Abstract

A maglev system includes a maglev vehicle that reciprocates between a levitated state and a non-levitated state. The vehicle includes a capsule supported by a first left wheel and a corresponding first right wheel when the vehicle is in the non-levitated state. The system further includes a track having a left rail and a right rail, each of the left and right rails having a plurality of plates arranged in series. Proximate ends of adjacent plates define a joint. Each rail provides a support surface that the first left and right wheels rollingly engage when the vehicle is in the non-levitated state. The joints of the left rail are offset in a longitudinal direction from the joints of the right rail.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A maglev system, comprising:
a maglev vehicle that reciprocates between a levitated state and a non-levitated state, the vehicle including a capsule, a first left wheel, and a first right wheel corresponding to the left wheel, the first left and right wheels at least partially supporting the capsule when the vehicle is in the non-levitated state; and
a track comprising a left rail and a right rail, each of the left and right rails having a plurality of plates arranged in seriatim and extending in a longitudinal direction, proximate ends of adjacent plates defining a joint, each rail providing a support surface,
wherein the first left and right wheels rollingly engage the support surface of the left and right rails, respectively, when the vehicle is in the non-levitated state, the joints of the left rail being offset in the longitudinal direction from the joints of the right rail, and the joints of the left rail and the right rail are positioned such that only one of the first left wheel, the first right wheel, the second left wheel, and the second right wheel is in contact with a joint at a given time.

2. The maglev system of claim 1 , wherein the joints of the left rail and the right rail are positioned such that only one of the first left wheel and the first right wheel is in contact with a joint at a given time.

3. The maglev system of claim 1 , wherein the vehicle comprises a bogie mounted to the capsule, the first left and right wheels being rotatably mounted to one end of the bogie, second left and right wheels being rotatably mounted to a second end of the bogie.

4. The maglev system of claim 1 , wherein each plate has a length L, each joint of the left rail being offset from a corresponding joint of the right rail by a distance d, wherein the distance d is a percentage of the length L.

5. The maglev system of claim 4 , wherein the percentage is one of 50%, system 25%, or 10%.

6. A track for a maglev vehicle having a plurality of left wheels and corresponding right wheels that support the vehicle when the vehicle is in a non-levitated state, the track comprising:
a left rail comprising a plurality of left rail plates arranged in seriatim and extending in a longitudinal direction, each end of each left rail plate defining a left joint with an end of an adjacent left rail plate, the left rail defining a left support surface; and
a right rail parallel to the left rail and comprising a plurality of right rail plates arranged in seriatim and extending in the longitudinal direction, each end of each right rail plate defining a right joint with an end of an adjacent right rail plate, the right rail defining a right support surface,
wherein the plurality of left wheels and corresponding right wheels rollingly engage the left and right support surfaces, respectively, when the vehicle is in the non-levitated state, each left joint being offset from a corresponding right joint in the longitudinal direction, and the joints of the left rail and the right rail are positioned such that only one of the plurality of first left wheel, the first right wheel, the second left wheel, and the second right wheel is in contact with a joint at a given time.

7. The track of claim 6 , wherein each left plate and right plate has a length L, each left joint being offset from a corresponding right joint by a distance d, wherein the distance d is a percentage of the length L.

8. The track of claim 7 , wherein the percentage is one of 50%, 25%, or 10%.
