Definitions

  • the present invention relates to a drive device according to the preamble of claim 1, as well as a working machine device according to the preamble of claim 12.
  • the DE 94 00 147 U is considered to be the closest prior art.
  • the EP 2 317 097 is considered as state of the art under Article 54 (3) EPC.
  • pump transfer cases are provided, both at least one hydraulic pump, and at least one working machine, such as a crusher, drive.
  • the hydraulic pump in turn drives, for example, a hydraulic motor, which drives, for example, the chassis of the tree rail.
  • the work machine is usually driven by a wedge disk and a corresponding belt drive, wherein between the output of the pump distributor gear and the wedge disk, a fluid coupling is interposed.
  • the object of the present invention was therefore to reduce the burden on the drive device in case of failure.
  • this object is achieved by a drive device with the characterizing features of claim 1.
  • the fluid coupling and the Downstream wedge disk and possibly downstream machine are subjected to a torque or the torque curve are interrupted.
  • reacts much faster to a fault and the torque flow between the pump distributor gear and wedge disk or downstream machine can be interrupted quickly by the clutch.
  • the clutch for example as a friction clutch, the torque transmission for the downstream components, for example, can be ramped up slowly, so that can represent a predetermined starting over the clutch, whereby, for example, a gentle start-up realized and the life of the drive device can be increased.
  • the hydraulic pump is connected via a clutch for transmitting a rotational movement or torque with the pump distributor gearbox.
  • the hydraulic pump can be used, for example, to drive a hydraulic motor.
  • the hydraulic motor can be used for example for driving wheels or track of a construction machine.
  • the hydraulic pump can optionally be switched on and off, for example, to avoid the idling losses of the hydraulic pumps during the actual operation "breaking". This reduces the energy consumption of the entire drive device.
  • the drive means is connected via a flexible coupling with the pump distributor gearbox.
  • the elastic coupling can once have the function of a "damping clutch” and once that of a “compensating clutch”.
  • At least one further hydraulic pump is connected via an associated clutch with the pump distributor gearbox.
  • the wedge disk between the clutch and the fluid coupling is arranged, wherein the wedge disk is deposited on bearings on the housing of the pump distributor gear.
  • the pump distributor gearbox comprises a gear stage, in particular a one-stage or multi-stage gear stage with a ratio i equal to 1 or i not equal to 1.
  • a gear stage in particular a one-stage or multi-stage gear stage with a ratio i equal to 1 or i not equal to 1.
  • the fluid coupling is a hydrodynamic coupling operating according to the Föttinger principle.
  • the coupling parts of the input and output side are not mechanically connected to each other. Rather, in particular a fluid serves as a torque transmitting means.
  • the clutch works wear-free and limits the starting and maximum torque in the drive train. Furthermore, it serves as a start-up aid for the engine, as overload protection in case of failure and for torsional vibration separation.
  • the clutch for the wedge plate is received in the housing of the pump distributor gearbox.
  • a compact drive means can be provided.
  • a friction clutch with suitable for "wet run” coverings is preferably used.
  • Wet-running multi-plate clutches for example, build much smaller than dry friction clutches with the same power transmission.
  • Wet running linings are considered as appropriate during dynamic acceleration processes Wear / design wear-free, while dry running pads are always subject to wear.
  • Another object of the present invention has been to propose an improved working machine device, in particular to propose a working machine device whose loads can be reduced for the working machine device in case of failure.
  • the drive device of the working machine device is a drive device according to at least one of claims 1 to 11 enables the advantages of the drive device according to the invention to be used for the working machine device according to the invention , ie the load of the working machine device can be reduced for the accident, since the torque flow through the clutch can be interrupted quickly. Since it is possible to represent a predetermined starting process via the clutch, it is also possible, for example, to realize a gentle starting of the working machine device and to extend its service life.
  • a drive device essentially comprises a drive means 1, a pump distributor gear 4, a clutch 4a, at least one hydraulic pump 5, a fluid coupling 6, and a wedge disk 7a. Also, the drive means may comprise a further clutch 4b.
  • a working machine device essentially comprises a drive device according to the invention, as well as a working machine 9. Furthermore, the working machine device according to the invention comprises a wedge disk 7c and a corresponding belt drive 7b for connection to the wedge disk 7a of the drive device.
  • the drive devices described above are usually carried out with a diesel engine or with an electric motor. But also more drive means are possible. The following description is based on the example "Diesel engine as drive means" (see FIG. 1 ).
  • the pump distributor gear 4 is flanged.
  • the diesel engine 1 is mounted, for example, on the frame of a mobile construction machine (not shown) with corresponding fastening elements 2a / 2b.
  • the pump distributor gear 4 can also be fastened to the frame of the construction machine with corresponding fastening elements 2c.
  • the pump distributor gear has a housing 12.
  • a flexible coupling 3 can be flanged, which in turn is arranged on a transmission input shaft 10 of the pump distributor 4.
  • the elastic coupling 3 once has the function of a "damping clutch” and once that of a "compensating clutch".
  • the torque flow between the transmission input shaft 10 and a transmission output shaft 11 of the pump distributor gear 4 is to be interrupted or connected with a shiftable clutch 4a.
  • the actuation of the switchable couplings 4a / 4b to 4i is not relevant to the function here and can therefore be chosen arbitrarily.
  • Common types of operation are hydraulic or pneumatic pressure, electromagnetic force, spring force, mechanical operations, etc.
  • the following descriptions refer to couplings that are actuated by hydraulic pressure.
  • the transmission input shaft 10 and the transmission output shaft 11 are mounted with bearings in the housing 12 of the pump distributor gear 4.
  • On the transmission output shaft 11 of the pump distributor gear 4 is a working according to the "Föttinger principle" fluid coupling 6, also called hydrodynamic coupling (eg, with constant oil filling) plugged.
  • the gearbox output torque of the pump distributor gear 4 is thus at the same time the drive torque of the fluid coupling 6.
  • the fluid coupling allows the following inertia and possible load moments, which high loads for switchable Couplings mean, for all components, such as the friction elements of the switchable clutch, all torque-transmitting components and connections such as: shafts, gears, feather key connections, screw, clamping set connections, splines, are gently accelerated.
  • the wedge plate 7a On the output side of the fluid coupling 6, the wedge plate 7a is attached.
  • This wedge disk 7a is spatially seen in the first preferred embodiment of the invention shown here between the pump distributor gear 4 and the fluid coupling 6 and is mounted on the housing 12 of the pump distributor gear 4 via bearings.
  • the belt drive 7b can now, as exemplified in FIG. 1 shown, a work machine, such as crusher 9, drive via a second wedge disk 7c.
  • flat belts are also considered instead of the V-belts.
  • a start-up process with the previously outlined drive device or work machine device can be designed as follows.
  • the components used have the following state.
  • the diesel engine 1 is not started, the clutch 4a, in particular the switchable Friction clutch 4a, is open, ie without pressure and the torque flow between the transmission input 10 and transmission output 11 is thus interrupted, the machine is preferably load torque-free (in the example described, the crusher 9 is empty) and also the optional, switchable clutches 4b to 4i can be opened ,
  • the diesel engine 1 is now started first. Then it is raised to the switch-on speed (eg idle speed, "increased" idle speed, oa) of the switchable clutch 4a.
  • the shiftable friction clutch 4a is turned on, that is, the clutch 4a is subjected to hydraulic pressure and the torque transmission between the transmission input shaft 10 and the transmission output shaft 11 is thus produced.
  • the unit pump distributor gear 4 and switchable couplings 4a / 4b to 4i is a self-sufficient assembly.
  • individual, several or all of the optional switchable clutches 4b to 4i can be switched on in order to drive the hydraulic pump (s) 5 / 5a to 5i).
  • the pressure level can now be increased to eg the operating pressure.
  • the height of the transmittable torque of the shiftable friction clutch 4a is adjustable.
  • the diesel engine 1 can be brought to a higher speed level, eg operating speed.
  • the following inertia and possible load moments which mean high loads for switchable clutches, are now gently accelerated for all components.
  • the previously described unit is part of a modular system; ie in drive devices in which lower load conditions (lower mass moments of inertia to be accelerated, no or only small load moments, etc.) occur, it is also possible to accomplish the startup process only via the shiftable friction clutch 4a.
  • the fluid coupling 6 can be omitted from the unit and the transmission output shaft is connected via adapter flanges directly to the wedge disk 7a.
  • the kit offers the use or the waiver of an elastic coupling 3 and / or the switchable clutches 4b to 4i for switching on or off of the hydraulic pump (s).
  • a further embodiment of the drive device according to the invention or the working machine device according to the invention is in the Fig. 2 shown.
  • the drive device according to Fig. 2 differs from the drive device according to Fig. 1 in that the wedge disk 7a is not arranged between the shifting clutch 4a or the outgoing shaft 11 of the shifting clutch 4a and the fluid coupling 6, but the wedge disc 7a is deposited directly on the fluid coupling 6.
  • the output side of the fluid coupling 6 consists of a wedge disk 7 a which is mounted on a hollow shaft of the fluid coupling 6.
  • a further embodiment of the drive device according to the invention or the working machine device according to the invention is in the Fig. 3 shown.
  • the drive device according to Fig. 3 differs from the drive device according to Fig. 1 and Fig. 2 in that the main drive is no longer guided directly through the pump distributor gearbox 4, but experiences a misalignment with the driving machine via a gear stage (1, 2 or multi-stage with i equal to 1 or i not equal to 1).
  • This can analogously to the embodiment according to Fig. 2 , as shown, but also analogous to Fig. 1 , that is, with the arrangement of the wedge disk 7a proposed there, be implemented.
  • one of the intermediate shafts could be used to drive a hydraulic pump.
