Embodiment Construction
[0064] As mentioned above, the locking force of the existing adjustable steering column in the locked state is too small, resulting in low reliability of the locking of the steering column.
[0065] In order to solve the above problems, the present invention provides an improved adjustable steering column. By rotating the first adjusting member in two opposite directions, the adjustable steering column can be switched between the locked state and the released state. When the first adjusting member is rotated in the first direction, the second adjusting member is pushed by the first adjusting member to move in a direction away from the first adjusting member, so that the adjustable steering column is in a locked state. When the adjustable steering column is locked, the first adjusting member, the second adjusting member, the first friction plate, the clamping arm of the mounting bracket, the fixing bracket, and the limiting member abut together along the axial direction of the supp...

The invention relates to a vehicle, a steering system of the vehicle, and an adjustable steering column of the vehicle. The adjustable steering column comprises a mounting support, an upper column tube and a locking and releasing control assembly, wherein the mounting support is used for being fixed to a vehicle body and is provided with clamping arms which are provided with first through holes; a fixing support is fixedly arranged on the outer wall of the upper column tube, used for being fixed to the clamping arms and provided with second through holes; the locking and releasing control assembly comprises a supporting rod penetrating through the first through holes and the second through holes, first adjusting pieces, second adjusting pieces, first friction pieces and limiting pieces, and the supporting rod is sequentially sleeved with the first adjusting pieces, the second adjusting pieces, the first friction pieces and the limiting pieces in the axial direction; the first adjusting pieces are fixed to the supporting rod, the supporting rod is sleeved with the second adjusting pieces and the first friction pieces in a spaced mode, the first friction pieces are provided with third through holes where the supporting rod can penetrate, and the limiting pieces are static relative to the supporting rod in the axial direction; and the clamping arms and the fixing support are oppositely arranged in the axial direction and located between the first friction pieces and the limiting pieces in the axial direction. Locking force of the adjustable steering column in the locked state is increased, and locking reliability of the steering column is improved.
Description
Technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and its steering system and an adjustable steering column. Background technique [0002] The steering column is one of the important devices of the vehicle steering system, and the steering wheel is installed on the steering column. In order to meet the individual needs of different drivers for the position of the steering wheel, most of the steering columns on vehicles use adjustable steering columns. The adjustable steering column can not only adjust the height of the steering wheel, but also adjust the angle of the steering wheel, that is, four-way adjustment can be achieved. [0003] The adjustable steering column is equipped with a locking and releasing control assembly. By rotating the handle in the locking and releasing control assembly in two opposite directions, the adjustable steering column can be in the locked state and the loosened state. Switch between. When ...
