Abstract
The utility model relates to the field of automobile component parts, in particular to a steering column safety protection mechanism. A steering column collapsing, guiding and energy absorbing mechanism comprises a fixed bracket, a sliding bracket and a buffer mechanism, wherein the fixed bracket is fixedly arranged on an automobile body, the sliding bracket is fixedly arranged on a column, and the fixed bracket is connected with the sliding bracket by the buffer mechanism. The steering column collapsing, guiding and energy absorbing mechanism has the advantages that through the friction force between a friction plate and the fixed bracket, on the premise of not greatly increasing the cost of component parts, the three effects of collapsing, guiding and energy absorbing of the steering column are realized, meanwhile the energy absorbing capability can be easily adjusted through the adjustment of clamping force of a bolt, and the target value of the impact energy absorbing is set, so the energy absorbing capability of the steering column can be effectively realized, the expected effect of energy absorbing during automobile collision is ensured, the injury to drivers by the automobile collision is minimized, and the safety of passengers is well ensured.
Description
Technical field
The utility model relates to the auto parts and components field, relates in particular to a kind of steering column safety protective mechanisms.
Background technology
Steering column is the critical component of running car system, ensures the critical component of chaufeur life security when being vehicle collision again simultaneously; Turn to tubing string in the prior art mostly directly and bearing circle connect firmly, during collision happens, the chaufeur head is because secondary collision hits bearing circle, the steering column that connects firmly with bearing circle is subject to the impact of chaufeur head, for want of crumple guiding energy absorber, cause steering column crumple energy-absorbing effect barely satisfactory, can not bring into play the energy absorption ability of tubing string fully, so that steering hardware can not play good crash protection effect to chaufeur; Although be provided with crumple guiding energy absorber on some steering column, this type of mechanism is very complicated, with high costs, weight is heavier, this has not only affected the handling of vehicle, also can cause adverse influence to vehicle performance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of steering column crumple guiding energy absorber, by the friction force between friction lining and the fixed support, under the prerequisite that increases not significantly the parts cost, triple effects of the crumple of realization steering column, guiding, energy-absorbing.
The utility model is achieved in that a kind of steering column crumple guiding energy absorber, comprise fixed support, sliding support and buffer gear, described fixed support is fixedly mounted on the vehicle body, described sliding support is fixedly mounted on the tubing string, links to each other by buffer gear between described fixed support and the sliding support.
Described buffer gear comprises lower friction lining, upper friction plate, orienting lug and pretension bolt, offer guide groove on the described fixed support, in the described guide groove orienting lug is set, the friction face of described lower friction lining and upper friction plate is close to support bracket fastened inside and outside two sides, and described pretension bolt passes fixed support, sliding support and orienting lug and clamps lower friction lining and upper friction plate.
Offer a pair of symmetrical guide groove on the described fixed support, left orienting lug and right orienting lug are set respectively in a pair of guide groove, left bolt passes left orienting lug and clamps lower friction lining and upper friction plate, and right bolt passes right orienting lug and clamps lower friction lining and upper friction plate.
The utility model steering column crumple guiding energy absorber is by the friction force between friction lining and the fixed support, under the prerequisite that increases not significantly the parts cost, realize the crumple of steering column, guiding, triple effects of energy-absorbing, can realize comparatively easily simultaneously the adjusting of energy-absorbing power by the gripping power of adjusting bolt, set the expected value of absorbing impact energy, can effectively bring into play the energy absorption ability of steering column, guarantee that the vehicle collision energy-absorbing gets a desired effect, vehicle collision is dropped to minimum to the injury of chaufeur, reach the purpose that guarantees well occupant safety.
Description of drawings
Fig. 1 is the utility model steering column crumple guiding energy absorber perspective view;
Fig. 2 is that the utility model steering column crumple guiding energy absorber master looks schematic cross-section.
Among the figure: 1 fixed support, 2 sliding supports, 3 times friction linings, 4 left orienting lugs, 5 left bolts, 6 right bolts, 7 right orienting lugs, 8 friction linings, 9 steering columns.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, 2, a kind of steering column crumple guiding energy absorber, comprise fixed support 1, sliding support 2 and buffer gear, described fixed support 1 is fixedly mounted on the vehicle body, described sliding support 2 is fixedly mounted on the steering column 9, links to each other by buffer gear between described fixed support 1 and the sliding support 2.
In the present embodiment, described buffer gear comprises lower friction lining 3, upper friction plate 8, orienting lug and pretension bolt, offer guide groove on the described fixed support 1, in the described guide groove orienting lug is set, the friction face of described lower friction lining 3 and upper friction plate 8 is close to the inside and outside two sides of fixed support 1, and described pretension bolt passes fixed support 1, sliding support 2 and orienting lug and clamps lower friction lining 3 and upper friction plate 8.
In order to improve the effect of energy-absorbing, offer a pair of symmetrical guide groove on the described fixed support 1, left orienting lug 4 and right orienting lug 7 are set respectively in a pair of guide groove, left bolt 5 passes left orienting lug 4 and clamps lower friction lining 3 and upper friction plate 8, and right bolt 6 passes right orienting lug 7 and clamps lower friction lining 3 and upper friction plate 8.
During installation, by the gripping power of adjusting bolt, steering column collision energy-absorbing power is adjusted to target call.When collision happens, the chaufeur head is because secondary collision hits bearing circle, the steering column that connects firmly with bearing circle is subject to the impact of chaufeur head, steering column crumple guiding energy absorber of the present utility model is had an effect, the sliding support 2 that connects firmly with steering column 9 moves down under the impact effect, orienting lug, lower friction lining 3 and upper friction plate 8 move down together under the drive of bolt, overcome the friction force between upper and lower friction lining and the fixed support 1 in the process that moves down, thereby realize that energy-absorbing power is even, the collision crumple energy-absorbing effect that the crumple direction is controlled.
