Patent number: 11333040Abstract: A turbocharger device for an internal combustion engine and a method for mounting a turbocharger device are described. The turbocharger device has a housing with a locating hole, in which a turbocharger shaft is mounted by two rolling element bearings. A rolling element bearing sleeve is situated between the two rolling element bearings. The rolling element bearing sleeve and hence the two rolling element bearings are fixed with the turbocharger shaft in the axial direction with the aid of two pins, which are introduced through a hole in the housing and are pressed into a groove in the rolling element bearing sleeve. During this process, the beveled tips of the pins slide along the chamfered outer edges of the groove as far as an end position, which fixes the axial position of the rolling element bearing sleeve.Type: GrantFiled: April 9, 2020Date of Patent: May 17, 2022Assignee: Vitesco Technologies GmbHInventors: Sasa Slavic, Bernhardt Lüddecke, Bruno Ferling, Dirk Frankenstein, Shuo Li, Jürgen Schindlatz

Patent number: 11060453Abstract: 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.Type: GrantFiled: October 25, 2019Date of Patent: July 13, 2021Assignee: Vitesco Technologies GmbHInventors: Ralf Böning, Michael Klaus, Dirk Frankenstein, Bernhard Lehmayr, Bruno Ferling

Patent number: 10001054Abstract: A method and a device for orienting an actuator of an exhaust-gas turbocharger which has an actuator that is equipped with an actuator housing and is connected to a control rod. First, an actuator holder is fastened to the compressor housing of the exhaust-gas turbocharger. Then the actuator is inserted into the actuator holder. Then the actuator is positioned within the actuator holder. Then a compensating material is introduced through an injection opening into a compensating-material receiving space which is provided in the actuator holder. Finally, the compensating material is hardened.Type: GrantFiled: March 27, 2013Date of Patent: June 19, 2018Assignee: Continental Automotive GmbHInventors: Ralf Boening, Simon Baensch, Bruno Ferling, Dirk Frankenstein

Patent number: 9618038Abstract: A method adjusts axial play of a journal mounted in a bearing. A bearing axis defines a z-direction. A positive z-direction points from first to second bearing ends. The journal inserted into the bearing in the positive z-direction is moved to a first form-locking engagement in the positive z-direction between journal and bearing. A spacer at the second end defines axial play. A bushing is placed onto a journal segment protruding from the bearing at the second end in the positive z-direction. A form-locking and/or force-locking connection is established between bushing and journal by deforming the bushing and locating the spacer along the z-direction between bushing and second end. The spacer contacts the bushing and second end. The spacer is removed. A device having a bearing and a journal mounted and relatively movable therein within axial play is also provided.Type: GrantFiled: January 14, 2014Date of Patent: April 11, 2017Assignee: Continental Automotive GmbHInventors: Uemit Dilalan, Bruno Ferling, Alexander Jaegle

Publication number: 20170082140Abstract: A method produces a mechanical device, in particular an exhaust gas turbocharger. The turbo charger contains an open-loop or closed-loop control device and a mechanical transmission element which is connected directly or indirectly to an actuator on one side and to an adjusting element on the other side, for transmitting a manipulated variable. The transmission element can be deformed prior to the connection to the actuator and the adjusting element and can be adapted in its deformable state to the other components of the device. After the adaptation, the transmission element is fixed by reducing the deformability thereof. The transmission element can be stiffened after the assembly and adaptation. The compensation of tolerances is made possible in this way with particularly low effort.Type: ApplicationFiled: February 19, 2015Publication date: March 23, 2017Inventors: DIRK FRANKENSTEIN, BRUNO FERLING, JOCHEN HELD
