Definitions
- the present invention relates to a system for capturing braking particles from a friction braking system, which comprises a source of depression, a pneumatic circuit which connects said friction braking system to the atmosphere, the source of depression being located on the pneumatic circuit, and a particle filtration system which is located on the pneumatic circuit and which comprises a filter which in operation becomes clogged by the particles preferentially on the surface.
- Such friction braking systems can be fitted to road or rail vehicles. Such friction braking systems can also be fitted to stationary rotor machines such as wind turbines or industrial machines.
- a source of depression for example a suction turbine driven by a motor
- a filter for collecting particles which are emitted by the braking system.
- the pneumatic circuit continues downstream of the source of depression and leads to the atmosphere.
- This filter is placed upstream of the source of depression, and prevents the passage of particles through the source of depression and their diffusion into the atmosphere.
- This filter can also be placed downstream of the source of depression, in which case it also prevents the diffusion of particles into the atmosphere.
- Such a filter collects particles throughout its volume (that is to say over its entire thickness).
- the pressure drop of these filters increases as the deposition in depth and on the surface of particles and dust.
- the present invention aims to remedy these drawbacks.
- the invention aims to provide a system for capturing braking particles from a friction braking system, the filter of which has optimized efficiency and lifetime.
- the capture system further comprises a storage container which is capable of receiving the particles which detach from the filter.
- the particles stopped by the filter are regularly stored in a separate zone of the filter.
- the filter regularly undergoes unclogging, and retains its filtration capacity.
- the maintenance of the filter is also facilitated since the evacuation of the particles is carried out by regular emptying of the storage container.
- the capture system also contains a device for unclogging the filter capable of causing the particles to fall into the storage container.
- the particles are regularly detached from the filter, which makes it possible to extend the life of the filter, and therefore of the capture system.
- this unclogging device is a vibrator which is capable of causing the filter to vibrate.
- this unclogging device comprises an air flow generator which passes through the filter.
- this generator is the source of depression.
- the storage container and the support form a closed space.
- the storage container is removable with respect to the support.
- the storage container can be emptied of the particles which have accumulated there, then reassembled with the support.
- the filter extends mainly along a plane P which is horizontal.
- the filter extends mainly along a plane P which presents with a horizontal plane H a non-zero angle [3 which is less than or equal to 90°.
- the storage container comprises a closing mechanism which makes it possible to avoid contact of the particles with an outside operator.
- the vacuum source is located on the part of the duct which connects the braking system to the filtration system.
- Figure 1 is a schematic view of a capture system according to the invention.
- Figure 2 is a perspective view of the capture system, showing the filtration system and the storage system assembled.
- Figure 3 is a perspective view of the capture system, showing the filtration system and the storage system disassembled.
- Figure 4 is a perspective view of the capture system according to another embodiment.
- Figure 5 is a schematic view of another embodiment of the capture system according to the invention.
- Figure 6 is a schematic view of yet another embodiment of the capture system according to the invention.
- Figure 1 schematically shows a particle capture system 1 according to the invention, these particles being emitted by a friction braking system 10.
- This friction braking system 10 includes a brake pad 11 for braking a vehicle.
- This plate 11 comprises a sole 12 and a lining 13 made of friction material fixed to the sole 12. In FIG. 1, the plate 10 is seen from below, the sole 1 being in the foreground.
- the wafer 11 (first wafer) faces a disk 9 which is driven by the wheel of the vehicle or of a machine.
- a second identical plate (not visible) is located on the other side of the disc 9 and facing the first plate 11 so that these two pads sandwich the disc 9.
- the braking of the disc 9 is achieved by friction of the two linings (13) against disc 9 when these two pads approach disc 9.
- the capture system 1 comprises a pneumatic circuit 30 and a vacuum source 20.
- the wafer 11 and the second wafer are connected to the vacuum source 20 via this pneumatic circuit 30.
- the vacuum source 20 comprises a electric motor 21 and a suction turbine 22 which is driven by this electric motor 21.
- the pneumatic circuit 30 therefore extends from the friction braking system 10 to the source of depression 20 and then continues downstream of the source depression 20 and leads to the atmosphere (outside).
- the vacuum source 20 is capable of sucking up the particles from their emission by the fittings (13) and through the pneumatic circuit 30.
- the direction of circulation of the air and the particles in normal operation is indicated by the arrow F in Figure 1.
- the arrow F therefore indicates a flow from upstream to downstream.
- the capture system further comprises filtration system 40 which comprises a support 41 and a filter 42.
- This filtration system 40 is located on the circuit 30, that is to say that the filter 42 is crossed by the air which circulates in the circuit 30.
- This filter 42 is mounted on the support 41 which is fixed in a sealed manner on the conduit 30, so that the support 41 forms an open space only upstream and downstream on the circuit 30, and on the storage container 50, described below. Thus, the particles tend to stay in this space.
- the filtration system 40 is advantageously located upstream of the source of depression 20 in order to prevent as much as possible the particles from passing through the source of depression 20.
- This variant is represented in FIG. 1.
- the filtration system 40 is located downstream of the source of depression 20 on the conduit 30, that is to say that the source of depression 20 is located on the part of the conduit 30 which connects the braking system 10 to the filtration system 40.
- Figure 6 This variant is shown in Figure 6.
- FIGs 2 and 3 are perspective views of the capture system, showing the filtration system 40 and the storage system 50.
- the filtration system 40 and the storage system 50 are shown assembled together.
- the filtration system 40 and the storage system 50 are shown disassembled.
- the support 41 is a box in which the filter 42 is housed.
- the filter 42 separates the box 41 into an upstream part and a downstream part.
- the air coming from the upstream part of the circuit 30 enters the box 41 through an inlet 411 at the level of the upstream part of the box 41 .
- the air passes through the filter 42, and leaves the box 41 at the level of the downstream part of the box 41 through an outlet orifice 412 to enter the downstream part of the circuit 30.
- the two orifices (411, 412) are located on the same face of the box 41. Alternatively these two orifices (411, 412) are each located on an opposite face of the box 41.
- the capture system 1 further comprises a storage container 50.
- This storage container 50 is secured to the support 41, and is intended to receive and store the particles which detach from the filter 42.
- the support 41 is a box, and the box 41 and the storage container 50 form a closed space (with the exception of the inlet and outlet orifices (411, 412)).
- the junction between the box 41 (or more generally the support 41) and the storage container 50 is sealed (for example using a seal) in order to prevent the particles from escaping.
- the storage container 50 is removable from the box 41. Thus, this container 50 can be emptied easily and then be secured again with the box 41. During emptying, the storage container 50 is advantageously provided with a cover (see below). In Figure 3, the container 50 is shown detached from the housing 41. In Figure 2, the container 50 is shown secured to the box 41. The storage container 50 can alternatively form a single assembly with the box 41 . In both cases, the storage container 50 may have an emptying orifice 55 (visible in dotted lines in FIGS. 2 and 3) which is closed in operation, and which can be opened in order to empty the container 50 of the particles. This drain orifice 55 is for example on the inner face (along the vertical axis A) of the box 50.
- the filter 42 has a lower face 426, an upper face 427, and a side edge which joins these two faces.
- the terms "lower” and “upper” are defined with respect to the vertical (vertical axis A) in operation.
- a horizontal plane H is defined as being perpendicular to this vertical axis A.
- These two faces are parallel and extend parallel to a plane P.
- These two faces are separated by a distance which is the thickness of the filter 42.
- Each of the two faces has a width and a length (or dimensions) in the plane P which are greater (or even much greater, that is to say at least five times greater) than the thickness.
- the filter 42 extends mainly along the plane P.
- the air passes through the filter 42 from its lower face 426 to its upper face 427, so that the particles accumulate on the lower face 426.
- the particles are able to fall by gravity into the storage container 50, which is fixed to the box 41 on the side of the lower face 426.
- the storage container 50 is thus facing the lower face 426.
- the filter 42 is positioned in the housing 41 (or more generally on the support 41) such that the plane P in which the filter 42 extends is horizontal.
- the storage container 50 is always located below the filter 42.
- the particles are detached regularly from the lower face 426 of the filter 42 and fall into the container 50.
- the action of gravity is assisted by vehicle or machine vibrations. The unclogging of the filter 42 thus takes place naturally in operation.
- the capture system 1 also contains a device 60 for unclogging the filter 42 which is capable of causing the particles to fall from the filter 42 into the storage container 50.
- This unclogging device 60 (shown schematically in FIG. 1 ) is connected to the support 41 (or directly to the filter 42) and its action thus complements the action of gravity.
- this unclogging device 60 comprises an air flow generator.
- This generator is for example a fan which blows air in the direction of the lower face 426 in order to detach the particles therefrom.
- the unclogging device 60 comprises a duct and at the end of this duct a nozzle (not shown), this nozzle making it possible to direct the flow of air from the generator towards the filter 42.
- This generator is for example a vacuum cleaner which generates a flow of air moving away from the lower face 426 in order to suck the particles out of this face lower 426.
- the generator is a fan which blows air towards the upper face 427 (against the flow) in order to detach the particles therefrom.
- the generator is for example the vacuum source 20, which is then connected to the filter 42 by a conduit, which avoids using a separate air source.
- An example of this embodiment is shown in Figure 5.
- the generator is associated with a solenoid valve 65 which is mounted on the conduit 30 which already connects the filtration system 40 (upstream) and the vacuum source 20 (Downstream), and which is also mounted on the conduit 30 downstream of the vacuum source 20.
- the solenoid valve 65 also makes it possible to modulate the power of the air flow.
- the air circulates in the circuit 30 of the filtration system 40 towards the source of depression 20 then exits outside (the direction of circulation of the air is indicated by the arrows on solenoid valve 65).
- the air circulates through the solenoid valve 65 in the opposite direction (the direction of the arrows on the solenoid valve 65 would then be reversed with respect to figure 5).
- the vacuum source 20 draws in air from outside to direct it towards the filter 42 in order to detach the particles.
- the unclogging device 60 is a vibrator which is able to vibrate the filter 42 so as to detach the particles.
- FIG. 4 shows another embodiment of the invention.
- the filter 42 extends mainly along a plane P which presents with the horizontal plane H a non-zero angle [3 which is less than or equal to, or strictly less than, 90°.
- the filter 42 is therefore inclined with respect to the horizontal.
- the filter 42 is advantageously oriented such that the pleats 428 of the filter 42 extend in vertical planes in order to facilitate the fall of the particles into the storage container 50.
- the filter 42 is in a horizontal position. This corresponds to the case where the angle [3 is zero (ie equal to 0°).
- the housing 41 (or more generally the support 41) is provided with a closing mechanism which seals the housing 41 to avoid any contact of the particles with the operator.
- the various openings on the outside of the box 41 are able to be closed in a sealed manner.
- the inlet orifice 411 and the outlet orifice 412 are capable of being closed by plugs, and the opening of the box 41 towards the storage container 50 is suitable for being closed by a closure (for example a cover provided with a gasket on its periphery.
- the storage container 50 is also advantageous for the storage container 50 to be provided with a closing mechanism which makes this storage container 50 sealed to avoid any contact of the particles with the operator.
- the drain orifice 55 is capable of being closed off by a plug.
- the face of the storage container which is open to the outside (for example the upper face) when the storage container 50 is separated from the box 41 is capable of being closed by a cover 57.
- this cover 57 is articulated with a side wall of the storage container 50 and comprises a single leaf which covers the entire upper face of the container 50, as illustrated in FIG. 3 (lid in the closed position).
- the lid 57 comprises two flaps which fold down on the upper face of the container 50 to close it.
- the closure of the storage container 50 by a closure mechanism can be carried out in addition to, or in replacement of, a closure of the box 41 by another closure mechanism.
- the storage container 50 In operation, or during a maintenance operation, the storage container 50 is disassembled, emptied and assembled to the support 41 several times during the life of the filter 42. In some cases, the storage container 50 can be dimensioned from such that it does not need to be emptied throughout the life of the filter 42. In this case, the storage container 50 is changed, and the filter 42 is emptied or changed, simultaneously. It is then advantageous for the storage container 50 to be fixed and irremovable to the support 41 and for this support to be a box 41. Thus, the manufacture of the capture system 1 is simplified.
