Title
(EN) ROTARY FEEDTHROUGH ASSEMBLY FOR A TIRE INFLATION SYSTEM
(FR) ENSEMBLE PASSAGE ROTATIF POUR UN SYSTÈME DE GONFLAGE DE PNEU
Abstract
(EN)
Rotary feedthrough assembly (100) for a tire inflation system for a vehicle, the assembly (100) comprising: a stationary part (2) comprising a first section (16a) of a main fluid line (16) and a first section (17a) of a pilot fluid line (17); a rotatable part (5) rotatably mounted on the stationary part and configured to support a pneumatic tire, the rotatable part (5) comprising a second section (16b) of the main fluid line (16) and a second section (17b) of the pilot fluid line (17); a first annular seal chamber (8) radially disposed between the stationary part (2) and the rotatable part (5), the first annular seal chamber (8) providing fluid communication between the first section (16a) of the main fluid line (16) and the second section (16b) of the main fluid line (16); a second annular seal chamber (3) radially disposed between the stationary part (2) and the rotatable part (5), the second annular seal chamber (3) providing fluid communication between the first section (17a) of the pilot fluid line (17) and the second section (17b) of the pilot fluid line (17); wherein the first annular seal chamber (8) and the second annular seal chamber (3) are located on radially opposing sides of the rotatable part (5).
(FR)
L'invention concerne un ensemble passage rotatif (100) pour un système de gonflage de pneu pour un véhicule, l'ensemble (100) comprenant : une partie fixe (2) comprenant une première section (16a) d'une ligne de fluide principale (16) et une première section (17a) d'une ligne de fluide pilote (17) ; une partie rotative (5) montée rotative sur la partie fixe et configurée pour soutenir un pneumatique, la partie rotative (5) comprenant une seconde section (16b) de la ligne de fluide principale (16) et une seconde section (17b) de la ligne de fluide pilote (17) ; une première chambre étanche annulaire (8) radialement disposée entre la partie fixe (2) et la partie rotative (5), la première chambre étanche annulaire (8) assurant une communication fluidique entre la première section (16a) de la ligne de fluide principale (16) et la seconde section (16b) de la ligne de fluide principale (16) ; une seconde chambre étanche annulaire (3) radialement disposée entre la partie fixe (2) et la partie rotative (5), la seconde chambre étanche annulaire (3) assurant une communication fluidique entre la première section (17a) de la ligne de fluide pilote (17) et la seconde section (17b) de la ligne de fluide pilote (17) ; la première chambre étanche annulaire (8) et la seconde chambre étanche annulaire (3) étant situées sur des côtés radialement opposés de la partie rotative (5).
