Rotary leadthrough for a vehicle

A rotary joint for supplying fluid to a pressure chamber that is disposed between a rotatable component and a stationary component of a vehicle, the rotary joint comprising:

• a seal carrier having at least one channel for a fluid connection to the pressure chamber, wherein at least two axially spaced apart sealing rings are disposed on the seal carrier for a static sealing of the at least one channel;
• at least one sealing element non-rotatably disposed on the seal carrier and configured to form an axial seal with a ring element that is non-rotatably connected to the rotatable component and a radial seal with the seal carrier to at least partially seal the pressure chamber;
• and
• wherein the at least one sealing element is configured to bear on the ring element when pressure is built up in the pressure chamber and the at least one sealing element has means for reducing an axial pressure exerted on the ring element;
• wherein the at least one sealing element has an axial region with a circumferential sealing lug that bears radially outwardly directly on the seal carrier to at least partially seal the pressure chamber;
• and
• wherein a first axial length of the circumferential sealing lug is less than half of a second axial length of the at least one sealing element.
