Example Embodiment

[0029] The spindle drive 1 shown in the drawing is used for motorized adjustment of a door cover 2 of a motor vehicle, which is here configured as a tailgate. You can refer to the above-mentioned broad explanation of the concept of "door cover".

[0030] In its own conventional manner, the door cover 2 is used to close the door cover opening 3. Here, the spindle drive 1 is arranged laterally to the door cover opening 3, here and preferably, is arranged in the drainage groove 4 lateral to the door cover opening 3. figure 1 Although only a single spindle drive 1 is shown. However, here and preferably it is provided that the spindle drive 1 is arranged on both sides of the door opening 3 respectively. The two spindle drives 1 are constructed substantially identically in structure.

[0031] From the basis figure 1 It can be seen from the figure that the spindle drive 1 shown there is hinged at one end to the body 5 of the motor vehicle, and the other end is hinged to the door cover 2...

Abstract

The invention relates to a spindle drive for a flap (2) of a motor vehicle, which spindle drive can be moved between two drive end positions, in particular between a retracted position and an extendedposition, wherein two drive connections (6,7) for channelling drive movements and a drive train (8) between the drive connections (6,7) are provided, wherein the drive train (8) has a motor unit (9)and a drive screw mechanism (10) arranged downstream of the motor unit (9) in terms of drive, wherein the drive screw mechanism (10) has a spindle (11) with a spindle external thread and a spindle nut(12) with a spindle nut internal thread which is in screwed engagement with the spindle external thread, wherein a braking arrangement (13) for braking at least part of the drive train (8) of the spindle drive (1) is provided. It is proposed that the braking arrangement (13) can be adjusted in terms of its braking action (B) and that, for its adjustment, the braking arrangement (13) is coupled toa component (15) of the drive train (8).

Description

technical field [0001] The invention relates to a spindle drive for a door cover of a motor vehicle according to the preamble of claim 1 and to a door cover assembly of a motor vehicle according to claim 24 . Background technique [0002] At present, the concept "door cover" should be understood broadly. It includes, for example, tailgates, rear lids, bonnets, side doors, trunk lids, sunroofs, etc. of motor vehicles. In the following, the field of application of the motorized adjustment of a tailgate of a motor vehicle is presented. This should not be construed restrictively. [0003] Regularly, the spindle drive in question not only has the function of motorically adjusting the door flap, but also holds it in the open position (and, if necessary, in an intermediate position). For this purpose, the mentioned spindle drive is equipped with a brake assembly for braking at least a part of the drive train of the spindle drive and thus of the door cover. [0004] With the kno...
