In some embodiments, as shown in fig. 1 in conjunction with fig. 2, the magnetic levitation mount 20 includes a connecting arm 22 and a side sill 23. The connecting arms 22 are connected with the framework body 10 and extend downwards, the lower longitudinal beams 23 extend in the front-back direction and are connected with the lower ends of the two connecting arms 22, wherein the magnetic suspension mounting part 20 comprises one or a plurality of magnetic suspension modules arranged at intervals in the front-back direction, and the lower longitudinal beams 23 are used for mounting the first magnetic suspension module 21. In other words, the magnetic levitation mounts 20 may be one, two or more, the magnetic levitation mount 20 includes a lower longitudinal beam 23, the first magnetic levitation module 21 is mounted on the lower longitudinal beam 23, that is, the magnetic levitation mount 20 will be subjected to suction or repulsion, wherein the connecting arm 22 plays a role of connecting the lower longitudinal beam 23 and the framework body 10, while the connecting arm 22 is also a main force bearing member.
In some embodiments, there are two connecting arms 22, two connecting arms 22 are symmetrically arranged in the front-rear direction with respect to the mounting opening of the running wheel 201, the upper ends of two connecting arms 22 are connected to the frame body, and the lower ends of the other connecting arm are connected to the two ends of the lower longitudinal beam respectively.

In addition, the bogie frame of the present invention may be an integrated structure, that is, the frame body, the magnetic levitation mounting portion, the driving member mounting portion, and the like may be integrally formed by casting, welding, or the like.
The bogie 200 of the railway vehicle according to the embodiment of the present invention, as shown in fig. 1 in conjunction with fig. 3, includes a bogie frame 100, running wheels 201, running wheel drives (not shown), a first magnetic levitation module 21, and stabilizing wheels 202. The bogie frame 100 is the bogie frame 100 of the railway vehicle.
According to the bogie 200 of the railway vehicle provided by the embodiment of the invention, the running wheels 201, the running wheel driving piece and the first magnetic suspension module 21 are arranged, the railway vehicle is driven to run by driving the running wheels 201, and the running wheels 201 and the magnetic drive jointly act, so that the driving form can be freely switched according to the vehicle speed, the acceleration is improved, and the energy loss is reduced.
Specifically, as shown in fig. 1 and 3, the running wheels 201 are rotatably provided in the running wheel attachment opening 11, the axis of the running wheels 201 extends in the left-right direction, and the lower ends of the running wheels 201 protrude downward out of the running wheel attachment opening 11. The running wheel driving part is installed on the driving part installing part 30, and the running wheel driving part is connected with the running wheels 201 and is used for driving the running wheels 201 to rotate so as to drive the rail vehicle to advance along the front and back direction. The first magnetic levitation module 21 is mounted on the magnetic levitation mounting part 20, and the first magnetic levitation module 21 is used to levitate the rail vehicle. The stabilizing wheels 202 are connected to the stabilizing wheel mounting portion 40, and the axes of the stabilizing wheels 202 extend in the up-down direction.
The running wheels 201 play a supporting role when the vehicle is at rest and runs at a low speed, and the running wheel driving pieces drive the running wheels 201 to rotate so as to drive the vehicle-track vehicle to move. The magnetic driving component and the traveling wheel driving component are arranged relatively independently, for example, the traveling wheel driving component can be operated, and the magnetic driving component is not operated; the magnetic driving part can also be operated, the walking wheel driving part does not operate, or the walking wheel driving part and the magnetic driving part operate simultaneously.
It can be understood that, the rail vehicle is accelerated from a standstill, and the rail vehicle is "levitated" and driven to move in an accelerated manner by means of magnetic force alone, so that the efficiency is low and the energy consumption is high. At this time, it is preferable that the running wheel driving member drives the running wheels 201 to move, and the running wheels 201 drive the whole rail vehicle to move in an accelerated manner. Because the running wheels 201 drive the running wheels 201 to accelerate quickly and run stably, the vehicle can reach a preset speed (for example, 120 kilometers per hour) quickly, and the energy conversion rate is high, so that the energy can be saved and the cost can be controlled. Further preferably, the vehicle may be operated by both magnetic and road wheel drives to accelerate from a standstill, allowing the rail vehicle to have greater acceleration and allow the rail vehicle to reach the destination faster.
When the vehicle reaches a preset speed (for example, 120 kilometers per hour), the energy efficiency of the vehicle is influenced by continuously adopting the running wheel driving, so that the rail vehicle can be suspended when the vehicle runs at a high speed, at the moment, the running wheels 201 are emptied, the rail vehicle cannot be driven to continuously run, the running wheel driving parts can be closed, the resistance of the vehicle during running is small, the magnetic driving parts are opened, the rail vehicle is driven to move along the front-back direction by the magnetic driving parts, the running is stable, the noise is low, the energy conversion rate is high at the moment, and the energy can be further saved.
In addition, when the speed of the vehicle is low, the running wheels 201 drive the vehicle to run, and when the rail vehicle needs to turn, the guiding and stabilizing are realized by the stabilizing wheels 202 arranged on the stabilizing wheel mounting parts 40, and in this case, a smaller turning radius can be allowed. Moreover, at low speed, the running of the vehicle driven by the running wheels 201 is more stable than the running of the vehicle driven by electromagnetism.
In some embodiments, the magnetic levitation mount 20 has a shape of a bracket extending in an up-down direction, and the first magnetic levitation module 21 is mounted to a lower end portion of the magnetic levitation mount 20.

In some alternative embodiments, as shown in fig. 1 and 2, the upper surface of the lower longitudinal beam 23 is used for mounting the first magnetic levitation module 21. It will be appreciated that in order to achieve levitation of the railway vehicle, the first magnetic levitation module 21 will impart an upward force to the frame body 10, and the first magnetic levitation module 21 is mounted on the upper surface of the lower side member 23 to transmit an upward component of the attractive force to the connecting arm 22, and the connecting arm 22 moves the frame upward to place the vehicle in a levitated state, and the forward or backward component of the force is used to propel or brake the railway vehicle.

When the rail vehicle needs to turn, the stabilizing wheels 202 are in contact with the rail beam 300, and guiding and stabilizing are achieved by the stabilizing wheels 202 mounted on the stabilizing wheel mounting parts 40, in which case a smaller turning radius may be allowed. Moreover, at low speed, the running of the vehicle driven by the running wheels 201 is more stable than the running of the vehicle driven by electromagnetism.
A railway vehicle (not shown in the figures) according to an embodiment of the invention comprises a car body and the aforementioned bogie 200 of the railway vehicle, wherein the car body is connected with the bogie and the car body is adapted to be pulled along a track form by the bogie.
According to the rail vehicle provided by the embodiment of the invention, the rail vehicle is stable in starting, fast in acceleration and low in energy loss, and the running cost can be reduced.
In some embodiments, the bogie further comprises hourglass springs (not shown) between the frame body 10 and the vehicle body, the hourglass springs being connected to the frame body 10 and the vehicle body, respectively. In other words, one end of the hourglass spring is connected to the car body, the other end of the hourglass spring is connected to the bogie frame 100, the inevitable vibration occurs during the running process of the railway vehicle, and the hourglass spring can buffer the vehicle, so that the weight of the car body is borne, and meanwhile, the shock absorption effect is achieved. The connection between the vehicle body and the frame body 10 is not limited to the hourglass spring, but may be other elastic members, such as an air spring, which has a very high vibration isolation efficiency, a small volume, and is easy to install.

The rail vehicle straddles the rail beam 300, the first magnetic suspension module 21 is adapted to the second magnetic suspension module, and the traveling wheels are adapted to be rollably supported on the upper surface of the rail beam, that is, the traveling wheels 201 are rollably supported on the upper surface of the rail beam when driven by the traveling wheels 201, and in addition, the traveling wheels 201 can be lifted from the rail beam when driven by magnetic suspension.
In connection with the above-described embodiment having the stabilizing wheels 202, as shown in fig. 3, the stabilizing wheels 202 are in contact with the side surfaces of the rail beam 300, so that when the rail vehicle turns, the rail beam 300 gives the stabilizing wheels 202 a lateral force, and the stabilizing wheels 202 transmit the lateral force to the vehicle body, thereby smoothly turning the vehicle.
Preferably, as shown in fig. 1 in conjunction with fig. 3, at least a portion of the second magnetic levitation module is opposite to the first magnetic levitation module 21 in the up-down direction so that the second magnetic levitation module provides a force in the up-down direction to the first magnetic levitation module 21. The first magnetic suspension module 21 and the second magnetic suspension module may be partially aligned, or may be completely aligned. The rail vehicle is suspended by the action force between the first magnetic suspension module 21 and the second magnetic suspension module in the vertical direction, so that the rail vehicle only rubs with air and only needs to overcome air resistance, and therefore, the energy consumption is low, and the rail vehicle can have high running speed.
In some embodiments, as shown in fig. 3, the track beam 300 includes a beam main body 301 and a beam top plate 303, the beam top plate 303 is disposed on the beam main body 301 and extends in the same direction as the beam main body, and left and right sides of the beam top plate 303 may extend out of left and right sides of the beam main body 301. That is, the upper portion of the cross section of the rail beam 300 may be T-shaped.
Specifically, C-shaped grooves are formed on the left and right side surfaces of the beam body 301, and a support portion 302 is provided between the two C-shaped grooves, wherein the running wheels 201 are rollably supported on the upper surface of the beam body 301. That is, when the vehicle speed is slow, the running wheels 201 run on the beam main body 301, when the vehicle is stationary, the running wheels 201 are supported on the beam main body, and when the vehicle speed is fast, the running wheels 201 empty.
Further, the first magnetic suspension module 21 includes two magnetic suspension modules oppositely arranged at left and right, and at least a portion of the first magnetic suspension module 21 extends into the corresponding C-shaped groove.

That is, when the rail vehicle travels at a high speed, the rail vehicle can smoothly pass through a curve by the repulsive force between the second magnetic levitation module and the first magnetic levitation module 30. For example, when the rail vehicle turns to the right, the left second magnetic levitation module repels the left first magnetic levitation module 30, i.e., the force applied to the rail vehicle to the right steers the vehicle, or, when the rail vehicle turns to the left, the right second magnetic levitation module repels the right first magnetic levitation module 30, i.e., the force applied to the rail vehicle to the left steers the vehicle. Of course, the above embodiments are merely illustrative and should not be construed as limiting the scope of the invention, for example, a rail vehicle may be provided with steering force by other means (e.g., a jet device).
In some embodiments, at least a portion of the second magnetic levitation module is opposite the first magnetic levitation module 30 in an up-down direction such that the second magnetic levitation module provides a levitation force to the first magnetic levitation module 30.
