Definitions

  • the invention relates to a paver according to the preamble of claim 1.
  • the object of the invention is to provide a paver according to the preamble of claim 1, which allows adjustment to different ground conditions.
  • the discharge which is suitably infinitely adjustable, can preferably be carried out to the total relief of the front in the direction of travel front wheel pair, based on the paver construction.
  • the latter also offers the advantage that the front wheels of the front Vorderradcrus burden the ground only with its own weight, which Schuachslast is reduced accordingly due to corresponding center of gravity of the paver, so that, if necessary, a permissible for road transport load (in Germany 12 t) or less can be achieved without parts must be removed and placed in the bucket in order to focus shift.
  • the paver shown in Fig. 1 comprises a mobile basic machine 1 with a rear wheel 2 (which may also be replaced by a short crawler) and two pairs of steerable front wheel pairs 3, 4, namely a front and a rear pair of front wheels 3, 4.
  • Die Basic machine 1 has on the front side a bucket 5 and on the back (not shown) distribution screw, between which a (not shown) conveyor for transporting mix to be incorporated 6 from the bucket 5 through a conveyor shaft, on which are superstructures 7, in the field of Distributor screw is arranged.
  • a screed 8 is articulated for floating installation of the mixed material to be installed via tension arms 9.
  • the screed 8 is located in the installation direction behind the area of the auger and includes a base board 10 and behind this laterally staked or independently extendable Ausfahrbohlenmaschine 11.
  • the base board 10 is usually divided in the middle, the two halves of the base board 10 for setting a roof profile transverse to Mounting direction against each other are tilted.
  • the extension screed parts 11 the base screed 10 can be widened approximately to twice its width. If an additional broadening is to be made, this is done by manually attachable screed parts.
  • Each pull arm 9 is pivoted at its front end to the base machine 1, wherein the pivot point relative to the base machine 1 - as shown - via a cylinder 12 and a guide 13 can be adjusted in height.
  • the screed 8 is also connected via hydraulic, hinged to the base machine 1 (not shown) Bohlenen somehowtlastungszylinder, which are also useful as Bohlenentransportzylinder connected to the base machine 1, which transmit a portion of the screed weight to the base machine 1 according to manual specification, which not only the Traction power is increased by the travel drive, but also the floating behavior of the screed 8 is improved, especially when installing low-load mix by a too deep sinking of the screed 8 is prevented.
  • the basic machine 1 has a drive motor 14, generally a diesel engine. This drives a hydraulic pump 15 and a generator 16 for generating electricity.
  • the hydraulic pump 15 supplies the pressure oil for subsequent units.
  • the two wheels of the rear wheel gear 2 are individually hung in the illustrated embodiment and each driven by a hydraulic drive 17 which is supplied via a manifold 18 with pressure oil from the hydraulic pump 15.
  • the wheels of the two pairs of front wheels 3, 4 are also suspended individually by providing for each wheel a vertically arranged hydraulic cylinder 19 in which a king pin 20 is vertically displaceable and further horizontally guided via a lever 21 rotatable, such as in EP 0 283 733 B1.
  • Each kingpin 20 is accordingly formed at its upper end as a piston rod, wherein located in the hydraulic cylinders 19 via the kingpin 20 hydraulic cylinder chambers 22 via compensating lines 23 transversely to the direction of travel of the paver and also via a connecting lines 23 connecting Line 24 are connected together.
  • a directional control valve 25 is arranged to the front front wheel pair 3 from the rear Vorderradbin 4 hydraulically to be able to separate, while the two wheels of the two front wheel pairs 3, 4 remain hydraulically coupled to each other via the compensation lines 23.
  • the directional control valve 25 is connected via a pressure regulating valve 26 to a pressure source 27 and a hydraulic oil sump 28.
  • the individually suspended wheels of the front wheel pairs 3, 4 can not be driven, but are preferably via hydraulic motors 29, which are supplied via a manifold 30 by a hydraulic pump 31 with pressurized oil drivable.
