suspension arm

A control arm's purpose is straightforward. It connects the steering knuckle to the frame and stabilizes the vehicle by allowing the chassis and the wheels to move in unison while the vehicle is in motion

They help form a connection between control arms and steering knuckles. This provides smooth movement within the suspension. Ball joints allow the steering knuckles to move in different directions while ensuring they remain attached to the vehicle.

Suspension bushing can reduce the impact and vibration transmitted to the body; At the same time to ensure the vehicle handling stability, ensure the suspension of the elastic kinematic characteristics; There is only one kind of rubber bushing, and its stiffness should be compromised between operating stability and smoothness;

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. Ball head of the control arm is made of carbon steel; 2. The ball-type connection is used to achieve different coaxial power transmission, providing multi-angle rotation, so that the steering mechanism can smooth steering, reduce vibration and achieve smooth steering;
