Description

AUTOMOTRICE FOR THE TRANSPORT OF TRAVELERS

The present invention relates to a self-propelled travelers, and more particularly a modular self-propelled passenger capacity and maximum speed term.

Previous art Train or motor rail architectures are differentiated according to that they are motorized concentrated or distributed, depending on the cars the components are connected in an articulated or non-articulated manner, according to available and the number of motor and carrying bogies and, depending on their has one or two levels.

For the sake of clarity, these different concepts are defined in the following paragraphs.

Train or self-propelled A self-propelled car has at least one motorized car, that is, say comprising at least one traveler compartment and at least one traction chain. A self-propelled vehicle may therefore contain only motorized cars or include non-motorized cars and at least a motorized car.
A train is composed of one or more engines and a certain number of passenger cars. A motor is not accessible to passengers and includes among others a chain of traction.

Concentrated or distributed motorization The chain of traction includes several equipernents, which are either electrical components are electronic components of power and control, adapted to capture electrical energy from a source of traction (for example a catenary line), transform it and Ia converting into electric power signals of electric motors motor bogies to ensure that the train or the motor vehicle is in good condition.

2 The motorization is said to be concentrated when all the components of traction chains are grouped in a single location, for example in the motor of a train. The motorisation is said distributed when the components of the drivetrain are spread over several cars, under the chassis of cars or on the roof.

Articulated or non-articulated cars A bogie conventionally includes a resting bogie frame on two axles. By axle, we mean generally a pair of coaxial support wheels on the rails of a railway.
A motor bogie comprises at least one electric motor driving wheels of at least one of its axles, called axle engine. In contrast, a non-motorized bogie is called a carrier bogie.

Two adjacent cars are said to be articulated (or in articulee) when a first car is supported by one of these extremities on a bogie and that *, extremite you vis-à-vis the second car based on the end of the first. The bogie is therefore on horseback under extremities of the two adjacent cars. A self-propelled car two articulated cars therefore have three bogies, since the ends free of both cars are each based on a bogie.
In contrast, two adjacent non-articulated cars are not, a each of their ends, supported on a common truck, each car based on two bogies. A self-propelled car composed of two non articules therefore has four bogies.

Car has one or two levels A car is said to have a level when it has a compartment of travelers on one floor level, and it is said to have two levels where there are two passengers on two levels, superimposed one above the other.

3 There are one-level, non-articulated and powered trains concentrated in one or two motor. Because of the non-articulation, this architecture presents the inconvenience of having a large number of bogies this which increases the resistance to progress and therefore Ia energy consumption of the motor vehicle. A large number of bogies also requires many maintenance operations.

There are also high speed self-propelled articulated and motorized distributed, with different distributions of traction equipment in cars, different locations of motor bogies or drive axles according to the architectures. These motor coaches consist of several motorized cars, each resting on two bogies.
This type of motorization requires a large mass of power needed to connect the energy sensing device (s) to the engines through each traction equipment, cables that therefore run between all cars equipped with either a capture of either traction chain equipment or a bogie engine.
There are also one-level or two-level trains mixed and motorized concentrate. Passenger cars rest on bogies carrying and are framed by two motor, at each extremity of the train, resting on motor bogies. The links of this train are called mixed because different types of connections connect cars and the drive. The cars are connected to each other by an articulated link, and the cars are connected to the motor by a non articulated connection.
This architecture presents a capacity in number of passengers reduced compared to a self-propelled vehicle of the same length, since motorists are not accessible to passengers.

4 The performance of these vehicles is related to their architectures:
is possible to run a high speed train at speeds least, but to the detriment of passenger capacity since the mass of traction is not liberable. It is not possible to circulate a vehicle has a speed greater than its maximum speed since no traction chain or no motor can be added simply. The manufacturers must therefore design a vehicle specific to each range speed / passenger capacity.

It is therefore an object of the invention to propose a self-propelled do not have the drawbacks of state-of-the-art architectures.

For this purpose, the invention proposes a self-propelled passengers including two pilot cars and intermediate cars, carrying bogies, motor bogies having at least one axle motor and is characterized in that the cars are all articulated between two by two, the motor has three or four chains of action, a chain of traction is available in each pilot car and at least a chain of traction being arranged in a single intermediate car, a motor bogie is provided under at least one of the two ends of said pilot cars, a motor bogie is provided under at least one both ends of said intermediate car comprising at least one traction chain.

The self-propelled vehicle includes one or more of the characteristics following, taken in any technically feasible combination:
- each traction chain drives at least one driving axle of or motor bogies arranged under one or both ends of each car in which the said traction chain is located;

- the motor includes, between the intermediate car comprising the minus one pull chain and each of the pilot cars, at least one intermediate car without traction chain;
- at least one intermediate car without traction chain

5 is supported at at least one of its two ends by a carrier bogie;
- the cars are on two levels.
Description of the invention The self-propelled vehicle is entirely articulated, that is to say that the cars are all articulated between them two by two. A bogie is on horseback under two adjacent ends of two adjacent cars, the free ends of pilot cars based on a single bogie.

EIIe has three or four chains of traction, a chain of traction in each pilot car and at least one chain of traction (one or two) being arranged in a single intermediate car.
For this reason, this intermediate car will be named car motorized intermediate. The self-propelled is therefore a concentrated motorization, Ia concentration in three cars, whether there are three or four traction chains.

A motor bogie is provided under at least one of the two ends the two pilot cars and the motorized intermediate car comprising a chain of traction. In other words, every car with a traction chain is supported at both ends by a bogie motor and a bogie carrier, either by two motor bogies.

The self-propelled car includes, between the motorized intermediate car and each of the carriages, in the same way as an intermediate car, seen

6 traction chain. As this intermediate car does not have of chain of traction, it is called trailer.

A trailer is supported on at least one of its two ends by a carrier bogie. A trailer is therefore supported at these ends either by a bogie carrier and a motor bogie, or by two carrying bogies.

A self-propelled vehicle according to the invention therefore complies with a rule alternation of cars with a chain of traction and not including, and an alternating rule of motor bogies and bogies in order to respect the maximum load on the axle.

Indeed, all railway vehicles must respect the constraint the axle load, the value of which is imposed by the infrastructure or by the standards applicable on the tracks where these vehicles circulate.

The axle load of the motor according to the invention is kept below the maximum allowable load because:
- each pilot car is supported on a dedicated truck and a bogie common with another car, and so has its charge spread over a more large number of axles as intermediate cars. Therefore, a pilot car can support a larger mass than the others cars without exceeding the maximum axle load. Each car driver thus receives travelers, the chain of traction as well as all or part of auxiliary energy production equipment (electric and pneumatic).
- trailers without traction chains have a lower curb weight than the pilot cars and the motorized car.
- The motorized intermediate car receives passengers and equipment of at least one traction chain. But the motor bogies have each end of the motorized car supports each one of them.
mass of the motorized intermediate car and half of the mass of Ia

7 trailer, since at least one trailer is interposed between Ia pilot car and the motorized intermediate car. Like a trailer is less heavy than the motorized intermediate car, each motor bogie riding on one end of the intermediate car motorized and under the end of the adjacent trailer supports a mass average remaining below the maximum axle load.

Weight balancing on each bogie carrier and bogie engine is also obtained by optimizing the distribution of the different traction or auxiliary equipment of the motor vehicle, and of the interior of cars that differs according to the desired comfort (type and number of different seats according to the class of the car).
The interior layout of the motorized intermediate car in particular depends on the mass of Ia or the traction chains, which themselves depend on the desired performance of the motor vehicle (multi-tension traction, maximum speed, etc.). For example, if the mass of installed traction equipment is high, the interior layout of the motorized intermediate car will be allege and conquers like a car-bar, a car offering services or having a reduced passenger capacity relative to the capacity of the trailers.

Each traction chain drives at least one driving axle of or motor bogies placed under one or both ends of the cars in which are arranged one or more chains of traction.
The self-propelled vehicle can therefore comprise three to twelve driving axles, depending on whether each pilot car and the motorized intermediate car are supported by one or two motor bogies, which themselves include one or two drive axles.

One advantage of a fully articulated architecture is that The motor is more stable in case of deraillement. Because of the architecture

8 articulated, resistance to progress and thus energy consumption needed to train the vehicle remains limited compared to a non-articulated self-propelled car of the same length, since there are fewer bogies.
Maintenance operations are also reduced. Because of the self-propelled vehicle, the vehicle offers a high capacity since the length of the vehicle is used to receive passengers.

An advantage of the concentration of traction chains in pilot cars and in a single motorized intermediate car allows for better protect and control fires by physically separating chains of traction from each other, and by physically separating the traction chains of passenger compartments.

The invention and other advantages will be better understood when reading The description that follows, given solely as an example, and made in referring to the accompanying drawings, in which - Figures 1, 3 and 4 are schematic side views self-propelled according to the invention according to several embodiments, FIG. 2 is a table schematically showing the position driving axles according to the number of cars I'automotrice.

By convention, the wheels of the driving axles are blackened on the FIGS.
First embodiment As shown in FIG. 1, a self-propelled vehicle A comprises seven trailers 3 and a motorized intermediate car 4 arranged between two pilot cars 2.

9 A first pilot car 2 is located at a first end of The motor vehicle A (starting from the left in FIG. 1). It presents a free end, where is located a driving cabin 9, and is based on a bogie engine 6 compounds of two driving axles 5. A first chain 8 is disposed under the passenger compartment 10 of this first pilot car 2. At its opposite end, the pilot car 2 is articulated with a first trailer 3. The two ends vis-à-vis cars 2 and 3 are based on a single engine bogie 6, consisting of two drive axles 5.
The first trailer 3 therefore shares at its first end a bogie engine 6 with the pilot car 2, and shares at its other end a bogie carrier 7 with the second trailer 3 adjacent.
The second trailer 3 is articulated to the first trailer 3 and has the third trailer 3. The second trailer 3 shares with each of Ia and the third trailer 3 a bogie carrier 7. The third Trailer 3 is articulated to a motorized intermediate car 4, located in The motor of this mode of realization in fifth position starting from Ihe left.
None of the first three trailers 3 have a chain of traction 8.

The motorized intermediate car 4 shares, at each of these extremities, a motor bogie 6 with adjacent trailers. Two strings 8 are located under the traveler compartment 10 and feed motor bogie engines - each consisting of two axles motors - located at each end of the motorized intermediate car 4.
The following four trailers are also articulated and based on carrier bogies 7, except for extremlts trailers 3 articulated with the motorized intermediate car 4 or with The pilot car 2, which are based on engine bogies 6. The second Pilot car 2 is identical to the first one.

All cars 2, 3, 4 of autotractor A have a 5 passenger compartment 10. Each of the cars 2, 3, 4 communicates with Ia or each adjacent car by a gangway 11. As the the vehicle is fully articulated, the autotractor A of Figure 1 has eleven bogies, six motorized bogies 6 and five carrying bogies 7, for a length about 200 m. In this embodiment, all the axles of the bogies

10 engines are motorized. Such an automobile can carry at least 550 passengers has a commercial speed of at least 330 km / h.

In each of the pilot cars 2 and intermediate motorized 4, Ia or the traction chains 8 are arranged under the floor of the passenger compartment 10 in order to preserve the length of the compartment traveler 10. Fig. 1 schematically represents the location of traction shafts 8 under the entire length of the passenger compartments 10 cars 2 and 4 but according to the actual size of the different components of the traction chain 8, this can be extended only partly below the floor of passenger compartments 10.

Alternatively, the traction chains 8 of the pilot cars 2 can placed in intermediate compartments between the cabin of line 9 and the passenger compartment 10.
In a conventional manner, each of the pilot cars 2 is provided with a pantograph 12 for capturing electrical energy on a catenary line (no shown).

A high voltage cabie 13 distributes electrical energy captured by each pantograph 12 6 I traction chain 8 located in the car

11 motorized intermediate 4. For reasons of clarity of the drawings, the cables 13 are shown on the outside of the cars in phantom. In practice, these cables extend for example on the roof.

The concentration of traction chains 8 and motor bogies 6 on a very limited number of cars can limit the mass of cables necessary, since only high voltage cables 13 extend between the pilot cars 2 and the traction chain 8 of the intermediate car motorized 4. These cables have a smaller mass than the mass of Power cables of the architectures of the self-propelled machines of the prior art. The The complexity of wiring is also significantly reduced.

Variants of the first embodiment Figure 2 shows in the form of a table two configurations possible of the motor according to the first embodiment given to as an example. Are only numbered the pilot cars 2, the cars motorized 4, traction chains 8, engine bogies 6, axles engines 5, carrier bogies 7, passenger capacity and speeds possible exploitation.

A self-propelled car consisting of seven cars, comprising two pilot cars 2, four trailers 3, a motorized intermediate car 4 and four motorized axles 5, requires only three traction chains 8.
A single traction chain 8 is therefore arranged in the car intermediate motorized 4, in contrast to the first embodiment.
In this variant, two motor bogies 6 support both ends of the motorized car 4, but each has only one drive axle 5. The place released by the second pull chain can be exploited to install ancillary equipment or mass equipment, it may be operated to install more seats in the 10 compartment of the car

12 motorized intermediate 4. In this same variant, only the bogies under the free ends of the pilot cars 2 are motorized, and they comprise each two two-wheel drive 5. This variant has seven cars has therefore four engine bogies 6 but six drive axles 5. This self-propelled can carry between 350 and 400 passengers (depending on interiors) and travel at least 300 km / h.

The second variant has ten cars of the motor vehicle according to the invention is identical to the seven-car variant has three additional trailers. She can present the same performance of the first embodiment of the motor vehicle A
increasing the power at the axle.

Thus, the motor vehicle according to the invention is completely flexible in terms of passenger capacity and speed since it can include seven to eleven cars, three or four traction chains 8, three to twelve drive axles 5 distributed on three to six bogies engines 6 and can reach a maximum speed between 140 and 350 km / h.

This modularity is achieved by the simplification of the types of cars (pilots 2, trailers 3 and motorized 4) while applying the rule alternating trailers and cars receiving a traction chain 8 and the alternating rule of the motor bogies 6 and the carrying bogies 7 for respect the maximum load on the axle.

Second embodiment As represented in FIGS. 1, the motor vehicle A does not comprise that cars have only one level. As a variant, the pilot cars 2 and the n two .1 '~ ....... ~ 7 ~ ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ie represent.

13 Advantageously, in a self-propelled B having cars a two levels, the lower level of a pilot car 2 and the car motorized intermediate 4 receiving a traction line 8 serves to house this or these traction chains 8, the other level being reserved for travelers.

The intercirculations 11 are placed at the high level to pass from one trailer 3 has another. On the other hand, the interconnections between the cars pilots 2 and adjacent trailers 3 are at low level. A stair (not shown) has in the pilot car 2 and in the trailers 3 allow to reach the high level from the access doors (no represented) cars 2, 3, 4.

Third embodiment For a short rail car, of the order of 120 to 160 m, it is advantageous to reduce the number of motor bogies by removing Ia intermediate motorized car 4 receiving Ia or traction chains 8, as well as to remove the associated motor bogies 6.
Thus, in the variant shown in FIG. 4, on which the references to items similar to those in Figure 1 have been canned goods, a self-propelled C differs from that of previous embodiment in that it includes only trailers 3 without traction chains 8. The self-propelled C is therefore devoid of motorized intermediate car 4 receiving a traction chain 8.
The self-propelled C comprises four motorized bogies 6, arranged under the free ends of the pilot cars 2, and on horseback under the end a pilot car 2 and the end of the trailer 3 adjaceiiie. Seior'i ie ratio

14 power / mass desired, four to eight axles can be motorized, each engine bogie 6 having at least one driving axle 5.

As a result of the abolition of the motorized intermediate car 4, the power / mass ratio of a short rail vehicle remains high enough for the motor to circulate at high speed while having a power optimized traction given its operation. This possibility adaptation of the traction power is not possible on a train, since the motor has a traction power dimensioned for the maximum number of cars to tow: if cars are removed intermediates, the power is unnecessarily over-sized. adaptation traction power is not easily achievable on a motorized self-propelled since removing a car returns to remove an element from the traction chain.
