Embodiment Construction

[0021] A motor vehicle drive is shown in the drawing. In this case, the motor vehicle drive is installed in the housing 1 of the motor vehicle door lock. This is exemplary only and by no means restrictive.

[0022] exist figure 1 The motor vehicle door lock with housing 1 shown in , has inside it conventional components such as release lever 2 and pawl 3 as components of a locking mechanism not shown in detail. The motor vehicle drive has an electric motor 4 and a transmission element 5 which is driven indirectly or directly by means of the electric motor 4 .

[0023] In the exemplary embodiment, the electric motor 4 is used to directly drive the transmission element 5 . For this purpose, the electric machine 4 has an output worm 6 on the output shaft on the output side, which meshes with a toothing (not shown in detail) on the transmission element 5 designed as a worm gear. In this way the worm gear can surround it in the figure 1 The shaft 7 shown in figure 1 as indica...

Abstract

The invention relates to a motor vehicle drive equipped with an electric motor (4) and at least one transmission element (5) indirectly or directly driven by the electric motor. Furthermore, a spring (9) is assigned to the transmission element (5), which spring is provided for resetting the transmission element (5) bidirectionally. According to the invention, the spring (9) is designed as a spiral spring (9), which is designed to be wound both from the inner spring leg (9a) and from the outer spring leg (9b) and loose rolls.

Description

technical field [0001] The invention relates to a motor vehicle drive, which has an electric motor and at least one transmission element driven indirectly or directly by the electric motor, and has a spring associated with the transmission element, which spring is arranged for the transmission The element resets bidirectionally. Background technique [0002] Motor vehicle drives are widely used in motor vehicles. Examples of this are mirror adjustments, seat adjustments, window regulators, and unlocking devices on the bonnet, hatch etc. Furthermore, motor vehicle drives of this type are increasingly used in connection with locking and unlocking devices for charging plugs in corresponding receptacles of electric vehicles. Particularly preferably within the scope of the present application are motor vehicle drives which are used in combination with a motor vehicle door and are used here in particular in connection with a motor vehicle door lock. [0003] Such motor vehicle ...
