Abstract
A suspension subframe of a vehicle according to an exemplary embodiment of the present invention includes a first section through which a load of a power train is input, and a second section through which a load of a suspension system is input from both sides thereof with the first section interposed therebetween. It comprises a main frame consisting of, characterized in that for forming the ribs of different arrangement shape on the first section and the second section of the main frame.
Description
An exemplary embodiment of the present invention relates to a suspension of a vehicle, and more particularly, to a subframe for a suspension of a vehicle to secure NVH performance and durability performance by loads input from a power train and a suspension system simultaneously. will be.
In general, the suspension of the vehicle is a device that connects the axle and the vehicle body to prevent the axle from being transmitted directly from the road surface while transmitting vibrations, shocks and external forces to the vehicle body to prevent damage to the vehicle body and cargo and improve ride comfort.
In particular, in the suspension mainly applied to small passenger vehicles, as shown in FIG. 1, the
In addition, an H-
Here, the
In this case, the
Meanwhile, in the related art, in order to reduce noise and vibration caused by a load input to a subframe through a suspension system such as a power train and a
However, in the related art, when a rigid stiffener is locally added to the load input unit or a dynamic damper is mounted, the weight of the vehicle is increased, the parts price is increased, and the fundamental stiffness / durability of the entire frame and the noise and vibration are fundamental. The situation is not solved.
Exemplary embodiments of the present invention have been created to improve the problems as described above, the suspension of the vehicle to ensure the NVH performance and durability performance by the load input from the powertrain and suspension system as a simple structure at the same time Provides a subframe for
To this end, a suspension subframe of a vehicle according to an exemplary embodiment of the present invention includes a first section into which a load of a power train is input, and a load of a suspension system from both sides thereof with the first section interposed therebetween. It includes a main frame consisting of two sections, characterized in that to form a rib of different arrangement shape on the first section and the second section of the main frame.
In the subframe for suspension of the vehicle, the main frame may form a first rib having an orthogonal shape with respect to the front-rear direction on the first section.
In the subframe for suspension of the vehicle, the main frame may form a second radial rib on the front and rear directions on the second section.
According to the subframe for suspension of the vehicle according to the exemplary embodiment of the present invention as described above, the noise and vibration caused by the load input in different directions with respect to the first and second sections of the main frame are different from each other By reducing through the ribs, the NVH performance can be secured, the rigidity and durability of the main frame can be ensured, and the weight can be reduced.
These drawings are for the purpose of describing an exemplary embodiment of the present invention, and therefore the technical idea of the present invention should not be construed as being limited to the accompanying drawings.

In addition, on the second section S2, NVH performance with respect to a load input from the suspension system in the front-rear, left-right direction (vertical and horizontal directions) can be ensured, and the front-rear left-right direction is centered to satisfy the durability performance of the
Accordingly, the
In the present embodiment, as shown in FIG. 4B, the noise and vibration caused by the load of the suspension system input to the second section S2 in the front, rear, left, and right directions (arrow directions in the drawing) are applied to the
That is, in the present exemplary embodiment, the
As a result, in the present embodiment, consumer dissatisfaction with vibration and noise can be solved, thereby increasing customer satisfaction with the vehicle.
Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. Naturally, it belongs to the scope of the invention.
