Passenger rail vehicle 5

Technical area

The invention relates to a passenger rail vehicle. 10 State of the art

For bridging the gap between a platform and the passenger rear floor of a rail vehicle, 15 so-called sliding steps, gap bridging or ramps are often used. These generally include a tread which is movably supported and moved between a retracted and an extended position. This movement takes place in the simplest case as a sliding movement cder as a folding or tilting movement. The height of the platform above the upper level of the platform is specified in specific standards (UIC, TSI, GOST), with the GOST standard, which is essentially valid for Russia, specifying very different 25 level differences between the upper and lower rails

Platform level. According to GOST, this difference can be either 1100mm (commonly in urban stations) or 200mm (common in bus stops in rural areas). The standards valid for Europe 30 see one between these values

Level difference before. Thus, a rail vehicle can not offer the same entry-level comfort at every stopping point in cross-border traffic, since in each case other entry heights are to be overcome by the passengers. The 13/10/2011 15:23

No .: R425 P.004 / 026 201025635 m * t: • * entry-level aids (sliding steps, gap overpasses and ramps) are exposed to environmental influences depending on their concrete design. In particular ice and snow approaches can hinder the desired function. To remedy this, as far as possible, all components are arranged inside the car, but this is only possible to a limited extent, in particular in the case of folding steps, since the tread plate of a folding door must be located outside the car anyway.

A hindered in his mobility (icy)

The folding step can often no longer be made free with the drive means (electric or pneumatic drives) and must be de-iced manually. The use of a folding door is therefore particularly advantageous and in use, since by means of a folding door, the space between the folding steps of the right and left side of the car can be kept free for other installations. A sliding step, which performs the same tasks as a folding step has a space extending in the direction of the car axle space and would hinder the installation of equipment under the chassis. Furthermore, a sliding step would, taking into account the given building line, which is tapered inwards at this position, occupy the space in the car body and make further installations much more difficult.

Presentation of the invention

The invention is therefore based on the object to provide a passenger rail vehicle, which offers a substantially constant entry comfort at different platform levels, which remains unchanged even with aggravating environmental factors, especially icing and snowfall. 13/10/2011 15:23 2 No .: R425 P.005 / 026 5 201025635

The object is achieved by a passenger rail vehicle having the features of claim 1. Advantageous embodiments are the subject of the subordinate claims.

According to the basic concept of the invention, a passenger rail vehicle with four different Einetiegsniveaus, wherein at an entry of this passenger rail vehicle a folding step is provided for a first entry level 10, a sliding step is provided for a second entry level, a staircase is provided for a third entry level, and a folding ramp is provided for a fourth entry level. The first entry level is lower than the second entry level and second

Entry level lower than the third Einatiegsniveau, and the third entry level lower than the fourth Einatiegsniveau each measured from the top rail. 20 This is the advantage achievable, a

Passenger rail vehicle to build, which offers a substantially constant entry comfort at four different entry levels. 20 The inventively provided folding step is used at the lowest (first) entry level. Such a folding step is exposed to the environmental influences and ice and snow can be set in such a way that the required mobility is limited *. Therefore, an embodiment of the invention provides for the use of a hydraulic drive for the folding step, since such can apply the required high forces , by means of which the mobility especially in icing 3 13/10/2011 15:24 P.006 / 026

No .: R425 201025635

can be restored. These high forces can also be achieved with electric and pneumatic drives, but this complex and expensive gear are required, which can be omitted in a hydraulic drive 5.

A hydraulic drive further offers the advantage of being able to perform the hydraulic lines between the pump and the working cylinder largely arbitrary, which is particularly advantageous in confined spaces. For generating the hydraulic pressure common, electrically driven vane 'or gear pumps can be used.

An embodiment of the invention provides for the use of a manually operated pump. This also a 16 actuation of the folding event in case of failure of the electric Fumpenantriebs is possible * Also, only a manually operated pump can be provided, which is particularly advantageous for rail vehicles that start only a small extent stations that require this lowest 20 first entry level.

To further increase the snow and icing security of the folding step can be carried out so that a tread plate is disposed on a substantially perpendicularly arranged 26 drive rod and this drive rod is acted upon by means of a arranged in the car interior drive with torque. In this way, the tread plate is pivoted from a rest position into a service position and back. Thus, the possibilities for snow and ice accumulation are substantially limited, since only in the field of implementation of the drive rod through the car body located snow and ice approach can hinder the mobility. At this point, however, the 13/10/2011 15:24 4 No .: R425 P.007 / 026 201025635 «9

Snow and Gisansatz resulting braking torque are overcome more easily than conventional folding kicks.

Oer Schiebetritt for use with the second 6 entry level is exposed to environmental influences to a much lesser extent than the folding step. Due to the protected position of the mechanical components, no significant influence of the weather on the function is expected. 10 The drive of the sliding step takes place by means of the usual electric or pneumatic drives. It is advantageous, in particular if a hydraulic drive is provided for the folding step, to use a hydraulic drive even for the sliding step, since the expenditure for the routing of different fluid media can be reduced in this way.

The third entry level is formed by the conventional staircase in the entry area of the passenger television vehicle 20.

The inventively provided hinged ramp for the fourth and highest entry level comprises in a first embodiment, a first and a second tread plate 25 which are pivotally connected to each other by means of a hinge and wherein this hinged ramp is stowed in the rest position (when not in use) in Einetiegsbereich the passenger rail vehicle. In this rest position, the hinged ramp is in vertical position 30, wherein the two tread plates are folded. The foldable ramp can be arranged so that it does not narrow the entry area when not in use, so that when using the folding or sliding step for the 13/10/2011 15:24 5 No: R425 P.008 / 026 201025635 *

Passenger no difference to a vehicle without hinged ramp is recognizable. For this purpose, the hinged ramp is arranged in a recess of the inner lining.

The transition from the rest position to the position of use is done manually by means of the following operating steps - unlocking the hinged ramp in the rest position. It is advantageous to provide the unlocking by means of a tool, e.g. a square key to prevent operation by unauthorized personnel as possible. - pushing out the hinged ramp into the entrance area of the rail vehicle. Dabsi according to the invention a linear sliding device is provided, which allows a horizontal sliding of the two (still folded) tread plates in the carriage longitudinal direction. The hinged ramp is thereby pushed substantially in the middle of the entry area, or the entry stairs. - fold over the two tread plates. The two (still folded) tread plates are brought into a horizontal position in this operating step, to the first tread plate comprises a hinge at the junction with the linear slide device, which allows this pivoting movement. This joint at the point of connection to the linear slide device is preferably provided with a spring device (for example a torsion spring device), so that when the two tread plates are folded over, the operator only has to expend less force. This spring device relieves the operator of a large part of the dead weight of the two tread plates. 13/10/2011 15:25 6 Nr .: R425 P.009 / 026 201025635 - Opening the second tread plate. In this case, the second tread plate, which is connected to the first by means of a pivot joint and the gap bridged between the platform and the rail vehicle, such is the hinged ramp in the use position. In a further development of the invention, a handrail is provided in the entrance area. This handrail is arranged when the foldable ramp is not in use, ie at rest / in front of the interior trim. This makes it necessary to equip the handrail with a pivoting device, which swings out the handrail during the operation of the hinged ramp from the range of movement of the hinged ramp. The handrail can be fixed in the position of use of the folding ramp back to its original position, so that it can be used.

In this case, corresponding operating steps for the handrail are to be carried out before and after the operating steps described above.

The operation of the folding ramp is preferably done manually. A power-assisted folding and unfolding is possible with the use of appropriate actuators and control devices.

Another embodiment of the hinged ramp provides that run both tread plates into one another. In this case, the connection between the first and the second tread plate is to be equipped with a pushing device instead of by means of a pivoting joint. As a result, the advantage can be achieved to free the operator from the effort when folding the second tread plate. The drive of this pusher is preferably 13/10/2011 15:25 7 No .: R425 P.010 / 026 201025635

manually, for example by means of a manually operated rack and pinion drive. 5
