Definitions

  • the present invention relates to a wheel module which, according to the preamble of claim 1, can be fastened to an inside of a tread of a tire by means of fastening means.
  • a wheel module with a pressure sensor is known from US 4,246,567.
  • the wheel module is attached to a dome made of non-conductive material by means of bonding.
  • the dome is also bonded to the inside of the tread of a motor vehicle tire.
  • the wheel module comprises a piezo crystal designed as a pellet, which has a flat surface and expands in the direction of the rolling radius of the tire.
  • the wheel module is exposed to very high acceleration forces and the resulting bending moments.
  • the edges of the pellet can come into contact with the tire and rub accordingly, which can damage both the tire and the wheel module.
  • the wheel module according to the invention is arched on a side facing the tread of the tire, at least in the longitudinal direction, which corresponds in particular to a direction of travel of the vehicle. Due to the curvature, occurring forces and moments can be better absorbed. In addition, the rubbing of the corners of the wheel module on the tire known from the prior art can be significantly reduced in this way.
  • the longitudinal radius of the wheel module i.e. the radius of the curvature, smaller than the rolling radius of the tire. This ensures that the wheel module is not chafed against the tire, which in turn can increase the service life of the tire.
  • At least one, in particular cup-shaped, longitudinal strut is provided on the wheel module.
  • This longitudinal strut is used to absorb forces and moments that act on the wheel module.
  • this longitudinal strut is curved as part of the wheel module.
  • At least one, in particular bar-shaped, cross strut is also provided on the wheel module, which also serves to absorb forces and moments.
  • one or more cross struts can be provided.
  • the wheel module comprises a pressure sensor, this is preferably provided in the vicinity of the side of the wheel module facing the tire tread. At this point the centrifugal forces acting on the wheel module are greatest, which advantageously supports self-cleaning of the pressure membrane.
  • At least one elastic band is preferably provided as the fastening means of the wheel module on the tire, which can be threaded through the wheel module, for example.
  • the elastic band may include the wheel module in such a way that the wheel module is essentially arranged between the elastic band and the tire.
  • no opening for the belt should be provided in the wheel module.
  • the at least one elastic band can preferably be fastened to the wheel module via fixing means.
  • a fixing button or a fixing bracket can be used as the fixing means, for example.
  • the elastic band can also be attached to the wheel module by gluing.
  • the wheel module, the at least one fastening means and the fixing means are arranged on a patch or patch.
  • This patch can then be attached to the tire as a complete assembly, preferably by means of vulcanization.
  • FIG. 1 is a schematic view of a wheel module known from the prior art with a flat underside
  • FIG. 2 shows a schematic view of a wheel module according to the invention, in which the underside is curved
  • FIG. 3 is a lateral and side view of a first embodiment of the present invention
  • FIG. 4 shows a longitudinal view of the embodiment according to FIG. 3,
  • Fig. 5 shows a second embodiment of the present invention in transverse and longitudinal view and a scaled-down plan view of the patch and
  • Fig. 6 shows a third embodiment of the present invention in transverse and longitudinal view and a scaled-down plan view, which in turn shows the patch or patch.
  • FIG. 1 and 2 show a schematic view of a wheel module 1 which is fastened by means of fastening means 5 on the inside 4 of a tire tread 2.
  • the wheel module 1 can For example, data can be transmitted wirelessly to one or more transmitting and receiving antennas (not shown) arranged on the vehicle, for example.
  • the wheel module 1 can comprise at least one pressure sensor and optionally further sensors such as a temperature or an acceleration sensor (not shown).
  • the attachment on the inside 4 of the tread 2 exposes the wheel module 1 to a centrifugal acceleration a when the tire 9 rotates, which can be up to five thousand times the gravitational acceleration g (5000 g).
  • air coils with a large diameter (not shown) may be required. It is only with this specification that the energy required for operation can be transmitted during one wheel rotation. This therefore means large cross-sectional areas on the wheel module 1, on which the centrifugal forces a and bending moments B can act.
  • a further problem of the prior art shown only in FIG. 1 is that this wheel module 1 has edges or chafing points S at which contact with the tire 9 and corresponding chafing can occur, as a result of which both the tire 9 as well as the wheel module 1 can be damaged.
  • the wheel module 1 is curved according to the invention on a side 3 facing the tread 2 of the tire 9, at least in the longitudinal direction L, which corresponds in particular to a direction of travel X of the vehicle. Due to the curvature, occurring forces and moments can be better absorbed. The round transition can also significantly reduce the chafing of the corners of the wheel module 1 known from the prior art on the tire 9. Instead of In other words, an arched bearing surface of a flat bearing surface of the wheel module 1 is provided.
  • the longitudinal radius r of the wheel module 1, i.e. the radius r of the curvature is smaller than the rolling radius R of the tire 9. This ensures that the wheel module 1 is rubbed against the tire 9 at the abrasion points shown in FIG. 1
  • At least one, in particular runner-shaped, longitudinal strut 6 is preferably provided on the wheel module 1. This longitudinal strut
  • this longitudinal strut 6 serves to absorb forces and moments that act on the wheel module 1.
  • this longitudinal strut 6 is curved as part of the wheel module 1.
  • two longitudinal struts 6 are present.
  • a cavity is also advantageously created between the wheel module 1 and the tire 9, which prevents a dynamic pumping effect on the pressure sensor (not shown).
  • cross brace 7 is provided, which also serves to absorb forces and moments.
  • one or more cross struts 7 can be provided. 3 and 4, two cross struts 7 are present and bar-shaped.
  • the cross struts 7 can also be connected to the longitudinal struts 6.
  • the wheel module 1 comprises a pressure sensor (not shown), this is preferably provided in the vicinity of the side 3 of the wheel module 1 facing the tread 4 of the tire 9. At this point the centrifugal forces acting on the wheel module 1 are greatest, which advantageously supports self-cleaning of the pressure membrane of the pressure sensor.
  • At least one elastic band 11 is preferably provided as the fastening means of the wheel module 1 on the tire 9, which is threaded through the wheel module 1 in this exemplary embodiment.
  • An additional safeguard is provided, for example, by the tape 11 being glued to the wheel module 1 or being fixed by means of a fixing means, in particular a button 8.
  • This button 8 can, for example, be glued, latched or anchored to the wheel module 1.
  • FIG. 5 and 6 show two further exemplary embodiments of the present invention, in which the wheel module 1 is fastened in FIG. 5 by means of a single and in FIG. 6 by means of a double band 11.
  • the elastic band 11 in each case encompasses the wheel module 1 such that the wheel module 1 essentially lies between the elastic band 11 and the tire 9 is arranged.
  • the wheel module 1 can also be attached to the belt 11 according to FIG. 6 via a fixing bracket 10, which preferably engages around the wheel module 1 in a latching manner.
  • a patch or patch 12 is shown in a plan view in a reduced scale compared to the two respectively overlying figures.
  • the wheel module 1, the at least one fastening means 11 and the fixing means 8 and 10 are arranged on this patch or patch 12.
  • the patch 12 In the patch
  • the patch 12 can then be attached to the tire 9 as a complete assembly, preferably by means of vulcanization. In this way, the assembly can be considerably simplified. However, commercially available tires 9 can also be retrofitted with the wheel module 1.
