Embodiment Construction

[0029] The spindle drive 1 shown in the drawing is used for the motorized adjustment of a door flap 2 of a motor vehicle, which is designed here as a tailgate. See above for a broad explanation of the concept "door cover".

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

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

[0032] The spindle drive 1 can be adjusted ...

Abstract

The invention relates to a spindle drive for a door cover (2) of a motor vehicle, which can be adjusted between two drive end positions, in particular between a retracted position and an extended position, wherein , two drive interfaces (6, 7) are provided for deriving the drive movement and a drive train (8) is arranged between the drive interfaces (6, 7), wherein the drive train (8) has a motor unit ( 9) and the drive-screw drive (10) connected technically behind the motor unit, wherein the drive-screw drive (10) has a spindle (11) and a spindle nut (12), the spindle has a spindle-external thread, the spindle nut has a spindle nut-internal thread, the spindle nut-internal thread engages with the spindle-external thread, wherein the device for braking the spindle drive (1) is provided A brake assembly (13) for at least a portion of the drive train (8). It is proposed that the brake assembly (13) is adjustable with respect to its braking action (B), and that the brake assembly (13) is coupled to a component (15) of the drive train (8) for to adjust it.

Description

technical field [0001] The invention relates to a spindle drive for a door cover of a motor vehicle and to a door cover assembly of a motor vehicle. 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 known spindle drive (DE202011106110U1), the brake assembly is o...
