Abstract

The railway vehicle anti-telescoping device is used with a central coupler and excessive shock absorber. It is fitted by its centre (6), via the shock absorber, to the lower part of the underframe. The central coupler is carried on a cross piece. The front has a number of pyramid shaped projections in vertical and horizontal lines. The device is made up of three distinct parts (11), pivoted together, the central one fitting onto the underframe. The side parts are indirectly fixed by a pivot of adjustable length and include a shock absorber (14).

Description

La presente invention se rapporte a un dispositif de protection antigrimpement pour vehicules ferroviaires, en association avec un attelage central à amortisseur auquel fait suite un dispositif pour absorber les chocs trop intenses. The present invention relates to an anti-climb protection device for railway vehicles, in association with a central hitch with shock absorber which is followed by a device for absorbing too intense shocks.

Dans un dispositi de ce genre connu par la publication D-PS I 530 223, l'epaisseur des parois et la longueur du cylindre creux intérieur determlnent 1 intens i te des chocs pouvant être absorbes. Etant donne que les chocs qui agissent normalement sur l'attelage central doivent entre absorbes par le dispositif de traction et d amortissement qui lui fait suite, ce dispositif n'est adapte que pour les chocs et les tamponnages depassant 2inN. En consequence, ce dispositif est relativement lourd, et surtout long, ce qui limite les possibilites d'installation. In a device of this kind known from the publication D-PS I 530 223, the thickness of the walls and the length of the inner hollow cylinder determine 1 intensity i te of shock which can be absorbed. Since the shocks which act normally on the central coupling must be absorbed by the traction and damping device which follows it, this device is only suitable for shocks and buffers exceeding 2inN. Consequently, this device is relatively heavy, and above all long, which limits the possibilities of installation.

Dans la publication DE-PS I 912 049, il est par ailleurs propose de réaliser ce dispositif à double paroi afin que, à longueur egale, de plus grandes forces d'impact puissent autre absorbées. Or, on a constate qutaprès des chocs repentes à la limite de la capacite d'absorption du dispositif, celui-ci, lorsqu'il est monte sur le trajet cinétique des chocs, pressente une réduction de sa capacite d'absorption des chocs excessifs.Or, pour réaliser dans ces conditions une protection efficace des voyageurs , il est d'usage, en particulier dans les tramways et les véhicules de transport en commun a courte distance, de pourvoir cette surface frontale d'un dispositif de protection antigrimpement afin d'éviter lorsque deux vehicules se tamponnent. trop fortement, qu'ils s'accrochent l'un à l'autre.Cette protection antigrimpement est constituee par des barrettes individuelles, espacées entre elles et montees horizontalement sur toute la largeur de la face frontale des véhicules, Ainsi, dans le cas d'un tamponnage trop fort, les vehicules ne peuvent pas grimper, mais ils peuvent par contre se plier lateralement, de sorte que l'impact est absorbe par une déformation des parois latérales, qui sont relativement faibles. In publication DE-PS I 912 049, it is also proposed to make this double-walled device so that, at equal length, greater impact forces can be absorbed. However, it has been observed that after repentant shocks at the limit of the absorption capacity of the device, the latter, when it is mounted on the kinetic path of the shocks, senses a reduction in its capacity for absorbing excessive shocks. However, to achieve effective protection for travelers under these conditions, it is customary, in particular in trams and short-distance public transport vehicles, to provide this front surface with an anti-climb protection device in order to avoid when two vehicles clash. Too strongly, that they cling to each other.This anti-climb protection is constituted by individual bars, spaced between them and mounted horizontally over the entire width of the front face of the vehicles, Thus, in the case of 'A strong buffering, the vehicles can not climb, but they can on the other hand bend laterally, so that the impact is absorbed by a deformation of the side walls, which are relatively weak.

La présente invention s'est fixé pour but de réaliser un dispositif de protection antigrimpement en relation avec un dispositif du type spécifié ci-dessus qui empeche aussi les véhicules de dévier latéralement lors de l'absorption d'un impact trop intense. The present invention has set itself the aim of providing an anti-climb protection device in connection with a device of the type specified above which also prevents vehicles from deviating laterally during the absorption of an impact that is too intense.

L'invention atteint le but qu'elle s'est fixé en ce que le centre du dispositif de protection antigrimpement est fixé à une barre d'amortissement qui est fixée, avec interposition d'un dispositif de protection contre les chocs excessifs, a un cassis, et qui porte lia.:elage central par l'intermédi- aire d'une barrette, la surface frontale du dispositif de protection antigrimpement presentarlt une multiplicité d'éléments saillants pyramidaux alignés horizontalement et verticalement. The invention achieves the object that it has set itself in that the center of the anti-climb protection device is fixed to a damping bar which is fixed, with the interposition of a protection device against excessive shock, to a blackcurrant, and which carries lia.:elage central by the intermediary of a bar, the front surface of the anti-climbing protection device presentarlt a multiplicity of projecting pyramidal elements aligned horizontally and vertically.

En se référant aux dessins on voit un dispositif d'attelage central à amortisseur qui comprend une tête d'accouplement I et une barre de traction 2 qui, d'une manier classique, est pourvue d'un dispositif de traction et d'amortissement 3, ainsi que d'un dispositif déformable mécaniquement 4, qui a pour fonction d'absorber les chocs trop intenses. Referring to the drawings there is shown a central coupling device with shock absorber which comprises a coupling head I and a drawbar 2 which, in a conventional manner, is provided with a traction and damping device 3 , as well as a mechanically deformable device 4, which has the function of absorbing too intense shocks.

Parallèlement au dispositif d'attelage central est montée, à une certaine distance de celui-ci, sous le châssis inférieur 5, une barre d'amortissement 6 pouvant se deplacer axialement dans un guide -7 et qui porte, à l'une de ses extrémités, un dispositif de protection antigrimpement 8, tandis que son autre extrémité est reliée, par l'intermédiaire d'une contresurface 9, au châssis inférieur 5. Le dispositif d'attelage central est articulé à la barre d'amortissement 6 de façon à pouvoir pivoter horizontalement de telle manière que, dans sa position normale, la barre de traction 2 et la barre d'amortis sement 6 sont situées dam un meme plan central vertical du.Parallel to the central coupling device is mounted, at a certain distance therefrom, under the lower chassis 5, a damping bar 6 which can move axially in a guide -7 and which carries, at one of its ends, an anti-climb protection device 8, while its other end is connected, by means of a countersurface 9, to the lower chassis 5. The central coupling device is articulated to the damping bar 6 so as to be able to pivot horizontally so that, in its normal position, the pull-up bar 2 and the damping bar 6 are located in the same vertical central plane of the.

châssis 5, tandis que la surface frontale la de la tête d'accouplement 1 dépasse d'une distance prédéterminée a la surface frontale 8a du dispositif de protection antigrimpement 8, cette distance a correspondant à la profondeur de pénétration b du dispositif 4.chassis 5, while the front surface 1a of the coupling head 1 protrudes by a predetermined distance from the front surface 8a of the anti-climb protection device 8, this distance a corresponding to the penetration depth b of the device 4.

La surface frontale 8a présente une multitude aleié- ment saillants pyramidaux Il alignés en rangées et peut - comme représente sur la figure 5 - être composée de trois parties, ces différentes parties juxtaposées 8b, 8c et 8d étant reliées entre elles par des articulations 12.On remarque que l'élément de protection antigrimpement 8c est paral- lèle à l'élément du châssis portant la tête, tandis que les éléments de protection 8b et 8d sont en retrait, afin d'étire efficaces dans le cas ot le véhicule se déplace sur une pente, et forment ainsi un certain angle avec la partie 8c. L'élé- ment de protection antigrimpement 8c est fEé directement à la barre d'amortissement 6, tandis que les éléments de protection 8b et 8d sont articulés respectivement, par une barre d'amortissement 13 de longueur variable, qui est monté dans un dispositif de protection contre les chocs excessifs défor- mable 14, à la barre d'amortissement 6, de pPéféxence à la barrette 10 de celle-ci. Entre la barrette 10 et la contresurface 9, une protection contre les chocs excessifs 15 est incorporée dans la barre d'amortissement 6, dispositif dont la profondeur de pénétration C dans le cas d'une déformation, correspondant à l'espacement d entre la surface frontale Sa et la surface frontale du véhicule. The front surface 8a has a multitude of pyramidal projections II which are aligned in rows and can - as shown in FIG. 5 - be made up of three parts, these different juxtaposed parts 8b, 8c and 8d being connected together by articulations 12. It is noted that the anti-climb protection element 8c is parallel to the element of the chassis carrying the head, while the protection elements 8b and 8d are set back, in order to stretch effectively in the case where the vehicle is moving on a slope, and thus form a certain angle with the part 8c. The anti-climbing protection element 8c is directly connected to the damping bar 6, while the protective elements 8b and 8d are articulated respectively, by a damping bar 13 of variable length, which is mounted in a device deformable excessive shock protection 14, to the damping bar 6, from pÉféxence to the bar 10 thereof. Between the bar 10 and the counter surface 9, a protection against excessive shock 15 is incorporated in the damping bar 6, a device whose penetration depth C in the case of a deformation, corresponding to the spacing d between the surface frontal Sa and the frontal surface of the vehicle.

Les forces de tamponnage qui, normalement, agissent sur la tête d'aceouplement I sont absorbées par le dispositif de traction et d'amortissement 3. Dans le cas d'un choc ou d'un tamponnage trop intense, celui-ci est absorbé par la déformation du dispositif 4, ce qui a pour effet de déplacer le dispositif d'attelage central de telle manière que la surface frontale la ient se placer dans le même plan vertical que la surface frontale 8a (figure 2), Dans le cas de-l'appa- rition d'un second choc excessif, celui-ci agit à la fois sur le dispositif de protection antigrimpement 8, ainsi que sur l'attelage central et il est dirigé, d'une part directement et, d'autre part, par l'intermédiaire de la barrette- 10 à la barre d'amortissement 6 et, de là, au dispositif de sécurité contre les tamponnages excessifs 15. The buffering forces which normally act on the coupling head I are absorbed by the traction and damping device 3. In the event of an overly intense shock or buffering, this is absorbed by the deformation of the device 4, which has the effect of displacing the central coupling device in such a way that the front surface ient is placed in the same vertical plane as the front surface 8a (FIG. 2), in the case of- the appearance of a second excessive shock, this acts both on the anti-climb protection device 8, as well as on the central coupling and it is directed, on the one hand directly and, on the other hand , via the bar 10 to the damping bar 6 and, from there, to the safety device against excessive buffering 15.

La présence des éléments saillants 11 sur la surface frontale 8a a pour effet, dans le cas d'un tamponnage ou d'un choc trop intense, que les protections antigrimpement des véhicules en cause s s'accrochent mutuellement, évitant ainsi que ces véhicules puissent dériver soit vers le haut, soit latéralement.  The presence of the protruding elements 11 on the front surface 8a has the effect, in the event of a buffering or too intense shock, that the anti-seizure protections of the vehicles in question cling to each other, thus preventing these vehicles from being able to drift either upwards or laterally.
