Abstract

The utility model discloses a safety steering shaft for an automobile steering wheel, which is composed of short shafts, short shaft sleeves, a spring group, a flexible pipe, a directional deformer, etc. An upper short shaft is connected with the upper end of the spring group, and a lower short shaft is connected with the lower end of the spring group. The flexible pipe is arranged outside the spring group. Upper short shaft sleeves and lower short shaft sleeves are respectively arranged on the upper short shaft and the lower short shaft. The upper short shaft is connected with a steering wheel, and the lower short shaft is connected with a steering device. The directional deformer is arranged on the short shaft sleeve of the upper short shaft, and a return positive guide rail of the directional deformer is in the shape of a horn to be clamped on the upper short shaft sleeve. A damping spring is arranged between the return positive guide rail and a seat frame. The safety steering shaft for an automobile steering wheel has the advantages that the safety steering shaft for an automobile steering wheel has reasonable structure, the safety steering shaft for an automobile steering wheel can protect the safety of a driver when an automobile collides.

Description

Vehicle steering safety steering shaft

The utility model relates to a kind of safety device of motor turning.

Present vehicle steering steering shaft links to each other with bearing circle by a straight tube, and when automobile bumped, because action of inertia, the bearing circle that makes the driver be easy to be connected on the steering shaft was wounded.Wounding in traffic accident like this is very common.

The purpose of this utility model provides a kind of vehicle steering safety steering shaft of protecting driver's safety when auto against.

The purpose of this utility model is achieved in that this steering shaft is by minor axis. short sleeve. and spring assembly. flexible pipe. directional deformation device etc. is formed, the spring assembly upper end connects goes up minor axis, the lower end is connected down on the minor axis, the spring assembly outside is a flexible pipe, on. on respectively having on the following minor axis. following short sleeve, last minor axis closure dish, following minor axis connects deflector, the directional deformation device is arranged on the short sleeve of last minor axis, the positive guide rail that returns of directional deformation device is horn-like, be stuck on the short sleeve, between the mounting of time positive guide rail and directional deformation device damping spring arranged.

Described flexible pipe upper end is connected on the short sleeve, and the lower end is connected down on the short sleeve.

The utility model advantage is rational in infrastructure, can protect driver's safety when auto against.

Below in conjunction with drawings and Examples the utility model is described.

Fig. 1 is the utility model constructional drawing.

Fig. 2 is that the A of Fig. 1 is to cutaway view.

(1) goes up minor axis among the figure. and (2) go up short sleeve. (3) directional deformation device. (4) spring assembly. (5) flexible pipe. (6) are minor axis down. and (7) are short sleeve down. and (8) return positive guide rail. (9) damping spring. (10) directional deformation device mounting.

When auto against; because action of inertia; minor axis (1) and upward short sleeve (2) landing forward from the exit skirt that returns positive guide rail (8) of directional deformation device (3) on the bonded assembly of spring assembly (4) upper end; bearing circle is rolled over downwards; it is the bump that is subjected to bearing circle that thereby actv. has been protected driver's health, by the damping spring (9) that goes back to (8) on the positive guide rail bearing circle is restored to the original state again afterwards.

When automobile normal running, directional deformation device (3) stop steering shaft with the direction of velocity reversal angle on deformation, increase steering shaft security and stability when non-collision.
