Background
After the vehicle door limiter is installed, the friction state of a main arm in contact with an internal sliding block is inconsistent in the using process, and the specific summary is basically divided into two situations.
The first is that the main arm is contacted with the upper and lower sliding blocks at two sides respectively, wherein friction traces at one side are few, and traces at the other side are distributed over the full stroke, even the abrasion condition occurs; the second is that on the surface of the same side of the main arm, the friction conditions at two sides are not consistent, and the phenomenon that one side is more and the other side is less occurs. The long-time friction can cause the abnormal sound of opening and closing the door, can seriously make stopper function lose (can't play limiting displacement).
After the whole vehicle is assembled, the relative position of the vehicle door and the side wall is ensured through the hinge and the door lock, and the relative clearance and the surface difference can only be evaluated by the integral state. The position of the limiter relative to the car door end and the side wall end is detected by a proper tool, and the position of the limiter is ensured only by the self-precision of each mounting hole. In practice, however, the main arm of the stopper and the base are deformed relatively and always exist along with the vehicle due to tolerance accumulation and moment tightening during installation.
