Description

Technical Field

[0001] The present invention relates to the field of rail vehicle braking. More specifically, it relates to a braking system for a rail vehicle, which has a brake with at least one lining, and the braking system is configured to act on the braking member of the rail vehicle through the at least one lining. The present invention also relates to a rail vehicle including the system. Background Art

[0002] A rail vehicle "with a brake having at least one lining" is usually equipped with a braking system having a service brake cylinder and / or a parking brake cylinder, including, for example, a piston that can move under the action of a pressurized fluid, and the movement of the piston actuates the braking device and causes a braking action, such as the lining of the braking device clamping the brake disc. The cylinder and the device constitute a so-called braking unit.

[0003] Such a braking system is installed on a rail vehicle and contacts the brake disc or the wheel.

[0004] The braking system can be mechanically fixed to a bracket directly or indirectly formed by a bogie, an axle fixed to the bogie, or another device of the type of a drive motor or a gearbox also installed on the bogie.

[0005] The force generated by the braking action can be transmitted to the bracket fixing the braking system through a lever and a connecting device.

[0006] In particular, when the braking system is provided with a force transmission link, where the force transmission link is mechanically fixed to the lining bracket on one hand and to the bracket fixing the braking system on the other hand, most of the force can be transmitted to the bracket through the force transmission link.

[0007] In particular, the braking system can include a fixed interface fixed to the braking unit, and the force transmission link is fixed to the fixed interface. The fixed interface can have mounting holes for fixing it to the bracket of the vehicle.

[0008] Generally, before installing the fixed interface onto the bracket, the force transmission rod is first fixed to the lining bracket so as to install the fixed interface on the unit.

[0009] Then, the system formed by the unit and the fixed interface is assembled onto the bracket, where the lining bracket is arranged on both sides of the disc or the wheel of the vehicle, the unit extends longitudinally according to the radius of the disc or the wheel, and the fixed interface is located opposite to the bracket, for example, along a direction orthogonal to the extension direction of the unit.

[0010] To fix the fixed interface to the bracket, mounting screws are vertically inserted, for example, from the side of the bracket opposite to the unit, through the bracket to reach the mounting holes.

[0011] Therefore, a passage must be provided on the side of the bracket opposite to the unit, and space must be left for inserting and operating tools. Summary of the Invention

[0012] The present invention relates to a track braking system of the above type, which has improved performance while being simple, convenient and economical.

[0013] Thus, in a first aspect, an object of the present invention is to provide a track braking system for a rail vehicle, which has a brake with at least one brake lining, the braking system being configured to act on at least one rotating braking member of the rail vehicle through the at least one brake lining, and the braking system including a braking unit and a fixing interface, the braking unit being provided with a braking device having the at least one brake lining and a brake cylinder configured to actuate the braking device, the braking unit extending in a general longitudinal direction substantially orthogonal to the rotation axis of the at least one rotating braking member, and the fixing interface being fixed to the braking unit and configured to be fixed to a bracket of the rail vehicle in an assembly direction substantially perpendicular to the general longitudinal direction and the rotation axis, characterized in that the fixing interface is provided with a mounting block, the mounting block being configured to be nested and mounted with the bracket of the vehicle along the assembly direction, and having at least one support surface and a member for fixing the first support surface, the member extending in a direction different from the assembly direction.

[0014] The system according to the present invention utilizes the cooperation of the support surface of the mounting block to attach it to the bracket of the vehicle, and the support surface is preferably flat.

[0015] The assembly, in particular the nesting of the mounting block, is carried out in the general assembly direction, which is substantially perpendicular to the general longitudinal direction of the braking unit and the rotation axis of the rotating braking member.

[0016] However, depending on the overall arrangement of the track braking system relative to the bracket of the vehicle and relative to the rotating braking components of the vehicle, the space in the general assembly direction may be reduced.

[0017] With the system according to the present invention, the mounting block is mechanically fixed in a direction different from the assembly direction.

[0018] For example, the general longitudinal direction of the braking unit is generally horizontal, while the general assembly direction is generally vertical.

[0019] In other words, the fixing of the mounting block can be carried out outside the space that can be allocated in the general assembly direction.

[0020] In particular, the mounting block can be fixed along a direction generally parallel to the rotation axis of the rotating braking member of the vehicle, or along a direction generally parallel to the general extension direction of the braking unit.

[0021] Therefore, the system according to the present invention facilitates the fixing of the braking system to a vehicle, especially when the space between the braking unit and the support (or, in other words, above and below the mounting block) is quite limited.

[0022] The preferred, simple, convenient and economical features of the system according to the present invention are described below.

[0023] The fixing member extends in a fixing direction generally perpendicular to the assembly direction, at least partially passes through the mounting block and is configured to position it relative to the vehicle support and fix it to the latter.

[0024] The mounting block is provided with a through hole that has an opening on a first support surface on one hand and an opening on a second support surface opposite to the first support surface on the other hand, whereby the fixing member is introduced from one or the other of the first support surface and the second support surface in order to assemble the mounting block with the vehicle support.

[0025] The system includes a suspension mechanism disposed between the braking unit and the mounting block, which has a mounting surface different from at least one support surface and is configured to mechanically fix the suspension mechanism in the assembly direction.

[0026] The braking unit includes a connecting device that is mechanically fixed to the suspension mechanism on one hand and mechanically fixed to the braking device on the other hand.

[0029] The fixing interface is provided with an intermediate member that is configured to be mechanically fixed to the vehicle support in the assembly direction on one hand and mechanically fixed to the mounting block through at least one support surface in a direction different from the assembly direction on the other hand.

[0030] The system includes: at least one lining carrier on which at least one lining is mounted; and at least one force transmission link that is mechanically fixed to the intermediate member of the fixing interface on one hand and mechanically fixed to the lining carrier on the other hand.

[0031] The intermediate component is provided with a body which has a central recess, and the mounting block is nested in the central recess. The intermediate component is further provided with at least one additional bearing surface which, for example, protrudes into the central recess to face at least one bearing surface of the mounting block.

[0032] According to a second aspect, the object of the present invention is also to provide a method for assembling and / or disassembling a rail braking system as described above on a rail vehicle, comprising the steps of: nesting and / or separating the mounting block of the fixed interface with the bracket of the vehicle in the assembly direction, and mechanically fixing the mounting block in a direction different from the assembly direction by means of at least one bearing surface and a member for fixing the first bearing surface.

[0033] When the fixed interface of the rail braking system is provided with an intermediate component which is configured to be mechanically fixed to the bracket of the vehicle in the assembly direction on the one hand and to be mechanically fixed to the mounting block in a direction different from the assembly direction by means of at least one bearing surface on the other hand, the method comprises the steps of: assembling the intermediate component to the bracket of the vehicle in the assembly direction, then nesting the mounting block with the intermediate component in the assembly direction, and then mechanically fixing the mounting block in a direction different from the assembly direction.

[0034] The method further comprises the steps of: releasing the mounting block from the intermediate component in a direction different from the assembly direction, then disengaging the mounting block from the intermediate component in the assembly direction, and then disassembling the intermediate component from the bracket of the vehicle.

[0035] According to a third aspect, the object of the present invention is also to provide a rail vehicle having a brake which has at least one brake lining, the rail vehicle comprising at least one rail braking system as described above which is configured to act on at least one rotating braking member of the rail vehicle by means of the at least one brake lining.

[0046] Figure 9 Is similar to Figure 7 A view showing another alternative embodiment of the orbital braking system. Detailed Description

[0047] Figures 1 to 4 Partially shows a railway vehicle 1 equipped with an orbital braking system 2 which is configured to act on a rotating braking member of the railway vehicle 1 by means of a lining 4, here the rotating braking member being formed by a brake disc 3.

[0048] The orbital braking system 2 is mechanically fixed to a support 5 which can be directly or indirectly formed 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.

[0049] Due to the inherent movements of the rail vehicle 1 during the rolling phase and during the braking or brake release phase, the orbital braking system 2 is here mounted "suspended" relative to the support 5.

[0050] The orbital braking system 2 is here mechanically fixed to the railway vehicle 1 only via the support 5 by means of a fixed interface 6 which itself is mechanically fixed on the one hand to a connecting device 7 and on the other hand to a force transmission link 8 of the orbital braking system 2.

[0051] The braking action generates a braking force which is transmitted to the rail vehicle 1 via the support 5, the fixed interface 6, the connecting device 7 and the force transmission link 8.

[0052] Reference Figures 1 to 4, shows a rail braking system 2 with or without a bracket 5 and a brake disc 3 of a vehicle 1. The rail braking system 2 includes a braking unit provided with a braking device 10 and a service and / or parking brake 11 configured to act on the brake disc 3 through the braking device 10.

[0053] The service and / or parking brake 11 generally includes a cylinder 9, here of the pneumatic type.

[0054] The braking device 10 is equipped with a movable lever 12, one end of which is mechanically fixed to the cylinder 9 of the service and / or parking brake 11. The braking device 10 is also equipped with a lining carrier 13, which is mechanically fixed to the respective opposite end of the lever 12 and carries a lining 4.

[0055] The force transmission link 8 is mechanically fixedly connected to the lining carrier 13.

[0056] The movable lever 12 is configured to be actuated by the service and / or parking brake 11.

[0057] The connecting device 7 is part of the braking unit and includes a lower part 14, an upper part 15 connected to the lower part through an intermediate part (not shown), and a pivot shaft 16 around which the lever 12 is movably mounted.

[0058] In the example shown, the lower part 14, the upper part 15 and the intermediate part are formed integrally.

[0059] Therefore, the cylinder 9 of the service and / or parking brake 11 is fixed to the connecting device 7 here through the lever 12 pivotally carried by the connecting device 7.

[0060] The connecting device 7 also includes a fixing part 17. The connecting device 7, the cylinder 9 and the lever 12 are fixed to the fixing interface 6 through the fixing part 17.

[0061] The rail braking system 2 further includes a suspension mechanism 18 disposed between the fixing interface 6 and the connecting device 7. The brake cylinder 9 is connected to the suspension mechanism 18 through the lever 12.

[0062] In the example shown, the braking unit extends in a general longitudinal direction L substantially orthogonal to the rotation axis R of the brake disc 3.

[0063] Furthermore, the braking system 2 is assembled to the bracket 5 of the vehicle 1 through the fixing interface 6 in an assembly direction A substantially perpendicular to the general longitudinal direction L and the rotation axis R here.

[0064] For example, the general longitudinal direction L is generally horizontal, while the assembly direction A is generally vertical.

[0065] The fixing interface 6 is provided with a mounting block 20 and an intermediate member 21 (also called an anchoring member) here.

[0066] In the example shown, the fixed interface 6 is configured such that the mounting block 20 is directly mechanically fixed to the suspension mechanism 18 on the one hand and directly mechanically fixed to the intermediate member 21 on the other hand, while the intermediate member 21 is in turn configured to be directly mechanically fixed to the bracket 5 of the vehicle 1.

[0067] In particular, the mounting block 20 and the intermediate member 21 are configured to be assembled by nesting in the assembly direction A and are mechanically fixed together in a direction different from the assembly direction A.

[0068] The intermediate member 21 is provided with a first body 22, an extension 23 projects from the first body 22, and the force transmission link 8 is assembled to the extension 23.

[0069] The first body 22 has a central recess 24 in which the mounting block 20 is nested, and the first body 22 has two walls forming "complementary" bearing surfaces 25, each wall protruding into the central recess 24 and facing each other.

[0070] The first body 22 further has a plurality of first fixing holes leading to the central recess 24, including a first positioning fixing hole 27 and a first fixing hole 26 arranged only through the complementary bearing surface 25 here.

[0071] The first fixing holes 26, 27 are all oriented in a direction different from the assembly direction A here.

[0072] The first body 22 further has other fixing holes 29, the fixing holes 29 are arranged to penetrate the first body 22, are oriented in the assembly direction A, and are provided to receive fixing screws 28 to mechanically fix the intermediate member 21 to the bracket 5 of the vehicle 1.

[0073] The mounting block 20 is provided with a second body 30, the second body 30 defines two bearing surfaces 31 here, also referred to as the first bearing surface and the second bearing surface, and a plurality of second fixing holes are provided in the bearing surfaces 31, including a second positioning fixing hole 33 and a second fixing hole 31.

[0074] The second body 30 of the mounting block 20 is nested in the central recess 24 of the first body 22 of the intermediate member 21 such that the complementary bearing surfaces 25 face and are adjacent to the bearing surfaces 31 respectively, and the track braking system 2 includes a member for fixing the bearing surfaces 31 to the complementary bearing surfaces 25. In the example shown, it includes a positioning fixing member 35 passing through at least one of the first positioning fixing hole 27 and the second positioning fixing hole 33, and a fixing member 34 passing through at least some of the first fixing hole 26 and the second fixing hole 32.

[0075] Therefore, the fixing member extends in a direction different from the assembly direction A.

[0076] Furthermore, the support surface 31 and the complementary support surface 25 are generally flat here and are arranged to form a flat support between the mounting block 20 and the intermediate member 21.

[0077] Figure 3 and Figure 4 A method of assembling the track braking system 2 to the bracket 5 of the vehicle 1 via the fixed interface 6 is shown.

[0078] In Figure 3 the intermediate member 21 together with the force transmission link 8 is mechanically fixed to the bracket 5 by means of fixing screws 28 inserted along the assembly direction.

[0079] It is particularly easy to access here in the absence of the rest of the track braking system 2.

[0080] In other words, the intermediate member 21 is mounted to the bracket 5 separately.

[0081] The rest of the track braking system 2, in particular including the already assembled cylinder 9, lever 12, connecting device 7, suspension mechanism 18 and mounting block 20, can then be brought closer to the intermediate member 21 along the assembly direction.

[0082] Figure 4 In

[0083] the mounting block 20 is nested within the intermediate member 21 such that the support surface is opposite and adjacent to the complementary support surface, then the positioning fixture 35 is passed through one of the first positioning fixing holes 27 and the second positioning fixing hole 33, and then the fixture 34 is passed through the first fixing hole 26 and the second fixing hole 32.

[0084] More generally, the method of assembling and / or disassembling the track braking system 2 includes the following steps: nesting and / or disengaging the mounting block 20 from the support 5 and the fixed interface 6 along the assembly direction, and mechanically fixing the mounting block 20 in a direction different from the assembly direction.

[0085] When the fixed interface 6 is provided with the intermediate member 21 as described above, the method first includes the following steps: mounting the intermediate member 21 to the bracket 5 along the assembly direction, then nesting the mounting block 20 with the intermediate member 21 along the assembly direction, and then mechanically fixing the mounting block 20 in a direction different from the assembly direction.

[0086] For disassembly, the method further comprises the steps of: releasing the mounting block 20 from the intermediate member 21 in a direction different from the assembly direction, then removing the mounting block 20 from the intermediate member 21 in the assembly direction, and then removing the intermediate member 21 from the bracket 5.

[0087] Figure 5 Yes Figure 4 is a detailed view showing the attachment portion 17 of the suspension mechanism 18 to the upper portion 14 of the connecting device 7, and the assembly of the mounting block 20 and the intermediate member 21.

[0088] Figure 6 and Figure 7 are respectively Figure 5 and Figure 6 cross-sections taken at A-A and B-B in

[0089] 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 member such that the complementary bearing surfaces 25 face the bearing surface 31 and are adjacent to the bearing surface 31.

[0090] Members 35, 34 for fixing the bearing surface 31 to the complementary bearing surface 25 pass through one of the first positioning and fixing holes 27 and the second positioning and fixing hole 33, and also through at least some of the first fixing hole 26 and the second fixing hole 32.

[0091] Thus, the fixing member extends in a direction different from the assembly direction.

[0092] In addition, the bearing surface 31 and the complementary bearing surface 25 form a planar bearing between the mounting block and the intermediate member.

[0093] In other words, the fixing members 34, 35 extend in a fixing direction generally perpendicular to the assembly direction, pass at least partially through the mounting block and are configured to position the mounting block relative to the bracket 5 of the vehicle 1 and attach the mounting block to the bracket 5 through the intermediate member.

[0094] In particular, the fixing of the mounting block 20 can be carried out in a direction generally parallel to the axis of rotation of the disc.

[0095] The fixing member can be inserted from one or the other bearing surface 31 for assembling the mounting block.

[0096] Figure 7 More particularly shows the fixing of the suspension mechanism 18 to the mounting block 20 and the attachment portion 17 of the upper portion 14 of the connecting device 7.

[0097] The track braking system 2 includes complementary fixing screws 45 which are inserted into holes 48 provided in the mounting surface 47 of the mounting block 20, the mounting surface being different from the bearing surface 31.

[0098] In the example shown, the suspension mechanism 18 has a first damping buffer 49 and a second damping buffer 50 mounted on both sides of the attachment portion 17.

[0099] Complementary holes are formed such that the complementary fixing screw 45 passes through the damping buffer 50, the attachment portion 17, and the damping buffer 49, and then is inserted into the tapped hole 48.

[0100] Washers can be installed in the complementary holes to limit the tightening of the complementary fixing screw 45 and the deformation of the damping buffers 49 and 50.

[0101] Figure 8 An alternative embodiment of the system is shown, where the same reference numerals as above are used for similar elements, but the number 100 is added. The mounting block 120 is provided with at least one guiding and / or anti-misalignment member, which is formed here by a notch 150 provided in the second body 130 and in particular in the bearing surface, while a complementary projection 155 is formed on the complementary bearing surface 125 of the intermediate member 121.

[0102] More generally, at least one guiding and / or anti-misalignment member is formed by a notch or a projection arranged in at least one bearing surface, and is configured to cooperate with a complementary projection or a complementary notch of the complementary bearing surface respectively.

[0103] Figure 9 An alternative embodiment of the system is shown, where the same reference numerals as above are used for similar elements, but the number 200 is added. The suspension mechanism 218 is different from the above-mentioned suspension mechanism in that the suspension mechanism 218 is provided with a plurality of cylinders 260, which are suspended and mounted in the second body 230 of the mounting block 220, and the attachment portion 217 of the connecting device 207 is directly fixed to the cylinders 260 through the mounting surface 247.

[0104] In the above-mentioned track braking system 2, the assembly, especially the nesting of the mounting block 20, is carried out in a general assembly direction that is substantially perpendicular to the longitudinal general direction and the rotation axis of the rotating braking component. However, depending on the overall arrangement of the track braking system relative to the vehicle bracket and relative to the brake disc, the space in the general assembly direction may be reduced. With the system according to the present invention, the mechanical fixing of the mounting block is carried out in a direction different from the assembly direction. In other words, the fixing of the mounting block can be carried out outside the space allocated in the general assembly direction. In particular, the fixing of the mounting block can be carried out in a direction substantially parallel to the rotation axis of the rotating braking component of the vehicle, or in a direction substantially parallel to the general extension direction of the braking unit. Therefore, the system according to the present invention helps to fix the braking system to the vehicle, especially when the space between the braking unit and the bracket (in other words, above and below the mounting block) is quite limited.

[0105] Alternative solutions not shown are given below.

[0106] The intermediate member may be integrally formed with the bracket.

[0107] There may be more or fewer members for fixing the mounting block to the intermediate member and / or the bracket.

[0108] The fixing member extends in a fixing direction generally perpendicular to the assembly direction, and in particular the fixing direction is generally parallel to the overall extension direction of the brake unit rather than generally parallel to the rotation axis of the disc.

[0109] The suspension mechanism includes only one suspension cylinder, with or without suspension links.

[0110] The track braking system has no suspension mechanism.

[0111] The service and / or parking brake may be electromechanical, hydraulic, electric or manual, rather than pneumatic.

[0112] More generally, the present invention is not limited to the examples described and shown.
