Gap bridging and method of operation

gap filling

Technical area

The invention relates to a gap bridging for a

Rail vehicle for bridging the gap between a passenger compartment floor and a platform and a method for operating this gap bridging.

State of the art

Gap bridging is used in modern rail vehicles to allow passengers a comfortable entry and exit and in particular the danger through the gap between the passenger compartment floor and the platform to

minimize. This gap has a width of about 100 mm in typical subway lines, but can also be up to 300 mm, for example, in the case of platforms climbing on a curved track. This variance of the gap dimensions represents a special one

A source of danger, since the passengers would have to be aware of each entry and exit of the current platform gap, which is often not possible in high passenger numbers. To bridge this platform gap can

Gap bridging be used, which usually include a sliding plate mounted, which is powered by the vehicle pushed out. For larger gap widths, this plate and its storage are very massive, so that the space requirement increases and thus such

Gap bridging only more complicated and under Impairment of the car body can be provided in the door area. With so-called folding / Schiebetritten this problem can be partially solved because such a pivotally mounted lever supports the plate from below and thus significantly reduces the forces on the storage of the plate. Such folding / sliding steps therefore require less space and can in the entry area of a

Passenger rail vehicle without changes to the

Car body structure can be used, with at the

Installation position of this gap bridging simply the

conventional floor construction removed and through the

Gap bridging is replaced. The kinematics of this

Gap bridging in the form of a folding / sliding step, however, requires that, when the plate is extended far, it lowers at its edge on the platform side, thus creating a step to the platform. In addition, a widely extended plate on a steep slope in the direction of the car interior. These properties make gap bridging in the form of a folding / sliding step unsuitable for larger platform gaps.

DESCRIPTION OF THE INVENTION The invention is therefore based on the object, a

Gap bridging in the form of a folding / Schiebetritts and provide a method for operating this gap bridging, which is suitable for larger platform gaps and in which in particular the difference in height between a platform and the platform side edge of the treadplate is minimized at large outward distances. The task is accomplished by a gap bridging with the

Characteristics of claim 1 and a method according to claim 8 solved. Advantageous embodiments are the subject

subordinate claims.

The basic idea of the invention according to a

Gap bridging for a rail vehicle for bridging the gap between a passenger compartment floor and a

Platform built, which one horizontally sliding

mounted tread plate and a pivotally connected to the tread plate by means of a hinge pivot arm comprises, wherein the pivot arm is provided at its end facing away from the joint with a vertically displaceable pivot joint. As a result, the advantage can be achieved to build a gap bridging in the form of a folding / sliding step, which is flexible to the particular structural conditions of

Platforms adapted to establish entry levels of treadle. In particular, at each approached platform a specific, optimized for this platform

Height of the platform side edge of the treadle be set at each different extension distance of the footboard, so that the passenger finds the same comfort at each platform. Furthermore can with objective

Spaltüberbrückung also over the length of a train, or over the length of a vehicle at each exit a different extension be realized, the height of the platform side edge of the tread plate always has the same level difference to the platform edge. This is especially important for platforms along railroad tracks. According to the kinematics of a gap bridging in the form of a folding / sliding step is designed so that the lower pivot point of the pivot arm is displaceable in its height, relative to the track level or the platform. Solcherart can be prevented at further extended tread a lowering of the platform side edge of the tread plate, since while the lower pivot point can be moved upwards. Here is the movement of the treadle of the

Displacement of the lower pivot point independently and both movements can be performed substantially independently of each other. At most, the mobility of the lower pivot point at low extension distances of

Tread plate limited by the risk of collision of the tread plate with cladding components, such as a cover plate.

The pivot point (pivot, hinge) of the pivot arm is slidably mounted in a certain length along a vertical axis. The exact design of the

required length section is based on the

Given geometry of a gap bridging and the

Extension of the footboard and the required

predeterminable height range of the platform-side edge of the footboard.

Advantageously, an adjustment of this

Anlenkpunkts by means of an electric power drive, for example by means of a threaded spindle.

In a further development of the invention, it is proposed to apply a restoring force to the pivot arm, preferably by means of a spring element, which the

Swivel arm tries to move to its rest position (retracted tread plate). This restoring force causes a Support the provision of the tread plate and the

Swivel arm in its retracted rest position.

According to the tread plate is mounted horizontally pushed, and preferably with a power drive

equipped, by which they between a rest position (retracted) and any number of different

extended position is displaced. In such a way, the optimal extension distance can be provided for different structural conditions within a railway line. Typically, an extension of the tread plate takes place until either the maximum extension distance is reached or the tread plate collides with the platform, wherein the

Power drive is switched off.

In this case, the tread plate is mounted in a sliding guide, wherein the carriage-side end of the tread plate is guided and the platform side end is free to move, so that it is supported by the pivot arm. The swing arm transfers the majority of the load on the tread plate

Weight forces, the sliding guide can thus be made very compact.

In this way, the advantage can be achieved that a gap bridging according to the invention can be made so flat that it has the same thickness as a surrounding floor structure. Thus, a gap bridging without changes to the

Body structure, in particular the door sill side beams are installed. It is advantageous, the tread plate with a sensor for determining the distance to a platform or to

To provide identification of a touch of the platform.

This sensor can be based on the capacitive measuring principle or optically detect the distance (infrared sensor) or mechanically contact electrical contact

actuate. By means of this sensor, the horizontal

Distance of the platform side edge of the tread plate can be determined, or it can additionally or alternatively, the vertical height difference of the platform edge side of the tread plate are determined to the edge of the platform.

Advantageously, a control device is provided which comprises means for operating the power drives for the tread plate and the vertical displacement of the pivot point of the pivot lever, for example corresponding

Power and protection electronics. Furthermore, the

Provide control device for the reception of signals from a sensor. By means of this signal, a signal proportional to the distance between the platform edge of the footboard and the platform is transmitted to the control device. An included in the control device

From the information supplied to it, the arithmetic unit determines a specific combination of extension distance of the tread plate and position (displacement) of the lower articulation of the treadle

Swivel arm. The the control device zugeleiteten

Information may include: signal received from the sensor, describing the distance of the platform-side edge of the treadplate to a platform, or the difference in height to the platform, the position of the train in the route network (current stop), position of the carriage in the train, position of the exit in a car, loading condition of the car.

In this case, in the control device, a data memory

be provided, in which the applicable for each stop combination of extension of the tread plate and position (displacement) of the lower linkage of the swing arm is stored. In particular, it is advisable to store the position of the gap bridging associated entry in the train in the data storage and for the determination of the respective combination of extension of the tread plate and displacement of the lower linkage

consulted. In this way, applications of stops arranged in curves can be taken into account, in which different extension distances of the gap bridging at entrances close to the end faces opposite the carriage center

Entrances are required.

This data can be stored invariably in the data memory or be determined continuously in the course of driving by processing the sensor signal.

The last embodiment provides a continuous

Self-learning system, which increases the precision of the control of the footboard and the swivel arm and thus increases passenger comfort. Furthermore, thereby the advantage can be achieved, even with a failure of the sensor, the gap bridging continue to operate, where

at most a slightly reduced precision of

Positioning of the tread plate occurs. In this case, the control device accesses the values stored in the data memory for extension distance and vertical positioning of the pivoting joint and operates the gap bridging in a controlled, uncontrolled operating method.

A data connection to a train control is preferably provided, via which the control device information about the position of the train in the route network, the current load state of the car and the required extension and retraction commands and a state feedback of the

Gap bridging to the train control can be transmitted. It is particularly important that the Operating sequence gap bridging - door opening can run correctly and in particular when extended

Gap bridging the vehicle can not start.

In this case, the data connection can be made to a train control by means of certain control signals or as a transmission of data telegrams, for example in the manner of the Internet

Be realized protocol.

In a further development of the invention, a manually operated emergency drive is provided by means of which the

Drivers can bring a gap bridging invention in its retracted rest position when the drives or the controller should fail. In this way, the vehicle can continue to operate, possibly with a locked entry point.

In a further development of the invention, it is advisable to equip the gap bridging with a device for preventing the ingress of dirt (scraper). Here is a cover plate above the footboard in the area of

Provide passenger compartment floor, said cover plate is provided at its platform edge side with a scraper. This cover plate has substantially the same

Height level as the surrounding vehicle floor, so that in the car interior caused by the gap bridging level differences, in particular no steps are required. At the platform edge of this cover plate a scraper is to be arranged, which closes the passage space side gap between the cover plate and the tread plate when retracting the tread plate or substantially reduced, so that foreign bodies not, or only up to a certain size in the space under the

Cover plate can penetrate. It is particularly advantageous if the scraper touches the tread plate and the contact force is at least enhanced by an elastic element.

For example, rubber lips, brushes or metal strips with friction-reducing supports can be used as scrapers.
