  • Patent number: 10227992
    Abstract: A rotor for a turbocharger device has a shaft and, arranged and fixed axially one behind the other on the shaft, an impeller wheel, a sealing bushing element and an axial bearing element which rotates with the shaft. The sealing bushing element and the axial bearing element, by way of an internal thread provided on at least one of the elements, are screwed to a first external thread arranged on the shaft and are braced against a shaft shoulder. Stronger and more rigid fixing of the parts that are pushed onto the shaft, and thus also lower susceptibility to vibration-induced faults during operation, are achieved by way of this construction.

  • Patent number: 9664063
    Abstract: A turbocharger has an exhaust gas turbine, a fresh-air compressor and a bearing seat. A rotor shaft that is equipped with the turbine and the compressor wheel is rotatably mounted in the bearing seat by way of at least one radial bearing. The radial bearing is a floating bush bearing with a hollow-cylindrical floating bush body positioned between a bearing seat of the bearing housing and the rotor shaft. The floating bush body is provided with a defined imbalance in order to counteract an imbalance of the turbo rotor.

  • Patent number: 9624979
    Abstract: A turbocharger has a turbocharger housing having at least one section divided along a longitudinal axis into at least two housing halves. A bearing block device is provided in the turbocharger housing and receives a shaft and impellers of the turbocharger. The shaft with the impellers can be preassembled in the bearing block device and then inserted into the turbocharger housing.

  • Patent number: 9546569
    Abstract: A turbocharger has a turbine housing and a bearing housing that is connected to the turbine housing. The turbine housing is formed with a coolant inlet, a cooling jacket in the interior of the turbine housing, and a coolant outlet. The bearing housing has a coolant inlet, a cooling jacket in the interior of the bearing housing, and a coolant outlet. The coolant inlet of the bearing housing is connected to a branched coolant outlet of the turbine housing. The coolant outlet of the bearing housing is connected to a coolant return inlet of the turbine housing.

  • Patent number: 9109501
    Abstract: An exhaust-gas turbocharger includes a turbine housing and a wastegate which is disposed in the turbine housing and has a wastegate flap. The wastegate flap can be adjusted by an output shaft of a wastegate actuator. The output shaft has a central axis. The wastegate actuator is an integral constituent part of the turbine housing. During an adjustment of the wastegate flap, the output shaft of the wastegate actuator interacts with a wastegate spindle which has a central axis. The output shaft of the wastegate actuator is thermally decoupled from the wastegate spindle.
