Description

Motor vehicle door

The present invention relates to a motor vehicle door according to claim 1 and a method for fastening a deflection element according to claim 10.

Motor vehicle doors often have a door module on which various functional elements, such as speaker units or controls are included in particular for the power window devices.

In order to open and close a window, often elements are arranged on the door module, where by means of power transmission elements, such as ropes or wires, and with the aid of Umlenkblöcken or pulleys, a mechanism is provided to allow the opening and closing of the window. The deflection devices are usually provided on the door frame. These However, vehicle doors have the disadvantage that they are very expensive to manufacture.

An alternative is the attachment of Umlenkelemen- th means of a tab and / or a bag. In this case, a bag is arranged protruding from the door module, wherein the deflecting element is held between the door module wall and a flap wall. The disadvantage of such a solution is that the deflecting elements can only run substantially in the plane of the door module wall, which severely restricts the constructive possibilities.

One possibility for fastening a deflection element spaced from a door module wall is that the deflection element is riveted to a protruding part of the door module. However, this riveting is particularly difficult on a plastic door module. This is due to the lack of space for the counterpart of the

Riveting. Furthermore, the introduction of force into the door module is limited, which leads to an increased instability of the outstanding part of the door module.

Object of the present invention is to provide a motor vehicle door with a door module, which overcomes the aforementioned disadvantages.

The object is achieved by a motor vehicle door according to claim 1. Advantageous developments of the invention are described in the subordinate claims.

The motor vehicle door according to the invention has a door module which has a device for deflecting having movable power transmission elements and at least one deflecting element. Furthermore, the door module has a tab and / or pocket, in which the deflecting element can be stored. The tab is formed by two bearing points, which are spaced from the door module wall. The bearings have aligned recesses for receiving an axis for the deflecting element.

Due to the presence of two bearings, it is possible to choose the position of the deflector regardless of the position of the door module wall. Characterized in that the bearings have two aligned recesses for receiving an axis for the Umlenkele- ment, the inserted on an axis deflecting element can be easily inserted into the recesses, which greatly simplifies the installation of the deflector on the door module.

Advantageously, the deflection element, preferably a deflection roller, is rotatably connected to an axle. The axis is frictionally mounted in the recesses. Since the axle is frictionally mounted in the recesses, no signs of wear occur in the recesses. Due to a suitable choice of material of the deflecting element, preferably a deflection roller, wear phenomena between the axis and the deflecting element can be avoided.

It is particularly advantageous if the axis for fixing transversely to the direction of the aligned recess, d. H. along the direction in which the recesses are in alignment with each other, at least one collar. By means of the collar, the

Force fit can be achieved advantageous. there it is possible that the collar between the two bearing points is attached or, in the case of two collars, both lie outside of the bearing points and so a fixation is achieved. It is advantageous that the axis can not be vibrated out of the aligned recesses in the direction in which the recesses are in alignment with vibrations.

Particularly advantageous are the bearings with the

Door module materially connected. This has the particular advantage that during a manufacturing process of the door module, the bearings are molded or made of the same material. This represents a simplified approach, in particular with regard to the assembly of such a door module. Furthermore, the door module does not have to have bores with which the bearing points are connected to the door module. This has the consequence that in places where high voltages can occur, d. H. in the connection between the bearings and the door module, due to the cohesion an improved power flow can be achieved. This increases the overall stability of the bearing points or of the power transmission elements fastened to the bearing points.

Particularly advantageously, the bearing points are arranged on a projection, which protrudes from the door module. This has the advantage that the bearings can be made essentially straight. The projection thus forms the underlay for the application of the bearing points, which in this way can be applied particularly easily spaced from the door module wall. Due to the substantially straight execution of the bearings takes place again an improved flow of force through the bearings instead, and stresses that would occur without a projection, since the bearings would have curves or kinks are avoided. The advantage is an increased service life of the door module or the bearing points and a simplified manufacture and attachment of a power transmission mechanism.

The recesses are advantageously freely accessible in a direction transverse to the direction of the aligned recesses, preferably U- or V-shaped. Freely accessible here means in particular that the recesses are not a completely enclosed hole. In this way, the axis can already be applied with the attached deflection in the aligned recesses, which in turn has a simplified production result. For not freely accessible recesses, such as holes, the axis must first be inserted through a recess, through the guide roller and the second recess, which requires a lot of time.

The free accessibility of the recesses is particularly advantageous when the recesses each have at least one locking lug. By means of the latching nose, the introduced axis can be latched transversely to the direction of the aligned recesses. Distribution is that a once introduced axle for the fitter feel and audibly locks and the bearings can also be mounted so that the axis, which would fall out due to gravity, still remains in the recess.

Particularly advantageous is a force applied by the force transfer elements power flow on the Transmission element applied substantially in the direction of a closed part of the freely accessible recesses. This means that the axle by means of the force transmission elements in the recess in the direction transverse to the direction of the aligned

Recesses is held, which causes additional stability of the device.

Preferably, the door module and the bearing points are made of a plastic, preferably with additional fiber materials. The deflecting element is preferably made of POM and the axis is preferably made of a metal. The door module and the bearing points can be produced favorably from the same plastic, which is improved by additional fiber materials in its processing and stability. The advantage of a deflecting element made of POM is the largely wear-free nature of the plastic, which leads to a life-prolonging advantage, in particular in the case of the rotatable variant of the deflection roller. Axle pins can be made of metal, especially steel, with high precision.

By means of the motor vehicle door according to the invention with a door module, a method for fixing a deflecting element to a door module can be formulated. In this case, first the deflecting element is connected to the axle, so that the deflecting element is rotatably mounted. In a second step, the axle is inserted into the freely accessible recesses. Advantage of such a method is that a lot of time can be saved in the assembly of the deflection, which makes the production in particular cheaper and more efficient. Below, the invention and the method according to the invention will be explained in more detail with reference to some embodiments. Show it:

Fig. 5a further embodiment with inner door panel

In Fig. 1, a motor vehicle door 1 is shown, which has a door module 2, on which two inventive devices 3, 3 ¹ for deflecting movable power transmission elements 100 are arranged. The door module 2 in this case has a door module wall 20. Furthermore, there are two projections 21, 21 'on which the devices 3, 3 ¹ are arranged and which are connected to the door module in a cohesive manner. On the devices 3, 3 ¹ , a force transmission element 100 is arranged in the form of a rope. The devices 3, 3 'in cooperation with the power transmission element 100 are particularly suitable for a door lift mechanism.

In Fig. 2a, the device 3 is shown in a close-up. The essential elements in this case form the two straight running bearing points 51, 52, which each have a recess 61, 62 for receiving an axle. The spacing between the two bearing points 61, 62 is chosen so that a deflecting element in the form of a deflection roller 31 between see the two bearings fits and has little play. The bearings 51, 52 thus form a tab 5, in which the guide roller 31 can be arranged. It can be clearly seen that the tab 5 is spaced from the actual door module wall 20 and is arranged on a projection 21, wherein the projection is, however, formed on the door module. In this way, it is possible to choose the course of the power transmission elements so that the power transmission elements do not have to be arranged in direct proximity to the door module wall 20. Furthermore, two webs 53, 53 'are to be seen, whose distance from one another is selected so that a force transmission element, which is located on the deflection roller 31, exactly between the deflection roller and the web 53 bzv /. 53 'runs. As a result, the power transmission element has little play, which also has an advantageous effect on the assembly of the motor vehicle door according to the invention.

FIG. 2 b shows a frontal view of the device 3. From this representation it can be seen that the two webs 53, 53 'are arranged so that only a small distance exists between the deflection roller 31 and the webs 53, 53', so that a force transmission element 100 mounted on the deflection roller 31 is supported by means of the webs can be so that both downwardly hanging free ends of the power transmission element 100 are then brought into an operating position, as shown in the illustrated operating state of the power transmission element 100. Of course, even in the event that the ends of the power transmission element hang vertically downwards, ie the force transmission element 100 between the webs 53 and 53 'and the pulley extends, an operating condition be justified.

In the variant shown here is located in the recess 61 of the bearings 51 an axis 7, which consists of steel. In this case, the deflection roller 31, which consists of POM and thus is very resistant to abrasion, first attached to the axis 7 and then inserted the axis in the recess 61 and the recognizable from Fig. 2a recess 62. The recesses 61 and 62 are in flight. The axis 7 thus extends in the direction of the aligned recesses 61, 62nd

It can be clearly seen that the recess 61 is freely accessible at its upper end and substantially U-shaped. In this case, the recess 61 tapers from top to bottom, wherein two locking lugs 610 and 610 'form the narrowest portion of the recess, so that an introduced into the recess axis locked in its final position and no longer (in the orientation of Fig. 2b) can be moved up. This means, in particular, that the axle 7 can be removed only with great effort against an applied force F.

As can already be seen from FIG. 2a, the bearing points 51 and 52 are essentially straight. As a result, good power transmission to the projection 21 is possible. In the variant shown here, the bearing 51 projects beyond the projection and is connected to the door module by means of webs 510, which decrease in thickness from top to bottom. A force acting on the web 51 force F, which is applied via the power transmission element 100, via the webs 510th well derived in the plastic projection 21. there

R i TiH H τ_ ^p hp i ripπ 1.3 CTPr-PS t- PT i PrI RI and R 2 s tnf f cj πh i u s ssi it connected to the projection 21, consist of the same material, which is a plastic with Fasermateri- alien , and are produced in the same work process. A later molding of the bearings is possible.

FIG. 2 c shows a further possible variant of attaching a latching nose 611 in the recess 61. In this case, only one edge of the recess 61 on the locking lug, the other edge is substantially straight. The drawn axis 7 is also frictionally, as in the example in Fig. 2b, stored in the recess 61. By virtue of the fact that, due to the closed parts, i. H. The lower edge, the recesses formed suspension points for the axis are at the same level, no torque acting on the axis, as occurs in a known in the art riveting with only one bearing point. The single moment is generated by the deflection roller 31 and, depending on the force flow F applied by the force transmission element 100, applies a uniform load to the bearing points 51 and 52. Preferably, the force transmission elements 100 are applied so that the force flux F is directed so that the axis 7 is pressed onto the lower edge of the recess 61, as shown in the drawings.

In Fig. 3, the device 3 according to the invention is shown in a transverse view. It can clearly be seen that the door module wall 20 has a projection 21 on which the two bearing points 51, 52 are arranged. Also in this view, the two bearings 51 and 52 are straight down. The Extension of the bearing point 51 thereby represents the downwards running wa.nd 200 ÖΆT. wp.lche is part of the door module. Between the two bearing points 51 and 52, the deflection roller 31 rotatably mounted on the axis 7 can be seen. Furthermore, it can be clearly seen that, in the case of a force transmission element 100, a force flow takes place on the deflection roller 31 on the axle 7, which is mounted in the respective recesses 61 and 62 without any torque between the bearing points 51, 52.

In FIG. 4, the axis 7 has a collar 72, which is selected in its width so that it comes to rest substantially free of play between the bearing points 51 and 52 in the recesses 61, 62. A lateral pushing out of the axle pin in the direction of the aligned recesses is no longer possible. In essence, the guide roller 31 runs on the axis 7, which does not move. Alternatively, however, it would also be conceivable to connect the axle pin materially to the deflection roller 31 and to coat the recesses in such a way that abrasion of the plastic or of the plastic with fiber materials of the bearing points 51 and 52 is avoided.

Further exemplary embodiments are shown in FIGS. 5a and 5b. According to one of the previous embodiments, the axes 7 ¹ and 7 '' in the recesses 61, 62 of the bearings 51, 52 are held. In the figure 5a, the axis 7 'has a bore 71 with an internal thread into which a screw 8 can be screwed. The bore 71 extends along the aligned direction of the recesses 61, 62. Between an edge surface 72 of the axis 7 'and the screw head 81 of the screw 8 is a Door inner panel 9 is held, wherein the edge surface preferably extends transversely to the bore 71. The door inner panel has a corresponding bore 91, which corresponds to the diameter of the screw body 82. Furthermore, a washer 83 can be mounted between the screw head 81 and the inner door panel 9. As can be seen from FIG. 5 a, the edge surface 72 preferably terminates flush with the edge surface 520 of the bearing 52.

Alternatively, the axis may be formed such that it has an external thread. This is shown in more detail in FIG. 5b. The axis 7 '' has an extension 73 with an external thread. The extension extends along the aligned direction of the recesses 61, 62 and protrudes beyond the edge surface 520 of the bearing 52 addition. In this case, the diameter of the extension 73 is selected such that it is smaller than the diameter of the edge surface 74.

The door inner panel 9 with the bore 91, which corresponds to the diameter of the extension 73 is placed on the extension 73 of the axis 7 '' and then countered with a groove 11, wherein the extension 73, the bore 91 penetrates. Optionally, a washer 83 is disposed between the groove 11 and the inner door panel 9.

The connection between the inner door panel 9 and the axle 7 'or 7' ^■ can either be a connection carrying the door module or merely an additionally stabilizing connection. As an alternative to the force-locking screw connections described in FIGS. 5a and 5b, the connection between the axle and the inner door panel can also be made by means of rivet or Plug connections are made. Both in the rivet and in the connectors can be dispensed with an internal or external thread of the axis and it is achieved an additional positive connection. Thus, for example, the end of the extension 73 can be bent over to a rivet flange in order to hold the inner door panel between the Nietflansch (corresponding to the groove of Fig. 5b) and the edge surface 74.
