The invention relates to the technical field of brake-by-wire systems, in particular to an electronic mechanical brake structure for a brake-by-wire system. The caliper body is mounted on the bracket; the transmission mechanism is located in the support and comprises a driving shaft and a ball screw, one end of the driving shaft is arranged in the ball screw and rotationally connected with the ball screw, the outer wall face of the end, located in the ball screw, of the driving shaft and the inner wall face of the ball screw form a containing cavity, and an elastic assembly for driving the ball screw to move towards the driving shaft is arranged in the containing cavity; according to the invention, the driving shaft is matched with the ball screw, the driving shaft rotates to transmit torque to the ball screw, and the ball screw is pushed towards the driving shaft through the matching of the elastic element and the gasket, so that the ball screw and the driving shaft are matched more tightly, and the axial clearance of the ball screw is eliminated, thereby realizing more precise control.
本发明涉及线控制动系统技术领域,具体涉及一种用于线控制动系统的电子机械制动器结构,包括:支架;卡钳体,安装在支架上;传动机构,位于支架内,传动机构包括驱动轴和滚珠丝杠,驱动轴一端设置在滚珠丝杠内并与滚珠丝杠旋转连接,驱动轴位于滚珠丝杠内一端的外壁面与滚珠丝杠的内壁面形成容纳腔,容纳腔内设有驱动滚珠丝杠向驱动轴移动的弹性组件,本发明中,驱动轴与滚珠丝杠相配合,驱动轴转动将扭矩传给滚珠丝杠,并通过弹性元件和垫圈的配合,将滚珠丝杠向驱动轴的方向推动,使两者配合更紧密,消除滚珠丝杠的轴向间隙,从而实现更精密的控制。
