Definitions
- the invention relates to a filter housing of a brake dust particle filter for a brake disc arrangement according to the preamble of claim 1.
- Brake dust particle filters which can be attached to brake disc assemblies, can be used to capture brake dust caused by the friction between the brake disc and brake pad during a braking process.
- the brake dust particle filter has a filter housing in the shape of a segment of a circle with a filter material accommodated therein.
- the filter housing has two housing side walls spaced apart from one another, which in the installed state are arranged on opposite sides of the brake disc and delimit an intermediate receiving space for the brake disc.
- Such a brake dust particle filter is described, for example, in DE 10 2012 016 835 A1.
- the invention is based on the object of creating a stably constructed brake dust particle filter with simple structural measures, which has a lower tendency to excite vibrations, particularly in the assembled state.
- the filter housing of the brake dust particle filter according to the invention has a basic geometry in the form of a segment of a circle and is used to collect brake dust in a brake disc arrangement which is preferably used in motor vehicles.
- the filter housing has two housing side walls which are spaced apart from one another and at least partially delimit an intermediate receiving space into which the brake disk of the brake disk arrangement protrudes in the installed state.
- the two housing side walls preferably run parallel to one another and are connected on the radially outer side via an outer housing wall of the filter housing.
- both housing side walls and the radially outer housing wall are designed as a one-piece component.
- a multi-part design is also possible, in particular a two-part design with a left and a right housing side wall, with the housing outer wall being arranged divided on each housing side wall or completely connected to one of the housing side walls.
- a first housing side wall is composed of a housing base wall and a supporting bridge adjoining it in the circumferential direction.
- the second housing side wall preferably extends over a smaller angular segment than the first housing side wall.
- the first housing side wall consisting of the housing base wall and the supporting bridge, thus covers a larger angular segment than the second housing side wall.
- the second housing side wall extends over the same angular segment as the housing base wall of the first housing side wall and is directly opposite the housing base wall.
- the support bridge extends in the circumferential direction in particular beyond the receiving space.
- the receiving space extends axially between the housing base wall, the first housing side wall and the second housing side wall.
- This design has the advantage that the filter housing can be additionally fastened to the brake disc arrangement via the support bridge.
- a fastening can be carried out on opposite sides of the filter housing in the circumferential direction on the brake disk arrangement.
- the attachment is advantageously carried out on a brake caliper of the brake disc assembly. It is possible, for example, to carry out a first fastening on the free end face of the first or the second housing side wall and a further fastening on the opposite end in the circumferential direction, on the free end face of the supporting bridge.
- the filter housing of the brake dust particle filter can be connected to the brake caliper of the brake disk assembly.
- the filter housing can be designed with thinner walls without sacrificing stability.
- the flow conditions in the brake dust particle filter can be influenced using the support bridge. This applies in particular to the flow guidance of the air flow containing brake dust.
- both housing side walls can have a radial or tangential end face on a side facing the supporting bridge, with the supporting bridge adjoining the radial or tangential end face of the housing base wall.
- the radial or tangential end faces of the housing side walls are preferably connected by an end wall.
- the end wall can in turn have a receiving notch through which the brake disc extends in an assembled state.
- a part of the supporting bridge is arranged in the circumferential direction so that it overlaps the base wall of the housing.
- the base wall of the housing and the supporting bridge form separate components which, however, are advantageously firmly connected to one another.
- the supporting bridge is preferably located on the inside facing the receiving space, an arrangement with the supporting bridge on the outside of the housing base wall facing away from the interior also being possible.
- a circular The curved section of the supporting bridge can be moved along the housing base wall, which is also curved in a circular shape, until the desired final position is reached and fixed in this position. It can possibly be expedient for the supporting bridge to extend over a larger angular segment than the base wall of the housing.
- the supporting bridge can extend over an angular segment of at least 20°, preferably at least 40°.
- the base wall of the housing and the supporting bridge are designed as separate components which are, however, firmly connected to one another.
- the support bridge and the housing base wall can optionally also form a common, one-piece component.
- the transition from the peripheral end of the housing base wall to the support bridge can be clearly defined, for example in the form of a peripheral end face on the housing base wall. It is possible that the supporting bridge has a different cross-sectional shape compared to the housing base wall.
- the housing base wall of the first housing side wall and the second housing side wall are designed to be approximately or completely mirror-symmetrical to one another.
- the housing base wall and the second housing side wall are directly offset from one another in parallel and extend over the same angular segment.
- the supporting bridge which adjoins the housing base wall, protrudes in the circumferential direction beyond this angular segment and correspondingly widens the angular segment of the housing base wall.
- the housing base wall advantageously extends over a larger angular segment than the supporting bridge.
- the supporting bridge it is also possible for the supporting bridge to extend over an angular segment of the same size as the base wall of the housing, or over a larger angular segment.
- the base wall of the housing and the support bridge occupy an angular segment of at least 180°.
- the need for additional support of the filter housing by a supporting bridge is present above all in the case of filter housings of brake dust filters which extend over a comparatively large angular segment of the brake disk.
- the support bridge provided according to the invention is a surprisingly effective measure for significantly reducing the extent of vibration excitation.
- the problem of vibration excitation is also negatively influenced by the mass of the filter housing, so that the filter housing according to the invention is particularly suitable for brake dust particle filters that are provided for heavy commercial vehicles and/or rail vehicles.
- Such filter housings differ significantly from brake dust particle filter housings for use in passenger cars.
- the radially outer side of the support bridge is at least partially set back radially with respect to the outer radius of the housing base wall.
- the outside of the housing base wall preferably extends in a circular shape; Compared to this circular shape, the outside of the supporting bridge is set back radially, at least in sections.
- the receiving space which lies between the housing base wall and the second housing side wall, also serves to receive a filter material on which the brake dust is deposited.
- the part of the supporting bridge that protrudes beyond the base wall of the housing is advantageously free of filter material and is only used for additional fastening of the filter housing and, if necessary, for guiding the flow.
- the radially set-back outside of the supporting bridge has, for example, a rectilinear section, which can in particular run tangentially (with respect to a direction of rotation of the brake disk in the assembled state). It can be expedient for the outside of the supporting bridge to be composed of a first section bent in a circle and a second section formed in a straight line, with the section bent in a circle directly adjoining the circular base wall of the housing. This rectilinear second section of the support bridge can be designed in a triangular shape tapering to a point.
- the support bridge has an additional attachment point, via which attachment preferably takes place on the brake caliper of the brake disc arrangement. The attachment point is located in the peripheral end area of the supporting bridge facing away from the housing base wall, preferably in the area of a distal triangular tip.
- flow openings are made in the supporting bridge.
- the flow openings have a flow-influencing and flow-guiding function for the air flow in which the brake dust is entrained.
- Flow openings can also be made in the base wall of the housing, as well as in the second housing wall and in the connecting, radially outer housing wall. If necessary, the flow openings of the supporting bridge differ from the flow openings of the housing base wall.
- the flow openings in the housing base wall are designed, for example, in the form of slots and extend in the tangential direction.
- the flow openings in the support bridge can be rectangular or trapezoidal, optionally triangular.
- the invention also relates to a brake dust particle filter, which comprises a filter housing in the form of a segment of a circle as described above, including a support bridge.
- the brake dust particle filter also includes a filter material that is received in the receiving space that lies between the housing side walls and also receives the brake disc.
- the filter material can have a U-shaped cross-section that extends over the brake disk.
- Another aspect of the invention relates to a brake disc assembly-brake dust particle filter combination with a brake dust particle filter as described above and with a brake disc assembly, wherein the support bridge of the filter housing of the brake dust particle filter is attached to a brake caliper of the brake disc assembly.
- FIG. 1 shows a perspective view of a combination of brake disc assembly and brake dust particle filter, which has a filter housing with a support bridge on a housing side wall,
- FIG. 3 shows the filter housing of the brake dust particle filter in a perspective corresponding to FIG. 1,
- FIG. 4 shows the filter housing in a perspective corresponding to FIG. 2,
- FIG. 6 shows a representation corresponding to FIG. 5 in a side view
- FIG. 7 shows a representation corresponding to FIG. 5 or FIG. 6, but in a rear view.
- FIGS. 5 to 7 a combination 1 of a brake disc assembly 2 and a brake dust particle filter 3 supported and carried by the brake disc assembly 2 is shown.
- the brake disc assembly 2 is typically used in motor vehicles.
- the brake dust particle filter 3 absorbs the brake dust that is produced by abrasion of the brake pads when the brake disc arrangement 2 is actuated.
- the brake disc arrangement 2 comprises a brake caliper 5, which is a carrier of brake pads, which rest against the brake disc 4 during a braking process.
- the brake caliper 5 is mounted in a floating manner on a brake caliper holder which is fastened, for example, to a wheel carrier. The floating mounting of the brake caliper 5 allows the brake caliper to move relative to the brake caliper holder in the axial direction, based on the longitudinal axis of the brake disc 4.
- the brake dust particle filter 3 has a filter housing 6 in which a filter material is included, on which the brake dust is deposited.
- the filter housing 6, which is shown in detail in FIGS. 3 and 4, is constructed in the form of a segment of a circle and has two housing side walls 7 and 8 which are arranged parallel to one another and are spaced apart and which are connected via a curved outer housing wall 9 lying radially on the outside. Flow openings are introduced in both housing side walls 7, 8 and in the housing outer wall 9, through which air cleaned of brake dust can flow out.
- the housing side walls 7, 8 define between them a receiving space 10 for receiving the brake disc 4.
- the receiving space 10 has a U-shaped cross-section.
- the filter material that is inserted into the accommodating space 10 and collects the brake dust has a U-shaped cross-sectional shape, which allows the brake disc 4 to protrude into the accommodating space 10 .
- the first housing wall 7 is composed of a housing base wall 7a and a supporting bridge 11 adjoining the housing base wall 7a in the circumferential direction.
- the housing base wall 7a is essentially a mirror image of the second housing side wall 8; they extend over the same angular segment, which is between 100° and 120°.
- the housing base wall 7a and the supporting bridge 11 extend over an angular segment of 180°.
- the housing base wall 7a, the second housing wall 8 and the housing outer wall 9 form a one-piece component.
- the support bridge 11 is designed as a separate component.
- the support bridge 11 also has flow openings, which, however, differ in terms of their shape from the flow openings in the housing base wall 7a and in the second housing wall 8 .
- Flow openings in the housing base wall 7a and in the opposite, second housing side wall 8 are slot-shaped and extend in the tangential direction, whereas the flow openings in the supporting bridge 11 are rectangular, in particular trapezoidal and partially triangular.
- the flow openings in the housing outer wall 9 are also slot-shaped and extend in the axial direction, based on the longitudinal and rotational axis of the brake disc 4.
- the supporting bridge 11 extends over a larger angular segment than the housing base wall 7a.
- the support bridge 11 is designed separately from the housing base wall 7a and is located on the dem Receiving space 10 facing the inside of the housing base wall 7a.
- the support bridge 11 is composed of a total of three sections: an attachment section 11a located at a peripheral end, a curved section 11b, and a triangular section 11c having a straight outer side.
- the curved section 11b runs parallel to the housing base wall 7a, whereas the fastening section 11a and the triangular section 11c protrude from the housing base wall 7a on opposite sides.
- Both the fastening section 11a and the triangular section 11c are used for fastening to the brake caliper 5.
- fastening points are introduced into the fastening section 11a and into the outer tip of the triangular section 11c.
- the support bridge 11 thus makes it possible to connect the filter housing 6 to the brake caliper at two opposite points in the circumferential direction, as a result of which a connection with high stability is created.
- the triangular section 11c is beveled with the straight outside in such a way that this straight outside is set back radially with respect to the outer radius of the housing base wall 7a and the supporting bridge 11 .
- the support bridge 11 can be attached to either side of the filter housing 6.
- the supporting bridge 11 is located on the first housing side wall 7.
- An arrangement on the opposite, second housing side wall 8 is also possible.
- the supporting bridge 11 can be arranged both on the inside and on the outside of the housing walls.
