Abstract: A compressor wheel for a compressor of a turbocharger has a hub and a multiplicity of blades on the hub. In intermediate spaces of the multiplicity of blades, a channel is in each case formed between a suction side and a pressure side. The channel guides fluid that flows in axially in relation to a rotation axis radially or radially-axially outward. The hub in relation to the rotation axis is contoured such that the hub has a rotationally symmetrical portion and a non-rotationally symmetrical portion. On the non-rotationally symmetrical portion, a transition between the hub and each of the blades is embodied with a radiused connection and facing the suction side has a region of modified thickness. A region formed by control rays is generated in at least one channel between the suction side and the pressure side on the hub. A method produces the compressor wheel.

Abstract: A method for compensating sensor tolerances of accelerometers of a vehicle. The method includes following steps: recording of measurement signals of at least three similarly oriented accelerometers, calculation of an acceleration (ab,z) at a reference position in the spatial direction, which corresponds to the orientation of the accelerometers, low-pass filtering of the measurement signals, determination of tolerance parameters (cx, cy, cz) of each sensor via an optimization method with the aid of the calculated acceleration (ab,z) at the reference position, and calculation of the adjusted measurement signals from the recorded measurement signals and the tolerance parameters (cx, cy, cz).

Abstract: A compressor wheel for a compressor of a turbocharger has a hub (16) and a multiplicity of blades (12) on the hub (16). In intermediate spaces of the multiplicity of blades (12), a channel is in each case formed between a suction side (24) and a pressure side (26). The channel guides fluid that flows in axially in relation to a rotation axis (22) radially or radially-axially outward. The hub (16) in relation to the rotation axis (22) in at least one channel is contoured with a rotationally symmetrical portion (18?) and a non-rotationally symmetrical portion (18). The non-rotationally symmetrical portion (18) is formed by radii that are variable in the flow direction, and a transition region (28) between the hub (16) and the blade (12) adjoins the non-rotationally symmetrical portion (18).

Abstract: A damping module for two damping devices on two wheel carriers of an axle of a vehicle, having a first damping circuit with a first upper damping connection to an upper damping chamber of a first damping device and a first lower damping connection to a lower damping chamber of the first damping device. A first pump device is arranged in a first pumping connection between the first upper damping connection and the first lower damping connection. Two valve combinations are oriented in opposite directions and include, in each case, a nonreturn valve (RV) and an adjustable throttle valve (DV) arranged in a first compensating connection. A second damping circuit with a second upper damping connection to an upper damping chamber of a second damping device and a second lower damping connection to a lower damping chamber of the second damping device are provided.
