Embodiment Construction

[0028] The drive assembly 1 shown in the figures is used for motor adjustment of a rear cover 2 of a motor vehicle. At least one drive 3 , 4 is provided in order to generate the drive power required for this. Here and preferably two drives 3 , 4 are provided, which each have two drive couplings 3 a , 3 b , 4 a , 4 b for discharging drive power. The drive couplings 3a, 3b, 4a, 4b are figure 1 In the installed state shown in , it is connected to the rear cover 2 in terms of drive technology. For this purpose, in the case of the embodiment shown and preferred in this respect, the drive couplings 3a, 3b, 4a, 4b are each part of a ball stud-ball-socket-bearing.

[0029] Of the two drive sections 3,4 in figure 1 center on the left and in figure 2 The first drives 3, 4 shown in a) are motor- and spring-driven and accordingly have a drive motor 5 and a drive spring 6, which act respectively on two drive couplings 3a, which are associated with the first drive 3, 3b.

Abstract

The invention relates to a drive arrangement for the motorized movement of a tailgate of a motor vehicle, wherein at least one drive unit is provided, having two drive connections for channeling out drive unit power, wherein a first drive unit is motor and spring-operated and has a drive unit motor as well as a drive unit spring, respectively acting on the two drive connections associated with the first drive unit, wherein the first drive unit comprises a movement sensor for generating a sensor signal, representing movement information regarding a movement between the drive connections of thefirst drive unit, wherein a second drive unit is solely spring-operated and has a drive unit spring, acting on the two drive connections associated with the second drive unit, wherein a drive unit controller is provided, which detects a predetermined deviation of the sensor signal of the movement sensor from a predetermined normal signal corresponding to the normal condition as an error conditionand upon detecting an error condition carries out an error routine.

Description

technical field [0001] The invention relates to a drive assembly according to claim 1 for motorized adjustment of a rear lid of a motor vehicle and a rear lid assembly according to claim 12 with such a drive assembly. Background technique [0002] The rear lids of motor vehicles are increasingly equipped with the mentioned drive assemblies in order to provide motor adjustment of the rear lid between a closed position and an open position. [0003] It is basically known to mount a purely motor-driven drive with a purely spring-driven drive in order to reduce the required motor power and thus cost. The purely spring-driven drive, which is often constructed as a gas spring, usually counteracts the weight of the rear cover. [0004] Depending on the often large weight of the back cover, a sudden stop of the drive part of the drive assembly (currently also referred to as "interruption of the drive part") can lead to undesired surprises of the back cover. This results, for examp...
