"Vagen convoy for trams and overground light rail vehicles"

DESCRIPTION; ,

The present "Nenenui" relates to a wagon convoy for trams and overground light rail vehicles with several coaches that work together.

The tramcar trend is well known as urban and extra-urban means of transport to make it current for stretches of limited extent.

There are therefore in the phase of development articulated kpnvois with several cars, to their basic Requirements to be expected are the standardization of the components of the convoy, the ease of transforming the convoy from an urban convoy with only two cars to an extra-urban convoy with three or more cars, the easy boarding and alighting also for passengers with special problems, such as children, elderly people, disabled people, Greatest capacity, limited power consumption, better distribution of weights and mechanical loads, simplicity and lightness of the Construction.

The aim of the present innovation is to create a convoy with several wagons of the type mentioned above, which is particularly advantageous with regard to a possible use both in use on routes in the interior a large city as well as in extra-urban use to connect with neighboring locations.

According to the innovation, one of several articulately connected and carriages or bogies running on the track by means of wheeled vehicles Convoy for trams and Upper Nordic light rail vehicles provided, which is characterized in that

the said chassis or bogies from two at the ends f.

t of the convoy accommodated undercarriages with wheels smaller diameter and one at each connection point housed between neighboring trays

Motor chassis with wheels of larger diameter exist whereby the convoy grouped the drive and operating equipment on said motor chassis around the largest possible Lowering of the flat floor of the wagons to the roadway ζ enable.

The main advance of the new abnormal convoy is undoubtedly given by the fact that the traveling chassis are arranged at the ends of the convoy and the motor vehicle pestell or the motor chassis at the connection points between the different cars. Namely, this allows the Change the number of motor chassis, and thus change the required power depending on the number the wagon, which ensures the required high performance in the case of a convoy with three or more wagons and at the same time an advantageous reduction in performance is made possible in the case of a convoy with only two cars.

Furthermore, the grouping of the equipment previously housed under the flat floor of the car allows above the Motor chassis respectively. the motor chassis, in connection with the use of running chassis with smaller wheels Diameter to lower the flat floor of the car sharply in such a way that it is easy for those passengers to get on and off. more convenient ^ f-makes who usually face difficulties such as children, the elderly and the disabled.

Said grouping also allows a better distribution of weights and stresses, both of which

be concentrated on the motor chassis in such a way that the adhesion weight (friction weight) is increased and consequently the framework of the wagons is relieved. The flat bottoms and side walls of the latter in particular can be made lighter entirely to the benefit of the simplicity and cost of the car.

An example of a convoy3 according to the innovation is for better explanation shown on the attached drawings, on which:

FIG. 1 shows schematically in elevation a convoy with two cars intended in particular for urban use;

Figure 2 shows the interior of the same convoy viewed schematically in plan;

Figure 3 the same convoy schematically in cross section shown shows;

FIG. 4 shows schematically in elevation how the convoy with two cars of FIG. 1 can easily be converted into a convoy with three Vagen transformed especially for use for out-of-town traffic can be·

The convoy with two "carriages" shown in FIGS. 1 to 3 consists of two articulated ones similar weapons 1, which are driven by a motor vehicle 3 be enabled to walk on lane 2; this motor chassis is located at the junction between the two cars; Furthermore, there are two chassis 4 at the ends of the convoy and contribute to it to enable the Vafsn.-zi '"" to run on the roadway.

_Y ¥ IE shown in Figure 1, the driving chassis 3 is provided with wheels 5, whose diameter is larger than that of the wheels 6 of the "two running chassis 4. How instead shown in Figure 2, on the driving chassis 3 in boxes 7 all drive and The convoy's operating devices are grouped, which are fed by the overhead line | 8 via a pantograph system (scissor pick-up) Q (Figures 1 and 3) 10 of the weapons to the extreme lowering and so, as shown in Fipair 3, to make boarding and alighting more comfortable for the disabled with wheelchairs, for children, for the elderly and so on.

As shown in FIG. 1, the convoy has two single-leaf doors 11 at the ends and four double-leaf doors 12 in double position. The former are intended for the sole purpose of disembarking passengers, while the latter are intended for boarding and disembarking. In combination with the arrangement of the seats (single seats 13 and double seats 1 * 0, as shown in Figure 2, the doors determined this arrangement to cause the strongest siting of the passengers near the drive chassis 3, which with consequent better distribution Weights and stresses.

The convoy shown in Figures 1 to 3 with two trolleys has proven to be particularly advantageous in the City traffic, where the only motor vehicle seatell with the it is provided, a power consumption restriction

enables. He can, however, quickly get the job done in suburban traffic can be adjusted by .an intermediate car 15 with double-leaf doors 12 added is and two motor chassis 3 are provided, each with equipment arranged thereon, in the Areas of articulation with the two TJndwagen 1 (Figure 4).

As shown in FIG. 2, the two wagons 1 of the convoy of FIGS. 1 to 3 are connected to the motor vehicle 3 via pairs of pins 16; the same applies, although not shown, to wagons 1 and 15 of the convoy of FIG . In both types of convoy, the two pins 16 are preferably somewhat off-axis with respect to the axis of the convoy on the side not provided with doors, i.e. on the side that is closer to the other of the two tracks usually provided for tram and light rail traffic. The purpose of this is to reduce the maximum amount of space required inside the curve while the wagons are always the same width.
