobile, and relates to the technical field of automobile brake control, the brake actuator comprises a shell, a motor, a motion conversion mechanism and a brake block, the motor, the motion conversion mechanism and the brake block are installed in the shell, a through installation cavity is formed in the motor, and a magnetic steel rotor of the motor is connected with a hollow shaft; the mounting cavity is positioned in the hollow shaft; an input shaft of the speed-reducing torque-increasing mechanism is connected with the hollow shaft so as to synchronously rotate with the hollow shaft, at least one part of the speed-reducing torque-increasing mechanism is fixedly connected with the shell, and at least the other part of the speed-reducing torque-increasing mechanism is located in the mounting cavity; the motion conversion mechanism is connected with an output shaft of the speed reducing and torque increasing mechanism and the brake block so as to convert the torque output by the speed reducing and torque increasing mechanism into thrust for pushing the brake block to move linearly. The electronic mechanical brake actuator solves the problems that an existing electronic mechanical brake actuator is bloated in structure and high in requirement for the size of an installation space.

    本发明提供了一种制动执行器、线控机械电子制动系统及汽车,涉及车辆制动控制的技术领域,包括:壳体,以及安装在壳体内的电机、运动转换机构和制动块,电机内部具有贯穿设置的安装腔,电机的磁钢转子连接有空心轴,安装腔位于空心轴内;减速增扭机构的输入轴与空心轴相连以与其同步旋转,减速增扭机构的至少一部分与壳体固定连接,减速增扭机构的至少另一部分位置于安装腔内;运动转换机构分别与减速增扭机构的输出轴和制动块相连,以将减速增扭机构输出的扭力转换为推动制动块线性运动的推力。本发明解决了现有电子机械制动执行器存在结构较为臃肿,对安装空间大小需求较高的问题。
