AI Technical Summary
Conventional railway braking systems face challenges in secure attachment and assembly due to limited access and space constraints, particularly when the space between the braking unit and the support is small, making it difficult to maneuver tools and secure the mounting block in the allocated assembly direction.
The railway braking system incorporates a mounting block with a distinct securing mechanism that allows mechanical attachment in a direction perpendicular to the assembly direction, utilizing a mounting block with support faces and fastening members that extend through orifices, enabling secure fixation outside the typical assembly space, and a suspension mechanism for additional stability.
This design facilitates easier assembly and disassembly by allowing secure attachment of the braking system in directions other than the assembly direction, particularly useful in confined spaces, enhancing the system's convenience, simplicity, and economic feasibility.

Description
[0001]TITLE: Railway braking system for a railway vehicle and railway vehicle provided with such a system Technical field of the invention The invention relates to the field of braking of railway vehicles. It relates more particularly to a braking system for a railway vehicle with brakes having at least one lining, configured to act on a braking member of said railway vehicle via said at least one lining. It also relates to railway vehicles comprising such systems. State of the art Railway vehicles known as having brakes having at least one lining are generally equipped with braking systems with service and / or parking brake cylinders, comprising for example a piston movable under the effect of a pressurized fluid,the movement of this piston actuating a braking linkage and causing a braking action such as the clamping of a brake disc by the lining of this linkage. The cylinder and the linkage form what can be called a braking unit. Such a braking system is mounted on the railway vehicle, to be in contact with the brake discs or with the wheels. This braking system can be mechanically secured to a support formed directly or indirectly by a bogie, or by an axle fixed to the bogie, or by another device such as a drive motor or gearbox also mounted on the bogie. The braking action generates forces which can be transmitted, via levers and the connection device, to the support to which the braking system is secured. In particular, when the braking system is provided with force transmission rods which are mechanically secured on the one hand,on lining carriers and on the other hand, to the support to which the braking system is secured, a major part of the forces can be transmitted to the support via the force transmission rods. In particular, the braking system may comprise a fixing interface secured to the braking unit and to which the force transmission rods are secured. This fixing interface may have fixing holes for its securing to the vehicle support. Generally, the fixing interface is mounted on the unit, with the force transmission rods which are secured to the lining carriers, before mounting on the support. Then, the system formed by the unit and the fixing interface is assembled to the support, with the lining carriers arranged on either side of the disc or the wheel of the vehicle, the unit which extends longitudinally along a radius of the disc or the wheel,and the fixing interface which is opposite the support, in a direction for example orthogonal to that of extension of the unit. To secure the fixing interface with the support, mounting screws are introduced, for example vertically, from the side of the support which is opposite the unit, through the support to the fixing holes. It is therefore necessary to have both access to the side of the support which is opposite the unit and space to pass a tool there and maneuver it. Statement of the invention The invention relates to a railway braking system of the type described above, having improved performance, while being simple, convenient and economical. The invention thus has as its subject, in a first aspect, a railway braking system for a railway vehicle with brakes with at least one lining,configured to act on at least one rotating braking member of the railway vehicle via the at least one lining and comprising a braking unit provided with a braking linkage having the at least one lining and a brake cylinder configured to actuate the braking linkage, the braking unit extending in a general longitudinal direction and generally orthogonal to an axis of rotation of the at least one rotating braking member, and a fixing interface secured to the braking unit and configured to be fixed on a support of the railway vehicle in an assembly direction generally perpendicular to the general longitudinal direction and to the axis of rotation,characterized in that the fixing interface is provided with a mounting block configured to be fitted by interlocking with the vehicle support in the assembly direction and having at least one bearing face and fixing members of the first bearing face which extend in a direction distinct from the assembly direction. The system according to the invention uses, for its fixing to the vehicle support, cooperation by the bearing face of the mounting block which may preferably be planar. The assembly, in particular the interlocking of the mounting block, is carried out in the general assembly direction which is generally perpendicular to the general longitudinal direction of the braking unit and to the axis of rotation of the rotating braking member. However, depending on the general arrangement of the railway braking system in relation to the vehicle support and in relation to the rotating braking member of the vehicle,access can be reduced in the general assembly direction. Thanks to the system according to the invention, the mechanical securing of the mounting block is done in a direction distinct from the assembly direction. For example, the general longitudinal direction of the braking unit is substantially horizontal while the general assembly direction is substantially vertical. In other words, the securing of the mounting block is possible outside the space allocated in the general assembly direction. In particular, the securing of the mounting block can be done rather in a direction substantially parallel to the axis of rotation of the rotating braking member of the vehicle, or rather substantially parallel to the general direction of extension of the braking unit. The system according to the invention therefore facilitates the securing of the braking system with the vehicle, especially when the space is quite reduced between the braking unit and the support or,in other words, above and below the mounting block. Preferred, simple, convenient and economical features of the system according to the invention are presented below. The fixing members extend in a fixing direction substantially perpendicular to the assembly direction, pass at least partially through the mounting block and are configured to position it relative to the vehicle support and fix it thereto. The mounting block is provided with holes passing through and opening on the one hand onto a first bearing face and on the other hand onto a second bearing face opposite the first bearing face, whereby the fixing members are introduced from one or other of the first and second bearing faces for the assembly of the mounting block with the vehicle support. The system comprises a suspension mechanism interposed between the braking unit and the mounting block,which has a mounting face distinct from the at least one bearing face and configured for mechanically securing the suspension mechanism in the assembly direction. The braking unit comprises a connection device mechanically secured on the one hand to the suspension mechanism and on the other hand to the braking linkage, which comprises levers mounted to rotate about the connection device,and a service and / or parking brake housed at least partially in the cylinder and configured to act on the braking member by actuating the levers of the braking linkage. The mounting block is provided with at least one guide and / or coding member. The at least one guide and / or coding member is formed by a notch or a projection provided in the at least one bearing face and configured to cooperate with respectively a complementary projection or a complementary notch. The fixing interface is provided with an intermediate part configured to be mechanically secured on the one hand, with the support of the vehicle in the assembly direction and on the other hand,with the mounting block by the at least one bearing face in the direction distinct from the assembly direction. The system comprises at least one lining holder on which is mounted at least one said lining and at least one force transmission rod mechanically secured on the one hand, to the intermediate part of the fixing interface and on the other hand, to the lining holder. The intermediate part is provided with a body having a central recess in which the mounting block is fitted and at least one complementary bearing face, for example projecting into the central recess, provided to come opposite the at least one bearing face of the mounting block. The invention also relates, according to a second aspect, to a method of assembling and / or disassembling a railway braking system as described above on a railway vehicle,comprising a step of fitting and / or unfitting the mounting block of the fixing interface with the vehicle support in the assembly direction, and of mechanically securing the mounting block in a direction distinct from the assembly direction by the at least one bearing face and by the fixing members of the first bearing face. When the fixing interface of the railway braking system is provided with an intermediate part configured to be mechanically secured on the one hand, with the vehicle support in the assembly direction and on the other hand, with the mounting block by the at least one bearing face in the direction distinct from the assembly direction, the method comprises a step of mounting the intermediate part with the vehicle support in the assembly direction,then to fit the mounting block with the intermediate part in the assembly direction and then to mechanically secure the mounting block in the direction distinct from the assembly direction. The method further comprises a step of unfastening the mounting block from the intermediate part in the direction distinct from the assembly direction, then to unfit the mounting block from the intermediate part in the assembly direction, then to dismantle the intermediate part from the vehicle support. The invention also relates, according to a third aspect, to a railway vehicle with brakes having at least one lining, comprising at least one railway braking system as described above,configured to act on at least one rotating braking member of said railway vehicle via said at least one lining. The at least one rotating braking member is formed by a disc or by a wheel. Brief description of the figures The disclosure of the invention will now continue with the description of exemplary embodiments, given below for illustrative and non-limiting purposes, with reference to the appended drawings. Figure 1 partially illustrates, in side view and in partial section, a railway vehicle provided with a railway braking system secured to a support of the vehicle and acting on a brake disc of the railway vehicle via linings. Figure 2 only partially and in isolation represents the railway braking system,which is also partially disassembled. Figure 3 represents a first operation of mounting the railway braking system on the vehicle support. Figure 4 represents a second operation of mounting the railway braking system on the vehicle support. Figure 5 is a detailed view of the railway braking system. Figure 6 is a sectional view marked AA in Figure 5. Figure 7 is a sectional view marked BB in Figure 6. Figure 8 is a view similar to that of Figure 7, taken along an offset sectional plane and showing an alternative embodiment of the railway braking system. Figure 9 is a view similar to that of Figure 7, showing another alternative embodiment of the railway braking system. Detailed description Figures 1 to 4 partially illustrate a railway vehicle 1 provided with a railway braking system 2 configured to act on a rotating braking member,formed here by a brake disc 3, of the railway vehicle 1 by means of linings 4. The railway braking system 2 is mechanically secured to a support 5, which can be formed directly or indirectly by a bogie, or by an axle support fixed to the bogie, or by another device of the drive motor or gearbox type also mounted on the bogie. Due to the movements inherent in the railway vehicle 1 both in the rolling phase and in the braking or debraking phase, the railway braking system 2 is here mounted "suspended" relative to the support 5. The railway braking system 2 is here mechanically secured to the railway vehicle 1 only by means of the support 5, through a fixing interface 6 itself mechanically secured on the one hand,to a connection device 7 and to force transmission rods 8 of the railway braking system 2. The braking action generates braking forces which are therefore transmitted to the railway vehicle 1 via the support 5 and by means of the fixing interface 6, the connection device 7 and the force transmission rods 8. With reference to figures 1 to 4 which show the railway braking system 2 with or without the support 5 and the brake disc 3 of the vehicle 1, the railway braking system 2 comprises a braking unit which is provided with a braking linkage 10 and a service and / or parking brake 11 configured to act on the brake disc 3 via the braking linkage 10. The service and / or parking brake 11 conventionally comprises a cylinder 9,here of the pneumatic type. The braking linkage 10 is provided with movable levers 12 mechanically secured at one end to the cylinder 9 of the service and / or parking brake 11, and lining carriers 13 which are mechanically secured to a respective opposite end of the levers 12 and which carry the linings 4. The force transmission rods 8 are mechanically secured to the lining carriers 13. The movable levers 12 are configured to be actuated by the service and / or parking brake 11. The connection device 7, which is part of the braking unit, here comprises a lower part 14, an upper part 15 connected to the upper part by an intermediate part (not shown), and pivot axes 16 around which the levers 12 are movably mounted. In the example illustrated, the lower part 14,the upper part 15 the intermediate part are formed in a single piece. The cylinder 9 of the service and / or parking brake 11 is therefore here subject to the connection device 7 by means of the levers 12 which it carries in a pivoting manner. The connection device 7 further comprises an attachment portion 17 by which it is fixed to the fixing interface 6, together with the cylinder 9 and the levers 12. The railway braking system 2 further comprises a suspension mechanism 18 interposed between the fixing interface 6 and the connection device 7 to which the brake cylinder 9 is connected via the levers 12. In the example illustrated, the braking unit extends in a general longitudinal direction L and generally orthogonal to an axis of rotation R of the brake disc 3. In addition, the braking system 2 is here assembled, via the fixing interface 6,to the support 5 of the vehicle 1 in an assembly direction A generally perpendicular to the general longitudinal direction L and to the axis of rotation R. For example, the general longitudinal direction L is substantially horizontal while the assembly direction A is substantially vertical. The fixing interface 6 is here provided with a mounting block 20 and an intermediate part 21, also called an anchoring part. In the example illustrated, the fixing interface 6 is configured so that the mounting block 20 is directly mechanically secured on the one hand, to the suspension mechanism 18 and on the other hand, to the intermediate part 21 which is in turn configured to also be directly mechanically secured to the support 5 of the vehicle 1. In particular,the mounting block 20 and the intermediate part 21 are configured to be assembled by fitting together in the assembly direction A and mechanically secured to each other in a direction distinct from the assembly direction A. The intermediate part 21 is provided with a first body 22 from which extensions 23 project to which the force transmission rods 8 are assembled. The first body 22 has a central recess 24 in which the mounting block 20 is fitted and two walls forming so-called complementary bearing faces 25 each provided projecting into the central recess 24 and facing one another. The first body 22 further has a plurality of first fixing orifices opening into the central recess 24, including first positioning and fixing orifices 27 and first fixing orifices 26 provided here through the complementary bearing faces 25 only. The first fixing orifices 26,27 are here all oriented in the direction distinct from the assembly direction A. The first body 22 also has other fixing orifices 29 arranged through the first body 22, oriented in the assembly direction A, and provided to receive fixing screws 28 for the mechanical securing of the intermediate part 21 with the support 5 of the vehicle 1. The mounting block 20 is provided with a second body 30 defining here two bearing faces 31, also called first bearing face and second bearing face, where a plurality of second fixing orifices open, including a second positioning and fixing orifice 33 and second fixing orifices 31. The second body 30 of the mounting block 20 is fitted into the central recess 24 of the first body 22 of the intermediate part 21 so that the complementary bearing faces 25 are each located in opposite and in the immediate vicinity of the support faces 31,and the railway braking system 2 comprises members for fixing the bearing faces 31 with the complementary bearing faces 25 including, in the illustrated example, a positioning and fixing member 35 passing through at least one of the first positioning and fixing orifices 27 and the second centering and fixing orifice 33, and fixing members 34 passing through at least some of the first fixing orifices 26 and the second fixing orifices 32. The fixing members thus extend in the direction distinct from the assembly direction A. In addition, the bearing faces 31 and complementary bearing faces 25 are here generally planar and arranged so as to form a planar support between the mounting block 20 and the intermediate part 21. Figures 3 and 4 show the method of assembling the railway braking system 2 on the support 5 of the vehicle 1 via the fixing interface 6. In Figure 3,the intermediate part 21 together with the force transmission rods 8 are mechanically secured to the support 5 via the fixing screws 28 introduced in the assembly direction. Access is particularly easy here without the presence of the rest of the railway braking system 2. In other words, the intermediate part 21 is mounted separately on the support 5. The rest of the railway braking system 2, including in particular the cylinder 9, the levers 12, the connection device 7, the suspension mechanism 18 and the mounting block 20 already assembled, can then be approached to the intermediate part 21 in the assembly direction. In Figure 4, the mounting block 20 is fitted into the intermediate part 21, with the bearing faces and complementary bearing faces facing each other and in close proximity,then the positioning and fixing member 35 is introduced through one of the first positioning and fixing orifices 27 and the second positioning and fixing orifice 33, then the fixing members 34 are introduced through first fixing orifices 26 and second fixing orifices 32. As the fixing members extend in the direction distinct from the assembly direction, they can be maneuvered with a tool 40, for example of the socket wrench type or the like, having a handle which runs along the assembly direction, in a particularly reduced space requirement. More generally, the method of assembling and / or disassembling the railway braking system 2 comprises a step of fitting and / or disengaging the mounting block 20 of the fixing interface 6 with the support 5 according to the assembly direction,and mechanically securing the mounting block 20 in a direction distinct from the assembly direction. When the fixing interface 6 is provided with an intermediate part 21 like that described above, the method first comprises a step of mounting the intermediate part 21 with the support 5 in the assembly direction, then fitting the mounting block 20 with the intermediate part 21 in the assembly direction and then mechanically securing the mounting block 20 in the direction distinct from the assembly direction. For disassembly, the method further comprises a step of unfitting the mounting block 20 from the intermediate part 21 in the direction distinct from the assembly direction, then unfitting the mounting block 20 from the intermediate part 21 in the assembly direction, and then dismounting the intermediate part 21 from the support 5. Figure 5 is a detail of Figure 4,showing the assembly of the suspension mechanism 18 with the attachment portion 17 of the upper part 14 of the connection device 7, the mounting block 20 and the intermediate part 21. Figures 6 and 7 are sections marked AA and BB respectively in Figures 5 and 6. In Figure 6, the second body 30 of the mounting block is fitted into the central recess 24 of the first body 22 of the intermediate part so that the complementary bearing faces 25 are each located opposite and in the immediate vicinity of the bearing faces 31. The fixing members 35, 34 of the bearing faces 31 with the complementary bearing faces 25 pass through one of the first positioning and fixing orifices 27 and the second positioning and fixing orifice 33, and also at least some of the first fixing orifices 26 and the second fixing orifices 32. The fixing members thus extend in the direction distinct from the assembly direction. In addition,the bearing faces 31 and complementary bearing faces 25 form a flat support between the mounting block and the intermediate part. In other words, the fixing members 34, 35 extend in the fixing direction substantially perpendicular to the assembly direction, pass at least partially through the mounting block and are configured to position it relative to the support 5 of the vehicle 1 and fix it to the latter via the intermediate part. In particular,the securing of the mounting block 20 can be done in a direction substantially parallel to the axis of rotation of the disc. The fixing members can be introduced from one or other of the bearing faces 31 for the assembly of the mounting block. Figure 7 shows in more detail the securing of the suspension mechanism 18 with the mounting block 20 and the attachment portion 17 of the upper part 14 of the connection device 7. The railway braking system 2 comprises complementary fixing screws 45 inserted into holes 48 formed in a mounting face 47 of the mounting block 20, distinct from the bearing faces 31. In the example illustrated, the suspension mechanism 18 is provided with a first and a second damping buffer 49, 50 mounted on either side of the attachment portion 17. Complementary holes are formed so that the complementary fixing screws 45 pass through the damping buffer 50,the attachment portion 17 and the damping pad 49 before being introduced into the holes 48 which are tapped. Spacer rings can be housed in the complementary holes to limit the tightening of the complementary fixing screws 45 and the deformation of the damping pad(s) 49, 50. Figure 8 shows an alternative embodiment of the system, in which the same references as above are used for similar elements, but added with the number 100. The mounting block 120 is provided with at least one guide and / or keying member formed here by a notch 150 formed in the second body 130 and in particular in the bearing face, while a complementary projection 155 is formed on the complementary bearing face 125 of the intermediate part 121. More generally,the at least one guide and / or keying member is formed by a notch or a projection provided in the at least one bearing face and configured to cooperate with respectively a complementary projection or a complementary notch of the complementary bearing face. Figure 9 shows an alternative embodiment of the system, in which the same references as above are used for similar elements, but added with the number 200. The suspension mechanism 218 differs from that described above in that it is provided with several cylinders 260 mounted suspended in the second body 230 of the mounting block 220, and the attachment portion 217 of the connection device 207 is directly subject to the cylinders 260 through the mounting face 247. In the railway braking system 2 described above, the assembly, in particular the fitting of the mounting block 20,is carried out in the general assembly direction which is generally perpendicular to the general longitudinal direction and to the axis of rotation of the rotating braking member. However, depending on the general arrangement of the railway braking system in relation to the vehicle support and in relation to the disc, access may be reduced in the general assembly direction. Thanks to the system according to the invention, the mechanical securing of the mounting block is carried out in a direction distinct from the assembly direction. In other words, the securing of the mounting block is possible outside the space allocated in the general assembly direction. In particular, the securing of the mounting block may instead be carried out in a direction substantially parallel to the axis of rotation of the rotating braking member of the vehicle,or rather substantially parallel to the general direction of extension of the braking unit. The system according to the invention therefore facilitates securing the braking system with the vehicle, especially when the space is quite small between the braking unit and the support or, in other words, above and below the mounting block. Variants not illustrated are presented below. The intermediate piece may be formed in one piece with the support. There may be more or fewer members for fastening the mounting block with the intermediate piece and / or the support. The fastening members extend in a fastening direction substantially perpendicular to the assembly direction, and in particular substantially parallel to the general direction of extension of the brake braking unit rather than substantially parallel to the axis of rotation of the disc. The suspension mechanism comprises only one suspended cylinder,with or without a suspension rod. The railway braking system has no suspension mechanism. The service and / or parking brake may be electromechanical, or hydraulic, or electric, or even manual rather than pneumatic. More generally, the invention is not limited to the examples described and shown.,
