Definitions

  • the invention relates to a sweeper for work vehicles for cleaning traffic areas according to the preamble of claim 1.
  • Sweeping devices of the generic type are known (DE-U-89 11 758), which can be attached to a work vehicle are provided. These sweepers have a Protective or support housing on which is a bristle roller covering at least on the top.
  • the Bristle roller with its axis of rotation substantially transverse to Direction of travel and is opposite in operation in the circumferential direction the direction of travel of the work vehicle by motor driven in rotation.
  • the bristle roller has a central one coaxial to the axis of rotation of the bristle roller Bearing shaft, which is an integral part of the bristle roller is.
  • the protective housing For storing the bristle roller on the protective housing is the protective housing with two side walls provided, on the one, drive-side support wall a bristle roller drive is provided with which the bristle roller is coupled in a torque-locking manner. On the side opposite the bristle roller drive the bristle roller on the second bearing-side support wall by means of a bearing pin of the bearing shaft in a removable Bearing rotatably.
  • the bearing on the bearing-side support wall be released from this and the bristle roller when lifting the entire carrying device from one side down be pivoted out of the support housing.
  • the bristle roller After loosening the torque connections between the actual bristle roller and the bearing shaft can the bristle roller from be removed from the bearing shaft and replaced with a new one.
  • the torque connection between the bearing shaft and the actual bristle roller is known in this Sweeper designed extremely expensive, so that But also loosen the assembly of this torque connection is also expensive.
  • sweeping devices are known, in which one of the supporting walls is screwed to the protective housing and to replace the bristle roller in the event of wear for example, as already for the sweeper US-A-4 926 517 mentioned above, the bearing side support wall must be completely removed so that the bearing shaft together with the bristle roller from the opposite, drive-side bearing can be pulled out and only then the protective housing or the rest of the protective housing removable with its second support wall from the bristle roller is.
