Definitions

  • the invention relates to a refuse compacting vehicle according to the preamble of claim 1.
  • a bolt with a central groove is provided on the pin of the supporting part to secure the shoe, in which a spring element engaging transversely to the longitudinal extension of the bolt engages.
  • a spring element engaging transversely to the longitudinal extension of the bolt engages.
  • a certain preload may be generated by the resilient element, but this force is only used to press the upper end face of the recess of the shoe against the upper end face of the pin.
  • this inevitably means wear between the end face of the pin and the correspondence surface of the shoe, so that undesired wear and greater play is possible there.
  • a further disadvantage is that the two elements required to hold the shoe have to be mounted from different directions of operation, the one element also having to be arranged before the shoe is put on. Furthermore, due to the abutment of the end face of the pin on the end face of the recess of the shoe and because of the formation of play between the side walls of the shoe and the holder, considerable noise is inevitable when driving the refuse compacting vehicle.
  • the invention has for its object to provide a garbage compacting vehicle of the generic type, which allows a high level of functionality, excellent smoothness and a good support function in the event of transverse and longitudinal loads with uncomplicated shape, simple assembly and low use of materials.
  • the combination according to the invention results in a reduction of the individual parts, since now only one dowel pin is sufficient as a securing element for holding the shoe on the supporting part pin.
  • the parallel offset arrangement of the mounting holes for the dowel pin creates a pretension in the plug-on direction, which on the one hand serves to secure the position and on the other hand also leads to the fact that noise is largely reduced.
  • these cams 3 each consist of a support part 4 to be fastened to a wheel 2 and a shoe 5 detachably fitted onto the latter, which complement each other to form a truncated pyramid-shaped body.
  • a radially directed, integrally formed pin 6 strives from the supporting part 4 fastened to the wheel 2, in particular welded on, which engages in a slot 5 arranged in the shoe 5 and adapted to the pin 6 without play and in a rotationally fixed manner.
  • the pin 6 and the insertion opening 7 have a rectangular cross section with rounded corners over their entire length in the direction of the push-on direction.
  • the pin tapers 6 steadily towards its free end.
  • the wedge angle is outside the self-locking range in order to be able to detach the attached shoe relatively easily from the pin 6.
  • the pin 6 has at its base a smaller area than the supporting part 4 and is arranged offset on all sides towards the center forming a step 8 so that the side walls forming the insertion opening 7 of the shoe 5 up to the shoulder 8 can be made equally thick.
  • the free edges of the aforementioned side walls are arranged with play to the shoulder 8.
  • the depth of the insertion opening 7 is greater than the insertion length of the pin 6.
  • a cylindrical pin 9, preferably designed as a dowel pin, is provided, which extends through cylindrical bores 10 and 11 arranged in the shoe 5 as well as in the pin 6.
  • the latter are offset parallel to each other so that the pin 9 driven with static friction exerts effective tensioning forces on the shoe 5 in the direction of its attachment direction.
  • the side walls 12 of the shoe 5 penetrated by the bores 10 are extended beyond the free edges thereof compared to the bore-free shoe side walls 13.
  • According to the side wall extensions 4 recesses 14 are provided in the support part.
  • the width of the side wall extensions is tapered symmetrically in the direction of the base side 15 of the supporting part 4 and the axes of symmetry cross the bores 10 in order to still have sufficient material in the area of the bores with the least possible material expenditure, so that, among other things, when driving in the bolts 9 Bores 10 are not destroyed, and in order to be able to perform a supporting function in the event of longitudinal or transverse loading.
  • a material-saving recess 16 opening out at the base side 15 is provided in the support part 4, which recess widens steadily towards the base side, in order to cover both the support part 4 and the shoe 5 in one piece, preferably by die forging, with the exception of the bores 10 and 11 or to be able to produce castings.
