Definitions
- the invention relates to a Kraftfahrzeuiver gleich, with a locking mechanism consisting essentially of catch and pawl, and with a Gesperredämpfer.
- the state of the art has basically proven itself when it is a matter on the one hand to limit opening movements of the locking mechanism and, on the other hand, those which are associated with a closing movement of the locking mechanism.
- the previous solutions can not satisfy all around. For it disturbing lock noises are still observed, which are mainly due to the locking mechanism during its opening and / or closing movement.
- the invention aims to provide a total remedy.
- the invention is based on the technical problem of further developing a motor vehicle door lock of the embodiment described at the outset such that lock noises are reliably suppressed, in particular during the opening and closing operation.
- a generic motor vehicle door lock that limits the (a single) Gesperredämpfer in conjunction with associated Gesperreanellen both an opening and a closing movement of the locking mechanism.
- the locking mechanism ensures that lock sounds are absorbed by energy absorption at least during the opening and closing movement of the locking mechanism.
- the Gesperredämpfer is usually made of an elastomeric plastic, so it can reliably dampen existing noise with the opening and closing movement of the locking mechanism.
- the Gesperredämpfer is designed as rotatably mounted in the lock case and / or lock housing Wälzdämpfer.
- the Gesperredämpfer may have a connected to the aforementioned lock case and / or the lock housing axis of rotation, which may be made of steel, for example. This axis of rotation is formed either directly on the lock case respectively the lock housing or riveted, for example, to the aforementioned elements, screwed or otherwise connected as with these.
- the Gesperreanelle are each provided on the catch and executed on the one hand as opening stop and on the other hand as overstroke.
- the retainer is advantageously an annular disc made of an elastomer. This annular disc is equipped with a central bore, in which engages the mounted on the lock case and / or lock housing axis of rotation.
- the elastomers used are predominantly plastics such as acrylate rubber (ACM), acrylonitrile-butadiene rubber (NBR), chloroprene rubber (CR), ethylene-acrylate rubber (EAM), ethylene-propylene rubber (EPDM), natural rubber (NR ) or styrene-butadiene Rubber (SBR) is used, the list is of course not complete or must be.
- the Gesperredämpfer may additionally immerse in whole or in part in a movement path of the locking mechanism between the two Gesperreanoeuvre.
- This movement path of the locking mechanism is usually swept over by an outer contour of the rotary latch on which the locking mechanism rolls.
- the aforementioned Geperredämpfer is applied practically only rotary and performs no or only a little flexing.
- the Gesperredämpfer In the field of Gesperreanelle the Gesperredämpfer but is elastically deformed and compressed. The opposing forces thus built up for the locking disproportionately increase with increasing travel.
- the invention achieves this in essence by the fact that the Gesperreanelle are each arcuately formed with adapted to the diameter of the Gesperredämpfers radius and advantageously each have a rising edge in comparison to the movement path. Because this edge ensures that the Gesperredämpfer in the respective end position (opening or closing position or overstroke position) is increasingly deformed.
- a motor vehicle closure whose (single) locking mechanism limits both the opening movement and the closing movement or overheating movement of the locking mechanism, in conjunction with corresponding locking stops.
- both end positions it comes through the elastic deformation of the Gesperredämpfers to the desired energy absorption and noise reduction.
- disturbing Haupastastge syndrome be suppressed, resulting in the Set closed position or in the overstroke and frequently observed here in the prior art.
- the locking mechanism advantageously ensures that the entire movement of the locking mechanism during opening and closing of the lock as well as between these two positions is damped, because the locking mechanism is additionally immersed wholly or partly in the movement path of the lock between the two locking stops.
- FIG 1 shows the motor vehicle door lock according to the invention in its open position
- FIG. 2 shows the object according to FIG. 1 in the main locking position
- Fig. 3 shows the object according to Fig. 1 and Fig. 2 in its arrangement in the
- a motor vehicle door lock 13 is shown, which is equipped with a conventional locking mechanism of the catch 1 and pawl 2.
- the catch 1 interacts with a locking pin, not shown, which transfers the catch 1 from its open position shown in FIG. 1 in the closed position shown in FIG. 2 by engaging in an associated inlet mouth 3 and the catch 1 about its axis 4 in the transition from Fig. 1 to Fig. 2 pivoted counterclockwise.
- the rotary latch 1 with its axis of rotation 4 and also the pawl 2 with its (rotary) axis 5 are each mounted in a cross-sectionally U-shaped lock case 6.
- the not necessarily U-shaped lock case 6 also serves as a base or storage for a rotation axis 7, which receives a Gesperredämpfer 8 rotatably.
- the axis of rotation 7 is formed on said lock case 6, riveted to this, bolted thereto or the like.
- the axis of rotation 7 passes through a central bore 9 of the Gesperredämpfers 8, which is formed in the context of the embodiment and not limiting as a circular ring disk made of an elastomeric plastic.
- the locking damper 8 cooperates in two end positions of the locking mechanism 1, 2 with corresponding contours of the rotary latch 1.
- this Gesperreanedit 10, 11 are realized on the rotary latch 1.
- one or both Gesperrean redesign 10, 11 could also be provided on the pawl 2. This is not shown.
- the respective Gesperreaneau 10, 11 in conjunction with the Gesperredämpfer 8 ensure that both an opening movement and a closing movement of the locking mechanism 1, 2 are limited.
- the Gesperredämpfer 8 is designed as rotatably mounted in the lock case 6 Wälzdämpfer.
- the Gesperredämpfer 8 could additionally or alternatively be stored in a lock housing, not shown.
- the rotary latch 1 is acted upon by a spring, not shown, in a clockwise direction, said opening movement limited by the interaction of the Gesperreanschlag 10 with the Gesperredämpfer 8 becomes.
- the Gesperreanschlag 10 is thus an opening stop 10.
- the Gesperrean 8 in conjunction with the further Gesperreanschlag 11 ensures that closing movements of Locks 1, 2 are also limited.
- the Gesperreanschlag 11 acts in this context as Matterhubanschlag 11th
- the overstroke corresponds to the fact that the rotary latch 1 is pivoted counterclockwise about its (rotary) axis 4 beyond its main latching position shown in FIG. 2.
- the overstroke stop 11 and the friction damper 8 cooperate as the overstroke stopper 8, 11.
- Both the opening stop device 8, 10 and the overstroke stop device 8, 11 are characterized in that the respective stopper stops 10, 11 are each formed in an arc shape with a radius adapted to a diameter of the friction damper 8.
- the Gesperreanexcellent 10, 11 each have a rising in comparison to a trajectory 12 flank 10 ', 11', which increasingly deforms the Gesperredämpfer 8 in the respective end position (open position or closed position). That is, the respective rising flank 10 ', 11', the associated Gesperreanschlag 10, 11 ensures that disproportionately increasing counterforce forces are built up by the accumulator 8 in its deformation by the associated stop 10, 11.
- the Gesperredämpfer 8 additionally rolls along the path of movement 12 between the two end positions.
- the Gesperredämpfer 8 is mainly applied rotationally by rotating about its axis of rotation 7.
- the Gesperredämpfer 8 takes hardly deformation or flexing work on.
- the Gesperredämpfer 8 in the field of Gesperreanelle 10, 11 virtually no (more) acted upon by rotation, but is mainly deformed at this point elastically, and disproportionately with increasing adjustment.
- progressively increasing opposing forces in the open position as in the closed position or in the overstroke range are built up by the friction damper 8.
- an effective limitation of the adjustment path of the locking mechanism 1, 2 takes place, and in particular noise-damped.
