BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rear suspension of an automotive internal link type, and in the past, when an integral link type rear suspension unit is made of aluminum, There is a problem that the unit price is increased.
Accordingly, the present invention is an automotive rear-wheel suspension system of an automotive rear-wheel suspension system, which includes an upper control arm 100, a track rod 200 and an integral link 300, And a lower control arm 600 connecting the subframe 400 of the vehicle with the wheel carrier 500 and formed of a steel material.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automotive internal link type rear wheel suspension apparatus, and more particularly, to an automotive internal link type rear wheel suspension apparatus, The lower control arm is formed by a steel material having a strong rigidity, and the lower control arm is formed by a lower control arm sub body and a lower control arm main body, respectively. The lower control arm sub body and the lower control arm main body are welded to form a lower control arm To an automotive integrated link type rear suspension device capable of reducing the production cost of components of a vehicle and improving the design satisfaction of a vehicle.
In general, an integral link type, which is one type of rear suspension suspension of a vehicle, is composed of a total of four connecting members for controlling the operation of the suspension.
The lower control arm of the integral-link type rear suspension unit is a member responsible for a large part of the external force applied to the wheel, so that a high strength rigidity is required.
In addition, the lower control arm is connected to various parts around it at the same time, so its shape is complicated and it is mainly produced by casting method.
However, when the lower control arm is made of cast iron like the other parts, it is made of aluminum because it is not suitable for the suspension because it is heavy.
However, such an automotive internal link type rear suspension apparatus has the following problems.
That is, when an integral link type rear suspension unit is manufactured from aluminum, there is a problem in that the cost of the vehicle is increased due to a large amount of material cost due to the characteristics of aluminum material having a higher price than cast iron.
In addition, when an integral link type rear suspension unit is made of an aluminum material, the volume of the rear suspension unit is increased, thereby lowering the design freedom of the vehicle.
Accordingly, an object of the present invention is to provide a rear suspension suspension for an automotive internal link, which is one of the rear suspension devices of an automobile, and which is capable of reducing the parts production cost of the vehicle and improving the design satisfaction of the vehicle, The lower control arm is formed of a lower control arm sub body and the lower control arm main body are formed respectively, and the lower control arm sub body and the lower control arm main body are respectively welded to the lower control arm A problem arises in that the cost of a vehicle increases due to the material cost of the aluminum material having a higher unit price than that of cast iron when an integral link type rear suspension unit is made of an aluminum material and an aluminum- When the suspension device is manufactured, the volume becomes large, The present invention provides an automotive integrated link type rear suspension device configured to effectively solve the problem of reduced design freedom of the vehicle.
The present invention relates to a rear suspension suspension of an automotive internal link type, which is one of the rear suspension systems of an automobile. The rear suspension suspension system comprises an upper control arm, a track rod and an integral link, And a lower control arm connected to the wheel carrier and formed of a steel material.
The lower control arm is formed as a lower control arm sub body and the lower control arm main body, respectively. The lower control arm sub body and the lower control arm main body, which are respectively formed, are welded to form a lower control arm. The control arm is formed of a steel material. The lower control arm constituting the integral-link type rear suspension unit is formed of a steel material having a stiffness higher than that of aluminum. By reducing the volume of the lower control arm, It is possible to achieve the object of the present invention.
The lower control arm of the present invention is formed of a steel material having a stiffness higher than that of aluminum. The lower control arm is formed of a lower control arm sub body and a lower control arm main body, The lower control arm is formed by welding the lower control arm main body to reduce the parts production cost of the vehicle.
Especially, since the lower control arm is formed by the cast iron having higher rigidity than aluminum, it is possible to reduce the size of the lower control arm, thereby improving the design satisfaction of the vehicle.

The present invention relates to an automotive rear-wheel suspension system of an automotive rear-wheel suspension system, which comprises an upper control arm (100), a track rod (200) and an internal link (300) And a
The
Particularly, the
The present invention relates to an automotive internal link type rear wheel suspension.
That is, together with the
In addition, by forming the
That is, since the lower control arm having a complicated structure can not be manufactured by the steel press method, which is a general steel manufacturing method, the lower control arm is divided into the lower control arm sub body and the lower control arm main body.
Especially, cast iron, which is a steel material, has a larger specific gravity than aluminum. Therefore, in order to maintain the same rigidity, the steel material may be smaller than the aluminum material, thereby reducing the space occupied by the lower control arm. It will be.
100: Upper control arm 200: Track load
300: Integral Link 400: Subframe
500: Wheel carrier 600: Lower control arm
