Abstract: The invention relates to a locking device (70), in particular a steering wheel lock (70), for a vehicle, for a functionally-essential component (74), in particular in the form of a steering column or a gearshift lever or the like, having at least one manually actuable, in particular rotatable, operating part (10), wherein at least two rotational positions (0, III) can be assumed by the operating part (10), namely an off position (0) and a start position (III), wherein in the off position (0), at least one engine of the vehicle can be turned off and/or the functionally-essential component (74) can be fixed by a blocking pin (71) in a locked position, and in the start position (III), at least one consumer, in particular a starter of the vehicle can be turned on and/or the functionally-essential component (74) can be released by a blocking pin (71) in an unlocked position.

Abstract: A gear unit having a drive element with a first tooth structure, an output element with a second tooth structure, wherein the tooth structures are able to be brought into engagement cogging with each other to form a gearing in at least one engagement area of the second tooth structure. The output element has at least one uncoupling area, in which the cogging engagement of the gearing is uncoupled. The first tooth structure has at least one first modified tooth element and the second tooth structure has at least one second modified tooth element wherein by a movement of the drive element, synchronization of the second modified tooth element with the first modified tooth element is possible in order to create a change from the uncoupled state to the engagement state.

Abstract: The invention relates to a locking device for the locking and/or unlocking of a component essential for the function of a vehicle with a casing, which more preferably serves for the fastening of the locking device to the component essential for the function and a moveable locking member, which can assume at least two positions, namely a locking position, in which the locking member protrudes from the casing through an opening and is actively connected with the component essentially for the function and an unlocking position, in which the locking member is not actively connected with the component essential for the function and an arresting part which in an arresting position arrests the locking member in the locking position in the event that the locking device is opened without authorization. To this end it is provided according to the invention that the arresting part is positively held in the arresting position.

Abstract: The invention concerns a gear unit (1) having a drive element (10) with a first tooth structure (11), an output element (20) with a second tooth structure (21), wherein the tooth structures (11, 21) are able to be brought into engagement cogging with each other to form a gearing in at least one engagement area (X) of the second tooth structure (21), and wherein the output element (20) has at least one uncoupling area (Y), in which the cogging engagement of the gearing is uncoupled. The invention provides that the first tooth structure (11) has at least one first modified tooth element (11a) and the second tooth structure (21) has at least one second modified tooth element (21a), wherein by a movement of the drive element (10), synchronization of the second modified tooth element (21a) with the first modified tooth element (11a) is possible in order to create a change from the uncoupled state to the engagement state.

Abstract: A device for blocking the steering shaft of a motor vehicle against rotation by a locking bolt which can be axially moved back and forth between locked and released positions via a two-directionally rotatable control member, and comprises a locking element and an actuating element. The control member surrounds the actuating element and has two helically extending interior grooves and a planar end surface adjoining the grooves and extending perpendicular to the axis of rotation of the control member. A transverse pin axially displaced in the actuating element cooperates with the grooves and the end surface. A helical compression spring is supported on the actuating element via a plunger having an oblong hole through which the transverse pin extends, and which plunger can be axially displaced in the actuating element by a stop so that the helical compression spring presses the transverse pin against the end surface via the locking element and the actuating element in the released position of the locking bolt.

Abstract: Disclosed is a device for blocking the steering shaft (1) of a motor vehicle against rotation by means of a locking bolt (2) which can be axially moved back and forth between a locked position and a released position in a housing (10) via a two-directionally rotatable control member (34) and comprises a locking element (6) and an actuating element (7). The control member (34) surrounds the actuating element (7) and is provided with two interior grooves (42, 43) that extend in a helical manner and a planar end surface (44a, 44b) which adjoins the grooves and extends perpendicular to the axis of rotation (11) of the control member (34). A transverse pin (40) which can be axially displaced in a transverse bore (41) of the actuating element (7) cooperates with said grooves (42, 43) and said end surface (44a, 44b). The locking element (6) can be pushed into the actuating element (7) against the action of a helical compression spring (8).

Abstract: Disclosed is an electronic steering wheel lock for motor vehicles, comprising a rotor (5) that is rotatable within a stator (2) from an initial position and back into said initial position so as to move a locking member (3) back and forth between a steering shaft-locking position and a steering shaft-releasing position. In its initial position, said rotor (5) can be coupled in a positive manner to the stator (2) under the effect of a spring load (22) while being movable within the stator (2) in an axial direction against the effect of the spring load (22) by means of an electromagnet (7) disposed coaxially to the rotor (5) in order to cancel the mutual engagement between the rotor (5) and the stator (2) and allow the locking member (3) to be moved into the steering shaft-releasing position when the electromagnet (7) is excited with the aid of an electronic key. The rotor (5) is provided with at least one coupling dog (23) which cooperates with a coupling slot (24) of the stator (2).
