    Abstract: Disclosed is an embodiment of a turbocharger roller support system that utilizes roller-shaft interfaces that are slanted to locate a turbocharger shaft with a turbine and compressor. Slanted contact surfaces on the turbocharger shaft are slanted inwardly so that the turbo shaft remains centered in the roller support system. The rollers entirely locate the turbocharger shaft, so that no bearings are necessary directly on the turbocharger shaft. The rollers spin at a slower speed than the turbocharger shaft, so can utilize lower speed bearings.

    Abstract: Disclosed is a planetary traction drive for a driven turbocharger that utilizes angular contact ball ramps to provide variable clamping depending on torque throughput. The ball ramps are located between ring rollers and a ring gear, and function to locate the ring gear concentrically to the ring rollers. The angled contact axes of the ball ramps allows use of a low conformity contact between the balls and ball races in the ball ramps to provide efficient movement, while simultaneously locating ring gear concentrically to the traction rings.

    Abstract: Disclosed is a driven turbocharger for an engine with dual stage compressors. In addition to the turbine and compressor on the main turbo shaft of the driven turbocharger, an additional compressor is coupled to a transfer gear of the driven turbocharger to provide two-stage compression for the engine. This enables higher boost pressures, which can help boost engine efficiency. The driven turbocharger retains the single turbine, so that no additional heat sinks are added to the exhaust to keep exhaust temperatures high for aftertreatment functionality.

    Abstract: Disclosed is an adjustable ring shim for a planetary traction drive designed for a driven turbocharger on an engine. The adjustable ring shim has two parts that interface through a ramp feature to provide an ability to vary the overall width of the ring roller assembly of the planetary traction drive. This adjustability in the width of the ring roller allows for setting a desired preload force on the traction surfaces of the traction drive during assembly, even with variation in manufacturing of the different parts of the traction drive.

    Abstract: Disclosed is a turbine bypass for an engine with a driven turbocharger. During engine cold start, or periods of idle or low load engine operation, the bypass can be utilized to direct hot exhaust gasses directly to an exhaust aftertreatment. This provides higher temperatures to the exhaust aftertreatment, increasing the ability to eliminate harmful emissions such as NOx. The driven turbocharger can still provide boost to the engine through supercharging, so that engine torque and power can be maintained while the turbine bypass is in operation.

    TWO-PIECE SUN RACE FOR DRIVEN TURBOCHARGER

    Abstract: Disclosed is a two-piece sun race precision fit onto the turbo shaft of a driven turbocharger with a traction drive that transmits torque to and from the turbo shaft. The turbo shaft is attached to a turbine and compressor and is inserted into a two-piece sun race that has traction surfaces to mate to the traction drive. This allows for simplification in manufacturing and assembly of the traction drive, as the two parts of the sun race can be simplified over a single-piece traction barrel and allow for greater flexibility in the design and assembly of the driven turbocharger than would be possible with a single-piece traction barrel.
