Devices and methods for connecting a spoke to a hub
A spoke for a wheel can include a first end, a second end, and an attachment section therebetween, the first end and the second end extend at an acute angle with respect to each other, the attachment section including a non-circular portion in cross-section.
1. A spoke for a wheel, comprising:
a first end, a second end, and an attachment section therebetween, the first end and the second end extend at an acute angle with respect to each other, the attachment section including a non-circular portion in cross-section shaped to be captured beneath and secured by an overhang of an attachment pocket formed on an exterior side surface on the wheel, wherein the non-circular portion is receivable within the attachment pocket along a first direction, and is locked within the attachment pocket in response to a movement of the spoke different than the first direction.
2. The spoke as recited in claim 1 , wherein the non-circular portion includes a flat section.
3. The spoke as recited in claim 1 , wherein the non-circular portion includes a triangular section.
4. The spoke as recited in claim 1 , wherein the non-circular portion includes a wedge section.
5. The spoke as recited in claim 1 , wherein the non-circular portion includes a flat section that defines a plane that does not contain the first end and the second end.
6. The spoke as recited in claim 1 , wherein the acute angle of the spoke is between 20 degrees and 60 degrees.
7. The spoke as recited in claim 1 , wherein the acute angle of the spoke is 40 degrees.
8. A wheel, comprising:
a wheel rim;
a wheel hub having a first and second side; and
a plurality of wheel spokes connecting the wheel rim to the wheel hub, each of the plurality of wheel spokes has a first end, a second end, and an attachment section therebetween including a non-circular portion in cross-section, the first end and the second end extend at an acute angle with respect to each other and attach to the wheel rim, the attachment section attached to an attachment pocket in the wheel hub such that the attachment section is captured beneath and secured by an overhang of the attachment pocket due to the non-circular portion, wherein, for each wheel spoke, the non-circular portion is receivable within the attachment pocket along a first direction, and is locked within the attachment pocket in response to a movement of the wheel spoke different than the first direction.
9. The wheel as recited in claim 8 , wherein the movement of the wheel spoke different than the first direction includes a second direction different than the first direction.
10. The wheel as recited in claim 8 , wherein the movement of the wheel spoke different than the first direction includes a rotation.
11. The wheel as recited in claim 8 , wherein each attachment pocket is shaped to retain and secure the attachment section of a wheel spoke.
12. The wheel as recited in claim 11 , wherein the attachment pocket has a shape that is one of: a curved shape and an angled shape.
13. The wheel as recited in claim 8 , wherein the acute angle of the plurality of wheel spokes ranges between 20 degrees and 60 degrees.
14. The wheel as recited in claim 8 , wherein the acute angle of the plurality of wheel spokes is 40 degrees.
15. The wheel as recited in claim 8 , wherein the wheel is an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle.
16. A method of assembling a spoke wheel comprising:
inserting an attachment section of a wheel spoke into an attachment pocket in a wheel hub via an aperture of the attachment pocket, the wheel spoke including a first end, a second end, and the attachment section therebetween, wherein the attachment section includes a non-circular portion in cross-section and the first end and the second end extend at an acute angle with respect to each other; and
rotating the wheel spoke such that a widest cross section of the non-circular portion of the wheel spoke is wider than the aperture of the attachment pocket to lock the attachment section into the attachment pocket.
17. The method of claim 16 , further comprising securing the first end and the second end of the wheel spoke to a rim.
18. A spoke for a wheel, comprising:
a first end, a second end, and an attachment section therebetween, the first end and the second end extend at an acute angle with respect to each other, the attachment section including a non-circular portion in cross-section shaped to be captured beneath and secured by an overhang of an attachment pocket formed on an exterior side surface on the wheel, wherein the non-circular portion is receivable within the attachment pocket in a first position, and is locked within the attachment pocket in response to a movement of the spoke to a position different than the first position.
19. A wheel, comprising:
a wheel rim;
a wheel hub having a first and second side; and
a plurality of wheel spokes connecting the wheel rim to the wheel hub, each of the plurality of wheel spokes has a first end, a second end, and an attachment section therebetween including a non-circular portion in cross-section, the first end and the second end extend at an acute angle with respect to each other and attach to the wheel rim, the attachment section attached to an attachment pocket in the wheel hub such that the attachment section is captured beneath and secured by an overhang of the attachment pocket due to the non-circular portion, wherein, for each wheel spoke, the non-circular portion is receivable within the attachment pocket in a first position, and is locked within the attachment pocket in response to a movement of the wheel spoke to a position different than the first position.
