Definitions

  • the invention relates to a device for vibration damping of functional components of a drive system of a vehicle, and to a fuel cell system which is mounted in a vibration- damped manner in a vehicle.
  • DE 100 53 849 A1 discloses a fuel cell installation for a vehicle which comprises a fuel cell module and/or a fuel cell stack which is decoupled mechanically from the vehicle on which it is mounted.
  • the fuel cell module is positioned on the undercarriage of a motor vehicle by means of a plurality of damping elements.
  • the damping system is of only single-stage construction and the four damping elements or the plurality of damping elements are connected virtually in parallel and arranged in one damping plane.
  • Vibration decoupling and thus the transmission of structure-borne noise can in this way be achieved only very inadequately, whereby the conditions for reduced transmission of structure-borne noise are very inadequate. Ride comfort is thereby reduced relatively severely.
  • a device according to the invention for vibration damping of functional components of a drive system of a vehicle is such that a functional component is mounted on a component carrier by at least one damping element and the component carrier is mounted on the vehicle body by at least one damping element.
  • the basic configuration of the device according to the invention is thus such that a functional component is mounted by a multistage damping system, in which the damping elements are primarily arranged not in a parallel functionality to one another but rather virtually in series.
  • Such a design of the device for vibration damping allows the transmission of structure- borne noise from the functional component and/or the component carrier to be substantially reduced.
  • the two damping elements are tuned to one another in their transmission behavior. This allows further improvement of vibration-related decoupling.
  • At least two functional components are mounted in a vibration-damped manner on the component carrier using in each case at least one damping element.
  • a module may thus be provided by the component carrier and the at least two functional components which may then itself in turn be mounted in a vibration-damped manner on the vehicle body.
  • parts which are combined into a module may themselves be mounted separately in a vibration-damped manner and the module as a whole may then in turn be mounted in a vibration-damped manner.
  • Such hierarchical, cascaded damping by means of the plurality of damping elements enables a particularly preferred reduction in structure-borne noise transmission, whereby optimum noise decoupling may be achieved by multiple impedance jumps.
  • the at least one functional component and the component carrier take the form of a module, this being mounted on the vehicle body by means of at least one damping element.
  • the functional component and a component carrier may thus also constitute a specially designed module, in which cascaded mounting of the damping elements leads to an improvement in transmission behavior.
  • Multiply decoupled suspension of components in the vehicle thus results in the possibility of improving optimum damping tuning of the cascaded damping elements with regard to their transmission behavior, whereby optimum noise decoupling may be achieved.
  • Excitation of neighboring components, connecting lines or elements of the supporting structure, which could in turn emit structure-borne noise, is thereby likewise largely prevented.
  • Multiple decoupling may be made possible by combining a plurality of components into modules, whereby double decoupling may be achieved, and by combining a plurality of modules in a common supporting structure, whereby triple and multiple decoupling may be achieved, the components in the module, the modules in the common supporting structure and the latter in turn in the vehicle being in each case mounted in the damping elements.
  • the drive system is a fuel cell system.
  • the individual functional components may thus be positioned in a particularly vibration- decoupled manner, whereby functional behavior and also wear may be reduced.
  • the effect on a vehicle user may thus also be reduced, whereby the noise behavior and the vibration behavior, which may affect the vehicle user, may be reduced at least significantly.
  • a functional component is a fuel cell stack or a blower or an element for modifying the flow cross-section of a line for operating media of the fuel cell or a receptacle for an operating medium of a fuel cell.
  • a functional component may for example also be a pump, for example an expander or a turbine, or indeed also a valve, a throttle valve or the like.
  • a damping element is made at least partially of an elastomer.
  • a very simple damping element may be obtained, which is however very advantageous with regard to damping.
  • a fuel cell system according to the invention is mounted by means of a device according to the invention or an advantageous development thereof on a vehicle body in a vibration- damped manner. Precisely such a specified drive system may thereby be better positioned in such a way that the transmission of structure-borne noise may be minimized.
  • An exemplary embodiment of the invention is explained in greater detail below with reference to a schematic drawing.
  • the single figure is a schematic side view of a device 1 for the vibration damping of functional components of a fuel cell system 5 of a vehicle.
  • the fuel cell system 5 takes the form of a mobile fuel cell system and comprises a plurality of fuel cells, which form a fuel cell stack.
  • the fuel cells may in particular take the form of PEM (Proton exchange membrane) fuel cells.
  • the fuel cell system 5 comprises a first functional component 2 and a second functional component 3.
  • Functional components are taken to be those parts of the fuel cell system 5 whose primary function consists in contributing to operation of the fuel cell system 5 and thus enabling drive.
  • the functional components 2 and 3 may therefore for example be a fuel cell stack, a blower, a pump, a valve or the like.
  • a functional component 2 and 3 is thus intended, depending on its primary function, to store, process or convey operating media.
  • connection 4 which may for example be a line system.
  • the first functional component 2 is mounted by means of two damping elements 6 and 7 in a vibration-damped manner on a component carrier 8.
  • the functional component 2 is connected to the component carrier 8 solely by means of these two damping elements 6 and 7.
  • the second functional component 3 is mounted on the component carrier 8 in a vibration-damped manner by means of two damping elements 9 and 10.
  • the component carrier 8 is in turn mounted in a vibration-damped manner on a module carrier 13 by two further damping elements 11 and 12.
  • the two functional components 2 and 3 and the component carrier 8 form a module 14, wherein the damping elements 6, 7, 9 and 10 and the connection 4 shown by way of example may in this context also be assigned to the module 14.
  • the module carrier 13 comprises on two opposing sides bearing brackets 15 and 16, via which the module carrier 13 is mounted on the vehicle body 19 in a vibration-damped manner by means of further damping elements 17 and 18.
  • the fuel cell system 5 is thus mounted in a vibration-damped manner on the vehicle body 19 by the device 1.
  • the functional components 2 and 3 as well as the component carrier 8 and also the module carrier 13 are mounted in a vibration-damped manner by a staged or cascaded damping system.
  • the cascaded configuration of the damping system is brought about by various damping planes, a first damping plane being formed by the damping elements 6, 7, 9 and 10.
  • a second damping plane is formed by the damping elements 11 and 12, whilst a third damping plane is formed by the damping elements 17 and 18.
