A steering lock for locking the steering spindle of a motor vehicle steering system including a blocking element that pivots along a longitudinal axis from a locking to an unlocking position using an electromechanical drive and is maintained in the unlocking position by a spring-loaded lever. In order to enable the lever to maintain the blocking element in the unlocking position when a worm drive generates the displacement of the blocking element, a worm gear representing a first control contour is used. A first cam for pivoting the blocking element to the unlocking position and a second cam for actuating the lever are mounted on the worm gear. Prior to the pivoting of the blocking element from the unlocking to the locking position, the lever is pivoted from a rest into a release position and, only afterwards, the worm gear enables the blocking element to pivot to the locking position.

Safe gear box for electrical steering column lock

An arrangement for locking the steering shaft of a motor vehicle, includes a blocking device and a toothed ring which is arranged on the steering shaft and in which a blocking element, which is arranged so that it can be displaced from an unlocked position into a locked position, of the blocking device engages. To allow the blocking device to be attached to the steering device of the vehicle in question and exchanged in a simple manner and to ensure that the blocking device cannot be removed in the locked state of the blocking element, the blocking device, which is provided with a housing, is releasably connected to a flange, which is attached to the steering device, via an adapter part. The flange has a recess which is designed in such a manner that the adapter part, for fitting of the blocking device, can be inserted in a partial area of the recess and can then be displaced along a guide into its limit position. Moreover, transverse webs are arranged between the teeth of the toothed ring, which webs, in the locked position of the blocking element, prevent axial displacement of the adapter part along the recess in the flange to the partial area.

Arrangement for electrically locking the steering shaft of a steering device

A compactly constructed locking device with a displaceable securing element fixing a detent element and actuated in a simple way into a detaining position or into a releasing position. The distance between a control cam and the securing element is selected in such a way that, with the detent element in the unlocking position, the control cam is axially displaced with respect to the control contour and is therefore located outside the range of action of the control contour. Only when the electromechanical drive is activated in order to displace the detent element into its locking position does the drive part with the control contour come into engagement with the control cam. The arrangement allows for sudden displacement into the locking position.

Locking device

A device ( ) for locking the steering spindle ( ) of a steering gear of a vehicle, having a blocking pin ( ) which is arranged in a housing ( ) and can be displaced from a release position into a locking position and vice versa. In order to prevent manipulation of the device ( ) by an unauthorized third party if the housing ( ) of the device ( ) has been forcibly opened and the blocking pin ( ) is located in its locking position, a spring-actuated securing element ( &prime;) is arranged in a guide part ( &prime;) of the blocking pin ( ), said securing element being fixed in its position by a closure element ( ) which is fastened on the inside of the housing ( ). If the housing ( ) is opened by an unauthorized third party, then the closure element ( ) is also removed together with the corresponding housing region and the securing element ( &prime;) is at least partially displaced into a recess ( ) of the blocking pin ( ) and secures the latter in its locking position.

Device for locking the steering spindle of a vehicle

A device for electrically locking the steering shaft of a motor vehicle steering device, which comprises an electric motor with actuator connected downstream, for displacing a blocking element which is arranged so that it can be displaced from its unlocked position into its locked position, and a switching device fore activating the electric motor. To ensure that the arrangement can be of very compact design and can be fitted without major changes in vehicles produced by different manufacturers, the invention proposes that the arrangement be composed of two separate subassemblies: a locking device with a first housing, in which the electric motor with actuator connected downstream and the blocking element is arranged, and manufacturer-specific electronic switching device, which can be attached o the outside of the first housing.
