Description
- This application is a national stage entry of International Patent Application No. PCT/EP2020/070888 (filed 23 Jul. 2020), which claims priority to French Patent Application No. 1908510 (filed 26 Jul. 2019), French Patent Application No. 1908512 (filed 26 Jul. 2019), and French Patent Application No. 1911666 (filed 18 Oct. 2019), the entire disclosures of which are incorporated herein by reference.
- The inventive subject matter concerns the field of vehicle brakes. More particularly, the inventive subject matter concerns a braking system for a rail vehicle having brakes with at least one lining, provided with a braking linkage and with a service brake and/or parking brake configured to act on the braking members of the vehicle (for example, such as brake disks) via the braking linkage.
- The vehicles referred to as having brakes with at least one lining are generally equipped with braking systems having service brake and/or parking brake cylinders, comprising a piston movable under the effect of a fluid under pressure. Movement of the piston actuates a braking linkage and drives a braking action (such as the clamping of a brake disk) by the lining of that linkage.
- Such a braking system is mounted on the vehicle to be in contact with the brake disks or the wheels. In particular, the braking system may be mechanically connected to a bogie, to an axle fastened to the bogie, or to another device like the drive motor or the gearbox also mounted on the bogie.
- The braking action gives rise to braking forces which may be transmitted to the mounting to which the braking system is mechanically connected via the braking linkage. These forces may generate deformations, or at least movements, of the braking linkage relative to the brake disk of the vehicle, thereby giving rise to irregular wear of the lining.
- The inventive subject matter concerns a braking system for a vehicle having brakes with at least one lining. The braking system includes an improved braking linkage, while being simple, convenient and economical.
- According to a first aspect, the inventive subject matter relates to a rail vehicle braking system, comprising a braking linkage and a service brake and/or parking brake configured to act on at least one braking member of the rail vehicle via the braking linkage. The linkage is provided with at least one device having at least one lining mounting and at least one lining mechanically connected to the at least one lining mounting. The device comprises at least two bearing regions for bearing on the at least one braking member and at least one set back region located between the two the bearing regions.
- In other words, the device of the braking linkage (which contacts the braking member of the vehicle, for example in particular a brake disk) is provided with a bearing surface referred to as being discontinuous, with only the bearing regions which enable forces to be transmitted to the brake disk. This enables the transmission of the forces to the brake disk to be distributed. In particular, the bearing regions and the set back regions can be provided on the braking linkage device according to the type of braking system and/or the use of the rail vehicle. For example, the arrangement of the braking linkage of which the form, the arrangement and/or the materials of the lining mounting and/or of the linings, the fact of whether the braking linkage is a parking brake or else a service brake, the type of vehicle (tram, subway train, high-speed train, etc.) and/or the load of the vehicle, the journey made by the vehicle, and/or the type of braking member (diameter, thickness, material of the disk) may be parameters for determining the bearing and set back regions.
- The placing of the bearing and set back regions may thus be predetermined, for example by trials in advance. Such bearing and set back regions are configured to distribute the transmission of the forces over the braking member. These regions are quite different from any regions for fastening the linings onto the lining mounting, these latter not being configured to distribute the transmission of the forces over the braking member.
- Features according to the inventive subject matter that are preferred, simple, convenient and economical are presented below.
- The system may comprise at least two linings mechanically connected to the lining mounting, at least one the bearing region being located facing opposite the respective lining. The at least two bearing regions and the at least one set back region may be provided on the at least one lining mounting. This, in particular, enables so-called standard linings to be used. The at least two bearing regions and the at least one set back region may be provided on the at least one lining.
- The device may comprise a plurality of the bearing regions between which are formed the set back regions. The at least one lining mounting and/or the at least one lining may have a longitudinal general orientation and a transverse general orientation, with the bearing and set back regions succeeding each other in the longitudinal general orientation. At least one the bearing and/or set back region may extend fully or only partly along the transverse general orientation. The bearing and set back regions are provided substantially symmetrically relative to a transverse central axis of the device. This axis may for example constitute a median axis of the braking member of the rail vehicle.
- The braking linkage may be provided with at least one lever extending from the service brake and/or parking brake to the device. The at least one lever to may be mechanically connected to the at least one lining mounting on an attachment region thereof which is located away from the at least one lining and which is at most 35 millimeters (mm) from a transverse central axis of the device.
- The attachment region may be located between approximately 0 and 35 mm from the transverse central axis of the device. The attachment region may extend in a longitudinal general orientation of the device and over a length comprised between approximately 15 mm and approximately 75 mm. The attachment region may extend uninterruptedly on opposite sides of the transverse central axis of the device. The at least one attachment region may extend interruptedly on opposite sides of the transverse central axis of the device.
- The system may comprise at least one force transmission link member mechanically connected at a first end to a mounting of the vehicle and at a second end, which is an opposite end to the first end, to the at least one lining mounting, in immediate proximity to the attachment region of the at least one lever. The at least one force transmission link member may be substantially L-shaped, or S-shaped. The at least one force transmission link member may extend substantially in a same plane as that in which extends the at least one lever. The at least one force transmission link member may be mechanically connected by pivotal connections respectively to the vehicle mounting and to the at least one lining mounting. The at least one force transmission link member may have an added functional clearance at its second end where it is connected to the at least one lining mounting. The at least one force transmission link member may be connected via a rotary joint to the at least one lining mounting. The at least one force transmission link member may be connected to the at least one lining mounting via a pivotal shaft pivoting in an aperture of considerably greater diameter than that of the pivotal shaft, or in an oblong aperture.
- According to a second aspect, the inventive subject matter also relates to a rail vehicle comprising at least one braking member (for example in particular a brake disk) and at least one rail vehicle braking system as described above, which is configured to act on the at least one braking member.
- The disclosure of the inventive subject matter will now be continued with the description of embodiments, given below by way of illustrative and non-limiting examples, with reference to the accompanying drawings.

FIG. 1 diagrammatically represents avehicle braking system 1 for a vehicle having a brake with linings. This is a rail vehicle braking system structurally of the type described in Europeanpatent application EP 2 826 684. Thevehicle braking system 1 comprises abody 2 forming a cylinder of both aservice brake 6 and aparking brake 7, a control and actuation unit 3 configured to manage the operation of theservice brake 6 and of theparking brake 7, a conveyance network of pneumatic pipes that is connected to thebody 2 and to the control and actuation unit 3, and abraking linkage 4 mechanically linked to thebody 2. - The
body 2 has the form of a generally closed envelope. Theservice brake 6 comprises aservice brake piston 8 movable relative to thebody 2 in a first axial direction, and athrust rod 9 also movable relative to thebody 2 in a second axial direction perpendicular to the first axial direction. Together with thebody 2 thebraking piston 8 delimits a servicebrake pressure chamber 13. - The
braking piston 8 has two sides including afirst side 17 configured to act on thebraking linkage 4 via thethrust rod 9 and asecond side 18 which is an opposite side to thefirst side 17 and which is turned towards the servicebrake pressure chamber 13. Theservice brake 6 further comprises a notchedrod 21 fastened to thesecond side 18 of thebraking piston 8. This notchedrod 21 extends longitudinally in the first axial direction. Thebraking piston 8 is configured to move in thebody 2 while maintaining the servicebrake pressure chamber 13 relatively fluid-tight thanks to amembrane 14, for example formed by a seal, disposed between thatbraking piston 8 and inside edges of thebody 2. - The
service brake 6 may further comprise awedge part 10 fastened to thefirst side 17 of thebraking piston 8. Thiswedge part 10 may have a triangular section and be configured to cooperate with a set of rolling bearing stops 11, of which one of the rolling bearing stops may be linked to thebody 2 while the other of the rolling bearing stops may be linked to thethrust rod 9. Thisthrust rod 9 may be provided with a wear adjuster configured to compensate for the wear of the linings of thebrake 5 in order to avoid reduction of the braking force by excessive play (further to wear of the linings). - The
service brake 6 may comprise aspring 12 disposed around thethrust rod 9, between the rolling bearing stop which is linked to the latter and an inside edge of thebody 2. Thisspring 12 is configured to return the stop which is linked to thethrust rod 9 against thewedge part 10. Theservice brake 6 may comprise afirst aperture 15 formed in thebody 2 and configured to enable the movement of thethrust rod 9 through thatfirst aperture 15. Theservice brake 6 may comprise asecond aperture 16 formed in thebody 2 and opening into the servicebrake pressure chamber 13. The servicebrake pressure chamber 13 is connected here by afirst supply pipe 72 of the conveyance network of pneumatic pipes, more generally called brake pipe, which pipe is connected at the location of thatsecond aperture 16, to a source of supply of pneumatic pressure agents (not shown). - The
body 2 comprises acavity 27 situated against the servicebrake pressure chamber 13 and in which is disposed theparking brake 7. Theparking brake 7 comprises a blocking device formed by a blockingfinger 20 movable relative to thebody 2 and extending in the second axial direction. Theparking brake 7 comprises aholding piston 23 movable relative to thebody 2 and with the latter delimiting a parkingbrake pressure chamber 25. This holdingpiston 23 has two sides, respectively afirst side 31 on which is attached the blockingfinger 20 and which is turned towards the parkingbrake pressure chamber 25, and asecond side 32 which is an opposite side to the first side. - The
parking brake 7 comprises aspring member 24 disposed between thebody 2 and thesecond side 32 of the holdingpiston 23. Thisspring member 24 is configured to act on that holdingpiston 23 and therefore on the blockingfinger 20. The holdingpiston 23 and thespring member 24 may form a movable actuating device of theparking brake 7. The holdingpiston 23 is configured to move in thebody 2 while maintaining the parkingbrake pressure chamber 25 relatively fluid-tight thanks to a membrane disposed between that holdingpiston 23 and the inside edges of thebody 2. Theparking brake 7 comprises a third aperture (not shown) formed in thebody 2 and opening both into the parkingbrake pressure chamber 25 and into the servicebrake pressure chamber 13, which third aperture is configured to enable the movement of the blockingfinger 20 through that third aperture. The relative sealing between the parkingbrake pressure chamber 25 and the servicebrake pressure chamber 13 is ensured by the presence of aseal 33 disposed at the interface between that third aperture and the blockingfinger 20. - The
parking brake 7 comprises afourth aperture 28 formed in thebody 2 and opening into the parkingbrake pressure chamber 25. The parkingbrake pressure chamber 25 may be connected here by asecond supply pipe 71 of the conveyance network of pneumatic pipes, also called parking brake pipe, which is connected at the location of thatfourth aperture 28, to the source of supply of pneumatic pressure agents 73 (visible inFIG. 2 ) via the unit 3. - The
parking brake 7 comprises an unlockingpart 29 to deactivate theparking brake 7. The unlockingpart 29 may for example be attached on thesecond side 32 of the holdingpiston 23 and open to the outside of thebody 2 through a fifth aperture (not shown) provided in thatbody 2 and opening into thecavity 27. The unlockingpart 29 is accessible to be manipulated from outside thebody 2 if required. The unlockingpart 29 may be connected to an indicator device provided to indicate a state of theparking brake 7 and/or a state of theservice brake 6. In particular, the unlockingpart 29 may be coupled to a switch mechanically connected to thatpart 29 and having a first position and a second position selected according to the position of the unlockingpart 29. - The
service brake 6 is disposed in thebody 2 and is configured to act on one ormore braking members 35 of the rail vehicle via thebraking linkage 4. The brakingmember 35 of the vehicle may comprise a brake disk (here viewed from above) mounted for example on arail vehicle axle 36, or directly on the wheel to brake. - The
braking linkage 4 is provided with adevice 5 having linings which is provided to apply forces on thebrake disk 35 when thelinkage 4 is actuated. Thisdevice 5 here comprises twolining mountings 37 to each of which linings 38 are mechanically connected. In particular, twolinings 38 may be mounted on each lining mounting 37. Each lining 38 is provided to be applied to contact thedisk 35 to reduce its rotational speed and therefore that of the wheel to brake. Thebraking linkage 4 here compriseslevers 40, for example that are substantially deformable. In the described example, eachlever 40 is provided with an upper portion and with a lower portion which are joined and which extend from the service and parking brake to thedevice 5. Each portion of thelevers 40 may be jointed to acentral connector 41 via two pivots 42. The upper portion of eachlever 40 may be linked by a first end to a respective joint 44, 45. - The
braking linkage 4 may receive thebody 2 between the upper portions of thedeformable levers 40, at the location of thejoints body 2 may be rotatably mounted on the joint 44 which is attached to an end of thethrust rod 9 whereas it may have a fixed mounting to the joint 45, which is directly attached to thatbody 2. The lower portion of eachlever 40 may be linked, at a second end which is an opposite end to its first end, to one of thelining mountings 37 at the location of anattachment region 39 provided on the latter and which faces away from thelinings 37. Thebraking linkage 4 may comprise afirst fastening member 43 joined to thecentral connector 41 for the mounting of thatbraking linkage 4 on the rail vehicle; in order for thelining mountings 37 to be situated on respective opposite sides of the brake disk 35 (or of the wheel of the rail vehicle). The coming towards each other of thejoints lining mountings 37 to be moved apart from each other and that conversely, the separation of thosejoints lining mountings 37 to be to clamped onto the brake disk 35 (or onto the rail vehicle wheel). - The control and actuation unit 3 is connected to the service
brake pressure chamber 13 via thefirst supply pipe 72 to which it is connected. This unit 3 is connected to the parkingbrake pressure chamber 25 via thesecond supply pipe 71 to which it is connected. This unit 3 is supplied with pneumatic agents by amain pipe 70 which passes generally along the rail vehicle. The unit 3 comprises system members (not shown inFIG. 1 ) which are configured to receive and process representational information relative for example to operational settings of the rail vehicle, by a first electrical and/or pneumatic and/or manual type channel, denoted 50 inFIG. 1 . - These system members are furthermore configured to receive and process representational information relating to parameters of use of the rail vehicle, by a second channel of electrical and/or pneumatic and/or manual type, which is denoted 60 in
FIG. 1 . These system members may for example be formed by pneumatic relays and/or solenoids and/or pressure switches and/or sensors and/or pressure reducing valves and/or electrical relays and/or electronic cards and/or central processing units or microprocessors, and/or random access memory components comprising registers adapted to record variables of the parameters created and modified during the execution of programs, and/or communication interfaces configured to send and receive data, and/or internal storage members, such as hard disks, able in particular to store the executable code of programs enabling the management of the service andparking brakes -
FIG. 2 very diagrammatically shows thevehicle 48 provided with an axle forming a mounting 49 to which thesystem 1 is mechanically connected, via for example asecond fastening member 47 which links thebody 2 to the mounting 49. Thesystem 1 may comprise at least one forcetransmission link member 50 also mechanically connected at a first end to the mounting 49 of thevehicle 48 and at a second end, which is an opposite end to said first end, to said to the lining mounting 37, in immediate proximity to saidattachment region 39 of thelever 40. The lining mounting 37 here faces opposite a face of thedisk 35 mounted on itsaxle shaft 36 of thevehicle 48. - A description will now be given in more detail, with reference to
FIGS. 3 to 16 , of thedevice 5 and of the arrangement of thelevers 40 in relation to thedevice 5, in accordance with several embodiments.FIGS. 3 to 6 illustrate a first version of a first embodiment. Thedevice 5 faces opposite thebrake disk 35. Thedevice 5, comprising a lining mounting 37 and lining 38, has a longitudinal general orientation and a transverse general orientation. A longitudinalcentral axis 52 and a transversecentral axis 51 are illustrated. They correspond to the median axes of thebrake disk 35 and, in the position illustrated inFIG. 3 , respectively the transversecentral axis 51 furthermore corresponds to a transverse central axis of the device 3. - The
lever 40 is mechanically connected to the lining mounting 37 via theattachment regions 39. Theattachment regions 39 are located at most at approximately 35 mm from the transversecentral axis 51 of thedevice 5. This means that the distances E shown inFIG. 3 are each at most equal to 35 mm. Here, theattachment regions 39 are located on opposite sides of the transversecentral axis 51 and thus, at most, extend over approximately 70 mm in the direction of the longitudinal general orientation. More generally, the attachment region orregions 39 may be located between approximately 0 and approximately 35 mm from the transversecentral axis 51 and may extend in a longitudinal general orientation and over a length comprised between approximately 15 mm and approximately 70 mm. - In the described example, the
attachment regions 39 extend interruptedly on opposite sides of the transversecentral axis 51. In other words, theattachment regions 39 are distinct. As a variant, the attachment region may extend uninterruptedly on opposite sides of the transversecentral axis 51. A longitudinalforce application axis 53 is illustrated in fine chain line, while alongitudinal holding axis 54 is illustrated in thick chain line. - The longitudinal
force application axis 53 is the one passing through theattachment regions 39 of the lining mounting 37, which regions enable the mechanical connection of thelevers 40, while thelongitudinal holding axis 54 is slightly offset relative to the longitudinalforce application axis 53 and corresponds to the region for fastening thelinings 53 onto the lining mounting 38. - The loads applied by the
lever 40 of thebraking linkage 4 on thedevice 5 of thatlinkage 4 to place it in contact with thebrake disk 35 are thus substantially centered on the lining mounting 37. Since theattachment regions 39 of thelever 40 on the lining mounting 37 are close to the centraltransverse axis 51, this enables thelining mountings 37 to have a degree of freedom when it transmits forces to thebrake disk 35. In the described example, thedevice 5 comprises at least two bearingregions 60 on thebrake disk 35 and at least one set backregion 61 located between the two bearingregions 60. - More generally, the device may comprise a plurality of bearing regions between which are formed set back regions. The bearing and set back
regions device 5. The twobearing regions 60 and the set backregion 61 are provided here on a face of the lining mounting 37, which is an opposite face to that on which are formed theattachment regions 39. Each of the two bearingregions 60 is provided here so as to be located facing opposite arespective lining 38. - This is shown in
FIGS. 6 and 7 in which can be seen the bearingregions 60 provided on the lining mounting 37 and in which can also be seen favoredcontact regions 65 provided on thelinings 38, which respectively correspond to thebearing regions 60. It will be noted that the bearing regions may be formed by protrusions on the lining mountings and/or that the set back region may be formed by recesses in the lining mountings. The bearing regions and the set back regions are thus located in planes that are offset. In the described example, the bearingregions 60 and the set backregion 61 extend fully along the transverse general orientation of thedevice 5. - Furthermore, the bearing
regions 60 and the set backregion 61 are formed here substantially symmetrically relative to the transversecentral axis 51. Thedevice 5 and thebraking linkage 4 which comes into contact with thebrake disk 35 is thus provided with a bearing surface referred to as discontinuous, with only the bearingregions 60 enabling forces to be transmitted to thebrake disk 35. This enables the transmission of the forces to thebrake disk 35 to be distributed. -
FIGS. 7 to 9 illustrate a second version. The difference compared with the preceding version is that the bearingregions 60 are closer to each other and to the transversecentral axis 51, and the set backregion 61 is more limited. This results in the favoredcontact regions 65 provided on thelinings 38 and which respectively correspond to thebearing regions 60 are also closer to each other and to the transversecentral axis 51. Theattachment regions 39 are identical to those described above. -
FIGS. 10 and 11 are similar views to those ofFIGS. 8 and 9 , except that the bearingregions 60 and the set backregion 61 do not extend fully along the transverse general orientation of thedevice 5. On the contrary, the bearingregions 60 and the set backregion 61 extend only partly along the transverse general orientation of thedevice 5. The same thus applies for the favoredcontact regions 65 provided on thelinings 38 and which respectively correspond to thebearing regions 60. In the example described, the bearingregions 60 and thus the favoredcontact regions 65 are situated rather towards the outside of thebrake disk 35. -
FIGS. 12 and 13 are similar views to those ofFIGS. 10 and 11 , with the bearingregions 60 and the set backregion 61 extending only partly along the transverse general orientation of thedevice 5, and rather towards the inside of thebrake disk 35. The same thus applies for the favoredcontact regions 65 provided on thelinings 38 and which respectively correspond to thebearing regions 60 and which are rather towards the inside of thebrake disk 35. In the example described, the bearingregions 60 and thus the favoredcontact regions 65 are situated rather towards the outside of thebrake disk 35. -
FIGS. 14 to 17 illustrate a first version of a second embodiment. Thedevice 5 differs from those described above in that thelever 40 is mechanically connected to the lining mounting 37 via asingle attachment region 39. Theattachment region 39 is at the location of the transversecentral axis 51 of thedevice 5 and extends slightly on opposite sides of thataxis 51. For example, the attachment region extends only approximately 10 mm to approximately 20 mm on opposite sides of the transversecentral axis 51. This means that the distance E shown inFIG. 10 is at most equal to approximately 40 mm, in the direction of the longitudinal general orientation. More generally, such a single attachment region may extend in a longitudinal general orientation and over a length comprised between approximately 15 mm and approximately 70 mm. Thesingle attachment region 39 here extends uninterruptedly on opposite sides of the transversecentral axis 51. - The loads applied by the
lever 40 of thebraking linkage 4 on thedevice 5 of thatlinkage 4 to place it in contact with thebrake disk 35 are thus substantially centered on the lining mounting 37. Since theattachment region 39 of thelever 40 on the lining mounting 37 is at the location of the centraltransverse axis 51, this enables thelining mountings 37 to have a degree of freedom when it transmits forces to thebrake disk 35. In the described example, thedevice 5 comprises at least two bearingregions 60 on thebrake disk 35 and at least one set backregion 61 located between the two bearingregions 60. The bearing and set backregions device 5 and are identical to that of the device illustrated inFIGS. 3 to 6 . - The two
bearing regions 60 and the set backregion 61 are provided here on a face of the lining mounting 37, which is an opposite face to that on which are formed theattachment regions 39, and each of the two bearingregions 60 is provided here so as to be located facing opposite arespective lining 38.Favored contact regions 65 are thus provided on thelinings 38, which respectively correspond to thebearing regions 60. The bearingregions 60 and the set backregion 61 extend fully along the transverse general orientation of thedevice 5, and are provided here substantially symmetrically relative to the transversecentral axis 51. - The
device 5 and thebraking linkage 4 which comes into contact with thebrake disk 35 is thus provided with a bearing surface referred to as discontinuous, with only the bearingregions 60 enabling forces to be transmitted to thebrake disk 35. This enables the transmission of the forces to thebrake disk 35 to be distributed. -
FIG. 18 is a similar view to that ofFIG. 14 , with addition of the forcetransmission link member 50 visible very diagrammatically inFIG. 2 . The forcetransmission link member 50 is mechanically connected at its first end to the mounting 49 of the vehicle and at a second end, which is an opposite end to its first end, to the lining mounting 37, and in immediate proximity to thesingle attachment region 39 of thelever 40 on that same lining mounting 37. The forcetransmission link member 50 may be mechanically connected bypivotal connections attachment regions 39 of thelever 40 on the lining mounting 37 are close to and/or are centered on the transversecentral axis 51 of thedevice 5, thepivotal connection 75 which connects the forcetransmission link member 50 to the lining mounting 37 is also at a location close to that same transversecentral axis 51, thereby limiting the distance D shown inFIGS. 17 to 19 . This in particular makes it possible to have an especiallycompact system 1. -
FIG. 19 shows the same forcetransmission link member 50 mechanically connected to a lining mounting 37 of adevice 5 similar to that described with reference toFIG. 15 , with bearingregions 60 and a set backregion 61 provided on the lining mounting 37, and with asingle attachment region 39 of thelever 40 on the lining mounting 37. -
FIG. 20 shows very diagrammatically the forcetransmission link member 50 mechanically connected to the lining mounting 37 of adevice 5 quite close to those described above, but of which thebearing region 60 is formed here with steps. In other words, thebearing region 60 comprisesdifferent bearing portions region 61. In particular, the bearingportion 63 forms what is designated an augmented-bearing region. - In variants not illustrated, the lining-mounting may comprise one or more set back regions extending for approximately 100 mm to approximately 300 mm from the transverse central axis of said device. The set back region or regions may be formed by cavities having a depth comprised for example between approximately 0.1 mm and approximately 0.5 mm.
- According to a first example embodiment, the lining-mounting can comprise a single set back region extending for approximately 180 mm (or for 90 mm on opposite sides of the transverse axis), and having a cavity of approximately 0.2 mm; the rest of the lining-mounting overall forming one or more bearing regions.
- According to a second example embodiment, the lining-mounting can comprise a first set back region extending for approximately 120 mm (or for 60 mm on opposite sides of the transverse axis), and having a cavity of approximately 0.3 mm, next the second set back regions either do or do not immediately succeed the first set back region, each extending for approximately 60 mm and having a cavity of approximately 0.15 mm; the rest of the lining-mounting overall forming one or more bearing regions.
- According to a third example embodiment, the lining-mounting can comprise a first set back region extending for approximately 120 mm (or for 60 mm on opposite sides of the transverse axis), and having a cavity of approximately 0.35 mm, next the second set back regions either do or do not immediately succeed the first set back region, each extending for approximately 60 mm and having a cavity of approximately 0.2 mm; the rest of the lining-mounting overall forming one or more bearing regions.
- Such arrangements of the set back regions make it possible to distribute the transmission of the forces over the braking member.
- Other variants not illustrated are described below.
- The force transmission link member may have an added functional clearance at least at its second end where it is connected to the lining mounting by its pivotal connection. In particular, the force transmission link member may be connected via a rotary joint to the lining mounting or instead via a pivotal shaft pivoting in an aperture of considerably greater diameter than that of the pivotal shaft, or in an oblong aperture. For example, an axis of the force transmission link member may be angularly offset to enable the device, including the lining mounting and the linings, to self-tilt to maintain optimum application of the braking force while making it possible to send the forces to the vehicle mounting. This in addition to makes it possible to limit the wear of the
linings 38 obliquely, despite the deformations which for example thebrake disk 35 may undergo. - The force transmission link member may be substantially L-shaped, or S-shaped, with the pivotal connections being respectively to the mounting of the vehicle and to the lining mounting 37. The force transmission link member may extend substantially in a same plane as that in which said lever extends. Such an arrangement is particularly compact and enables a maximum travel of the lining mounting relative to the mounting, thanks the L-shaped or S-shaped force transmission link member which does not cause hindrance by the movement of the lining mounting.
- The bearing regions and/or the set back region may be provided in the linings rather than in the lining mountings. Some bearing and/or set back regions may extend fully along the transverse general orientation, while other of these regions may extend only partly. The bearing and set back regions are not provided substantially symmetrically relative to the transverse central axis. A single lining, rather than two linings, is mounted on each of the lining mountings, or, on the contrary, more than two linings are mounted on each of the lining mountings.
- The force transmission link member may be mechanically connected to the vehicle mounting, directly or by an intermediate connecting part. The force transmission link member may be H-shaped, or Y-shaped, it being possible for this to be inverted, or for instance I-shaped, rather than L-shaped or S-shaped.
- The rail vehicle braking system may be different from that described above in that it may concern only a service brake, or concern only a parking brake, and in that the mechanism may have springs as has for example been described in
document EP 2 154 040. - More generally, the invention is not limited to the examples described and illustrated.
