Control arms or Control links are critical safety components of a vehicle suspension system, primarily manufactured for the rail vehicles to support axle location and to resist braking & traction forces. It can also be used in other industries vehicle suspension systems like Automotive, Off-highway etc.

What are Control Links or Control Arms?

Control links or Control arms link the vehicle chassis & suspension hub that carry the wheel. These are the important component of a vehicle suspension system that allows wheels to move in line with the vehicle body. In the rail industry, it helps the bogie to safely negotiate the curved track. Generally, they are made up of three major components.

Components of Control links:

The primary parts of the control links are:

  1. Bushing
  2. Ball joint
  3. Link

The bushings are usually rubber or rubber to metal bonded bushings and they help to connect the body of the control links to the frame of the vehicle. It also helps to reduce the noise. However, the ball joint helps to connect the body to the wheel side of the suspension of the vehicle. So when the parts are combined and work together, they ensure a smooth and controlled movement of the vehicle, especially when turning, pivoting, and driving on the road. They allow the wheels to move up and down while ensuring stability by keeping contact with the ground. When steering, the control arms also minimize vibration and friction.

Control Links are usually made of steel, aluminum, or cast iron depending upon the application and customer requirements.
