A flywheel for use in an automobile between an engine and a clutch assembly is provided. The flywheel is a circular member having an engine side and an opposite clutch side. An aperture is formed in the circular member having an axis, and the aperture is used to operatively attach the flywheel to the engine. A plurality of clutch fins and/or grooves are formed on the clutch side adjacent the outer edge of the circular member and spaced radially about the axis of the aperture of the flywheel. The clutch fins have a face that is generally coplanar with the clutch side of the circular member. The fins and grooves work to cool the internal components of the engine. Optionally, a second set of grooves and fins may be formed on the engine side of the flywheel to further aid in cooling the clutch disc and other engine components.

A dual clutch having a flywheel comprising an inner conical surface and an outer conical surface, a first clutch comprising a first contact member that is axially movable along an axis relative to first and second transmission-side input shafts for engaging a first conical clutch disc connected to a first input shaft with the inner conical surface of the flywheel, a second clutch comprising a second contact member that is axially movable along the axis relative to the first and second transmission-side input shafts for engaging a second conical clutch disk connected to a second input shaft with the outer conical surface of the flywheel, a mounting means connected to a clutch housing of the dual clutch or to a transmission housing of a motor vehicle transmission, and, actuation means for moving the first clutch and/or the second clutch along the axis.

An electromechanical flywheel machine includes a multi-wall containment system used in connection with a motor-generator for exchanging energy with a flywheel mass.

A flywheel system including a rotor shaft. The rotor shaft includes an inner passage therethrough, and a dam with a central opening disposed on a first end of the inner passage. An outer passage surrounds the inner passage. The inner passage is open at a second end, and the outer passage is closed on an end surrounding the second end of the inner passage. The outer passage is open on an end surrounding the first end of the inner passage. Fluid flows into the inner passage at the first end, via the central opening of the dam. Rotation of the flywheel rotor causes the fluid to accumulate along a wall of the inner passage, and to propagate to the second end, where the fluid exits into the outer passage. The fluid propagates along the outer passage to the open end of the outer passage, where it is released.

At least one embodiment of the invention relates to an energy storage device comprising a housing, at least one flywheel disposed in the housing, and at least one stabilizing element disposed in the housing configured to stabilize the flywheel. There can be at least one cooling element for cooling a region interior of the housing to a preset temperature. In at least one embodiment, the stabilizing element comprises a magnet. In at least one embodiment the stabilizing element can be orientated at a position offset from a horizontal axis. In at least one embodiment the stabilizing element is orientated at a position offset from a vertical axis In at least one embodiment the stabilizing element is orientated at a position between a horizontal axis and a vertical axis. In at least one embodiment, the stabilizing element comprises at least one magnet coupled to the flywheel orientated at a first angle and at least one magnet coupled to the housing orientated at an angle substantially parallel to said first angle of orientation of the magnet coupled to the flywheel.

This disclosure relates generally to roll stabilization and related apparatuses.
