Description

Technical Field

[0001] This utility model relates to an automotive component, and more specifically, to an automotive front control arm assembly. Background Technology

[0002] The control arm is a crucial safety component in a car's suspension. It connects the steering knuckle, subframe, and controls the suspension's positioning parameters and load transmission during movement, requiring high rigidity and strength. Currently, in most vehicle front suspension systems, the front control arm is connected to the frame and wheels using a three-end connection: one end connects to the steering knuckle, and the other end connects to the subframe. The stabilizer bar is an auxiliary elastic element in the suspension, preventing excessive lateral roll during cornering, thus preventing vehicle rollover and improving ride comfort. The stabilizer bar is typically fixed to the control arm via a connecting bracket, which itself needs to be separately fixed to the control arm. Therefore, if the connecting bracket deforms or loosens, it can cause problems with the stabilizer bar connection, affecting vehicle safety performance.

[0003] Existing front control arms are typically mounted on the front subframe using mounting brackets, usually secured through two mounting points. This results in insufficient dynamic stiffness, poor strength, and low durability. For example, patent CN201914037U discloses a front control arm assembly for automobiles. This structure includes an arc-shaped front control arm body, with a steering knuckle ball joint connection at one end and a rear bushing assembly at the other. A front bushing assembly is located in the middle of the front control arm body, connecting it to the vehicle frame via the front and rear bushing assemblies. The front control arm body also features an integral support for connecting the stabilizer bar ball joint. While this front control arm body is connected to the subframe through two mounting points, it still suffers from insufficient dynamic stiffness, poor strength, and low durability.
