Abstract: An assembly supplies compressed air to a wheel of a vehicle. The assembly includes a wheel with a tire, a drive shaft for transmitting torque to the wheel, a wheel bearing on which the wheel in mounted in a rotationally fixed manner, and a toothing between the drive shaft and the wheel bearing. The wheel bearing is tensioned with the drive shaft by a bolt, wherein the bolt is arranged coaxially in relation to the drive shaft. An annular chamber of the wheel bearing is defined inside the wheel bearing and radially outside of the bolt. A compressed air through-opening is provided from the annular chamber of the wheel bearing in the direction of the wheel. A compressed air guide, leads from a compressed air source on the vehicle side into the annular chamber of the wheel bearing, from the annular chamber of the wheel bearing via the at least one compressed air through-opening to the wheel, and from the wheel into the tire.

Abstract: The invention relates to a subframe for the vehicle chassis of motor vehicles, which subframe has at least one cavity usable as a pressure accumulator and has a cross member (1) which is connected, at the two end faces (27, 28) thereof, to a node element (3, 4). Bearing elements (10 to 12) and/or further frame elements are attached to the node elements (3, 4). The cross member (1) is formed as a continuous rib-reinforced component or extruded part (15) and forms for the pressure accumulator a pressure-resistant cavity which is closed off by the node elements (3, 4) at the end faces.
