Definitions

  • the invention relates to a steering wheel.
  • inertial masses to compensate vibrations, by which the resonance frequency of the steering wheel is shifted into a non-critical range.
  • These inertial masses can either be additional masses or suitably arranged components of, for example, gas bag restraint systems, in particular the gas generator. If additional masses are used, this leads to additional costs and to an increased weight. If components of the gas bag restraint system are used, various problems arise, such as the gas tightness of the gas generators or the transmission of reaction forces on activation of the gas bag.
  • the object of the invention consists in achieving a neutralizing of vibrations of the steering wheel with a small expenditure.
  • a steering wheel which comprises a rim skeleton and a rim casing, at least one vibration-damping element being provided which is arranged between the rim skeleton and the rim casing.
  • the invention is based on the fundamental idea of neutralizing in terms of vibration technology only that part of the steering wheel for which this is absolutely necessary. This is the rim casing which comes into contact with the hands of the driver of the vehicle concerned. If the rim casing is neutralized in terms of vibration technology, vibrations of the remaining parts of the steering wheel, for example the steering wheel hub or the steering wheel spokes, are scarcely noticed.
  • a further advantage of the construction according to the invention consists in that through the neutralizing merely of the rim casing, only a smaller vibrating mass has to be neutralized.
  • FIG. 1 shows a steering wheel in a diagrammatic view
  • FIG. 2 shows in a sectional view a steering wheel according to a first embodiment of the invention.
  • FIG. 3 shows in a sectional view a steering wheel according to a second embodiment of the invention.
  • FIG. 1 a steering wheel is illustrated diagrammatically. It contains a steering wheel hub 10 , several spokes 12 and a rim skeleton 14 . On the rim skeleton 14 a rim casing 16 is arranged, which is grasped by the driver of a vehicle equipped with the steering wheel.
  • FIG. 2 a cross-section is shown through the rim skeleton and the rim casing of a steering wheel according to a first embodiment.
  • the rim skeleton 14 is constructed here with a U-shaped cross-section which is completely surrounded by a vibration-damping element 20 , 22 .
  • the vibration-damping element consists of a vibration-damping material, preferably of polyurethane foam, and is constructed in two parts, namely with an upper part 20 and a lower part 22 .
  • the upper part 20 and the lower part 22 together produce a circular cross-section.
  • the rim casing 16 On the vibration-damping element 20 , 22 the rim casing 16 is arranged, which consists of a shell having an annular cross-section and is foamed onto the vibration-damping element. Owing to the elastic characteristics of the vibration-damping element 20 , 22 , the rim casing 16 is mounted on the rim skeleton 14 in a vibration-free manner or at least in a damped manner with respect to vibrations.
  • FIG. 3 a section is shown through a steering wheel according to a second embodiment.
  • several rings 20 are used as vibration-damping element, which in contrast to the continuous insert known from the first embodiment are arranged spaced apart from each other, and which locally support the rim casing. Between the vibration-damping rings 20 there is a free space between the rim skeleton 14 and the rim casing 16 .
  • the rim casing 16 consists of an upper shell and a lower shell which are placed onto the vibration-damping rings and are connected with each other to form the rim casing.
