    Self-propelled agricultural harvester with two internal combustion engines
    The invention relates to a self-propelled agricultural harvesting machine, comprising: functional components for receiving and / or processing crops; operational components for propulsion and steering of the harvester; a first internal combustion engine; a second internal combustion engine; a first mechanical driveline connecting the first internal combustion engine to the functional components and a second mechanical driveline connecting the second internal combustion engine to the operational components.
    State of the art
    Self-propelled agricultural harvesters have recently been equipped with increasingly powerful internal combustion engines, which can currently deliver more than 800 kW for forage harvesters. Because of the relatively small quantities in which such powerful engines are made, these engines are relatively expensive and usually more expensive than two internal combustion engines, each with half the power. Furthermore, the entire power of the engine is not always needed, because it is not required for example when transporting on a road or at the grass harvest, resulting in a poorer efficiency of the engine than in full load operation. It has therefore been proposed to equip a self-propelled harvester with two internal combustion engines, one of which is connectable to the other internal combustion engine to cope with larger power requirements:
    According to EP 1 640 201 A1, the crankshafts of the two internal combustion engines are oriented transversely to the forward direction and horizontally, with one internal combustion engine positioned in the forward direction in front of the other internal combustion engine. A spur gear establishes a connection between the crankshafts of both internal combustion engines and the main driveline of the harvester. Between one of the internal combustion engines and the spur gear a disconnectable clutch is arranged to drive the harvester even with a single internal combustion engine, without having to run the other engine.
    Another forage harvester with two combustion engines is described in EP 1 813 459 A1. The internal combustion engines are arranged transversely to the forward direction and behind one another. A belt transmission connects the crankshaft of the rear internal combustion engine with the crankshaft of the front internal combustion engine, which in turn drives a drive belt, which is in drive connection with the largest power consumers (chopper drum and fan).
    DE 10 2007 019 661 A1 describes an agricultural forage harvester with two laterally juxtaposed, extending in the direction of travel internal combustion engines whose crankshafts are connected via propeller shafts and a spur gear with an angle gear which drives a pulley via a transverse shaft, via a main drive belt drives the chopper drum.
    Similarly, DE 10 2009 047 343 A1 describes a forage harvester with two internal combustion engines whose crankshafts are coupled via clutches with angular gears. The angle gear are connected to each other via a propeller shaft and drive a pump unit for the drive and a third clutch to the chopper drum and the fan. DE 10 2009 028 094 A1 describes a similarly constructed forage harvester, in which the motors drive the chopper drum and a pump unit for the traction drive via the clutches and belt drives.
    In the class considered as CN 2 616 024 Y a combine harvester with two internal combustion engines is described, in which an internal combustion engine, the operational components (propulsion and hydraulics) and the second internal combustion engine, the functional components (Erntegutförder- and threshing) drives. The second combustion engine is needed only in the field and is therefore turned off when driving on the road.
    Furthermore, EP 2 250 873 A1 describes a combine harvester with two internal combustion engines, gearboxes which are associated with them drive mechanical loads and generators which in turn drive electrical loads (drive motors). Here, a power transmission from a motor to any components, but via the lossy detour electrical power transmission. EP 2 253 192 A1 describes a similar combine harvester in which the internal combustion engines are connected to a single transmission which drives mechanical loads and a generator and allows individual coupling of the loads.
    In the aforementioned forage harvesters (EP 1 640 201 A1, EP 1 813 459 A1, DE 10 2007 019 661 A1, DE 10 2009 028 094 A1 and DE 10 2009 047 343 A1), three modes of operation are provided: an operating mode in which only a single internal combustion engine is running, driving both the functional components (crop conveying and processing equipment) and the operational components (propulsion, steering, on-board hydraulics, electrical and possibly air conditioning); an operating mode in which both internal combustion engines are mechanically coupled together and drive the functional and operational components; and a mode in which the functional components are turned off by a clutch during road travel. However, there is no mode of operation in which (as in CN 2 616 024 Y) an internal combustion engine drives the functional components via a mechanical drive train and another internal combustion engine drives the operational components via a mechanical drive train. This latter mode of operation has the advantage that the operational components can be driven at constant speed, regardless of the load on the harvester. This operating mode is also not possible with the combine harvesters provided with electric power transmission according to EP 2 250 873 A1 and EP 2 253 192 A1.
    Object of the invention
    The object underlying the invention is seen to provide a drive arrangement for a self-propelled harvester with multiple internal combustion engines, which can be operated in a mode in which an internal combustion engine via a mechanical drive train, the functional components and an internal combustion engine via a mechanical drive train operational Components drives, and in another mode, the two internal combustion engines are mechanically coupled together.
    This object is achieved by the teaching of claim 1, wherein in the other claims features are listed, which further develop the solution in an advantageous manner. Solution of the task
    A self-propelled agricultural harvester includes functional components for receiving and / or processing crop, operational components for propulsion and steering of the harvester, a first internal combustion engine, a second internal combustion engine, a first mechanical driveline connecting the first internal combustion engine to the functional components, and a second mechanical drive train connecting the second internal combustion engine with the operational components. A first clutch makes it possible to couple the first drive train optionally with the second drive train.
    In this way, the harvester can be selectively operated with the first clutch open in a first mode in which the first drive train is disconnected from the second drive train and the first internal combustion engine via the first drive train drives the functional components of the harvester, while the second internal combustion engine via the second Powertrain drives the operational components of the harvester. When the first clutch is closed, the two drive trains in the second mode, however, are coupled together. The first mode of operation enables independent operation of both internal combustion engines so that the second internal combustion engine and the functional components can be driven at a speed independent of crop throughput. In the second mode of operation, power may also be provided by the second internal combustion engine to drive the functional components. For manual or automatic selection of the respective operating mode, the first clutch is provided with a power-operated actuator, which is connected to a controller, which is set up, automatically or on an operator input between a first operating mode in which the first clutch is disconnected and a second Mode in which the first clutch is closed, to switch.
    Preferably, a second clutch is inserted between the second internal combustion engine and the second drive train. It allows a (third) mode of operation in which the first internal combustion engine drives both the functional and operational components of the harvester and the second internal combustion engine is stationary. This mode may be useful at relatively low Erntegutdurchsätzen.
    The first crankshaft and / or the operational components may be connected to the first clutch via a spur gear transmission. The first driveline may include a crankshaft coaxial shaft coupled to a crankshaft of the first engine, an angular gear input coupled to the shaft, a pulley coupled to the output side of the angular gear, and a belt.
    A third, inserted in the first drive train clutch makes it possible to turn off the functional components, which may be useful, for example, when turning in the headland or when moving the harvester in a field, since the first engine then usually continues running, but put the functional components out of action become. In a road trip, however, the first internal combustion engine is usually turned off, while the operational components are driven by the second internal combustion engine.
    The controller is in particular configured to select the second operating mode when the power requirements of the functional components exceed a threshold value which corresponds to a maximum power of the first internal combustion engine.
    Ausführungsbeisoiel
    With reference to the figures, three embodiments of the invention will be explained. Show it:
    1 is a schematic side view of a self-propelled harvester in the form of a forage harvester,
    2 is a schematic plan view of a first embodiment of the drive arrangement of the harvesting machine,
    Fig. 3 is a schematic plan view of a second embodiment of the drive assembly of the harvester, and
    Fig. 4 is a schematic plan view of a third embodiment of the drive assembly of the harvester.
    1 shows a harvester 10 in the manner of a self-propelled forage harvester is shown in a schematic side view. The harvester 10 is built on a frame 12 supported by front driven wheels 14 and steerable rear wheels 16. The operation of the harvesting machine 10 is carried out by a driver's cab 18, from which a header 20 in the form of a pickup is visible. By means of the header 20 picked up from the ground crop, z. As grass or the like is fed via a feed conveyor 22 with Vorpresswalzen, which are arranged within a feed housing 24 on the front side of the forage harvester 10, arranged below the driver's cab 18 chopper drum 26, which chops it into small pieces and gives it a conveyor 28. The crop leaves the harvesting machine 10 to a transporting vehicle traveling alongside by means of a discharge shaft 30 which can be rotated about an approximately vertical axis and tilted in the inclination. In the following, directional details, such as laterally, downwardly and upwardly, refer to the forward movement direction V of the harvesting machine 10, which in FIG the figure 1 runs to the right.
    FIG. 2 shows a top view of a first embodiment of a drive arrangement of the harvesting machine 10. In the rear area of the harvesting machine 10, there are two (first and second) internal combustion engines 36, 38 arranged in the rear of the rear axle, in particular in the form of diesel engines, arranged side by side and with Side members and / or cross members of the frame 12 are connected and each supported separately on the frame 12, or mounted on an auxiliary frame, which in turn is attached to the frame 12. Between the internal combustion engines 36, 38 and the frame 12 and the subframe each vibration-damping rubber-metal elements may be arranged. The powers of the internal combustion engines 36, 38 are preferably identical, although internal combustion engines 36, 38 of different power would be usable. The internal combustion engines 36, 38 extend in the forward direction of the harvester 10 to about the rearward end of the frame 12 and include (first and second) crankshafts 40, 42 extending forwardly out of the housings of the internal combustion engines 36, 38. The crankshafts 40, 42 each drive a horizontally and forwardly extending (first and second) longitudinal shaft 44, 46 at.
    The first longitudinal shaft 44 is connected at its front end to a bevel gear 52 which is composed of a first bevel gear 48, which is directly connected to the first longitudinal shaft 44, and a second bevel gear 50, which meshes with the first bevel gear 48. The axis of rotation of the second bevel gear 50 extends horizontally and transversely to the forward direction. The second bevel gear 50 is connected to a portion 54 of a first transverse shaft 54, 80, which in turn is connected to a (third) clutch 78, which is the output side coupled to a second portion 80 of the transverse shaft 54, 80.
    The second longitudinal shaft 46 is connected at its front end to a (second) clutch 60, which is the output side coupled to a third longitudinal shaft 62 which extends coaxially with the longitudinal shaft 46. The longitudinal shaft 62 is connected at its front end to a (first) coupling 64, which in turn is connected via a fourth longitudinal shaft 66 with a gear 68. The gear 68 is engaged with a second gear 70, which in turn meshes with a third gear 72 which is rotatably mounted on the first longitudinal shaft 44. The third longitudinal shaft 62 carries between the third clutch 60 and the first clutch 64 is still a circumferentially toothed gear 74, which meshes with another gear 76 which drives a fifth propeller shaft 92 via a fifth power unit 92, which is a hydraulic pump for hydraulic supply of hydraulic motors 94 for the propulsion of the harvester 10 and a steering pump for the hydraulic supply of a hydraulic steering drive 96 for steering the rear wheels 16 includes.
    The second portion 80 of the transverse shaft 54, 80 is connected at its spaced from the third clutch 78 end pulley 82. The pulley 82 is wrapped by a drive belt 84, which also wraps around a pulley 86 for driving the conveyor 28 and a pulley 88 for driving the chopper drum 26. Instead of or in addition to the third clutch 78, the drive train of the cutterhead 26 and the conveyor 28 may be set in motion or stopped by a mechanism for tensioning and releasing the drive belt 84. The drive of the header 22 via a hydraulic motor 104 which is hydraulically powered by a pump 102 which is driven by gears 98,100 from the second portion 80 of the transverse shaft 54, 80.
    A controller 106 is connected to an operator interface 108 and actuators 110, 112, 114 that serve to drive the first clutch 64, the second clutch 60, and the third clutch 78.
    In the embodiment of Figure 1, the first transverse shaft 44, the angle gear 52, the cross shaft 54, 80, the pulleys 82, 86, 88 and the belt 84 and the gears 98 and 100 form a first, mechanical drive train, which is used to drive the functional Components of the harvester 10 is used, namely the conveyor 28, the cutterhead 26 and the pump 102 for the hydraulic drive of the header 22 is used.
    Analogously, the second and third transverse shafts 46, 62, the gears 74, 76 and the fifth transverse shaft 90 form a second, mechanical drive train which serves to drive the operational components of the harvester 10, namely the pump unit 92 for the hydraulic supply of the steering drive 96 and the Further, driven by the second drive train operational components cooling fan (not shown) for the
    Internal combustion engines 36, 38 and be an air conditioner.
    The first clutch 64 is interposed between the first driveline and the second driveline and allows it to be interconnected (via the gears 68-72 and the fourth prop shaft 66). The second clutch 60 enables an operation mode in which the second internal combustion engine 38 is turned off. The third clutch 78 serves to switch off the functional components of the harvester 10.
    The operator in the cab 18 can thus select via the operator interface 108 a first mode in which the first clutch 64 is disconnected. Then, the first internal combustion engine 36 drives the functional components of the harvester 10 via the first drivetrain, which are supplied via the third clutch 78 as needed, e.g. in the headland or when moving in a field, can be switched off, while the second internal combustion engine 38 drives the operational components of the harvester 10 via the second drive train. This mode of operation allows the second internal combustion engine 38 to operate independently of the speed of the first internal combustion engine 36, which in turn depends on the crop throughput, which simplifies the control of the operational components. This is especially true in the case that the nominal power of the two internal combustion engines 36, 38 differs.
    In a road trip, the first internal combustion engine 36 is turned off by the controller 106 and only the second internal combustion engine 38 drives the operational components via the second driveline. Roadside detection may be accomplished by a corresponding input to the operator interface 108, e.g. may include a road / field switch, or automatically by the controller 16 based on the mode of operation of components of the harvester 10, see. the disclosure of EP 1 405 555 A1.
    Should the power requirements of the first powertrain exceed the maximum output of the first internal combustion engine 36, the operator via the operator interface 108 and the controller 106 may cause the actuator 110 to close the first clutch 64 and the second internal combustion engine 38 to also power the second engine first powertrain delivers. This control process can also be carried out automatically, based on a detection of the power of the first internal combustion engine 36 by means of a motor controller 116 assigned to it.
    The second clutch 60 and the associated actuator 112 make it possible to separate the second internal combustion engine 38 from the second drive train and to allow the entire drive power to be provided by the first internal combustion engine 36 when the first clutch 64 is closed. The controller 106 then causes an engine controller 118 of the second internal combustion engine 38 to stop it. This operating mode makes sense with relatively small Erntegutdurchsätzen, which can be detected by the controller 106 based on the detected by the engine control 116 load of the first internal combustion engine 36 and used to select this mode.
    The second embodiment of Figure 3 differs from the first embodiment only in that the first clutch 64 has now been inserted between the gear 70 and another, coaxial gear 71, which in turn meshes with the gear 68. The first clutch 64 is thus connected by transverse shafts 65, 66 with the gears 70, 71. The operation of the drive assembly of Figure 3 is identical to that of the drive assembly of Figure 2.
    FIG. 4 shows a third embodiment of a drive arrangement according to the invention. Elements that match the first and second embodiments are identified by the same reference numerals. In the third embodiment, the first drive train is composed of the first longitudinal shaft 44, a fourth clutch 120, a sixth longitudinal shaft 122, the angle gear 52 with the bevel gears 48, 50, the portion 80 of the transverse shaft, but through a hollow shaft 124, which is connected to and extends through the pulley 82, which is arranged on the outside of the pulley 82, the third clutch 78, the hollow shaft 124 which the output side of the third clutch 78 with the pulley 82 and the gears 98 for driving the gear 100th the pump 102 for the hydraulic drive of the header 22 together.
    The second drive train is composed of the second longitudinal shaft 46, the second clutch 60, the third longitudinal shaft 62 and the gears 74, 76 and the fifth longitudinal shaft 90 together.
    A connection between the first and second driveline is provided by a section 126 of the cross shaft coaxial with section 80 disposed on the other side of the bevel gear 50, a hinge shaft 128, another section 130 of the cross shaft, another bevel gear 132 with bevel gears 134, 136, a seventh Longitudinal shaft 138, the first clutch 64 and the third longitudinal shaft 62 formed.
    The operation of the drive assembly of Figure 4 is identical to that of the drive assembly of Figure 2. The fourth clutch 120 makes it possible to shut off the first internal combustion engine 36 by means of an actuator 140 operated by the controller 106 and to drive both drivelines only by the second internal combustion engine 38. However, the fourth clutch 120 could also be omitted.
