Description
L'invention concerne les amortisseurs de chocsThe invention relates to shock absorbers
comprenant des ressorts à boudin de compression. comprising compression coil springs.
Pour de tels amortisseurs, dans lesquels un piston est logé à glissement dans un cylindre et dans lesquels un ressort à boudin entourant la tige du piston s'applique contre le cylindre, le siège du ressort à boudin est normalement fixe. En particulier, quand le siège du ressort est fixé à un élément d'extrémité vissé dans l'extrémité d'un tube, la partie vissée de l'élément d'extrémité est conçue de telle manière qu'elle est encore plus vissée par la torsion s'établissant quand le ressort a boudin est comprimée Il en résulte que des copeaux métalliques sont produits par la friction entre l'extrémité incurvée du ressort à boudin et le siège du ressort, du fait du mouvement relatif provoqué par la torsion résultant de la compression, et ces copeaux colmatent les orifices à' huile, réduisant ainsi l'effet d'absorption de choc. En outre, le ressort à boudin et la surface interne du tube de l'amortisseur sont en contact l'un avec l'autre, quand le premier s'évase vers l'extérieur sous la compression, ayant For such dampers, in which a piston is slidably housed in a cylinder and in which a coil spring surrounding the piston rod is pressed against the cylinder, the seat of the coil spring is normally fixed. In particular, when the spring seat is attached to an end member screwed into the end of a tube, the screwed portion of the end member is designed such that it is further screwed by the The result is that metal chips are produced by the friction between the curved end of the coil spring and the seat of the spring, due to the relative movement caused by the twisting resulting from the rotation of the coil spring. compression, and these chips clog the oil ports, thereby reducing the shock absorption effect. In addition, the coil spring and the inner surface of the damper tube are in contact with each other, when the first flares outward under compression, having

Selon l'invention, ces inconvénients sont éliminés grâce au fait qu' au moins un des sièges à ressort pour les extrémités du ressort à boudin est rotatif au moyen d'un élément According to the invention, these disadvantages are eliminated by the fact that at least one of the spring seats for the ends of the coil spring is rotatable by means of an element

Les éléments 6 àa basse friction ont la fonction de réduire la friction de roulement,et ils ontpar exemplela forme de roulementsa billes ou à rouleaux qui sont logés de manière à tourner dans des trous ou évidements 8 conformés dans un cadre de support ou cage 7 en forme d'anneau,. Il en résulte que le siège àa ressort 5 coopérant avec ces éléments à base friction peut tourner avec l'extrémité du ressort à' boudin 1, grâce à la friction de roulements qui provient des éléments 6 à basse friction, en accord avec la torsion qui The low-friction elements 6 have the function of reducing the rolling friction, and they have for example the shape of ball bearings or roller bearings which are housed so as to rotate in holes or recesses 8 shaped in a support frame or cage 7 in ring shape ,. As a result, the spring seat 5 cooperating with these friction-based elements can rotate with the end of the coil spring 1, thanks to the friction of bearings which comes from the low-friction elements 6, in agreement with the torsion which

Une structure similaire pour la réception du ressort peut aussi être appliquée au siègede ressort à l'autre extrémité (c'est-à-dire l'extrémité du cylindre) du ressort à A similar structure for receiving the spring may also be applied to the spring seat at the other end (i.e. the end of the cylinder) of the spring.

mités du ressort à boudin sont conçus tel que décrit. The flange spring is designed as described.
Il résulte de la réduction de la friction entre le ressort à, boudin et le siège ou les sièges que la production de copeaux métalliques et la déformation du ressort jusqu'au contact du tube sont évitées, de sorte que les performances fonctionnement de l'amortisseur de chocsselon l'invention peuvent It results from the reduction of the friction between the coil spring and the seat or seats that the production of metal chips and the deformation of the spring until the contact of the tube are avoided, so that the performance of the damper operation shocksaccording to the invention can
