Embodiment Construction

[0044] figure 1 An electrically operated rear liftgate 2 is shown, which has a hinged lid 6 mounted pivotably about a pivot axis 4 , by means of which the trunk (not shown) of the motor vehicle is covered. For this purpose, the flap 6 can be brought about the pivot axis 4 in the pivot direction 8 to a stop 10 which is formed by the body. In this case, the flip cover 6 is brought up to the stop 10 when opening, for example. In other words, the stop 10 limits the opening movement of the flip cover 6 . For automatic opening and closing of the flap 6 , the electrically operated rear flap 2 comprises a drive unit 12 having a first drive chain 14 and a second drive chain 16 . The screw mandrel 18 of the first driving chain 14 is connected with the flip cover 6 at the first position 20, and the screw mandrel 22 of the second drive chain 16 is connected with the flip cover 6 at the second position 24, wherein, two positions 20, 24 lie in a horizontal plane and are spaced apart from...

Abstract

The invention relates to an adjusting drive (2) of a motor vehicle, in particular an electrically operated tailgate, which has an adjusting part (6) and a drive chain with a first drive chain (14) and a second drive chain (16). drive unit (12). Each drive chain (14, 16) has a variable length servo section (18, 22) connected to the adjustment section (6), the servo section being powered by the electric motor (28, 30) of the respective drive chain (14, 16) drive. The first drive chain (14) has at least one sensor (52) for detecting the positioning of the rotating part (54), and the second drive chain (16) has at most one sensor for detecting the positioning of the rotating part (58) ( 56). The invention also relates to a drive unit (12) of an adjusting drive (2) of a motor vehicle.

Description

technical field [0001] The invention relates to an adjusting drive of a motor vehicle having a drive unit with a first drive chain and a second drive chain. Tail flap for adjusting drives especially for electric operation. The invention also relates to a drive unit of an adjusting drive. Background technique [0002] Motor vehicles usually include adjustment parts, such as side windows and / or sliding sunroofs, which can be opened or closed by means of an electric adjustment drive. The respective adjustment part is actuated by means of a transmission driven by an electric motor, which in particular comprises a spindle. In order to adjust the drive speed of the regulating section, the electric motor is operated with pulse width modulation (PWM) and thus regulates the delivered electrical energy. In order to reduce the production costs of the control device required for this purpose, the direction reversal of the regulating part is effected by means of a bridge circuit. In ...
