Definitions
- the present invention is directed to a mechanical lock cylinder for at least one ignition switch or steering lock in a vehicle according to the preamble of claim 1.
- Such lock cylinders are mechanically complex components which have a cylinder core which is at least rotatably mounted in a cylinder housing. Furthermore, at least one blocking element is provided in the cylinder core, which prevents rotation of the cylinder core in the cylinder housing in a blocking position and releases a rotation in the cylinder housing in a release position, provided that a suitable key is used.
- a key channel is provided, in which the key with its key bit is inserted and with which the locking member between the locking position and the release position is movable, wherein at least two rotational positions are ingestible by the cylinder core, namely an off position and a start Position, with a key in the key channel on and off in the off position is executable and in the start position, at least one consumer, in particular a starter, of the vehicle is switched on.
- the present invention is also directed to a steering wheel lock for blocking a functionally essential component of the vehicle according to the preamble of claim 17.
- a functionally essential component here is a steering wheel or a gear lever conceivable.
- the present invention is also directed to a method for operating a lock cylinder or a steering wheel lock according to the preamble of claim 20.
- lock cylinders for motor vehicles are known from the prior art, such. B. from the publication DE 203 21 590 U1.
- Such lock cylinders can be used in a vehicle in the region of the door handles for locking and unlocking a door or a central door lock as well as a steering wheel lock.
- increased security is required because quickly operating errors by the driver can lead to unwanted electrical and / or mechanical switching states in the vehicle, which can then cause an accident.
- So z. B. lead by an unintentional adjustment of the lock cylinder in an off position cause all electrical consumers of the vehicle are turned off, such.
- the power steering, brake booster, an antilock brake system and so on As well as the engine, the power steering, brake booster, an antilock brake system and so on.
- the object of the present invention is therefore to provide a lock cylinder for at least one ignition switch or a steering wheel lock in a vehicle and a steering lock for a vehicle as well as an operating method for a lock cylinder or a steering lock, which has an increased safety, in particular reliability in addition to break-in security, features. It is in particular an object of the invention, the handling of the lock cylinder and the Steering wheel lock and the corresponding operating method as simple as possible but secure.
- the present object is achieved by a lock cylinder for at least one ignition switch or a steering wheel lock in a vehicle having the features of claim 1, in particular from the characterizing part. Also to solve the problem, a steering wheel lock for blocking a functionally essential component in a vehicle having the features of claim 17, in particular from the characterizing part, is achieved. Also, a method for operating a lock cylinder or a steering wheel lock in a vehicle with the features of claim 20, in particular from the characterizing part proposed to solve the problem. In the dependent device and method claims preferred developments of the invention are listed. Features that are disclosed to the lock cylinder according to the invention, also apply to the steering wheel lock according to the invention and the method according to the invention and in each case vice versa.
- the features of the steering wheel lock according to the invention for the method according to the invention and vice versa so that between the individual aspects of the present invention, respectively mutually referred to.
- the lock cylinder according to the invention for the steering wheel lock according to the invention can be used and the inventive method can be carried out with it.
- a return lock is provided which prevents a provision of the cylinder core at least from the start position to the off position by a simple rotation of the cylinder core.
- reset lock can be a purely mechanical or electro-mechanical reset lock, in particular the provision of the cylinder core in the cylinder housing positively and / or non-positively blocked. This prevents that can take place by an unwanted, simple rotation of the cylinder core the off position and thus the shutdown of the engine and other electrical consumers and possibly even blocking a steering shaft or other functionally essential component.
- the return lock is a provision of the cylinder core from a travel position in the off position, in particular in an ACC position, prevented by a simple rotation of the cylinder core. What this means is that an exclusive rotation of the cylinder core just not enough to turn the cylinder core from its drive position to the ACC position or beyond in the off position back. Rather, a deliberate actuation of the reset lock must be made by the driver.
- the return lock prevents a return of the cylinder from a drive position to the off position by a particular exclusive rotation of the cylinder core. This means that a simple rotation of the cylinder core in the off position just is not possible.
- the cylinder core has at least three stable rotational positions, namely an OFF position, an ACC position, and a driving position. Having position in which the cylinder core is fixed by a fixing element in particular non-positive and positive.
- This fixing can be designed, for example, as a ball catch and interact directly with the cylinder core to fix the cylinder core in the aforementioned stable rotational positions, from which the cylinder core can be rotated only by a slightly increased force on the key in the next rotational position.
- the fixing element can also be provided in a downstream ignition starting switch, which then generates the stable rotational positions of the cylinder core. A corresponding ignition starter switch can be easily brought into mechanical engagement with the lock cylinder via a coupling element.
- the cylinder core has at least one unstable rotational position, namely a start position, which can only be achieved against an acting additional rotational force.
- This set to rotational force can permanently act on the unstable rotational position to transfer the cylinder core of this unstable rotational position in the nearest, especially driving position. This also ensures that the cylinder core can not accidentally get from the drive position to the start position.
- start-up repeat lock which prevents the cylinder core from being able to be transferred directly from the drive position into the start position more than once, ie exactly once .
- the start position is used in a vehicle to start the starter for the internal combustion engine.
- the starter must be turned off to avoid damage.
- the lock cylinder prevents re-starting the starter by preventing re-rotation of the lock cylinder core from the drive position to the start position, if this has already been reached before. Rather, it is necessary that after the one-time achievement of the starting position of the cylinder core must be turned back to the off position, so as to overcome the occasion repetition lock and to turn the cylinder core again from the off position to the start position.
- the return lock the cylinder core, in particular a form-fitting, with a simple rotation of the cylinder core blocked from the start position to the off position.
- the positive locking of the return lock blocks the cylinder core only from the drive position to the off position or even in the ACC position, as already described above. Only by destroying the positive locking of the return lock thus the cylinder core can be transferred from the start position or ride position in the ACC position or off position. This maximum security for the lock cylinder according to the invention can be achieved.
- the return lock has an adjustable locking element which mechanically blocks the rotation of the cylinder core from the drive position to the off position in a locked position and in a release position, the rotation of the cylinder core in the off position releases.
- the reset lock with the adjustable locking element in the locked position block the rotation of the cylinder core from the drive position to the ACC position. Due to the premature blocking of the cylinder core in the drive position to the ACC position, the safety of the lock cylinder is significantly improved - as already described. According to the invention, it is possible for the return lock to be arranged between the cylinder housing and the cylinder core.
- the already described positive connection of the return lock between the cylinder core and the cylinder housing, as in the locking members, which cooperate with the key, can be provided. It is conceivable that the return stop between an inner circumferential surface of the cylinder housing and an outer circumferential surface of the cylinder core is arranged. Due to the lateral arrangement of the return lock, the overall length of the lock cylinder according to the invention can be shortened. However, it is also conceivable that the return lock between a front or rear end face of the cylinder core and the complementary inner surface of the cylinder housing is arranged. In this variant, the length of the lock cylinder lengthens, but the width of the lock cylinder can be reduced.
- the return lock is arranged directly in the region of an insertion opening for the key channel.
- the return lock can also be provided on the front side of the insertion opening of the key channel at the opposite end of the cylinder core.
- This arrangement is particularly advantageous when a longitudinal displacement of the cylinder core is provided for actuation of the return lock.
- the actuation of the blocked return lock meaning the transfer of the return lock from the lock position to the release position, may be accomplished by longitudinal displacement of the cylinder core in the cylinder housing, as previously mentioned, or by actuation of an actuator mechanically cooperating with the lock element.
- the cylinder core In the longitudinal displacement of the cylinder core to overcome the reset lock is virtually the cylinder core itself or the key as an actuator. This results in a compressive or tensile force on the key, which is in the key channel from the cylinder core, to a longitudinal displacement of the cylinder core in the cylinder housing and thus to a transfer of the locking element of the return lock from the lock position in the release position.
- the reset lock is equipped with an additional actuator, this mechanically interacts with the locking element to cancel the positive engagement in the locked position and to transfer the return lock or the blocking element in the release position.
- the corresponding actuating element can be designed as a button, ring, in particular annular cap, or as a key (to move longitudinally to the cylinder core).
- the return lock is arranged in the axial extension of the cylinder core.
- the lock cylinder according to the invention can be made particularly narrow (see, for example, Fig. 9a) to g) and 10a) + 10b)).
- the return lock can be placed in a safe area at a steering lock, which is located just far away from an external access in a break-in attempt.
- the return lock between the cylinder core and a control for a locking pin for the functionally essential component can be arranged from the steering lock.
- the return lock may have a movable coupling element which is rotatably connected to the cylinder core.
- rotationally fixed is meant that a rotation from the cylinder core is transferred to the movable coupling element of the return lock can be configured on the cylinder core a corresponding coupling element in the form of a driver.
- This coupling element can be configured from a multi-tooth, a polygon or the like, which cooperates positively with a geometrically complementary designed counterpart in the return lock.
- the rotational movement of the cylinder core can be transferred to the movable coupling element, but preferably the cylinder core can be designed to be axially displaceable with the movable coupling element.
- the return lock to the blocking element also has a blocking path, which cooperate positively at least in the locking position, in particular the form-fitting is canceled when the locking element is in the release position and thus the locking element no longer engages in the locking path.
- the blocking element can be designed bolt-shaped and the blocking path can have an arcuate or L-shaped guide groove for the blocking element in the blocking position.
- the blocking element is arranged in or on the cylinder housing and the blocking path in or on the cylinder core.
- a complementary arrangement of the barrier track and the locking element is conceivable. The arrangement of the locking element on the cylinder housing facilitates the assembly of the lock cylinder according to the invention and a possible replacement of the locking element in the event of wear.
- the blocking element has a control slope, which interacts mechanically with a counter-control slope, whereby the blocking element is arranged longitudinally displaceable in or on the lock cylinder.
- a longitudinal displacement of the blocking element can be generated in order to transfer the blocking element from the release position into the blocking position and vice versa.
- It can be z. B. a pressure on the actuator of the return lock to produce a displacement of the counter-control slope, which cooperates with the control slope of the locking element and this shifts accordingly.
- the blocking element can be pressed from the locked position automatically in the release position.
- the control element itself can be arranged in a fixed part of the backstop, whereas the counter-control slope forms at least one movable part to the fixed part of the return lock.
- the blocking elements provided in the cylinder core are arranged in so-called locking member receptacles and in this case spring-loaded, in order to bring about a positive connection between the cylinder core and the cylinder housing in the blocking position.
- plate-shaped elements can be used as blocking elements, which are particularly stable and thus increase the breaking safety of the lock cylinder.
- they may have a passage opening for the key bit of the key, whereby the plate-shaped locking members in the cylinder core are pushed back and forth.
- the blocking elements are extended from the cylinder core shell side and interact positively with at least one recess in the lock cylinder housing.
- all locking elements are retracted into the cylinder core, so that the positive connection between the cylinder core and the cylinder housing is canceled and a rotation of the cylinder core in the cylinder housing by the introduction of the appropriate key is possible.
- At least one security element in the region of the key channel can be arranged in or on the cylinder core.
- this security element is preferably designed disc-ring-shaped and also has, like the locking members, a passage opening for the key bit of the key, which is designed more or less geometrically complementary to the outer contour of the key bit.
- the security element is constructed of hardened steel, so that a drilling of the keyway is impossible.
- the security element is designed to be rotationally symmetrical with respect to the lead-through opening, so that it can rotate in the cylinder core during a boring test.
- the security element can also be arranged in the form of a cap in front of or in the region of the insertion opening for the keyway.
- the blocking element of the return lock is arranged rigidly to the cylinder housing (see, for example, Fig. 9a) to g) and 10a) + 10b)).
- the blocking element itself performs no movement to the cylinder housing and is rather directly or indirectly fixed thereto, and in particular arranged on the outer radial circumference.
- the blocking element can be designed in the form of a cam, which is preferred has a drive element.
- This drive element may have the form of a run-on slope in order to be able to slide optimally along a blocking path of the return lock.
- this blocking element acts mechanically together with at least one longitudinally displaceable coupling element with the already mentioned blocking path of the return lock.
- the longitudinally displaceable coupling element is rotatably configured with the cylinder core, so that the coupling element rotates with a rotation of the cylinder core with.
- the longitudinally displaceable coupling element is spring-loaded by a spring in the direction of the cylinder core can be pressed.
- a control path for a position sensor can be provided on the coupling element. By this position sensor, the rotational position of the cylinder core or the associated rotation of the coupling element can then be detected metrologically.
- a longitudinal guide for a control of the steering lock is provided on the coupling element, wherein the control mechanically cooperates with the locking pin to block the functionally essential component, in particular in the form of a steering column.
- the control is rotatably but (axially) longitudinally displaceable to the movable coupling element (and thus also to the cylinder core) arranged.
- the control element can cooperate directly or indirectly with a starter switch via a driver and thus mechanically transmit the rotational movement from the cylinder core to the ignition starter switch.
- the control may indeed be rotatable itself, but not be arranged axially displaceable in the steering lock.
- the control element cooperates mechanically with the locking pin for the functionally essential component, the locking pin itself being spring-loaded and being pressed by the spring in the direction of the locking position, ie towards the functionally essential component.
- a displacement element in particular in the form of a lever element, can be provided between the cylinder housing and the cylinder core (see, for example, FIGS. 10a) + 10b)).
- This lever element expediently has a fixed pivot point, and is rotatably connected to the cylinder core via a rotation axis.

- the cylinder core 12 is in the start position III, which also represents a blocking position A of the return lock 15. From this position of the cylinder core 12 of the cylinder core 12 can be rotated only to the ride position II, since the existing positive fit 20 prevents further rotation counterclockwise of the cylinder core 12. So that now the positive connection 20 can be overcome by the locking position A of the return lock 15, the lock cylinder must be pressed by the key 14 into the cylinder housing 1 1, whereby the entire cylinder core 12 performs an axial movement in the direction of the control 72.
- the existing automatic key withdrawal lock 20 is simultaneously used as a return lock 15 for the cylinder core 12.
- the key withdrawal lock 26 has a drive 26.3, in particular in the form of a solenoid, which cooperates with a locking lever 26.1, and 26.2 has a fixed pivot point. With the open end of the locking lever 26.1, a blockage and thus a rotation of the control element 72 can be effected, since this has a radially outwardly projecting blocking path 17 with corresponding paragraphs 17.1, which can interact mechanically with the locking lever 26.1.
- the automatic key withdrawal lock 27 can be manually operated simultaneously via the manual actuator 19, in the form of a longitudinally mounted rod on the cylinder housing 1 1.
- the actuating element 19 must be pulled out of the cylinder housing 1 1, which simultaneously causes a rotational movement of the locking lever 26.1 about its pivot point 26.2, whereby a positive connection 20 between the locking lever 26.1 and the barrier web 17 can be achieved on the control 72.
- the pulling movement on the actuating element 19 can take place by means of a cam 12.10 on the cylinder core 12, which protrudes radially outwards, in the blocking position A of the return lock 15 (see FIG. 13c).
- the cylinder core 12 is axially displaceable and rotatably mounted in the cylinder housing 1 1 and is rotatably connected to the control element 12 by means of the coupling element 51.
