Definitions

• the invention relates to a bogie for railway use. It also relates to the wagon provided with said bogie.
• the chassis of a bogie for example, of the Y33 type, the axle load of which has been limited to eighteen tonnes per axle, consists of a carrying cross member on which the pivot articulation of the wagon body rests and this carrier beam is, by its two ends, fixed on side members. These beams are associated with the four wheels of the bogie by a suspension.
• suspensions are each formed by two groups of coaxial springs said to be, for the first spring, tare and, for the second spring, load. Each of its suspensions is supported substantially under the end of a beam.
• Each spar includes: - an upper sole
• the core is in the form of a veil to form I-shaped beams.
• the upper sole locally forms two bumps to obtain constant inertia and, on the other hand, at the fold of this sole to form the bump, are fixed on the side and on the other side of the core, reinforcing gussets preventing crushing.
• the invention therefore proposes to solve at least the problem mentioned above.
• the subject of the invention is a bogie of the aforementioned type comprising:
• a lower sole which, from each of its two ends, gradually deviates from the upper sole to give the assembly a generally trapezoid shape with the small base located at the bottom -
• the invention also relates to the wagon provided with said bogie.
• each of these bogies includes:
• a lower sole 6 which, from each of its two ends and at a predetermined distance from these ends, gradually departs from the upper sole 5 to give the assembly a generally trapezoid shape with the small base located at the bottom,
• This core 7 is a simple veil, so that the side members have an I-shaped section at the ends.
• the crosspiece widens at its ends and connects to the web or core 7. It also defines a trapezoid with the small base as close to the ground. Over a large part of its length, the crosspiece is of constant width.
• This bogie accepts a load of twenty tonnes per axle. According to a feature of this bogie:
• the upper sole 5 is located in a horizontal plane and - on the other hand, the width L of this sole 5 increases rapidly from its two ends 5A, 5B so that the internal edge 8 of this sole 5 is located at a predetermined distance D from the vertical plane P passing through the external flanks of the wheels 18 of the bogie to just preserve the play necessary for the lateral movement of the wheels.
• the lower sole from its end to its median transverse plane has a first zone Z1 parallel to the upper sole 5 then a second zone Z2 inclined downwards then, finally, a third zone Z3 also parallel to the upper sole.
• zone Z1 the thickness of the spar is constant except for the end part.
• only the external face 7A of the core 7 of the spar has a gusset 10 which extends between the lower face of the upper sole and the upper face of the lower sole.
• the gusset is located in zone Z1 slightly before the transition with zone Z2.
• the reduction of the width of the upper sole is done from the axle.
• This part is asymmetrical, the internal edge being more inclined than the external edge.
• the upper face of the upper sole of each spar carries a reading blade 11, one end 11A of which is fixed, for example, by four points on this upper sole.
• the thickness of the core of the anterior spar was previously fourteen millimeters and the width of two hundred millimeters.
• the bogie thus modified can support at least twenty tonnes per axle.
• the wagon is of the type with two assembled platforms, each platform being carried by two bogies of the aforementioned type or of the one platform type, the platform being carried by two bogies of the aforementioned type.
• this platform comprises in the middle part two external beams 12 which connect two floors 13 constituting the ends of each platform.
• the floors are limited to the area above the bogies.
• the longitudinal members 12 of these platforms are locally maintained at the spacing required by cross members 14.
• the ends of the wagons have conventional means of connection with another assembly and therefore comprise two buffers and a coupling hook.
• the bogie instead of using a sled rod which bypasses the underside of the carrier cross member, the bogie comprises a tubular connector rod 15 for the brake linkage which locally crosses the carrier cross member. This limits the weight of the bogie and therefore increases the load.
• Another modification is made compared to the bogie type Y33 defined at eighteen tonnes per axle in the UIC standard to which reference is made and the content of which is included in the request.
• the table 16 for supporting the springs is lowered by about fourteen millimeters.
• the suspension assembly has been modified to incorporate the organs, elements and functional clearances of a twenty-ton suspension while respecting the dimensions of the envelope of a standard Y33 bogie.
