Abstract
The utility model discloses a steering column for an automobile, which comprises a steering shaft, a steering sleeve, an upper support frame and a lower support frame. A bearing is arranged in the steering sleeve to support the steering shaft; the upper support frame and the lower support frame are fixed on a cross beam of an automobile body; and the lower support frame is made of deformable materials. During the collision process of automobiles, chests of drivers are protected against damage by utilizing the outside force applied to the steering column; and the collapsing is generated while energies are absorbed and collided to ensure that the chests of the drivers can not be further damaged by the backward movement of a steering wheel. The collapsing and the energy absorption of the steering pipe column can be achieved by utilizing expectant deformation of the lower support frame without the disconnectable steering shaft and the steering sleeve. The utility model has the advantages of simple structure, low cost, safety and reliability.
Description
Technical field
The utility model relates to a kind of steering column for vehicles with shrinkable collision energy-absorbing performance.Be particularly related to a kind of simple in structure, cost is low, reliability is high steering column for vehicles.
Background technology
Steering gear is being born transmission chaufeur input direction dish direction information in the cruising process, the wheel steering system work effect that input requires is provided, simultaneously when collision happens, constituted the car load passive safety system of occupant restraint with car load safety restraint system such as safety strap, safety air bags, to guarantee when the collision happens and will drop to bottom line to the injury that chaufeur and occupant are subjected to.
Usually the Steering gear that has conquassation formula energy-absorbing function, it comprises changes upward axis, turn to lower shaft, turn to upper bush, turn to lower sleeve, metal (upper, contain the upper bracket that can break away from briquetting and fixing lower bracket.Change upward axis, lower shaft and turn to upper and lower sleeve to connect by a definite form, this type of attachment disconnects under specific conquassation power effect, turn to lower shaft and turn to sleeve generation slide relative up and down,, absorb the energy of collision along moving away from the direction of chaufeur.Simultaneously, slide relative can take place in the briquetting of upper bracket on support when being subjected to greater than specific conquassation power, guarantees that steering column can slide the energy that absorption portion collision simultaneously produces along the direction away from chaufeur.The steering shaft of conventional steering post and sleeve are formed by separable upper and lower two parts, the collapse energy-absorption system by three groups totally six parts constitute complex structure.This Steering gear causes certain influence because complex structure causes the global tolerance scope bigger to car load collision passive security performance matched accuracy.
Therefore, need a kind of simple in structure, service-strong crumple formula collision energy-absorbing steering column to realize the accurately purpose of coupling of car load collision safety performance.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, service-strong crumple formula collision energy-absorbing Steering gear, realizes the accurately purpose of coupling of car load collision safety performance.
To achieve these goals, steering column for vehicles of the present utility model comprises steering shaft, turns to sleeve, upper bracket and lower bracket, bearing is located to turn to and supports steering shaft in the sleeve, and upper bracket and lower bracket are fixed on the vehicle body crossbeam, and described lower bracket is made by deformable material.
Optimal way, described steering shaft and sleeve all are one of the forming.
Optimal way, deformable material are SPCE (deep-draws with cold rolling carbon steel thin plate and steel band).
Optimal way, described lower bracket yield strength is 230-355Mpa.
Optimal way is provided with briquetting in the described upper bracket, and upper bracket is connected with the vehicle body crossbeam by described briquetting.
Optimal way, described briquetting is connected with upper bracket by riveting or injection moulding mode.
Steering gear of the present utility model utilizes the upper and lower support combined action of Steering gear in the vehicle collision process, crumple takes place when absorbing collision energy, guarantees that the chaufeur chest can not cause further injury because of moving behind the bearing circle.
The utility model utilizes the expection distortion of lower bracket, need not the steering shaft of breakaway-element and turns to sleeve, can realize the crumple and the energy absorbing of Steering gear, and is simple in structure, with low cost, safe and reliable.
Description of drawings
Below, will be described in further detail the specific embodiment of the present utility model in conjunction with the accompanying drawings, wherein:
Fig. 1 is the Steering gear scheme drawing of a kind of embodiment of the utility model;
Fig. 2 is the utility model upper bracket scheme drawing;
Fundamental diagram when Fig. 3 is Fig. 2 crumple;
Fundamental diagram when Fig. 4 is the utility model lower bracket crumple energy-absorbing.
The specific embodiment
See also Fig. 1, the Steering gear of a kind of embodiment of the utility model comprises steering shaft 1, head bearing 2, turns to sleeve 3, upper bracket 4, lower bearing 5 and lower bracket 6.Upper and lower bearing 2,5 is located to turn to and is used for supporting steering shaft 1 in the sleeve 3, and the moment of torsion of steering shaft 1 direction of transfer dish input is to tween drive shaft and steering box.
With reference to Fig. 1, steering shaft 1 and sleeve 3 all are one of the forming, and are provided with a steering shaft 1 in a sleeve 3, and steering shaft 1 and sleeve 3 all are integral types.This is different from the employing sectional type steering shaft of prior art and turns to sleeve, and the steering shaft of Steering gear and sleeve are formed by separable upper and lower two parts.The utility model adopts such design, makes Steering gear simple in structure, realizes the crumple function better.Certainly, Steering gear of the present utility model also can adopt sectional type or other similar structures.
As shown in Figure 2, the fundamental diagram the during crumple of Steering gear upper bracket, upper bracket 4 is fixed on the vehicle body crossbeam by vehicle body crossbeam weld bolt 7 and nut 8, and briquetting 12 is fixed on the upper bracket 4 by certain mode, as riveting, injection moulding etc.When collision happens, Steering gear is subjected to external impacts, and when the suffered axial force of Steering gear during greater than a certain setting value, briquetting 12 relative upper brackets 4 slide, and Steering gear is to slide away from the direction of chaufeur (seeing arrow A direction shown in Figure 3).Owing to be fastened on vehicle body crossbeam 9 by nut 8, briquetting 12 breaks away from steering column upper bracket 4 the most at last and stays on the vehicle body crossbeam 9.In the process that above-mentioned Steering gear slides, the energy part of collision is absorbed.
Shown in 4, the fundamental diagram during lower bracket crumple energy-absorbing, lower bracket 6 is fixed on the body support 11 by bolt 10.When collision happens, Steering gear is subjected to external impacts, Steering gear lower bracket 6 moves downward under the effect of trend at impulsive force that is collided and Steering gear, and lower bracket deforms, thereby drives Steering gear to slide away from the direction of chaufeur (seeing arrow A direction shown in Figure 4).Crumple and energy absorbing that lower bracket deforms and just can realize Steering gear, in specific design, can preestablish the deformation locus of lower bracket, the design-calculated track depends on the requirement of car load, fundamental principle is that to keep Steering gear to prolong axis direction in the conquassation process descending, and the lower bracket distortion is not interfered with peripheral part, avoids conquassation normally to carry out.Distortion by lower bracket makes Steering gear further to the direction motion away from chaufeur, and further absorbs the energy of collision.
In sum, the disclosed Steering gear of the utility model need not the steering shaft of breakaway-element and turns to sleeve, can realize the crumple and the energy absorbing of Steering gear, and is simple in structure, with low cost, safe and reliable.
