Definitions

  • the invention relates to a chassis component of a vehicle, having a magnet and at least one electrical coil which interacts with the magnetic field caused by the magnet, the magnet and the coil being movable relative to one another.
  • Electronic control systems which also require sensor systems on the moving parts of the axles, are increasingly found in chassis of motor vehicles.
  • sensors in the moving parts of the axles have the disadvantage that a cable connection from the body to the sensor is required, which harbors the risk of the cable breaking.
  • radio systems are increasingly being used to transmit the signals emitted by the sensor.
  • sensor systems with integrated signal processing have a relatively high power consumption, so that energy transmission via a radio link can be assessed as bitic.
  • a power supply via a battery is possible, but this has the disadvantage that a battery has to be replaced during the course of a vehicle's life and additional maintenance work is therefore required.
  • DE 195 20521 AI discloses a locating system for vehicles, with a locating device which has a battery, a charging circuit connected to the battery and a device connected to the charging circuit in which a random vibration movement from normal vehicle locomotion is converted into electrical energy.
  • a support structure is held between two spiral springs in a housing of the device, so that in response to an oscillation movement, a back and forth movement of the support structure relative to the housing in the direction of an oscillation axis is possible.
  • Magnets are attached to the side walls of the support structure and are opposite coils arranged on the side walls of the housing.
  • DE 198 16 454 AI discloses a device for monitoring vehicle tires, with a probe, the movement of which is transmitted via a rod to a permanent magnet which induces a voltage in a coil surrounding it.
  • Voltage is rectified and smoothed and then fed to a storage capacitor.
  • the device is arranged in the vehicle tire, the button being actuated only when the tire pressure is too low.
  • DE 199 34 263 AI discloses a structural unit for a vehicle, with a sensor, evaluation electronics, radio transmission and its own power supply, which uses the relative movement between a magnet and a coil and stores the electrical energy obtained in a capacitor.
  • the unit can be arranged with a component connected to the axis.
  • the object of the invention is to further develop the chassis component of the type mentioned at the outset in such a way that electrical energy is generated as continuously as possible while the vehicle is traveling.
  • Undercarriages of vehicles in particular motor vehicles, usually have a wheel, a spring-damper unit and connecting elements, such as Handlebar, on.
  • These undercarriage components regularly have at least one natural frequency with which they vibrate with each shock-like excitation of the undercarriage. Since shock-like excitations occur very often when the motor vehicle is in motion, these oscillating chassis components vibrate quasi-continuously with their natural frequencies when the vehicle is in motion. Coupling of these vibrations into the body is prevented by appropriate damper elements.
  • the chassis component according to the invention makes use of these vibrations and has a magnet and at least one electrical coil which interacts with the magnetic field caused by the magnet, the magnet and the coil being movable relative to one another.
  • the undercarriage component can carry out vibrations with at least one natural frequency, the magnet being fastened to a spring and being able to be moved relative to the coil.
  • the natural frequency of the oscillator having the magnet and the spring is matched to the natural frequency of the chassis component.
  • the chassis component carries out an oscillation with its natural frequency or with one of its natural frequencies, as a result of which the oscillator formed by the spring and the magnet is also excited to oscillate. Due to the oscillation of the magnet, an electrical current or an electrical voltage is generated in the coil, so that electrical energy can be provided or supplied quasi-continuously by the chassis component according to the invention during the journey.
  • the natural frequency of the oscillator is particularly dependent on the mass of the magnet and the spring constant of the spring, so that the natural frequency of the oscillator can be matched to the natural frequency of the chassis component by a suitable selection of the magnetic mass and the spring constant.
  • the oscillator should be as small as possible compared to the dimensions of the undercarriage component or have as small a mass as possible compared to the mass of the undercarriage component, so that the effects of the oscillator on the vibration properties of the undercarriage component are low.
  • the term coordinated means that the natural frequency of the
  • the chassis component can e.g. be designed as a handlebar or as a joint. However, it is also possible for the chassis component to be composed of a group of individual components which, as an assembly, has one or more natural frequencies. A vehicle wheel or tire can also be part of such an assembly.
  • the magnet is in particular guided in a linearly displaceable manner in a sleeve, so that the magnet can only oscillate in the direction of the longitudinal axis of the sleeve.
  • the magnet is preferably fastened in a sliding element so that the outer surface of the sliding element is in sliding contact with the inner wall of the sleeve. This has the advantage that the friction between the sleeve and the sliding element can be set very low by a suitable choice of material and a suitable surface treatment.
  • the sliding element and / or the sleeve are preferably made of a non-magnetic material, so that the magnetic field of the magnet is affected as little as possible.
  • the spring can be designed as a helical spring, which is arranged in particular concentrically around the sleeve.
  • the spring is preferably axially fixed between outer shoulders arranged at the ends of the sleeve and can be biased in the longitudinal direction.
  • Mounts can be formed on the sliding element, which reach through the wall of the sleeve and are fastened to the spring.
  • longitudinal slots can be provided in the wall of the sleeve, through which the holders extend.
  • the sleeve is preferably designed in two parts, with a distance between the two sleeve parts being provided in the axial direction. This distance is in particular smaller than the longitudinal extent of the sliding element and is penetrated by the brackets.
  • each coil can have a magnetic core
  • the two cores can be connected to each other via a housing made of magnetic material.
  • This arrangement favors the magnetic field profile, the magnetic material being in particular a ferromagnetic material.
  • the magnet, the spring and the two coils as well as optionally the sliding element and the sleeve can be arranged in the housing, so that the oscillator is protected against the ingress of dirt and moisture.
  • the end faces of the housing are preferably closed by the two coils or by the coil cores.
  • An electrical generator is formed from the oscillator and the coils, and the electrical energy generated by it can be stored in a capacitor.
  • Super-cap capacitors are particularly suitable for this because they can store large amounts of electrical energy. Furthermore, it has proven to be advantageous to use supercap capacitors with a small nominal voltage of, for example, 2.3 V. If the electrical generator is used to power a sensor, for example, a charge pump can be used which raises the voltage to the desired level so that a sufficiently stable power supply is guaranteed.
  • a rechargeable battery can also be used as an electrical energy store, it being possible for a battery charger to be connected upstream.
  • FIG. 1 shows a sectional view of an embodiment of the chassis component according to the invention
  • FIG. 2 shows a first electrical block diagram for the embodiment according to FIG. 1
  • FIG. 3 shows a second electrical block diagram for the embodiment according to FIG. 1.
  • FIG. 1 shows an embodiment of the chassis component according to the invention, a magnet 2 fastened in a sliding element 1 being mounted in a sleeve 4 so as to be slidable in the direction of its longitudinal axis 3.
  • Magnetization of the magnet 2 designed as a permanent magnet runs on or parallel to the longitudinal axis 3, the north pole N and the south pole S of the magnet 2 being shown in the figure.
  • the sleeve 4 is formed in two parts, a distance 5 being provided in the axial direction between a first sleeve part 4a and the second sleeve part 4b, which is penetrated by a holder 6 arranged on the sliding element 1.
  • This holder is fastened between two turns 7 of a spring 8 designed as a helical spring, which is arranged concentrically around the sleeve 4.
  • An outer shoulder 9 is formed at each of the two ends of the sleeve 4, the spring 8 being inserted under axial prestress between these two outer shoulders 9.
  • the sleeve 4 is arranged between two electrical coils 10, each of which has a core 11 and is fastened to it, each core 11 extending into the interior of the respective coil 10 and partially encompassing it on the side facing away from the magnet 2. Both cores 11 are connected to one another via a housing 12, which is closed on the end face by the cores 11. The cores 11 and the sleeve 4 are fixed to the housing 12.
  • the housing 12 or one of the cores 11 is fastened to the chassis component 13, which is shown schematically and can vibrate with at least one natural frequency, so that mechanical vibrations of the chassis component 13 can be passed on to the housing 12 or to the core 11.
  • the oscillator 14 indicated by dashed lines and having the spring 8 the magnet 2 and the sliding element 1 can be excited to vibrate in order to induce an electrical current or an electrical voltage in the coils 10.
  • Magnets 2 and the sliding element 1 are selected such that the natural frequency of the oscillator 14 is matched to one of the natural frequencies of the chassis component 13.
  • the magnetic coupling between the electrical coils 10 and the oscillator 14 can lead to damping of the oscillating system, which can be taken into account in the design of the oscillator 14. In many applications, however, this retroactive effect is negligible.
  • the sliding element 1 and the sleeve 4 are preferably made of a non-magnetic material, whereas the cores 11 and the housing 12 can consist of a magnetic, in particular a ferromagnetic material, which contributes to the flux concentration.
  • FIG. 2 shows an electrical block diagram for the embodiment according to FIG. 1, the electrical generator 15 formed from the oscillator 14 and the coils 11 being shown schematically.
  • the electrical current I induced in the coils 10 is tapped via electrical lines 16 and fed via a rectifier 17 to a capacitor 18 which serves as a store for the electrical energy emitted by the generator.
  • a capacitor 18 which serves as a store for the electrical energy emitted by the generator.
  • a rechargeable battery 19 instead of a capacitor, a rechargeable battery 19 has been used as the electrical energy store, a charger 20 being connected upstream of the battery 19.
