Description

A wheel carrier for a vechicle

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wheel carrier for a vehicle, and more particularly, to a wheel carrier for a vehicle which has enhanced strength of an assist arm fastening portion to improve durability and moldability.

2. Description of the Related Art [0002] Generally, a suspension of a vehicle connects an axle and a vehicle body, thereby preventing a vibration or an impact from a road surface from being directly transmitted to a vehicle body during traveling.

These suspension devices are classified into a single-axle suspension system and an independent suspension system depending on the type of axle, and an independent suspension system is generally used for a passenger car that emphasizes ride comfort and maneuverability.

The configuration of the independent suspension device is shown in Korean Laid-Open Publication No. 10-2015-0066110.

The wheel is mounted on a carrier, which is connected to the cross member through an upper arm, a lower arm, and an assist arm, and is connected to a side member (not shown) below the vehicle body through a trailing arm.

The trailing arm is connected to the front of the carrier to support the forward and backward movement of the carrier, and the front end is formed with a bush made of an elastic body to absorb a part of the inner and outer behavior. The upper arm, the lower arm, And a vertical movement of the carrier is supported by a spring and a shock absorber.

The upper arm, the lower arm, and the assist arm connect the cross member disposed in the vehicle width direction to the carrier, and the lower arm is equipped with a spring and a shock absorber.

A carrier wheel and a braking device are mounted, and the wheel is configured to be rotatably mounted in connection with an axle fitted into the carrier.

In the case of the carrier shown in the prior art, there has been a point that there is a problem in durability because it is difficult to secure large rigidity by providing the assist arm fastening portion in a cantilever type.

Also, there is a problem in setting the parting line and the moldability in the mold when the cantilever type is applied, and a method of improving the productivity is needed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wheel carrier for a vehicle which can improve rigidity and formability.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, An extension rib extending from the hub bearing fastening part to one side and having a predetermined thickness; And an assist arm fastening portion provided on the extension rib and spaced apart from each other.

The assisting arm fastening portion extends downward from a lower surface of the extended rib, and is provided in a plurality of spaced apart spaces.

Wherein the assist arm fastening portion comprises: The first assist arm fastening portion includes a first flange portion and a first through hole formed in the first flange portion. The first assist arm fastening portion includes a first assist arm fastening portion and a second assist arm fastening portion spaced apart from the first assist arm fastening portion. The arm fastening portion includes a second flange portion and a second through hole formed in the second flange portion, wherein the first through hole and the second through hole are arranged on the same axial line.

And a trailing arm fastening part disposed on one side of the rib and extending upward, wherein the rib is provided to connect between the trailing arm fastening part and the assist arm fastening part.

And the extension rib is formed so that its thickness decreases from the hub bearing coupling portion toward the assist arm coupling portion.

And the extension rib is formed with a recess for strengthening the strength.

A lower arm coupling portion provided below the hub bearing coupling portion and a lower coupling portion provided between the lower arm coupling portion and the assist arm coupling portion, wherein a lower surface of the lower coupling portion and a lower surface of the extended rib are the same And is arranged on a plane.

According to the present invention, the assisting arm fastening portion can be applied as a pair of fork type, and a greater rigidity can be ensured as compared with the prior art of the cantilever type.

The strength of the assisting arm can be improved because the assisting arm fastening portion is connected to the lower connecting portion connected at the extension rib and the lower arm fastening portion extending from the hub bearing fastening portion.

In addition, since the trailing arm fastening portion and the assist arm fastening portion are connected to each other by the extending ribs without directly connecting thereto, the moldability can be increased while reducing the influence of each other.
