Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll suppressing means of a motor vehicle, and includes a subframe 30 having an engine 10 and a transmission 20 installed at a center of a U-shape and rotatable on both sides of the subframe 30, respectively. In the roll suppression means of a vehicle provided with a lower arm provided and a roll suppression means fixed to the lower arm to reduce the inclination of the vehicle body, the roll suppression means has a torsion bar (100) shape and one side of the subframe (30). It is fitted to the other side of the lower arm 200, which is coupled to the bush and fixed to the left and right members 31 and 32 constituting the subframe 30, so that the roll suppression means is left to right of the subframe. The design freedom can be improved by not crossing the right or left to right side.

Description

Roll Inhibitors of Vehicles

The present invention relates to a roll inhibiting means of a vehicle, which is designed to greatly improve the design freedom.

In general, the suspension of the vehicle is connected to the axle and the body so that the vibration or shock received from the road surface is not directly transmitted to the body while driving, thereby preventing damage to the body and cargo and improving ride comfort. And a chassis spring for mitigating, a shock absorber for controlling the free vibration of the chassis spring to improve ride comfort, and a roll suppressing means for preventing rolling of the vehicle.

In this case, the roll suppression means does not work when both ends are mounted on the left and right lower suspension arms and the left and right wheels move up and down at the same time, but the springs are twisted when the left and right wheels move up and down relatively. Resilience plays a role in reducing the tilt of the car body.

Figure 1 schematically shows a state in which the roll suppression means according to the prior art is installed, the subframe 30, the engine 10 and the transmission 20 is installed in the center of the K-shaped, and this subframe The lower arm 40 is rotatably provided at both sides of the 30, and both ends are attached to the lower arm 40, and roll suppression means (stabilizer bar) 50 is provided to reduce the inclination of the vehicle body.

That is, when the left and right wheels at the both ends of the roll-suppressing means 50 simultaneously move up and down at the same time, the torsional force does not work, but when they move up and down relative to each other, the torsional force is distorted. Let's go.

However, since the roll suppression means 50 is coupled across the subframe 30 because it is coupled to the lower arm 40 on the left and right, there is a drawback that the design freedom is lowered.

Accordingly, the present invention has been made to solve the above-described drawbacks, the roll suppression means is fixed to one side is fitted to the other side of the lower arm bush-coupled to the subframe and not to rotate to the left and right members constituting the subframe It is an object of the present invention to provide a roll suppressing means for a vehicle which can improve the design freedom since the roll suppressing means does not cross the left to right side or the right to left side of the subframe.

The present invention for achieving the above object is a subframe in which an engine and a transmission are installed in the center, a lower arm rotatably provided at both sides of the subframe, and a tilt of the vehicle body fixed to the lower arm. It is provided with a roll suppression means for reducing the roll suppression means is a torsion bar shape, one side is fixed to the other side of the lower arm bush-coupled to the subframe and fixed so as not to rotate to the left and right members constituting the subframe It is structured.

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

2 is a schematic diagram illustrating a state in which a roll suppressing means of a vehicle according to the present invention is installed, and FIG. 3 is a side view in G direction of FIG. 2, with the same reference numerals being attached to the same parts as in FIG. Is omitted.

As shown in FIG. 2, the present invention is a subframe 30 in which an engine 10 and a transmission 20 are installed at a center of a U-shape and rotatably installed at both sides of the subframe 30. In the roll suppression means of a vehicle provided with a lower arm and a roll suppression means fixed to the lower arm to reduce the inclination of the vehicle body, the roll suppression means has a torsion bar (100) shape and one side of the roll restraint means is formed on the subframe (30). It is fixed to the other side of the bushing lower arm 200 and fixed to the left and right members 31 and 32 constituting the subframe 30.

Herein, the roll suppression means 100 includes a cylindrical portion 110 fixed to the lower arm 200, a quadrilateral cross section 120 fixed to the bolt 300 to the subframe 30, and the four edges. It is a structure having a towing hook 130 extending forward from the surface portion 120.

In addition, as shown in FIGS. 4 to 6, the subframe 30 in which the roll suppression means 100 is installed, the roll suppression means 100 may be installed in the lower plate 33 constituting the subframe 30. The bent portions 33a, 33b, and 33c are formed to be formed so that the nut 400 is welded to the lower plate 33 to fasten the bolt 300.

Next, the operation and effects according to the configuration of the present invention will be described.

To use the T-shaped cross member to secure the collision stability, remove the stabilizer bar, the roll suppression means that hinders design freedom in applying the K-shaped subframe, and use the torsion bar 100 as the roll suppression means. This can suppress the design freedom is improved.

In addition, bending portions 33a, 33b, 33c are formed on the lower plate 33 of the subframe 30 so that the roll suppression means 100 can be easily installed. The bar 100 is distributed to the rear or lower arm 200 of the subframe 30.

On the other hand, the towing hook 130 is formed at the end of the torsion bar (roll suppression means; 100) to facilitate the operation according to the traction.

As described above, according to the roll suppressing means according to the present invention, there is no effect that the state does not cross from the left to the right or the right to the left of the subframe, thereby improving the design freedom.

In addition, the bent portion is formed in the lower plate of the subframe to increase the rigidity has the effect that the load is distributed to the rear or lower arm of the subframe through the torsion bar even during a collision.

Although one specific embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various changes and modifications may be made by those skilled in the art based on the technical idea of the present invention.
