The utility model is related to a kind of steering column for vehicles clamping structures, including column tube, c-type pipe is equipped on column tube, c-type pipe, which is externally connected to, encircles stent, it encircles and mounting bracket is installed on the outside of stent, encircle stent and be connected with lower mounting bracket close to one end of universal-joint fork, set lever passes through upper mounting bracket and encircles stent, it offers sliding slot on c-type pipe, sliding slot corresponding position is provided with spacer pin on column tube.The utility model has many advantages, such as that simple in structure, cost is relatively low, the convenient reliable, sliding force of production technology and crumple power are stablized, and can greatly improve that steering column is vertical and the rigidity and intrinsic frequency of horizontal direction, and actual frequency test value is in more than 52Hz.
Description
Technical field
The utility model patent is related to a kind of steering column for vehicles clamping structure, can effectively improve the folder of motor turning column stiffness
Locking structure.
Background technology
It is also more next for the intrinsic frequency requirement of steering column with continuous improvement of the automobile research for NVH performance requirements
Higher, traditional clamping structure is often difficult to reach requirement.The rigidity of steering column part in itself directly determines the height of its intrinsic frequency
It is low, to vehicle NVH performance guarantee important roles.
Utility model content
The purpose of this utility model is to provide a kind of steering column for vehicles clamping structure, has both slidable adjustment limiting and crumple is inhaled
It can function.
The purpose of this utility model is achieved through the following technical solutions：
A kind of steering column for vehicles clamping structure including column tube 1, is equipped with c-type pipe 8 on column tube 1, c-type pipe 8 is externally connected to
Stent 2 is encircled, the outside for encircling stent 2 is equipped with mounting bracket 4, encircles stent 2 and is connected close to one end of universal-joint fork
There is a lower mounting bracket 5, set lever 3 passes through upper mounting bracket 4 and encircles stent 2, offers sliding slot 7 on c-type pipe 8, on column tube 1
7 corresponding position of sliding slot is provided with spacer pin 6.
The beneficial effects of the utility model are as follows：
Encircling between stent and column tube for the utility model is designed using the encircling type of large access area, and when locking can compare
Steering column is relatively easily made to obtain higher rigidity；Simultaneously spacer pin design so that this structure have both slidable adjustment limiting and
The function of crumple energy-absorbing optimizes the overall structure of steering column.The utility model can greatly improve that steering column is vertical and transverse direction side
To rigidity and intrinsic frequency, actual frequency test value in more than 52Hz, the utility model have simple in structure, cost compared with
The advantages that low, the convenient reliable, sliding force of production technology and crumple power are stablized.

Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of the utility model；
Fig. 3 is the front view of the utility model；
Fig. 4 is the vertical view of the utility model；
Fig. 5 is the bottom view of the utility model.
Specific embodiment
The utility model is described in more detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, c-type pipe 8 is equipped on column tube 1 successively and encircles stent 2, c-type pipe 8 and stent 2 is encircled and uses
Aluminum alloy casting technique is non-occluded configuration, is designed with opening, ensures there is elasticity during stress；Stent 2 is encircled close to universal
One end of section fork is connected with lower mounting bracket 5, and the other end for encircling stent 2 is equipped with mounting bracket 4；Set lever 3 is worn
It crosses mounting bracket 4 and encircles stent 2, set lever locks pattern using cam bit, during locking, the metal plate in upper mounting bracket 4
Golden planar structure, which can clamp, encircles stent 2；It encircles on stent 2 and offers sliding slot 7, setting is limited in sliding slot corresponding position on column tube 1
Position pin 6, spacer pin 6 use nylon material, and interference is pressed in the pipe tap of column tube 1, and when adjusting steering wheel, spacer pin 6 can be
It is slided in sliding slot 7, plays position-limiting action；In collision process, this spacer pin, can be with column when steering wheel is by larger impact force
Pipe moves downwardly together, can be cut when reaching shear strength design limit, realizes crumple energy-absorbing.
Steering column is fixed on by upper mounting bracket 4, lower mounting bracket 5 on dashboard cross member.During routine use, lock
Tight handle 3 is locking state.Encircle in 2 structure of stent and be designed with opening, when set lever 3 is locked, encircle stent 2 because by
The coupling mechanism force effect of metal plate planar structure on to set lever 3 and upper mounting bracket, can generate small tightening deformation, thus
It encircles and larger stiction is generated between the inner wall of stent 2 and column tube 1.Because the contact area of locking is larger, so to turning to
The whole of column keeps rigidity to be promoted significantly.When driver needs to adjust the position of steering wheel, set lever 3 need to be opened, at this time
The stiction encircled between stent 2 and column tube 1 is released, and column tube 1 can be carried out axially in stent 2 is encircled
Slidable adjustment.Spacer pin 6 slides in sliding slot 7 during this, plays the role of adjusting limiting.Under limiting case, when automobile exists
When crashing, driver's body can act on an impact force in axial direction on column tube 1 by steering wheel.At this time
Handle is locking state, encircles stent 2 and is fixed on dashboard cross member by upper mounting bracket 4, lower mounting bracket 5, then solid
It is connected on vehicle body, in relatively motionless state.The slide downward under the action of impact force of column tube 1, overcome and encircle stent 2 it
Between stiction and spacer pin shear strength design limit, spacer pin 6 cut, and then realizes the crumple in collision process
Energy-absorbing.
