    Field of the invention
    The present invention relates to vehicles, especially motor vehicles and also railway rolling stock. More specifically, the invention relates to the braking of rail vehicles and rolling stock. The invention further relates to brake pads for disc brake assemblies for these vehicles and railway rolling stock.
    It should be noted that according to the invention, the vehicle can be of any type and can in particular be a car, a truck or a bus. Similarly, railway rolling stock can be a train, a tram or even a metropolitan.
    Technological background of the invention
    A railway vehicle or rolling stock generally includes a braking system. The braking system can in particular be a disc brake system. The braking system then comprises a disc integral with a wheel or an axle of the vehicle or the railway rolling stock. So when the wheel, or the axle, rotates to allow the rail vehicle or rolling stock to move, the disc also rotates.
    Thus, to brake the rail vehicle or rolling stock, the disc brake system includes disc friction means. The friction means notably comprise two soles which each carry a lining which comprises a friction material. The friction material is configured to come into contact with the disc. The two soles carrying the friction linings are arranged on either side of the disc so as to take it in pincers when the brake system is applied.
    However, when the friction material comes into contact with the disc while the disc is rotating, the friction material emits particles harmful to the environment. The braking systems are therefore polluting.
    This is why it is known to arrange a device for removing particles from braking in the braking system. The suction device is intended to suck up the particles from the brake shortly after they have been emitted.
    However, the suction device is mainly configured to operate when the brake pad is in a "factory outlet" configuration. Thus, during use, the suction of the braking particles may prove to be less effective.
    Object of the invention
    An object of the invention is to provide a brake pad for a disc brake assembly whose performance remains constant, even improves or at least is little deteriorated over time.
    Brief summary of the invention
    To do this, a brake pad is provided according to the invention for a disc brake assembly, comprising a lining made of friction material and a sole supporting the lining, in which:
    - the filling includes:
    o a friction face and a fixing face, o a rear edge, located on the side where the disc is able to leave an interface with the pad when the disc rotates in a direction of advance of the vehicle, and a front edge , an inner edge and an outer edge, and a collection groove open on the friction face and arranged near the rear edge, the collection groove opening onto one of the interior and exterior edges,
    - The sole has a hole in fluid communication with the collecting groove, the hole being connected to a source of vacuum via communication means, characterized in that the lining comprises a rear zone comprising the rear edge and the collecting groove , the rear zone comprising a chamfered portion so that an area of a friction surface of the rear zone increases when a thickness of the rear zone decreases, the collecting groove being arranged at a distance from a free surface of the chamfered portion and comprising a cross section extending obliquely towards the free surface of the chamfered portion.
    Thus, as the brake pad becomes worn during use, the area of the friction surface of the rear area which is arranged between the collecting groove and the rear edge of the lining increases. As a result, braking particles will be emitted towards the rear of the vehicle, downstream of the collection groove. However, since the cross section of the collection groove extends at an angle towards the free surface of the chamfered portion, a distance between this free surface and the collection groove increases less, or even remains the same, than if the cross section of the collecting groove extended perpendicularly to a plane comprising the face for fixing the lining. The efficiency of the collection of braking particles is therefore preserved or slightly altered, or even improved during the use of the brake pad.
    In addition, the chamfered portion arranged in the rear zone ensures less abrupt contact between the lining and the disc. The brake pad thus has better acoustic performance, the noise during braking being reduced.
    In addition, the chamfered portion forms a ramp for the evacuation of water, for example due to precipitation or from molten frost.
    Note also that "friction surface" means the portion of the friction surface of the lining which is able to actually come into direct contact with the disc during braking.
    In addition, in various embodiments of the invention, recourse may also be had to one and / or the other of the following arrangements:
    - The cross section of the groove forms an angle with a straight line normal to the fixing face between 20 ° and 80 ° or between 30 ° and 60 ° or preferably between 40 ° and 50 °;
    - The cross section of the groove extends substantially parallel to a section of the free surface of the chamfered portion;
    a distance between the collection groove and the free surface of the chamfered portion is constant along the collection groove;
    - The lining comprises a rear zone comprising the rear edge, the rear zone further comprising a chamfered portion so that an area of a friction surface of the rear zone increases when a thickness of the rear zone decreases;
    - an area of the chamfered portion of the front area and an area of the chamfered portion of the rear area are substantially equal;
    the chamfered portions of the rear and rear zones are flat, an angle formed between the chamfered portion of the rear zone and a plane comprising the fixing face is substantially equal to an angle formed between the chamfered portion of the rear zone and the plane comprising the fixing face;
    - the collecting groove is dug directly in the friction material, up to the surface of the sole;
    - the collection groove extends between a through end and a blind end, the hole in the sole opening in the groove near the blind end.
    In addition, there is also provided according to the invention a disc brake assembly comprising a disc and two brake pads as described above and arranged on either side of the disc.
    Finally, according to the invention, a disc brake system is provided which comprises a disc brake assembly as described above and in which the disc is integral with an axle or a wheel.

    Detailed description of an embodiment of the invention
    Note that for the sake of clarity, only the elements useful for understanding the embodiments described have been shown and will be detailed.
    In addition, unless otherwise specified, the expressions substantially, approximately etc. mean that a slight variation from the nominal value considered is possible, in particular by a small percentage, in particular to within 10%.
    FIGS. 1 and 2 show a disc brake system 19 according to the invention for a vehicle. In this embodiment, the vehicle is a motor vehicle, in this case a light car. It should be noted, however, that the invention can be implemented for any type of vehicle, such as a tractor-trailer, a bus or an agricultural tractor, or for any type of railway rolling stock, such as a locomotive or a wagon. .
    The disc brake system 19 according to the invention comprises a disc 9, of axis A secured to a wheel of the vehicle. The disc 9 has a side face 9A and an opposite side face 9B. The side faces 9A, 9B are perpendicular to the axis A. The disc 9 is also connected to a transmission mechanism, in particular by means of a hub, itself connected to an engine of the vehicle. Thus, the transmission mechanism makes it possible to transmit to the vehicle wheel, via the disc 9, a rotational movement around the axis A, in order to move the vehicle.
    In addition, the disc brake system 19 comprises a caliper 5 which encloses, so as to sandwich, a portion of the disc 9. As illustrated in particular in FIG. 2, the caliper 5 is in the form of a main body 50 which has a general U shape so as to enclose the disc 9. In addition, the main body 50 comprises a cavity making it possible to house a piston 55. The caliper 5 also includes two fingers 51, 52. The piston 55 is able to exert a force PF in a direction A2 identified in Figure 1 and which is parallel to the axis A of the disc.
    In Figure 1, there is shown a direction of rotation FW of the disc 9 which corresponds to a forward movement of the vehicle. A tangential direction T has also been shown on a circumference of the disc 9.
    We also define a rear side and an opposite front side. The rear side corresponds to the side where the disc 9 leaves the interface with the caliper 5 when the disc 9 rotates in the direction of advance of the vehicle. The front side is the opposite side and corresponds to the side where the disc 9 enters the interface with the caliper 5 when the disc 9 rotates in the direction of advance of the vehicle. In addition, a direction which goes from the inside to the outside is defined for a radial direction going from the axis A towards the circumference of the disc 9.
    The disc brake system 19 includes a caliper support 6 which is attached to a member of the vehicle. This member can in particular be a vehicle suspension arm. In addition, the stirrup support 6 comprises two bridges 61, 62 arranged at two rear and front longitudinal ends of the stirrup 5 and a connecting arc 63 which connects the two bridges 61, 62. The trigger guard 61 is a rear trigger guard and the trigger guard 62 is a trigger guard.
    The disc brake system 19 also comprises two brake pads 10A, 10B housed in the caliper 5. The two brake pads 10A, 10B are arranged on either side of the disc 9. The brake pad 10A is arranged facing the side face 9A of the disc 9. The brake pad 10B is arranged facing the side face 9B of the disc 9. Thus, the two brake pads 10A, 10B are arranged symmetrically with respect to a plane comprising the disc 9 and perpendicular to the axis A of the disc 9.
    The piston 55 of the caliper 5 is arranged to exert the force PF on the brake pad 10A so that the two pads 10A, 10B come into contact with the disc 9 so as to brake the vehicle when the disc brake system 19 is actuated by a driver of the vehicle. Note that in the example illustrated, the stirrup 5 is mounted "floating" in the stirrup support 6, along the axis A. Thus, the stirrup 5 can move parallel to the axis A in particular to compensate for the progressive wear of the pads 10A, 10B. On the other hand the stirrup 5 is held integral with the stirrup support 6 according to the other translations and potential rotations. Floating mounting is usually carried out using sliding columns along the A axis.
    We will now describe in more detail, the brake pad 10A. Taking into account the effects of symmetry, the following description also applies to the 10B brake pad.
    The pad 10A is illustrated in particular in FIGS. 3 and 4. Thus, the brake pad 10A comprises a sole 20 which supports a friction lining 22. The sole 20 is in the form of a solid metal plate and of substantially thickness constant. The sole 20 has a rear arm 24 and a front arm 26 which make it possible to fix the sole 20 to the main body 55 of the stirrup 5 by means of hooks 28. The sole 20 has a fixing face to which the lining of the friction 22. The face opposite to the fixing face is fixed to the piston 55 as illustrated in FIG. 2.
    The friction lining 22 is in the form of a body of friction material capable of coming into contact with the lateral face 9A of the disc 9 in order to brake the vehicle. The friction material is sometimes called "ferodo". The friction lining 22 therefore comprises a friction face 30 intended to come into direct contact with the lateral face 9 of the disc 9. The friction lining 22 also includes a fixing face 32, opposite to the friction face 30, and fixed directly to the fixing face of the sole 20. In addition, with reference to the previously defined sides, the friction lining 22 has a rear edge 34 and an opposite front edge 36. The friction lining 22 also has an inner edge 38 and an outer edge 39.
    When the disc brake system 19 is actuated, the contact between the friction face 30 of the friction lining 22 of the brake pad 10A and the side face
    9A of disc 9 generates the emission of polluting brake particles. These braking particles correspond to particles of the friction material which detach from the friction lining 22 by abrasion with the lateral face 9A of the disc 9 as well as to particles which detach from the disc 9. This is why the disc brake system 19 comprises means for sucking up the braking particles described below.
    The friction lining 22 has a collecting groove 3. The collecting groove 3 is open on the friction face 30 and is arranged near the rear edge 34 of the friction lining 22. Thus, in forward movement of the vehicle, the braking particles are entrained towards the collection groove 3, which improves the collection efficiency. When the vehicle is braked while it is moving forward, the brake particles are emitted towards the front FW, with reference to the vehicle's forward direction. Thus, the capture of the braking particles is all the more effective as the collecting groove 3 is disposed near a rear edge of a portion of the friction face 30 which is directly in contact with the lateral face 9A of the disc. 9.
    As shown in Figure 2, the collection groove 3 is single, straight and continuous. It is of constant width. In addition, the collecting groove 3 is directly hollowed out in the friction material, up to the sole 20.
    The collecting groove 3 further extends between a through end 31 and a blind end 33. The open end 31 is disposed on the inner edge 38 of the friction lining 22. The blind end 33 is arranged near the outer edge 39. Of course, the through end 31 can also be arranged on the outer edge 39 of the friction lining 22. The blind end 33 can also be disposed near the inner edge 38 of the friction lining 22.
    The sole 20 has a hole 17 which opens into the collecting groove 3. The hole 17 is substantially opposite the blind end 33. The hole 17 can more generally be placed near the blind end 33. The hole 17 is also in pneumatic communication with the collecting groove 3.
    In addition, as illustrated in FIG. 2, the disc brake system 19 comprises a suction device 8 in pneumatic communication with the hole 17 by means of a flexible pipe 40 which passes through the main body 50 of the caliper 5 The suction device 8 comprises a vacuum source, for example a turbine, and a filter making it possible to filter the air sucked in and loaded with braking particles. The vacuum source is configured to vacuum from the collecting groove 3.
    Thus, the hole 17 is connected to a source of vacuum via communication means which here comprise the flexible pipe 40.
    In addition, the friction lining 22 comprises a rear zone 60 and a front zone 62. The rear zone 60 comprises the rear edge 34 of the friction lining 22 and the collection groove 3. The front zone 62 comprises the front edge 36 The rear zone 60 and the front zone 62 are arranged one after the other and are in contact. They each occupy substantially one half of the friction lining 22. FIG. 4 shows an axis M which delimits the border between the rear zone 60 and the front zone 62.
    The rear zone 60 has a friction surface 60A which is a surface capable of coming into direct contact with the lateral face 9A of the disc 9 when the brake system 19 is actuated. Likewise, the front zone 62 includes a friction surface 62A which is a surface capable of coming into direct contact with the lateral face 9A of the disc 9 when the brake system 19 is actuated.
    The rear zone 60 comprises a chamfered portion 64 which connects the friction surface 60A of the rear zone 60 and the rear edge 34 of the friction lining 22 so that a thickness of friction lining 22 is greater at the level of a portion which comprises the friction surface 60A only at the level of a portion which comprises the rear edge 34. Thus, when the thickness of the rear zone 60 decreases, in particular due to the wear due to the use of the pad brake 10A, an area of the friction surface 60A of the rear zone 60 increases.
    Likewise, the front zone 62 comprises a chamfered portion 66 which connects the friction surface 62A of the front zone 62 and the front edge 36 of the friction lining 22 so that a thickness of friction lining 22 is greater at the level of a portion which comprises the friction surface 62A only at the level of a portion which comprises the front edge 36. Thus, when the thickness of the front zone 62 decreases, in particular due to wear due to the With the use of the brake pad 10A, an area of the friction surface 62A of the front zone 62 increases.
    It is therefore understood, in particular with the aid of FIG. 3, that the chamfered portions 64, 66 respectively of the rear zone 60 and of the front zone 62 do not respectively form part of the friction surfaces 60A, 62A of the rear zones 60 and before 62.
    Note that in the present embodiment, an area of a free surface of the chamfered portion 64 of the rear region 60 and an area of a free surface of the chamfered portion 66 of the front region 62 are substantially equal. Thus, in the "factory outlet" configuration, the area of the friction surface 60A of the rear region 60 is substantially equal to the area of the friction surface 62A of the front region 62.
    According to variants, these two areas may differ. In particular, the air of the free surface of the chamfered portion 66 of the front zone 62 may be greater than the area of the free surface of the chamfered portion 64 of the rear zone 60. Thus, during the use of the brake pad 10A, the area of the friction surface 62A of the front area 62 will tend to become larger than the area of the friction surface 60A of the rear area 60. As a result, when the brake system 19 is actuated while the vehicle is moving forward, more braking particles will be emitted upstream of the collecting groove 3 and this towards the collecting groove 3. The efficiency of the capture of the braking particles is therefore preserved at over time, the effect indicated above compensating for the effect of the wear of the braking system 19.
    In addition, as illustrated in FIG. 4 in particular, the chamfered portions 64, 66 are planar. The free surface of the chamfered portion 64 thus forms, with a plane which includes the fixing surface 32 of the friction lining 22, an angle which is substantially equal to an angle formed between the free surface of the chamfered portion 66 and the plane which has the fixing surface 32.
    In addition, the chamfered portions 64, 66 respectively of the rear 60 and front zones 62 also have the property of allowing less abrupt contact between the lateral face 9A of the disc 9 and the friction lining 22 when the braking system 19 is actuated. Thus, the noise and vibrations generated during braking are reduced. In addition, the chamfered portions 64, 66 form ramps for discharging water, for example from precipitation.
    In addition, as can be seen in FIG. 3, the chamfered portion 64 of the rear zone 60 has an internal border 64A and an external border 64B which are respectively partially coincident with the lower 38 and external 39 edges of the friction lining 22 The inner edge 64A has a relatively shorter length than the outer edge 64B.
    Likewise, the chamfered portion 66 of the rear zone 62 has an inner edge 66A and an outer edge 66B which are respectively partially coincident with the lower 38 and outer 39 edges of the friction lining 22. The inner edge 66A has a relatively long less important than the outer border 66B.
    In addition, as can be seen in FIGS. 3 and 4, the collection groove 3 is arranged at a distance from the free surface of the chamfered portion 64 of the rear zone 60. The collection groove 3 is arranged at a distance from the free surface of the chamfered portion 64 which is substantially constant along the collection groove 3.
    In addition, as illustrated in FIG. 4, in a cross section, the collecting groove 3 extends, from the friction face 30 to the fixing face of the sole 20, at an angle towards the free surface of the chamfered portion 64.
    According to the present embodiment, the cross section of the collecting groove 3 extends substantially parallel to the free surface of the chamfered portion 64. Thus, a distance between the collecting groove 3 and the free surface of the chamfered portion is constant even when the friction lining 22 exhibits some wear as can be seen by comparing FIGS. 4 and 5. Part of the friction lining 22 has in fact been shown in dotted lines which has disappeared following the wear of the friction lining 22.
    The effectiveness of capturing the braking particles is therefore preserved despite the wear of the friction lining 22.
    In addition, FIG. 4 shows an angle DI corresponding to an angle formed between the cross section of the collecting groove 3 and a straight line L perpendicular to the fixing face 32 of the friction lining 22. Here, the DI angle is substantially equal to 45 °. The angle DI is more specifically defined between an axis W1 of the collection groove 3 and the axis L.
    According to variants, the angle DI is between 20 ° and 80 ° or between 30 ° and 60 ° or between 40 ° and 50 °.
    FIG. 4 also shows an angle D2 corresponding to an angle formed between a straight line W2 carried by the free surface of the chamfered portion 64 and the straight line L. In the embodiment illustrated in FIG. 4, DI and D2 are equal.
    However, more generally, DI is strictly greater than 0 ° and is less than or equal to D2. According to a variant, DI is strictly greater than D2.
    Similarly, an angle formed between the free surface of the chamfered portion 64 of the rear zone 60 with a plane which includes the fixing face 32 of the friction lining 22, and which is therefore normal to the line L, is substantially identical. at an angle formed between the free surface of the chamfered portion 66 of the front zone 62 and this plane comprising the fixing face 32 of the friction lining 22.
    FIG. 6 shows a variant of the embodiment described above. Only the differences will be indicated.
    According to the variant of Figure 6, the cross section of the collection groove 3 does not extend substantially parallel to the free surface of the chamfered portion.
    It will of course be possible to make numerous modifications to the invention without departing from the scope thereof.
    The angle DI may also be between 60 ° and 80 ° and in particular be substantially equal to 70.
    We can in particular use any type of vacuum source or more generally of suction means.
    It is also possible to use any type of material for the friction lining 22.
