Definitions

  • the invention relates to a holder for fastening a component, in particular a fuel distributor, to an internal combustion engine and to a system which is preferably a fuel injection system or a part of a fuel injection system.
  • the invention relates to the field of fuel injection systems of internal combustion engines, wherein high pressure fuel is injected through fuel injectors into associated combustion chambers of the internal combustion engine.
  • the engine assembly includes a cylinder head, a cam cover, and a fuel rail assembly.
  • the fuel rail assembly includes the fuel rail, a bracket assembly, and a fuel injector.
  • the fuel rail of the engine assembly is attached to the cam cover.
  • the staple assembly is fixed to the fuel rail, comprising a fastener and an insulation element.
  • the fastener engages the cam cover and secures the fuel rail thereto.
  • the fastening assembly may comprise fastening elements, spacers and a sleeve as well as a first and a second insulating element.
  • the fasteners include a head and a stem with a threaded portion that engages an opening in the cam cover to secure the fuel rail to the cam cover.
  • the fastener extends through the sleeve.
  • the first isolation member is disposed axially between a first side of the bracket and the cam cover.
  • the second isolation member is disposed axially between the second side of the bracket and the head of the fastener.
  • the insulating elements may be formed of an elastomeric material which provides for damping.
  • the from the DE 10 2010 046 344 A1 known motor assembly has the disadvantage that are secured by the head of the fastener, which is screwed into the cam cover, via the spacer, the insulating elements of the elastomeric material.
  • the fastener both the attachment to the cam cover and the fixation of the insulation elements. Since the tightening torque of the fastener must be large, thus two possible cases with respect to a dimensioning of the spacer are possible. If the spacer designed slightly too short, then there is a game of the clip between the insulation elements, which significantly affects the function, so this case is to be avoided.
  • the spacer is designed to be too long, taking into account possible tolerances, then there is a high local compression of the insulation elements, which can not be avoided due to the required high tightening torque.
  • This high pressure then leads to a local component fatigue on the insulating elements, namely on the one hand in the region of the spacer and on the other hand on a stepped portion of a sleeve on which the first insulating element is supported.
  • the biasing member is configured as a thin-walled sleeve with an L-shaped profile.
  • a second thin-walled sleeve is provided with an L-shaped profile which acts as a support member, so that the decoupling element of the biasing member as well as the support member is biased, and so far until both sleeve members abut against each other.
  • the two sleeve elements serve as compression limiters, which ensure that a desired compression of the decoupling elements is not exceeded.

Specifically, with respect to the particular application, a suitable adaptation of the vibration damping can be made.

  • the connection between the biasing member and the fixing body can be suitably configured. After the connection is configured, then the mounting force can be reduced again.
  • the tightening torque for the fastening means or a fastening force generated by the fastening means for fastening the fastening body to the internal combustion engine is independent of the mounting force for biasing the decoupling element. This is because the fastening means and the fastening body lie in a force path which is independent of a force path in which the biasing element, the decoupling element and the fastening body lie. The traction takes place here only both times on the mounting body.
  • the system is preferably designed as a fuel injection system or part of a fuel injection system.

  • it is also possible to dynamically tune a frequency-dependent stiffness profile as well as a frequency-dependent attenuation by means of the adjustability via the pretension and optionally the geometry of the decoupling element. This results in an adjustable or tunable transfer function.
  • the acoustic behavior of the system in particular the fuel injection system, can be improved. Furthermore, the stress on the components used by the assembly and by operating temperatures can be reduced.
