- Motor vehicle wheel arch including an electrical circuit and a wheel arch assembly and feed means
- the present invention relates to a wheel arch of a motor vehicle, comprising an electric circuit and an assembly of a wheel well and supply means.
- the invention relates to a wheel arch of a motor vehicle, comprising an electric circuit integrally within a vicinity of 3 mm of the wheel well.
- the tendency of car manufacturers is to equip the wheels or tires of the organ vehicles whose function is to provide information about the tires to a vehicle calculator.
- each wheel well of the vehicle is provided with an electrically conductive circuit, hereinafter referred to as an "electrical circuit", forming an antenna, connected by electrical cables to the computer and / or to a source of electricity. electrical energy while the organ is also provided with an antenna.
- the wheel arch antenna is generally integrally molded in the wheel well or glued to its surface during the manufacture of the wheel well. During the step of assembling the wheel arch on the motor vehicle, the antenna is then connected to a power supply of the vehicle by means of galvanic connections.
- connections connected to the antenna and opening out of the wheel well are often complicated to perform during the molding of the wheel arch, and are subject to particularly high fatigue due to vibration undergone by the wheel arch during normal use of the vehicle.
- these connections can be the cause of premature corrosion of the antenna which is in direct contact with the outside air via these connections.
- the invention aims to overcome these disadvantages by providing a motor vehicle wheel arch, comprising an electrical circuit integrally in a vicinity of 3 mm of the wheel arch, the manufacture and integration in the vehicle are particularly simple and robust.
- the invention relates to a wheel arch of a motor vehicle comprising an electric circuit integrally in a vicinity of 3 mm of the wheel well, characterized in that the circuit is closed.
- the electrical circuit of the wheel well of the invention is a closed circuit integrally within a vicinity of 3 mm of the wheel well. Therefore, this electric circuit, which is intended to be used as an antenna, is not galvanically connected to a power supply.
- the power supply of the electrical circuit is made by magnetic coupling.
- an electrical coupling circuit hereinafter referred to as a "coupling circuit” galvanically connected to a power supply is used, this coupling circuit being arranged facing the electrical circuit of the wheel well so as to ensure the magnetic coupling.
- the electric circuit constituting the wheel arch antenna is not galvanically connected to a power supply and can therefore be integrated in a simple way to the wheel housing during its manufacture.
- the lack of connections increases the life of the electrical circuit of the wheel arch by limiting the effects of fatigue or corrosion.
- the electrical circuit is embedded entirely in the mass of the wheel well. In this way, the electrical circuit is completely protected from external aggressions.
- the electric circuit is embedded in the mass of the wheel well, it is advantageous to provide the radially outer surface of the wheel well of at least one shaped mark so as to display the position of the electric circuit.
- This mark allows precise positioning of the coupling circuit with respect to the electrical circuit of the wheel well. The positioning accuracy is important because the geometric variation between these two circuits allows impedance matching of the electrical circuit.
- the electrical circuit is constituted by an electrically conductive wire, hereinafter referred to as "electrical wire", forming at least one closed plane loop on a tuning capacity, preferably two or three loops. .
- a tuning capacity preferably two or three loops.
- the electrical circuit being intended to be used in a particularly rigorous environment, it is advantageous that it be constituted by a coaxial wire comprising an electrically conductive central strand, an insulating sheath and a sheath. - AT -
- outer armor interrupted at the tuning capacity.
- the shielding makes it possible to have an antenna which is not very sensitive to environmental effects, for example the presence of water under the wheel arch.
- the shielding also minimizes the electric field at the origin of capacitive effects, while retaining the radiation of the magnetic field by opening the shield a few millimeters in the vicinity of the tuning capacity.
- a wheel arch according to the invention may further comprise one or more of the following features:
- the wheel arch consists of an electrically insulating material; and the electrical circuit is bonded to the surface of the wheel well.
- the invention also relates to an assembly of a wheel well according to the invention and means for supplying the electrical circuit of the wheel well.
- An assembly according to the invention may optionally comprise one or more of the following features:
- the power supply means comprise a coupling circuit disposed opposite the electrical circuit of the wheel well for magnetic coupling; and the coupling coefficient between the electric circuit of the wheel well and the coupling circuit is between 0.4 and 0.6.
- FIG. 1 shows the front of a vehicle, designated by the general reference 10.
- This vehicle 10 which is a car in the example shown, comprises mounted assemblies each constituted by a wheel 14 and a tire 16, and only the right front mounted assembly 12 is shown.
- the mounted assembly 12 is integrated with the car 10 under a wheel arch 18 of small thickness conventionally obtained by molding plastic material.
- the wheel arch 18 comprises an electric circuit 20 forming an antenna intended to interact with a member 22 carried by the wheel 14.
- the member 22 is a pressure sensor 22 fixed to the wheel 14 by conventional means.
- the pressure sensor 22 comprises transmitting and / or receiving means intended to allow a data exchange by radio with the antenna 20.
- the antenna 20 is constituted by an electric wire forming two flat loops.
- the electric wire forming the antenna is closed on itself by means of a tuning capacitor 24.
- the antenna is designed to radiate at the frequency of 13.56 MHz, its length is 350 mm, its width is 150 mm, and the distance between the loops is 15 mm.
- the total length of the electrical wire forming the antenna is about 2.5 m.
- the antenna 20 is flat and is embedded in the mass of the wheel arch 18, so that the antenna is integrally in a vicinity 26 of 3 mm of the wheel arch 18. This vicinity 26 is shown in dashed lines in Figure 1.
- the wheel housing has at least one mark 28 visible on its surface and obtained by molding.
- the mark 28 marks the center of the antenna 20.
- the antenna is provided with an outer shielding sheath 30 connected to the ground and shown in dashed lines This outer shield sheath 30 is interrupted at the level of the tuning capacitance 24 to allow the antenna 20 to radiate a magnetic field.
- the antenna 20 is supplied by magnetic coupling by means of a coupling circuit 32 arranged facing the antenna 20 of the wheel arch 18.
- the coupling circuit 32 is constituted by a conductive loop electrically connected to power supply means 34 carried by the car 10.
- the positioning of the coupling circuit 32 relative to the antenna 20 of the wheel arch 18 is obtained precisely by virtue of the reference 28 of the surface of the wheel arch 18.
- the geometric variation between the antenna 20 and the coupling circuit 32 allows the adaptation of the antenna 20 in impedance.
- the magnetic coupling is an induction coupling whose coupling coefficient is between 0.4 and 0.6.
- a coupling circuit offers the advantage of a simplicity of adjustment with respect to a galvanically coupled antenna, because coupling coupling is floating. In addition, the dielectric losses are eliminated, which makes the antenna less sensitive to external disturbances.
