Description

The present invention relates to a motor vehicle lock according to the preamble of claim 1 and a use of a motor for opening a Pawl of a motor vehicle lock according to the preamble of the claim 22nd

The term "motor vehicle lock" is primarily a door lock of a motor vehicle to understand. However, this may also be a trunk lock, a hood lock, a flap lock or the like of a motor vehicle act.

A known for example from DE 196 14 122 A1, especially for motor vehicle side doors widely used vehicle lock has a latch and a associated pawl on. The lock catch can be a closing bolt or so-called Hold the locking wedge or secure and in turn by the pawl locked, in a main position and pre-locking in the latch can come up. The pawl is designed hook-shaped here.

DE 20 01 653 A shows a motor vehicle lock with a latch and a associated pawl, wherein the pawl is not hook-shaped, but is configured substantially in the manner of a pivotable bolt. The bolt has a recess for forming an engaging portion, the by pivoting the bolt in locking engagement with the latch can be brought. The actuation of the pawl thus formed via a conventional Lever assembly.

DE 101 11 085 A1, which is the starting point of the subject of the claim 1 discloses a motor vehicle lock with a latch and a pawl, for example, actuated by an electric motor via a worm gear is. Such a transmission requires a high accuracy of all components and therefore high production costs. In practice, it has been shown that a Worm gear tends to premature failure. Another disadvantage is in that a worm gear engine noise on all other components transmits, so that the motor vehicle lock undesirably high operating noise shows.

DE 196 04 724 A1 discloses a vehicle lock with a latch and an associated pawl. A cable pull referred to, flexible tension element connects the pawl with a handle, so that by manual operation the handle, the pawl can be opened. A motor Drive the pawl is not provided.

DE 102 00 551 A1, which is the starting point of the subject of the claim 32 discloses a motor vehicle lock with a pivotable pawl, the immediate of a fuse or holder of a locking pin or closing wedge in an inlet slot of the motor vehicle lock in the locked or blocking state is used. The pawl can be manual or motorized be pivoted in the opening direction via an opening element. The opening element can have a cable. Concrete instructions for realization an opening drive means of a flexible traction means are called However, not a publication.

The present invention is based on the problem of a motor vehicle lock and the use of a motor for opening a pawl of a Specify motor vehicle lock, so that a simpler and cheaper Construction with few components and / or simple activation is made possible where a robust, low wear underlying construction with low Operating noise is feasible.

The above problem is solved by a motor vehicle lock according to claim 1 or a use according to claim 22 solved. Advantageous developments are Subject of the dependent claims.

A basic idea of the present invention is a flexible one Traction means, in particular a rope or band to provide, preferably directly from the engine or an output shaft of the engine is wound and acts directly or indirectly on the pawl. In particular, the Pawl be opened by means of the traction device against spring force. this makes possible a simple and inexpensive construction, since only a few components and no particularly precisely manufactured components are required. Another Advantage is that running noise of the engine from the traction means or at most be transferred to other parts only to a limited extent. Another Advantage is that a precise gear engagement, as in a worm gear, is not required, so that related wear problems avoided can be. Finally, with the drive technology use of above traction agent basically insensitive to contamination guaranteed. Also required for gear drives fats deleted Completely.

Another advantage of the solution according to the invention is that a low Self-locking is feasible. So it is preferably provided that after the Switching off the motor, the traction means automatically by spring force unwinding again and thus the pawl zurückbewegbar in its locked position is pivotable. Preferably, the restoring force is generated by a spring, which is present anyway and for example the pawl or a associated with the pawl cam follower o. The like. Is assigned. So be both a simple and therefore cost-effective design as well as a simple Control enabled.

Preferably, on the pawl or an associated drag lever a Deflection roller arranged for the traction means and the free end of the traction means for example, on the housing of the motor vehicle lock resisted. So will realized in a simple way a translation, by appropriate choice the geometric relationships and arrangements a needs-based gear ratio is feasible.

A particularly robust arrangement results from the fact that the traction means between the engine and the pawl formed a direct connection Connection without intermediate lever is. An adaptation of the Translation can be achieved by the possibility of variation reach the diameter of the output shaft.

To a particularly compact and cost-effective variant leads the equipment of the pawl with a substantially cylindrical section, on the lateral surface of the traction means is attached. The traction means will then in the adjustment of the pawl, as it were over a certain Angle range on or unwound. This angular range is preferably significantly less than 180 °.

Fig. 1 shows a schematic representation of a motor vehicle 1 with several Motor vehicle locks 2, in particular side door locks, a hood lock or similar. The arrows in Fig. 1 indicate the approximate mounting positions the illustrated motor vehicle locks 2 in the motor vehicle 1 at.

The construction of a proposed motor vehicle lock will be described below 2 explained in more detail.

Fig. 2 shows a schematic representation of a preferred embodiment of a Proposed motor vehicle lock 2 in the locked state. The Motor vehicle lock 2 has a latch 3 designed here as a rotary latch, an associated pawl 4 and a motor 5 for opening the pawl. 4 on.

The pawl 4, the latch 3 preferably in a main latching position and a pre-locking position, as is common in most motor vehicle door locks, secure - hereinafter called blocking position - and thereby the motor vehicle lock Lock 2.

From the blocking position in which the pawl 4 with the latch 3 in engagement can stand or kick, the pawl 4 can be moved to a disengaged position, in particular, be pivoted. This will be referred to as opening or open position of the pawl 4 denotes.

The motor 5 is preferably designed as an electric motor. However, it can be basically also act on any other suitable drive.

The motor vehicle lock 2 has a flexible traction means 6, so that the engine 5 actuate the pawl 4 by means of the traction means 6, in particular open, can.

According to one embodiment, the traction means 6 directly on the Pawl 4 attack. This is in connection with in Figs. 6 to 8 illustrated embodiments explained in more detail. In the illustrated in Fig. 2 Embodiment engages the traction means 6, however, only indirectly on the Pawl 4 on, via one of the pawl 4 associated rocker arm 7th

The traction means 6 is preferably designed as a rope, band or chain. Especially it has a round or flat cross-section.

The traction means 6 may optionally be formed in one piece or mehrgliedrig.

In particular, the traction means 6 of several, preferably stranded filaments or strands formed. In the illustrated embodiment, this is Traction means 6 formed like a rope.

The traction means 6 is preferably made of plastic and / or steel.

According to a preferred variant, the traction means 6 is a flat plastic or Steel band formed.

The traction means 6 is preferably gearless from the engine 5, in particular directly on an output shaft 8 of the motor 5, wound up. This is the traction means 6 with one end positively or positively connected to the output shaft 8. Preferably, the traction means 6, for example, in one with the output shaft 8 firmly connected receiving part 9 is injected or pressed or attached to it in any other way.

The receiving part 9 is preferably designed flange-like and forms a axial stop for winding the traction means 6 on the output shaft. 8

The output shaft 8 preferably provides a sufficiently long engine shaft of the motor 5. However, it may also be at the output shaft 8 act a prolonged or additional shaft portion, the actual Motor shaft flanged in motor 5 or in any other way with this is directly connected.

If necessary, the output shaft 8, however, also not shown Transmission are driven by the engine 5. In this case, the transmission is preferred integrated into the engine 5 or flanged directly to this. Preferably, it is then a geared motor.

The motor vehicle lock 2 is preferably designed such that the traction means 6 helically and / or only single-layer wound on the output shaft 8 is. This is achieved in particular by the traction means 6 in Dependence on a pivoting position of the pawl 4 or the rocker arm 7 offset or guided accordingly during the winding process becomes. Thus, a minimal wear of the traction means 6 and a precise, Repeatable behavior of the drive train formed allows (see FIG. 2/3).

Preferably, on the output shaft 8, a winding stopper 10 so to Receiving part 9 spaced arranged that between the receiving part 9 and the winding stop 10, the traction means 6 can be wound onto the output shaft 8 is. In particular, the winding stop 10 is formed flange. So will one ensures safe guidance of the traction means 6 on the output shaft 8.

Preferably, the traction means 6 forms a cable pull 11. For this purpose, the traction means is the sixth to a serving as a "loose role" pulley 12 on the pawl 4 or As shown in the illustration - guided on cam follower 7. With his other or free end is the traction means 6 on the motor vehicle lock 2 and its housing 13 resisted. Preferably, the traction means 6 on the housing 13, in particular attached to a suitably trained storage block or the like or pressed in order to allow easy mounting. however If necessary, the traction means 6 can also be provided with an end region, for example be injected or otherwise connected to the housing 13.

Depending on the geometric arrangement of the components to each other and depending on the direction of the drive shaft 8 to the guide roller 12 and of the guide roller 12th to the housing 13 running traction means 6 to each other and to the direction of movement - Here pivoting movement - the drag lever 7 (or the Pawl 4) results in a reduction ratio, the corresponding Choice almost arbitrarily adapted and in particular depending on the Swivel position, ie with the opening movement, can vary.

In particular, the cable 11 initially forms a starting position from the blocking position relatively large reduction of engine movement to a large opening force or Aushebekraft on the possibly of the latch 3 heavily loaded Pawl 4 and / or to overcome Abreibungskräfte exercise too can. In the further course of the opening then preferably reduces Reduction ratio, to a total of a relatively quick opening of the pawl 4 to allow.

The pawl 4 is preferably biased in the blocking position by spring force. The drag lever 7 is preferably also in the in Fig. 2 shown Position that allows a collapse or a blocking function of the pawl 4, biased, the drag lever 7 regardless of the pivoting position of the Pawl 4 is biased in this position by spring force.

Preferably, the pawl 4 and the finger lever 7 are separated by two separate, not shown springs or by a common, especially on the Pivot axis of the pawl 4 and / or the finger lever 7 arranged spring 14, as indicated in Fig. 2 and 3, biased in the directions mentioned. Against the force of this spring 14, the traction means 6 can be wound up by the motor 5.

Fig. 3 shows in a corresponding to Fig. 2 representation of the motor vehicle lock 2 in open condition with open pawl and open rocker arm 7 and wound with traction 6.

The force acting on the pawl 4 biasing force and / or on the rocker arm 7 acting biasing force is or are preferably selected and such to the transmission or reduction ratio of the cable 11 and other mechanical Influences, such as the stiffness of the motor 5, adapted that when switched off Motor 5, the traction means 6 due to said biasing force or prestressing forces can be unwound automatically from the output shaft 8, so that the drag lever 7 and / or the pawl 4 automatically back into the Locking position or the blocking position of the pawl 4 gestattende position is recoverable or are. So a very simple construction and a very simple control of the motor vehicle lock 2 allows.

2 shows the motor vehicle lock 2 in the locked or closed state, wherein the lock latch 3 a closing or locking key 15 or The like in an inlet slot 16 holds or secures, as indicated schematically. The latch 3 is in turn in this state by the sunken Pawl 4 locked against opening or secured.

According to a variant, not shown, the pawl 4, if necessary also be hook-shaped and immediately a fuse serve the closing or closing striker 15 or the like. Possibly the pawl 4 can have at least two hook sections, to the usual Hauptastaststellung and Vorraststellung a conventional door lock to recapture with latch.

Hereinafter, with reference to FIG. 4, another embodiment of the proposal Motor vehicle lock 2 explained. Here are only significant differences compared to the first embodiment explained. Otherwise result in corresponding or comparable properties and advantages, the above statements apply mutatis mutandis.

In the second embodiment, the traction means 6 is not around the deflection roller 12, but via a translation gear 17 to the pawl 4 or - as in the illustration - Guided to the drag lever 7.

The translation wheel 17 is preferably formed such that it is the Aufwikkelbewegung of the motor 5 for the pawl 4 and the drag lever 7 is reduced. The translation wheel 17 is quasi a transmission for the traction means 6.

In the illustrated example, the translation gear 17 has a first motor side Winding 18 and a second, output-side winding area 19 on. The winding areas 18, 19 are preferably at least substantially arranged coaxially and in particular firmly connected to each other. Especially the translation wheel 17 is integrally formed, preferably made Injected plastic.

Fig. 4 shows the motor vehicle lock 2 in the locked state. When switching on of the motor 5, the traction means 6 is aufgewikkelt directly on the motor shaft 8 and thereby unwound from the first winding area 18, whereby the Übersetzungsrad 17 is turned. This results in a winding of the output side Part of the traction means 6 on the second take-up area 19, whereby the desired operation of the pawl 4 and the drag lever 7 causes becomes.

The radius of the first winding area 18 is, in particular at least to the factor 2, greater than the radius of the second winding area 19. As a result the preferred reduction of Zugmittelbewegung is achieved.

Particularly preferably, the effective winding radius of the first winding region varies 18. In the illustration example, this takes place when turning the Übersetzungsrads 17 counterclockwise, resulting in a snail or spiral contour results. This variation, especially decrease or increase, the radius of the first take-up area 18 is a lateral guide the traction means 6 conducive, so that the traction means 6 on the motor shaft 8 only is wound in a helical or single layer.

Additionally or alternatively, by the variation of the radius of the first winding area 18 and / or the second winding 19, the reduction be varied, in particular so that starting from the locking state initially a large reduction - especially to overcome large stops or Haftkräfte - and then an increasingly smaller reduction - in With regard to a quick opening or unlocking - is realized.

In contrast to the deflection roller 12, the transmission gear 17 on the housing 13th the motor vehicle lock 2 rotatably mounted.

The axis of rotation 20 of the gear 17 preferably extends transversely, in particular perpendicular to the winding axis, here the motor axis 8, and / or to the movement or pivoting plane of the pawl 4 and the drag lever 7th

The provision - ie the unwinding of the traction means 6 - of the motor shaft. 8 is preferably again by means of the spring 14 or by other spring force after switching off the engine 5.

Basically, it is not necessary that the first, from the motor shaft. 8 to the first winding portion 18 extending part of the traction means 6 and the second, from the second take-up area 19 to the drag lever 7 erstrekkende Part of the traction means 6 come from one and the same traction means 6; of the first and second part of the traction means 6 can therefore be made of different pieces and / or consist of different materials and / or different Dimensioning, for example due to their different tensile load, exhibit.

Preferably, however, both parts of the traction means 6 are made of a single Zugmittelstück, in particular rope piece, manufactured. The traction means 6, the said First and second part, is therefore preferably formed in one piece. Accordingly, the traction means 6 on or in the translation wheel 17 from the first Winding 18 led to the second winding 19.

The free end of the second part of the traction means 6 is preferably positive and / or by means of a preferably lockable insert 21 on the pawl 4 or - as in the illustrated example - attached to the finger lever 7. Especially the insert 21 is molded directly onto the traction means 6.

Hereinafter, a preferred production will be explained in more detail with reference to FIG. 5.

Preferably, the traction means 6 is formed from a piece of material, the immediate is placed in an injection mold, so that at the same time the receiving part 9, the gear 17 and the insert 21 molded onto the traction means 6 and to be produced. At the same time this is a positive connection between the traction means 6 and the components, ie the receiving part 9, the translation wheel 17 and the insert 21, made. If necessary, can the traction means 6 od with a node. Like. Be provided, especially in the area the translation wheel 17 and / or in the region of its free ends to a to ensure secure positive connection.

The components are preferably initially over one after their preparation Web 22 connected to each other, in such a way that the traction means 6 reasonably is held straight or tight. This facilitates storage and the Handling up to assembly, as an unintentional twisting, tangling or even knotting the traction means 6 is prevented. During assembly then the Web 22 of the components, ie the receiving part 9, the translation wheel 17 and the insert 21 is released, and the traction means 6 can be used together with the Components are intended to be installed in the motor vehicle lock 2.

Since only one Zugmittelstück required in the proposed production is the production and assembly costs are low, since only the two Ends of the traction device 6 must be cut off.

Moreover, as Fig. 4 makes particularly clear, a largely free arrangement the axes of rotation possible and thus a total free arrangement possibility given the components.

A particularly robust embodiment of a motor vehicle lock 2 is in Figs. 6 and 7 are shown. Again, the above is basic Construction with lock latch 3, pawl 4 and 5 motor provided. Also is here the application of a flexible traction means 6 in the manner mentioned above basically provided.

It is essential in the embodiment shown in FIGS. 6 and 7 that The fact that the traction means 6 between the motor 5 and the pawl. 4 formed connection a direct connection without intermediate deflection o. The like. Is. That coming from the output shaft 8 of the engine 5 Traction means 6 thus passes directly to the pawl 4 and is at this attached. Starting from the locked state (Figure 6) causes actuation of the motor 5 a helical winding of the traction means 6 the output shaft 8 of the motor 5, until the unlocked or opened state or an optionally provided overstroke position of the pawl 4 is reached. Also Here, the pawl 4 is biased by a spring 14 in the reverse direction. at the spring 14 is a in the illustrated embodiment Leg spring.

The pawl 4 is a pawl axis 23 in all embodiments pivotable. In the embodiment shown in Figs. 6 and 7 is the Pawl 4 also equipped with an engaging member 24 which the Lock latch 3 locked in the locked state (Fig. 6). Is particularly advantageous the fact that the engagement member 24 comparatively close to the pawl axis 23 is arranged. As a result, the motor 5 is a comparatively low torque on the pawl 4 for lifting the pawl. 4 applied.

It is particularly advantageous if the engagement element 24 is comparatively close the pawl axis 23 is arranged and if at the same time the force application point the traction means 6 on the pawl 4 in a comparatively long distance is arranged by the pawl axis 23. Then that's about that Traction means 6 to be transmitted driving force particularly low.

With regard to the particular embodiment of FIGS. 6 and 7 shown Embodiment, in particular with regard to the particular embodiment of Pawl 4, is allowed on the by the applicant on 12 November 2004 at German Patent and Trademark Office filed application, the content of which is the subject of the present application in its entirety is done.

A particularly compact arrangement shows the motor vehicle lock shown in Fig. 8 2. Again, the basic structure described above is with latch 3, pawl 4 and (not shown) engine 5 realized. Furthermore, a flexible traction means 6 for opening the pawl 4 is also provided here. The pawl 4 is further pivotable about a pivot axis 23 and by means of a spring, not shown in the reverse direction (in Fig. 8 on the right) biased. The motor vehicle lock shown in Fig. 8 is in the locked Status.

It is essential in the embodiment shown in Fig. 8, the fact that the pawl 4 has a substantially cylindrical portion 25, wherein the cylindrical portion 25 is centered or eccentric to the pawl axis 23 can be aligned. In the embodiment shown in Fig. 8 the cylindrical portion 25 is centered to the pawl axis 23rd aligned. It is also essential that the traction means 6 for connecting the Motor 5 with the pawl 4 on the lateral surface of the cylindrical portion 25 is fixed and is deflected by the lateral surface. The arrangement is now made such that by the motor 5 via the traction means 6 pivoting the pawl 4 is effected.

With regard to the operation of the pawl 4 is in particular the fact advantageous that a provided on the pawl 4 lever o. The like. For connection the traction means 6 need not be provided. The task of such Lever assumes namely the cylindrical portion 25 of the pawl 4. Bei the centric orientation of the cylindrical portion 25 to the pawl axis 23 causes a constant, transmitted via the traction means 6 driving force over the entire adjustment of the pawl 4 a constant drive torque on the pawl 4. On the other hand causes the eccentric alignment of the cylindrical portion 25 to the pawl axis 23 a corresponding with the adjustment of the pawl 4 changing translation. This can, as described above, be particularly advantageous. It is allowed on it be pointed out that this pawl 4 has an engagement member 24, which is arranged comparatively close to the pawl axis 23, which As described above, leads to that for the actuation of the pawl 4 a comparatively low driving force is applied.

For the configuration of the cylindrical portion 25 of the pawl 4 are a Range of possibilities conceivable. For example, it may be a act narrow section whose width is just sufficient to the corresponding Winding or development of the traction means 6 on the pawl. 4 or to ensure the pawl 4. But it can also be provided that the cylindrical portion 25 substantially over the entire width the pawl 4 extends.

In both embodiments of FIG. 6,7 and FIG. 8, it is such that the Engaging portion 24 protrudes from the pawl 4 in the rest (in Figs. 6 to 8 out of the drawing). This is the engagement between the engagement element 24 and the latch 3 ensures.

For the special embodiment of the pawl 4 shown in Fig. 8 may also to the above-mentioned, by the Applicant to the German Patent and Trademark Office already filed application.

Of particular importance is finally the attachment of the traction means 6 am Housing 13, on the output shaft 8 and the receiving part 9 or on the pawl 4 or on the drag lever 7 to. Some options have been added already explained above. In summary, it should be noted that here all conceivable types of fastening are applicable. Examples include hanging, knotting, looping or clamping, as well as laser welding, gluing, overmolding or overmolding.
