Abstract: Disclosed is a high-speed section disconnect for a driven turbocharger with a traction drive. The turbo shaft is attached to a turbine and compressor, and interfaces with a high-speed traction drive. A mechanical coupling connects the traction drive to a transmission, which is connected to the engine so that power can flow to or from the turbo shaft, but the mechanical coupling can be selectively disconnected so that the high-speed section of the driven turbocharger can also be decoupled from the engine during certain operating conditions to reduce mechanical losses in the system.

Abstract: Disclosed are embodiments of thrust absorbing planetary traction drives that utilize roller-shaft traction interfaces that are slanted to absorb thrust created on a turbo shaft by a turbine or compressor. Slanted traction surfaces on the sun portion of the turbo shaft are slanted inwardly so that the turbo shaft remains centered in the planetary traction drive. Either double roller planets or single roller planets can be used to absorb thrust in the axial direction of the turbo shaft. Various curved and slanted surfaces can be utilized to create traction interfaces that hold and stabilize the turbo shaft both axially and radially.

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 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.

Abstract: Disclosed is an embodiment of a dual seal arrangement for the high-speed shaft of a supercharger with a centrifugal compressor and a mechanical speed step-down transmission to the shaft. A ring located about the shaft splits the rotational speed of the shaft between two seals, so that each seal spins at a speed of roughly half the speed of the shaft. The arrangement can also be used to split the shaft speed between two bearings in the same manner. The high-speed shaft may also have a turbine attached, to form a driven turbocharger.

Abstract: A planetary traction drive for a driven turbocharger 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. A variation is shown where only a single angular contact ball ramp is used between the ring gear and a clamping traction ring, and the other traction ring is rigidly fixed to the ring gear to reduce part count and complexity.

Abstract: Disclosed is a two-piece shaft assembly for a driven turbocharger with a traction drive. The turbo shaft is attached to a turbine and compressor, and is inserted into a traction barrel that has traction surfaces to mate to the traction drive. In this way, the traction drive can be assembled with only the traction barrel, and the turbo shaft can be inserted through the barrel at the end to simplify assembly.

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.
