The invention relates to an electromechanical brake pressure generator (1) having a spindle drive unit (2) for converting the rotational movement of a drive shaft (3) driven by an electric motor into the translational movement of a piston (4) coupled to the spindle drive unit (2), wherein the spindle drive unit (2) is operatively connected to the drive shaft (3) via a multi-stage transmission (5). According to the invention, the multi-stage transmission (5) is a planetary gear having a first and second stages (5.1, 5.2). A spindle (6) or a spindle nut (7) of the spindle drive unit (2) can be driven by means of the drive (5), which is rotatably mounted in a housing (9) of the brake pressure generator (1) by means of a bearing arrangement (8) that is subjected to axial and radial forces. The invention also relates to the brake system for a vehicle, comprising an electromechanical brake pressure generator (1) according to the invention.

    本发明涉及一种机电的制动压力发生器(1),其具有用于将以电动马达的方式驱动的驱动轴(3)的旋转运动转换成与主轴传动单元(2)耦合的活塞(4)的平移运动的主轴传动单元(2),其中,主轴传动单元(2)与驱动轴(3)经由多级的传动机构(5)作用连接。根据本发明,多级的传动机构(5)是具有第一级和第二级(5.1、5.2)的行星齿轮传动机构。借助传动机构(5)可驱动主轴传动单元(2)的主轴(6)或主轴螺母(7),其通过承受轴向力和径向力的轴承组件(8)可旋转地支承在制动压力发生器(1)的壳体(9)内。本发明还涉及一种用于车辆的制动系统,该制动系统具有根据本发明的机电的制动压力发生器(1)。
