Description

The The invention relates to a cab for a truck, especially for a long-distance lorry The preamble of claim 1 and a method for producing Such a cab according to the preamble of claim 15th

cabs of trucks are regular with regard to a vertical longitudinal center plane constructed asymmetrically and equipped with a driver's side with the steering and the pedals and with a passenger side. Both on the driver side wall as well as on the passenger side wall is in each case a door opening attached, where mirror-image openable cab doors be used. Except for the modification for one However, left-hand drive or right-hand drive variant is thus the cab structure the body shell, especially in the area of the two opposite Cab doors symmetric. The cabs are common for a two-man operation and alternatively as a legal and left-hand drive vehicles with a driver's side and passenger side. For the variant right-hand drive and left-hand drive is usually on both sides a comparable or identical entry exists from for example ascent ladder, door, handholds available. For both entrances the same design criteria apply for the structure in terms of rigidity, (operational) strength and created the entry-level comfort.

From the DE 10 2006 010 183 A1 is a cab with a respect to a vertical longitudinal center plane asymmetric structure of the body shell is known in which the bottom is formed divided and offset in the driver side down and on the passenger side contrast is higher, which also the driver's seat and the passenger seat with each associated cab doors are arranged at different heights. The view from the door window of the passenger door on there road users, especially pedestrians, is here clearly limited, because the driver sits very low and the passenger door is mounted much higher in contrast.

task the invention is a cab for a truck, especially for a long-distance lorry, which is inexpensive to produce and easy for a Left-hand drive or right-hand drive variant can be modified, to which the visibility for a driver can be improved. Another object of the invention It is a method of making such a cab show.

The The object of the invention with respect to the cab with the features of claim 1 solved.

According to claim 1 is in a generic cab in opposite to the door cutout of a driver's door lying slice cutout of a disc side wall instead a side wall glazing attached to a door.

In order to is the trend for the one-man crew of a truck, in particular a long-distance lorry. Without a passenger is also a passenger door dispensable and can by a regularly much cheaper Sidewall glazing to be replaced.

In a particularly preferred embodiment of the disk cutout mirrored the size of the door opening and thus corresponds to a conventional passenger side wall door opening. Thus, such a cab is easy as a left or right hand drive variant can be produced, as here only on the specified driver side the driver's door and opposite in the corresponding Sidewall cutout to install the side wall glazing.

Particularly advantageously, the side wall glazing is designed as glued fixed glazing (ESG or alternatively plastic), which in addition to a good view further functions are possible:
The glued fixed glazing increases the structural rigidity as a thrust field, for example analogous to the windshield. In addition, with appropriate design of the glazing, the soundproofing and / or the thermal insulation and / or the burglary security can be improved and a weight reduction can be achieved.

In the usual way, the disk cutout is bounded to the front by an A pillar and to the rear by a B pillar of the cab body. In a preferred embodiment, the A-pillar and the B-pillar are connected approximately at half the height with a connecting element as a structural support. With such a structural support, a number of other functions can be fulfilled, depending on the circumstances and requirements and on its dimensioning:
As a longitudinal beam, such a structural support generally increases the structural strength in the pane cutout and, with appropriate dimensioning as a crash element, can specifically absorb and reduce crash loads in an additional crash load path. Furthermore, the structural support can be embodied as a visually appealing styling element in the region of the side wall glazing. In addition, the structural support as a base support for built-in or built-in or integrated functional parts, such as trays, containers, Air ducts, etc. manufactured and installed.

Possibly can also further structural support elements, in particular also as crash elements in the area and / or offset to the disk cutout and / or attached to the cab floor. In particular, can a longitudinal mounting bracket for a Provided arranged in the vehicle longitudinal direction sleeping berth become.

The relation between the side wall glazing and one or more structural beams may be different depending on the circumstances:
In a first embodiment, the side wall glazing runs without connection outside in front of a structural support.

alternative For this purpose, the side wall glazing preferably with an over the length of the structural support continuous adhesive bond be connected with this. This may possibly the structural strength and the crash behavior further improved become.

In Another alternative may be with the structural support as a frame part, a division of the side wall glazing in a upper frame field and a lower frame field. An upper glazing element and a lower glazing element may, optionally also be placed offset in the glazing level.

Especially Advantageously, the side wall glazing down to the ground the cab according to an entire door opening attached, since this advantageous for the driver's view, especially on lateral pedestrians, essential is improved. In the above division by a structural support in an upper frame and a lower frame can also optionally the lower frame field alternately through a panel, be covered and closed in particular made of plastic or metal. Thus, the cost advantages are compared here as well an otherwise openable passenger door achieved in conjunction with the increase in structural strength, Improving the visibility to the side down but will not receive anymore.

The Sidewall glazing may be in a pane cutout than conventional Door cutout directly on a door flange be glued. Alternatively, however, if necessary via a Adapter structure used in the door opening and on the Door frame is attached, an accommodation and a transition between the side wall glazing and the door opening respectively.

The Sidewall glazing is preferably as a continuous glass wall but can be used for splits and adjustments also be made of several individual glazing elements.

In a particularly preferred development is according to the door version even just an entry on the driver's side in front of or behind the front axle intended. These can also be corresponding opposite Entry formations are provided after a decision for a left-hand drive or right-hand drive variant with a Entry-level assembly on the driver's side to be supplemented. On the opposite side is the corresponding Shaping through a panel, in particular through a plastic panel covered to a closed outer skin surface. Instead of the entry-level assembly can advantageously a fender provided in lightweight construction with lower stiffness / strength requirements become. Further, by eliminating the entry a gain be gained in space, for example, with other components can be equipped. In addition, both when eliminating a Entry-level assembly and a corresponding cover as well With the side wall glazing, a favorable improvement in the CW value by reducing gaps and reducing the number of joints with more flexible design options connected to the Strak.

One Emergency exit is no longer possible with fixed glazing, However, with a conventional roof-lift system and / or by use of a releasably attached impactor be realized for a disk destruction.

The The object of the invention is with respect to the method the features of claim 15 solved. This is in the body shop a cab with two opposite door cutouts produced. After assignment of the driver's cab to a left-hand drive or right-hand drive variant is then in the door opening the fixed driver's side a cab door and opposite a fixed glazing used as a side wall glazing.

Based a drawing, the invention will be further explained. It demonstrate:

1 a schematic side view of a body of a truck with a cab with a side wall glazing;

2 a schematic sectional view taken along the line AA 1 ;

3 an alternative arrangement to 2 ;

4 a schematic sectional view taken along the line BB 1 ;

5 an alternative embodiment to 4 ;

6 an alternative embodiment to the 4 and 5 ;

7 an alternative embodiment to the 4 . 5 and 6 ;

7a an alternative embodiment to 7

8th a perspective view of a cab with side wall glazing with the distribution of crash load paths;

9 a schematic plan view of the interior of a cab; and

10 a schematic representation of the visibility of a cab with side wall glazing.

In 1 is a body 1 a left-hand drive truck with a cab 2 shown schematically. A perspective view of the cab 2 is in 8th shown.

Opposite to a driver sidewall 3 with a driver's door 4 ( 8th ) is in a disk cutout 5 a disk side wall 6 instead of a cab door, a side wall glazing 7 attached as glued fixed glazing. The disk cutout 5 corresponds in mirror image to the door cutout for the driver's door.

In 2 is in a schematic sectional view taken along the line AA 1 an A-pillar 8th and a B-pillar 9 shown with aligned flanges 10 and 11 with which the side wall glazing 7 over longitudinal adhesive beads 12 . 13 connected is. In addition, at the A-pillar 8th via another connecting flange 14 and a bead of glue 15 a windshield 16 connected.

In a similar alternative embodiment 2 is according to 3 between the side wall glazing 7 and the connecting flanges 10 . 11 an adapter structure 17 , shown here schematically as a sheet metal angle, used for adjustments.

How out 1 and 8th can be seen, are the A-pillar 8th and the B-pillar 9 about halfway through a structural beam 18 connected as a crash element. These are different embodiments in the 4 to 7 as sectional views along the line BB 1 shown:
In 4 is the structural support 18 designed as a tubular crash element and in the cab 2 close but without connection to the side wall glazing 7 arranged.

In the embodiment according to 5 is the structural support 18 as a rectangular tube with the same arrangement as in 4 without connection to the side wall glazing 7 educated. In the structural support 18 here is an air duct integrated with air outlet openings 19 for a disc ventilation (arrows 20 ) of the side wall glazing 7 ,

In the embodiment according to 6 is the structural support 18 designed as a flat rolled profile, which is a bond by a Kleberaupe 21 with the side wall glazing 7 is firmly connected.

In the embodiment according to 7 is the structural support 18 executed as a frame part of the side wall glazing and divides it into an upper frame field 22 and a lower frame field 23 each with connection flanges 24 and 25 , The upper frame field 22 and the bottom frame box 23 each with an upper glazing element 26 and lower glazing element 27 filled and connected by gluing. Instead of the lower glazing element 27 If appropriate, a panel, in particular made of plastic, could also be used. In a similar embodiment according to 7a is on the outside of the structural support 18 to the top a glass glazing 26a and down a plastic glazing 27a connected via a bond.

Out 8th It can be seen that during a crash load through the use of the structural support 18 in the side structure in addition to an upper and lower crash load path 28 . 29 another middle crash load path 30 is formed, so that external crash loads (arrow 31 ) are distributed evenly and effectively.

An emergency exit can here if necessary in addition to the driver's door 4 via a roof lift system 32 respectively.

In 9 is a top view into the interior of the cab 2 shown schematically with a front cab wall 33 and a rear cab wall 34 as well as with a driver's seat 35 on the driver's side. Opposite is the side wall glazing 7 indicated. In addition, here is a side member 36 a connection between the front cab wall 33 and the rear Cab wall 34 produced. This side member 36 can be used spaced from the cab floor, for example, as a longitudinal mounting bracket for a bunk or as a base support for other inputs and attachments. He also has here the functiom of a crash element and thus provides another crash load path in a frontal crash (arrow 37 ) or rear crash (arrow 38 ).

In 10 is a longitudinal section through a cab 2 shown. A sidewall glazing 7 is here in a preferred embodiment to the cab floor 39 pulled down, leaving a driver with an eye position at the point 40 according to the visual beam 41 has a wide field of view to the side down and, for example, a local pedestrian 42 able to see. On a standard passenger side door, the height of the parapet door is in the area of the location 43 so that thereby the angle of view laterally down much higher through the line of sight 44 is limited and possibly a pedestrian 42 can not be seen anymore.

How out 1 can be seen on the provided with the side wall glazing cab side an otherwise common entry area with a panel 45 , in particular closed with a plastic panel to a continuous outer skin surface.
