A steering column assembly and handwheel actuator assembly for steer-by-wire of a vehicle, the steering column assembly including: a shroud having a first shroud portion and a second shroud portion; a shaft supported by one or more bearing assemblies; and a linear actuator comprising an elongate threaded rod connected to one of the shroud portions by a first bracket assembly at a first position and to the other shroud portion by a second bracket assembly at a second position, the linear actuator controls the telescopic position of the shroud by rotating the threaded rod about the axis of the threaded rod, characterized in that at least one of the bracket assemblies is adapted to provide a degree of lost motion between the linear actuator and the associated shroud portion, the lost motion accommodates misalignment of the two shroud portions during use of the steering column assembly, which would otherwise apply a bending moment to the linear actuator.
一种用于车辆的线控转向的转向柱组件和手轮致动器组件,该转向柱组件包括:护罩,该护罩具有第一护罩部分和第二护罩部分;轴,该轴由一个或多个轴承组件支撑;以及线性致动器,该线性致动器包括长形螺纹杆,该长形螺纹杆在第一位置处通过第一支架组件连接至这些护罩部分中的一个护罩部分并且在第二位置处通过第二支架组件连接至另一个护罩部分,该线性致动器通过使螺纹杆围绕螺纹杆的轴线旋转来控制护罩的伸缩位置,其特征在于,这些支架组件中的至少一个支架组件被适配用于在线性致动器与相关联的护罩部分之间提供一定程度的空动,该空动在转向柱组件使用期间适应这两个护罩部分的未对准,否则该未对准会向线性致动器施加弯矩。
