Abstract

The present invention is to prevent the noise generated by the interaction between the yoke and the yoke plug by the impact of the steering wheel from the road surface to the yoke through the rack bar, to strengthen the elastic force provided to the rack bar in the yoke It makes the rack bar and pinion tighter and contributes to noise reduction due to retraction of the yoke.

Description

Noise Reduction Apparatus for Steering Gearbox

The present invention relates to a steering device of a vehicle, and more particularly, to a technique for reducing noise generated in a steering device by a load transmitted from a wheel through a rack bar of a steering device.

Referring to FIG. 1, the conventional steering apparatus allows the rack bar 500 to be compressed to the pinion 502 to secure a firm engagement state, thereby effectively transmitting the rotational motion of the pinion 502 to the linear motion of the rack bar 500. In order to be able to do so, a yoke 506 is provided to closely contact the rack bar 500 toward the pinion 502.

That is, the yoke plug 504 is fastened to the gearbox together with the press-elastic member 508 in the state where the yoke 506 is inserted into the gearbox to push the rack bar 500 toward the pinion 502. As a result, the yoke 506 is always in close contact with the rack bar 500 toward the pinion 502.

However, when the impact that the wheel receives from the road surface while driving the vehicle enters through the rack bar 500, the rack bar 500 applies the force toward the yoke 506 by the inclination angle of the portion engaged with the pinion 502. When the magnitude of this force increases, the yoke 506 strikes the yoke plug 504 to generate noise.

The present invention is to prevent the noise generated by the interaction between the yoke and the yoke plug by the impact of the steering wheel from the road surface to the yoke through the rack bar as described above, provided to the rack bar in the yoke The purpose of the present invention is to provide a noise reduction device for a steering gearbox which can strengthen the elastic force to strengthen the engagement state of the rack bar and pinion and contribute to noise reduction due to the retreat of the yoke.

The noise reduction device of the present invention the steering gear box to achieve the object as described above

A blocking member interposed between the yoke and the yoke plug to block direct contact between the yoke and the yoke plug;

A first elastic member installed between the blocking member and the yoke to apply an elastic force in a direction that is opened to each other;

And a second elastic member installed between the blocking member and the yoke plug to apply an elastic force in a gaping direction.

The blocking member is formed with a guide protrusion protruding toward the yoke, with a central portion facing the yoke;

The yoke is formed with a guide rib forming a guide groove for inserting the guide projection of the yoke toward the blocking member;

The first elastic member may have a structure consisting of a coil spring formed to surround the outside of the guide rib into which the guide protrusion is inserted.

The blocking member is provided with an elastic member insertion groove so that the second elastic member is inserted into the central portion facing the yoke plug;

The yoke plug is provided with an elastic member support groove so that the other side of the second elastic member is inserted corresponding to the elastic member insertion groove;

The second elastic member may have a structure consisting of a coil spring having both ends inserted into the elastic member insertion groove and the elastic member support groove.

The blocking member is preferably formed of a plastic material or urethane material.

The present invention is to prevent the noise generated by the interaction between the yoke and the yoke plug by the impact of the steering wheel from the road surface to the yoke through the rack bar, to strengthen the elastic force provided to the rack bar in the yoke It makes the rack bar and pinion tighter and contributes to noise reduction due to retraction of the yoke.

2, the embodiment of the present invention is interposed between the yoke (1) and the yoke plug (3) and the blocking member (5) for blocking direct contact between the yoke (1) and the yoke plug (3) and ; A first elastic member (7) installed between the blocking member (5) and the yoke (1) to apply an elastic force in a direction in which they intersect; It comprises a second elastic member (9) installed between the blocking member (5) and the yoke plug (3) to apply an elastic force in the direction of each other.

That is, by blocking the direct contact between the yoke 1 and the yoke plug 3 at the source, the noise generated while directly hitting the yoke plug 3 while the yoke 1 is retracted is not generated. Therefore, the blocking member 5 is formed of a plastic material or a urethane material, so that the noise is not generated or reduced even when colliding with the yoke 1 or the yoke plug 3, so that the shock can be absorbed. Do.

The blocking member 5 has a central portion facing the yoke 1 with a guide protrusion 11 protruding toward the yoke 1, and the yoke 1 faces the yoke 1 toward the blocking member 5. A guide rib 13 forming a guide groove 19 for inserting the guide protrusion 11 of 1) is formed, and the first elastic member 7 includes the guide rib in which the guide protrusion 11 is inserted. 13) is a structure consisting of a coil spring formed to surround the outside.

In addition, the blocking member 5 is provided with an elastic member insertion groove 15 so that the second elastic member 9 is inserted into the central portion facing the yoke plug 3, and the yoke plug 3 has the The elastic member support groove 17 is provided to correspond to the elastic member insertion groove 15 so that the other side of the second elastic member 9 is inserted, and the second elastic member 9 has the elastic member insertion groove ( 15) and a coil spring having both ends inserted into the elastic member support groove 17.

Accordingly, the blocking member 5 has a cross-sectional shape similar to that of a hat, wherein the second elastic member 9 is inserted into the hat and the first elastic member 7 is inserted into the hat. It is a structure that has become a form.

The noise reduction device of the steering gearbox configured as described above is usually used to push the yoke 1 with the elastic force provided by the first elastic member 7 and the second elastic member 9 to the rack bar 21. By ensuring the stably in close contact with the pinion 23, it is possible to ensure a smooth and stable movement of the rack bar 21 during the rotation of the pinion (23).

On the other hand, when the impact from the road surface input from the steering wheel reaches the yoke 1 by the rack bar 21, the elastic force provided by the first elastic member 7 and the second elastic member 9 Even when the yoke 1 is retracted primarily and the retracted while contracting both the first elastic member 7 and the second elastic member 9, the yoke 1 is the yoke plug 3 It is blocked by the blocking member 5 without being in direct contact with, so that the metallic contact noise that has conventionally been generated between the yoke 1 and the yoke plug 3 is not generated.

1 is a view showing the structure of a steering gearbox according to the prior art,

2 is a view for explaining the configuration of the noise reduction device of the steering gear box according to the present invention.
