Definitions

  • the present invention aims to create a bogie which allows to have a low integral floor and which is of a low manufacturing cost.
  • the bogie must also provide high comfort for passengers and have a small wheelbase, great robustness, reliability and security.
  • the bogie according to the invention is characterized in that the non-rotating axles, are U-shaped with a lower middle part and two lateral branches on which the wheels are rotatably mounted, by the fact that each lateral branch comprises at least one portion arranged so as to carry at least one primary suspension member, by the fact that the chassis comprises at least a lower middle part and higher lateral portions intended to bear on the primary suspension members so as to be suspended on the two axles, by the fact that the bogie comprises a dancer cross member having two higher lateral branches and a lower middle part, the two lateral branches each resting on a secondary suspension member arranged on each side of the chassis, the lower middle part of the dancer crosspiece carrying said pivoting device arranged so as to obtain a bogie swivel for vehicle with low central floor.
  • the aforementioned characteristics make it possible to obtain a motorized vehicle with an integral low floor and a very reduced height on the ground.
  • the construction of the bogie is simple and at a competitive cost price. Its center of gravity is very low, contributing to high security, reliability and solidity. Due to a dual primary and secondary suspension system, comfort for passengers is excellent. The weight of the unsprung masses is very low, resulting in increased robustness and comfort.
  • the lower middle part of the chassis is constituted by at least two crosspieces separated by a central transverse space and by the fact that the lower middle part of the dancer crosspiece is arranged at least partially in this central transverse space.
  • each of the primary suspension members is constituted by two elements with conical surfaces fitted one inside the other and between which is arranged at least one elastic annular part.
  • the movement guidance between the chassis and the axles is improved, resulting in greater safety and robustness.
  • the bogie may include lower connecting elements between each axle and the chassis constituted by four connecting rods connecting the lower middle part of each axle to the chassis and having an oblique orientation relative to the axles so as to form a rhombus therebetween.
  • the lateral branches of each axle can be connected to the chassis by a rod with a longitudinal orientation.
  • the two lateral branches of the dancer crosspiece are connected by two vertical dampers to the chassis, by the fact that the lower middle part of the dancer cross member is connected by at least one damper transverse to the chassis and by the fact that it comprises two stops arranged between the chassis and the dancer cross member and intended to limit the lateral play of the latter.
  • the bogie comprises two longitudinal connecting rods connecting the lower lateral parts of the chassis to the dancer cross member.
  • each axle comprises two portions extending each lateral branch towards the front and towards the rear of the bogie and serving as support for eight primary suspension members cooperating with longitudinal lateral branches of the chassis.
  • the chassis is thus suspended in a precise and solid manner on the two axles, which allows a reliable and simple bogie construction.
  • the bogie may advantageously comprise on each side of the chassis at least one motor connected by at least one reduction device to the wheels, the motors and the reduction devices being arranged laterally to the chassis and the reduction devices being connected by cardanic transmission members to the wheels, the motors having drive shafts oriented transversely to the planes of the wheels and driving pinions of the reducer whose planes are parallel to the planes of the wheels.
  • This variant is particularly suitable for extreme training conditions.
  • the bogie comprises on each side of the chassis a central motor connected to the two wheels by a reduction device with two outputs, the motor and the reduction device forming a compact unit suspended from the chassis.
  • the rotating elements of a braking device are integral with one of the rotating elements of the reduction device or of the motor, while the stationary element of the braking device is fixed to the chassis or to the reduction device.
  • the invention obviously also relates to a rail vehicle comprising at least one steerable bogie such as defined above.
  • Figures 1A and 1B are schematic views of a first embodiment in exploded perspective, respectively assembled.
  • Figures 2,3 and 4 are plan, front and side views of this first embodiment.
  • FIG. 5 illustrates a detail in section of the first embodiment.
  • Figures 6A and 6B are schematic views of a second embodiment in exploded perspective, respectively assembled.
  • Figures 7,8 and 9 are plan, front and side views of the second embodiment.
  • Figure 10 illustrates some of the details in Figure 7.
  • FIG. 11 represents a rail vehicle with an integral low floor fitted with bogies according to the invention.
  • the first embodiment of an orientable bogie 10 for metric track comprises a chassis 12, two non-rotating axles 14 each carrying two wheels 16 and a cross beam 18 intended to be connected to the vehicle body on rail.
  • the non-rotating axles 14 are U-shaped with a lower central part 20 and two rising lateral branches 21 on which are rotatably mounted the wheels 16.
  • Each lateral branch 21 comprises a portion 22, in the form of a plate, intended to carry a primary suspension member 23 by means of which the chassis 12 is suspended on the two axles 14.
  • the latter have a mechanically welded or cast structure, the parts forming the hubs being forged.
  • the wheels 16 are for example of the elastic type with a new diameter of 560mm.
  • the chassis 12 with a mechanically welded steel structure also has a lower middle part 26 constituted by two crosspieces 27 having the general U-shape. These two crosspieces 27 are separated by a central space 28 in which the dancer crosspiece 18 is arranged.
  • two crosspieces 27 comprise on each side rising lateral branches 34 made integral with one another on each side by a side member or a central lateral block 30. The latter is integral with two branches 31,32 rising obliquely forward and towards the rear and having a plate 33 intended to cooperate with the primary suspension members 23.
  • the dancer cross member 18 with a mechanically welded steel structure also has a general U shape with a low central part 36 connected to two lateral branches 37 each comprising a portion 38 intended to cooperate with secondary suspension members 40 arranged between the central blocks side 30 of the chassis 12 and the dancer cross member 18 which is thus suspended on the chassis 12. It is noted that the dancer cross member 18 integrates almost entirely into the central space 28 of the chassis 12 between the two cross members 27.
  • the bogie 13 has an empty central volume in which the middle part of the vehicle body can be housed to obtain a steerable bogie for vehicles with an integral low floor.
  • the bogie 10 illustrated in FIGS. 1 to 4 is particularly intended for metric track vehicles, for example trams, but it could be adapted to all other applications.
  • the engine groups are composed of a motor 42 and a reduction gear 43 per wheel fixed to the chassis 12 of the bogie, therefore suspended thanks to the primary suspension 23.
  • a cardanic transmission member 44 connects the reduction gear 43 to the wheel 16.
  • each motor 42 has a drive shaft 52 (FIG. 2) arranged transversely to the plane of the wheels 16. This shaft 52 rotates the pinions 53 of the reduction gear 43.
  • the cardanic transmission member 44 is advantageously made up by two elastic couplings connected to each other by a hollow shaft, one placed at the outlet of the reducer and the other fixed to the wheel making it possible to create a cardanic connection between the reducer and the wheel.
  • Each axle 22 is provided with two disc brakes 46 with spring brake cylinders 47 or accumulator calipers mounted on the chassis 12 and with brake discs 48 fixed directly to the wheels 16. It is understood that the brake discs could be integral with a rotating element of the reduction gear 43 or of the motor 42.
  • the bogie further comprises, arranged on each side between the wheels 16, an emergency braking group 49 with a electromagnetic shoe 50 capable of cooperating with the rail 51 (fig. 4).
  • Connecting elements 55 are arranged between each axle 14 and the chassis. These elements include the four primary suspension members 23, four oblique connecting rods 56 (fig. 2) occupying a low position in the bogie and four longitudinal connecting rods 57 connecting the upper parts of the lateral branches 21 of each axle 12 to the upper part of the chassis .
  • the connecting elements 60 between the chassis and the dancer cross member 18 are constituted by the two secondary suspension members 40, two connecting rods for lower longitudinal forces 61 (fig. 2 and 4), two lateral vertical dampers 62 arranged between the two lateral branches 37 of the dancer crosspiece 18 and the frame 12, two substantially horizontal central shock absorbers 63 (fig. 2) occupying a low position of the dancer crosspiece 18, and two stops 64 arranged on the frame 12 opposite the dancer crosspiece 18 and limiting the lateral movements between the dancer crosspiece 18 and the chassis 12.
  • the secondary suspension members 40 are composed of double internal and external springs with elastic bases. They allow the vertical and horizontal movement of the body.
  • the "flexico ⁇ l" effect of the springs associated with an appropriate design of the elastic bases makes it possible to optimize the stiffness of the lateral suspension and thus to offer good comfort.
  • These box springs reduce the transmission of rolling noise to the body. Together with the vertical and horizontal shock absorbers 62,63, they provide excellent comfort.
  • the two lower longitudinal connecting rods 61 are arranged between the lower lateral parts of the chassis 12 and the dancer cross member 18 and make it possible to transmit the traction and braking forces without raising the bogie 10.
  • a crown of balls 66 is fixed on the lower middle part of the dancer cross member 18 and provides the connection between the bogie and the vehicle body while allowing the rotation of the bogie relative to the body and the transmission of longitudinal forces.
  • FIG. 5 shows in particular a section through a primary suspension member 23 comprising a conical male part 68 and a female part 69 fitting one inside the other between which two elastic conical annular parts 70 are arranged.
  • a suspension with integrated guidance ensuring a particularly precise connection between the axle 14 and the chassis 12, both in curves and in alignment.
  • Vertical flexibility was chosen so as to adapt to localized track faults, particularly in the sockets important left.
  • This suspension of the bogie allows the equalization of the vertical loads of the vehicle in all circumstances. Its characteristics make it possible to guarantee a good grip of the bogie and to ensure safety at derailment. It is understood that it is also possible to use a primary suspension member of any other construction.
  • the bogie 10 described above can also be provided without motorization or for any spacing, metric or normal, as well as for box widths ranging from 2200 to 2650 mm.
  • a maximum angle of rotation of the bogie is advantageously fixed at 15 ° so as not to encroach too much inside the body.
  • This concept applied to the tram, keeps a bogie wheelbase of 1000 mm while having new wheels of 560 mm in diameter. This will limit the effects of jamming in small radius curves and reduce the angle of attack between wheel and rail.
  • FIGS. 6 to 9 illustrate a second embodiment of an orientable bogie 110 for normal track, with a chassis 112, two non-rotating axles 114 each carrying two wheels 116 and a cross beam 118.
  • the non-rotating axles 114 are U-shaped with a lower middle part 120, and two rising lateral branches 121 on which the wheels 116 are mounted.
  • Each lateral branch 121 has a projecting portion forward and backward forming a plate 122 intended to carry a primary suspension member 123 which is favorably of the integrated guide type, as shown in FIG. 5.
  • the chassis 112 is therefore suspended on the two axles 114 thanks to eight primary suspension members 123.
  • the frame 112 also has a lower middle portion 126 formed by two cross members 127 having the general U-shape. These two cross members 127 are separated by a central space 128 in which the dancer cross member 118 is arranged.
  • the two cross members 127 have on each side rising side branches 134 made integral with one another by a spar or a central block lateral 130.
  • Horizontal branches 131 extend the chassis 112 on each side towards the front and the rear and are arranged opposite the plates 122 to cooperate with the primary suspension members 123. This thus provides perfect seating of the chassis 112 on the two axles 114.
  • the central blocks 130, the lateral branches 131 may advantageously be constituted by lateral longitudinal members assembled to the crosspieces 127.
  • the dancer cross member 118 also has a general U shape with a lower middle portion 136 carrying the crown 166 and connected to two lateral branches 137 each comprising a portion 138 intended to cooperate with the secondary suspension members 140 of the double spring type arranged on the lateral central blocks 130.
  • the dancer cross member 118 is thus disposed in the central space 128.
  • the structure of the bogie 110 is therefore empty over the entire median length in which the body of the vehicle can be accommodated in order to obtain an integral low floor of the vehicle .
  • the bogie 110 has a motor 142 on each side fixed to the chassis 112 and connected to the wheels by reducers 143 and transmission shafts 144.
  • the calipers 147 of the disc brakes 146 are mounted on the chassis. While the discs 148 are integral in rotation with the last pinion of the reducers 143. An exact alignment is thus obtained between calipers and brakes, therefore increased braking efficiency.
  • An emergency braking group 149 with an electromagnetic shoe 150 is mounted on the chassis on each side between the wheels 116.
  • Connecting elements 155 arranged between each axle 114 and the chassis 112 include the eight primary suspension members 123, and four stops 157 arranged between the axles 114 and the chassis 112 and intended to avoid axle-chassis separation. Due to the use of eight suspension members with integrated guide, the mounting of one or two series of connecting rods is no longer necessary.
  • the connecting elements 160 between the frame 112 and the dancer cross member 118 are constituted by the two secondary suspension members 140 with double spring, two low longitudinal force transmission rods 161 (fig. 7 and 9), two lateral vertical shock absorbers 162, a substantially horizontal central damper 163 and two stops 164 limiting the lateral movements of the dancer cross member 118 relative to the chassis 112.
  • the connecting elements 160 are therefore substantially identical to those of the first embodiment.
  • the crown 166 fixed on the lower middle part 136 of the dancer cross member 118 allows the connection and the rotation between bogie and body.
  • the traction-braking assembly illustrated in FIG. 10 can be used for any track, metric or normal, and forms on each side of the bogie a compact unit suspended from the chassis of the bogie by elastic elements.
  • the motor 142 has a drive shaft 152 oriented transversely to the plane of the wheels 116. It drives and brakes the two wheels on the same side of the bogie and is placed in the center of the reduction gear 143 which has two outputs and the two gear trains 153 of which have pinions parallel to the planes of the wheels 162.
  • Two transmission members 144 each comprising two elastic couplings connected together by a hollow shaft, one placed at the outlet of the reducer 143, the other fixed to the wheel 116, make it possible to create a cardanic connection between the reducer and the wheel.
  • Each reducer 143 is equipped with a disc brake unit 146 which makes it possible to mechanically brake the two wheels on the same side of the bogie.
  • the brake is a spring energy storage system and is controlled by a hydraulic unit, with several stages, common for the two braking units of a bogie.
  • a mechanical brake keeps the vehicle fully loaded on the maximum slope and provides the parking brake.
  • the bogie is equipped with two electromagnetic pads on the rail.
  • the bogie is therefore equipped with two motors 142 placed transversely on the right side and the left side of the bogie.
  • Each motor drives two wheels on the same side of the bogie by means of a reduction gear 143 and two cardanic transmissions 144.
  • the bogie has a two-stage suspension structure and retains the essential principles of decoupling of movements between body and bogie.
  • the bogie's rotational and yaw movements are decoupled from the body's yaw, roll and swing movements.
  • the transmission of the longitudinal bogie body forces is carried out at the lowest level permitted by the lower gauge.
  • the bogie's nose-up is minimized, thereby ensuring good grip of the tram.
  • Wheels and bent axles are the only unsprung masses; this makes it possible to limit to a large extent the vibrations transmitted to the ground.
  • a stiff front yaw damper will be installed. It will avoid raising the critical speed of the bogie in alignment and limit its yaw movements.
  • the rail vehicle 70 shown in Figure 11 is equipped with bogies 10 and represents a possibility of application to a tram.
  • the latter includes three boxes 71,72,73 and four bogies.
  • Two back-to-back seats can be placed on the podiums above the wheels.
  • the swiveling motor bogies have a reduced minimum wheelbase up to 1 m and allow an integral low floor of 350 mm with a corridor with a minimum width of 480 mm.
  • each wheel can be driven by an independent motor and gearbox.
  • the bogie has very few unsprung masses and optimal comfort thanks to the two types of primary and secondary suspension adapted to each other.
  • the wheelbase of the axles can be increased.
  • the embodiments described above are in no way limiting and that they can receive any desirable modifications within the framework as defined by claim 1.
  • the primary suspension members and secondary may be of any other kind and of another number.
  • Certain simplified bogies may be free of motorization, even of braking system.
  • the engine, the braking devices and the connecting elements may be of another type.
  • the bogie can be adapted to all types of rail vehicle and to all track dimensions.
  • the bogies with metric gauge, respectively with normal gauge, could also include two, respectively four groups of motorization.
