Title
(EN) WELDING OF TRANSFER RING ON ROUND TUBE
(FR) SOUDURE D'ANNEAU DE TRANSFERT SUR UN TUBE ROND
Abstract
(EN) A triple tube shock absorber includes a pressure tube, a reserve tube and an intermediate tube. The intermediate tube is disposed between the pressure tube and the reserve tube. A control valve is in communication with the intermediate chamber. The control valve engages a transfer ring which has a saddle shaped surface that mates with the outside surface of the intermediate tube. A triangular shaped weld bead also has a saddle shape to engage the outer surface of the intermediate tube. The weld bead has a triangular shape to facilitate capacitance discharge welding of the transfer ring to the intermediate tube.
(FR) Selon la présente invention, un absorbeur de chocs à triples tubes comprend un tube de pression, un tube de réserve et un tube intermédiaire. Le tube intermédiaire est disposé entre le tube de pression et le tube de réserve. Une vanne de commande est en communication avec la chambre intermédiaire. La vanne de commande vient en prise avec un anneau de transfert qui a une surface en forme de selle qui s'accouple avec la surface côté extérieur du tube intermédiaire. Un cordon de soudure de forme triangulaire a également une forme de selle pour venir en prise avec la surface extérieure du tube intermédiaire. Le cordon de soudure a une forme triangulaire pour faciliter une soudure de décharge de capacité de l'anneau de transfert au tube intermédiaire.
