Embodiment Construction

[0023] exist figure 1 The drive assembly shown in is used for motorized adjustment of a rear hatch 1 of a motor vehicle. However, all other adjustment elements mentioned in the introductory part of the description can also be used to advantage. All the embodiments described below for the rear panel correspondingly apply equally to all the other adjustment elements mentioned there.

[0024] exist figure 1 The drive assembly shown in is associated with two identical drives 2 each having a drive motor 3 . The drive 2 is arranged in both lateral regions of the rear hatch opening 4 . exist figure 1 Only one of these two drives 2 is shown in . figure 2 The drive 2 is shown in side view. The following implementation only deals with figure 1 Recognized drive 2 in . However, the same applies to additional drives which may be present.

[0025] The drive motor 3 is preferably a DC motor. However, it is also conceivable to use an AC motor here.

[0026] Furthermore, the drive ...

Abstract

The invention relates to a drive assembly for the motorized adjustment of an adjusting element (1) of a motor vehicle, wherein at least one drive (2) with an electric drive motor (3), in particular a DC motor, and the drive (2 ) associated and connected to a power source (V) with a power supply voltage UV, in particular the vehicle battery, of the drive controller (5), wherein the drive (2) is designed as non-self-locking so that at the regulating element (1) The drive motor (3) operates as a generator and generates a generator voltage UG in non-motorized regulation of the drive controller (5) having a drive unit (6) for supplying the at least one drive (2) with electrical drive power . It is proposed that the drive controller (5) has a switching device (7) for switching the supply voltage (UV) to the drive unit (6) and a detection device (8) for detecting a non-motorized adjustment of the adjusting element (1) , and the drive controller (5) switches the supply voltage (UV) to the power supply of the drive unit (6) during the switching process by means of the switching device (7) when detecting a predetermined non-motorized adjustment of the adjusting element (1) connections (9, 10) so that the drive motor (3) works as a generator for the power supply (V) and is correspondingly braked.

Description

technical field [0001] The invention relates to a drive assembly for the motorized adjustment of an adjusting element of a motor vehicle according to the preamble of claim 1 and to an adjusting element assembly of a motor vehicle according to claim 15 . Background technique [0002] The term "regulatory element" should now be interpreted broadly. These include tailgates, rear lids, engine hoods, doors, in particular side doors, cargo compartment floors, etc. of motor vehicles. [0003] Firstly, the drive unit in question is used, however, in side doors and tailgates in motor vehicles. It serves for the motorized adjustment of the respective adjusting element in the closing direction and in the opening direction. It is generally important here that the drive assembly also permits a manual adjusting operation in addition to a motorized adjusting operation. Manual adjustment operations are especially important in emergency situations, for example in the event of a collision ...
