Abstract
A supercharger drive system that includes a shaft connected to a set of gears; a one-way clutch provided for connection to the shaft; and an actuation controller in communication with the one-way clutch. In an embodiment, the one-way clutch can disengage and rotors or impellers associated with the system are permitted to rotate independently of the one-way clutch.
Claims21
A two-speed supercharger drive system, comprising:
- an actuation controller;
- an outer shaft connected to the actuation controller and also connected to a step-up gear, the step-up gear provided for connection to a first rotor of the system;
- an inner shaft connected to a one-way clutch, the one-way clutch connected to a second rotor of the system;
- the outer shaft and inner shaft are concentric;
- and
- wherein the one-way clutch is configured for disengagement when the second rotor associated with the system is permitted to rotate independently of the one-way clutch, and the system is driven at a higher rotational speed provided by the step-up gear to the first rotor that is controlled by the actuation controller, and further wherein the one-way clutch is configured for reengagement when the second rotor associated with the system is rotating at substantially the same speed and direction as an input pulley, and wherein reengagement of the one-way clutch is configured to occur at variable speeds of the input pulley.
3 more elements
A two-speed supercharger drive system, comprising:
- an actuation controller;
- an outer shaft connected to the actuation controller and also connected to a gear having a gear ratio greater than 1:1, the gear provided for connection to a first rotor of the system;
- and
- an inner shaft connected to a one-way clutch, the one-way clutch connected to a second rotor of the system;
- the outer shaft and inner shaft are concentric;
- and
- wherein the one-way clutch is configured for disengagement when the second rotor associated with the system is permitted to rotate independently of the one-way clutch, and the system is driven at a higher rotational speed provided by the gear to the first rotor that is controlled by the actuation controller, and further wherein the one-way clutch is configured for reengagement when the second rotor rotors associated with the system is rotating at substantially the same speed and direction as an input pulley, and wherein reengagement of the one-way clutch is configured to occur at variable speeds of the input pulley.

- and
- an inner shaft connected to a one-way clutch, the one way clutch provided for connection to a second rotor of the system;
- the outer shaft and inner shaft are concentric;
- and
- wherein the one-way clutch is configured for disengagement when the second rotor associated with the system is permitted to rotate independently of the one-way clutch and the system is driven at a higher rotational speed provided by the gears to the first rotor that is controlled by the actuation controller, and further wherein the one-way clutch is configured for reengagement when the second rotor associated with the system is rotating at substantially the same speed and direction as an input pulley, and wherein reengagement of the one-way clutch is configured to occur at variable speeds of the input pulley.
