Description

The invention relates to a device for compensating for tolerances between two components to be joined together. Such a tolerance compensation device is generally known and is used, for example, in vehicle manufacturing, particularly when it comes to bolting two components together across a gap with tolerances. For this purpose, the tolerance compensation device is positioned between the components to be joined, and a screw element for fastening the components, such as a screw or a threaded bolt, is guided through appropriately provided openings in the components and through the tolerance compensation device. When the screw element is tightened, the compensation element is rotated relative to the base element by a drive spring located between the screw element and the compensation element. This causes it to move axially from its initial position to the base element, for example, extending out of the base element, until it reaches its compensation position. In this position, the base element and the compensation element each rest against one of the components, thus bridging the gap. For example, from the DE 298 10 172 U1 A device for connecting components is known, comprising a connecting screw and two spacer rings surrounding the connecting screw that can be rotated relative to each other and which support each other in the axial direction via helical stiffening surfaces. The object of the present invention is to provide a device for compensating for tolerances between at least two components to be joined together, which is improved compared to the prior art. The problem is solved by the features specified in claim 1. Advantageous embodiments of the invention are the subject of the dependent claims. The problem is solved by a device according to the invention for compensating for tolerances between at least two components to be connected to one another by means of a screw element, wherein the device comprises at least one base element, a first compensating element connected to the base element, in particular in engagement, for example in thread engagement, and a second compensating element connected to the first compensating element or to the base element, in particular in engagement, for example in thread engagement, and wherein the first compensating element and the second compensating element can each be moved from a starting position to a compensating position by rotation relative to the base element and relative to each other. In particular, the compensating elements and the base element are designed to be telescopically movable relative to each other and/or within each other. The advantages achieved with the invention consist in particular of the fact that, by means of such a nested and/or telescopic arrangement of the base element and the compensating elements, the device can be designed to be comparatively small and compact, while still being able to compensate for comparatively large tolerances between at least two components. Furthermore, no compensation path, in particular the tolerance compensation path, of the device needs to be shortened to achieve a comparatively smaller and more compact design. The device is, for example, a tolerance compensation device, particularly for compensating for tolerances when attaching a component to a part with a bore or blind hole. Tolerance compensation devices are part of fasteners used to fasten components and parts to each other, for example in motor vehicles. Such tolerance compensation devices are, for instance, pressed into one of the parts. In particular, the device is an automatic tolerance compensation system. In one possible embodiment, the first compensating element is arranged on a first end face of the base element. The first compensating element can be adjusted relative to the base element to compensate for tolerances between two components. The first compensating element is axially movable relative to the base element. The first compensating element is movably arranged in a cavity of the base element. The first compensating element can be designed as a hollow cylindrical compensating element that engages or can be brought into thread engagement with a base element, and which can be axially moved from the initial position to a compensating position by rotating it relative to the base element. In one possible embodiment, the second compensating element is arranged together with the first compensating element on the first end face of the base element. The second compensating element can be adjusted relative to the first compensating element and to the base element to compensate for tolerances between two components. The second compensating element is axially movable relative to the first compensating element and to the base element. The expansion directions of the compensating elements are the same. Both expansion directions correspond, for example, to an upward or downward movement out of the base element. The first compensating element and the seco
