Definitions
- the invention relates to a locking device for motor vehicles one rotatably mounted in a housing of a locking cylinder Cylinder core, in the axial key channel of which a key can be inserted if the key is correct, locks the cylinder core into a position in which the cylinder core is rotatable relative to the lock cylinder and one Takes control shaft, which is a component to be closed or opened Motor vehicle, in particular can operate a lock, the Control shaft can be uncoupled from the cylinder core, if by a wrong one Key or is twisted by force of the cylinder core.
- Such a locking device is for example from DE 40 41 134 and EP 0 611 860. It includes a housing with an in the housing rotatably arranged, having a key channel Cylinder core which, when a key is withdrawn from the key channel Tumblers with one arranged between the housing and the cylinder core Cylinder liner can be locked. There is also an overload clutch device provided so that with a rotary actuation of the cylinder core with a not intended key or tool with the lock connected output element is uncoupled from the cylinder core.
- the overload clutch device consists of at least one radial movable and rotatably connected to the cylinder core driver, the is supported radially outward on the drive element and in a driving groove engages the drive element, and one with the driver in the event of an overload cooperating control.
- the latter is one Tappet in a radial recess of the Is stored and by rotating the cylinder liner from the Radial recess is pressed and the driver moves radially.
- a disadvantage of the known lock cylinder is i.a. the relative elaborate control of the driver in the event of an overload and the necessary Space.
- DE 692 00 617 T2 discloses a locking cylinder with one in one Housing arranged cylinder core and a cylinder liner known.
- the cylinder liner when the cylinder core rotates rotates, the cylinder liner has radially extending legs, which in Overload case pressed into corresponding recesses in the cylinder core be and cause entrainment of the cylinder liner.
- DE 694 00 327 discloses a further development of DE 692 00 617, wherein the radial legs of the cylinder liner by at least one separate lever to be replaced with its first end in one appropriate recess of the cylinder liner can be used and, depending on State of the lock cylinder, with its second end in one Recess of the cylinder core or in a recess of the housing intervenes.
- Another locking device is known from DE 40 16 779, which is used as a steering lock.
- the between the lock cylinder and the Control shaft arranged parts increase the axial length of the steering lock. Furthermore, the key must be pressed when the lock is operated relatively high torque are used.
- the object of the invention is a steering lock of the aforementioned Type to improve so that with a small overall length smooth operation of the lock with the key.
- the locking device according to the invention is particularly simple Construction, high functionality and has only a few parts.
- the bolts are outside the key guide, so that they are not accessible from the outside, which affects the effectiveness of the inventive Theft protection increased.
- he invention provides that between the disc and the control part a rotatable switching ring is provided, which with cooperates with the control part and with its side facing away from the control part forms a receptacle for the disc and this against the cylinder core centered.
- the axial control part is advantageously designed as a cylinder liner, which has at least one at its end facing the control shaft Has an inclined surface with the corresponding surface of the switching ring in the Way cooperates that with a wrong key or a Breaking tool an axial displacement of the switching ring and thus the Disc is effected.
- 1 is a lock cylinder of the invention Called locking device.
- This lock cylinder is for example for one Locking system for a car door or for a steering lock.
- the Lock cylinder 1 contains one, rotatably arranged in a housing 2 Key channel 3 having cylinder core 4.
- the cylinder core 4 is in the locked state of the lock cylinder 1 shown schematically Tumblers 5 with one between the housing 2 and the cylinder core 4 arranged cylinder sleeve 6 (this can be designed as a locking bush) non-positively connected.
- control shaft 7 can also be further developed as an actuating lever in order to open or component to be closed, in particular to operate a lock.
- the control shaft 7 is by the components described by the Cylinder core 4 can be uncoupled if by a wrong key or by Use of force of the cylinder core 4 is rotated.
- an axial control part coupled to the cylinder core 4 8 provided by the cylinder core 4 in the locked state of Lock cylinder is rotatable.
- the control part 8 is more advantageous than Cylinder sleeve 6 formed, which facing the control shaft 7 End 9 has at least one inclined surface 10.
- the locking device according to the invention has one on the Cylinder core 4 mounted disc 11, which by the axial control part 8 from Cylinder core 4 can be pushed axially away.
- the control shaft 7 has on the cylinder core 4 facing End at least one, advantageously several regularly over the Circumferentially distributed, spring-mounted axial bolts 12. As shown in FIG. 2, the locking device described here has two diametrical opposite bolts 12.
- each bolt presses with its head end 14 against the disc 11.
- a non-rotatable Switching ring 15 is provided, with its surface facing the control part 8 cooperates with the control slope 10 and with the control part 8 opposite side 16 forms a receptacle 17 for the disk 11 and this centered relative to the cylinder core 4.
- control shaft 7 has four evenly the circumference distributed recesses 19 in the corresponding cam 18 of the Engage switching rings 15 and thus secure them against rotation.
- a locking washer 20 is shown in Figure 1, which secures the lock cylinder 1 against axial displacement.
- the locking device according to the invention works in the following Wise :
- the tumblers 5 are not from the cylinder core 4 the corresponding recesses of the cylinder liner 6 drawn. It stays there is a positive connection from the cylinder core 4 to the socket 6.
- the socket 6 rotates in the housing 2 and controls the switching ring 15 in the Way that this is pushed in the direction of the control shaft 7.
- the locking device according to the invention has a small Depth.
- the lock cylinder unit can be outside the housing be preassembled, inserted into the housing 2 from the rear, and held by the lock washer 20.
- Such an assembly sequence ensures a high level of security against theft guaranteed against knocking in or pulling out the locking cylinder.
- this arrangement makes it simple Mount the plastic cap without reducing the anti-theft device.

Abstract
Description
- daß die Schliessvorrichtung eine auf dem Zylinderkern gelagerte, Scheibe aufweist, die durch ein axiales am Schliesszylinder angekoppeltes Steuerteil vom Zylinderkern axial weg drückbar ist,
- daß die Steuerwelle an ihrem dem Zylinderkern zugewandten Ende mindestens einen federnd gelagerten axialen Riegel aufweist, welcher in eine entsprechende, an dem der Steuerwelle zugewandten Ende des Zylinderkerns vorgesehene Aufnahme des Zylinderkerns eingreift, um bei einem richtigen Schlüssel die Drehung des Zylinderkerns auf die Steuerwelle zu übertragen, und
- daß der Riegel so angeordnet ist, daß er bei einem falschen Schlüssel oder einem Aufbruchwerkzeug von der Scheibe entgegen der auf ihn wirkenden Federkraft aus seiner am Zylinderkern vorgesehenen Aufnahme gedrängt wird, so daß der Zylinderkern und die Steuerwelle entkoppelt sind.
