Abstract

A cruise control for a vehicle having a throttle controller mounted to a handlebar is provided. The cruise control includes a throttle-pipe handle having a throttle-pipe spur gear attached thereto, a cruise control spur gear coupled to the throttle-pipe spur gear, an electromagnetic brake/clutch device coupled to the cruise control spur gear, an activation switch, and a control circuit. The cruise control spur gear may be coupled to the throttle-pipe spur gear via an intermediate spur gear. The control circuit provides a control signal to activate the electromagnetic brake/clutch device when the activation switch is actuated. When activated, the electromagnetic brake/clutch device prevents rotation of the throttle-pipe handle. When the braking system of the motorcycle is activated, the control signal provided to the electromagnetic brake/clutch device is removed, which deactivates the brake/clutch device, allowing free rotation of the throttle-pipe handle.

Claims

1. A cruise control for a vehicle having an engine and a throttle controller mounted to a handlebar, comprising:

(a) a throttle pipe handle adapted to be coupled to the engine such that a speed of the engine is adjusted by rotation of the throttle pipe handle;

(b) a throttle pipe spur gear attached to the throttle pipe handle such that rotation of the throttle pipe handle rotates the throttle pipe spur gear;

(c) a cruise control spur gear coupled to the throttle pipe spur gear such that rotation of the throttle pipe spur gear rotates the cruise control spur gear; and

(d) an electromagnetic brake/clutch device coupled to the cruise control spur gear.

2. The cruise control of claim 1 wherein the throttle pipe spur gear is an integrally formed part of the throttle pipe handle.

3. The cruise control of claim 1 wherein the cruise control spur gear is coupled to the throttle pipe spur gear by an intermediate spur gear meshed to both the cruise control spur gear and the throttle pipe spur gear such that rotation of the throttle pipe spur gear rotates the intermediate spur gear which in turn rotates the cruise control spur gear.

4. The cruise control of claim 3 wherein a diameter of the throttle pipe spur gear is larger than a diameter of the intermediate spur gear and wherein the diameter of the intermediate spur gear is larger than a diameter of the cruise control spur gear.

5. The cruise control of claim 1 wherein the electromagnetic brake/clutch device is an electromagnetic device selected from the group of electromagnetic devices consisting of an electromagnetic brake/clutch, an electromagnetic spring clutch, and an electric stepper motor.

6. The cruise control of claim 1 wherein the electromagnetic brake/clutch device is coupled to the cruise control spur gear by a cruise control shaft.

7. The cruise control of claim 1 wherein the throttle pipe spur gear and the cruise control spur gear are enclosed in a gear box housing.

8. The cruise control of claim 1 wherein the electromagnetic brake/clutch device is enclosed in an electromagnetic brake/clutch housing.

9. A cruise control for a vehicle having an engine and a throttle controller mounted to a handlebar, comprising:

(a) a throttle pipe handle adapted to be coupled to the engine such that a speed of the engine is adjusted by rotation of the throttle pipe handle;

(b) a throttle pipe spur gear attached to the throttle pipe handle such that rotation of the throttle pipe handle rotates the throttle pipe spur gear;

(c) a cruise control spur gear coupled to the throttle pipe spur gear such that rotation of the throttle pipe spur gear rotates the cruise control spur gear; and

(d) an electric motor coupled to the cruise control spur gear.

10. The cruise control of claim 9 wherein the throttle pipe spur gear is an integrally formed part of the throttle pipe handle.

11. The cruise control of claim 9 wherein the cruise control spur gear is coupled to the throttle pipe spur gear by an intermediate spur gear meshed to both the cruise control spur gear and the throttle pipe spur gear such that rotation of the throttle pipe spur gear rotates the intermediate spur gear which in turn rotates the cruise control spur gear.

12. The cruise control of claim 11 wherein a diameter of the throttle pipe spur gear is larger than a diameter of the intermediate spur gear and wherein the diameter of the intermediate spur gear is larger than a diameter of the cruise control spur gear.

13. The cruise control of claim 9 wherein the electric motor is an electric stepper motor.

14. The cruise control of claim 9 wherein the electric motor is coupled to the cruise control spur gear by a cruise control shaft.

15. The cruise control of claim 9 wherein the throttle pipe spur gear and the cruise control spur gear are enclosed in a gear box housing.
