Abstract
A retractable automobile steering column relates to the technical field of steering columns of steering wheels in automobile driving. The steering column comprises an upper steering column, an upper steering spindle, a lower steering column and a lower steering spindle, wherein the upper steering column is sleeved on the circumference of the upper steering spindle; the upper steering spindle is inserted into the lower steering spindle; and the lower steering column is sleeved on the circumference of the lower steering spindle. A plurality of positioning ring-shaped grooves are formed on the outer peripheral surface of the upper steering column perpendicular to the length direction of the upper steering column, correspondingly, positioning holes matched with the positioning ring-shaped grooves are formed on the inner peripheral surface of the lower steering column perpendicular to the length direction of the lower steering column; positioning steel balls are arranged in the positioning holes; and positioning springs are arranged between the positioning steel balls and the lower steering columns. The utility model has simple structure and good using effect, and reduces hurt to a driver caused by the steering wheel and the steering column in case of automobile collision, so as to protect the personnel safety of the driver.
Description
Technical field
The utility model relates to the technical field of the steering column of motor driving direction dish.
Background technology
According to statistics of traffic accidents data and the analysis showed that: during frontal crash of vehicles to the vehicle impact testing result, steering handwheel, rigidity steering column are the main elements that makes chaufeur injured, steering handwheel, rigidity steering column mainly are that the chest to chaufeur causes serious injury, and are the one of the main reasons that causes the chaufeur personal injury.How reducing steering handwheel, steering column causes to chaufeur personal injury to become an important topic of numerous scientific and technical personnel's researchs in automobile bumps process.Several improved steering hardwarees are arranged in the market, steering handwheel in the time of can alleviating automobile to a certain extent and bump, steering column are to the injury of chaufeur, the method that adopts mainly contains two kinds, a kind of is that steering column is divided into last two bodies down, between two bodies spring is housed up and down, the impulsive force that produces when relying on spring to absorb collision; Another kind be adopt the lower material of nylon pin, injection moulding pin equal strength to steering column, turn to axle to connect, when bump takes place, steering column, turn to axle generation crumple, thereby reduce injury chaufeur.Still there are very big impulsive force in these two kinds of methods bearing circle, steering column when auto against to the chaufeur health, so effect is unsatisfactory.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and result of use is good, and steering handwheel, steering column damaged the chaufeur person when reduction automobile bumped, the telescoping car steering tube column of protection chaufeur personal safety.
The utility model adopts following technical scheme for achieving the above object:
A kind of telescoping car steering tube column, comprise steering column, on turn to axle, down steering column, turn to axle down, last steering column is nested with the periphery that turns to axle last, on turn to axle to be plugged on down to turn in the axle, following steering column is nested with in the periphery that turns to axle down; Last steering column outer peripheral face perpendicular to last steering column length direction is provided with several steady ring connected in stars, cooresponding perpendicular to the following steering column inner peripheral surface setting and the knock hole that the steady ring connected in star mates of steering column length direction down, positioning ball is set on the knock hole.
Between positioning ball of the present utility model and the following steering column retainer spring is set.
Upper and lower steering column of the present utility model is realized highly location by detent mechanism, and the upper and lower axle that turns to also can realize axially freely stretching by the spline connection.A plurality of steady ring connected in stars are arranged on last steering column, in the steering column positioned internal hole retainer spring and lock ball are being installed down.The detent mechanism of being made up of steady ring connected in star, knock hole, retainer spring, lock ball can be realized the adjusting of steering column height and position.When the steering column height was regulated, the upper and lower axle that turns to was carried out synchronization telescope by spline.When automobile bumps, the impulsive force that steering column bears can make upper and lower steering column push lock ball in the steady ring connected in star open, together with bearing circle, to turn to axle to be punctured into rapidly the shortest, the height that turns to axle, steering column to shrink can guarantee that chaufeur has enough living spaces, thereby avoids the chaufeur chest is damaged.The utlity model has simple in structurely, result of use is good, and steering handwheel, steering column damage the effect of protection chaufeur personal safety when reducing automobile and bumping to the chaufeur person.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of telescoping car steering tube column, comprise steering column 4, on turn to axle 3, down steering column 1, turn to axle 2 down, last steering column 4 is nested with the periphery that turns to axle 3 last, on turn to axle 3 to be plugged on down to turn in the axle 2, following steering column 1 is nested with in the periphery that turns to axle 2 down; Last steering column 4 outer peripheral faces perpendicular to last steering column 4 length directions are provided with several steady ring connected in stars 5, cooresponding perpendicular to the following steering column 1 inner peripheral surface setting of following steering column 1 length direction and the knock hole 8 of steady ring connected in star 5 couplings, positioning ball 6 is set on the knock hole 8.
Between positioning ball 6 of the present utility model and the following steering column 1 retainer spring 7 is set.
Claims (2)
1. telescoping car steering tube column, comprise steering column (4), on turn to axle (3), down steering column (1), turn to axle (2) down, last steering column (4) is nested with the periphery that turns to axle (3) last, on turn to axle (3) to be plugged on down to turn in the axle (2), following steering column (1) is nested with in the periphery that turns to axle (2) down; It is characterized in that several steady ring connected in stars (5) being set perpendicular to last steering column (4) outer peripheral face of last steering column (4) length direction, cooresponding perpendicular to following steering column (1) the inner peripheral surface setting of following steering column (1) length direction and the knock hole (8) of steady ring connected in star (5) coupling, positioning ball (6) is set on the knock hole (8).
2. telescoping car steering tube column according to claim 1 is characterized in that between above-mentioned positioning ball (6) and the following steering column (1) retainer spring (7) being set.
