Definitions

  • the present invention relates to a multi-part wheel rim for a vehicle, in particular for an agricultural work machine.
  • Conventional wheel rims in particular for use on agricultural work machines, consist of a wheel plate (or wheel disc) and a wheel rim ring. Often, these two components are welded.
  • the wheel By means of the wheel plate of a one-part wheel rim, the wheel (i.e. a tyre with a wheel rim) is conventionally fastened to a wheel hub of a vehicle.
  • the tyre is pulled onto the wheel rim ring and fixed laterally on the wheel by outer-lying wheel rim flanges on which the tyre bead bears.
  • the region of the wheel rim ring which lies closest to the wheel axis is also referred to as the wheel rim bed.
  • the tyre bead must be pulled over the wheel rim flange when mounting the tyre and in the case of large tyres and large wheel rim flange heights this is possible only using special tyre mounting machines, which are widely known.
  • two-part rims can be employed such as that disclosed in US-4,043,374.
  • such two-part rims do not lend themselves well to accepting auxiliary bodies employed to provide extra weight for example.
  • a wheel rim which is adapted to be mountable on a hub, having a wheel rim bed and an inner and outer wheel rim shoulder, wherein the wheel rim can be assembled at least from a first wheel rim part and a second wheel rim part, characterised in that an intermediate ring is provided, which is essentially flat on its outer circumference in order to be able to fit an auxiliary body.
  • an auxiliary body can easily be fitted onto the intermediate ring since the auxiliary body does not need to be pulled over any protrusion or the like.
  • the auxiliary body can thus be used variably and replaced without any problems.
  • the inflation volume of the tyre may be reduced by a suitable auxiliary body, which allows more rapid inflation of the tyre.
  • a solid body made of rubber would have emergency backup properties even in the event of complete pressure loss of the tyre.
  • the intermediate ring itself may also be designed as an auxiliary body, by the intermediate ring essentially extending radially outwards.
  • This design reduces the number of components and therefore the costs.
  • the operating reliability of the system is increased.
  • the intermediate ring increases the wheel weight so that better road holding of the vehicle is achieved.
  • the auxiliary body may also be designed as a hollow body.
  • the auxiliary body may for example be filled with water as an additional wheel weight.
  • the hollow body may however also serve as an air reservoir. In each case, the internal volume of the tyre is reduced, which allows more rapid inflation.
  • Fastening elements which connect the wheel rim parts, may be releasable from the inside of the wheel rim.
  • the wheel rim can therefore merely be taken off the hub from the outside.
  • the fastening elements, which hold the multi-part wheel rim together in this case, cannot be released inadvertently. An application error is therefore impossible and the risk of injury is reduced.
  • This releasable component connection allows rapid and uncomplicated mounting/removal of the tyre with the aid of a standard tool.
  • An intermediate ring may be formed integrally on one of the two wheel rim parts.

  • the two wheel rim parts 5, 6 enclose the intermediate ring 7 in their middle.
  • the first wheel rim part 5 comprises a section, also referred to as a wheel plate 5a, standing perpendicularly to the wheel axis Y (cf. Fig. 2). At its lower end, first through-bores 5f are distributed over the wheel rim circumference with a constant mutual spacing on a first sub- circle 8 and threaded bores 5d are distributed over the wheel rim circumference above these on a second sub-circle 10.

  • Fig. 2 is furthermore shorter in the wheel rim part 6 than in the wheel rim part 5.
  • the number of threaded bores 5d is equal to the number of through-bores 6d.
  • the wheel rim part 6 furthermore extends in a stepped fashion in this representation, in three stages here towards the top right, and it ends with a second wheel rim flange 6c on which the tyre 2 bears.

  • the resulting fits are configured radially free of play.
  • the anchoring screws consist of a threaded shaft and a screw head 9a.
  • the screw heads 9a are provided on the inside of the wheel rim 3. In this way, they are not accessible from the outside. This prevents a user from inadvertently releasing the screws without previously letting the air out of the tyre 2 and the user being injured by the pressurised system.
  • Fig. 3 furthermore shows a hub 4.
  • threaded bolts 4a are distributed on the first sub-circle 8 over the circumference of the hub 4 with a constant mutual spacing.
  • the number of threaded bolts 4a is the same as the number of threaded bores 5d in the wheel rim part 5 and they are distributed with the same distribution over the circumference on the same first sub-circle 8.

  • the hub mating surface 4b is engaged with a corresponding first wheel rim part hub-mating surface 5g of the first wheel rim part 5.
  • the hub 4 furthermore has a second hub mating surface 4c on the inside.
  • the hub mating surface 4c is engaged with a corresponding second wheel rim part hub-mating surface 6g of the second wheel rim part 6.
  • the two described fits are configured radially free of play.
  • the wheel rim 3 is secured by wheel nuts 1 1, which are screwed onto the threaded bolts 4a.
  • the wheel nuts 11 are accessible from the outside of the vehicle.
  • the screw heads 9a of the anchoring screws 9 for connecting the individual wheel rim parts are provided on the inside of the hub 3, [so] that the user can only release the externally accessible wheel nuts 1 1 and any risk of confusion is impossible.
  • the wheel rim 3 can readily be mounted on the hub 4.
  • mounting/removal of the tyre 2 is also possible without special tyre mounting machines since the tyre 2 does not have to be pulled over the wheel rim flange 5c, 6c.
  • Fig. 4 shows the wheel rim 3 in quarter section with an auxiliary body 12.
  • the auxiliary body 12 for example in the form of an annular auxiliary body 12, can easily be mounted initially on the intermediate ring 7 before the wheel 1 is completed by mounting the first and second wheel rim parts 5, 6, since the intermediate ring 7 does not comprise any elevation jutting out radially from the wheel axis Y (cf. Fig. 2) on its two ends 7b.
  • the additional weight of the auxiliary body 12 increases the wheel weight of the vehicle, so that better road holding is achieved.
  • Fig. 5 shows a wheel rim characterised in that the intermediate ring 7 itself is designed as an auxiliary body essentially extending radially outwards.
  • the intermediate ring 7 is formed of steel and is annular with a rectangular section. Again, the wheel rim bed section 7a is flat so as to receive a further auxiliary body if required.
  • Fig. 6 shows a further embodiment of a wheel rim 3 in quarter section.
  • the first wheel rim part 5 and the second wheel rim part 6, however, are respectively configured in two parts in this embodiment.
  • the first wheel rim part 5 comprises a first section 5.1 and a second section 5.2
  • the second wheel rim part 6 likewise comprises a first section 6.1 and a second section 6.2.
  • the first section 5.1, 6.1 is connected by a material fit, preferably welded, to the second section 5.2, 6.2.
  • Section 5.1 and section 6.1 are therefore identical components, which is advantageous for mass production and reduces costs.
  • Fig. 7 shows a wheel rim according to the invention in two-part form. With respect to Fig. 3, the only difference in this embodiment is that the wheel rim parts 6, 7 are configured in one piece as a wheel rim part 67.
  • the screw heads 9a of the anchoring screws 9 should then be designed so as to preclude any risk of confusion with the wheel nuts 11. This may for example be done by using larger spanner widths or special nuts.
  • the intermediate ring 7 could be configured with a very large wall thickness in order simultaneously to serve as a wheel weight or reduce the inflation volume of the tyre.
  • the intermediate ring 7 would therefore at the same time fulfil the function of the auxiliary body 12. The wheel weight would thereby be increased further.
  • the intermediate ring could also be vulcanised with rubber, in order to reduce the inflation volume of the tyre 2. In this case, it is possible to produce a solid or hollow body.
  • the intermediate ring could furthermore be configured as a hollow body instead of a solid body, so that its interior could serve as an air reservoir or as a reservoir to be filled with water, i.e. as an additional wheel weight.
  • the first through-bores 5f and the threaded bolts 4a, as well as the threaded bores 5d and the second through-bores 6d, must respectively have the same distribution.
  • the mutual spacing may vary.
