Definitions

  • the invention relates to an arrangement according to the preamble of the main claim.
  • the conventional structure of the undercarriage of a crawler excavator is such that rectangular hollow beams are provided on both sides and in the direction of the longitudinal central axis, between which the undercarriage middle part is provided with reinforcing struts and to which the aggregates of the drive are worked outwards.
  • hollow beams are often used as the basic support elements, arranged transversely to the longitudinal direction.
  • the object of the invention is to avoid this disadvantage and to be able to manufacture the construction of a crawler excavator undercarriage more cost-effectively, while at least the same operational reliability with regard to the stability of the hydraulic excavator is to be maintained.
  • FIG. 1 shows a cross section and FIG. 2 shows a plan view of a crawler excavator undercarriage.
  • the crawler excavator undercarriage builds up on both sides of the rectangular solid plate profiles 1 and 1a. Between the two profiles, the middle part of the undercarriage is shown in double-shell construction with reinforcing struts. As can be seen from the drawing, it can be designed in a dome construction for receiving the uppercarriage.
  • the plate profiles 1 and 1a are arranged upright and shown from a rectangular solid profile. These plate profiles have a considerable strength because they have to absorb the entire torsional forces of both the running gear on the one hand and that of the undercarriage center support part. They justify a considerable amount of weight, which apparently speaks against such a construction for the time being.
  • this increases the stability of the crawler excavator and it should be borne in mind that the massive design of the plate profiles per se represents cheap construction element.
  • Fig. 2 From Fig. 2 it can be seen that the plate profiles 1, 1a on both sides and in the direction of the longitudinal central axis A-A '. A section in the direction of the transverse axis B-B 'leads to the arrangement of Fig. 1.
  • Fig. 2 further clarifies that the undercarriage center support part is designed in a large area and using Fig. 1 in a double-shell construction with reinforcing struts 7, 7a, 8, 8a. This ensures that long connection weld seams can be provided for the transfer of the forces in the transition area from the shells to the plate profiles 1 and 1a.
  • the individual shells can, for. B. for assembly purposes, have openings.
  • the shells of the middle section can be constructed from welded sections for the manufacture and thus the manufacturing costs.
  • So z. B. the upper shell is composed of two halves, it then being possible to prefabricate the dome for receiving the slewing ring connection and to assemble the undercarriage center support part around it.
  • Fig. 2 also clearly shows that the support brackets 2a are worked on the outer sides of the plate profiles 1 and 1a. In the same way, it is also possible to weld the chain tensioning devices 1o, 1oa to the plate profiles 1, 1a. Ultimately, if necessary, a chain support 11 can also be accommodated by the plate profiles 1, 1a.
