Collapsible steering column assembly
摘要:
A steering column assembly includes an upper jacket and a lower jacket partially disposed within said upper jacket. A bushing is disposed between the upper jacket and the lower jacket. The upper jacket and the lower jacket are collapsible along a longitudinal axis in response to a collision event. A first roller mechanism and a second roller mechanism are mounted to the upper jacket near a forward end and a rearward end of the bushing respectively for engaging the lower jacket in rolling engagement. The first and second roller mechanisms resist a resultant force caused by a bending moment created by a transverse load applied to a distal end of the upper jacket to minimize an increase in a sliding frictional force between the bushing and the lower jacket.
