Abstract

The utility model relates to the field of automobile steering systems, in particular to a steering pipe column. The steering pipe column with a function of reducing the harm to a driver comprises a steering shaft, a guide cylinder, a skid shoe block, an upper bracket, a lower bracket and an adjusting handle, wherein the guide cylinder is sleeved on the steering shaft; the steering shaft can freely rotate in the axial direction relative to the guide cylinder; the adjusting handle is fixedly arranged on the upper bracket; the skid shoe block is pressed against the upper bracket through a mortise; one end of the upper bracket and one end of the lower bracket are fixedly arranged on the guide cylinder; the other end of the upper bracket is fixedly arranged on a vehicle body bracket through the skid shoe block; the other end of the lower bracket is fixedly arranged on the vehicle body bracket; the steering shaft is connected with a steering wheel. According to the steering pipe column, impact force which comes from the body of the driver and is applied to the steering wheel under the action of inertia is buffered, so that the protection effect of the steering pipe column on the driver during vehicle collision is greatly improved, the harm to the driver caused by a steering mechanism is reduced, and the steering pipe column plays an important role in protecting the driver.

Description

There is the steering column alleviating chaufeur injury function

Technical field

The utility model relates to automotive steering field, relates in particular to a kind of steering column.

Background technology

The radical function of steering column is to connect steering handwheel to deflector, and transmit the handling maneuver of steering handwheel, simultaneously, steering column is also as a safety component, in collision happens, chaufeur, can be to comprising that the steering hardware of bearing circle produces a very large impulsive force due to self very big effect of inertia forward, and this anti-force becomes a main source of causing chaufeur chest and head injury.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of steering column alleviating chaufeur injury function that has; impulsive force bearing circle being produced due to effect of inertia from chaufeur health by buffering; significantly increased the protective effect of steering column to chaufeur in collision happens; alleviate the injury of steering hardware to chaufeur, for improving, steering swivel system is significant to the protective effect of chaufeur.

The utility model is achieved in that a kind of steering column alleviating chaufeur injury function that has, comprise steering shaft, guide cylinder, piston shoes piece, upper bracket, lower bracket and regulating handle, described guide cylinder is sleeved on steering shaft, has the degree of freedom of axial rotation between steering shaft and guide cylinder; Described regulating handle is fixedly mounted on piston shoes piece described in upper bracket and is pressed on upper bracket by the fourth of the twelve Earthly Branches, described upper bracket and lower bracket one end are fixedly mounted on guide cylinder, the upper bracket other end is fixedly mounted on body support by piston shoes piece, the lower bracket other end is fixedly mounted on body support, and described steering shaft is connected with bearing circle.

Described lower bracket is the sheet stay bearing plate of a fold-line-shaped.

Described guide cylinder two ends are sleeved on outside steering shaft by two ball bearing of main shafts.

Described upper bracket and lower bracket are arranged on guide cylinder by being welded and fixed.

The utlity model has and alleviate the steering column of chaufeur injury function by collision happens; upper bracket piston shoes piece produces slip effect, lower bracket produces crumple effect; the impulsive force that buffering produces bearing circle due to effect of inertia from chaufeur health; significantly increased the protective effect of steering column to chaufeur in collision happens; alleviate the injury of steering hardware to chaufeur, for improving, steering swivel system is significant to the protective effect of chaufeur.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.

Embodiment 1

As shown in Figure 1,3, a kind of have a steering column alleviating chaufeur injury function, comprise steering shaft 1, guide cylinder 2, piston shoes piece 3, upper bracket 4, lower bracket 5 and regulating handle 6, described guide cylinder 2 two ends are sleeved on outside steering shaft 1 by two ball bearing of main shafts, have the degree of freedom of axial rotation between steering shaft 1 and guide cylinder 2; Described regulating handle 6 is fixedly mounted on piston shoes piece 3 described in upper bracket 4 and is pressed on upper bracket 4 by the fourth of the twelve Earthly Branches, described upper bracket 4 is arranged on guide cylinder 2 by being welded and fixed with lower bracket 5 one end, upper bracket 4 other ends are fixedly mounted on body support 7 by piston shoes piece 3, lower bracket 5 other ends are fixedly mounted on body support 7, and described steering shaft 1 is connected with bearing circle 8.

In the present embodiment, as shown in Figure 2, in order to make lower bracket 5 can produce crumple when colliding, the power of buffering to chaufeur, described lower bracket 5 is the sheet stay bearing plate of a fold-line-shaped.

When bumping, piston shoes piece 3 can be deviate from from upper bracket 4 after the impulsive force that is subject to bearing circle 8 to a certain extent, lower bracket 5 can produce structural distortion after the bearing circle impulsive force being subject to a certain extent, piston shoes piece 3 and lower bracket 5 bump at car load, bearing circle is subject to next same-action of situation of impulsive force, snubber part is from the impulsive force of bearing circle, thereby alleviate the injury of steering hardware to chaufeur, through test, show to have to alleviate and can from the impulsive force of greatest peak 3000N, just start to produce crumple effect to the steering column of chaufeur injury function, until piston shoes piece from upper bracket is thrown off, stable crumple power can be reduced to 1500 ± 500N, played the effect of protection chaufeur.
