Abstract: An electric machine with a stator, a rotor, and a fluid cooling device. The rotor is supported by a rotor shaft and a first bearing arranged at a bearing shield. The fluid cooling device has a cooling tube secured to a carrier element in fluidic communication with a fluid input and output and extends inside a recess of the rotor shaft while forming an annular space. A sealing element is provided between the rotor shaft and the carrier element, which prevents fluid passage into a spatial region of the electric machine outside of the sealing region. A second bearing is axially spaced apart from the first bearing is between the rotor shaft and a second bearing shield for supporting the rotor. The rotor core extends in a space between the first bearing and second bearing, and the recess extends inside the rotor shaft axially to the second bearing.

Abstract: The invention relates to a disk brake for a utility vehicle, comprising a brake caliper, which extends over a brake disk and which is slidably held on at least one guide bar, which is connected to a stationary brake bracket by means of a screw, wherein the screw is fed through the guide bar, is designed in such a way that the guide bar has impressing elements, which are formed on the end face of the guide bar that lies against the brake bracket, at least in a circumferential and/or radial partial region, which impressing elements engage into the brake bracket in an impressed manner in such a way that an interlocking connection and/or a frictional connection is formed.
