机电作动器(EBA)组件是全电刹车区别于电液、液压刹车的重要部件,其作用是将控制器输出的控制电信号直接转化成刹车压力,是全电刹车中最重要的一个能量转化模块。机电作动器由无刷直流电动机、减速齿轮组、滚珠丝杠组件和机架组成,控制电信号直接输送到无刷直流电机的驱动控制器中,控制电机的转速和转向,通过减速齿轮系带动螺母转动,从而带动滚珠丝杠轴向直线移动,对刹车组件施加压力或释放压力,最终对刹车力矩进行调整控制。 Electromechanical Actuator (EBA) components are all electric brake different from the electro-hydraulic brake, hydraulic brake important role, its role is to control the output signal of the controller directly into brake pressure, is the most important electric brake in a whole energy Conversion module. Electromechanical actuator consists of a brushless DC motor, a reduction gear set, a ball screw assembly and a frame. The control electrical signal is directly transmitted to a brushless DC motor drive controller to control the rotation speed and direction of the motor. The reduction gear train Drive the nut to rotate, so as to drive the ball screw to move linearly in the axial direction, exert pressure on the brake assembly or release the pressure, and finally adjust and control the brake torque.
