Description

[Technical field]

[0001] The utility model relates to the technical field of control arms, in particular to a front suspension upper control arm assembly. [Background technology]

[0002] The automobile suspension control arm, also known as the front suspension upper control arm assembly, is the guiding and force transmission element of the automobile suspension system, which transmits the force and torque acting on the wheel to the body. The existing control arms are as follows:

[0003] For example, patent announcement number CN203543560U discloses a suspension control arm assembly and a vehicle suspension system and automobile including the same. The suspension control arm assembly includes a control arm body and a ball pin connector, and the control arm body and the ball pin connector are connected by rivets. The ball pin connector of the utility model is connected to the control arm body by rivets, which has a simple process, reliable connection, and easy quality inspection, thus being more economical. In addition, the spatial arrangement of multiple rivets is regular, the force transmission is reliable, vibration resistance, and impact resistance are achieved, thus being safer and more reliable.

[0004] Although the suspension control arm assembly can have the effects of vibration resistance and impact resistance by changing the connection method between the ball pin connector and the control arm body, the vehicle will pass through some uneven roads during driving. When the vehicle is driving faster, the vehicle will pass through uneven roads, which will generate vibration force, and the vibration force will be transmitted to the control arm body. Since the control arm body is an integrated design, when the vibration source is transmitted to the control arm body, it will be subjected to hard vibration (as the name implies, the two ends of the control arm body are connected to the vehicle, which is the vibration source transmission source, and will be squeezed and vibrated by the vehicle and the bottom surface when vibrating). Once the control arm body is affected by hard vibration for a long time, if the strength of the control arm assembly is not high, it will easily cause it to bend or deform and be damaged, which will easily affect the safety of vehicle driving.
