  • the overload lock provided there is intended to protect the lock cylinder from damage when execute unauthorized persons by means of a burglary tool violent rotations on the cylinder core.
  • the overload lock responds to a specific limit torque. In the normal case, with a rotation of the cylinder core by means of the proper key, the torque is transmitted to an output member of the lock cylinder, which performs the desired functions in the vehicle. But if the limit torque is exceeded by violent rotation without a key, the overload lock gets into an overload case, where by internal decoupling the torque does not reach the output member of the lock cylinder. Then no function is performed in the vehicle.
  • the cylinder core is idle together with the bearing sleeve rotatable with it.
  • the overload lock consists of a release sleeve with an axially fixed but rotatably connected sliding claw.
  • the sliding claw has a coupling part which engages in a counter-coupling part of the lock cylinder by spring force.
  • a coil spring surrounds a core of the output member and the sliding claw and provides for an all-round pressure between an inner flange of the release sleeve on a Outer flange of the sliding claw.
  • the invention has for its object to develop a functionally reliable lock cylinder referred to in the preamble of claim 1 species whose overload protection is improved. This is achieved by the measures specified in claim 1, which have the following special significance.
  • the invention uses a release lever which is pivotally mounted at its one circumferential location in the cylinder housing. In the transition between the normal and overload case of the release lever is transferred in an axial plane between two pivoting positions.
  • the release lever is combined with the driver to a common pivoting pivot unit.
  • the locking cam or the detent recess is seated at a circumferential location, which is opposite to the pivot bearing point of the release lever.
  • the pivot bearing is held stationary during the reversal between the normal case and the overload case, which is why more space remains at the opposite circumferential location.
  • the axial height of the latching cam and the latching recess can be made larger than in the known, parallel displaceable release member. Because of the larger training tolerances in manufacturing play a smaller size. Therefore, the limit torque in the invention is almost constant.
  • Fig. 2 is an analogous to Fig. 1 longitudinal section of the lock cylinder in
  • FIGS. 1 and 2 shows a perspective exploded view of the components of the lock cylinder shown in FIGS. 1 and 2, with a view of the outer front end of the cylinder core, wherein only one half of a cylinder housing is shown.
  • Fig. 4 is an analogous to Fig. 3 perspective exploded view of
  • Fig. 5 is a perspective view of the components shown in Figure 1 of the lock cylinder, the cylinder housing is longitudinally divided into two housing shells, one of which has been omitted, and
  • Fig. 6 is a perspective view similar to Fig. 5, where both
  • Housing shells of the cylinder housing are interconnected.
  • the lock cylinder initially comprises a cylinder core 10, which has a key channel 12 for insertion of a key not shown in detail.
  • the cylinder core 10 comprises not shown in detail chambers for tumblers, which are normally in locking engagement with a bearing sleeve 20.
  • the cylinder core 10 is rotatably mounted in the bearing sleeve 20. By the inserted key, the tumblers are reset, so that the cylinder core 10 can be rotated in the bearing sleeve 20 by means of the key.
  • the bearing sleeve 20 is rotatably mounted axially fixed in a cylinder housing 30, which consists of two housing shells 31, 32.
  • an overload lock 25 non-rotatable, as long as a torque is applied to the cylinder core, which is below a certain limit torque.
  • the components of such an overload lock 25 are best seen in Fig. 4 and include the following components.
  • the overload lock 25 initially comprises a disengaging member, which is designed as a release lever 40 in the invention.
  • the release member is in fact pivoted at a peripheral location at 42 in the cylinder housing 30, as shown in FIGS. 1 and 2 show. Opposite this pivot bearing point 42, the release member has a locking cam 41, which strives due to an axial, in the direction of the dash-dotted longitudinal axis 13 facing spring load 16 to engage in a detent recess 21 at the inner end face 22 of the bearing sleeve 20.
  • the release lever 40 is always positioned in a manner to be described laterally non-rotatably in the bearing housing 30, which is why the bearing sleeve 20 is held by the engagement of the latching cam 41 in the latching recess 21 is normally not rotatable.
  • Fig. 4 For the transmission of the rotation of the cylinder core 10 has a best seen in Fig. 4 recognizable offset cylinder inner end 14, which is coupled to a driver 50 in the normal case.
  • This coupling consists of a coupling part 51, which is normally in engagement with a counter-coupling part 11 of the cylinder core 10.
  • the coupling part is formed by a radial projection 51, which, as best seen in Fig. 3 can be seen, inside the ring 52 of the here formed as a circular ring driver 50 has.
  • the Counter coupling part consists of a best seen in Fig. 4 recognizable axial groove 1 1 in the remote cylinder inner end 14.
  • the driver 50 is located on the release lever 40, which in turn is formed as a circular ring.
  • the annulus of the driver 50 initially has an outwardly facing radial flange 53 which rests in the case of assembly on the annulus of the release lever 40, as shown in FIGS. 1 and 2.
  • radial flange 53 of the driver 50 but there is also an axial collar 54 which engages in the case of installation in the recognizable from Fig. 3 ring opening 43 of the circular release lever.
  • the normally caused by the key rotation rotation of the driver 50 is transmitted to the output member 35 via two mutually engaging connection means 57, 37.
  • the driver 50 has three webs 57 extending parallel to the longitudinal axis 13 and projecting from the annular body of the driver 50 on the inner end surface.
  • the second connecting means consist of axially parallel holes 37 in the output member 35, as shown in FIG. 3. In the present case, the webs 57 not only in the normal case, but also in the overload case with the holes 37 of the output member 35 in engagement.
  • the output member 35 endeavors, by means of a so-called pulse spring 26, which can be seen from FIGS. 1 and 2, to reach a defined zero position with respect to the cylinder housing 30.
  • the pulse spring 26 has two legs 27, 28, on the one hand hold an axial finger 38 from the output member 35 and on the other hand, a best recognizable from Fig. 6 web 33 between them. After a key turn, which is possible only in the normal case, therefore, the output member is moved back to its initial rotational position and thereby takes the cylinder core 10 in a corresponding zero position with.
  • the hook piece 44 engages around the circular ring of the driver 50 in the circumferential region radially and engages behind it in the case of assembly, as shown in FIG. 1, on its inner end face 56.
  • a jointly pivotable unit 55 In this pivot unit 55th but is, as already raised, the driver 50 with respect to the release lever 40 rotatable.
  • the release lever 40, and thus the entire pivot unit 55 held in a first pivotal position apparent from Fig. 1, which is marked by an auxiliary line 40.1.
  • This first pivot position can therefore be referred to as a "coupling pivot position."
  • pivot axis 45 is arranged by the release lever 40 vertically and at a radial distance from the longitudinal axis 13 of the lock cylinder.
  • a bearing piece 46 which is inserted in a radial recess 34 from the cylinder housing 30.
  • the mounting position of the bearing piece 46 is, as shown in FIGS. 1 and 2, secured by the peripheral surface of the bearing sleeve 20 in the recess 34. This facilitates the assembly of the lock cylinder according to the invention.
  • the pivot bearing 42 opposite, so on the shown in Fig. 4 free end 47 of the Ausgurhebels 40, except the aforementioned locking cam 41 is a guide piece 48.
  • This guide piece 48 engages in the apparent from Fig. 1 and 2 mounting case in an inner recess 39 of Cylinder housing 30 a.
  • the guide piece 48 and the housing Ausappel 39 provide during pivoting of the release lever 40 for a pivoting guide. Both by the guide piece 48 and by the pivot axis 45 on the bearing piece 46, the aforementioned rotationally fixed, but pivotally movable guide of the release lever 40 in the cylinder housing 30 is achieved.
  • the above-described axial spring load 16 engages only on the free arm end 47 of the release lever 40.
  • Serves a compression spring which is arranged in accordance with FIG. 1 in the aforementioned inner Ausappel 39 in the housing 30.
  • the compression spring is supported at one end on the inner axial end of the recess 39 and on the other hand on a removable best from Fig. 4 support point 17 at the free end of the arm 47 Ausgurhebels 40.
  • This support point 17 is integrated into the aforementioned guide piece 48.
  • the receptacle 18 can partially but also continue in the hook piece 44.
  • the guide piece 48 is a nose, which is arranged in the peripheral region of the annular body of the release lever 40 and protrudes at a right angle to a plane determined by the annular body of the release lever 40 lever plane. At the nose generated by the guide piece 48 and the locking cam 41 is formed, which belongs to the overload lock. Also, the hook piece 44 is arranged in the region of the nose, but runs counter to the locking cam 41.
