The rear wheels have an axle bolt (28) with swing bearing (30) which has a ball-shaped inclined joint bearing (32) and swing tube (29) holding the axle bolt and inclined bearing. The swing tube has a bearing (34) correspondingly adapted to the inclined joint bearing and seated in a bearing seat (35) which easily adapts to the swing tube.

Description

The invention relates to a Innenlader for the transport of large areas or large-volume transport goods, especially flat glass or precast concrete, the connected to a tractor unit via a pin connection and the via on the axles of the rear wheels and airfeed acting on the tractor unit bellows from the low loading position to the higher transport position and vice versa is raised or lowered, the rear wheels with the axle swivel via an axle bolt integrated in an axle bracket with a specific one Wheel camber and wheel toe-specifying swing arm bearings.

Such inloaders are used primarily to transport large flat glass panes, which, of course, must be specially secured and arranged to prevent damage to avoid during transport. This flat glass is in A- or L-shaped Transport frames housed and set so that the individual panes at Transport are kept in such a way that damage and therefore not the smallest scratches occur. Glass panes of approximately the same weight are placed on both Support surfaces of the A-shaped transport frame set up, then in an inloader pushed and brought to the destination by tractor unit. The corresponding transport frame and vice versa also the chassis of the Innenlader have corresponding side members, so that when lifting the chassis of the Innenlader automatically lifted the transport frame and then ver will drive. The air suspension bellows assigned to the chassis, which had previously been relieved, again pressurized with compressed air, so that the Chassis, which is connected to the rear wheels via triangular swing arms is raised accordingly and the transport frame is lifted with it. Such inloaders are known for example from DE-OS 35 07 587. With the well-known inloaders the rear wheels are held over the triangular axles, which in turn are mounted on a swivel bearing in the chassis. This swivel bearing or swin The bearing is held at the end area via a counter plate, which is secured with eight screws is screwed. This counter plate can because of the small available  Space can only be dimensioned relatively small. The one over the swing arm lateral forces that occur can thus lead to a displacement of the bearing plates, so that at least the toe-in and toe-out are subject to constant change. For a camber change must wedge between the bearing plates at the appropriate place washers are underlaid, which also do not contribute to the permanent fixed bearing seat carry. After every lane or camber change, the bearings must be used for safety reasons plates are also welded together at several points after screwing will. The effort with this version is very high and the result achieved for Track and camber relatively imprecise.

The invention is therefore based on the object of an inloader with Easy to create adjustable swing arm bearing secured against load.

The object is achieved according to the invention in that the wings storage via a ball-shaped angular contact bearing and an axle pin and oblique swivel tube that receives the steering bearing, which is connected to the swivel joint bearing Correspondingly shaped bearing with a bearing fit on one side of the Swingarm tube is arranged to be interchangeable.

In this swingarm tube are slide bearings on both sides, which here as Angular contact bearings are provided. This allows the axle swing arm in front Swing the area seen without any problems and thus the swinging up and down of the inside loaders or the rear wheels. Because on the one hand the Angular contact bearings correspondingly reproduced or shaped accordingly receives an interchangeable bearing fit, depending on the need Fit bearing fit are used, which changes in the camber and in the Wheel toe-in can be compensated for or even specifically generated. With the basic leadership is this bearing or the bearing fit is symmetrical. Here through results if all other bearings are manufactured and used correctly are the previously mentioned track dimensions in camber toe and toe. Will be at night measurements deviations found on the rear wheel or on the rear wheels, so the described fit by the appropriate dimensions or shape  pointing bearing fits replaced. This is the first time that the Easily and securely adaptable, indeed practically infinitely variable, to the respective needs to specify a clear swing arm bearing. The work required for this is extremely one to perform easily and with little effort, which will be discussed in more detail later will go. Another advantage is that with this relatively simple setting a very high accuracy can be achieved because by changing the bearing fit zes exactly the intended or desired seat can be achieved.

After an expedient embodiment of the invention it is provided that the Bearing fit is pressed into the swingarm tube. This facilitates assembly in the special during final assembly, ensures a precise fit of this part and enables also a redissolution if this is necessary due to re-measurements or proves appropriate.

To also implement a variety of different settings can and thus allows a more or less stepless adjustment the invention proposes that a set of different bearing fits is provided, one of which each specifying a specific wheel toe-in and / or a specific wheel camber forms is. These individual bearing fits can be appropriately identified as who that the fitter can easily see which of the different bearing fits ze is needed. For this purpose, it is conceivable that the bearing fits, d. H. the corresponding Rings are color-coded accordingly.

To both the assembly and disassembly of the bearing fit or To facilitate the entire facility, the invention provides that the bearing fit as the bearing-receiving cup-shaped ring is formed, in the bottom part of which Recess for the axle pin is provided. This special training gives the Possibility to loosen and move the axle bolt first and then use a suitable device to push the cup-shaped ring out of its seat, with which the remaining parts of the bearing are then loosened so that they are light are removable from the axle bracket. At the same time, such a pot-shaped Ring also easier to assemble because it does not tilt or press in  otherwise can move.

Even with the heaviest loads, for example when driving through tight curves with more or less high speed is an impairment once set swing arm storage excluded because according to the invention the swing has a ring seat supporting the bearing fit. It goes without saying that the features mentioned above also contribute to this, the cup-shaped Ring fits exactly into the ring receptacles, so that it passes through the swine at the same time is fixed and stored almost all around. The ring holder also has the Advantage that both when dismantling and when assembling a guide for the component to be used is specified. Because with an easily replaceable part can be worked on welding, shooting and. who waives which again has the advantage that there is a delay due to such processing cannot adjust. Dismantling, i. H. especially the loosening of the axle bolt is facilitated by the fact that he with the joint approach of the angular contact bearing on a Side of the swingarm tube detachable via a lock nut and on the other side is connected via a support ring with anti-rotation lock. The security For its part, the working mother expediently uses a pen or the like against unconscious or unwanted loosening secured so that this must first be removed before the Locking nut on the thread of the axle bolt is unscrewed. Then he can Axle bolts can be moved without any problems, especially after a training course Invention of the axle bolt after loosening the lock nut in the Swing arm tube is stored. This is also possible because on the opposite Side there is no direct connection of the axle bolt; rather through the Support ring or with the support ring pushed out of the swingarm tube, up to the opposite side of the cup-shaped ring of the bearing fit is free, so that these parts of the bearing can be removed with a tool. After The axle pin is then measured and inserted again pushed back, supported accordingly on the opposite side and over the lock nut ultimately set after the rest of the parts such as as the angular contact bearing and the bearing are replaced.  

To protect the security pattern, it is provided that the joint approach is a Has locking nut receiving trough, which is releasably connected to it whose screw plate can be covered. This is also a protection for the ent speaking threaded end of the axle bolt created and a total given smooth surface, which is ultimately advantageous for overall operation can work.

In order to measure the necessary setting in the widest possible range Chen, it is advantageous if the swing arm joint in the area of the transition approach / angular contact bearing a ring-shaped interruption to the swing arm attachment having. This allows a wide range by replacing the angular contact bearing or the bearing fit practically any correction to be made to be able to set a proper camber or a toe-in and toe-out.

To protect the entire swing arm bearing, it is advantageous if a Interruption of the swingarm tube covering, pushable trained Ab sealing ring is provided, which is releasably connected only to the rocker tube. In order to this sealing ring remains when you remove the joint approach and the bevel Steering bearing connected to the swingarm tube, simply by the swingarm tube attachment is deducted with the corresponding parts. This swingarm tube approach is used correct seat, however, also covered by the sealing ring, so that here the desired Ab sealing effect is ensured. The setting in the already mentioned wide range is thus secured, it is further advantageous if the swing arm extension in Cover area through the sealing ring is equipped with a V-ring that the thrust wall of the sealing ring is arranged rubbing. Through this special Arrangement of the V-ring is the advantageous and also in this critical area desired seal secured, even if through the appropriate changes the fall or lane had to be changed over a large area.

The invention is particularly characterized in that an internal loader with a swing arm bearing is created that can be easily and safely installed and which is adjustable in a wide range, if not infinitely adjustable. To  are only a few parts to be solved and disassembled, in order to then give way here term fit fit to be replaced with one that has the desired dimensions corresponds or specifies this. Another advantage is that this camp fit is so arranges and is designed so that it can also withstand high loads without that problems can arise when driving. By placing several corresponding ring shaped bearing fits can be kept practically in any workshop Agile adjustment can be made, these relatively small components too can be held in the toolbox by the vehicle itself.

Further details and advantages of the subject matter of the invention result from the following description of the accompanying drawing, in which a preferred Embodiment with the necessary details and items shown is. Show it:

Fig. 1 is a inloader in side view,

Fig. 2 shows the suspension of a rear wheel with the axle swinging arm and air bellows in side view,

Fig. 3 shows a swing arm mount in section and two zero positions,

Fig. 4 is a partial view of FIG. 3 with the position changed and

Fig. 5 shows a cross section in the region of the bearing fit.

The Innenlader 1 and the tractor unit 2 are shown in Fig. 1 in the transport position. This means that the rear suspension of the Innenlader 1 and the front platform 3 have been raised here by moving the fifth wheel plate 4 over the air suspension, which is described in more detail below. Instead of the displacement of the saddle plate 4 , the arrangement of air bellows, hydraulic likaggregaten or the like is also possible here.

The Innenlader 1 is connected to the tractor unit 2 via the pin 5 , which is assigned to the fifth wheel plate 4 . This saddle plate 4 is in the longitudinal direction 6 of the chassis 7 and thus also the corresponding support bracket 8 displaceably angeord net, as explained above, and wedge-shaped.

With reference to FIG. 1 it is clear that a charge may be transported, for example in the form of respective flat sheets of glass readily because these charge accommodating longitudinal support member 9 has sufficient ground clearance. The rear wheels 10 , 11 of the Innenlader 1 are arranged in the rear region of the Innenlader 1 , while the front platform 3 of the Innenlader 1 is also supported on the tractor unit 2 .

The load is not visible in Fig. 1 because the tarpaulin 12 of the Innenlader 1 is closed. The loading space for the flat glass extends, for example, from the rear door 13 to approximately the height of the control box 14 . The rest of the area, ie in particular the area above the front loading platform 3, is available for the transportation of other things, in particular the floor covering to be carried by the vehicle and other things. The fact that a corresponding Bo denab Cover is taken and the required cargo space is also available during the trans port of flat glass, it is possible to create space for return freight by folding the trans port frame.

According to FIG. 2, the rear wheels 10 , 11 are pivotably mounted in axle arms 18 in the rear region of the interior loader 1 or the chassis 7 . The triangular axle swing arm 18 is held in the predetermined position on the one hand by the air bellows 19 and on the other hand by the wheel axis 20 and the pivot axis 21 . The position of the axle rocker 18 is changed by the air bellows 19 , which acts on the extended arm 22 of the axle rocker 18 . On this elongated arm 22 , the bellows guide 23 is attached, while the air bellows 19 itself is fixed to the vertical support. The air bellows 19 is fixed only with three simple screws, which are not shown here, while the bellows guide 23 is even more simply fixed by a screw with a spring plate, so that assembly and disassembly is made considerably easier.

Fig. 2 further shows that the extended arm 22 extends approximately at an angle of 45 to 50 ° to the base arm of the triangular swing arm 18 .

Securing in the event of a loss of pressure is provided by the sink securing means 24 , which here in the form of an extension whose apex corresponds to the supporting foot on the frame when this is pivoted into a corresponding hole in the locking position or in the dorsal position by appropriately inserting a lock. Such a sink safety device 24 is extremely easy to operate, so that when the pressure drops, the axle rocker 18 cannot change its position beyond this position, but rather is held in this end position, so as to prevent the chassis 7 from further dropping.

With reference to FIG. 3 it is clear that and how the axle rocker described is mounted in the chassis 7 eighteenth The axle bracket 27 , which consists of an axle bolt 28 and the rocker tube 29 in which the axle bolt 28 is accommodated, is used for this purpose. Therefore, this is also referred to as a rocker bearing 30 .

The axle pin 28 , as can be seen in FIG. 3, is equipped on both sides with an angular joint bearing 32 which encompasses the axle pin 28 and ends at the end in a joint attachment 33 , this being true at least for the side 36 of the rocker bearing 30 . The swing arm 29 in turn has a correspondingly adapted to the inclined joint bearing 32 bearing 34 which is held in a bearing 35 to be explained in more detail below.

On the opposite side 37, a simpler version of the Schwin gene bearing 30 'is provided, since here is mentioned on the separate bearing fit mentioned ver. The angular contact bearing 32 rests in the adapted bearing 34 , which in turn is arranged in the rocker tube 29 . The other parts are also simplified, since on this side only a support ring 51 is necessary in order not to interfere with the pushing out of the axle bolt when loosening and pushing through the axle bolt 28 after releasing the anti-rotation device 49 . More on this later. Because of this simplified design of the rocker bearing 30 , this is also referred to as a pivot bearing 50 .

While Figure reproduces. 3 is a zero-position of the Lagerpaßsitzes 35, Fig. 4 shows a position in the modified suspension pivot, ie, with respect wheelbase or track is set. This is indicated by the two dash-dotted lines 38, 38 ' . Here it is also clear that the bearing fit 35 has the shape of a cup-shaped ring 39 , in the bottom part 40 of which a recess 41 for the axle bolt 28 is provided. The cup-shaped ring 39 rests in a ring receptacle 42 which is formed in the rocker tube 29 and is intended to provide a secure and easy to restore tight fit of this ring 39 or the bearing fitting ring 35 .

Referring to Figs. 3 and 4 it is seen that on the thread 45, these can be removed after removing the cotter pin 34 nut from the lock nut 44 and after an appropriate rotation of the fuse 44 and then to move the GESAM th axle bolt to the right side 37th First of all, of course, before actuating the split pin 43 and the locking nut 44 resting in the recess 46 , the screw plate 47 secured by retaining screws 48 must first be removed. Then, as mentioned, the lock nut 44 can be unscrewed.

After the axle bolt 28 has been pushed through, it is now possible to use a puller to remove the entire guide and press sleeve or the joint attachment 33 with the angular joint bearing 32 . The bearing fit 35 with the corresponding shaped bearing 34 can be removed in the same way. On the basis of the previously determined measurement results, the required change in lane or camber can now be determined using a table. For this purpose, the bearing fit 35 or the cup-shaped ring 39 is then changed. There is a complete set, each ring being shaped or labeled 50 so that a corresponding assembly is facilitated. Here, the bearing 34 is offset off-center, so that the track and camber change can be easily recognized when used correctly. In addition, a setting mark 61 is provided for this purpose, which will be referred to later.

Fig. 4 shows in addition to Fig. 3 further that for the protection of the entire Schwin gene bearing 30 a slide-over sealing ring 55 is provided, which is intended to cover the interruption 54 between the oscillating tube extension 53 and the oscillating tube 29 . This interruption 54 is provided in the area of the transition 52 between angled joint bearing 32 and joint attachment 33 . The same is illustrated in FIG. 4.

In the overlap area 56 , a V-shaped ring 57 is arranged, which rubs with its nose 59 against the abutment wall 58 of the sealing ring 55 , so that a seal is still provided even when the track or camber changes as shown in FIG. 4. Fig. 4 illustrates that in the section provided here or shown above the V-ring abuts the shoulder 60 of the sealing ring 55 , while in the lower region the nose 59 just comes up to the abutment wall 58 and here for an effective one Sealing takes care.

Fig. 5 shows a section in the region of the transition between the inclined joint bearing 32 and the joint projection 33 in order to be able to reproduce the fit of the bearing fit 35 somewhat better. For a better overview, the illustration of the axle bolt 28 , the correspondingly shaped bearing 34 and the sealing ring 55 and also the V-ring 57 have been dispensed with.

The ring 39 changing the camber in the swingarm tube 29 can be seen here. Also recognizable is the setting mark 61 , which is intended to facilitate the precise positioning of the pot-shaped ring 39 . Different positions are indicated by the dashed lines, 32 being the angular contact bearing.

All of the above-mentioned features, including those that can only be taken from the drawings, alone and in combination are regarded as essential to the invention.
