DETAILED DESCRIPTION OF THE INVENTION

Considering the numbering adopted in the figures, the filter for a brake device F comprises a case1,1′ made of sheet metal, a cylindrical tubular filtering element2and a dismantlable axial fastening system which allows the filter assembly of the present disclosure to first be assembled in the brake device F and dismantled; second it provides axial fastening of the filter when same is assembled on the filter device; and third it provides axial fastening of the filtering element2.

The filtering element2is located and fitted inside the case1,1′, wherein the case1,1′ includes at least one cylindrical tubular lateral wall3having two opposite end edges, a first and a second. The filtering element2sits on an internal surface of the lateral wall3of the case1,1′. Said lateral wall3of the case1,1′ includes a set of holes4.

Once the filter of the present disclosure is assembled around the brake device F, the latter is encapsulated within an inner space of the filter, wherein said inner space is radially delimited by the filtering element2having a cylindrical tubular configuration. The filtering element2is configured for retaining contaminating particles that are released from the brake device F housed inside the inner space delimited by the filtering element2, such as for example the brake device described in present disclosure patent ES2705358, wherein said brake device externally includes protrusions fitting into axial channels5located in the filtering element2.

In a first embodiment of the present disclosure shown inFIGS.1to3, the cylindrical tubular case1is a whole body and includes an annular bottom6in the form of a washer which is integrally attached to the first end edge of the lateral wall3forming part of the case1itself, whereas a support ring7is coupled in a dismantlable manner to the second end edge of the case1.

To that end, the support ring7includes an annular groove8in which the second end edge of the case1fits. Furthermore, to secure the fastening of the support ring7on the case1, engagement mechanisms9are included, each of which comprises a pivoting blade9a, an articulated frame9bconnected in an articulated manner to the pivoting blade9a, and a fixed flange9con which the articulated frame9bengages in an anchoring position of the engagement mechanism9.

Each pivoting blade9ais coupled in an articulated manner to a protruding appendage integral with the support ring7, whereas the fixed flange is integral with the case1.

In this first embodiment of the present disclosure being described, the dismantlable axial fastening system of the filter assembly is formed by the annular bottom6of the case1and by the support ring7, wherein both the annular bottom6and the support ring7include through holes10,11aligned with the axial channels5of the filtering element2.

In a second embodiment of the present disclosure shown inFIG.4, the case1′ comprises two parts which are attached by means of a hinged articulation12, while at the same time including engagement mechanisms9′ such as those described above for being able to engage between one another the two parts of said case1′ and being able to stably put together the structure of the cylindrical tubular case1′. Said engagement mechanisms9′ are located in proximity to facing edges of the two parts of the case1′.

In this second embodiment of the present disclosure, the filtering element2comprises two separate parts that are joined together when the filter is assembled around the brake device F, wherein in said assembled position the filtering element2forms a cylindrical tubular shape equivalent to that described in the first embodiment.

In the second embodiment of the present disclosure, there are furthermore included two opposing support rings7′ constituting the dismantlable axial fastening system of the filter when same is assembled in the brake device F. To that end, the support rings7′ are placed in parallel planes inside the case1′ in contact with the internal surface of the case1′, wherein said contact is close to the two opposite end edges: first and second of the case1′. The support rings7′ include through holes13,14aligned with the axial channels5of the filtering element2.

Moreover, both the support ring7of the first embodiment and one of the support rings7′ of the second embodiment of the present disclosure include pairs of boreholes15which are configured for sleeves16to be fitted therein for connecting to cooling conduits of the brake device described in patent ES2705358, which belongs to the same proprietor as the present disclosure.

Therefore, the assembly of the case1,1′ made of drilled sheet metal together with the filtering element (2) surrounds the brake device F, such that all the particles that are released in each braking are deposited in said filtering element2, preventing them from being released into the air.

When the filter has been used for a certain number of kilometres, a first option includes the filtering element2being replaced with another new one and being able to recycle the used filtering element2; and a second option includes being able to use the filtering element again if it is washable. In this situation, the brake device of the mentioned patent is once again in conditions where it can continue braking and protecting the environment.

The protection of the present disclosure also extends to “soundproofing” with respect to the noise generated by the brake device in each braking, and to the “protection of the brake device against external agents”, such as dust, sand, small stones, etc.

In the design of the encapsulation of the brake device of the referenced patent, the easy replacement of the filter has been taken into account, where once the wheel of a vehicle has been removed, it leaves the encapsulation of the case1,1′ in view, in such a way that by actuating the engagement mechanisms9,9′ by hand, the case1,1′ is released and can be manually removed outwards, leaving the particle filtering element2in view, which in turn, by extracting it also outwards, allows its easy replacement, proceeding by the same method for its assembly.

The figures show descriptive but non-limiting examples of the encapsulation system mainly applicable to the brake device of the referenced patent ES2705358, and its design variants for the easy replacement of the particle filtering element2, also depending on the positioning arrangement of said brake device; it should also be noted that the filtering of harmful particles is 100%.

It is important to understand that the brake device of the referenced patent has the technical capability to be installed both on the wheel (non-suspended) and on the vehicle chassis (suspended). The first embodiment of the present disclosure would be appropriate for being installed on the wheel of a vehicle, whereas the second embodiment of the present disclosure could be installed both ways.
