Power transmission mechanism for hybrid type fly-wheel device

Claim 2

A power transmission mechanism for a hybrid type fly-wheel vehicle, comprising in combination: (a) a casing; (b) a drive shaft connected to an internal combustion engine, and supported in one part of said casing; (c) at least one fly-wheel rotatably supported on a shaft which is disposed perpendicularly to said drive shaft; (d) a propeller shaft held in said casing in alignment with said drive shaft and which receives driving power from said fly-wheel; (e) a plurality of ring gears formed concentrically and circumferentially on the surface of said fly-wheel; (f) drive gears rotatably supported on the drive shaft; (g) reverse gears and driven gears rotatably supported on said propeller shaft, said driven gears being separated from, and confronting to, said reverse gears with said fly-wheel supporting shaft as a separating point; (h) an electromagnetic clutch mechanism coaxially provided on each of said drive gears, reverse gears, and driven gears, said clutch mechanism functioning to connect and disconnect each said gear in accordance with numbers of revolution of the internal combustion engine; (i) a first control mechanism which disconnects said electromagnetic clutch mechanism, and closes a throttle valve by detecting increase in the numbers of revolution of the internal combustion engine to a predetermined value; and (j) a second control mechanism which opens said throttle valve, and connects said electromagnetic mechanism again by detecting decrease in the numbers of revolution of said fly-wheel to a predetermined value.

Claim 3

The power transmission mechanism as set forth in claim 1, wherein said fly-wheel comprises first and second fly-wheel components, and said second fly-wheel component is provided with an electrically energizing means to connect and disconnect said second fly-wheel component to said first fly-wheel component when said first fly-wheel component reaches its predetermined numbers of revolution.

Claim 4

A power transmission mechanism for a hybrid type fly-wheel vehicle, comprising in combination: (a) a casing; (b) a drive shaft connected to an internal combustion engine, and supported in one part of said casing; (c) at least one fly-wheel rotatably supported on a shaft which is disposed perpendicularly to said drive shaft; (d) a propeller shaft held in said casing in alignment with said drive shaft and which receives driving power from the fly-wheel; (e) a plurality of ring gears formed concentrically and circumferentially on the surface of said fly-wheel; (f) drive gears rotatably supported on said drive shaft; (g) reverse gears and driven gears rotatably supported on said propeller shaft, said driven gears being separated from, and confronting to, said reverse gears with said fly-wheel supporting shaft as a separating point; (h) a first electromagnetic clutch mechanism coaxially provided on each of said drive gears to connect and disconnect each said gear in accordance with numbers of revolution of the internal combustion engine; (i) a first control mechanism to disconnect said first clutch mechanism and close a throttle valve by detecting increase in the numbers of revolution of the internal combustion engine to a predetermined number; (j) a second control mechanism to open said throttle valve and connect said first clutch mechanism again by detecting decrease in the numbers of revolution of said fly-wheel to a predetermined number; (k) a second electromagnetic clutch mechanism coaxially provided on each of said reverse gear and driven gears to connect and disconnect each said gear in accordance with speed increasing and decreasing operations of an accelerator operating section; and (l) a third control mechanism which disables function of said accelerator operating section in association with stopping operating of a brake operating section to release said second electromagnetic clutch mechanism.

Claim 5

A power transmission mechanism for a hybrid type fly-wheel vehicle, comprising in combination: (a) a casing; (b) a drive shaft connected to an internal combustion engine, and supported in one part of said casing; (c) at least one fly-wheel rotatably supported on a shaft which is disposed perpendicularly to said drive shaft; (d) a propeller shaft held in said casing in alignment with said drive shaft and which receives driving power from the fly-wheel; (e) a plurality of ring gears formed concentrically and circumferentially on the surface of said fly-wheel; (f) drive gears rotatably supported on said drive shaft; (g) reverse gears and driven gears rotatably supported on said propeller shaft, said driven gears being separated from, and confronting to, said reverse gears with said fly-wheel supporting shaft as a separating point; (h) a first electromagnetic clutch mechanism coaxially provided on each of said drive gears to connect and disconnect each said gear in accordance with numbers of revolution of the internal combustion engine; (i) a first control mechanism to disconnect said first clutch mechanism and close a throttle valve by detecting increase in the numbers of revolution of the internal combustion engine to a predetermined number; (j) a second control mechanism to open said throttle valve and connect said first clutch mechanism again by detecting decrease in the numbers of revolution of said fly-wheel to a predetermined number; (k) a second electromagnetic clutch mechanism coaxially provided on each of said reverse gear and driven gears to connect and disconnect each said gear in accordance with speed increasing and decreasing operations of an accelerator operating section; and (l) a third control mechanism which disables function of said accelerator operating section in association with stopping operating of a brake operating section to release said second electromagnetic clutch mechanism.

Claim 6

The power transmission mechanism as set forth in claim 3, wherein said fly-wheel comprises first and second fly-wheel components, and said second fly-wheel component is provided with an electrically energizing means to connect and disconnect said second fly-wheel to said first fly-wheel when said first fly-wheel component reaches its predetermined numbers of revolution.
