Abstract

Collision protection device for rail vehicles without side buffers at the front comprises energy-absorbing elements (1) arranged in the usual region of the side buffers and suitable for coming into contact with the buffer plate of the side buffers (2) of a second rail vehicle. The energy-absorbing element is designed as a pot (1a) whose opening faces forward in the impact direction and is filled with energy-absorbing material. The pot is fixed to a pressure piece (5) which is connected to the rail vehicle body over a stage (7) so that it can be longitudinally displaced relative to the rail vehicle body (6) to absorb additional deformation energy. Devices for the driver including his seat (8) fixed on the pressure piece are longitudinally displaced together with the pressure piece into the vehicle interior. <??>Preferred Features: The pot has a load-bearing casing forming a longitudinal guide and preventing lateral yielding of the penetrating side buffer.

Description

The invention relates to a collision protection device for rail vehicles according to the preamble of claim 1.

DE 198 17 861 A1 describes a collision protection device for rail vehicles known that a central buffer coupling with articulation via tear-off elements in the base frame, a guide shaft, an underride guard and has energy absorption elements. In doing so, the vehicle should Outstanding center buffer coupling in the event of a collision after action an impact energy that exceeds the energy consumption of the elastic elements, on the tear-off elements from the base frame and guided move back. The energy absorption elements are on the side of the central buffer construction arranged and extensive on the head girder and on the impact protection construction supported. When colliding with rail vehicles, the are equipped with side buffers, the energy absorption elements are predominant locally in the area of the penetrating page buffers depending on the Deformation resistance deformed. Below the head carrier or the Energy absorption elements is an underride guard in active connection with the Head carrier and the crash protection structure arranged, the front edge compared to the front edge of the energy absorption elements at least by Measure of the specified compression length of the energy absorption elements is reset.

DE 198 17 860 A1 describes a safety device for vehicle drivers of rail vehicles known from an upstream of the head carrier Collision protection device of known type, one adjoining the head carrier Crumple zone in the area of the driver's cabin, a driver's desk, one Seat frame and a driver's seat. The head girder, the crash protection construction, the driver's desk, the seat frame and the driver's seat are in such a way Active connection with each other that they deform when the crumple zone is deformed Do not change position to each other in a way that endangers the driver. The head support, the impact protection structure, the driver's desk, the seat frame and the driver's seat are connected to each other so that the above Components deform together in the direction of the crumple zone Passenger compartment to be moved. The seat frame and the driver's seat are opposite the level of the crumple zone so high that on the one hand deform the crumple zone underneath the driver's seat unhindered can and on the other hand an unimpeded longitudinal displacement between the seat frame and crumple zone is made possible. The driver's seat is in one configuration limited displaceable relative to the driver's desk that the The driver of the vehicle should not be caught between the driver's desk and the driver's seat can.

The invention has for its object a collision protection device further developed in such a way that, on the one hand, collision protection of rail vehicles equipped with a central buffer coupling are, in the event of a collision with rail vehicles with those with side buffers are provided, is improved and on the other hand the driver's workspace, especially his direct job, against the driver Dangerous deformations in the cab area caused by oversized Impact energy is protected more effectively.

This object is achieved by the features of claim 1 solved.

Advantageous embodiments of the invention are in the subclaims 2 to 7 specified.

The invention is explained below using an exemplary embodiment with reference to the drawing. Show it:

Fig. 6
a schematic diagram of the collision protection device acc. Fig. 5 after the response of the second stage for absorption of deformation energy with the vehicle driver's seat shifted longitudinally.

The collision protection device for rail vehicles has energy absorption elements 1 on both sides of the central longitudinal axis of the rail vehicle in Area of the side buffers 2 are arranged by full webs and on a longitudinally loadable Support 3 of the vehicle structure are supported.

The energy absorption element 1 is a pot which is open towards the front in the direction of impact 1a formed, which is filled with energy absorbing material 4. The Pot 1a is firmly connected to a pressure piece 5 via the support 3, which longitudinally displaceable with respect to the car body 6 with a second stage 7 is connected to the absorption of additional deformation energy or in Active connection is established. This second stage 7 is designed to be consumed of the energy absorption capacity of the energy dissipation element 1 and after Exceeding a given longitudinal force additional deformation energy to take up and dismantle from the longitudinal joint.

The devices for the driver are still on the pressure piece 5 including driver's seat 8 attached together with the pressure piece 5 are formed and arranged to be longitudinally displaceable inside the vehicle.

The pot 1a has a guide device 9 as an insertion aid. The guidance device 9 is expediently designed as a funnel, as shown in FIG. 3. The coat The pot 1a is designed to be sufficiently resilient, such that a longitudinal guide is formed, with which a transverse evasion of the buffer plate of an penetrating Side buffer 2 and thus lateral evasion or climbing the colliding rail vehicles prevented or at least significantly is difficult.

The pot 1a and / or the energy-absorbing material filled therein 4 can advantageously have a cross section that increases in the direction of impact exhibit. With such a design it is achieved that the buffer plate during impact first strikes a smaller cross-section and grows in the direction of impact Cross section a characteristic curve with increasing force curve is given.

This aforementioned basic effect is also in a variant shown in FIG. 2 with partial coverage of the buffer plate and the initial cross section of the Given material 4. This variant is for rail vehicles, in particular for city or regional railways, with the vehicle nose tapering towards the front or cross-sectional width in which the vehicle front is narrower than the mutual distance between the side buffers 2 of the full webs is executed. There with this design, the pot 1a would protrude laterally beyond the vehicle profile, can the jacket 10 surrounding the pot 1a be formed only partially, such that only one jacket section on the inside of the vehicle Trained side and is provided as a guide.

If the jacket 10 of the pot 1a is not significantly greater than the strength of the Mutual evasion or climbing must be formed of the ascending rail vehicles are otherwise ensured. However, there are known climbing protection devices from the prior art Technology available (e.g. DE 32 28 942 A1, US 3,197,039 or US 2,802,581).

The material 4 of the energy absorption element 1 is provided as a solid material. This material 4 can be cut from the solid and in the pot 1a or attached to the jacket 10, e.g. through adhesive techniques.

In terms of design, the area of the opening of the energy absorption element 1 or the pot 1a can be used to insert or apply a lamp.

4 to 6 are schematic diagrams of the collision protection device according to the invention showing the second stage 7 of the collision protection device shown in side view in section.

Fig. 4 shows the beginning of the application of the pot-like energy absorption elements 1 through the side buffers 2 of a second rail vehicle. Fig. 5 shows a representation of the collision protection device after penetration of the page buffer 2 in the energy absorption elements 1 and the beginning of the response the second stage 7 for energy absorption of additional deformation energy. Fig. 6 shows the collision protection device according to FIG. 5 after Addressing the second stage 7 for the absorption of deformation energy longitudinally displaced driver's seat 8.

In the event of a collision of the rail vehicle equipped according to the invention with a second rail vehicle with side buffers 2 come the buffer plates Side buffer 2 on the energy absorption elements which are essentially axially aligned with them 1 or pots 1a to the plant. Upon further penetration the side buffer 2 in the pots 1a is caused by the deformation of the in the pots 1a arranged energy absorbing material 4 reduced impact energy, wherein an uncontrolled deformation of the front area of the invention equipped rail vehicle is largely prevented.

After consuming the absorbency and the available Deformation path of the energy dissipation element 1 speaks the second stage 7 of the Collision protection device. This second stage 7 is - as already mentioned at the beginning Description mentioned - designed to exceed a predetermined Longitudinal force to absorb additional deformation energy from the longitudinal impact and dismantle.

Since the energy absorption elements 1 are firmly connected to the pressure piece 5 are, which in turn are longitudinally displaceable with respect to the car body 6 is connected via the second stage 7, the pressure piece 5 after exceeding the response force is shifted lengthways in the direction of impact. The second stage 7 applied and further impact energy reduced. Because on the pressure piece 5 also the facilities for the driver, including the driver's seat 8 are attached as an assembly, these are together with the Thrust piece 5 towards the rear towards the body 6 in the less endangered Area forcibly shifted, the facilities of the driver's cab against each other Remain substantially spaced and not in one of the vehicle drivers move dangerous way. In particular, the driver's desk remains spaced from the driver's seat and thus prevents the Driver.
