Abstract: A drum brake with a carrier, a deformation sensor, and at least one brake shoe. The carrier is connected to a supporting bearing for the at least one brake shoe. The deformation sensor is designed to determine a deformation of the carrier. A brake system includes at least one such drum brake, and a vehicle with such a brake system or with at least one such drum brake.

Abstract: The invention relates to a method for introducing a balancing mark into the compressor wheel of a turbocharger. According to the method, a milling tool is firstly moved in a first direction in order to introduce a recess into the compressor wheel, and the milling tool located in the recess then runs out in a second direction in order to convert the recess into a pear segment-shaped balancing mark. The invention furthermore relates to a turbocharger which comprises a compressor wheel that has one or more pear segment-shaped balancing marks.

Abstract: Disclosed is a turbocharger for an internal combustion engine, having a bearing housing. A turbocharger rotor is mounted to be rotatable in the bearing housing about the rotor axis of rotation of its rotor shaft, wherein a turbine wheel is arranged for conjoint rotation on the rotor shaft and in a turbine housing fixed on the bearing housing. Between the rotor shaft and the bearing housing, an oil seal for sealing the bearing housing with respect to the turbine housing is arranged between the turbine wheel and a radial bearing associated with the turbine wheel in order to seal the bearing housing with respect to the turbine housing. A predetermined breaking point is formed for the turbocharger rotor of the turbocharger which lies in a breaking point region and extends axially between the turbine wheel back and an axial end, facing the turbine wheel back, of the rotor-shaft oil seal.

Abstract: A rotor of an exhaust-gas turbocharger includes a rotor hub and rotor blades disposed on the rotor hub. The rotor blades have a blade thickness distribution selected in such a way that the rotor blades have along their extent from a fluid inlet or leading edge to a fluid outlet or trailing edge at least one transition between a stiffness or rigidity-oriented blade thickness distribution and an inertia and stress-oriented blade thickness distribution over the height of the blade.
