Problems solved by technology

[0003] There are at least the following problems in the above-mentioned prior art: the support wheels on the maglev train in the prior art are relatively small, and only play a supporting role; the train adopts magnetic drive when starting, and the magnetic conversion rate is low when the vehicle speed is slow. Low, slow acceleration, so the use of magnetic drive will cause a lot of energy loss, which is not conducive to cost control

Embodiment 1

[0045] The rail transit system 100 according to the present embodiment will be described below with reference to the drawings.

[0046] Such as Figure 1-Figure 2 As shown, the rail transit system 100 according to this embodiment includes a rail vehicle 1 and a rail 2 .

[0047]The rail vehicle 1 includes a bogie 12 and a car body 11, the car body 11 is connected to the bogie 12 and is pulled by the bogie 12 to run along the track 2, the bogie 12 includes a frame 121, The traveling wheel driving device 122 fixedly connected with the frame 121, and the traveling wheel driving device 122 transmission connected, the bogie also includes a magnetic levitation module 127, the magnetic levitation module 127 is installed on the track 2 for providing guidance force, levitation force and driving force for the rail vehicle 1. In summary, the rail transit system 100 combines the magnetic levitation module and the running wheels to realize the dual-mode control of the vehicle on the rail...

Embodiment 2

[0062] This embodiment also provides a rail transit system 100 . Such as Figure 5-Figure 6 As shown, the difference from Embodiment 1 is that the magnetic levitation unit 1272 is disposed on the bottom plate 1263 of the lifting assembly 126 , and the magnetic drive unit 1273 is disposed on the levitation plate 125 .

[0063] When the gap between the magnetic drive unit 1273 and its corresponding magnetic drive component 215 on the track changes, the lifting mechanism 1262 drives the bottom plate 1263 to move up and down, adjusting the magnetic levitation unit 1272 and the magnetic levitation component 214, so as to adjust the levitation force on the bogie 12, and finally adjust the gap between the magnetic drive unit 1273 and the magnetic drive part 215, thereby improving the magnetic force conversion efficiency.

[0064] In some embodiments of the present invention, such as Figure 3-Figure 6 As shown, the magnetic levitation module 127 further includes a magnetic guiding ...

Abstract

The invention provides a rail used for a rail transit system. The rail includes a rail beam and a connection beam; the rail beam includes a first rail beam and a second rail beam, and the first rail beam is provided with a first walking portion for traveling by a rail vehicle of the rail transit system; the first rail beam and the second rail beam are disposed in parallel and at an interval, and the second rail beam is provided with a second walking portion for traveling by the rail vehicle of the rail transit system; and both ends of the connection beam are respectively connected with the first rail beam and the second rail beam, an inner groove is defined between the first rail beam, the second rail beam and the connection beam, a magnetic levitation device is disposed in the inner groove, and the magnetic levitation device is used for driving the rail vehicle of the rail transit system to travel. The rail can be used as the rail for walking wheels of the rail vehicle to travel or can be used as the rail for the magnetic levitation device of the rail vehicle to drive.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a track used in a rail transportation system. Background technique [0002] In the related art, the magnetic levitation bogie on the vehicle is composed of a bogie frame, a magnetic levitation module and supporting wheels. During the running of the vehicle, the magnetic levitation module provides the vehicle with a levitation state, and controls the vehicle to run normally, and when the magnetic levitation module stops working, the supporting wheels contact the reaction rail, which can play a supporting role. [0003] There are at least the following problems in the above-mentioned prior art: the support wheels on the maglev train in the prior art are relatively small, and only play a supporting role; the train adopts magnetic drive when starting, and the magnetic conversion rate is low when the vehicle speed is slow. Low, slow acceleration, so the use of magnetic ...
