Definitions

  • the invention relates to the suspension of a heavy component on a carrier, in particular a rail vehicle, which has a downwardly open wedge-shaped bed with two legs connected to the carrier, the component being non-positively and positively connected to the wedge-shaped connecting piece by means of a wedge-shaped connector corresponding to the carrier-side bedding Bedding is connected.
  • the invention is based on the problem of suspending a heavy component in such a way that all weight and acceleration forces are introduced into the carrier with a high degree of certainty. It can be assumed that the forces act in the vertical direction as well as in the longitudinal and transverse directions; in addition, vibrations, which can be caused both by a mechanical component and by irregularities of the tracks, must be taken into account especially while a rail vehicle is traveling.
  • a suspension is known from the "Handbook of Fastening and Joining of Metal Parts" published in 1956 by Mc Graw-Hill Book Company, page 542, B, in which a wedge-shaped connecting piece corresponding to this bedding is formed in a wedge-shaped bedding of a carrier which is open at the bottom of a component engages.
  • the carrier has a vertical slot opening into the bedding, through which the width of the bedding can be increased or decreased within the framework of resilient movements of the legs delimiting it.
  • this enables the connector to be inserted into the bed and, on the other hand, the connector can be clamped in the bed by means of a screw connection which is arranged transversely to the vertical slot.
  • the invention has for its object to design a suspension of the generic type in the simplest possible manner according to the problem described above and without the aforementioned disadvantages.
  • the wedge-shaped bedding is rigidly formed by rigid construction and rigid connection of the two legs to the support overall, the positive engagement of the connector in the bedding is achieved by vertical relative movement of the connector and the biasing force on the connector acts in a vertical direction downwards.
  • a further embodiment of the invention is that the dimensionally stable bedding extends in the longitudinal direction of the beam, with local, in at least one of the two legs of the bedding, recesses serving to insert the connectors are provided.
  • the exact fixing of the connecting pieces of the component at a respectively desired fastening location takes place in that the connecting piece, on its section lying in the dimensionally stable bed, via screws engaging in this section, which penetrate a support plate resting against the open end of the bed , is firmly clamped.
  • the support 1 shown in FIGS. 1 to 5, designed as a light metal extruded profile and which, with a support of the same type (not shown), forms a support pair for receiving a component 2, has a bed 1a open at the bottom on its lower longitudinal side, the bed 1a is wedge-shaped and is delimited by two legs 1b. According to FIG. 2, the bed 1a extends over the length of the carrier 1, which is only partially shown.
  • a recess 1c is formed at a weakly stressed point on the carrier 1, according to FIGS. 2 and 3, due to the omission of one of the two legs 1b.
  • the recess 1c serves to insert a connection piece 2a of the component 2, which is indicated in FIG. 2 and is shown in more detail in FIGS. 4 and 5, into the bedding 1a.
  • the portion of the connector 2a engaging in the bed 1a of the carrier 1 is also wedge-shaped, so that a positive connection is provided between the bed 1a and connector 2a.
  • a rectangular arm that penetrates the open end of the bed 1 a and is connected to the component 2 by welding is formed on this wedge-shaped section of the connection piece 2a such that - as FIG. 4 shows the longitudinal cross section of the connection piece 2a T- is shaped.
  • the lugs 4a encompass the outer surfaces of the two legs 1b of the bed 1a. Screws 3 guided through the support plates 4 each engage in the said wedge-shaped sections of the connecting pieces 2a, as a result of which these and thus the component 2 are clamped in place.

Claims (5)

1. Système de suspension d'une pièce constitutive lourde (2) à un support (1), en particulier d'un véhicule ferroviaire, présentant un logement dépouillé cunéiforme (1a) ouvert vers le bas et muni de deux branches (1b) reliées au support (1), la pièce constitutive (2) étant reliée au logement dépouillé (1a), mécaniquement et par concordance de formes, par l'entremise d'une pièce cunéiforme de solidarisation (2a) qui est réalisée en concordance avec le logement dépouillé (1a) situé côté support, caractérisé par le fait que le logement dépouillé cunéiforme (1a) est globalement configuré avec constance de forme grâce à une réalisation rigide et une solidarisation rigide à la flexion des deux branches (1b) avec le support (1), la venue en prise de la pièce de solidarisation (2a) dans le logement dépouillé (1 a), s'opérant par concordance de formes, étant obtenue grâce à un mouvement relatif vertical de cette pièce de solidarisation (2a), et la force de précharge appliquée à la pièce de solidarisation (2a) agissant vers le bas, dans le sens vertical.
2. Système de suspension selon la revendication 1, caractérisé par le fait que le logement dépouillé (1a) à constance de forme s'étendsur l'étendue longitudinale du support (1), des échancrures localisées (1c), servant à l'insertion des pièces de solidarisation (2a), étant prévues dans au moins l'une des deux branches (1b) du logement dépouillé (1a).
3. Système de suspension selon la revendication 2, caractérisé par le fait que les échancrures (1c) sont disposées, dans le logement dépouillé (1a) à constance de forme, dans des zones du support (1) soumises à de faibles sollicitations et à ferme distance du point de fixation considéré de la pièce de solidarisation (2a).
4. Système de suspension selon l'une des revendications 1 à 3, caractérisé par le fait que la pièce de solidarisation (2a) est bloquée à demeure, sur son tronçon encastré dans le logement dépouillé (1a) à constance de forme, par l'intermédiaire de boulons (3) qui pénètrent dans ce tronçon et traversent une plaque d'appui (4), appliquée contre l'extrémité ouverte du logement dépouillé (1a).
5. Système de suspension selon la revendication 4, caractérisé par le fait que la plaque d'appui (4) est dotée d'appendices (4a) qui ceinturent les faces externes des deux branches (1b) du logement dépouillé (1a).
