The suspension arm (also known as control arm) in a BMW, like in other vehicles, is a critical component of the suspension system. It connects the chassis of the vehicle to the wheels, allowing the suspension to move up and down while keeping the wheels aligned with the body of the car. In BMWs, suspension arms come in various designs, including upper and lower control arms, and they are made of high-quality materials to ensure durability and precise handling.
Functions of the Suspension Arm (Control Arm)
-
Connects the Wheel to the Chassis:
- The suspension arm allows the wheel to move vertically while keeping it properly aligned with the body of the car.
-
Controls Suspension Movement:
- It helps in controlling the movement of the suspension, allowing the wheels to absorb bumps and keep the ride smooth.
-
Maintains Alignment:
- Suspension arms play a key role in maintaining proper wheel alignment, which affects the handling, tire wear, and overall performance of the vehicle.
-
Transfers Force from the Wheel:
- The suspension arm transmits forces from the wheel and tire to the car’s body, allowing the suspension to absorb shock and maintain stability.
