PASSENGER RAIL VEHICLE TECHNICAL AREA

The invention relates to a passenger rail vehicle.

STATE OF THE ART

To bridge the gap between a platform and the passenger compartment floor of a rail vehicle so-called sliding steps, gap bridging or ramps are often used. These generally include a tread surface 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 or as a folding or tilting movement. The height of the platform above the upper level of the rail is specified in specific standards (UIC, TSI, GOST). In particular, the GOST standard, which is essentially valid for Russia, specifies very different level differences between rail top edge and platform level. According to GOST, this difference can be either 1100mm (commonly used in urban stations) or 200mm (common in bus stops in rural areas). The norms valid for Europe provide for a level difference between these values. 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 aforementioned boarding aids (sliding steps, gap bridging and ramps) are exposed to environmental influences, depending on the 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 its mobility (icy) folding step can be made with the drive means (electric or pneumatic actuators) often no longer free and must be manually de-iced. 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.

Entrances of rail vehicles are known from the prior art, EP0641701A1, which are suitable for use at different high platforms, with special retractable steps are provided for each entry level. However, using this solution is not possible under icing conditions.

In the document US 2002092240A1 a rail vehicle door is presented, which should facilitate the entry of two different platform levels. In this case, a flap is provided, which bridges the entry levels, so that the passengers can reach a higher platform. However, this solution can serve only two different platform levels. A solution very similar to the last-mentioned document is disclosed in US Pat. No. 3,724,396A, wherein the access is adapted to only two different platform levels. A further possibility to be able to serve different platform levels is shown in the document JP 55-114758U, with steps being adjustable in height by means of a parallelogram guide. 1/14 Austrian Patent Office AT512 012B1 2014-04-15

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.

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

According to the basic idea of the invention, a passenger rail vehicle is set up with four different entry levels, wherein a folding step for a first entry level is provided at an entry of this passenger rail vehicle, 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. In this case, the first entry level is lower than the second entry level and this second entry level is lower than the third entry level, and the third entry level is lower than the fourth entry level measured from the top of the rail.

As a result, the advantage can be achieved to be able to build a passenger rail vehicle, which offers a substantially constant entry comfort at four different entry levels.

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 a can muster the necessary high forces, by means of which the mobility can be restored especially in icing. 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.

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.

To generate 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. As a result, an actuation of the folding door in case of failure of the electric pump drive is possible. Likewise, only a manually operated pump can be provided, which is advantageous in particular for rail vehicles which start only to a small extent stations that require this lowest first entry level.

To further increase the snow and icing safety of the folding step can be carried out so that a tread plate is disposed on a substantially vertically arranged 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 position of use and back. Thus, the possibilities for snow and ice approach are significantly limited, since only in the field of implementation of the drive rod located through the car body snow and ice approach can hinder the mobility. At this point, however, the braking torque produced by this snow and ice formation can be more easily overcome than with conventional folding steps.

The sliding step for use in the second entry level is exposed to the 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 to be expected. 2/14 Austrian Patent Office AT512 012B1 2014-04-15 [0016] The drive of the sliding step takes place by means of the conventional electric or pneumatic drives. It is advantageous, in particular when a hydraulic drive is provided for the folding step, to use a hydraulic drive even for the sliding step, since in this way the outlay for the routing of different fluid media can be reduced.

The third entry level is formed by the usual staircase in the entry area of the passenger rail vehicle.

The inventively provided hinged ramp for the fourth and highest entry level comprises in a first embodiment, a first and a second tread plate, which are pivotally connected to each other by means of a hinge and wherein this hinged ramp stowed in the rest position (when not in use) in the boarding area of the passenger rail vehicle is. In this rest position, the folding ramp is in a vertical position, the two tread plates are folded. In this case, the folding ramp can be arranged so that it does not narrow the entry area when not in use, so that when using the folding or Schiebetritts for the 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 [0020] - Unlocking the hinged ramp in the rest position. It is advantageous, the

To provide unlocking by means of a tool, e.g. a square key to prevent operation by unauthorized personnel as possible.

- Pushing the hinged ramp in the entrance area of the rail vehicle.

In this case, a linear sliding device according to the invention is provided which allows a horizontal sliding of the two (still folded) foot plates in the carriage longitudinal direction. The hinged ramp is thereby pushed substantially in the middle of the entry area, or the entry stairs.

[0022] Folding over the two tread plates. The two (still folded) Trittplat th are placed in this step in a horizontal position, this includes the first tread a joint 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 equipped 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 a smaller amount of force. This spring device relieves the operator of a large part of the dead weight of the two tread plates.

- Unfold the second tread plate. In this case, the second tread plate which is connected to the first by means of a pivot joint is opened and bridged the gap between the platform and the rail vehicle. Such is the hinged ramp in position of use.

In a further development of the invention, a handrail is provided in the entrance area. This handrail is arranged when not in use the hinged ramp, ie at rest, in front of the inner lining. This makes it necessary to equip the handrail with a pivoting device, which makes the handrail swing out during the operation of the hinged ramp from the range of movement of the folding 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, before and after the above-described operating steps to carry out corresponding operating steps for the handrail.

The operation of the folding ramp is preferably done manually. However, it is possible to engage and disengage with the assistance of appropriate actuators and control devices.

Another embodiment of the hinged ramp provides that perform both tread plates pushed into each other. 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 sliding device is preferably carried out manually, for example by means of a manually operated rack and pinion drive.
