An electromechanically drivable brake pressure generator for a hydraulic braking system of a vehicle, having at least one threaded drive assemblage for converting an input-drive-side rotary motion into a translational motion, and a piston/cylinder unit, actuatable by the threaded drive assemblage, for hydraulic brake pressure generation. The assemblage encompasses: a spindle that has a spindle thread; and a spindle nut that has a spindle nut thread, the spindle nut being disposed on the spindle thread of the spindle so that as one of the two spindle elements rotates, the other, which is prevented from twisting using a twist preventer, is axially displaceable. The spindle nut has a spindle nut body and at least one anti-friction layer made of plastic, which is applied on the spindle nut body and has a more pronounced anti-friction property than the spindle nut body, that anti-friction layer being applied on the spindle nut thread.

    本发明涉及一种用于车辆的液压制动系统的能够机电驱动的制动压力产生器,其具有至少一个用于将驱动侧的旋转运动转换成平移运动的螺纹传动组件和可由螺纹传动组件操纵的、用于液压地产生制动压力的活塞/缸单元。在此,螺纹传动组件包括具有主轴螺纹的主轴和具有主轴螺母螺纹的主轴螺母,其中,主轴螺母如此布置在主轴的主轴螺纹上,使得通过两个主轴元件之一的旋转可轴向移动另一个通过防扭转装置被固定以防扭转的主轴元件。在此,主轴螺母具有主轴螺母本体和至少一个施加在主轴螺母本体上的、由塑料制成的滑动层,该滑动层具有比主轴螺母本体更高的滑动特性,其中,该滑动层至少施加在主轴螺母螺纹上。
