[0002] During the production and assembly of vehicle components, the existence of tolerances may lead to assembly difficulties between two vehicle components. In order to cope with this situation, tolerance adjustment devices are added when assembling two vehicle components.

The tolerance compensation is achieved through the connection between the three. However, it can only be used for tolerance compensation in the axial direction of the fastening bolt, and cannot be used for radial tolerance compensation perpendicular to the axial direction of the fastening bolt. There are certain limitations, and therefore, further improvements are needed. In addition, some types of part gap compensation devices are difficult to disassemble and need to be disassembled by destroying the part gap compensation device.
