Description

The invention relates to a stand-up passenger transport system with a lane arrangement and vehicles, the lane arrangement consisting of a vertically stressable plate-shaped lane and two eccentric, web-like or wall-like carriers running in the direction of travel, and the vehicles for supporting on the lane have at least partially drivable wheels with horizontal axes .

Passenger transport systems are gaining in importance as feeders, for example between airport facilities and railway stops or city centers. Because of the already existing buildings and infrastructure, the lane arrangement of the transport systems usually has to be raised.

In the passenger transportation system currently under construction for Frankfurt (Main) Airport, vehicles are provided with laterally arranged wheels or drive wheels, by means of which the vehicles are supported on vehicle-wide carriageway slabs with a width of the order of 2.50 m. The carriageway slabs are attached to two off-center beams that run in the direction of travel. The vehicles are steered via a guide rail arranged in the carriageway slab.

A disadvantage of the known passenger transportation system is the large cross-section, in particular in the transverse direction, of the roadway arrangement and thus the corresponding use of materials. As far as the pavement slab for If maintenance work or in an emergency is to be used as an escape route, a handrail is also required to protect people against falling.

The present invention has for its object to provide a passenger transportation system of the type mentioned, which has a narrower lane arrangement.

This object is achieved in that the plate-shaped carriageway is located at the bottom of an upwardly open U-shaped carriageway arrangement, the web-shaped or wall-shaped supports forming the legs of the U-shape of the carriageway arrangement in such a way that the running wheels are arranged so closely to one another that their common width - measured over the respective outer surface - does not exceed 2/3, preferably 9/20 (45%) of the vehicle width, and that the vehicles have upper and lower guide roller pairs which are offset at a vertical distance from one another and are intended for rolling on the inside the upward web or wall-shaped carrier are provided.

The U-shaped, trough-shaped lane arrangement, which is open at the top, represents a structurally favorable profile, the material being suitable for absorbing both vertical and transverse forces. It also has the advantage that the carriageway can be used as an escape route by people in an emergency, the wall-shaped, side beams providing fall protection.

The close arrangement of the impellers or the limitation of the width over the impellers makes it possible to dimension the trough-shaped track arrangement small.

The lateral stability is finally ensured by pairs of guide rollers arranged one above the other, which are pretensioned against the inside of the side Support the carrier walls of the carriageway arrangement. The preload has no adverse effect because it occurs symmetrically.

In order to be able to use the possibility of the escape route, it is provided according to a further development of the invention that the vehicles have doors on their front sides and descent devices leading to the carriageway. It is also possible to escape in the case of a train composed of several vehicles, since the passengers can get from one vehicle to the other through the front doors and thus ultimately get out of the train. The escape route is at the longest to the next stop, at which exit aids are to be provided, with the help of which passengers can get out of the trough onto the platforms. Leaving the vehicle or a train should always be done forward in the direction of travel so that an accident by following vehicles is excluded. In addition to the exit options at the stopping points, it is possible to provide exit hatches and escape stairs on the supports supporting the roadway arrangement.

In an advantageous development of the invention, the descent devices towards the roadway are designed as fold-out ladders, for which only a small storage space is required within the vehicle.

In order to be able to make optimum use of the interior of the trough-like roadway arrangement and also to avert danger to persons in an emergency or during maintenance work, it is further proposed to arrange the energy supply lines on the outside of one of the web-shaped or wall-shaped supports.

In an advantageous embodiment of the invention, the vehicles have a structure which is supported by air springs on a chassis and is positively connected to the latter in the longitudinal and transverse directions by means of links. By The air springs ensure a high level of driving comfort for the travelers, while the forces between the vehicle body and the chassis, which arise when accelerating, braking and cornering, are safely transmitted via the handlebars.

According to a further development of the invention, an articulated undercarriage is provided for the curve mobility of the vehicles, with each undercarriage part being assigned an upper and a lower pair of guide rollers and the entire undercarriage each having an additional upper and lower pair of guide rollers.

The passenger transportation system has an upwardly open U-shaped carriageway girder 1, which rests on supports 2 which are arranged at a distance of approximately 30 m. Stops A, B with known entrances and exits for people can have an average distance of, for example, 800 m.

The carriageway girders 1 have - seen in cross section - a plate-shaped part 3 with a carriageway 4 and on each side a wall-shaped part 5, 5 'with a guideway 6 or 6', the wall-shaped parts 5, 5 'as it were the legs of the Form the U-shape of the carriageway girder 1. The height of the guideways 6, 6 'is substantially equal to the width of the carriageway 4 and is e.g. one meter. On the outside of the wall-shaped part 5 ', lines 7 with contact protection for the electrical energy supply (busbars) and possibly for signal transmission are arranged.

The passenger transport system also has passenger transport vehicles or vehicles 10. Each vehicle 10 is supported on the roadway 4 with two axles each by two - in the transverse direction - closely arranged wheels 11. The wheels 11 equipped with pneumatic tires of at least one axle of the vehicle 10 are flanged directly to an axle drive 13 (FIG. 7). However, all of the wheels 11 can also be driven.

For guiding the carriages, horizontal guide rollers 15, 15 'are provided via links 14, 14' near the carriageway 4, which have a ring of polyurethane on their circumference.

At a distance above the lower guide rollers 15, 15 ', further guide rollers 17, 17' are in turn arranged via links 16, 16 '. The guide rollers 15 to 17 'are pretensioned against the guide tracks 6, 6'. The upper guide rollers 17, 17 'are arranged as close as possible to the upper edge of the guide track 6 or 6'. They have the task of stabilizing the vehicle in its position against lateral forces and moments (in relation to the lower guide rollers 15, 15 ') from roll movements, centrifugal forces, wind etc.

The vehicles 10 have holders 19 with current collectors 20 on the side under their vehicle body or the vehicle cabin 18, which are provided for contact with the energy supply lines 7.

The vehicle body or the vehicle cabin 18 has, in addition to the usual side entry and exit doors 21, emergency exit doors 22, 22 'on the front or front sides. In an emergency, e.g. in the event of a significant malfunction or in the event of a fire, the emergency exit door 22 or 22 'is opened and the passengers can get onto the carriageway 4 of the carriageway girder 1 via a foldable ladder 23 stowed in the vehicle cabin 18. The wall-shaped parts 5, 5 'of the trough-shaped carriageway girder 1, which are designed in the form of a "U", are used with their height indicated above as fall protection.

Fold-out railings 24 are assigned to the emergency exit doors 22 and 22 ', respectively, in the direction of the conductors 23 have extendable parts 25. An escape route through the emergency exit doors 22 and 22 'is also provided for vehicles which, as indicated in FIG. 6, are connected to one another via their coupling 26 to form a vehicle group or train.

For cornering, the vehicle 10 is provided with a two-part articulated chassis 30. The undercarriage 30 has two undercarriage parts 31a, 31b which, as a welded construction made of hollow aluminum profiles, are each connected to one another in the longitudinal center plane by an upper and a lower swivel or universal joint 32 or 33. In order to be able to compensate for the length difference that occurs when cornering in relation to the vehicle body 18, the swivel joints 32, 33 are arranged in a longitudinally elastic manner on one of the chassis parts by means of rubber spring elements 40 under prestress.

The wheels 11 are flanged to the respective axle drive 13 in the direction of the outer ends of the chassis supports 31a, 31b. The impellers 11 are driven by an electric motor 34 flanged to the axle drive 13. The chassis parts 31a, 31b are provided with clutches 26 on the end face.

The steering or guidance of the chassis parts 31a, 31b is performed by three lower pairs of guide rollers 15, 15 ', 15a, 15a' and 15b, 15b 'and - in addition - three upper pairs of guide rollers 17, 17', 17a, 17a 'and 17b, 17b' causes. The guide roller pairs 15, 15 ', 17, 17' and 15b, 15b ', 17b, 17b' are each arranged at the ends of the chassis parts 31a and 31b, the guide roller pairs 15a, 15a 'and 17a, 17a' are in the middle of the Articulated trolley 30, ie arranged in the area of the universal joints 32, 33 on the chassis part 31a.

When cornering, the undercarriage parts 31a, 31b and, at the same angle with them, the running wheels 11 are corresponding to FIG Guide of the guide rollers in particular 15a, 15a 'and 17a, 17a' deflected, so that the wheels assume a steering position adapted to the curve. The guide rollers 15 'etc. or 17' etc. mounted on the links 14 etc. or 16 etc. for an operationally reliable guidance is generated by spring units 35, as shown in FIG. 9 for the guide roller 17.

Cross members 36a, 36b are fastened on the chassis parts 31a, 31b with laterally projecting arms, on which the vehicle body 18 is supported via air springs 37, above the axles of the running wheels 11. The deflections which are carried out by the cross members 36a, 36b during pivoting together with the chassis parts 31a, 31b are compensated by the air springs 37 with respect to the vehicle body 18.

The vehicle body 18 is secured in the longitudinal and transverse directions by means of links 38, the free ends of which are connected to a component 39 arranged on the underside of the vehicle body 18 via a universal joint seated on a common axis. The air springs 37 therefore only transmit vertical forces from the vehicle body 18 to the articulated trolley 30, while the horizontal forces are transmitted from the vehicle body 18 to the articulated trolley 30 or vice versa by acceleration, braking and cornering via the components 39 and the links 38.

In the exemplary embodiment described, the wheels 11 have a wheel track of 640 mm. The width over the outside of the wheel tires of the wheels 11 is approximately 890 mm. With a width of the vehicle body of 2300 mm, based in each case on this width, there is a relative wheel track of only approx. 28% and a relative outside wetness over the wheels 11 of a pair of wheels of only approx. 39%, so that the chassis carrier 1 is kept correspondingly small can.

In a modification of the described embodiment, it is possible to design a vehicle with bogies, the bogies being preferably controllable or steerable with two axles with running wheels each of two upper and lower pairs of guide rollers.
