The present invention relates to a stabilizer bar structure of a vehicle, and more particularly, to a stabilizer bar structure of a vehicle in which the length change in the vehicle width direction is freed.

In general, the suspension system of the vehicle has a structure that connects the axle and the body so that vibrations or shocks received from the road surface are not directly transmitted to the body while driving, thereby preventing damage to the body and cargo and improving ride comfort. The apparatus generally includes a chassis spring for mitigating an impact received from a road surface, a shock absorber for controlling the free vibration of the chassis spring to improve ride quality, and a stabilizer bar for preventing rolling of the vehicle.

Here, the chassis spring is installed between the vehicle body and the wheel to have a function to absorb the shock and vibration of the wheel transmitted from the road surface while driving so as not to be transmitted to the vehicle body, metal springs, rubber springs and air springs of various types Etc. are used.

In addition, the shock absorber is a device for absorbing the natural vibration generated by the impact of the spring during the driving of the vehicle to quickly attenuate the vibration to improve the riding comfort, and converts the upper and lower kinetic energy into thermal energy. Although there are solid friction type and hydraulic type according to the method, hydraulic type is generally used in many cases. In addition, there are single acting type which exerts attenuation force at the time of stretching and double acting type which exerts attenuation force at both stretching and compression.

On the other hand, the stabilizer bar is mounted at both ends of the left and right lower suspension arms and does not work when the left and right wheels move up and down at the same time, but when the left and right wheels move up and down with each other, the spring restoring force is generated. This will reduce the inclination of the car body.

However, the conventional stabilizer bar has a problem in that it cannot be shared between models having a shape of one continuous beam, requiring similar stiffness and having different distances between wheels.

Accordingly, the present invention is to solve the above-described problems, the center portion is separated, so that the separated portion is possible to move relative to the vehicle width direction to provide a stabilizer bar structure of the vehicle is free to change the length thereof There is a purpose.

As a technical configuration for achieving the above object, the present invention, in the stabilizer bar structure of the vehicle which is formed long in the vehicle width direction so as to connect the left and right lower suspension arms to form a suspension device, to transmit the torsion, one side lower And a first stabilizer bar connected to the suspension arm, a second stabilizer bar connected to the other lower suspension arm, and a connecting portion connecting the first and second stabilizer bars to move relative to the vehicle width direction. By providing a riser bar structure.

In addition, in the stabilizer bar structure of the vehicle according to the present invention, the first and second stabilizers, the slider formed at the end facing each other, and so as to protrude outward more than the outer peripheral surface of the first and second stabilizers A protrusion formed in the slider, the connecting portion comprising: a main body accommodated to slide the slider in the vehicle width direction; guide grooves formed in the main body to receive the protrusion in a vehicle width direction; and both ends of the main body; It may have a stopper protruding to surround the first and second stabilizers in. In this case, the slider is formed to form a '+' shape protruding in all directions, the main body is preferably formed with a guide groove in all directions to accommodate the projection.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The suspension of a vehicle connecting the axle and the vehicle body is the same as a conventional structure, and the present invention has a structure in which the stabilizer bars constituting the suspension are separated from each other in the center and mounted on the lower suspension arms of the left and right, respectively.

More specifically, the stabilizer bar of the present invention is separated from each other and the first stabilizer bar having one end connected to each other by the connecting portion 30 at the center of the vehicle and the other end mounted on the lower suspension arms of the left and right, respectively ( 10) and the second stabilizer bar 20.

The first and second stabilizer bars 10 and 20 have sliders 12 and 22 at ends that face each other, and the sliders 12 and 22 have first and second stabilizer bars 10. ) 20 may be integrally formed or separately configured and fixed.                     

The sliders 12 and 22 have protrusions 13 and 23 protruding outward from the outer circumferential surfaces of the stabilizer bars 10 and 20, and the protrusions 13 and 23 have stabilizer bars 10. At least two or more are formed along the circumferential direction of the (20). In the present invention, it is shown that the protrusions 13 and 23 of the sliders 12 and 22 are each provided with four protrusions 13 and 23 arranged so as to have a substantially '+' shape.

The connecting portion 30 includes a main body 32 in which the sliders 12 and 22 of the first and second stabilizer bars 10 and 20 are slidably moved in the vehicle width direction, and the main body 32 of the main body 32. Both ends have stoppers 34 that are bent to surround the outer circumferential surfaces of the first and second stabilizer bars 10 and 20.

At this time, the inside of the main body 32 has a guide groove 32a having the same shape as the outer shape of the sliders 12 and 22, so that the first and second stabilizer bars 10 and 20 have a slider ( 12) and rotation by the guide groove 32a is prevented.

In addition, the main body 32 of the connecting portion 30 is preferably a structure in which the central portion is separated from each other and coupled by the bolt 36.
