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 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 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: 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.
