Rotary feedthrough as part of a tire pressure control system of a vehicle and vehicle equipped therewith

Abstract

A rotary feedthrough as part of a tire pressure control system of a vehicle, comprising a rotor assembly which can be connected in a torque-locking manner to an axle shaft of the vehicle carrying a wheel and a stator assembly which is arranged in a stationary manner in relation to the rotational movement of the rotor assembly. At least one sealed or sealable annular transmission channel is arranged between the rotor assembly and the stator assembly, through which channel, for the purpose of tire pressure control, a pathway for transmitting a gas from the stator assembly to the rotor assembly and/or vice versa is provided. The rotor assembly comprises a rotor part which is arranged at a radial distance from the outer surface of the axle shaft with the rotor-side pathways required for the rotary transmission of a gas, and a driver which can be connected to the axle shaft in a torque-locking manner and which is engaged in a floating manner in the radial direction for the transmission of a rotary movement from the axle shaft to the rotor part. The rotor part is centered with respect to the stator assembly via a bearing, which is arranged between the stator assembly and the rotor part at an axial distance from the driver.
