Abstract
The utility model relates to a steering column with a collision friction energy absorbing mechanism. A U-shaped bracket is sleeved on the middle part of a steering column body through a pin shaft; a mounting bracket is arranged outside the middle part of the U-shaped bracket through two rivets and is plate-like; the upper part of the mounting bracket corresponding to the axial direction of the U-shaped bracket is provided with two parallel sliding chutes; the two rivets are positioned in the two parallel sliding chutes on the mounting bracket respectively; and mounting holes are formed around the upper part of the mounting bracket outside the sliding chutes respectively. When a vehicle collides, and acting force on the steering column body exceeds a certain value, friction force formed by a friction plate, the mounting bracket and the rivets is overcome, so that the steering column body slides down along the mounting bracket to realize crimping friction energy absorption; meanwhile, the steering column body does not get off the mounting bracket of the steering column, so that other damages are not caused due to falling.
Description
Technical field
The utility model belongs to the automobile steering system technical field, is specifically related to a kind of steering column of automobile steering system.
Background technology
Aspect automotive crash safety property; For preventing the injury of steering swivel system to chaufeur; Steering column has played important effect therein; Absorbed the impulsive force of chaufeur head impact safety air bag through the feedback of the syllogic on the steering column energy absorber actv. that contracts, reduced in the car load collision process injury chaufeur.At present, the contract first of energy-absorbing of the syllogic of steering column feedback is generally attachment point and pulls the locking-type structure, and this structure steering column main body when collision pulls breaks away from two attachment points on instrument desk, and easy chest and knee to chaufeur damages.
Summary of the invention
In order to solve when collision pulls, the steering column main body has broken away from the attachment point on the instrument desk, the easy problem that the chest and the knee of chaufeur are damaged, and the utility model provides a kind of steering column with collision friction energy absorber that improves structure.
Concrete improvement technical scheme is following:
Steering column with collision friction energy absorber comprises the steering column body, and said steering column body middle part is provided with the U-shaped support through pin sleeve, and the U-shaped mid-stent outside is provided with mounting bracket through two rivets; Mounting bracket is tabular, is provided with two parallel chutes with the U-shaped support shaft to cooresponding mounting bracket top, and said two rivets lay respectively on the mounting bracket in two parallel chutes; Be respectively equipped with mounting hole around the mounting bracket top in the chute outside.
Be arranged with friction lining B on two rivets in the said mounting bracket outside, be set with friction lining A on two rivets between mounting bracket and the U-shaped support.
Outwards protrude the bottom of said mounting bracket, is provided with the indent strengthening groove in the middle part longitudinally along mounting bracket.
The useful technique effect of the utility model is: the steering column body, is promptly realized contracting along its axial direction feedback, simultaneously through force of sliding friction absorbing impact energy to lower slider along chute when collision.And this structure when collision the steering column main body do not break away from the mounting bracket on instrument desk, avoided damaging because of chest and knee that the tubing string body comes off to chaufeur.This kind version is simple, and reliability is high, and cost is low, is easy to property production in batches.

Fig. 2 is the exploded view of Fig. 1.
Fig. 3 for the back steering column body that bumps along chute landing constitution diagram.
Sequence number among the last figure: U-shaped support 1, friction lining A2, mounting bracket 3, chute 3.1, mounting hole 3.2, friction lining B4, rivet 5, steering column body 6.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1, the steering column with collision friction energy absorber comprises steering column body 6.U-shaped support 1 is equipped with through pin sleeve in steering column body 6 middle parts, and the outside, U-shaped support 1 middle part is provided with mounting bracket 3 through two rivets 5.Mounting bracket 3 is tabular, offers 3.1, two rivets 5 of two parallel chutes with the U-shaped support shaft to cooresponding mounting bracket 3 tops and lays respectively on the mounting bracket 3 in two parallel chutes 3.1; Offer mounting hole 3.2 around mounting bracket 3 tops in chute 3.1 outsides respectively.Referring to Fig. 2, be set with friction lining B4 on two rivets 5 in the mounting bracket outside, be set with friction lining A2 on two rivets 5 between mounting bracket 3 and the U-shaped support 1.Outwards protrude the bottom of mounting bracket 3, is provided with the indent strengthening groove in the middle part longitudinally along mounting bracket 3.
During use, mounting bracket 3 is installed on the instrument desk Guan Liang in the car through mounting hole 3.2 and bolt.Referring to Fig. 3; When collision happens; When the application force on the steering column body surpasses certain numerical value, overcome the friction force that friction lining A2, friction lining B4, mounting bracket 3, rivet 5 are constituted, make steering column body 6 realize the feedback friction energy-absorbing that contracts to lower slider along mounting bracket 3; The steering column main body does not break away from its mounting bracket 3 simultaneously, can not cause other injury because of dropping.
