What Causes the Noise from the Door Stopper?

[DiKarter]

The hinge axis of the car door and the rotation axis of the stopper are severely misaligned. Here are the detailed explanations: 1. Causes of noise from the door stopper: The function of the door opening limiter (Doorcheck) is to restrict the degree to which the door can open. It limits the maximum opening of the door, preventing it from opening too wide, and keeps the door open when needed, such as when the car is parked on a slope or in moderate wind, so the door does not close automatically. Common door opening limiters are separate strap-type limiters, while some limiters are integrated with the door hinge, typically providing limiting functions when the door is fully or partially open. 2. Precautions: Ensure that the friction surface of the limiter is lubricated. The misalignment issue between the door hinge axis and the stopper rotation axis can also be resolved through adjustment, but this requires higher technical skills and is often solved based on experience. Therefore, it is best to ensure this during the design and manufacturing process, and positioning aids should be used during installation.
