Embodiment Construction

[0024] figure 1 A partial view of a microdrive 1 is shown, wherein a gear 3 with a worm gear 4 is arranged in a lock housing 2 . Only the mechanical locking device 5 is shown here, in particular in the form of an elastic lip 30 which will be described later.

[0025] figure 2 and image 3 An embodiment of the locking device 5 in the form of a mechanical locking element 8 is shown, which consists of a clamping wheel 10 and a drive wheel 11 cooperating with it. The drive wheel 11 and the clamping wheel 10 are connected via an overrunning clutch 12 which will be described below.

[0026] exist figure 2 In the illustration in , the clamping wheel 10 and the drive wheel 11 are moved in the drive direction 7 , ie the microdrive 1 releases the vehicle lock (not shown in detail here). In this case, the drive wheel 11 , via its cam 18 , drives the clamping wheel 10 , which has protruding spring arms 16 , 17 . The spring arms drag on the inner side 14 of the ring part 15 shown. ...

Abstract

The invention relates to a microdrive (1) for use in a vehicle lock. After the opening process and after the motor has stopped running to prevent the transmission (3) from reversing, in particular a mechanically acting locking element (8) is assigned to the worm wheel, which firstly provides for the unlocking and loss of the transmission (3) Minor reversals are allowed under load, however further rotation against the drive direction (7) is then prevented.

Description

technical field [0001] The invention relates to a micro-driver for actuating a vehicle lock. The micro-driver has a motor and a transmission device with a worm wheel arranged in a lock housing. The micro-driver has a locking device for preventing the transmission device from reversing. Background technique [0002] In drives for electrically opening vehicle locks, in particular micro drives, the electric motor is energized in such a way that it can only drive the transmission with the worm gear in one direction, especially for cost reasons. Resetting of the transmission after the end of the motor energization is undesirable and may prevent continued operation of the microdrive. Since the known transmission is supported—at least in part—by a spring, a reset of the worm wheel of the transmission is brought about without a locking device after the current has been switched off and the drive has been switched off. As mentioned, this is disadvantageous and undesirable. In gener...
