An electrically driven rack-and-pinion steering system (10) of a motor vehicle has: an axially displaceable mounted rack (14) which transmits steering movement to steered wheels of the motor vehicle; an electric drive (20) providing a steering force and interacting with the rack (14); and a housing (12) that receives the rack (14) and a drive element (22) of the drive (20), the drive element (22) engaging with a toothing system (16) of the rack (14). According to the invention, a bearing assembly (30) is arranged on a section (18) of the rack (14) without the toothing system, axially on each side of the drive element (22), having a carrier cylinder (31), on the outer shell surface (42) of which an outer contact seal (44) is arranged and on the inner shell surface of which an inner contact seal (40) is arranged, the contact seals (40, 40 ') being in contact with the outer contact seal (44) and the inner contact seal (40) being in contact with the inner contact seal (40, 40'). 44) seal the housing (12) with respect to the rack (14).

    一种机动车辆的电驱动的齿条小齿轮式转向系统(10)具有:可轴向移位地安装的齿条(14),该齿条为机动车辆的转向车轮传递转向运动;电驱动器(20),该驱动器提供转向力并且与齿条(14)相互作用;以及壳体(12),该壳体接纳齿条(14)以及驱动器(20)的驱动元件(22),驱动元件(22)与齿条(14)的齿部系统(16)接合。支承组件(30)布置在齿条(14)的没有齿部系统的区段(18)上、在轴向上布置在驱动元件(22)的每一侧,该支承组件具有承载筒体(31),在该承载筒体的外壳面(42)上布置有外接触密封件(44),并且在该承载筒体的内壳面上布置有内接触密封件(40),接触密封件(40,44)相对于齿条(14)密封壳体(12)。
