Definitions

  • the invention relates to the removal of brake dust of a vehicle brake.
  • Friction brakes which are commonly used in motor vehicles, release brake dust during their operation due to the brake wear. Since the brakes of motor vehicles are usually open, the brake dust u.a. emitted as particulate matter into the environment, thus leading to environmental pollution and health impacts. Furthermore, the brake dust causes heavy contamination on the vehicle, in particular on the vehicle rim, from where it is difficult to remove. Because of the high temperature of the heated by the friction dust burns this in the surface of the rim.

  • the system according to the invention serves to remove brake dust from a brake of a vehicle.
  • the vehicle has an exhaust pipe for transporting combustion gases of an internal combustion engine.
  • the system according to the invention comprises a line for transporting the brake dust from the brake to the exhaust pipe.
  • the line is connected to the exhaust pipe such that the brake dust is sucked from the line into the exhaust pipe.
  • the exhaust pipe is primarily used for the transport of combustion gases emitted by the internal combustion engine in the direction of the exhaust of the vehicle, and of any existing entrained by the combustion gases particles. If appropriate, the exhaust gas line may have different components or run over different components, for example via one or more particle filters and / or a catalyst.
  • the exhaust pipe is used in addition to the transport of brake dust. This has the advantage that the brake dust can be disposed of or expelled in the same way as the combustion gases or possibly entrained by the combustion gases particles.
  • a transport takes place through a line from the brake to the exhaust pipe.
  • the line can pick up and carry away the brake dust generated by the brake directly from the brake or from the vicinity of the brake, or from a device arranged on the brake or in the vicinity of the brake.
  • the conduit is preferably arranged with respect to the brake such that the brake dust is almost completely removed by the conduit. Alternatively, it is possible that the line carries only a certain part of the brake dust.
  • the brake dust is sucked from the pipe into the exhaust pipe. After the brake dust has reached the exhaust pipe, it is entrained by the combustion gases.
  • Brake dust therefore moves in the exhaust pipe in the stream of combustion gases.
  • a mechanism for transporting the brake dust within the exhaust pipe, besides the flow of the combustion gases, is therefore unnecessary.
  • the suction of the brake dust in the exhaust pipe can be effected for example by a pump arranged in the exhaust pipe.
  • the line is connected to the Ab- Gas line is connected so that the brake dust is sucked from the line into the exhaust pipe due to the Venturi principle.
  • the mechanism of suction is based solely on the venturi principle; a responsible for the suction device such as a pump is not necessary.
  • the mechanism of suction is based on both the Venturi principle and on a suction device. To exploit the Venturi principle, it makes sense to let the line run partially coaxially within the exhaust pipe.
  • a device for collecting brake dust located in the vicinity of the brake is provided in the line before being transported. If the brake includes a brake disc and at least one brake pad, the

  • a filter in the exhaust pipe is present, through which at least a portion of the brake dust is filtered out.
  • This may be e.g. to act a diesel particulate filter.
  • the filtering makes it possible to eliminate the filtered-out part of the brake dust in the same way as the particles of the combustion gases trapped by the filter, e.g. by burning.
  • the use of a filter is advantageous because it can avoid the emission of at least part of the brake dust.

  • the method according to the invention serves to remove brake dust from a brake of a vehicle, the vehicle having an exhaust pipe for transporting combustion gases of an internal combustion engine.
  • the brake dust is transported in a line from the brake to the exhaust pipe in such a way that the brake dust is sucked from the line into the exhaust pipe.
  • inventive method is particularly suitable for the inventive system, and this may also apply to the embodiments and developments. For this purpose it may comprise further suitable steps.
  • Figure 1 a system for removing brake dust.
  • FIG. 1 shows the brake disk 0 with the brake 1 of the vehicle.
  • the direction of rotation of the brake disc 0 is indicated by an arrow.
  • a brake dust collector 2 On the brake disc is a brake dust collector 2, which collects the brake dust generated by the brake 1.
  • the brake dust is created by abrasion of a brake disc.
  • brake dust collector 2 The exact operation of the brake dust collector 2 is not relevant to the understanding of the system; In principle, various collection mechanisms can be used. Examples of brake dust collectors are e.g. in the documents DE 198 46 887 Al and DE 103 36 984 Al explained.
  • the suction line 3 transports the brake dust away from the brake dust collector 2, wherein the brake dust is introduced into the line 4.
  • the line 4 is a part of the exhaust tract of the vehicle, which follows the engine VM. The line 4 thus transports the combustion gases from the engine VM to an exhaust not shown in Figure 1.
  • Venturi nozzles consist of a tube with a constriction. When such a nozzle is traversed by a liquid or a gas, its pressure changes according to the law of Bernoulli: at the narrowed point, the pressure is reduced relative to the wide spots. Such a pressure reduction is generated in the conduit 4, characterized in that the suction line 3 reduces the available cross-section of the engine gases in the conduit 4.
  • the suction line 3 preferably runs coaxially to the line 4 at its end. This allows a particularly advantageous exit of the brake dust from the suction line 3 into the line 4.
  • other arrangements are also possible.
  • the filter F may in particular be a diesel particulate filter or particulate filter, thus a means for reducing existing in the exhaust of diesel engines particles.
  • the brake dust remains in the filter F and is not excreted through the exhaust. The remaining in the filter F brake dust can be burned together with other particles in a known manner.
  • the system described allows efficient removal of brake dust. This will cause both the rims and the brake, e.g. Cylinders, guides and mechanics, not or only slightly soiled by brake dust. If a filter is used, there is no emission of the brake dust into the environment.
  • Another advantage of the system shown in FIG. 1 is that an already existing gas flow is used to remove the brake dust. It is therefore not necessary to use a separate pump. This saves both energy and space. Furthermore, it is advantageous that an air flow is generated by the removal of the brake dust through the suction line 3, which causes a cooling of the brake disc 0.
  • the brake dust is introduced into the exhaust tract.
  • An alternative solution to this would be the introduction of the brake dust in the intake. Since negative pressure generally prevails in the intake tract, aspiration of the brake dust in this case would be more efficient.
  • this procedure would have the disadvantage that the internal combustion engine VM could be damaged by the brake dust or limited in its efficiency.
  • a further filter would have to be inserted in addition to the air filter of the intake tract, since the air filter can not cause any filtering of these particles.
