    FIELD OF THE INVENTION The invention relates to a wheel suspension for an elongate rail movable in two horizontal planes arranged in parallel in a horizontal plane and to a transport device for the shuttle.
    PRIOR ART Warehouse systems, for example pallet stalls, for heap warehouses and other similar types of warehouses include a large number of beams and rails on which goods, preferably in the form of pallets, can be stored. Usually a number of carriages are arranged and elevators and / or cranes are used to transport goods vertically and laterally. There are also carriages and cranes that move in corridors between pairs of rails. In automated storage systems, there are shuttles, which move autonomously on a pair of rails and can carry and leave goods on the rails. The shuttles roll on a number of wheels and can be transported on cranes, lifts or carriages, on which rails of the same dimensions as in the pallet stable al 'are arranged.
    The shuttles are controlled by control systems and a number of sensors and sensors 'Positions of the shuttles' position and movement. There is always a space between the rails on the pallet stables and the rails on the cranes, lifts and trolleys. The vessels themselves are heavy and can carry loads of several hundred kilos, in some contexts tons. When a shuttle rolls the Over Than rails on a crane to the rails on the pallet rack, the shuttle's wheels will fall into the space between the rails on the crane and the pallet rack and partially hit a leading edge of the rails. There may be bumps in the bearing system and wear on the rails and on the wheels of the shuttle.
    SUMMARY OF THE INVENTION An object of the invention is therefore to provide a wheel suspension flap which obviates the above-mentioned problems and disadvantages. In accordance nned AH p4499se00 ps sv.docx 13-12-10 ver. In the invention the load on the rails is reduced, in particular where the shuttles move by crane or carriage over to the rails in the pallet stable. A wheel suspension in accordance with the invention is arranged in each horn of a substantially rectangular vessel. Each such wheel suspension includes a bogie which carries two rotatable shuttle wheels in the direction of movement of the shuttle. The shuttle wheels rotate in a vertical plane when the shuttle moves forward and backward on the rails. The bogie is rotatable about a first axis arranged between the shuttle wheels and lies essentially in a horizontal plane at rest and during normal movement. A underside of the bogie is challenged like a jug surface, which extends in front of, behind and below the shuttle wheels.
    On each crane and trolley that transports the shuttle, cam rollers are arranged close to the rails which are on the crane and on the trolley, respectively. The cam rollers are arranged at such a height that the cam surface of a passing bogie will abut against them. A shuttle that is to leave the crane or trolley moves towards the rails entering the pallet stable. In connection with the shuttle's shuttle wheel leaving the rails on the crane or trolley and passing nnellanrunnnnet nnellan the rails on the crane or trolley and the rails on the pallet stable, a cam surface comes into contact with a cam roller. The entire bogie will then rotate around the first axle and lift up the shuttle wheel that leaves the rails on the crane or trolley.
    As the shuttle continues to move, a recessed portion of the cam surface will pass the cam roll, which means that the bogie will be rotated back to the original position in the horizontal plane. At the same time, the shuttle wheel that has left the crane or trolley will be lowered against the rails of the pallet stable, without hitting the ends of the rails.
    BRIEF DESCRIPTION OF THE DRAWINGS In order to explain the function and advantages of the invention, various embodiments of the invention are shown in the accompanying figures. It should be noted that the designs AH p4499se00 ps sv.docx 13-12-10 ver. 3 of the figures are only examples and that other embodiments are possible within the scope of the invention.

THE INVENTION The embodiment of a wheel suspension 10 in accordance with the invention is shown when a second part of the bogie is lifted when abutting against a cam roller. The rails 12 are arranged on a shuttle 14, which moves on rails 12. The rails 12 shown on the left in Fig. 1 belong to a pallet stable and the rails 12 'shown on the right belong to a crane (not shown). The wheel suspension 10 is arranged pivotable about a first axis 20 on a side piece 22 of a shuttle 14. The wheel suspension supported two shuttle wheels 16 on a bogie 18. The bogie 18 is on the underside challenged by a cam surface 24.
    The shuttle rests with its shuttle wheels 16 on the rails 16, 16 '. In the position shown in Fig. 1, a first shuttle wheel 16 (to the left in the figure) has passed a space 17 between the rails on the pallet stable and the rails on the crane. The gap 17 has a length D, which can be up to 30 mm or more. In the AH p4499se00 ps sv.docx 13-12-10 ver. The embodiment shown in Fig. 4 is that the shuttle wheels 16 of the bogie 18 are arranged at the same height in a vertical plane. The cam surface 24 extends below the shuttle wheels 16.
    Near the spirits of the rails 12 ', the crane carries a fixedly arranged cam roller 26. In the layer shown in Fig. 1, the cam surface 24 has come into abutment against the cam roller 26. As a result, the part of the bogie 18 left in Fig. 1 has been raised by the bogie 18 has pivoted about the first axis 20. This means that a shuttle wheel 16 (to the left in Fig. 1) has been lifted over a horizontal portion 28 of the rail 12 and has not hit the spirit of the rail 12. The shuttle wheels 16 rotate about horizontally arranged second axes 30.
    In the position shown in Fig. 2, the shuttle wheel 16 to the right of the bow 18 has also passed the gap 17. Such the shuttle wheels 16 now rest on the horizontal portion 28 of the rail 12 on the pallet stable and the bogie 18 has a completely horizontal bearing. A rear set of shuttle wheels on a rear bogie (not shown) will in the same way pass the gap 17, without any shuttle wheel 16 falling into the gap 17 between the rails 12, 12 '.
    Fig. 3 shows an embodiment of a rectangular challenge vessel 14 with a bogie 18 in each horn. The shuttle wheels 16 are challenged as rubber wheels and are rotatably arranged around the other shafts 30 in a side piece 22 of the respective bogie 18. The entire bogie 18 is rotatable about the first shaft 20. Fig. 3 also shows that each bogie 18 is provided with a transverse frame. guide wheel 32, which rotates about a vertical axis of rotation. The guide wheels 32 abut against a vertical portion of the rails 12, 12 '.
    Fig. 4 schematically shows how a shuttle 14 with the help of the jug roll 26 is "lifted" over the space 17 between the rails 12 'on a crane 34 and the rails 12 in a pallet stable 35. This takes place when the shuttle 14 moves to the left in Figs. 4 and the bogie 18 with its cam surface is forced upwards when passing the cam roller 26.
    In the embodiment of a bogie 18 shown in Fig. 5, the cam surface 24 is challenged with sunken portions 36 below the respective shuttle wheel 16 and an intermediate raised portion 38. When the raised portion 38 passes a cam roller 26, the shuttle wheels 16 rest on rails. 12, 12 '. When a sunken portion 36 passes the cam roller 26 (dotted line position), the corresponding part of the bogie AH p4499se00 ps sv.docx 13-12-10 ver. 18 to be swung upwards, as indicated by the arrow A, since the lowered portion 36 comes into abutment against the cam roller 26. The shuttle wheel placed at the lowered portion 36 will thereby be lifted to a position above the rail 12, 12 ', while opposing shuttle wheels will remain and roll against a rail 12, 12 '. The jug roller 26 is fixedly mounted in the crane and is suitably rotatably arranged about a third axis 40. The cam roller may be challenged with rubber coating or the like to vaporize the movement when the cam curve of the bogies 18 is pressed to abut against it. The guide wheel 32 rests against an inside of the rail 12, 12 'during the movement of the shuttle.
    In the embodiment of the bogie 18 shown in Fig. 6, a first inclined portion 42 of the cam surface 24 is connected to abutment against the cam roller 26 when the shuttle 14 moves in the direction of the arrow B. The shuttle wheel 16 closest to the inclined portion 42 is then lifted in the direction of the arrow C and will lie above the rail 12 of a pallet stable 35, when the shuttle wheel 16 has passed the space 17. The entire bogie 18 is rotated about the first shaft 20, while the entire bogie 18 lifts something up.
    In Fig. 7, the shuttle 14 with the bogie 18 in Fig. 6 has moved further in the direction of the arrow B. The shuttle wheel 16 which was raised in Fig. 6 now rests against the rail 12 of the pallet stable 35. At the passage of the raised portion 38 past the cam roller 26, both shuttle wheels 16 have rested against the respective rail 12, 12 '. In the layer shown in Fig. 7, a second inclined portion 44 has the nail roller, which will lift the shuttle wheel 16 lying closest to the second inclined portion 44. The entire bogie 18 will also be rotated about the first axis 20. At the shuttle 14 further movement To the left in Fig. 7, the shuttle wheel 16 lying closest to the second inclined portion 44 will pass the gap 17 in a slightly raised layer and then be lowered towards the rail 12 of the pallet stable, when the entire cam surface has passed the cam roller 26.
