Steering column for a motor vehicle

The invention relates to an electromechanical power steering system for a motor vehicle, comprising a worm shaft (13), which can be driven by an electric motor and which meshes with a worm wheel coupled to a steering shaft. The worm shaft (13) is rotatably mounted in a bearing (15), which has at least one bearing ring (16) mountable in a retainer (4), which can be moved relative to the worm wheel.In order to specify an electromechanical power steering system having an improved retainer, which has higher dimensional stability and increased stiffness, according to the invention, the retainer (4) has a main body (41) made of plastic, which main body is injection-molded onto the bearing ring (16) as an injection-molded part. 本发明涉及一种用于机动车辆的机电式动力转向系统，该动力转向系统包括蜗杆轴(13)，该蜗杆轴(13)可以由电动机驱动并且该蜗杆轴(13)与联接至转向轴的蜗轮啮合。蜗杆轴(13)以可旋转的方式安装在轴承(15)中，该轴承(15)具有能够安装在保持器(4)中的至少一个轴承套圈(16)，该保持器(4)可以相对于蜗轮移动。为了提出根据本发明的具有改进的保持器的机电式动力转向系统，该保持器具有更高的尺寸稳定性和增加的刚度，该保持器(4)具有由塑料制成的主体(41)，该主体(41)作为注射模制部件被注射模制到轴承套圈(16)上。
