Abstract
In a transmission having shaft-mounted components operated by a pressurized medium or fluid, the fluid is supplied to the components using an at least partially hollow shaft. A hollow tube within the bore of the shaft carries the fluid. The tube may be divided into separate passageways so as to control flow of fluid to selected components and isolate components from each other. The fluid pressure in the components may be torque-dependently modulated by a torque sensor.
