Utility model content
But, when being configured to be restricted the movement of steering column respectively in the left and right sides of steering column, if do not accomplish well during fabrication, the power at left and right sides usable uniform carrys out the words of moving-limiting, the load that then can cause steering column is departed from from stationary state, namely to depart from load different from each other in the left and right sides of steering column, steering column there will be torsion, thus worries that departing from load uprises a little and stably cannot obtain intentional disengaging load.
The utility model provides a kind of steering hardware 1, and it has: the steering shaft 2 transmitting steering-wheel effort; Tubing string 3 in rotatably supporting described steering shaft 2; Can rotatably to the outer tubing string 5 of the aluminum alloy that described steering shaft 2 supports, itself and described interior tubing string 3, vertically, can be fitted together to relatively movably, and are provided with and described interior tubing string 3 can be done fastening clamping section 10; With the body side bracket 6 that it fixes by the described clamping section 10 of clamping on vehicle body; And fastening device, it is according to the operation of user, described body side bracket 6 and described clamping section 10 are carried out fastening, fix described interior tubing string 3 and described outer tubing string 5 thus, and by carrying out the operation removed it, can implement the adjustment of bearing circle on its direction of tilt and telescopic direction, and it is characterized in that having:
With described clamping section and the described body side bracket together fastened friction plate 24b by described fastening device; With
Be embedded in outward on described interior tubing string 3, and the circle ring part 20 be combined with described friction plate 24b,
Described circle ring part 20 and described interior tubing string 3 are near the joint portion of described friction plate 24b and described circle ring part 20, be provided with the through hole 20a described circle ring part and described interior tubing string being done to run through, and combined by the pin 21 be inserted in this through hole 20a
Destroyed by after the impulsive force that specified when described pin 21, thus removed the combination of described circle ring part 20 and described interior tubing string 3.
Thereby, it is possible to obtain more stable and lower disengaging load.

Detailed description of the invention
Fig. 1 is the block diagram of the steering hardware 1 representing the utility model the 1st embodiment.When watching the Reference numeral of Fig. 1 from common reading direction, its facing to lower left side of Fig. 1 be by steering hardware 1 mounting vehicle time, for the side of rear view of vehicle side, and being when being installed on vehicle by steering hardware 1 facing to the upper right side of Fig. 1, is the side of vehicle front side.In FIG, about its hand of rotation centered by the central axis of steering hardware 1 towards, be then with by steering hardware 1, the state be mounted on vehicle is consistent.
As shown in FIG. 1 to 3, steering hardware 1 of the present utility model has: the steering shaft 2 transmitting steering-wheel effort; Tubing string 3 in rotatably supporting described steering shaft 2; Can rotatably to the outer tubing string 5 of the aluminum alloy that described steering shaft 2 supports, itself and described interior tubing string 3, vertically, can be fitted together to relatively movably, and are provided with and described interior tubing string 3 can be done fastening clamping section 10; With the body side bracket 6 that it fixes by the described clamping section 10 of clamping on vehicle body; And fastening device, it is according to the operation of user, described body side bracket 6 and described clamping section 10 are carried out fastening, fix described interior tubing string 3 and described outer tubing string 5 thus, and by carrying out the operation removed it, can implement the adjustment of bearing circle on its direction of tilt and telescopic direction.
Described steering hardware 1 also has: with described clamping section 10 and the described body side bracket 6 together fastened friction plate 24b by described fastening device; Be embedded in outward on described interior tubing string 3, and the circle ring part 20 be combined with described friction plate 24b.
Described circle ring part 20 and described interior tubing string 3 are near the joint portion of described friction plate 24b and described circle ring part 20, be provided with the through hole 20a described circle ring part and described interior tubing string being done to run through, and combined by the pin 21 be inserted in this through hole 20a, destroyed by after the impulsive force that specified when described pin 21, thus removed the combination of described circle ring part 20 and described interior tubing string 3.
And interior tubing string 3 does not carry out fastening by means of only the described clamping section on tubing string 5 outside, it is fixing that the circle ring part 20 also by being kept by inboard friction plate 23 and outboard friction plate 24a, 24b is implemented, thus firmly fixed.
According to steering hardware 1, usually will as described above, in it, tubing string is firmly fixed, but when a vehicle is in a collision, even if having when the passenger generation secondary collision that body weight is lighter, also can with stable, and lower impact load absorbs this impact.That is, interior tubing string 3 can not be made due to circle ring part 20 and outboard friction plate 24a, 24b to produce reverse, and shorten the total length of steering hardware 1, and then pin 21 is ruptured and disengaging occurs absorbs its impulsive force further.
In addition, according to the steering hardware 1 of the 1st embodiment, because pin 21 is arranged in circle ring part 20, near the bound fraction of strengthening part 8, so just can prevent when secondary collision, it produces moment of flexure on circle ring part 20, and can prevent the increase of the disengaging load caused because of moment of flexure.
In addition, according to the steering hardware 1 of the 1st embodiment, inboard friction plate 23 and outboard friction plate 24a, 24b will be integrally constituted by circle ring part 20, therefore, just can prevent the fastening force based on friction from occurring different phenomenons in left and right, thus prevent when secondary collision, make disengaging load raise because of the torsion of steering column.
In addition, according to the steering hardware 1 of the 1st embodiment, even if can realize a kind of after the impact absorbing secondary collision, steering column is also unlikely to the steering come off.
In addition, according to the steering hardware 1 of the 1st embodiment, interior tubing string 3 firmly fixes by strengthening part 8, and it can improve the antivibration rigidity of steering column, and can guarantee steering stability.
And the interior tubing string 5 of present embodiment is made as its blank by the steel of tubulose.Therefore, its good rigidly, and can effectively improve when when absorbing impact, discordant situation that interior tubing string 3 produces.In addition, also circle ring part 20 can be manufactured by aluminium diecasting alloy or synthetic resin.
