Definitions
- the present invention relates to a guide device for guiding a locking bolt of a steering lock and a steering lock with such a guide device according to the respective independent claims.
- steering wheel lock This is a mechanical lock of the steering shaft of a steering device of the vehicle.
- a steering device is usually equipped with a steering shaft, which transmits the steering rotation movement to corresponding adjusting mechanisms.
- grooves are formed, in which in radial direction can engage a corresponding locking pin of the steering lock. Once the locking pin engages in this locking groove of the steering shaft, a rotation of the steering shaft is no longer possible. For normal operation of the vehicle is therefore the locking pin disengaged from these locking grooves.
- a disadvantage of the known solutions is that a guide of the locking pin between the locking and the releasing position is necessary, which is exposed to mechanical stress.
- the corresponding holding forces must be removed or absorbed not only by the steering shaft and the locking groove, but also by the corresponding guide device of the steering lock on the locking pin.
- a side surface of the locking pin contacted with corresponding guide surfaces of the guide device over which these supporting forces are removed.
- This can lead to large mechanical effects can lead to structural damage of the material of this guide device.
- a guide device for guiding a locking bolt of a steering wheel lock.
- the guide device is equipped with a base body having at least four inner walls designed as guide surfaces, which surround a guide opening of the base body.
- a transition section is arranged with a guide free passage between at least two of the at least four guide surfaces.
- the guide clearance has a first curvature portion and a second curvature portion with different radii of curvature.
- three or more curved sections with different radii of curvature can of course also be provided according to the invention.
- a continuous change of the radius of curvature is conceivable, so that, for example, a parabolic curved contour is formed.
- each locking device for a functionally essential component on a vehicle usually the functionally essential component of the vehicle by the locking device in the locked position by the locking pin in particular form-fitting (possibly additionally also non-positively) locked.
- the locking pin of the locking device releases the functionally essential component for free use.
- the functionally essential component may be at least a steering column, a brake pedal or a gear lever, which is locked or blocked by the locking device in the locked position and thus is inoperative.
- the guide device according to the invention is used on the locking device or the steering lock. For simplicity, in the following text only ever spoken by the steering wheel lock, even if any other locking device is meant.
- the main body of the guide device may also be at least partially formed by a part of a housing of the steering lock.
- This hard / break-proof materials are used for the body and the housing in the rule, such as z. B. cast metal alloys, light metal (pressure) cast, aluminum zinc die casting or zinc die-casting alloys (eg Zamak) or combinations thereof. These materials are characterized by high mechanical stability and are corrosion resistant. Overall, it is thus possible to form a particularly stable and robust guiding device.
- a guide device is thus based on known technical solutions, which enable a guided movement of the locking pin between a blocking position and a release position by a leading contact between guide surfaces and corresponding side surfaces of the locking pin.
- the locking pin In the event that the locking pin is in the locked position, it may be that in an attempted steering movement of the locking pin locks against this attempted steering movement.
- the locking forces introduced for this purpose are now removed via the locking bolt and the contacting between the respective guide surface and the contacting side surface of the locking bolt in the guide device.
- a different radius of curvature preferably a significantly smaller radius of curvature, now return the side surface of the guide slot to the adjacent guide surface, in particular the secondary guide surface explained later, with the aid of the second curved section.
- such a guide device can be made of different materials.
- the main body can be made of cast materials, for example, in a casting process.
- Other manufacturing methods for example, an additive constructive manufacturing method with so-called 3-D printing method are quite conceivable in the context of the present invention.
- the locking pin is designed to be essentially free in terms of its movement.
- the locking pin may be movable along a straight line between the locking position and the release position.
- also obliquely arranged movement modalities for the locking pin are quite conceivable within the meaning of the present invention.
- the transition section between at least two guide surfaces is to be understood as the region which results from the introduction of the guide free passage between these two guide surfaces.
- the transition section is thus preferably provided with its own transitional surface, wherein the entire guide free passage and thus the entire transition section with its transition surface is contact-free to the respective locking pin in its leadership.
- a cross section through the locking pin is designed geometrically deviating from a cross section through the guide region, in particular by at least one transition section, geometrically.
- the two cross sections of the locking pin and the guide portion of the guide device are not geometrically complementary to each other just in the region of the transition sections.
- the guide region of the guide device is formed in particular by the guide surfaces.
- the corners of the locking pin are not at the corners of the guide device, in particular in the transition section to each other and are thus designed contactless.
- increased support forces can be avoided just in the transition sections, which can also reduce the wear on the guide device and the locking pin significantly.
- the inner walls which are formed as guide surfaces, can be geometrically adapted to the corresponding corresponding side surfaces of the locking bolt.
- both the guide surfaces and the side surfaces of the locking pin are flat or substantially planar.
- a substantially rectangular cross-section of the locking pin is preferred with a corresponding corresponding rectangular cross-section of the guide opening in the base body.
- two opposing guide surfaces as main guide surfaces and two further opposite guide surfaces as secondary guide surfaces are formed which are smaller than the main guide surfaces.
- at least between a main guide surface and a secondary guide surface of the transition section is arranged with the guide free passage.
- the distinction between the main guide surfaces and secondary guide surfaces is to be understood in particular on the overall geometric size of these guide surfaces.
- the respective guide surface corresponding to the respective side surface of the locking bolt then a large main guide surface, if it is preferably aligned with its surface normal in the circumferential direction of the steering shaft to be blocked.
- the blocking forces that occur are therefore usually removed via the correspondingly larger main guide surfaces, so that the secondary guide surfaces play a significantly smaller role for the removal of blocking forces.
- This also means that the advantages according to the invention can already be achieved if the guide free passage according to the invention is provided on at least one transition section between at least two of the four guide surfaces.
- the advantages can be further improved if at two, three or even at all transitional sections of all existing guide surfaces, the corresponding guide free periods are provided.
- the first curvature section has a greater radius of curvature than the second curvature section, wherein the first curvature section merges into the sub-guide surface and the second curved section merges into the main guide surface.
- the main guide surface serves to provide the main Abtrage réellekeit for the blocking force in the blocking use of the locking pin.
- the corresponding adjacent surface of the first curvature section is Accordingly, equipped with a smaller radius of curvature, so that a distribution of the blocking force to be removed takes place over a larger material area of the base body of the guide device.
- the second curvature section can now connect with a significantly greater radius of curvature, this second curvature section no longer the distribution of the locking forces as the main function, but rather the most compact return of the guide free passage to the side -Facing the goal. This reduces the entire sharp-edgedness of the guide clearance and at the same time achieves the advantages according to the invention with the most compact possible design.
- the guide free passage between the first curvature section and the second curvature section has at least one third curvature section whose radius of curvature is formed between the curvature radii of the two adjacent curvature sections.
- the first curvature section and the second curvature section are, so to speak, the sections of the guide free recess which form the two edge regions in transition to the two adjacent guide surfaces. It is even preferable if the radii of curvature are changed substantially continuously with regard to their differences between the first curvature section and the second curvature section.
- the guide opening has a rectangular or substantially rectangular shape, wherein the centers of curvature of the first curvature portion and the second Curvature portion, in particular of all curvature portions lie on the same side of a diagonal of the guide opening, which extends through the guide free passage therethrough.
- locking pins are often used as cuboidal bolts.
- the corresponding guide opening or the cross-sectional area for the passage of the locking bolt of the guide opening is therefore likewise rectangular. Connecting the corresponding opposite corner points of this rectangle with each other results in the diagonal of the guide opening defined in this embodiment. This diagonal can be defined beyond the guide opening through the respective guide free passage of the transition section.
- the centers of curvature of at least the first curvature section as well as the second curvature section are now on the same side of this diagonal.
- the guide free recess has a smaller extension into the depth of the main body than the guide opening.
- significantly more material can be made available for the base body in the depth of the guide opening in order to form a higher material thickness with greater stability corresponding to the positions of the base body lying in the depth.
- this guide free passage preferably extends in depth at least approximately 5 mm into the basic body in the depth direction.
- a guide surface preferably a secondary guide surface
- the two adjacent Guide surfaces each having a transition section with a guide free passage.
- the respective secondary guide surface is equipped with the functionality according to the invention of the guide free grooves.
- all transition sections between all existing guide surfaces are preferably equipped with the quality of the guide free rungs according to the invention.
- the guide surface between the two guide free grooves is designed as a guide web.
- the corresponding geometry of the radii of curvature for the existing curvature sections of the individual guide free strokes can be adjusted even more freely to the respectively existing force situation.
- each transition section can be equipped with a geometric basic pattern specific to these two adjacent guide surfaces for the individual radii of curvature.
- the individual guide free passages of the individual transition sections are identical to one another or else have different configurations of the radii of curvature.
- the two adjacent transition sections merge into one another and thus at least partially replace the intermediate guide surface.
- the guide surface is replaced by the two transition sections.
- the two free-practice periods are therefore merging.
- the guide surface for forming the lateral guide can be present again.
- a lateral support To ensure, according to the invention, a locking pin can be used, which itself has a lateral guide web. This web can be designed rib-like with substantially straight edges and side surfaces.
- a locking pin is also conceivable, whose side surface has a convex surface which, in particular linienformig, takes over the leading contact with the two merging transition sections.
- an edge is formed between the first curvature section and / or the second curvature section and the respectively adjacent guide surface with a transition radius with curvature opposite to the curvature of the respective curvature section.
- At least one of the guide surfaces preferably two opposite guide surfaces, in particular all guide surfaces, have a flat or substantially planar extension. It is a particularly simple and cost-effective way to provide or produce a guide device according to the invention. Of course, however, also cambered or curved guide surfaces are conceivable.
- a steering lock for locking the function of a steering wheel of a vehicle comprising a locking pin for locking engagement in a steering shaft of the vehicle.
- the locking pin is guided by means of a guide device according to the invention.
- An inventive steering lock can be further developed such that the locking pin has side surfaces which are at least partially in leading engagement with the guide surfaces of the guide device.
- at least one pin edge between the two adjacent side surfaces of the locking pin is disposed without contact in a guide free passage of the guide opening of the guide device.
- the locking pin manually, for example.
- a lock cylinder is driven or that the locking pin automatically, for example.
- a drive driven, whereby the locking pin is movable at least between a locking position and a release position .
- the locking pin is manually driven by a lock cylinder, it is at the steering lock to a (pure) mechanical steering lock.
- the rotation of a matching key in the lock cylinder is transmitted via transmission means on the locking pin and thus serves as a drive.
- a drive in particular in the form of an electric motor, is provided, the locking bolt can be driven automatically by the drive. In this respect, this is an electromechanical steering lock.
- the advantage of this variant is that the electrical controls and query whether the steering lock between the lock position and the release position can change structurally separated from the electromechanical steering lock can be arranged.
- a corresponding steering lock can be arranged at any point in the vehicle.
- the advantage is that even in the event of a power failure, the steering lock remains fully functional.
- the locking bolt has a lateral guide web, which merges into one another Transition portions of the guide device leading contacted.
- the guide web of the locking pin is formed rippenformig.

In both variants, the two transitional sections 40 merge into one another centrally at the two upper edges. In order to further create a lateral guide functionality, the two locking pins 1 10 are equipped with a guide web 1 12. In Fig. 9, this guide web 1 12 is designed rib-shaped. In order to provide an even better tolerance compensation, in the embodiment of FIG. 8, the guide web 1 12 of the locking pin 1 10 is formed as a convex surface. Thus, even with a tilting of the locking pin 1 10 nor the desired leadership functionality can be provided.
