Definitions

  • the invention relates to a road finisher according to the preamble of patent claim 1, and to methods according to the preambles of claims 9, 10 and 11.
  • Paver ( EP 1 118 714 A . EP 0 489 969 A ) have at least temporarily high power required heating devices or high-performance electric motors, z.
  • the internal combustion engine drives a plurality of hydraulic pumps, including a driving pump unit, via a pump distributor gearbox, which define powerful functional assemblies with correspondingly hydraulic motors or hydraulic cylinders distributed in the road paver and / or the screed.
  • All functional assemblies are permanently driven by the crankshaft of the internal combustion engine via a torsionally elastic coupling, eg via the pump distributor gearbox, and generate high drag loads for the internal combustion engine.
  • the towing loads complicate the starting process of the internal combustion engine.
  • the engine Even during a heating phase of the heaters, which are to be brought to operating temperature before the start of the paver, the engine must first overcome the drag loads actually not required function modules, which prolongs the heating inconvenient and increases fuel consumption.
  • the road paver should drive as efficiently as possible in a transport phase, which is made more difficult by the drag loads of the function modules that are not required, ie, the maximum transport speed is limited and the fuel consumption is increased.
  • In such operating phases are still mechanical and hydraulic power losses in the gear stages and / or power split and in the hydraulic system are added, which are noteworthy especially for cold gear or hydraulic oil, and demand more power from the engine, as would actually be required for these operating phases.
  • transfer gearbox having at least one permanently drivable power split and optionally switched on and off power splits.
  • the requirements for agricultural machinery are not comparable with those occurring especially in road pavers, which include, inter alia, the material to be installed, its heating and dosing, and the drive, heating and control of the installation of the material to be operated functional modules in the paver and / or Screed be dictated.
  • the invention has for its object to provide a paver of the type mentioned above and methods to improve the energy balance and environmental impact with regard to specific requirements in the operation of a paver.
  • At least one pump can be uncoupled while the generator is permanently driven, e.g. in order not to jeopardize the operational readiness of the paver or to supply heating devices, and the at least one decoupled pump remains uncoupled for a longer period depending on the operating situation, the towing load for the internal combustion engine is noticeably reduced.
  • the internal combustion engine starts more easily, optionally completes its warm-up phase more quickly, more quickly completes a heater heating phase via the generator, allows the operating temperature of heated working components to be maintained at lower fuel consumption, and consumes significantly less fuel during transport or during a waiting phase for a new batch of material as before.
  • a heating phase of electrical heaters is further optimized performance feasible. Overall, taking into account the specific requirements of operating a paver in certain operating situations by uncoupling at least one pump significantly saved fuel, relieves the environment and reduces the maintenance frequency. At standstill of the road paver even the driving pump unit can be disconnected.
  • a transport phase is feasible with higher transport speed and favorable fuel consumption, if only the drive pump unit required for driving is driven, and also the generator is driven, while other pumps for the transport phase are uncoupled hydraulic pumps of functional assemblies.
  • the towing load of the generator is possibly negligible anyway in the transport phase anyway.
  • At least one hydraulic pump When starting and possibly warming up the internal combustion engine is at least one hydraulic pump, or all unused hydraulic pumps are disconnected, so that the engine starts easier and faster to operating temperature, and has less specific fuel consumption.
  • the generator and the hydraulic pumps of the functional assemblies are driven jointly by the crankshaft via a torsionally flexible coupling, which strips the internal combustion engine or its flywheel against torsional impacts.
  • the generator and the pumps are compactly combined at one end of the engine, possibly including a pump distributor gearbox with power splitters.
  • a permanent output train is provided between the crankshaft and the driving pump unit, and there is the shiftable coupling between the crankshaft and the pump distributor gearbox for the pumps of the functional assemblies.
  • the switchable coupling is preferably arranged on or in the pump distributor gear.
  • the driving pump unit can be flanged to the pump distributor gearbox, and is permanently driven by the combustion engine through the output train through the pump distributor gearbox.
  • the shiftable clutch is expediently disengaged while the paver executes a transportation journey and / or is started or the engine warms up or heaters are brought to operating temperature or held.
  • the generator and the driving pump assembly are permanently drivable together via the output train, while at least one pump can be disconnected from further functional assemblies via the at least one shiftable clutch.
  • the driving pump unit is operated for transport, while other pumps are disconnected. If necessary, the generator generates, if necessary, only a negligible towing load during transport travel and can, if necessary, supply heating devices or other electrical consumers as required.
  • all arranged on the pump distributor gear pumps, including the driving pump unit can be uncoupled together via the switchable coupling. It is only a single switchable coupling required, which disengages the towed loads in the disengaged state and is designed so that it does not damage in the disengaged state for a long time.
  • individual switchable clutches are arranged between the crankshaft of the internal combustion engine and the pumps for functional assemblies, possibly including the driving pump unit.
  • These individual switchable couplings are preferably located on or in the pump distributor gearbox or in its power branches to the pumps of the functional assemblies. It can be uncoupled as required, the towing load of a particular function module or the drag loads of several or all functional modules, for example, to improve the starting behavior of the engine, the transport journey to perform quickly and with more favorable fuel consumption, or bring the heaters as quickly as possible to operating temperature.

If the generator is mounted separately from the pump transfer case in the chassis of the paver, a favorable, for example, in terms of weight distribution position of the generator can be selected, and the pump distributor gear is released from the load of the generator.
  • the belt drive allows operation of the generator with a favorable for optimal power output speed.
