Patent ID: 11298988

Abstract:
A rotary joint assembly for a tire inflation system for a vehicle includes a stationary portion defining a first fluid passage. The stationary portion includes a support portion and having a first annular sealing face. The first fluid passage ending in the first annular sealing face. The assembly also includes at least one bearing and a rotatable portion rotatably mounted on the support portion by way of the at least one bearing. The rotatable portion defines a second fluid passage and has a second annular sealing face, the second fluid passage ending in the second annular sealing face. The rotatable portion defines an axis of rotation of the rotatable portion and a radial direction oriented perpendicular to the axis of rotation. The at least one bearing supporting an inner face of the rotatable portion, wherein the inner face of the rotatable portion faces toward the axis of rotation. An annular seal chamber is radially disposed between the first annular sealing face and the second annular sealing face and provides fluid communication between the first fluid passage and the second fluid passage. The at least one bearing and the annular seal chamber at least partially overlap along an axial direction oriented in parallel to the axis of rotation.
