a housing;
at least one bearing sleeve mounted in the housing; and
at least one mass sleeve mounted within the bearing sleeve, the mass sleeve having a first mass and a second mass coupled thereto, the first mass being larger than the second mass and being positioned substantially 180 degrees from the second mass, wherein
the first mass is coupled to a mass shaft, and
the mass shaft is slidably coupled to an eccentric drive shaft.
2. A device according to claim 1 , wherein the housing is disposed on a rail vehicle.
3. A device according to claim 2 , wherein the rail vehicle is a drone vehicle.
4. A device according to claim 1 , wherein the first and second masses extend along a longitudinal length of the mass sleeve.
5. A device according to claim 1 , wherein the at least one mass sleeve comprises four mass sleeves.
6. A device for generating vertical force, comprising:
a housing;
at least one bearing sleeve mounted in the housing; and
at least one mass sleeve mounted within the bearing sleeve, the mass sleeve having a first mass and a second mass coupled thereto, the first mass being larger than the second mass and being positioned substantially 180 degrees from the second mass, wherein
the first mass is coupled to a mass shaft, and
the first mass includes a pair of slots formed therein.
7. A device according to claim 6 , wherein the housing is disposed on a rail vehicle.
8. A device according to claim 7 , wherein the rail vehicle is a drone vehicle.
9. A device according to claim 6 , wherein the first and second masses extend along a longitudinal length of the mass sleeve.
10. A device according to claim 6 , wherein the at least one mass sleeve comprises four mass sleeves.
11. A method for generating downward forces, comprising:
providing a device having first and second mass sleeves mounted within a housing and a coupled to a drive shaft, wherein each mass sleeve comprises a first mass and a second mass coupled thereto;
rotating the drive shaft to effect rotation of the mass sleeves such that the first and second masses increase in rotational speed as they rotate away from a drive shaft and decrease in rotational speed as they rotate towards the drive shaft, wherein
the first mass sleeve is coupled to the drive shaft via a pair of shafts, and further wherein rotating the drive shaft causes translation of the shafts through the drive shaft.
12. A method according to claim 11 , further comprising rotating the mass sleeves in opposite directions and in such a way that the first masses are in a downward position at substantially the same time.
13. A method according to claim 12 , further comprising rotating the mass sleeves to cancel lateral forces generated by rotation of the mass sleeves.
14. A method according to claim 11 , wherein the pair of shafts are coupled to the first mass and are adapted to pivot relative to the first mass during rotation.
15. A drone rail vehicle, comprising:
a frame;
a track stabilization unit coupled to the frame, the track stabilization unit having a device for generating vertical force comprising:
at least one bearing sleeve mounted in the housing; and
at least one mass sleeve mounted within the bearing sleeve, the mass sleeve having a first mass and a second mass coupled thereto, the first mass being larger than the second mass and being positioned substantially 180 degrees from the second mass, wherein
the first mass is coupled to a mass shaft, and
the mass shaft is slidably coupled to an eccentric drive shaft.
16. A drone rail vehicle according to claim 15 , wherein the first and second masses extend along a longitudinal length of the mass sleeve.
17. A drone rail vehicle according to claim 15 , wherein the at least one mass sleeve comprises four mass sleeves.
18. A drone rail vehicle, comprising:
a frame;
a track stabilization unit coupled to the frame, the track stabilization unit having a device for generating vertical force comprising:
at least one bearing sleeve mounted in the housing; and
at least one mass sleeve mounted within the bearing sleeve, the mass sleeve having a first mass and a second mass coupled thereto, the first mass being larger than the second mass and being positioned substantially 180 degrees from the second mass, wherein
the first mass includes a pair of slots formed therein.
19. A drone rail vehicle according to claim 18 , wherein the first mass is coupled to a mass shaft.
20. A drone rail vehicle according to claim 18 , wherein the first and second masses extend along a longitudinal length of the mass sleeve.
21. A drone rail vehicle according to claim 18 , wherein the at least one mass sleeve comprises four mass sleeves.
22. A method for varying the ratio of an upward and downward, comprising:
providing a device for generating vertical force, the device having:
at least one bearing sleeve mounted in a housing;
at least one mass sleeve mounted within the bearing sleeve, the mass sleeve having a first mass and a second mass coupled thereto, the first mass being larger than the second mass and being positioned substantially 180 degrees from the second mass; and
a gear box disposed adjacent to the mass sleeve; and
varying an offset between a centerline of the gear box and a centerline of the mass sleeve.
