Abstract
An energy sucking unit for the steering column of car is composed of a steering column, a mandrel linked with said steering column, and the lower and upper supporters arranged on the external shell of steering column. Said lower supporter can axially slide along the steering column in resistance varying mode. It can sufficiently suck the impact energy generated by collision.
Description
Technical field
The present invention relates to a kind of Endoenergic equipment of steering column of car.
Background technology
Usually, vehicle generally adopts the Steering gear structure that tilting is arranged.Bump in the process of assembling in the automobile front, Steering gear is along the energy of longitudinal direction of car, normally with impact loading in the driver.Therefore, insufficient by crumple mode Steering gear to energy absorbing, only account for the seldom part of impact energy.In addition, adopt the Steering gear tilt layout usually, after bumping, the steering support holder is opened, and can not keep the relatively stable of steering wheel position.Thereby, cause air bag also unstable to the position and the form of driver's expansion.
Summary of the invention:
Technical matters to be solved by this invention is, bump in the process of assembling at vehicle, because the Steering gear that adopts tilting to arrange, the impact energy of adorning that causes crashing absorbs not enough, cause the unsettled technical matters of bearing circle and balloon positions in addition, and a kind of Endoenergic equipment of steering column of car is provided.
Design of the present invention is, a kind of Endoenergic equipment of steering column of car is provided, and comprises Steering gear, with Steering gear bonded assembly axle core and be arranged in lower bracket and upper bracket on the Steering gear body skin, can do to become endwisely slipping of resistance along Steering gear at described lower bracket;
Between described Steering gear and lower bracket, be provided with outstanding ear, between outstanding ear and the Steering gear for captiveing joint;
Outside portion at described outstanding ear is provided with chute;
On the direction at center, the line of rabbet joint spacing of described chute is descending from the end of described Steering gear;
The cross-sectional plane of described lower bracket is " U " shape;
Described lower bracket is provided with pin, and described lower bracket is connected with chute by pin;
Described pin can make to become resistance exercise along the direction of chute;
Comprise a Support bracket on the described lower bracket, described Support bracket is provided with an outshot, and this outshot guiding lower bracket is made axial motion on Steering gear.
Adopt technical scheme of the present invention, can effectively solve at vehicle and bump in the process of assembling, impact energy absorbs not enough, causes the unsettled technical matters of bearing circle and balloon positions in addition, can reach the energy stabilization that puts on the driver when making collision, energy absorbing continues fully; Simultaneously, also have at the bottom of simple in structure, the cost, characteristics such as long service life.

The specific embodiment
A kind of Endoenergic equipment of steering column of car comprises Steering gear 2, with Steering gear 2 bonded assembly axle cores 1 and be arranged in lower bracket 5 and upper bracket 3 on Steering gear 2 body skiies, can do to become endwisely slipping of resistances along Steering gear 2 at described lower bracket 5; Between described Steering gear 2 and lower bracket 5, be provided with outstanding ear, between outstanding ear and the Steering gear 2 for captiveing joint; Be provided with chute 7 in the outside portion of described outstanding ear; On the direction at center, the line of rabbet joint 10 spacings of described chute 7 are descending from the end of described Steering gear 2; The cross-sectional plane of described lower bracket 5 is " U " shape; Described lower bracket 5 is provided with pin 6, and described lower bracket 5 is connected with chute 7 by pin 6; Described pin 6 can make to become resistance exercise along the direction of chute 7; Comprise a Support bracket on the described lower bracket 5, described Support bracket is provided with an outshot 8, and these outshot 8 guiding lower brackets 5 are made axial motion on Steering gear 2.
Described lower bracket 5 comprises a frame support bracket, and what this frame support bracket was fixing is installed on the car body.The frame support bracket bottom is around Steering gear 2, and with respect to pin 6 positions on the upper side, to guarantee still to keep Steering gear 2 axial locations after Steering gear 2 extends downwards; Pin 6: this pin 6 is connected and fixed Steering gear 2 Support brackets and Steering gear 2, and passes the support on the Steering gear 2, and axial slide 7 is arranged on this support, and can keep Steering gear 2 like this is that Steering gear 2 moves axially along chute 7, and guide groove is shaped as by wide gradual change narrow.Put on driver's energy stabilization when making collision.Energy absorbing continues fully.
Shown in Fig. 1-6, wherein Steering gear 2 is fixed on the car body by support and lower bracket 5.Upper bracket 3 is known, and it comprises: carriage, this carriage are fixed on the Steering gear 2; Mounting blocks 4, this mounting blocks 4 combines with carriage, and is fixed on the car body.
And the outshot 8 at lower bracket 5 rear portions is positioned at partially back (near the steering handwheel) part of pin 6 with respect to Steering gear 2, can center on the rotation of pin 6 when support is thrown off by the outshot 8 restriction Steering gears 2 of pin 6 chutes 7 and lower bracket 5.
During as Fig. 2, Fig. 3 vehicle frontal impact; with the application force of crossing the bearing circle transmission along Steering gear 2 axially apply impact load, support is deviate from along longitudinal direction of car from mounting blocks 4, pin 6 conquassation chutes 7 bore edges 11 enter the line of rabbet joint 10; and by the line of rabbet joint 10 guidings, Steering gear 2 moves before longitudinal direction of car.
At this moment, the outshot 8 of lower bracket 5 props up Steering gear 2, and Steering gear 2 is moved all the time vertically.Do not have the swing of above-below direction like this with regard to the position that guarantees bearing circle, can make the driver be subjected to the air bag better protect.
And, after entering chute 7, moves pin 6 along the line of rabbet joint 10, because the line of rabbet joint 10 sizes narrow down, and the intensity of chute 7 is very big, and this just is converted into the distortion of chute 7 with the impact load of Steering gear 2 and absorbs.
Should be known in that the present invention is not only limited to the foregoing description.For example when being arranged in Steering gear 2 and lower bracket 5 respectively, pin 66 and chute 77 also can obtain effect same as the previously described embodiments.
Adopt technical scheme of the present invention, can effectively solve at vehicle and bump in the process of assembling, impact energy absorbs not enough, causes the unsettled technical matters of bearing circle and balloon positions in addition, can reach the energy stabilization that puts on the driver when making collision, energy absorbing continues fully; Simultaneously, also have at the bottom of simple in structure, the cost, characteristics such as long service life.
