Problems solved by technology
[0008] The lower swing arm 10 in the above configuration has the first bush mounting portion 11 integrally welded to the end of the first arm 14 and the second bush mounting portion 12 integrally welded to the end of the second arm 15; Manufacturing is difficult and slow due to the soldering process of these parts
In addition, these welded parts can develop defects during manufacturing and crack during use, resulting in reduced durability
[0009] In addition, since the additional parts 11 and 14 are attached by welding, the total weight of the lower arm 10 increases

Embodiment Construction
[0040] Such as image 3 and Figure 4 As shown, the lower swing arm 100 for a vehicle suspension system according to an exemplary embodiment of the present invention has: a first bush installation part 110 and a second bush installation part 120, which are respectively located at the front side and the rear side; An arm 101 extending from the first bush mounting portion 110 to a ball joint mounting portion 130 ; and a second arm 106 extending integrally from the first arm 101 and connected to the second bush mounting portion 120 .
[0041] In this embodiment, the first arm 101 and the second arm 106 are integrally formed by forming separate steel plates. In this case, the end portion of the first arm 101 connected to the first bush mounting portion 110 is formed with a pair of ring members 102 and 103, such as Figure 5 and Figure 6 In part (a) shown.
[0042] A pair of ring members 102 and 103 are formed to be spaced apart from each other in the axial direction, and cont...

The present invention relates to a lower arm for vehicle suspension system comprising a first bush mounting part and a second bush mounting part mounted to a front member mounting assembly of a vehicle chassis to be spaced apart therebetween at front and rear, a first arm having one end part connected to the first bush mounting part and the other end part extruding laterally from the vehicle chassis to be connected to a ball joint mounting part to support a wheel mounting assembly, and a second arm having one end part extending integrally from the first arm and the other end part connected to the second bush mounting part, wherein the first arm is formed by forming a metal plate, the one end part of the first arm connected to the first bush mounting part has a pair of ring members which are formed by forming the metal plate to be parallel therebetween in an axial direction and to contact and support through their inner round surfaces an outer round surface of the first bush mounting part. Therefore, welding parts are removed in the manufacturing process so that easy manufacturing, high strength and weight reduction compared to the conventional art can be accomplished.
Description
technical field [0001] The present invention relates to a lower swing arm for a vehicle suspension system, and more particularly to a lower swing arm for a vehicle suspension system which can be easily manufactured by eliminating welding parts in the manufacturing process and which can achieve The purpose of increasing strength and reducing weight. Background technique [0002] There are many types of vehicle suspension systems, including Macpherson, Wishbone, trailing link, multi-link, and others. [0003] Among these vehicle suspension systems, a McPherson type vehicle suspension system is generally used as the front wheel suspension system of the vehicle, the front wheel suspension system includes: a wheel mounting assembly, which is attached to a tire; a knuckle arm, which supports the wheel mounting assembly; A lower arm that rotatably supports a knuckle arm; a shock absorber that reduces vibration transmitted to the knuckle arm; and the like. [0004] Examples of the...
