Description
Technical field
The present invention relates to Automotive Steering Technology field, especially relate to a kind of energy-absorbing motor steering column assembly.
Background technology
In the time of automobile generation head-on crash, the collision of automobile and obstacle is called initial collision.After the collision of automobile and obstacle, because the wait for bus collision of interior object of inertia occupant and bearing circle, Windshield is called secondary collision.
The energy of initial collision makes automotive front generation plastic deformation, and the motion backward under the effect of impact force of the fore tween drive shaft being connected with steering gear input shaft is installed simultaneously.Secondary collision: when initial collision automotive front generation plastic deformation, impact force acts on steering shaft lower end, and tubing string is moved backward, chaufeur originally rushes at bearing circle under the effect of collision force of inertia simultaneously.
In order to guarantee that chaufeur has the portion of energy of enough living spaces and absorption secondary collision, requires steering column to have crumple energy-absorbing function.
But existing steering column can only sub-fraction crumple, and energy-absorbing effect is not good, easily drops to chaufeur thigh top after steering column crumple, cause energy-absorbing to lose efficacy or collision again, and bearing circle can hinder chaufeur to escape in vehicle with steering column whereabouts.
Summary of the invention
For prior art deficiency, technical matters to be solved by this invention is to provide a kind of energy-absorbing motor steering column assembly, and it prevents from falling after steering column crumple.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of energy-absorbing motor steering column assembly, comprise upper and lower mandrel and upper and lower column jecket and regulate support, described upper mandrel is located in column jecket, and described lower mandrel is located in lower column jecket, and described upper column jecket is connected with lower column jecket, described upper column jecket is located at and regulates on support, also comprise the installation bracket for being connected with vehicle body, between described installation bracket and adjusting support, chute coordinates, and is fixedly connected with by injection moulding pin simultaneously.
Further, on described adjusting support, be provided with groove along upper prop tube axis direction, described installation bracket is provided with the projection suitable with groove.
Described groove and the projection portion of matching are provided with hole, and described injection moulding pin is located in hole.
Interference fit between described upper column jecket and lower column jecket.
Between described upper mandrel and upper column jecket, lower mandrel and lower column jecket, be all connected by nylon coated or injection moulding spline.
Described lower mandrel lower end is connected with the tween drive shaft of Telescopic sliding.
Described installation bracket is provided with rotary sleeve, and described rotary sleeve comprises binding bolt and the clamping band for fixing column jecket, and clamping band open end and installation bracket are provided with corresponding hole, and binding bolt is through the fixing column jecket in hole.
On described binding bolt, cover has sleeve.
The present invention compared with prior art, has the following advantages:
1, installation bracket provides the reliable radial support of total travel to steering column by chute, prevents from falling after steering column crumple, and then reduces the injury of bearing circle to chaufeur and enough spaces of escaping are provided;
2, steering column can total travel in along the even energy-absorbing of steering column axis, energy-absorbing effect is good, reduces the injury values of steering swivel system to human body;
3, angle of steering tubular column adjustment structure is simple, convenient operation;
4, relatively former steering column, simple in structure, is convenient to manufacture, and reduces costs.

In figure: 10. go up column jecket on mandrel, 11. times mandrels, 20., 21. times column jeckets, 30. regulate supports, 40. installation brackets, 50. rotary sleeves, 51. sleeves, 52. linings, 53. nuts, 54. binding bolts, 55. clamping banies, 60. injection moulding pins, 70. tween drive shafts.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 to 4, this energy-absorbing motor steering column assembly, comprises mandrel 10, lower mandrel 11, upper column jecket 20, lower column jecket 21, tween drive shaft 70, regulates support 30 and the large parts of installation bracket more than 40.
Interference fit between upper column jecket 20 and lower column jecket 21, can adjust by changing the magnitude of interference between the two the energy-absorbing size of column jecket.Between upper mandrel 10 and upper column jecket 20, lower mandrel 11 and lower column jecket 21, all can be connected by nylon coated or injection moulding spline, can relative sliding when crumple, there is the steering column of reduction crumple peak force, improve energy-absorbing effect, and the effect that alleviates noise.Lower mandrel 11 lower ends are connected with the tween drive shaft 70 of Telescopic sliding, improve crumple energy-absorbing effect.Said structure make whole steering column can total travel in along the even energy-absorbing of steering column axis, energy-absorbing effect is good, reduces impact, thereby reduces the injury values of steering swivel system to human body.
Regulate on support 30 and be provided with groove along upper prop tube axis direction, installation bracket 40 is provided with the projection suitable with groove.Or installation bracket is provided with groove, regulate support to be provided with the projection suitable with groove.Groove and the projection portion of matching are provided with hole, and injection moulding pin is located in hole, the optional nylon injection-molding pin of injection moulding pin.
Impact moment injection moulding pin 60 is cut off, and regulates support to slide together in company with upper column jecket, and the support providing by installation bracket can not be fallen steering column, guarantees the smooth crumple energy-absorbing of steering column.Adjust injection moulding pin shearing force size by diameter or the Shooting Technique parameter of adjusting injection moulding pin, injection moulding pin only provides tubing string crumple peak force.
When collision occurs, the power that human body acts on bearing circle passes to mandrel 10 on steering column, upper mandrel 10 passes to power upper column jecket 20 and regulates support 30, regulate injection moulding pin 60 fracture in shears between support 30 and installation bracket 40, after this regulate between support 30 and installation bracket 40 relative motion occurs, installation bracket 40 is by regulating support 30 to provide support upwards to tubing string, in assurance, column jecket 20 is along the chute direction even energy-absorbing of slip smoothly, thereby stable absorption the portion of energy in car load when collision, alleviate the injury that collision rear steering tubing string causes chaufeur.When slidably tween drive shaft 70 can absorb collision simultaneously, front deck part intrusion amount, guarantees the smooth crumple of tubing string.
Steering column assembly of the present invention reaches steering swivel system:
When vehicle under nominal situation carries out head-on crash with the speed of 48.3Km/h-53.1Km/h, be less than 127mm along the amount of movement backward of certain point that not affected by collision;
In vertically measured steering column for vehicle car relative to steering shaft top, be not subject to the amount of moving up of colliding certain point affecting to be less than 127mm;
When body block is clashed into steering apparatus with the relative velocity of 24.1Km/h-25.3km/h, the horizontal force that steering apparatus acts on body block is less than 11123N.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
