I. What is an automotive control arm

The suspension system is an important part of modern automobiles, which has a great influence on the smoothness and handling stability of automobiles. As the guiding and force transmission element of the suspension system, the control arm transmits the various forces acting on the wheels to the body and ensures that the wheels move according to a certain trajectory. The arms are elastically connected to the wheel and body by ball hinges or bushings respectively. The automotive control arm (including the bushing and ball head connected to it) should have sufficient rigidity, strength and service life.

II. The structure of the control arm

When it comes to sourcing car suspension parts, quality matters, so it's important to find reliable car suspension suppliers that can provide durable components capable of withstanding the demands of different types of control arms. A clear understanding of the different types of control arms available can help ensure you choose the right parts for your specific needs.

1. Transverse stabilizer rod linkage

In the suspension installation, one end of the stabilizer bar link is linked to the transverse stabilizer bar through rubber bushings, and the other end is linked to the control arm or cartridge shock absorber through rubber bushings or ball hinges. The transverse stabilizer bar link is used symmetrically in the selector, and its role is to improve the operating stability.

2. Transverse tie rod

In the suspension installation, the rubber bushing at one end of the cross tie bar is connected with the frame or body, and the rubber bushing at the other section is connected with the wheel hub. This kind of control arm is mostly used in the multi-link suspension of the car and the cross tie bar of the steering system, which mainly bears the lateral load and guides the wheel movement at the same time.

3. Longitudinal tie rod

Longitudinal tie rods are mostly used in towing suspensions to transmit traction and braking force.

4. Single control arm

This kind of automobile control arm is mostly used for multi-link suspension, and two single control arms are used together to transmit the transverse and longitudinal loads from the wheels.

5. Fork (V)-shaped arm

This kind of automobile control arm is mostly used for the upper and lower arms of double wishbone independent suspension live MacPherson suspension lower arm, the fork-shaped structure of the arm body mainly transmits the transverse load.

6. Triangular arm

This kind of car control arm is mostly used for the lower arm of the front suspension MacPherson suspension, used to transfer the transverse and longitudinal loads, and control the relative motion of the wheels and the body.
