Definitions
- the present invention relates to the use of a carbon composite material for producing electrical contact bodies of a fuel pump operated in a fuel environment, the carbon composite material having, in addition to the carbon, a thermosetting or thermoplastic binder and a metal content greater than 0.5% and less than 25 % of the total mass of the carbon composite material.
- EP 1 713 148 A1 discloses a process for the production of carbon brushes, in which a pulverulent mixture of a carbon powder and a thermoplastic binder Metal powder is added and the powder mixture is processed in a compression molding process to form a carbon body.
- metal powders are added to the carbon in order to reduce the material resistance of the carbon brush and the contact resistance between the carbon brush and the commutator in the region of low stresses.
- the addition of a metal powder is recommended in a proportion of 30 to 60 wt -.%.
- brushless fuel pumps Because of their operation in a fuel environment, brushless fuel pumps have special operating conditions for the carbon brushes and commutator segments cooperating with the carbon brushes, which are not comparable to operating conditions outside the fuel environment. In particular, it has been found that in this fuel environment, temporary overvoltages exceeding 14V can significantly shorten the life of the brush-commutator systems as brush and commutator wear increases significantly due to overvoltages.
- the object of the present invention is therefore to reduce the wear of a brush-commutator system of a fuel pump operated in a fuel environment.
- This object is achieved by the use of a carbon composite material for the production of carbon contact bodies designed as electrical contact bodies having the features of claim 1.
- a carbon composite material for the production of carbon contact bodies designed as electrical contact bodies having the features of claim 1.
- a carbon composite as a solution to the above problem has been found, which in addition to the carbon and a thermosetting or thermoplastic binder has a metal content that is greater than 0.5% and less than 25% of the total mass of the carbon composite material.
- the inventive use of the carbon composite material proves to be particularly advantageous if the fuel pump is connected to an automotive on-board network with a mains voltage of 12 V.
- the metal content When the metal content is added to the carbon composite material in powder form, a particularly homogeneous distribution of the metal content in the carbon composite material can be achieved. It is particularly advantageous if the metal component predominantly has metal particles with a particle diameter of up to 1 mm, wherein particularly when 80% or particularly preferably 95% of the metal particles have a particle diameter of up to 1 mm, a particularly uniform wear can be achieved.
- the metal content comprises at least one metal of the metals comprising aluminum, zinc and silver metals.
- the metal content of aluminum or an aluminum alloy it is particularly advantageous if the metal content is greater than 0.5% and less than 20% of the total mass of the carbon composite material.
- the metal content of aluminum or an aluminum alloy is at most 10% of the total mass of the carbon composite material.
- the metal content of zinc or a zinc alloy it is particularly advantageous if the metal content is greater than 0.5% and less than 20% of the total mass of the carbon composite material.
- the metal content of zinc or a zinc alloy is at most 10% of the total mass of the carbon composite material.
- the metal content is greater than 0.5% and less than 15% of the total mass of the carbon composite material.
- the metal content of silver or a silver alloy is not more than 10% of the total mass of the carbon composite material.
- the metal part comprises several metals
- the metal part can be added as an alloy or as a mixture to the carbon material.
- the present task is also solved by the use of a contact body for forming an electrical contact on a fuel pump, wherein the contact body is formed as a carbon molded body of a carbon composite material, according to one or more of claims 1 to 16.
- the contact body used according to the invention is preferably designed as a carbon brush or as a commutator segment of a commutator.
- the fuel pump according to the invention has at least one carbon brush or a commutator segment, which is made of a carbon composite material according to one or more of claims 1 to 16.
- the material used to make a carbon brush includes:
- the material used for producing a carbon brush based on the total mass of the carbon composite material, comprises:
- thermosetting binder 7% thermosetting binder
- the material used for producing a carbon brush based on the total mass of the carbon composite material, comprises:
- the material used for producing a carbon brush, relative to the total mass of the carbon composite material comprises:
- thermosetting binder 7% thermosetting binder
- the material used for producing a commutator segment contains, based on the total mass of the carbon composite material: 10% thermoplastic binder,
- the material used to make a commutator segment based on the total mass of the carbon composite material includes:
- thermosetting binder - 10% thermosetting binder
- the material used to make a commutator segment based on the total mass of the carbon composite material comprises: 10% thermoplastic binder,
- the material used to make a commutator segment based on the total mass of the carbon composite material includes:
- thermosetting binder - 1 1% thermosetting binder
