DE202005004885U1 - Floor education with floor plate in the driver's cab of rail vehicles - Google Patents

Abstract

The floor panel (1) of a driver cabin is divided into transverse segments (2) covered in protective film (3). Some of the segments function as guide segments (2A), while the other segments function as evacuating segments (2B). When front collision acts on the floor panel, the guide segments aid the evacuating segments to stack up on the rear. The protective film is supplied from a roll under the floor panel or cut to a length from above the panel.

Description

The The invention relates to a floor education with floor plate in the driver's cab of Rail vehicles.

at Collision-proof rail vehicles become deformation zones on the vehicle arranged. Due to the dynamics of a train must be a large part the collision energy at the vehicle tip, especially in the undercarriage be absorbed. For vehicles with a short tip - actually in almost all vehicles - is It required a part of the cab in the energy absorbing Involve deformation. For the driver is thereby provided a hardly deformable survival space, while the rest of the cab deformed more or less controlled.

From the DE 198 17 860 A1 For example, a safety device for drivers of rail vehicles is known, which consists of a head carrier upstream collision protection device of known design, a subsequent to the head support crumple zone in the area of the driver's cab, a remote, a seat frame and a driver's seat. The head support, the Rammschutzkonstruktion, the seat, the seat frame and the driver's seat are in such operative connection with each other that they should not change their position relative to each other in a risk to the driver on deformation of the crumple zone. The head support, the impact protection construction, the driving desk, the seat frame and the driver's seat are connected to one another in such a way that the said components are displaced together in the direction of the passenger compartment during deformation of the crumple zone. The seat frame and the seat of the driver are so far raised compared to the height level of the crumple zone, that on the one hand deform the crumple zone underneath the seat unhindered and on the other hand, an unhindered longitudinal displacement between the seat frame and crumple zone is made possible. The seat is so limited in its design relative to the driver's desk slidably provided that the driver can not be trapped between the driver's desk and seat.

From the FR 2 747 633 A1 For example, a car body structure with a cab is known which can progressively absorb deformation energy in the end regions, with the direction of propagation of the deformation being controllable during a shock. For this purpose, the car body structure has two energy-absorbing zones, formed of solid or exchangeable energy-absorbing elements, with different mechanical resistance properties for plastic, dynamic deformation. The interior, in particular the floor panel plays no role in the safety consideration.

The floor in the cabin, when deformed, constitutes a plate which is compressed in its plane when subjected to a sufficient longitudinal pressure, as in the case of a collision case of sufficient strength. This leads to buckling and finally breaking the plate. Since the plate is generally made of brittle, layered material, the floor will break according to a random pattern. The resulting, sharp-edged fragments can lead to dangerous injuries to the driver in the legs. A risk of injury is given especially in splintering materials such as wood. Since so far in the concepts for passive safety only the deformation behavior of the non-equipped body shell is considered (see above DE 198 17 860 A1 and FR 2 747 633 A1 ), the problem has not been considered in previous designs.

Of the Invention is therefore based on the object, a floor education in the driver's cabin rail vehicles such that the floorboard in the driver's cabin involved in the security concept and an improvement the behavior of the floorboard in terms of their hazard potential for persons in the driver's cabin is reached.

According to the invention this Problem solved by the features of claim 1.

Advantageous embodiments The invention will become apparent from the dependent claims.

One significant advantage of the solution is the achievement of a controlled collapse / coiling or generally a shortening, so that the ground area is deformed in a controlled manner in the event of a collision is and does not splinter uncontrollably. The risk of injury, especially in the leg area for Staff is reduced.

in the The invention is explained in more detail below with reference to an exemplary embodiment. In the associated Drawing shows:

1 a floor structure according to the invention with segments in side view in the unbroken state;

2 a floor structure according to the invention with segments in side view in the acted upon by the vehicle end state in the event of a collision with sufficient energy;

3 a further embodiment of the invention with below the rear guide segment ordered collection box for clearing segments and retraction device for the protective membrane;

4 an alternative solution with foldable Räumsegmenten in a schematic representation in side view in normal position (unfolds) and

5 the solution acc. 4 in the collapsed state (folded).

1 shows the basic design of a floor education according to the invention with floorboard 1 for rail vehicles. The largely flat floorboard 1 is in several segments 2 divided educated. In the front and rear area (with respect to the vehicle longitudinal direction) of the floorboard are guide segments 2a arranged. In between are strip-like Räumsegmente 2 B arranged substantially transversely to the longitudinal axis of the rail vehicle. The clearing segments 2 B are between the leading segments 2a arranged in a plane in the vehicle longitudinal direction one behind the other, with their Längsseiten- or cutting edges of the position of the Räumsegmente 2 B following within the vehicle, are oriented substantially in the vehicle transverse direction. Small angles deviating from the transverse direction or swept divisions are also to be encompassed by the term "substantially in the vehicle transverse direction".

Directly above the segments ( 2 ) towards the driver's compartment is a protective membrane ( 3 ) arranged, whereby upwards to the driver's room, the segments 2 through an impermeable protective membrane 3 are covered.

Every clearing segment 2 B is at its two longitudinal edges (arranged substantially transversely to the vehicle transverse direction) with such inclined longitudinal side surface 4 designed that a pushing up or pushing a front Räumsegmentes 2 B on a arranged behind this Räumsegment 2 B over the inclined longitudinal side surface 4 is possible. Likewise, the leading segments 2a at the clearing segments 2 B facing longitudinal side surfaces 4 for triggering or for effecting the process "longitudinal displacement or pushing or pushing" suitable longitudinal side surfaces 4 on.

In the rear of the driver's compartment below the rear guide segment 2a can be a collection box 5 for the longitudinally spaced segments 2 B be provided. Also, in the rear area a retractor 6 for the protective membrane 3 to be ordered ( 3 ).

If there is a collision, in which the longitudinal forces exceed a predetermined height, it comes to the stress of the divided floor panel 1 in the plane and the clearing segments 2 B shift in the direction of impact ( 2 ). The shock-facing, front guide segment acts on it 2a on which the driver's seat 9 is attached, the first clearing segment 2a with its longitudinal side surface that of the adjacent Räumsegmentes 2a and this clearing segment 2 B applied in the same way its adjacent, underlying clearing segment 2 B , In the same way, the other clearing segments 2 B acted upon and moved in the vehicle longitudinal direction. The clearing segments 2 B are in this process as a whole, depending on the angle of inclination when forming a stack on top of each other or pushed together.

The vertical arrangement of the Räumsegmente 2 B can be characterized by mechanisms as described herein by inclined planes and gliding or by folding over joints (in 4 and 5 shown) or rolling up (not shown) associated Räumsegmente 2 B be achieved. 5 shows the articulated Räumsegmente 2 B with protective membrane 3 in a quiet location, 5 this training in the collapsed state after Längsbeaufschlagung with humpback through the protective membrane 3 ,

The driver's desk 10 remains by its fixed arrangement before or at the front guide segment 2a also in case of collision at the same distance to the driver's seat 9 ,

The protective membrane 3 serves to protect the staff, especially the lower extremities. When layering the Räumsegmente 2 B forms the protective membrane 3 For injury-relevant parts of the floor an impenetrable upper end. Thus, the layering of the clearing segments leads to blunt humps, but not to exposed, pointed floor parts or splinters.

As a rule, throws the protective membrane 3 In the case of deformations, only wrinkles of one type do not endanger the leg area of the personnel.

If the wrinkling can not be desired or accepted, the shortening of the protective membrane can be 3 in the vehicle longitudinal direction by the already mentioned above retraction 6 , z. B. cause by a role. Also is a movement of the piled-up clearing segments 2 B in the aforementioned collection box 5 possible. In addition to curling is alternatively a targeted folding of the protective membrane 3 possible.

If installations remove the protective membrane 3 in the event of a collision hinder, can also be provided, the protective membrane 3 when retracting to cut. This is a cutting device 7 (Knife) at a suitable location, eg the leading segments 2a and / or to place in the rear of the driver's compartment.

The above principle can be used for floorboards 1 to be used, floating on the undercarriage 8th are stored. If there is a framework of girders under the floor, this can be adapted to the intended deformation requirements of the inner area.

All in all is achieved with the above-described invention that the driver's space over the Shell construction consideration in the safety concept for the passive Safety is included in rail vehicles.
