Preferably, the end face above-mentioned screw element contacted with described lower bearing is flange face.
This utility model also provides for a kind of steering column, including lower bearing, column casing and mandrel, described lower axle Holding and be arranged in described column casing and fix, described mandrel is assemblied in described lower bearing, on described mandrel Boss face coordinates with the upper surface of the inner ring of described lower bearing, and described mandrel is for as described in above-mentioned any one Car steering tube column mandrel.
Preferably, above-mentioned steering column is car steering tube column.
The steering column mandrel that this utility model provides, including mandrel body, described mandrel body is used for The position blocking lower bearing is provided with external screw thread, described external screw thread is provided with for blocking described lower bearing The screw element of lower surface, described screw element offers with described external screw thread with the use of internal thread hole.
The steering column core shaft structure that this utility model provides by the fit structure of mandrel and lower bearing by jump ring Spacing, become screw element spacing.Lower bearing is installed in column casing and completes to fix, mandrel is assemblied in In lower bearing, the boss face on mandrel coordinates with the inner ring upper surface of lower bearing, and mandrel end cancels clamping The notch of jump ring, and then process the external screw thread coordinated with screw element, external thread length meets screw thread After part is urgent, the end face of screw element can compress lower bearing inner ring, is assembled on mandrel by screw element, beats Tight Tightening moment, the upper surface of such screw element coordinates with the inner ring lower surface of lower bearing, is finally completed down The assembling of bearing and mandrel is fixed.Overall structure is simple, it is simple to installing and manufacture, fastening effect is good, screw thread Part Tightening moment is adjustable, is not likely to produce abnormal sound such that it is able to avoid producing abnormal sound.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will The accompanying drawing used required in embodiment or description of the prior art is briefly described, it should be apparent that, Accompanying drawing in describing below is embodiments more of the present utility model, comes for those of ordinary skill in the art Say, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The structural representation of the steering column that Fig. 1 provides for this utility model embodiment;
Fig. 2 is the structural representation of steering column in prior art.
In figure 1 above-2:
Lower bearing 1, jump ring 2, mandrel body 3, screw element 4, column casing 5, draw-in groove 6, external screw thread 7.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with Accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear, It is fully described by, it is clear that described embodiment is a part of embodiment of this utility model rather than complete The embodiment in portion.Based on the embodiment in this utility model, those of ordinary skill in the art are not making The every other embodiment obtained under creative work premise, broadly falls into the scope of this utility model protection.
