Abstract

A throttle control for a motorcycle comprises an electromagnet mounted adjacent to a throttle tube on a handle bar of the motorcycle. The throttle tube includes a radial flange on one end that is configured to define at least one slot. An armature plate is positioned between the electromagnet and the radial flange and is configured to define at least one tab that registers with the slot in the radial flange of the throttle tube. The armature plate is moveable between a first position in contact with the electromagnet and a second position spaced from the electromagnet while the tab remains within the slot. When the electromagnet is energized, the armature plate frictionally contacts the electromagnet and fixes the radial position of the throttle tube.

Claims

1. A motorcycle throttle control for a motorcycle having a handlebar and a throttle tube rotationally supported on the handlebar, the throttle tube having a circumferential flange, the throttle control comprising:

an electromagnet connected to a handlebar of a motorcycle adjacent to the circumferential flange of the throttle tube;

a metal plate positioned between the electromagnet and the circumferential flange, the metal plate moveable between a first position in contact with the electromagnet and a second position spaced from the electromagnet, the metal plate having at least one tab extending from a surface of the metal plate in a direction toward the circumferential flange;

wherein the circumferential flange is configured-to define at least one slot, the tab of the metal plate extending within the slot when the metal plate is in the first position; and

means for energizing the electromagnet, whereby the metal plate frictionally contacts the electromagnet when the electromagnet is energized to maintain a rotational position of the throttle tube.

2. The motorcycle throttle control of claim 1 wherein electromagnet comprises a ferrous metal housing and a coil positioned within the housing, the housing defining a surface oriented in a plane generally parallel with the circumferential flange, wherein the metal plate contacts the surface of the housing when the metal plate is in the first position.

3. The motorcycle throttle control of claim 2 wherein the housing comprises a generally cylindrical housing having an inner cylindrical surface configured to position the housing over the handlebar, wherein the surface comprises a radial surface.

4. The motorcycle throttle control of claim 2 wherein the housing comprises a circumferential space, the coil positioned within the circumferential space.

5. The motorcycle throttle control of claim 2 wherein the coil is integrally formed with the housing.

6. The motorcycle throttle control of claim 2 and further comprising a clamp secured to the motorcycle handlebar spaced from the housing and an arm having a first end and a second end, the first end connected to the clamp, the second end of the arm connected to the housing.

7. The motorcycle throttle control of claim 1 wherein the metal plate comprises a circular metal plate having an inner circular edge and an outer circular edge, the inner circular edge having a diameter larger than a diameter of the handlebar.

8. The motorcycle throttle control of claim 7 wherein the metal plate comprises a plurality of radially spaced tabs and wherein the circumferential flange is configured to define a plurality of radially spaced slots, the plurality of tabs communicating with the plurality of slots.

9. A motorcycle throttle control for a motorcycle having a handlebar and a throttle tube rotationally supported on the handlebar, the throttle tube having a circumferential flange, the throttle control comprising:

means connected to a handlebar of a motorcycle adjacent to the circumferential flange of the throttle tube for generating an electromagnetic field;

means for reversibly coupling the circumferential flange to the electromagnetic generating means to maintain a rotational position of the throttle tube.
