Definitions

  • the present invention generally relates to the field of turbochargers having variable turbine inlet geometries according to claim 1.
  • the present invention more particularly provides a structural arrangement for a variable inlet blade support independent of the turbine housing.
  • turbochargers have significantly increased the overall efficiency and capabilities of turbochargers
  • complexity of support and actuation structures for the blades has increased manufacturing costs and occasionally created maintenance issues.
  • connection of the blade support structure to the turbine housing limits the design and structure flexibility of the turbine housing.
  • Turbine casings are a sensitive thermal load that can affect the performance of emission systems in automotive applications.
  • integration of turbine casings in the exhaust manifold can produce a reduction in the number of parts and the complexity for an automotive turbocharger installation. It is therefore desirable to provide variable nozzle structural support arrangements independent of the turbine housing to improve actuation systems to increase reliability and lower manufacturing costs for the turbochargers that use them.
  • the object of the present invention is the provision of a turbocharger comprising an improved reliability actuation system. This object is achieved by a turbocharger having a combination of the features of claim 1.
  • a variable geometry turbocharger utilizing the present invention includes a central housing having a central bore for carrying a shaft-bearing bearing assembly with a turbine wheel mounted at a first end and a compressor turbine mounted at a second end.
  • a compressor casing incorporating the turbine is attached to the central casing and has an air inlet and a compressed air outlet.
  • a cartridge having a base and an insert is attached to the central housing opposite the compressor housing.
  • the cartridge has a base and an insert.
  • the base and the insertion piece mutually form an exhaust inlet nozzle and the nozzle has an exhaust outlet with an aerodynamic contour corresponding to the turbine wheel.
  • a plurality of blades having rotation posts extending from a first surface substantially parallel to the inner wall of the nozzle constitute the variable nozzle.
  • the posts are received in circumferentially spaced openings in the base of the inner wall of the nozzle.
  • the posts have actuating arms extending to engage in notches in a unison ring engaged between the central housing and the base.
  • the operation of the ring in unison is effected by a crank comprising an actuating arm engaging in a slot in the ring in unison.
  • the crank is continuously movable from a first position to a second position, causing the actuating arm to move in the radial slot and imparting a force perpendicular to the radial slot to drive the rotational movement of the ring to the unison.
  • the rotation movement of the ring in unison causes the blades to rotate by the blade arms.
  • a sheet metal exhaust casing is mounted on the cartridge on the central casing, providing an inlet for the exhaust gas into the nozzle.
  • FIG. figure 1 the embodiment of the invention shown in FIG. figure 1 comprises a compressor housing 10 which is connected to a rear plate 12 using two clamps 14 or more fastened by bolts 16.
  • the back plate is fixed to a central housing 18 with several bolts 20 and an annular seal 22.
  • the sheet metal exhaust casing 24 is connected to the central casing using strips 26 fixed by bolts 28.
  • the exhaust gas or other high-energy gas supplying the turbocharger enter the exhaust casing through the entrance 32.
  • a cartridge generally designated 34, is mounted on the central casing.
  • a turbine wheel and shaft assembly 30 is carried by the bearing, the turbine wheel being suspended within the cartridge.
  • Multiple vanes 36 are mounted on a cartridge base 38.
  • the vanes pivot on posts 40 extending from the vanes into holes 42 in a surface 43 of the base which constitutes the inner wall of the inlet nozzle.
  • Actuating arms 44 extend from the blade posts to engage in notches 46 in the unison ring 48.
  • An actuating crank 50 terminates at a first end by a lever arm 52 carrying a pin 54 for engaging with the slot 56 in the ring in unison for rotation of the ring.
  • the crank extends from a boss 58 in the central housing through a sleeve 60 terminating on an outer arm 62 for engagement by an actuating device.
  • An insertion piece 64 is fixed to the central casing by bolts 66 received in holes 68.
  • Support posts 70 hold the base, pressing the base against spacing pins 39 (best seen on the figure 1 ) received in the central housing.
  • An edge 71 which extends around the circumference of the insertion piece is also engaged by the V-band clamp.
  • the insertion piece has the outer wall of the nozzle 72 in the immediate vicinity of the blades.
  • the insertion piece constitutes the exhaust gas outlet of the turbine 73 with an aerodynamic contour fixing the blades on the wheel of the turbine.
  • the insertion piece and the base with the vanes attached and the actuating elements constitute the cartridge, which is separated from both the central casing and the exhaust casing and fixed between these two components.
  • the use of the cartridge of the present invention makes it possible to simplify the exhaust casing with respect to the prior art designs, facilitating improvements such as a sheet metal exhaust casing, as shown in the embodiments of the invention. drawings.
  • a bearing system having two bearings 74 and a bearing spacer 76 or, in other embodiments, a unit bearing, supports mounting of the shaft wheel in the central bore of the central housing 78.
  • the shaft further extends through a bearing ring 80 which engages with a bearing bearing 82 carried between the central housing and the rear plate of the compressor.
  • a piston ring 84 seals the bearing ring with the shaft bore in the back plate.
  • the compressor turbine 86 is attached to the shaft wheel assembly.
