Description

Sliding door for a motor vehicle

description

The invention relates to a sliding door for a motor vehicle according to the preamble of patent claim 1.

Such a sliding door is movable by sliding along a vehicle body to open and close a door opening of the vehicle body can. For this purpose, it has a sliding door drive, in particular in the form of an electromotive drive with a downstream transmission, which, via a

Power transmission mechanism with a fixed, that is, not together with the

Sliding door movable part of the vehicle body is connectable. This may be, for example, a guided in a Bowden cable. This allows the adjustment forces generated by the sliding door drive between the sliding door and

Car body transferred to the desired relative movement of the

To produce sliding door with respect to the vehicle body, so causing a shift of the sliding door. Such a sliding door usually has other facilities for actuating a Verstellteiles, for example, a door lock for

Actuation of such lock parts, a locking or unlocking the sliding door effect, as well as a window lift for adjusting the position of an adjustable. Windowpane.

The invention is based on the problem to provide a sliding door of the type mentioned, which is characterized by an improved and variable mountability.

This problem is solved by the invention by providing a sliding door with the features of claim 1.

Thereafter, a fastened to the sliding door module carrier is provided, which carries at least part of the components of at least one other device for actuating a Verstellteiles next door to the sliding door, so for example components of the locking system (door lock and possibly a Türzuziehhilfe) and / or components of a window regulator for adjusting a windowpane.

The inventive solution integrated, modularized subsystems are created for sliding doors that can be pre-assembled outside the sliding door and check their function and can be attached to the sliding door as a completely prefabricated and pre-tested module.

In this case, the sliding door drive can either be mounted directly on the module carrier or, alternatively, connected only via the power transmission mechanism, for example in the form of a flexible shaft or in the form of a Bowden cable, with the module carrier.

If the module carrier carries a door lock as a further means for actuating an adjustment part, a corresponding lock carrier is provided on the module carrier, in particular integrally formed. The door lock can be stored for purposes of tolerance compensation in a direction displaceable on the module carrier. Furthermore, the lock carrier itself can be displaceable with respect to other areas of the module carrier, for example by the lock carrier is connected via a deformable portion with the other areas of the module carrier.

Insofar as the module carrier carries components of a window lifter for actuating an adjustable window pane as a further device for actuating an adjusting part, the adjusting drive of the window lifter and / or a guide rail for

Guide the window to be adjusted to be provided on the module carrier. Both Guide rails can be, in particular, a rail for guiding a lateral window edge of the window pane to be adjusted, wherein a corresponding guide channel for guiding the associated lateral window edge of the window pane is preferably arranged on a module support made of plastic. The guide channel is advantageously formed by a plurality in the adjustment of the window pane successively arranged Umgriffsbereiche, each embrace the associated lateral edge of the disk in a U-shape.

According to one embodiment of the invention, a further guide rail for guiding the window to be adjusted is provided, which can be arranged on a separate module carrier. According to a preferred embodiment is on the second

Guide rail slidably mounted in the adjustment of a driver, by the

Adjustment of the window lifter, for example via a flexible traction means, along the second guide rail is movable and which is connected to the window to be adjusted, so that upon movement of the driver to be adjusted

Window is taken.

In a combination of a plastic module carrier with a integrally molded thereon guide rail and another module carrier with a second guide rail, the second module carrier and the second guide rail advantageously made of a high strength material, especially steel, which on the one hand causes a stiffening of the door body and on the other hand an arrangement allows the second guide rail such that it carries a larger proportion of the disk load than the first guide rail. For this purpose, the second guide rail is arranged closer to the center of mass of the window to be adjusted, ie - along the lower edge of the window to be adjusted - closer to the center of the disk. The arrangement is preferably such that the second, high-strength guide rail carries at least 65% of the disk load.

The two modules can be combined prior to or during installation in a sliding door to form a unit that forms part of the wet / dry space separation of the Scheib door, so the vehicle interior facing the drying room of the vehicle outer space facing wet room. If the two module carriers are arranged and fastened separately to the corresponding sliding door with the components pre-assembled thereon, this allows a simplified assembly, for example by pivoting. Furthermore, deflecting elements for the sliding door drive and channels, securing and clamping elements for a traction means (rope) can be integrated in one or the other module carrier, which is coupled as a power transmission device with the sliding door drive or the adjustment of the window.

With a mounted in the mounted state laterally beyond the Türrohbau the sliding door section of the module carrier can also covering and guiding functions for the power transmission of the sliding door drive, for example in the form of a cable, take over.

Further details and advantages of the invention will become apparent in the following description of exemplary embodiments with reference to the figures.

Show it:

FIG. 1 shows a schematic view of a sliding door for a motor vehicle with an adjustment system arranged on the door inner skin of the motor vehicle door;

Figure 1 A is a section through a guide rail of the adjustment system of Figure 1;

Figure 2 is a view of a sliding door of a motor vehicle with an adjusting system arranged thereon;

Figure 3 is a preassembled on a module carrier adjustment system for a sliding door of a motor vehicle;

Figure 4 shows another embodiment of a preassembled on a module carrier adjustment system for a motor vehicle door.

1 shows a schematic side view of a sliding along a direction of displacement V sliding door of a motor vehicle. The sliding door comprises a door box T, which is provided on the inner side facing the vehicle interior with a large-area cutout A, and a subsequent to the door box K window frame R, which defines a closable by means of a window glass window F window opening O. The large-area cutout A of the inner skin of the door box K is covered by two module supports 1, 5, each of which carries part of the components of an adjustment system of the sliding door. This adjustment system comprises as components a sliding door drive 3 for sliding the sliding door along the displacement direction V, a window lift for raising and lowering the window pane F along an adjustment direction z and a door lock 100 for closing the sliding door.

The first module carrier 1 has on its lateral edge on the one hand a lock carrier 10 for receiving the door lock 100. In addition, the first module carrier 1 forms at its lateral edge a guide channel as a guide rail for a side window edge S1 of the window F to be adjusted, by a plurality in the adjustment z of the adjusting window F successively arranged Umgriffsbereiche 15, the window pane F in the area their U-shaped encompass lateral side edge S1, see Figure 1a. As a result, a defined guidance of the window pane F in the adjustment direction z is ensured.

The guide rail 11 is part of a window lifter for raising and lowering the window pane F, which additionally extends a second, in the adjustment direction z of the window F to be adjusted F and of the first guide rail 11 formed by the Umgriffsbereiche 15 of the first module carrier 1 perpendicular to the adjustment z spaced second Guide rail 2 has. At the upper and lower end of the two guide rails 11, 2 in the adjustment direction z, deflecting elements 1a, 1b and 2a, 2b are provided in the form of deflection rollers, by means of which flexible traction means 45 of the window lifter can be deflected in such a way that a respective section 130 or 140 of the flexible traction device 45 extends (for example in the form of a rope) along the respective guide rail 11 and 2 respectively.

With the respective along one of the guide rails 11, 2 extending traction means section 130 and 140, a driver 13, 14 is respectively connected, which is defined in the region of the lower edge of the disc U to be adjusted window pane F at this. In this case, the first guide rail 11 associated driver 13 is guided only loosely along that guide rail 11, while the guided along the second guide rail 2 driver 14 is positively and thereby displaceably z in the adjustment z with the second guide rail 2 is engaged, so on the associated guide rail. 2 is forced. The flexible traction means 45 is associated with an adjustment 4, which comprises a drive motor 41 and a drive 42 downstream drive 42, which, for example in a known manner via a cable drum, with the traction means 45 is in operative connection and this depending on the direction of rotation of the drive motor 41 along one or the other direction can move. As a result, the window pane F connected via the drivers 13, 14 to the traction means 45 is raised or lowered along its adjustment direction z, depending on the direction of rotation of the motor 41.

The adjusting drive 4 is arranged on a section 10a of the module carrier 1, which at the same time forms the lateral gripping regions 15 of the first guide rail 11 of the window lifter.

The first module carrier 1 further comprises a lock carrier 10 for receiving a door lock, which is fixedly connected to the module carrier 1, in particular integrally formed thereon.

Finally, a sliding door drive 3 is arranged on the module carrier 1, which comprises a motor 31 and a motor 31 downstream adjusting 32, which drives a traction means 35, the deflecting elements 3a, 3b in the form of pulleys to a non-movable together with the sliding door Area of a motor vehicle bodywork can be guided and fixed there, so that the traction means 35 serves as a driven by the sliding door drive 3 power transmission element for transmitting Verstellkräften between the sliding door and a stationary portion of the body of a motor vehicle. This makes it possible to generate a relative movement of the sliding door with respect to the motor vehicle body in the direction of displacement V. Instead of a flexible traction device and any other power transmission elements can be used, which are suitable for coupling the sliding door side arranged sliding door drive 3 with a stationary portion of the vehicle body.

With a laterally projecting beyond the Türrohbau the sliding door in the assembled state section 12 of the module carrier can also covering and guiding functions for the power transmission of the sliding door drive, for example in the form of a cable 35, take over.

The first module carrier 1 is preferably made of a material which is a one-piece integration of a lock carrier 10, lateral Umgriffsbereiche 15 for adjusting Window 3 and possibly of bearing elements for storage of transmission parts of the sliding door drive 3 and / or the adjustment drive 4 easier, ie in particular made of plastic or possibly a light metal.

The second module carrier 5 serves to accommodate the second in the adjustment z of the window pane F to be adjusted extending guide rail 2, which spaced from the second lateral edge S2 of the window F significantly closer to the center of gravity, ie - viewed transversely to the adjustment z along the lower edge of the disc U - clearly closer to the center of the window F lies. The second guide rail 2 therefore carries in operation of the window lifter as on slamming the corresponding vehicle door a much larger proportion of the disk load than the integrated in the first module carrier 1 guide rail 11. Advantageously, the arrangement of the two guide rails 11, 2 such that the second guide rail 2 at least 60% and the first guide rail 11 receives at most 40% of the weight of the window pane F to be adjusted. Accordingly, the second guide rail 2 advantageously consists of a correspondingly more stable, firmer material than the first guide rail 11, that is to say made of steel.

The associated second module carrier 5 is advantageously also made of metal, in particular steel, so that it contributes to the stiffening, in particular (crash resistance) of the door body.

Both Moduiträger 1, 5 together completely cover the cutout A on the inside of the door box K and thus ensure a seal of the drying room with respect to the wet room of the sliding door. As a drying room while the one room is considered, which is located on the side facing the vehicle interior of the sliding door, while the wet room is located in front of the outer space facing side of the door inner skin.

The two module carriers 1, 5 can be connected to one another in the installed state on the one hand in their overlapping region L; On the other hand, there is a connection between the two modules of the adjustment system, namely the components of the adjustment system arranged on the first module carrier 1 and the components of the adjustment system arranged on the second module carrier 5 via the traction means 45 of the window lifter. The provided at the upper ends of the guide rails 1, 2 deflecting elements 1 b, 2 b in the form of pulleys are also attached to the parapets of the sliding door, so that forces acting there of the traction means 45 could be introduced directly into the vehicle body. The lower deflecting elements 1a, 2a in the form of deflection rollers are in contrast in Ausführungsbeispie) attached to the respective guide rail 11 and 2 and the associated module carrier 1 and 5 respectively.

FIG. 2 shows a modification of the arrangement from FIG. 1, in which the first module 1 again has an integrally formed first guide rail 11 which is arranged successively by a plurality of the window pane F to be adjusted in the adjustment direction z and a lateral pane edge S1 of the window pane F to be adjusted encompassing Umgriffsbereiche 15 is formed. On the first module carrier 1, a lock carrier 10 is formed, which carries the door lock 100.

In contrast to the embodiment shown in Figure 1, however, the sliding door drive 3 is not arranged on the first module carrier 1, but is connected to this only via a force transmission element formed by a flexible traction means 35. The sliding door drive 3 comprises a drive motor 31 and a downstream gear 32 and a mounting flange 33 with a plurality of fastening points 34, via which the sliding door drive 3 is attached directly to the door inner skin I of the sliding door.

In contrast to the adjustment system illustrated in FIG. 1, the sliding door drive 3 is thus not fixed directly to the first module carrier 1, but the sliding door drive is connected to the module carrier 1 only via the force transmission element in the form of a traction means 35. However, this also allows the pre-assembly of a module consisting of the window support 11 integrally formed on the module carrier 1, the door lock 100 fixed to the lock carrier 10 of the module carrier 1 and the sliding door drive 3 connected to the module carrier 1 via the flexible traction means 3. The connection of the flexible traction means 35 with the module carrier 1 takes place via the provided on the module carrier 1 deflecting elements 3a, 3b in the form of pulleys around which the driven by the sliding door drive 3 flexible traction means 35 is guided. Zugmittet 35 is preferably performed in at least one Bowden sleeve, which supported on the one hand on the sliding door drive 3 and on the other hand on the module carrier 1 (hung or otherwise fixed), see Fig .. 3 Accordingly, the first module carrier 1, on the one hand, and the sliding door drive 3, on the other hand, are fastened independently of one another to the inner door skin I of the sliding door. The attachment of the first module carrier 1 to the inner door skin I via fastening means which pass through the axes of the provided on the first module carrier 1 deflecting elements 1a, 1b in the form of deflection rollers. The attachment of the sliding door drive 3 takes place in contrast in the manner described above via fastening means which pass through the provided on the mounting flange 33 of the sliding door drive 3 attachment points 34 in the form of mounting holes.

The second guide rail 2 of the window lifter is also fastened to the door inner skin I by fastening means which pass through the bearing shafts of their deflecting elements 2a, 2b in the form of deflection rollers.

At the door inner skin I recognizable mounting holes are subsequently covered to create a dense wet / dry space separation.

In the embodiment shown in Figure 2 is for the sake of simplicity, a part of the components of the window lifter, namely its adjustment, the flexible traction means driven therefrom and the guided by means of the traction means driver not shown. For this purpose, reference is made to the illustration in Figure 1.

In the embodiment of an adjustment system illustrated in FIG. 3, a lock carrier 10 is formed on a module carrier 1 ', on which a door lock 100 is mounted so as to be longitudinally displaceable, so that tolerances can be compensated for when the module is installed in a sliding door.

Further, two deflecting elements 3a, 3b in the form of deflection rollers are rotatably mounted on the module carrier Y, which serve to deflect a formed by a flexible traction means in the form of a cable power transmission element, which is in operative connection with the gear 32 of a sliding door drive 3. The transmission 32 is in turn assigned on the one hand a drive motor 31 and on the other hand provided with attachment points 34 in the form of mounting holes mounting flange 33 through which the sliding door drive 3 is fastened to a subframe 6 bar.

The module carrier 1 'with the lock carrier 10 and the door lock 100 mounted thereon and with the deflecting elements 3a, 3b and the flexible traction means 35 hereby connected sliding door drive 3, in turn, forms a preassembled module which can be fastened to a subframe 6 of a sliding door via attachment points 16 provided on the module carrier 1, wherein - as described - an additional independent attachment of the sliding door drive 3 is provided via its mounting flange 33.

The traction means 35, which is in operative connection with the sliding door drive 3, is guided in the region between the sliding door drive 3 and the module carrier V in Bowden shells 36, which are fixed, for example suspended, on the mounting flange 34 of the sliding door drive 3 and on the module carrier 1 '; As a result, a connection between the module support 1 ¹ and sliding door drive 3 is created, which allows a pre-assembly of the sliding door drive 3 on the module support 1 'before the module support V and the sliding door drive 3 are determined via the attachment points provided for 16 or 34 on the subframe 6 of the door inner skin.

The components which can be combined on the module carrier 1 'into a preassembled adjustment system also include a door inner opener 12, which is connected to the door lock 100 via a force transmission element 120 in the form of a Bowden cable. On the subframe 6 of the sliding door, a receptacle 62 is provided for the door inner opener 12, so that it can be used in the mounting 62 of the module carrier V and the components 3, 3a, 3b, 12, 100 pre-assembled thereon.

In the embodiment of an adjustment system for a sliding door shown in Figure 4, a module support V on a lock carrier 10, on which a door lock 100 along a first direction r slidably or elastically movably superimposed and the mounting points 16 in the form of mounting holes for attachment to a Aggregate support 6 is provided a sliding door.

The lock carrier 10 is integrally connected via two flexurally elastic web-like portions 13 with a receiving portion 10 a, on which a gear 37 of the sliding door drive 3 is mounted. The receiving region 10a may have housing parts for mounting gear elements of the transmission 37. The flexurally elastic portions 13 allow for purposes of tolerance compensation, a relative movement of the lock carrier 10 with respect to the receiving area 10a along a direction z, which is oriented perpendicular to the direction r, along which the lock 100 slidably supported on the lock carrier 10.

The transmission 37 associated with the motor 31 of the sliding door drive 3 is disposed outside of the receiving area 10 a and separately fastened to the subframe 6. It is connected via a flexible shaft 36 with the gear 37 and thereby forms a part of the lock carrier 10 and on this integrally molded receiving portion 10a preassembled module.

The gear 37 of the adjusting drive 3 drives an output element 38 in the form of a gear, which in turn is in engagement with an internal toothing of a rotatable cable drum 39, which during operation of the motor 31 of the adjustment 3 via the flexible shaft 36, the downstream transmission 37 and the Output member 38 is rotated and is wrapped around a power transmission element 35 in the form of a cable, which is operated upon rotation of the cable drum 39 to move the associated sliding door.
