Embodiment Construction

[0020] The screw drive 1 shown in the drawing is used to electrically adjust a motor vehicle flap 2 , which here is formed by the rear lid. Please refer to the description above regarding the term "clamshell".

[0021] Back cover 2 is generally used for closing back cover hole 3, and wherein screw drive device 1 is arranged on the side of back cover hole, preferably is arranged on the inside of rain gutter 4 laying on back cover hole 3 sides here. and figure 1 Only a single screw drive 1 is shown. However, it is preferably provided here that a screw drive 1 is arranged on each side of the rear cover opening 3 . The two screw drives 1 are substantially identical in structure.

[0022] according to figure 1 It can be seen that the screw drive shown there is hinged at one end to the vehicle body 5 and at the other end to the rear cover 2 . The screw drive 1 advantageously has only a slight length, which is given by the proposed construction of the screw drive.

Abstract

The invention relates to a spindle drive for a valve (2) of a motor vehicle, comprising a motor drive arrangement (6), comprising a spindle gear mechanism (7) drivingly connected downstream of the motor drive arrangement (6), and comprising two drive connections (8, 9) for transmitting drive movements. The spindle gear mechanism (7) has a spindle (10) which can be rotated by the motor drive arrangement (6) and a spindle nut (11) which is engaged with the spindle in a rotationally fixed manner. The spindle nut (11) carries out an axial retraction movement (12), in which the distance between the two drive connections (8, 9) is reduced, and an axial extension movement (8, 9), in which the distance between the two drive connections (7, 8) is increased, according to the rotational direction of the spindle (10). The spindle nut thread (11a) extends beyond the spindle thread (10a) in the direction of the retraction movement (12) at least in the fully retracted position and surrounds at least one part of the motor drive arrangement (6).

Description

technical field [0001] The invention relates to a screw drive for a motor vehicle flap according to the preamble of claim 1 and to a motor vehicle flap device according to claim 14 . Background technique [0002] The term "flip" is used generically herein. This includes, for example, tailgates, rear lids, hoods, side doors, cargo lids, lift roofs or similar structures of motor vehicles. The following area of ​​application is based on the electrical adjustment of the rear lid of a motor vehicle. This is not to be understood as a limitation. [0003] In recent years, the use of screw drives for electrically adjusting tailgates has gained increasing significance. In addition to a high degree of operational reliability, the highest possible level of comfort is a constant requirement. [0004] The invention originates from the known screw drive (DE 10 2008 062 391 A1) with a motor drive and a screw drive downstream of the motor drive. A screw extending on the main axial sect...
