control arm

A control arm connects the wheel hub and steering knuckle to the frame of the vehicle. They are typically equipped with bushings on the frame side of the vehicle and a ball joint on the wheel side of the vehicle that allow flex and controlled movement according to road conditions and steering input from the driver.

The Control arm, as the guiding and force transmitting element of the automobile suspension system, transmits various forces acting on the wheel to the body, while ensuring that the wheel moves according to a certain trajectory. The Control arm connects the wheel to the body flexibly by means of ball hinges or bushings. The Control arm should have sufficient stiffness, strength and service life。

1, the control arm and the control arm bushing as the guidance and force transmission components of the automobile suspension system, the various forces acting on the wheel to the body, while ensuring that the wheel according to a certain trajectory. The control arms connect the wheels to the body flexibly through ball hinges or bushings respectively. The control arm (including the bushing and ball head connected with it) should have sufficient stiffness, strength and service life; 2, suspension system including worn control arm bushing refers to the body and tire between the spring and shock absorber composed of the entire support system. The function of the suspension system is to support the body and improve the feeling of riding. Different suspension Settings will make the driver have different driving feelings; 3, the seemingly simple suspension system integrates a variety of forces, determines the stability, comfort and safety of the car, and is one of the key components of modern cars.

1.The purpose of the automobile control arm can play a great role in the automobile. The control arm, as the guidance and force transmission component of the automobile suspension system, transmits various forces acting on the wheel to the body, and ensures that the wheel moves according to a certain track. 2.The control arm should have sufficient stiffness, strength and service life. The suspension system refers to the spring between the body and the tire and the shock absorber composed of the entire support system. The function of the suspension system is to support the body and improve the feeling of riding.

1. Functional characteristics of multi-link independent suspension: multi-link suspension can not only ensure a certain degree of comfort, but also make the wheel and the ground as vertical as possible and reduce the tilt of the body as much as possible due to the large number of connecting rods. It is possible to maintain the ground adhesion of the tire. Its handling performance and double fork arm suspension are closely matched. Because of ample space, and pay attention to comfortable performance and control stability, most high-gear cars use multi-link suspension. It can be said that multi-link suspension is the best gear for high-gear cars. 2. The material characteristics of multi-link independent suspension, multi-link suspension structure is relatively complex, the material cost, research and development experiment cost and manufacturing cost are much higher than other types of suspension, and its space is large, small and medium cars for cost and space considerations rarely use this suspension; 3. the role of multi-link independent suspension: as the name suggests, multi-link suspension is composed of three or more connecting rod, and can provide multiple directions of control, so that the tire has a more reliable driving track of the suspension structure. However, nowadays, because the three-link structure can no longer meet people's higher pursuit of chassis control performance, only the more accurate structure, more accurate positioning of the four-link and five-link suspension can be called the real multi-link type, the two suspension structures are usually applied to the front wheel and the rear wheel respectively. Take the five-link suspension commonly used in the rear wheel as an example. The five connecting rods refer to the main control arm, the front positioning arm, the rear positioning arm, the upper arm and the lower arm respectively. Among them, the main control arm can play the role of adjusting the front bundle of the rear wheel, so as to improve the stability of the vehicle and effectively reduce the friction of the tire.

1. Materials. The control arm ball head is made of all aluminum, and the front ball head is made of carbon steel. 2.In terms of usefulness. The control arm ball head is used for wheel steering motion, while the front ball head is used to make the car suspension and balance rod force transfer.

1. It can comprehensively improve the smoothness of the car ride, thus enhancing the driver's sense of smoothness and making the driver safer when driving; 2.It can effectively reduce the vibration of the body, and absorb some noise of the suspension system; 3.It can solve the spring weakness problem, the body will be raised by 0.2 to 0.3 cm, appropriate to improve the body.
