Abstract

The locking bolt of a steering lock for motor vehicles is additionally bolted in its locked position when the lock casing is tampered with. To achieve this, a set of transmission rods is divided up into two carriers, which are moved in opposite directions by means of a power transmission outlet, as a result of which the second carrier is moved forwards and brought into engagement with a lock when the first carrier is pulled out of its casing.

Description

Die Erfindung betrifft ein Lenkungsschloß für Kraftwagen nach dem Oberbegriff des Anspruchs 1.The invention relates to a steering lock for motor vehicles according to the preamble of claim 1.

Aus der DE-PS 31 31 558 ist bekannt, ein Sperrstück durch den Endbereich eines zum Sperrbolzen parallel verlaufenden Drahtes zu sichern und beim Abbrechen des Schlosses vom Hals der Sperrbolzenaufnahme durch Mitziehen des Drahtes zu entriegeln.From DE-PS 31 31 558 it is known to block by the end area of a parallel to the locking pin Secure wire and when canceling the lock from Neck of the locking pin holder by pulling the wire with it to unlock.

Dabei ist es ungünstig, den Draht parallel zum Sperrbolzen zu legen, da entweder zusätzliche Mittel notwendig werden, um den Draht und den Sperrbolzen in Abstand voneinander zu halten, oder ansonsten die Möglichkeit besteht, daß der beim Öffnungsvorgang bewegte Sperrbolzen den Draht mit sich zieht und damit das Sperrstück ungewollt freigibt.It is inconvenient to have the wire parallel to the locking pin as either additional funds will be necessary around the wire and the locking pin spaced apart hold, or otherwise there is a possibility that the Locking bolts move the wire during the opening process pulls and thus unintentionally releases the locking piece.

Es stellt sich die Aufgabe, das Sperrstück durch den Ver­ such, den Sperrbolzen unzulässig aus seiner sperrenden Position zu ziehen, in eine den Sperrbolzen verriegelnde Position zu bringen. It is the task of the locking piece by the Ver such, the locking pin is prohibited from its locking Position to lock the locking pin Position.  

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The task is characterized by the characteristics of the Claim 1 solved.

Die Einrastung des Sperrstücks in Abhängigkeit von der Ausziehbewegung des schloßseitigen Mitnehmerendes über eine zulässige Endposition hinaus gewährleistet eine be­ triebssichere Handhabung des Lenkschlosses und eine so­ fortige Verriegelung des Sperrbolzens beim Abbrechen des SchloßgehäusesThe locking of the locking piece depending on the Extending movement of the lock-side driver end over a permissible end position guarantees a be drive-safe handling of the steering lock and such continued locking of the locking pin when canceling the Lock housing

Die Gegenstände der Unteransprüche bilden vorteilhafte Ausgestaltungen des Gegenstandes des Hauptanspruches.The subjects of the subclaims form advantageous ones Refinements of the subject matter of the main claim.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, die ein Lenkungsschloß in einem Schnittbild zeigt.An embodiment of the invention is in the drawing shown that a steering lock in a sectional view shows.

Ein Lenkungsschloß umfaßt ein Schloßgehäuse 1 und eine daran angrenzende Sperrbolzenaufnahme 2. Das Schloßge­ häuse 1 ist in seinem dem Bediener zugänglichen Bereich mit einer umlaufenden Sollbruchkerbe 3 versehen, in der es beim Versuch, die Sperrbolzenaufnahme 2 zu öffnen, definiert abbricht.A steering lock comprises a lock housing 1 and an adjacent locking pin receptacle 2 . The Schloßge housing 1 is provided in its area accessible to the operator with a circumferential breaking notch 3 , in which it breaks off in a defined manner when trying to open the locking pin receptacle 2 .

Innerhalb des Schloßgehäuses 1 und der Sperrbolzenauf­ nahme 2 erstreckt sich ein Übertragungsgestänge, das ge­ steuert durch einen Schließexzenter 5, der zu einem nicht weiter dargestellten Schließzylinder gehört, nach Abziehen des Fahrzeugschlüssels die weitere Drehung einer Lenk­ spindel 6 verhindert und so den Kraftwagen unlenkbar macht. Within the lock housing 1 and the Sperrbolzenauf measure 2 extends a transmission linkage that controls ge by a locking eccentric 5 , which belongs to a lock cylinder, not shown, after removing the vehicle key prevents further rotation of a steering spindle 6 and thus makes the motor vehicle unmanageable.

Hierzu rastet ein in der Sperrbolzenaufnahme 2 geführter Sperrbolzen 7 in eine Aufnahmebohrung 8 der Lenkspindel 6 ein.For this purpose, a locking pin 7 guided in the locking pin receptacle 2 snaps into a mounting hole 8 of the steering spindle 6 .

Der Schließexzenter 5 drückt auf eine Anlagefläche 9 eines Führungskörpers, der sich zu einer Stange 10 verengt, die eine enge Gehäusewandbohrung 11 durchgreift und verzahnt als ein erster Mitnehmer 12 endet.The closing eccentric 5 presses on a contact surface 9 of a guide body, which narrows to form a rod 10 which passes through a narrow housing wall bore 11 and is toothed and ends as a first driver 12 .

Dieser wirkt über ein Zahnrad 13 auf einen zweiten Mit­ nehmer 14, der den Sperrbolzen 7 verschiebt.This acts via a gear 13 on a second participant 14 , which moves the locking pin 7 .

Wird nun das Schloßgehäuse 1 abgebrochen, um den Sperr­ bolzen 7 aus seiner sperrenden Position zu ziehen, so drückt eine vorgespannte Feder 15 den ersten Mitnehmer 12 über seine zulässige Endposition hinaus von der Lenk­ spindel 6 weg, wodurch der zweite Mitnehmer 14 ein zu­ sätzliches Stück hin zur Lenkspindel 6 bewegt wird, und dadurch eine federbeaufschlagte Sperre 16 einrastet, die die sperrende Position des Sperrbolzens 7 verriegelt. Diese Verriegelung ist für weitere Manipulationen nicht mehr zugänglich.If the lock housing 1 is now broken off in order to pull the locking bolt 7 out of its locking position, a prestressed spring 15 presses the first driver 12 beyond its permissible end position from the steering spindle 6 , whereby the second driver 14 removes an additional piece is moved towards the steering spindle 6 , and thereby a spring-loaded lock 16 engages, which locks the locking position of the locking bolt 7 . This lock is no longer accessible for further manipulation.

Um den zusätzlichen Weg des zweiten Mitnehmers 14 zu ermög­ lichen, ist dieser über ein Langloch 17 und einen dieses durchgreifenden Bolzen 18, der im Sperrbolzen 7 gelagert ist, gegen die Kraft einer Feder 19 gegen den Sperrbolzen 7 verschiebbar.In order to make the additional path of the second driver 14 possible, it is displaceable via an elongated hole 17 and a bolt 18 penetrating this, which is mounted in the locking pin 7 , against the force of a spring 19 against the locking pin 7 .
