Abstract

The present invention relates to a drive arrangement having a hinge which comprises a first hinge arm and a second hinge arm which can be rotated with respect to the first hinge arm about a hinge axis, wherein the first hinge arm is arranged by means of a bolt on a support means which is provided to support a torque when the hinge arms are rotated relative to one another, in that the bolt engages through an aperture in the first hinge arm and is fixed by means of an elastic press fit in a through-hole of the support means. The present invention additionally relates to a motor vehicle having such a drive arrangement, to a bolt for such a drive arrangement, and to a method for mounting the drive arrangement.

Claims

1. A drive arrangement (10) for a rotatable flap, with a hinge which has a first hinge arm (5.1) and a second hinge arm (5.2) rotatable with respect to the first hinge arm (5.1) about a hinge axis (5.3), wherein the drive arrangement (10) comprises a support means (4) on which a bolt (3) which reaches through a recess (5.1.1) in the first hinge arm (5.1) is arranged, characterized in that the bolt (3) is secured by an elastic press fit in a through-hole (4.1) of the support means (4).

2. The drive arrangement (10) as claimed in claim 1, characterized in that the through-hole (4.1) has a direction of extent (X), wherein said through-hole is elastic in a Y direction (Y) transverse to the direction of extent (X).

3. The drive arrangement (10) as claimed in claim 1, characterized in that the through-hole (4.1) is an elongated hole.

4. The drive arrangement (10) as claimed in claim 1, characterized in that a notch (4.11) is provided on the through-hole (4.1).

5. The drive arrangement (10) as claimed in claim 1, characterized in that the support means (3) is an insertable panel.

6. The drive arrangement (10) as claimed in claim 1, characterized in that the bolt has a cylindrical region (3.3) which has a diameter (d) which is larger than a height (hy) of the through-hole (4.1).

7. The drive arrangement (10) as claimed in claim 6, characterized in that the bolt (3) has a threaded region (3.1) with a thread (3.11), wherein an outside diameter (d1) of the bolt (3) in the threaded region (3.1) is smaller than the height (hy) of the through-hole (4.1).

8. The drive arrangement (10) as claimed in claim 7, characterized in that a conical region (3.2) widening in a fitting direction (6) is provided between the threaded region (3.1) and the cylindrical region (3.3).

9. The drive arrangement (10) as claimed in claim 8, characterized in that a diameter (d2) of the conical region (3.2) at a transition (3.23) to the cylindrical region (3.3) is approximately equal to that of the cylindrical region (d3).

10. The drive arrangement (10) as claimed in claim 7, characterized in that a length (h1) of the threaded region (3.1) is greater than the depth (t) of the support means (4).

11. The drive arrangement (10) as claimed in claim 1, further comprising a stop (3.4) for the support means (4).

12. The drive arrangement (10) as claimed in claim 1, further comprising an adjustment drive (1) for automatic rotation of the second hinge arm (5.2), wherein the second hinge arm (5.2) is arranged on a drive lever (2) which is arranged on an output shaft (1.1) of the adjustment drive (1) for conjoint rotation.

13. A motor vehicle with a rotatable flap, having a drive arrangement (10) as claimed in claim 1.

14. A method for mounting a drive arrangement (10) as claimed in claim 12, with the following steps:

pushing the adjustment drive (1) in a fitting direction (6) onto the hinge until the bolt (3) passing through the recess (5.11) of the first hinge arm (5.1) lies against the through-hole (4.1) of the support means (4),

screwing a nut (7) onto the bolt (3) until the support means (4) lies against a stop (3.4), and

securing the second hinge arm (5.2) on the drive lever (2).
