The present invention is a turbocharger unit (10) incorporating variable turbine geometry. The unit (10) has a turbine for receiving exhaust gases from an engine having a turbine wheel (14) located inside a turbine housing (12), and an intermediate housing (24) connected to the turbine housing (12), having a recessed portion (28). A spring member is located in the recessed portion (28), and a heat shield (32) for receives apply force from the spring member. There is also a cartridge (36) for providing variable turbine geometry located between a first disk (34) and a second disk (40) in the turbine housing (12); the second disk (40) is held in contact with the turbine housing (12) by a contoured sleeve (26). The apply force received by the heat shield (32) from the spring member transfers through the first disk (34), the cartridge (36), and the second disk (40), locating the cartridge (36) in proximate relationship to the turbine wheel (14). |
