Definitions

  • the invention relates to a multilayer road paver according to the preamble of claim 1.
  • Road coverings are usually formed from essentially three layers, namely a base layer, a binder layer and a cover layer.
  • the top two paving layers are installed immediately one after the other so that the top layer is applied to the still hot binder layer.
  • multilayer road finishers which permit a successive installation of the binder course and the cover layer without the binder layer of the multilayer road paver moving through the binder course before the application of the cover layer.
  • Such a known multi-layer road paver is formed from a conventional paver for the installation of only one layer and an additional device.
  • the attachment has a second, rear screed immediately behind the screed of the base paver, one of the rear screed associated distributor auger, an additional reservoir for the cover layer and a conveyor for transporting the outer layer material from the reservoir before the auger of the second screed.
  • the multi-layer paver thus formed receives an unfavorable weight distribution.
  • the base paver thus becomes tail-heavy, as it were.
  • a multilayer road paver to solve this problem has the features of claim 1. Accordingly, it is provided, seen in the direction of installation front Reservoir to assign a drive. Since the front reservoir is usually located in the front region of the chassis of the base paver, there is also the drive. As a result, the drive can provide weight compensation for the additional second screed disposed behind the landing gear and the associated auger, as a result of which the multilayer paver according to the invention obtains a balanced weight distribution.
  • the second drive is preferably provided to arrange the second drive in front of the front reservoir.
  • the drive is then seen in the installation direction at the foremost point of the multi-layer paver and thus optimally compensates the weight of the additional screed with its associated auger behind the landing gear.
  • the second drive may also be arranged below and / or next to the storage container.
  • the reservoir has a lateral recess or a bulge in the ground, which provides space for the drive under or next to the reservoir.
  • the arrangement of the drive next to or below the reservoir results in that the total length of the multi-layer finisher is not or at least not significantly increased by the additional second drive.
  • the drive is assigned its own chassis.
  • This additional chassis which is expediently arranged in the direction of installation in front of the chassis of the base paver, enables a further placement of the second drive opposite the basic paver.
  • a particularly advantageous weight compensation is brought about when both screeds are raised.
  • the screeds are lowered during operation of the multi-layer paver, the rear end of the multi-layer paver is relieved, causing the second drivetrain to imbalance in front of the base paver caught by its own landing gear.
  • the own chassis of the second drive receives when operating the multi-layer road finisher by the weight of the second drive an increased pressure on the ground.
  • the suspension assigned to the second drive can be driven effectively by the second drive.
  • the chassis for the second drive is preferably also designed as a crawler chassis.
  • the additional landing gear is designed as a tire suspension if the base paver has a tire chassis. It is also conceivable, however, to design the chassis for the second drive as a wheel gear in a tracked chassis of the base paver and vice versa.
  • the storage container, to which the second drive is assigned is supported at least partially on its own chassis of the second drive.
  • the additional landing gear carries not only the second drive, but also a part of the reservoir.
  • the reservoir thus exercises together with the second drive a weight load on the additional landing gear, which this, if it has its own drive, can transmit relatively large driving forces to the ground.
  • the second drive is provided in a preferred embodiment of the invention with an internal combustion engine.
  • the second drive preferably also has at least one hydraulic pump and / or an electric generator, which are driven by the internal combustion engine.
  • the energy of the internal combustion engine is thus converted into electrical energy or hydraulic energy, which can simply be routed to where it is needed.
  • the hydraulic pump can serve a hydraulic motor for operating the own chassis assigned to the second drive.
  • hydraulic motors and / or electric motors for operating the conveyor of the reservoir for supplying the rear screed are supplied with material, the distributor screw in front of the rear screed and the rear screed associated actuating means of the hydraulic or electrical energy generated by the second drive , It is preferably provided to drive from the second drive all components of the multi-layer road paver which belong to the additional device, with which the basic road paver is converted to the multi-layer road paver.
  • FIG. 2 shows a front part of an additional device of the multi-layer road paver of FIG. 1, FIG.
  • FIG. 3 shows a rear part of the additional device of the multi-layer road paver of FIG. 1, FIG.
  • Fig. 4 shows a second embodiment of a multi-layer road paver according to the invention.
  • FIG. 5 shows a front part of the additional device of the multi-layer road paver of FIG. 4.
  • Figures 1 and 4 show three different embodiments of multilayer road-ready for simultaneously producing two layers of a multi-ply pavement.
  • a binder layer and an overlying cover layer can preferably be produced simultaneously, that is to say in immediate succession. This makes it possible to install two layers, especially the binder layer and the cover layer, "hot-on-hot", without the binder layer having to be run over before the application of the cover layer.

This drives hydraulic motors or electric motors for the subsequently described components of the rear auxiliary device 12 of the multi-layer paver.
  • the rear auxiliary device 12 has a second screed 24, which may be a compactor screed, in particular high-compression scoop, which is arranged behind the front screed 15 and is referred to below as the rear screed 24.
  • the rear screed 24 is associated with a distribution screw 25, which is thus located between the front screed 15 and the rear screed 24.

Abstract

Des finisseurs multicouches disposent de deux tables de pose (15, 24) montées derrière leur train de roulement à chenilles (14). Du fait des tables de pose (15, 24) disposées en arrière du train de roulement à chenilles (14) dans la direction de pose (13), le finisseur multicouche est lourd de l’arrière. Cela présente plusieurs inconvénients. Selon l’invention, un deuxième entraînement (18) du finisseur multicouche est disposé devant, à côté et/ou en dessous d’une trémie avant (17) du finisseur multicouche. Ce deuxième entraînement (18) se trouve ainsi devant le train de roulement à chenilles (14), donc sur le côté opposé aux tables de pose (15, 24). Le deuxième entraînement (18) contribue ainsi à améliorer la répartition pondérale du finisseur multicouche.
