Description

The The invention relates to a door guide of a vehicle according to the preamble of claim 1 with a rail, comprising a first management area and another management area, by means of which means for guiding a door along the Profile rail can be performed. The invention further relates to a method according to the preamble of the claim 14 for producing a profiled rail for guiding a Door of a vehicle, by means of which means for guiding the door can be guided.

Out In practice, such door guides are known especially in motor vehicles, with sliding doors equipped for entry and exit of persons. These sliding doors often with suitable guiding or holding devices guided in a one-piece guide rails, which is attached to the vehicle body. In particular, a bent Curved portion of a one-piece rail or Guide rail poses problems for guide means, such as rolling a roller carriage, a door, since Regions of the curvature section with respect to the production When bending the profile rail, tie it in or bend it up can, so far with very high manufacturing tolerances had to be worked to a reasonably smooth Running of the guide means, in particular in the curvature section the rail, to ensure. to Production is the one-piece rail in a combination made of roll and stretch bending in shape, with stretch bending caused deformations on the profile or guide rail often have the result that the guide means from a too far bent profile or guide rail out jump or in a too tightly constricted area of the curvature section can clamp. To this To prevent roll bending with a relatively generous Measurement, a so-called Vorhaltemaß, worked, which is designed such that in any case at least one terminals the guide means is prevented. However, this has the negative consequence that in predominantly straight educated Sections between the guide means and the rail there is a very big game, so it during the opening and closing of a door can often come to a very troubled run the door which in turn quickly at least a mediocre Quality impression can arise.

DE 20 2005 004 059 U1 shows a guide system for a sliding door, in which a roller carriage is mounted and guided in a designed as a profile rail guide rail with a horizontally mounted guide roller or support roller and with a vertically mounted guide roller. For this purpose, the roller carriage can move along the guide rail so that the sliding door can be pushed back and forth in a translational manner along a substantially horizontally extending guide axle on a vehicle body, even when the guide rail is curved.

It object of the present invention, a door guide, in particular their guide rail, indicate with the a guide made the door safe and comfortable is.

These Task is by a door guide with the features of claim 1 or of a method having the features of the claim 14 solved.

By doing the rail of the door guide along her Longitudinal division is divided into two, can be more advantageous Way manufacturing tolerances reduced with respect to the rail which, on the one hand, increases the guidance accuracy the entire door in the door guide improved and on the other hand, the quality impression of the whole Door kinematics is improved.

With the term "at least two parts" is present described that the rail of preferably two components or more components exists on which guide means a door can be guided. Ideally In this case, a first component forms the first guide region and a second component the second guide portion of Rail. As a result, the present rail differs from conventional one-piece profiled or guide rails, as they consist of at least two guide rails put together.

Of the The term "rail" describes here that component of the door guide which on a vehicle body arranged approximately horizontally centered on the vehicle can be. Preferably, the rail is in the area of the actual Door opening through which people pass through the vehicle can get on or off, bent, so that Guide means at the door first in a straight Thread inlet section of the profile rail and then over a bent curved portion of the rail in a straight trained longer running section of the rail can reach.

The Terms "guidance areas" of the profile rail describe present areas of the rail, on which guide means a door, in particular the vertically mounted guide rollers the door, guided along the longitudinal extent of the rail can be.

Favorable Way, with the invention, at least two-part rail the components, from soft the at least two-part rail formed or put together is to be manufactured with manufacturing methods, by means of which lower manufacturing tolerances can be realized. Due to this, the present rail ensures an improvement of the guidance accuracy of the guide means of Door.

The Profile rail can be made constructionally particularly simple, if the first guide area is an upper guide rail the profile rail has.

has beyond that, the more leadership one lower guide rail of the rail on, can the guide areas of the rail particularly structurally simply be provided.

With the term "upper guide rail" is a independent component of the rail described. Accordingly describes the term "lower guide rail" a another independent component of the rail, which different from the upper guide rail.

Preferably be at the top guide rail guide rollers a guided carriage, which in essence rotate vertically aligned axes of rotation. At the lower guide rail By contrast, preferably guide rollers or support rollers guided along the longitudinal extent of the rail, which about substantially horizontally oriented axes of rotation can rotate.

A particularly advantageous embodiment provides that the first guide area a first guide rail and the further management area another guide rail having, wherein the two guide rails with each other are connected. Both guide rails can be separated make much easier and with lower manufacturing tolerances. Then they become at least two parts Rail connected together, giving an exceptionally precise Profile rail can be produced.

Become the individual guide rails together to form a profile rail Guided, the individual guide rails be made simpler in terms of their geometries, which Required manufacturing tolerances much easier and more accurate can be complied with.

Include the first guide region of the rail a first Leg of the door guide and the other guidance area the profile rail another leg of the door guide, wherein the two legs with each other at mutually facing ends connected, the two guide rails the present rail particularly constructively together be joined.

The Profile rail can with regard to their two guide rails be built particularly stable when the two facing each other Ends of the legs are arranged overlapping.

It It is understood that the guide rails of the rail can be connected in different ways. Particularly durable and stable can guide rails be joined together when the guide rails the rail welded together or with a connecting part are. The connecting part may also be the bodywork of a vehicle be.

Cumulative or alternatively, the guide rails of the Rail to be screwed together and / or riveted. Become the guide rails screwed together and / or riveted, They can be advantageously during the assembly immediately be attached directly to a vehicle body.

Especially The first management area can be with good Manufacture manufacturing tolerances when a first guide rail the rail is a thermoformed component.

Preferably is the first guide rail of the rail essentially C-shaped. As a result, for example two horizontally oriented guide rollers at least be supported on a leg of the first guide rail.

About that In addition, it is advantageous if another guide rail the rail is a rolling and stretch bending component. For example the second guide rail has a simpler geometry, so that they are advantageous by means of a roll and stretch bending process can be produced.

Preferably is the other guide rail of the rail essentially L-shaped. For an L-shaped geometry given manufacturing tolerances can be more easily met.

The object of the invention is also achieved by a vehicle, in particular by a motor vehicle, having a door which can be pushed back and forth along a body for opening or closing, in which a door guide according to one of the explained features is designed.

Further Advantages, objects and characteristics of the present invention result from the following description of a preferred embodiment and from the dependent claims.

The Invention will be described below with reference to the appended Drawings on the basis of a preferred embodiment the invention further explained.

1 schematically shows a perspective view of a preferred embodiment of a two-part along its longitudinal extension rail with an upper and a lower guide rail.

2 schematically shows a cross section of the rail 1 ,

In the 1 and 2 shown rail 1 serves to guide not shown here in detail guide means of a motor vehicle sliding door (not shown here) and extends substantially axially along a main sliding direction 2 the sliding door, not shown here. The two-part profile rail 1 has a straight inlet section 3 on, by means of a curved portion of curvature 4 in a turn straight sliding section 5 passes.

In addition, the two-part rail has 1 a variety of mounting holes 6 (numbered here only as an example) on which the two-part rail 1 by means of suitable fasteners with their back 7 can be attached to a motor vehicle body.

The two-part profile rail 1 further comprises a first guidance area 8th and another leadership area 9 , By means of which here the guide means not shown in detail, in particular guide rollers of a guide or roller carriage (not shown here), on the two-part rail 1 can be performed.

Here is the two-part rail 1 with an upper guide rail 10 , which is the first management area 8th provides, and a lower guide rail 11 , which the further guidance range 9 provides equipped. The upper guide rail 10 is a thermoformed component 12 and is formed in cross-section C-shaped. Opposite is the lower guide rail 11 a roll and stretch bending component 13 and is formed in cross-section substantially L-shaped.

The upper guide rail 10 has two substantially the lower guide rail 11 facing thighs 14 and 15 on, where it is at the thigh 14 around an upper guide leg 14 the two-part rail 1 and at the thigh 15 around an upper guide and connecting leg 15 the two-part rail 1 is.

The lower guide rail 11 also includes two legs 16 and 17 , where the thigh 16 a lower guide leg 16 and the thigh 17 a lower connecting leg 17 the two-part rail 1 is.

The two connecting legs 15 and 17 the profile rail 1 overlap in a connection area 18 in which they by means of a variety of riveted joints 19 (here only exemplified and numbered) are attached to each other, so that the two guide rails 10 and 11 are firmly connected. The upper guide rail 10 is here with her upper connecting leg 15 on one of the back 7 facing away from inside 20 of the lower connecting leg 17 nestled.

Due to the two-part design of the rail 1 can the two management areas 8th and 9 the profile rail 1 be made and shaped independently of each other, so that in the manufacture of the guide rails 10 . 11 only much simpler geometries must be considered so that much better manufacturing tolerances can be achieved.

Especially with a horizontal dimension 21 a smaller profile rail opening 22 on the upper guide rail 10 a tolerance of less than 1 mm can be maintained compared to tolerances of 1 mm for one-piece profiled rails. In particular, with respect to a bending operation on the upper guide rail 10 Tolerances smaller than 0.5 mm and in terms of positioning and welding also achieve a tolerance of less than 0.5 mm. In addition, the risk is reduced that the smaller profile opening 22 in the production of the upper guide rail 10 constricting critically. in particular in the bent portion of curvature 4 As a result, the guide means of the sliding door can be performed much better and more accurate, so that the risk is substantially reduced that the guide means in the rail 1 clamp or slip out of this.

With regard to a vertical dimension 23 a larger profile rail opening 24 It is also possible to achieve an improved tolerance of less than 1 mm compared to a conventional tolerance of 2 mm to 2.5 mm, whereby in particular also with regard to a bending process on the lower guide rail 11 Tolerances less than 0.5 mm and down visibly positioning and welding can also achieve a tolerance of less than 0.5 mm. Advantageously, it can be avoided in particular that the larger profile rail opening 24 in the manufacture of the rail 1 bends up.

Regarding the total height 25 It is also possible to achieve an improved tolerance of less than 0.5 mm compared to 0.9 mm to 1 mm for one-piece profiled rails.

The profile rail opening 24 can by a relative displacement of the two guide rails 10 and 11 be adjusted to each other very precise.

Due to the reasons mentioned above, the sliding door on the two-part rail 1 be performed much more accurate, in particular a game, for example between guide rollers and the two-part rail 1 significantly reduced. As a result, the noise level can be further advantageously reduced so that a much better quality impression is created. Last but not least, the feel of the sliding door can in principle be improved by the improved guiding behavior of the present two-part profile rail 1 be improved.

Be the top guide rail 10 and the lower guide rail 11 For example, by means of spot welding connected to each other, the two-part rail 1 be attached as a compact mounting part to a vehicle body.

Be the top guide rail 10 and the lower guide rail 11 For example, bolted together, could screwing with a mounting of the rail 1 be combined on the vehicle body. This means that the two guide rails 10 and 11 be positioned on the body and can be connected by means of the fittings both together and simultaneously with the vehicle body.
