Wheel Drive having a Rotary Union

摘要

A wheel hub drive with a planetary transmission includes a wheel hub rotatably mounted on a fixed component and at least one fluid-carrying passage. The fixed component is configured to receive a tire with a gaseous filling. The at least one fluid-carrying passage extends indirectly as far as the tire through the fixed component in order to regulate the gas pressure in the tire. An annular rotary union defines at least a portion of the at least one fluid-carrying passage and is configured to connect the fixed component fluidically to the tire. The annular rotary union is arranged axially between the fixed component and the rotatably mounted wheel hub.

1. A wheel hub drive having a planetary transmission, comprising:
a fixed component; a wheel hub rotatably mounted on the fixed component and configured to receive a tire with a gaseous filling, the fixed component defining at least one fluid-carrying passage that extends indirectly as far as the tire through the fixed component so as to regulate the gas pressure in the tire; and an annular rotary union defining at least one fluid-carrying passage configured to connect the fixed component fluidically to the tire, the annular rotary union arranged axially between the fixed component and the rotatably mounted wheel hub.
