The floor 29 extends at substantially the same height as the rolling plane of the rake throughout the interior space 18 and the passage 16.

Referring to FIG. 2, each car body 4 has a leading floor 32 and trailing floor 34 positioned at a relatively high height with respect to the rolling plane of the rake, and a relatively low height with respect to the rolling plane of the rake. It has a stepped floor 30 having a central floor 35 located.

The leading bottom 32, trailing bottom 34, and center bottom 35 are located below the leading portion 24, trailing portion 28, and central portion 26 of the interior space 18, respectively. do.

Referring to FIG. 3, bogie 6 includes frame 360, two axles 38 mounted on frame 36, four wheels 40 mounted in pairs on axle 38, and body 4. It includes two shock absorbers (42) interposed between the leading bottom (32) and the frame (36).

More specifically referring to FIG. 4, the frame 36 connects two longitudinal base bars 44 parallel to each other, and two longitudinal base bars 44 and two transverse cross bars parallel to each other ( 46). The axle 38 is mounted to two longitudinal ends of the two base bars 44. The cross bars 46 are arranged symmetrically about the middle transverse vertical plane of the two axles 38, each extending between this plane and one of the axles 38. Bogie 6 also includes a brake disc 48 mounted to the axle 38 and cooperating with a brake actuator 50 mounted to the cross bar 46.

The pivot joint means 8 is arranged below the leading floor 32, the leading bottom 32 of the body 4 pivots on the view 6 about the pivot axis A which is perpendicular to the rolling plane of the rake. Possibly mounted. The pivot joint means 8 is arranged in the middle transverse vertical plane of the two axles 38 and in the middle longitudinal vertical plane of the two cross bars 46. These means are of known type and will not be described in detail.

The ball joint means 10 comprises a leading arm 52 extending from the leading bottom 32 below the connecting passage 16 and a stirrup 54 integral with the leading arm 52.

3 and 4, the leading arm 52 includes a first portion extending downwardly and forwardly from the leading bottom 32, and a second portion horizontally extending forwardly. Stirrup 54 extends from a second portion of leading arm 52 and includes two parallel vent arms 56, each vent arm 56 transversely right from leading arm 52. A first portion extending into the first portion, and a second portion 60 in which the first portion 58 extends vertically.

The corresponding ball joint means 12 comprise a trailing arm 62 extending substantially longitudinally rearwardly from the trailing bottom 34. This trailing arm 62 is located directly above the first portion 58 of the vent arm 56. The corresponding ball joint means 12 also comprise a central plate 64 extending transversely right from the trailing arm 62. The center plate 64 is coupled between the second portions 60 of the stirrup 54. The space G remains between the plate 64 and the second portion 60 of the vent arm 56 on both sides of the plate 64, as shown in FIG. 5.

In the second portion 60 and the plate 64, cylindrical bores 66, 68 having coaxial and longitudinal axes are drilled, respectively.

Referring to FIG. 5, the bore 68 accommodates a ball 70, with a sleeve 72 of elastic material interposed between the ball 70 and the inner side of the bore 68. The ball 70 is generally made of rubber.

The ball joint means 10 also comprises a shaft 74 extending through the bore 66 of the two vent arms 56 and passing through the ball 70 provided with an orifice.

The ball 70 is firmly fixed so as not to move along the shaft 74 by any suitable means. The elastic sleeve 72 is integral with both the ball 70 and the plate 64.

Thus, it should be understood that angular displacement is possible between the trailing arm 62 and the stirrup 54 around the ball 70.

A portion of the bogie 6 located on the trailing side of the pivot axis A is arranged below the leading bottom 32 of the vehicle body 4. A portion of the view 6 extending forward of the pivot axis A first extends below the leading floor 32 and then below the passage 16 and finally the trailing floor 34 of the preceding vehicle 2. ) Is partially extended down. The foremost axle 38 extends in the region of the trailing end of the preceding vehicle 2.

4 shows a ball joint 14 positioned longitudinally below the passage 16. The ball joint 14 is also located between the two axles 38 of the bogie, specifically between the leading axle 38 of the bogie and the pivot axis A, more specifically, the leading cross bar 46. And between the leading axle 38.

The ball joint 14 is interposed vertically between the bogie 6 and the bottom of the connecting passage 16, more specifically between the leading axle 38 and the bottom of the connecting passage 16.

The ball joint 14 is arranged at a height lower than or equal to the pivot joint means 8 with respect to the rolling plane of the rake.

The ball 70 of the ball joint 14 is arranged at a distance of less than 2 m in the longitudinal direction from the axis A of the pivot joint means 8, preferably at a distance of 1 m from the pivot joint means 8.

The rake may comprise a vehicle having a pantograph arm 76 mounted to the roof of the vehicle body 4, the pantograph arm 76 being in a straight line with the axis A of the pivot joint means 8 of the roof. It is preferably arranged at the leading end.

The aforementioned train rake has several advantages.

The ball joint 14, which bends one vehicle 2 with the preceding vehicle, is offset forward with respect to the pivot joint means 8 of the vehicle 2 on the bogie 6. In addition, the ball joint 14 is arranged at a height lower than or equal to the pivot joint means 8. Therefore, it is possible to arrange the bottom of the passage 16 at the same height as the bottom of the interior space 18 of the vehicle 2.

In the prior art, as shown in FIG. 1, since the ball joint was disposed above the pivot joint means and below the passage, the bottom of the passage 16 was placed higher than the bottom of the central portion of the interior space 18 of the vehicle.

The ball joint 14 and pivot joint means 8 according to the new configuration of the present invention allow the bottom height of the passage 16 to be about 125 mm lower than in the prior art.

Thus, it is possible to have a floor of the same height across all vehicles of the rake so that passengers traveling from one vehicle to the other do not face a difference in height.

It should be understood that by separating the ball joint from the pivot joint, the overall lateral space occupied when the vehicle is bent is reduced. In the transverse width of the vehicle, the transverse protrusion distance to the rail is shortened when the vehicle is bent and run.

According to another aspect, it is possible to increase the transverse width of the vehicle body in the overall maximum transverse size when curved. For a 1 m displacement between the ball joint and the pivot joint means, a vehicle body width increase of 35 mm is possible.

Moreover, since the pivot joint means 8 is arrange | positioned under the leading part of the vehicle body 4, it is possible to install the pantograph arm 76 perpendicularly to the pivot joint means 8 in a straight line. This arrangement allows the pantograph arm to simply displace relative to the cutlery 78.

If the pivot joint means 8 is arranged below the leading portion of the vehicle body but not below the passage 16, the shock absorber 42 can be placed directly on the leading bottom 32 of the vehicle body 4.

The above-described train rake may have several variations within the scope of the present invention.

Thus, by alternatively lowering the bottom of the passageway and the bottom of the interior space of the vehicle body, a height difference is formed between these floors. For this reason, the height at the time of riding in the inside of a vehicle body from a platform may be low.

In a variant, the ball joint 14 between the vehicle and the preceding vehicle is arranged below the trailing floor 34 of the preceding vehicle, not below the floor of the passageway, so that the two vehicles are in communication.

The bogie 6 of the vehicle 2 may be connected to the trailing floor 34 of the vehicle body, rather than to the leading floor 32 of the vehicle body 4. In this case, the leading end of the vehicle 2 is supported by the trailing end of the preceding vehicle via the ball joint 14.

The invention also provides for each vehicle 2 two bogies 6, one bogie 6 lying under the leading floor 32 of the body 4 and the other bogie 6. Relates to an articulated train rake, which lies beneath the trailing bottom 34 of the body 4. In this case, the ball joint 14 only serves to bend one end of the vehicle 2 with the end of the preceding vehicle, and does not support the end of one vehicle.

The above-described train rake may be provided with electric power or heat power.

A vehicle having a ball joint 14 positioned below the pivot joint 8 may be a powered vehicle or a non-powered vehicle. The powered vehicle may be arranged at the end of the rake or at an intermediate position between the two non-powered vehicles.

According to the present invention, there is provided an articulated train rake, which allows for easier passage between vehicles compared to the prior art.
