    • Disclosed is a drive mechanism in which a movable bracket is operatively connected to a drive source so that the movable bracket is moved to a desired angular position, the movable bracket including an upper jacket supporting an upper shaft provided with a steering wheel attached thereto. One end of the movable bracket is pivotally supported by a fixed bracket attached to a vehicle, and the other free end of the movable bracket is pivoted on a nut member which engages a lead screw through an eccentric bearing assembly. The eccentric bearing assembly causes angular movement in the bracket as the nut member is linearly moved by rotation of the lead screw.
    • 公开了一种驱动机构,其中可移动支架可操作地连接到驱动源,使得可移动支架移动到期望的角度位置,可移动支架包括支撑设置有附接到其上的方向盘的上轴的上护套。 可移动支架的一端由固定在车辆上的固定支架枢转支承,可移动托架的另一个自由端在螺母构件上枢转,螺母构件通过偏心轴承组件接合导螺杆。 当螺母构件通过导螺杆的旋转线性移动时,偏心轴承组件引起支架中的角运动。
