Abstract
Description
The present invention relates to a steering column for a vehicle.
In the case of a conventional steering column for a vehicle, an outer tube coupled with a tilting bracket and a mounting bracket due to its own weight or an external impact is rotated when the assembled or assembled product is completed, As shown in Fig.
As a result, there is a problem in that the product is deteriorated in performance due to an error in the product, and the assembled product is disassembled and reassembled to degrade the precision of the product.
It is an object of the present invention to provide a steering column for a vehicle which can prevent rotation of an outer tube even during assembling or transportation of components by improving the structure of the steering column, .
According to an aspect of the present invention, there is provided a steering column for a vehicle including a hollow inner tube surrounding a steering shaft, a slot formed in a direction of a steering axis at one end of the inner tube, A hollow outer tube including a pair of distance flanges extending in a direction perpendicular to the steering shaft from an outer circumferential surface so as to face each other at both sides of the slot, the telescopic hole being formed in the outer flange, A rotation preventing block disposed between the pair of distance flanges and restricting the rotation of the outer tube; a rotation preventing block coupled to the outside of the pair of distance flanges and having a tilt hole formed at a position corresponding to the telescope hole, A tilt bracket coupled to one side of the tilt bracket, An adjustment lever, and a fixing bolt penetrating through the telescope hole and the tilt hole and coupled with the adjustment lever.
The rotation preventing block may include a fastening portion to be fastened to the inner tube, and a body portion formed integrally with the fastening portion and disposed outside the inner tube to support the outer tube.
Wherein the fastening portion is formed by a plurality of spaced apart portions along a longitudinal direction of the body portion, a leg portion protruding from one surface of the body portion and having a width corresponding to the slot, and a fastening portion extending from the end portion of the leg portion, And an engaging portion which is engaged with the inner surface of the inner tube.
The inner tube may be formed with a fastening hole for fastening the fastening portion.
The body portion may have a width corresponding to a distance between the pair of distance flanges, and a slot may be formed on the inner side of the body portion to penetrate the body portion.
A support protrusion may be further formed on an upper surface of the body portion to support an elastic member restricting movement of the tilt bracket.
A cushioning member may be further provided around the leg portion.
According to another aspect of the present invention, there is provided a steering column for a vehicle including a hollow inner tube surrounding a steering shaft, a slot formed in a direction of a steering axis at one end of the inner tube, A pair of distance flanges extending in a direction perpendicular to the steering shaft from the outer circumferential surface so as to face each other, and a telescopic hole is formed in the outer circumferential surface of the outer tube; a fastening portion penetrating the slot to fasten the inner tube; A rotation preventing block disposed between the pair of distance flanges and supporting the outer tube to limit the rotation of the outer tube; a rotation prevention block coupled to the outside of the pair of distance flanges and corresponding to the telescope hole A tilt bracket formed with a tilt hole and coupled to the mounting bracket, And a fixing bolt penetrating through the telescope hole and the tilt hole and engaged with the adjustment lever, wherein the coupling portion is protruded from one surface of the body portion, A leg portion extending along the longitudinal direction and a retaining portion extending from the leg portion to the width direction side of the body portion, wherein the inner tube is formed with a guide rail in which the fastening portion is fastened through sliding.
According to another aspect of the present invention, there is provided a steering column for a vehicle including a hollow inner tube surrounding a steering shaft, a slot formed in a direction of a steering axis at one end of the inner tube to which the inner tube is inserted, A hollow outer tube including a pair of distance flanges extending in a direction perpendicular to the steering shaft from the outer circumferential surface so as to be opposed to each other at opposite sides thereof and having a telescope hole formed therethrough, a fastening portion passing through the slot and fastened to the inner tube, A rotation preventing block disposed between the pair of distance flanges and including a body portion for supporting the outer tube to limit the rotation of the outer tube; a rotation prevention block coupled to the outside of the pair of distance flanges and corresponding to the telescope hole A tilt bracket coupled to the mounting bracket, A control lever coupled to an outer surface of one side of the tilt bracket, and a fixing bolt penetrating the telescope hole and the tilt hole and coupled with the control lever, A plurality of spaced apart legs protruding outwardly from one surface of the body and an arch-shaped elastic support connecting the legs, wherein the inner tube is formed with a fastening hole for fastening the fastening portion.
According to the present invention, by providing the rotation preventing block which is disposed between the pair of distance flanges while being fixed to the inner tube and restricting the rotation of the outer tube, even when assembling or transferring the steering column, It is possible to prevent a component such as a tilted bracket from rotating due to its own weight or external impact.
In addition, since the components such as the outer tube and the tilt bracket coupled with the outer tube are prevented from rotating due to their own weight or an external impact, it is possible to prevent the components from being displaced from each other in the correct position, In addition, it is possible to prevent the process of disassembling and reassembling the already assembled products beforehand, thereby improving the production efficiency.
