The steering tube assembly comprises an inner tube and an outer tube, the outer tube is arranged on the outer side of the inner tube in a sleeving mode, the inner tube is used for assembling a steering shaft, a sliding groove extending in the axial direction of the inner tube is formed in the outer circumferential face of the inner tube, a roller is arranged on the inner circumferential face of the outer tube, and the roller is arranged in the sliding groove in a matched mode and abuts against the inner wall of the sliding groove. According to the steering tube assembly, radial gap adjustment and circumferential gap adjustment of the inner tube can be achieved at the same time through cooperation of the rollers and the sliding grooves, the number of parts is reduced while the steering shaft is stably adjusted, the structure is simple, the layout efficiency is high, and due to rolling friction between the rollers and the sliding grooves, the service life is prolonged. When the inner pipe stretches out and draws back in the outer pipe to achieve the angle and height adjusting function of the steering shaft, the friction force of the contact face is small, elements are not prone to abrasion, the requirement for the power of a motor is low, and cost is reduced.

    本发明公开了一种转向管组件、转向柱总成和车辆,所述转向管组件包括内管和外管,外管套设在内管外侧,内管用于装配转向轴,内管的外周面上设有沿其轴向延伸的滑槽,外管的内周面上设有滚子,滚子配合在滑槽内并抵紧滑槽的内壁。本发明的转向管组件利用滚子与滑槽的配合可同时实现对内管的径向间隙调节和周向间隙调节,保证转向轴调节稳定的同时,减少了零部件数量,结构简单,布局效率高,且由于滚子与滑槽之间为滚动摩擦,则内管在外管中伸缩以实现转向轴的角度、高度调节功能时,接触面摩擦力小,元件不易磨损且对电机的功率要求低,降低了成本。
