  • the internal combustion engine is operated in known road pavers at a constant speed. This speed is preselected at the beginning of the installation process, in such a way that the energy generated by the combustion engine is sufficient under all circumstances to provide all drives of the paver with sufficient energy.
  • more or less energy is required at times. Because the previously made speed of the engine so be selected if it has to generate enough energy on climbing routes, too much energy is available in the area of other routes, in particular downhill stretches.

  • the invention thus differs from the previous mode of operation in that the speed of the internal combustion engine is not kept constant, but is changed depending on the load. This makes it possible to operate the engine so that it always generates only the energy currently required for the operation of the paver.
  • the paver can be operated economically.

  • a drive requires more power due to changing installation conditions, it will be supplied with the required higher energy, to such an extent that its speed or frequency remains substantially the same. If this additional energy can not be generated by the internal combustion engine with its current speed, because, for example, other drives require more energy, the speed of the engine is increased accordingly, whereby a total of sufficient energy is available again.
  • the internal combustion engine can thus be operated load-dependent at all speeds of the road paver at a speed which is sufficient to generate the energy required by the drives, in particular all the drives.
  • a control of the rotational speed of the internal combustion engine is such that its speed is continuously increased or decreased so far that it generates the energy required by all drives.

  • the speed of the internal combustion engine does not have to be changed, namely readjusted, at every speed change of the drives which are to be kept constant with regard to the rotational speed and frequency.
  • the speed is initially controlled so that it corresponds to the nominal or rated speed or is within the allowable speed range by additional energy constant to be kept drives supplied by such drives whose speed or frequency does not have to be constant.

Abstract

Les finisseuses automotrices possèdent un moteur à combustion interne (23) qui entraîne une pompe hydraulique permettant d'entraîner des moteurs hydrauliques qui servent d'organes d'entraînement (24 à 28) pour le châssis et d'autres composants de la finisseuse automotrice. Certains organes d'entraînement (24 à 28), au moins, notamment l'entraînement du châssis de la finisseuse automotrice, doivent fonctionner à une vitesse de rotation constante quelles que soient les conditions. Pour y parvenir, le moteur à combustion interne (23) des finisseuses connues fonctionne à une vitesse de rotation relativement élevée. Dans des conditions normales, cette vitesse de rotation est trop élevée, si bien que la rentabilité des finisseuses connues en souffre. L'invention prévoit de faire fonctionner le moteur à combustion interne (23) de la finisseuse avec une vitesse de rotation variable qui est régulée de manière à ce que les mécanismes d'entraînement (24, 25, 28) dont la vitesse de rotation doit rester constante restent substantiellement constants même en cas de variation de la charge et donc de la vitesse de rotation du moteur à combustion interne (23). De ce fait, le moteur à combustion interne (23) peut toujours être exploité sur la plage optimale de vitesse de rotation.
