  • Patent number: 10808569
    Abstract: An exhaust gas turbocharger has a turbine with a turbine wheel. The turbine wheel is axially mounted in a turbine housing and has turbine blades, each with a leading edge for a flow of media. An adjustable guide grate with a plurality of stator vanes adjusts a flow cross-section relative to the leading edge of the turbine wheel. Each stator vane has a vane rear edge facing the turbine wheel. A plane is defined by a rotational axis of the turbine wheel and at least one point on the leading edge, wherein a projection of the leading edge onto the plane is axially inclined relative to the rotational axis of the turbine wheel at least in one region, and the stator vanes are arranged radially about the turbine wheel at least in the region.

  • 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: 9140134
    Abstract: A guide vane of a turbo-compressor has variable turbine geometry, in particular for a motor vehicle. The guide vane has a profile with a lower side, an upper side and a front edge. The guide vane is characterized by a nose which extends along the front edge of the vane, from the front edge of the vane to the upper side of the vane and forms a low pressure on the upper side of the vane when waste gas impacts the guide vane. A guide vane configuration, a turbo-compressor, a motor vehicle and a method for operating this type of turbo-compressor are further disclosed.

  • Patent number: 8932008
    Abstract: A securing element includes a head section and a shank. The cross-section of the shank changes in the axial direction in such a way that, by taking into account a qualitative and/or quantitative predetermined bending torque profile in the shank, the cross-section has a substantially uniform bending stress profile in the shank in relation to a securing element with a constant shank cross-section. An exhaust gas turbocharger having variable turbine geometry includes a VTG-guide vane configuration having at least one such securing element and being secured to a housing component of the exhaust gas turbocharger.
