    Title Field of the Invention The present invention relates to a maneuvering system according to the preamble of the independent claim. In particular, the invention is directed to a maneuvering system which is adapted to be used in connection with tipping a cab for a vehicle, in particular a truck.
    Background of the invention In connection with, for example, servicing the engine or other systems on trucks, it is often necessary to tip the cab forward in order to access vehicle parts which are located under the cab.
    Today, there are various solutions for maneuvering cab tipping on trucks.
    In essence, it works so that a hydraulic pump creates a hydraulic pressure which via one or more hydraulic cylinders tips the cab resp. return the cab to a normal condition, ie a low vehicle has at normal 'corning.
    The pump can be manually renovated or be an electrically driven hydraulic pump. In order to determine whether the cab is to be tipped or re-fed, a hydraulic directional valve adapted to guide the hydraulic fluid to the intended part of the hydraulic cylinder is usually used, depending on the function to be achieved, which can also be manually or electrically operated.
    The following are a number of patent documents relating to various solutions in connection with cab tipping for vehicles.
    EP0147712 discloses an actuator for a valve used in connection with cab tipping for a vehicle. The actuator is connected to a spring which automatically returns the actuator and valve to a position where the cab cannot be tipped up.
    EP0583039 discloses an adapter for a valve tipping valve. The actuator can with key change from a non-operative to an operative state. The key can only be removed if the valve is in a position where the cab cannot be tilted.
    In cab tipping systems, high demands are placed on both safety and ease of operation. For example, sometimes the cab has to be tipped out on the road and then it is important that this can be done in a safe way and that the driver can carry this out relatively easily.
    With the introduction of electric hydraulic pumps, the complexity of the system increases and so does the requirement to ensure that the intended functionality is achieved.
    The object of the invention is to provide an improved maneuvering system for tipping and returning a cab to a vehicle which meets the requirements for safety and which is easy to handle. A further object is to provide an improved maneuvering system, in particular in connection with the use of electrically driven hydraulic pumps.
    SUMMARY OF THE INVENTION The above objects are achieved by the invention defined by the independent claim.
    Preferred embodiments are defined by the dependent claims.
    Through the actuating system according to the present invention, it is impossible for the directional valve to be left in a position where an undesired pump start can take place, as long as an actuating means is connected to the directional valve.
    According to one embodiment, the maneuvering means for maneuvering the directional valve is designed so that it is only possible to remove the maneuvering means in a release position, for example a bearing where the valve is closed.
    The actuator is preferably designed with a form of "key profile" where insertion and removal is only possible in one position.
    Brief description of the drawing Figure 1 is a schematic view of a vehicle intended to illustrate tipping of the vehicle's cab.
    Figure 2 is a schematic block diagram showing the maneuvering system of the present invention.
    Figure 3 shows a schematic view of the coupling unit according to an embodiment of the present invention.
    Figure 4 shows a cross-sectional view of the connecting sand for the actuator according to the embodiment shown in Figure 3.
    Figure 5 shows a longitudinal cross-sectional view of the interconnecting sand shown in Figure 4.
    Figure 6 shows a schematic front view of a control unit according to an embodiment of the present invention. Figure 7 shows a schematic side view of a control unit according to an embodiment of the present invention.
    Detailed Description of Preferred Embodiments of the Invention The present invention will now be described in detail with reference to the accompanying drawings.
    Figure 1 shows a schematic view of a vehicle 6 with a cab 4. The cab is shown with a solid line in the normal layer and with a dashed line in a tilted layer. The tipping takes place from around a shaft near the front of the vehicle. In the figure, the force which achieves the tilting has been indicated by a bidirectional dashed arrow. How much the cab is tipped depends on the quality of the tipping and the figure should therefore only be considered as a harmless illustration of how the tipping takes place and not, for example, how much the cab is tipped.
    With reference to the block diagram in Figure 2, the invention can now be described in detail.
    The invention relates to a maneuvering system 2 intended to be used in connection with tipping a cab 4 for a vehicle 6. The maneuvering system comprises a hydraulic pump 8 adapted to pump hydraulic fluid to at least one hydraulic cylinder 10 adapted to influence the tipping of the cab 4 for the vehicle 6. The hydraulic cylinder 10 is adapted to affect the cab so that it was forced Than a normal team to a tipped team, and to affect the cab said it was brought back Than the tipped team to the normal team. The operating system is preferably arranged adjacent to the cab, for example on the side of the cab at the entrance.
    The hydraulic pump 8 is connected to the hydraulic cylinder 10 via a directional valve 12. In more detail, the hydraulic cylinder is adapted to pump hydraulic fluid to a directional valve 12 via a hydraulic line 9.
    The directional valve 12 is adapted to be located in at least one first layer 14 in which the low hydraulic fluid is guided so that it controls the hydraulic cylinder 10 so that the cab is conveyed to the tipped layer, and in a second layer 16 in which the low hydraulic fluid is guided so that it controls the hydraulic cylinder. 10 said that the cab is taken to the nominal team.
    In the figure, the first layer 14 and the second layer 16 have been illustrated partly as hydraulic lines 14 and 16 from the directional valve 12 to the hydraulic cylinder 10 and partly as block arrows 14, 16 from the hydraulic cylinder 10 representing the forces exerted by the hydraulic cylinder in the first and second layers, respectively. In more detail, this meant that when the directional valve is in the first layer, the hydraulic fluid is led to the hydraulic cylinder so that the hydraulic cylinder affects the cab so that tipping is drilled and continued. When the directional valve is in the second layer, the hydraulic fluid is led to the hydraulic cylinder so that the hydraulic cylinder affects the cab so that it is returned to the normal position.
    The direction of the directional valve 12 is adapted to be manually installed with an actuator 18 which is adapted to releasably cooperate with the directional valve 12 via a coupling unit 20 fixedly arranged in connection with the directional valve 12.
    The actuator 18 and said coupling unit 20 comprise cooperating couplers such that the actuator 18 can only be detached from the coupling unit 20 when the actuator 18 is in a detachable position. The locking position comprises one or more layers as the directional valve 18 is not in the said first layer 14. That is, it is not possible to remove the actuator Than the coupling unit if the directional valve is in the layer which involved tipping the cab.
    In the release position, the actuator can also be inserted into the coupling unit and in order to then be able to actuate the directional valve in the input position.
    According to one embodiment, the release position comprises one or more layers as the directional valve is not in any of said first 14 or second 16 layers. That is to say, it is not possible to remove the actuator Than the coupling unit onn the directional valve is in the team which involved tipping the cab or in the team returning the cab to the normal team.
    According to one embodiment, the actuating means 18 comprises an interconnecting sand 22 designed to be broken into an opening 24 in said coupling unit 20. This embodiment is shown in Figures 3-5, where Figure 3 shows the coupling unit 20 with the opening 24.
    The coupling end 22 has a profile that allows insertion into, and release from, the coupling unit 20 only when the actuator 18 is in a release position. In the schematic figures 4 and 5 the profile is formed by a pin which is to be held in the upward direction, corresponding to the position designated "0" in figure 3 in order to be able to be inserted and loosened. The profile can of course be designed in many different ways, and have different geometric shapes. The only requirement is that it can be inserted and released in the release position. In the figures, "I" denotes tipping of the cab and "II" refers back to the cab to the normal layer.
    According to one embodiment, the directional valve 12 is thus adapted to be located at least one suspended bearing, for example the position denoted by "0" in the figure. In this layer there is no effect on the hydraulic cylinder 10 with hydraulic fluid, i.e. neither for tipping nor returning the cabin to the normal layer.
    The actuator 18 preferably comprises a maneuvering end 26, on a spirit opposite said interconnecting end 22, intended for manual handling of the actuator 18. See Figure 6.
    The actuator 18 is preferably made of metal, has an elongated shape, for example in the form of a rudder or a solid rod. It has a diameter in the order of 1-2 cm, and has a length, for example in the range 5-25 cm.
    The hydraulic pump 8 can be manually driven and, for example, activated by reciprocating movements on the pump with a pump rod which is attached to the pump on a duty basis.
    According to one embodiment, the hydraulic pump 8 is electrically driven. The electrically driven hydraulic pump 8 is adapted to be controlled by a handheld control unit 28, where the control unit comprises controls 30 for activating and deactivating said pump. The control unit 28 is adapted to control the pump 8 with electrical signals via an electrical cable 32. Figures 6 and 7 show the control unit 28 in a front view and in a side view, respectively.
    Control unit 28 is adapted to be releasably mounted on the vehicle in such a way that it is fixed and held in place by said operating means 18. In Figures 6 and 7 this is done by the control unit being releasably mounted on a support 34 and holding parts 36. In the figures a variant of this, where a stand 34 is arranged under the mounted control unit and holding parts 36 on 6 sides of the control unit and where the parts 36 are provided with openings through which the actuating means can be inserted to hold the control unit.
    With the variant shown, the control unit 28 is mounted and fixed by said operating means 18 in such a way that the operating means 18 is necessary to hold the control unit 28 in the intended place. The purpose of using the actuator to fix the control unit is to prevent the actuator from being forgotten in the coupling unit after the cab has been tipped and then returned to the normal layer.
    The variant shown in Figures 6 and 7 is considered as an example only. Utilizing the actuator to fix the control unit can be accomplished in a number of different ways, for example by letting the holding parts with friction hold the control unit and the actuator so that they can only be reassembled!
    The control unit 28 is, for example, adapted to be mounted under an openable door on the vehicle, for example a door in the front of the vehicle.
    In order to further explain the advantages of the invention, a number of simplified steps can now be described as the driver performs in connection with tipping and return of the cab.
    A. The door is opened where the control unit is arranged.
    B. The maneuvering means is detached and at the same time makes it possible to produce the control unit.
    The actuator is first connected to the coupling unit.
    The actuator is turned to the first layer which relates to tipping the cab.
    E.The electrically controlled hydraulic pump is activated by pressing the intended control on the control unit.
    F.The cabin is tipped.
    Service (exennpelvis) genonnfors.
    The actuator is rotated to the second layer which refers to the return of the cab to the normal layer.
    The cabin is returned to the normal team.
    J.Pump is deactivated.
    The control unit is put back in place and fixed by arranging the actuator so that it secures the control unit.
    The door closes.
    By holding the control unit in place by the actuator, it is ensured that this is not left in the coupling unit.
    According to alternative embodiments regarding the handling of the actuator so as not to lose it, several possibilities can be considered, see example below: The actuator can be a detachable, but with a chain removed, part of the pump rod which just as today has a place under the front cover, the punch pin and the directional valve can sit so close together that a short chain between them can be arranged. This grills a manual pump. or Even on vehicles with electric pump and manual directional valve, a rod is needed which on these vehicles is used for ev. jacks and sleeves for wheel nuts. In this case, the actuator can be directly combined with it. or The actuator can be combined with the towing bolt, which is located on all vehicles and is used for towing, it has a parking position under the lower front cover. or • The actuator can be combined with a glass hammer / bolt cutter mounted in a holder near the driver.
    A further way to prevent the actuator from being forgotten in the coupling unit is to arrange the coupling unit at the entrance to the cab so that if the actuator remains in the coupling unit it is more difficult to enter the vehicle as it then prevents the driver from stepping inside.
    The present invention is not limited to the above-described preferred embodiments. Different alternatives, modifications and equivalents can be used. The above embodiments are, therefore, not to be construed as limiting the scope of the invention as defined by the appended claims.
