Suspension system for vehicle

Abstract

A suspension system for a vehicle is disclosed and may include a knuckle configured of rotatably supporting a wheel, and a lower control arm mounted along a vehicle's width direction and connecting the knuckle and a vehicle body, wherein the lower control arm may include a wheel-side end portion connected to a lower portion of the knuckle through a lower external joint, a vehicle body-side front end portion connected to the vehicle body through a front lower inner joint, and a vehicle body-side rear end portion connected to the vehicle body through a rear lower inner joint, wherein one of thevehicle body-side front and rear end portions is connected to a portion of the vehicle body through a compliance control arm.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0161198 filed on December 13, 2018, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a suspension system for a vehicle. Background technique [0004] A vehicle is generally provided with a suspension system between a drive shaft and a vehicle body as a device configured to improve riding comfort and / or driving stability by reducing shock or vibration transmitted from a road surface while the vehicle is running. [0005] This suspension system serves several functions of the vehicle. The suspension system provides ride comfort by cutting off irregular impact inputs transmitted from the road to the body. The suspension system also provides driving convenience by properly controlling the rocking motion of the vehicle body caused by the driver's driving input or ...

Problems solved by technology

[0008] Although such multi-link suspensions actually achieve performance improvements over conventional suspensions, multi-link suspensions also have limitations in optimally controlling wheel alignment

Multi-link suspensions also exhibit the disadvantages of increased production costs due to increased number of parts and poor space efficiency because multiple links can be included in a limited space

However, double wishbone or MacPherson strut suspensions may exhibit the disadvantages of difficult traction control and lateral stiffness when lateral forces and / or braking forces are applied

[0010] In the case of suspensions with A-arms (which have a single knuckle-side connection point and two body-side connection points), although traction characteristics can be achieved when lateral forces and / or braking forces are applied, But lateral stiffness may be worse
