Abstract
The utility model provides a novel routed controllable steering drive axle structure of power that contracts relates to vehicle a steering system field, including axle core, axle sleeve, two V type briquettings, two interior hexagonal awl end holding screw, the axle core inserts in the axle sleeve, axle core bilateral symmetry is provided with V type slide, two V type briquettings set up respectively in two V type slides, the cooperation of V type briquetting and V type slide, V type briquetting is fixed at the axle sleeve inboardly through interior hexagonal awl end holding screw. The utility model provides a novel routed controllable steering drive axle structure of power that contracts can contract the force control with bursting within equitable scope, has solved and has burst the too big problem of difference that contracts, guarantees the uniformity of exemplar, can absorb the collision energy in addition within the stroke is contracted in whole ulcerate always, and it is more even that the force rate is contracted in whole process ulcerate, can prevent to burst to contract the power rapid change and lead to the fact driver's secondary damage.
Description
Technical field
The utility model relates to wheel steering system field, particularly relates to the steering inner articulated shaft structure that a kind of novel crumple power is controlled.
Background technology
In Collision test, weighing the degree of automobile to occupant injury is the important indicator judging vehicle safety performance, wherein how reducing steering hardware to the injury of chaufeur is again one of them important scoring item, if the impulsive force that the front end crash that effectively can not absorb steering column, steering inner articulated shaft transmits and actv. crumple, the as easy as rolling off a log injury caused chaufeur face, chest of steering hardware.So apply many crumple energy-absorbing technology in the steering system, reduce the injury of steering hardware to chaufeur.
Although steering column and the steering inner articulated shaft of current most of manned vehicle all have crumple endergonic structure, as nylon injection-molding break pin, interference fit energy-absorbing etc., but always there is various defect, as the impact of the Mismachining tolerance by injecting hole size during nylon injection-molding, injected plastics material, Shooting Technique, often the shear strength difference of part and part is larger, and nylon injection-molding pin is once after cutting off, crumple power can sharply decline, and can not continue crumple energy-absorbing; And for example elastic conjunction energy absorber is often also because the reasons such as Mismachining tolerance make crumple power differ larger, often tolerance variations is ± 0.05 time, just can produce the crumple power of 1000N change, for the such safety component of steering swivel system, this is defective for this, if by means of only the working accuracy improving part, this can increase again the manufacturing cost of part undoubtedly, has great significance so design so a kind of crumple power controollable steering inner articulated shaft structure.
Utility model content
The purpose of this utility model is the steering inner articulated shaft structure providing a kind of novel crumple power controlled, to solve the problems of the technologies described above, this steering inner articulated shaft crumple power can control, owing to can control the pressing-in force of axle core and axle sleeve during fabrication, so the crumple power of transmission shaft well can be controlled, ensure the collision crumple energy absorption ability of automobile.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The steering inner articulated shaft structure that a kind of novel crumple power is controlled, it is characterized in that: comprise axle core, axle sleeve, two V-type briquettings, two interior hexagonal cone end holding screws, described axle core inserts in axle sleeve, described axle core bilateral symmetry is provided with V-type slideway, two described V-type briquettings are separately positioned in two V-type slideways, V-type briquetting coordinates with V-type slideway, and described V-type briquetting is fixed on inside axle sleeve by interior hexagonal cone end holding screw.
Described interior hexagonal cone end holding screw screws in inside axle sleeve outside axle sleeve, and is tightened on sleeve lining by V-type briquetting, regulates the screw-down torque of holding screw can change the friction force of V-type briquetting and axle core.
Described sleeve diameter is greater than the external diameter of axle core, has mobile space during such axle core in axial direction crumple.
In transmission shaft manufacturing process, regulate holding screw that pressing-in force initial value is set, judging it when axle core press-in axle sleeve whether within the claimed range of design by detecting the size of pressing-in force, if there is deviation, by the screw-down torque of adjustment holding screw, pressing-in force being adjusted in scope of design.
The beneficial effects of the utility model are:
The utility model provides the controlled steering inner articulated shaft structure of a kind of novel crumple power, crumple power can be controlled within rational scope, solve part and part crumple difference problems of too, ensure the conformability of exemplar, and collision energy can be absorbed within whole crumple stroke always, whole process crumple force rate is comparatively even, can prevent crumple power from sharply changing the secondary injury causing chaufeur.

Fig. 1 is schematic diagram of the present utility model
Fig. 2 is the partial enlarged drawing at I place in Fig. 1;
Fig. 3 is that A-A is to cutaway view.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
As Figure 1-3, the steering inner articulated shaft structure that a kind of novel crumple power is controlled, comprise axle core 4, axle sleeve 1, two V-type briquettings 2, two interior hexagonal cone end holding screw 3, axle core 4 inserts in axle sleeve 1, axle core 4 bilateral symmetry is provided with V-type slideway, two V-type briquettings 2 are separately positioned in two V-type slideways, and V-type briquetting coordinates with V-type slideway, and V-type briquetting 2 is fixed on inside axle sleeve 1 by interior hexagonal cone end holding screw 3.
When transmission shaft receives axial crumple power, axle core 4 can in axial direction be pressed in axle sleeve, now two V-type briquettings 2 can slide in the V-type slideway of axle core 4, the length of whole transmission shaft can shorten, and absorb the ability of colliding and producing by the friction force of V-type briquetting 2 and V-type slideway, avoid rigid construction to driver like this.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets is only preference of the present utility model; be not used for limiting the utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
