    • A rack drive assembly adapted for use in a vehicle electric power steering assembly includes a bearing assembly disposed in a rack housing and carried by a ball nut assembly for rotatably supporting the ball nut assembly relative to a steering member; and a spanner nut carried by the rack housing for securing the bearing assembly in the rack housing. A first isolator, a second isolator and a first shim are provided wherein the first isolator is disposed between an inner surface of the housing and a first surface of an outer race of the bearing, the second isolator is disposed between an opposite second surface of the outer race of said bearing and the first shim, the first shim is disposed between the second isolator and the spanner nut. The first shim is provided with a member configured to be coupled to the housing to allow for axial movement but prevent rotational motion of the shim during installation of the spanner nut.
    • 适用于车辆电动助力转向组件的齿条驱动组件包括:轴承组件,其设置在齿条壳体中并由滚珠螺母组件承载,用于相对于转向构件可旋转地支撑滚珠螺母组件; 以及由齿条壳体承载的扳手螺母,用于将轴承组件固定在齿条壳体中。 提供了第一隔离器,第二隔离器和第一垫片,其中第一隔离器设置在壳体的内表面和轴承的外座圈的第一表面之间,第二隔离器设置在第二隔离件的相对的第二表面之间 所述轴承的外圈和第一垫片,第一垫片设置在第二隔离器和扳手螺母之间。 第一垫片设置有构造成联接到壳体以允许轴向移动但是在安装扳手螺母期间防止垫片的旋转运动的构件。

    • A rack drive assembly adapted for use in a vehicle electric power steering assembly includes a ball nut assembly having at least a first end portion and an opposite second end portion, a bearing assembly carried by the ball nut assembly for rotatably supporting the ball nut assembly, a pulley assembly configured to be carried by the ball nut assembly, and at least a first spanner nut configured to be carried by the first end portion of the ball nut for securing the bearing assembly on the ball nut assembly. The ball nut includes a flange provided on an outer portion thereof configured to connect the ball nut to a pulley of a pulley assembly for rotation therewith. The flange is spaced remote from an end of the second end portion of the ball nut.
    • 适用于车辆电动助力转向组件的齿条驱动组件包括具有至少第一端部和相对的第二端部的滚珠螺母组件,由滚珠螺母组件承载的用于可旋转地支撑滚珠螺母组件的轴承组件, 构造成由滚珠螺母组件承载的滑轮组件,以及构造成由滚珠螺母的第一端部承载的至少第一扳手螺母,用于将轴承组件固定在滚珠螺母组件上。 滚珠螺母包括设置在其外部部分上的凸缘,其构造成将滚珠螺母连接到滑轮组件的滑轮以与其一起旋转。 凸缘远离滚珠螺母的第二端部的端部。
