    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 a spring for preload in a planetary traction drive designed for a driven turbocharger on an engine. The ring roller of the planetary traction drive has two parts with a spring between the two parts for generating a preload force on the ring roller assembly of the planetary traction drive. The spring provides a spreading force on the ring roller, and allows for setting a desired preload force on the traction surfaces of the traction drive during assembly and operation, even with variations in manufacturing of the different parts of the traction drive.

    Abstract: Disclosed is a fluid damping system for a planetary traction drive designed for a driven. turbocharger on an engine. The planetary traction drive has a plurality of double roller planets that are each supported by two planet hearings, one at each end of the double roller planet. Each planet bearing has a fluid damping system that consists of a radial squeeze film damper that feeds fluid to an axial squeeze film damper to absorb vibrations and dissipate kinetic energy in the planetary traction drive.

    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.
