Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to a control arm with an installation included angle. Background Art

[0002] In the prior art, the control arm is an important component in the vehicle suspension system, mainly responsible for connecting the vehicle body and the wheels, helping the wheels to maintain stability when moving up and down, ensuring the proper angle of the wheels, and maintaining the relative position of the wheels. The main function of the control arm is to withstand lateral forces and braking forces during steering when the vehicle is running, stabilize the chassis structure and the vehicle position, reduce the sway during driving, and improve the stability of the vehicle. However, in the existing control arm structure, for example, the patent with the application number CN201821964985.X discloses an adjustment arm assembly for adjusting the angle of vehicle wheels. The ball head assembly is arranged in the same plane as the mounting ring through the U-shaped arm body. The ball head assembly is connected to the swing bearing of the wheel hub through a self-locking nut, and the mounting ring is connected to the vehicle suspension through a rubber sleeve. An included angle of 90 degrees is formed between the plane where the U-shaped arm body is located and the axis of the swing bearing. When the vehicle body rises relative to the wheels, it will cause one side of the mounting ring corresponding to the U-shaped arm body to be lifted, making the included angle between the plane where the U-shaped arm body is located and the axis of the swing bearing greater than 90 degrees. Such a state will not only affect the transmission of force during vehicle operation, but more seriously, it will cause the ball head assembly on the control arm to break, greatly reducing the service life of the ball head assembly.
