Description

Fixing ASS'Y of steering column for car}

The present invention relates to a fixing structure of a steering column for a vehicle, and more particularly, it is characterized in that the lower end of the steering column is fixed to the vehicle body, but the vibration of the vehicle body is not transmitted to the handle while having a bearing force.

In general, the automotive steering column 1 has been improved to absorb shock while supporting the steering shaft therein, and the conventional structure for fixing the lower end to the vehicle body is as shown in FIG.

That is, the mounting member 2 is provided, but after the center of the flat plate is raised, a hole 2a is formed in the center, and the hole 2a is welded while the lower end of the steering column 1 is fitted.

The mounting member 2 is fixed to the vehicle body toward the engine room while being welded to the lower end of the steering column 1.

However, the conventional steering column fixing structure has the advantage of being firmly fixed, but since there is no structure that can block the vibration transmitted from the frame of the vehicle, both vibration and shock are transmitted to the steering wheel to obtain steering stability. There are no drawbacks.

Therefore, the present invention has been made in view of the conventional problems as described above to solve the problem, the main purpose of the invention is to fix the lower end of the steering column, to be fixed while blocking the vibration transmitted from the vehicle frame. On the other hand it is to be able to assemble using grooves and projections without a separate welding operation.

Characteristic means for this is a steering column welded to the stopper member to have a protruding wing on both sides of the lower outer peripheral surface, a plate portion for attaching to the vehicle body, a coupling portion raised in a cylindrical shape toward the steering shaft from the center of the plate portion, Mounting member having a through hole so that the protruding wing of the stopper member can be fitted in the center of the coupling portion, and the inner diameter portion to be inserted into the coupling portion of the mounting member, the inner diameter portion can be fitted to the steering column in the center, the inner diameter portion is interrupted It consists of a cushioning member consisting of an engaging groove formed in a wider width in a narrow width, and a guide groove formed on both sides so that the projecting wing can be fitted into the engaging groove.

Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a cross-sectional view showing a combined state of the present invention, Figure 2 is a cross-sectional view showing an exploded state of the present invention, as shown in the present invention is a steering column (1), the mounting member (2), a new cushion It is made of a member (3).

The steering column 1 is formed by welding the stopper member 11 so as to have the protruding vanes 12 on both sides of the lower outer circumferential surface, and the mounting member 2 includes a flat plate 21 for attaching to the vehicle body and the flat plate. It is formed of a coupling portion 22 is raised in a cylindrical shape toward the steering axis from the center of the portion, the through-hole 23 so that the projection wing 12 of the column and the stopper member 11 can be fitted in the center of the coupling portion 22 ), The buffer member 3 is formed in a disk-shaped rubber and embedded in the engaging portion 22 of the mounting member 2, and the inner diameter portion 31 through which the steering column can penetrate the center; In addition, the engaging groove 32 is formed in a wide width in a narrow width at the interruption of the inner diameter portion and consists of a guide groove 33 formed on both sides so that the protruding wing can be fitted into the engaging groove.

In this case, the shock absorbing member 3 integrally forms one or more protrusions 34 on the upper surface, and one or more small holes 24 corresponding to the upper surface of the engaging portion 22 of the mounting member 2. After that, when the protrusion 34 is pressed into the small hole 24, the shock absorbing member does not easily come out of the mounting member 2.

In the figure, reference numeral 25 denotes a buffer pad.

When assembling the present invention configured as described above, the cushioning member 3 is fitted to the coupling part 22 under the mounting member 2, and the respective guide grooves 33 and the through holes 23 are coincident with each other. By fitting the protruding wing 12 of the stopper member 11, and inserting the protruding wing 12 into the through hole 23 and the guide groove 33 matched in this way, when rotated 90 °, the protruding wing 12 is located in the engaging groove 32, so that it does not fall in the longitudinal direction of the steering column will have a bearing force.

The present invention as described in detail above, using the mounting member (2) to fasten the lower end of the steering column (1) to the vehicle body, instead of welding as in the prior art to form a thin protruding wing (12) on the steering column, mounting Since the engaging portion 22 of the member 2 has a built-in shock absorbing member 3 having an engaging groove 32 which can be caught when the protrusion blade 12 is inserted and rotated, vibration of the vehicle body is caused by steering. It is not delivered through columns and shafts, so it can have stability in operation and simplify assembly work.
