    The invention relates to a loading system for a loading vehicle with telescopic loading system, with at least one telescopic boom equipped with telescopic drive, the rear, vehicle-side boom end is pivotally connected to a frame and the free end of the boom can be coupled with a loading tool, wherein the boom in addition to a rotary actuator is displaceable between a lower and an upper working position.
    Loading vehicles, especially telescopic loaders, generally have a tool holder that can be equipped with different attachment tools to perform a variety of jobs. The tool holder on a telescopic loader is usually arranged at the free end of the boom and can be pivoted about a free end of the boom mounted kinematics about an axis extending transversely to the longitudinal axis of the telescopic loader, whereby, inter alia, an approximate parallel guidance of a tool between lower and upper working position can be guaranteed , Such loading vehicles lift a tool along an arc around the vehicle-side articulation point of the boom, wherein the tool is displaced away within a Hubbereiches forward of Ladefahr- convincing and moved back to the loader vehicle after exceeding the maximum distance to the loader vehicle. This arcuate motion can be superimposed on a linear motion by corresponding telescoping of the cantilever.
    In operation, telehandlers should be able to lift, lower and relocate heavy loads in short periods of time. At the same time, high demands are placed on the driver with regard to the simultaneity of the control of the individual drives, which, in the event of incorrect operation of the machine, poses hazardous situations, in particular 16/03/2011 15:12

    Tipping the loader, can cause. For this reason, telehandlers are equipped with an automatic overload protection, as known for example from DE 10 2009 018072 A1. In the solutions presented so far, for example, the hydraulic connection between the pump and hazardous consumers is switched off in case of overload. So that the vehicle remains stable due to the then acting braking acceleration and in particular does not tip over, the lowering speed of the work equipment is generally or depending on suitable sensor signals reduced, but with this the duration of the working cycles is increased.
    Based on a state of the art of the type described, the invention has the object, a charging system, a method for driving a mobile machine and a mobile machine, in particular a telescopic loader to create, raised with the high loads in shortened periods, lowered and can be offset. According to an advantageous embodiment, a movement which is as fast as possible along a vertical over at least one stroke range should also be possible over shorter periods of time.
    The invention achieves this object by the fact that the boom length in connection with the boom pivoting position is limited by a control associated with the telescopic drive and the pivot drive to a region which does not project beyond a virtual, vertical plane perpendicular to the boom pivot axis in the region of the free boom end, wherein the normal distance of the plane to the boom pivot axis is smaller than the largest boom length
    It is essential that with the system according to the invention areas which can result in a tilting of the vehicle can be recessed automatically from the outset. In principle, all the movements are possible in which the telescopic drive and the rotary actuator accomplish a lifting and lowering movement of the working equipment via a control input, which does not cause an unauthorized increase in the load torque, in particular about the vehicle front axle as a tilting axis. By this measure, high loads can be shortened in 16/03/2011 15:12

    Periods are raised, lowered and offset. Lifting and lowering operations of the work equipment are carried out with the invention within the corresponding characteristics, wherein in particular the normal distance of the allowable lifting range limiting plane to the boom pivot axis of the control load-dependent and taking into account appropriate collateral can be specified or calculated. The functions according to the invention can only be provided for lowering or lifting functions or for lowering and lifting functions. A manual overlay of the lifting function with the telescoping function of the controller can remain possible. When lifting vertically, the Austeleskopierfunktion can be switched off when it comes to a load magnifying moment in the longitudinal direction of the machine which would cause a risk situation in size. When lowering, the movement can also be allowed by overlaying the Austeleskopierfunktion. As soon as the stability of the machine is in the limit range, only the lowering movement in the vertical movement according to the invention can take place automatically. A telescoping with the function is in any case not critical and can be allowed in any case.
    If the length of the boom is set as a function of the boom pivot position by a control associated with the telescopic drive and the pivot drive in the sense of an at least partial shutdown or achieving an at least partially constant distance of the free arm end to the plane, an approximate vertical stroke can be ensured in a simple manner. In this context, vertical stroke is understood to mean that a load or a tool is displaced along or behind a vertical which is related to the vehicle coordinate system and is displaced synchronously with the vehicle, in particular during the movement of the vehicle. Thus, a load along a straight line can be displaced as well as from a circular or arcuate path, which does not leave the permitted range, within the permitted range telescopic drive and the rotary actuator for the realization of Vertikalhues invention can be automatically controlled by only one control specification. 16/03/2011 15:13

The load is preferably lowered vertically or partially vertically, for which purpose the telescopic cylinder of the boom is retracted parallel to its lowering movement. The same applies to a lifting of loads. In a vertical displacement does not increase the load torque and the machine can not tilt, which is why the Überiastabschaltung can be made relatively simple. The duration of the work cycles can sometimes be increased compared to prior art machines.
    The invention can be realized in various ways. Preferably, a hydraulic or electro-hydraulic telescopic drive and rotary actuator will be provided for the charging system. Alternatively or in combination, it is also possible to provide an electric Teieskopantrieb and rotary actuator or to mechanically couple the telescopic drive and the rotary actuator. The Vertikalhubfunktion can be made switchable, so if necessary, the machine optionally realize free working cycles in the context of the prior art or can perform lifting and lowering movements in Vertikalhub.
    Particularly safe conditions result from a hydraulic coupling when the telescopic drive and the rotary actuator are connected in series and when the displaced in the telescopic drive or rotary actuator flow drives the rotary actuator or telescopic drive.
    In such a hydraulic or electro-hydraulic interconnection, an oil volume flow, for example, initially supplied to the rotary actuator for lifting / lowering the boom. The displaced in the rotary actuator or displaced oil flow, for example, on the opposite side of the piston of a hydraulic cylinder displaced Voiumenstrom is thereby fed to the telescopic drive. Which in turn displaced in the telescopic drive 16/03/2011 15:14

    Volume flow is preferably discharged to the tank. The area ratios of the hydraulic actuators must be matched to the desired Vertikalhubbewegung for these simple conditions. In addition, one or the other volume flow, however, can still be supplied or withdrawn from hydraulic fluid, for example also as a function of the respective pivoting angle of the arm.
    For pre-controlled systems or electrohydraulic systems, logic functions can be routed into the controller to achieve load independent lift ratios. In order to increase the accuracy of the vertical stroke or to achieve an exact vertical movement of the tool, system variables such as lengths, angles of rotation, forces, accelerations u. Like. Be returned from the system in the controller. The control can also be supplemented by a control, in the control is further provided that the lifting or lowering movement is continued unimpaired when fully extended or retracted telescopic cylinder. Furthermore, corresponding elements can be added to realize safety-related Abschaitpfade the system. These statements apply to all embodiments of the invention.
    Alternatively, the swivel drive can be assigned a compensation drive connected in parallel with the swivel drive, which is connected in series with the telescopic drive, wherein the volume flow displaced in the compensation drive or telescope drive drives the telescopic drive or compensating drive.
    In this variant, an automatic positive coupling between rotary actuator and telescopic drive is realized by a compensation drive, preferably in conjunction with a logic element. The compensation drive is for this purpose, for example, connected to the mast and thus directly mechanically coupled to the pivot drive for lifting / lowering. Upon initiation of a lifting or lowering movement, oil quantity is shifted in the compensating drive. This is fed to the telescopic drive. Using selected area ratios, the telescopic movement for the lowering / lifting movement can be adjusted such that the point of articulation for the 16/03/2011 15:14

    Tool, or the tool itself, at least almost in Veitikalhub is moved. The logic element may include required safety functions as well as allowing normal pivotal movement when a drive is in its end position. For this purpose, it is possible to conduct additional volume flows via the logic element. It is also possible to supply a volume flow to compensate for shortages which arise as a result of superimposed telescoping movements.
    The compensating drive may exceed a dead center when the boom is displaced between the lower and the upper working positions in order to achieve a movement path of the free arm end extending at least almost along a vertical. With such an arrangement, the vertical stroke can also be realized in the lower stroke range of the device by reversing the conveying direction in the compensation drive when passing through the dead center position.
    In a further advantageous embodiment of the invention, the telescopic drive and the pivot drive are connected in parallel, wherein in at least one supply line to the drives a flow divider is provided.
    In this variant, the forced coupling between the telescopic drive and rotary actuator is realized on actuation of the lifting / lowering function on the control by a quantity sharing of the flow flowing to the telescopic drive and rotary actuator flow. The amount of division is independent of the load in an adjustable ratio. This telescopic drive and rotary actuator are supplied in parallel and the desired movement is implemented. If a drive is moved to an end position, the circuit ensures that the other drive can continue to be moved without restriction. For example, so always lowering movements are possible even with full Einteleskopierung the boom. The logic allows oversteer of the telescopic movement on the vertical stroke movement in a particularly simple manner, but only insofar as no unauthorized high tipping moment can be effective. 16/03/2011 15:15

    Likewise, a flow divider may be provided in at least one supply line between telescopic drive and rotary drive, the excess fluid preferably returns to a tank.
    In this variant, the forced coupling between the telescopic drive and the rotary actuator when the lift / lower function is operated on the control is achieved by a serial circuit, but this extends the functionality of the pure serial interconnection. The volume flow coming from the control part upon actuation of the lifting function is first directed to the telescopic drive, for example. The flowing back from the other displacement of the telescopic drive volume flow is fed to a flow divider. An adjustable amount of the volume flow now reaches the rotary actuator, whereby the desired lifting function can be realized. Excess amount is returned to the tank.

The control of the telescopic drive 2 and pivot drive 7 via a controller 8, wherein the required energy is provided by a supply unit 9 and a switching logic 10.
    In order to raise or lower loads as quickly as possible without having to fear tipping of the telescopic loader 1, the boom length L is dependent on the boom pivot position, in particular from the boom pivot angle a, of a control 8 associated with the telescopic drive 2 and the pivot drive 7 on one Area B limited that a virtual, vertical and perpendicular to the boom pivot axis 11 standing plane E in the region of the free boom end 12 does not exceed, the normal distance N of the plane E to boom pivot axis 11 smaller than the largest boom length Lg but larger than the smallest boom length Lk is. With such a device or with such a charging system, basically all movements in an allowed area B are possible, which cause no unauthorized increase in the load torque, in particular about the vehicle front axle, which increase the load torque possibly even a tilting of the vehicle over the vehicle front axle result could. However, an overlay can still be allowed, for example, after deliberate circumvention of a security circuit
    If the boom length L is specified as a function of the boom pivot position by the control 8 associated with the telescopic drive 2 and the pivot drive 7 in the sense of at least partially stopping or achieving an at least partially constant distance of the free boom end 12 to the plane E, a vertical displacement of a load can be achieved be made. Thus, in the ideal case, until the maximum boom length Lg has been reached, a vertical movement of the load in or parallel to the plane E can be realized. In the following, the invention is presented by means of block diagrams or circuit diagrams for a hydraulic or an electro-hydraulic telescopic drive 2 and pivot drive 7. 16/03/2011 15:16

    In the most general case (FIG. 2), the supply of telescopic drive 2 and rotary drive 7 takes place with energy via a switching logic 10 from the supply unit 9, an energy store, a pump or the like. The control gives the Schait logic 10 at how much energy the respective drive is to supply to map the desired lifting function on the load. In order to be able to take into account feedback from system variables, a feedback of system variables to the controller 8 is indicated. According to a particularly advantageous embodiment of the invention, a control is thus optionally provided. The supply unit 9 can also record a circuit part or parts of the controller.
    According to FIG. 3, telescopic drive 2 and rotary drive 7 are connected in series, with the volume flow displaced in telescopic drive 2 or in rotary actuator 7 driving rotary actuator 7 or telescopic drive 2. For example, the swivel drive is actuated for lifting and the hydraulic fluid flow displaced in the swivel drive on the opposite side is forwarded via the switching logic 10 to the telescopic drive 2. The displaced in the telescopic drive 2 liquid is returned, for example, to the supply unit, the control guide member 9 and optionally in the tank.
    In the block diagram according to FIG. 4, the pivot drive 7 is assigned a compensation drive 13 connected in parallel to the pivot drive 7, which is connected in series with the telescopic drive 2 via the control logic 10, wherein the volume flow displaced in the compensation drive 13 or telescopic drive 2 is the telescopic drive 2 or the compensation drive 13 drives, depending on whether the boom should be raised or lowered.
    In the embodiment of FIG. 5 is a block diagram with serial interconnection of rotary actuator 7 and telescopic drive 2 is shown with serial connection, wherein in the connecting line between telescopic drive 2 and pivot drive 7, a flow divider 14 is provided, the excess fluid in a tank, the 16/03 / 2011 15:17

According to Fig. 6, for example, a parallel connection with additional flow divider 14 is provided.
    The following circuit diagrams show highly simplified hydraulic circuits that are suitable for realizing the invention. The switching logic is again denoted by 10 and includes various, optionally controlled by the controller 8 switching or control valves.
    Fig. 7 shows a direct coupling, namely a series connection between the telescopic drive 2 and pivot drive 7, wherein each displaced on an opposite piston surface amount of hydraulic fluid from a cylinder is used to control the other cylinder. With the provision of a corresponding valve technology between telescopic drive 2 and pivot drive 7 or in their environment, the desired Vertikalhubfunktion can be adjusted and used. As a result of different drive lengths, it can occur naturally that a simultaneous movement of the cylinder, in particular in the region of the end positions, is no longer possible. For these cases, corresponding limit switches are provided which, for example, open or close bypass channels.
    A simplified circuit for a vertical lowering movement with serial connection and with additional flow divider 14 is shown in Fig. 8. Upon actuation of a lifting cylinder valve, the volume flow from the supply device 9 of a pump, passed through valves 10 to the telescopic drive 2 and displaced on the bottom side of the telescopic cylinder oil is passed through the flow divider 14 to the pivot cylinder. Excess amount is returned from the flow divider into a tank. In order to allow even after a complete exodus / retraction / retraction of the telescopic drive 2 against the stop and an adjustment of the rotary actuator 7, again a bypass line is provided. A parallel connection of the telescopic drive 2 and pivot drive 7, for example, Fig. 9. 16/03/2011 15:17

    A circuit variant with compensation drive 13 is shown for example in FIG. 10. The operation is similar to the variant according to FIG. 7. The defined division ratio between the movement speeds of telescopic drive 2 and pivot drive 7 is determined via the compensation drive 13. Thus, the displaced during a pivoting movement of the boom in the compensation drive 13 amount of fluid can be used directly for the telescoping of the boom. Scribing circuits and functionally important valves complemented the structure again. ^ 16/03/2011 15:18
