Definitions

  • the invention relates to a vibration damper according to the preamble of claim 1 and the preamble of claim 11.
  • Such vibration absorbers are used in motor vehicles and commercial vehicles in order to absorb vibrations in the area of the steering wheel and to counteract them.
  • the vibrations that occur in these vehicles while driving or at a standstill with the engine running can be transferred to the steering column and from there to the steering wheel.
  • vibration absorbers can be attached either directly to the steering column or in the steering wheel below an airbag module located there.
  • Steering wheels are also known which incorporate the airbag module or the gas generator as an oscillating mass for the vibration damper.
  • Hitherto known vibration absorbers for example described in DE 102004 038023 B4, have at least one spring element made of an elastomeric material, on which further attachment elements, for example a receiving flange and / or a fastening flange, are each made of a different material than the spring element, for example made of a metal rule alloy, chemically bonded and / or form-fitting vulcanized, these formations being produced in a vulcanization tool.
  • Previously known Vibration absorbers are usually connected to the mounting flange via a first connection made by vulcanization to support the gas generator, and connected to a fastening flange via a second connection made by vulcanization in order to be attached to a module base of the steering wheel and / or aligned during installation become. Therefore, previously known add-on elements and spring elements are inseparable material and / o positively connected to one another and, although possibly different materia lien, form a one-piece element.
  • vibration absorbers are complex to manufacture, however, since the degree of automation is low because the add-on elements have to be manually inserted into the corresponding tool for vulcanization.
  • add-on elements and possibly also the spring elements of previously known vibration absorbers have complex geometries, since they must have fixing points such as holes and undercuts for a permanent hold.
  • the add-on elements must also be manufactured very precisely and therefore have small dimensional tolerance limits in order to prevent incorrect vulcanization due to undesired material flow.
  • the add-on elements must be positioned and sealed very precisely in the vulcanization tool for the same reason. Appropriate manufacturing tools are correspondingly complex and expensive.
  • the invention is therefore based on the object of creating a vibration damper which at least partially overcomes the disadvantages of the prior art, in particular is easier to manufacture and less complex in design, and enables an increased degree of automation in its manufacture.
  • a vibration damper for a motor vehicle steering wheel which can comprise a gas generator for a steering wheel airbag as an inertial mass, the vibration damper being a substantially hollow cylinder or hollow truncated cone-shaped spring element made of an elastomeric material which can be connected to the motor vehicle steering wheel and / or a motor vehicle steering wheel module, and a carrier ring connected to the spring element, which can be connected to the gas generator.
  • the spring element and the carrier ring are designed as separate components and / or the spring element is designed as a monolithic molded rubber part.
  • the carrier ring is at least not vulcanized onto the spring element, although both elements can form a first connection with one another.
  • the carrier ring can also dispense with form-fit holes, since there is no connection to the carrier ring when the spring element is molded in the vulcanization tool.
  • the spring element can form an assembly with the carrier ring.
  • Elements that consist of a single piece and are made of one piece are intended to be monolithic in the context of the invention. Elements that are produced individually and separately from one another are to be considered separate within the meaning of the invention. In the context of the invention, elements that are at least partially produced with one another, for example a vulcanized element, are to be regarded as one-piece.
  • the installation of the vibration damper in a steering wheel module should be understood as assembly.
  • the spring element comprises a substantially radially inwardly protruding inner flange which is designed to engage in a circumferentially extending outer ring groove of the carrier ring, the spring element and the carrier ring thereby forming a positive and / or non-positive and gas-tight first connection be able.
  • the formation of such a connection means that when the vibration damper is assembled, the inner flange simply snaps into the outer ring groove and is prepositioned there at least in the axial direction.
  • a great coverage of the inner flange and outer ring groove also means that a gas-tight connection can be achieved with simple means.
  • they can also interact in a labyrinthine manner, which increases gas tightness.
  • the spring element and the carrier ring form a crimp connection with one another.
  • axial forces can be applied to the outer ring groove in order to clamp the inner flange between the wall sections of the outer ring groove.
  • the inner flange comprises, at least in sections, a free edge that is thickened distally in relation to a main flange body.
  • the thickened free edge thus forms an undercut, in which the outer ring groove can engage after crimping and thus a loosening of the spring element and carrier ring can be reliably prevented. This connection withstands high stress even if the airbag is deployed.
  • the spring element has a radially outer clamping shoulder in the area of its first distal edge, which is designed such that it is unloaded in a pre-assembly state and can be compressed by a diffuser and / or another steering wheel component in an assembly state in order to be able to form a form-fitting and / or force-fitting connection via this.
  • the spring element can be clamped in a simple manner.
  • the vibration damper comprises a shaped ring which is arranged in the area of the first distal edge on the spring element.
  • the shaped ring can be selected from a material which is more rigid than that of the spring element.
  • the molded ring can be arranged inside the spring element, possibly clamped, in order to ensure dimensional stability of the spring element during assembly.
  • the molded ring can serve as a counter bearing for a diffuser and / or another steering wheel component if the clamping shoulder of the Federele element is compressed by it.
  • the shaped ring can be arranged on the inside of the spring element opposite the clamping shoulder or at least in this area.
  • the vibration damper according to the invention can be designed in such a way that the spring element forms a radially inner clamping cone in the area of its second distal edge, which is designed in such a way that it is unloaded in a preassembled state and force-loaded radially outward from the carrier ring in an assembled state - Can be hit and / or expanded.
  • the cross-sectional profile of the second distal edge can therefore be conical at least in sections in the axial direction, preferably thickening towards the end face. It is also conceivable that the clamping cone is designed to thicken the second distal edge, as a result of which a radially outer stop cushion is formed at least in the assembled state.
  • a radial distance between the vibration absorber and the surrounding element can be selected to be small, which means that not only the vibration absorber but also the steering wheel module can be made small.
  • steering wheels with a small steering wheel hub can be implemented, which increases the freedom of design.
  • the spring element can form an annular seal in the area of its first distal edge, which is designed such that it can be compressed against a module base and / or another steering wheel component in an assembled state in order to be able to form a gas-tight second connection.
  • the ring seal is designed monolithically with the spring element and is preferably designed in the axial direction so that it can be acted upon by force in the axial direction by a diffuser and / or another steering wheel component.
  • the carrier ring is designed and / or arranged in such a way that between its first distal edge, which can be turned towards a module base and / or another steering wheel component, and a module base and / or another steering wheel component stood in a Montagezu there is a support distance which can be zero when the airbag is triggered, so that an adjustment movement of a gas generator is limited.
  • the gas generator experiences an axially directed recoil.
  • the gas generator can be indirectly supported axially via the carrier ring against the module base and / or another steering wheel component. It can be advantageous to choose an acceleration distance the size of the support distance as small as possible but greater than zero in order to keep the speed as low as possible in the event of an impact against the module floor and / or against another steering wheel component and thus avoid damage.
