In other words, the two stabilizing wheel mounting portions 40 can be connected to the frame body 10, and the two stabilizing wheel mounting portions 40 on the bogie frame 100 can be arranged in a form of left and right opposite to the running wheel mounting opening 11 on the running wheel 201. After installation, the two stabilizing wheel mounting portions 40 may be disposed opposite to each other with respect to the running wheel 201. In other words, the stabilizing wheel mounting portion 40 includes two oppositely disposed left and right with respect to the running wheel mounting opening 11. A stabilizing wheel 202 can be mounted on the stabilizing wheel mounting portion 40. During operation of the rail vehicle 2, if the operation of the rail vehicle 2 deviates from the orbit, the stabilizing wheel 202 can quickly adjust the rail vehicle 2 to a suitable position to maintain the rail vehicle In the stable running state of the second, the stabilizing wheel mounting portion 40 is connected to the left and right sides of the frame body 10, the stabilizing wheel 202 functions as a guiding and stabilizing, and the stabilizing wheel mounting portion 40 is respectively disposed on the left and right sides, that is, the left and right sides of the frame body 10 Both sides have a stabilizing wheel 202, and the rail vehicle 2 can turn left or right.

The bogie 200 of the rail vehicle 2 according to the embodiment of the present application, as shown in FIG. 1 in conjunction with FIG. 3, includes a bogie frame 100, a running wheel 201, a running wheel drive member 203, a first magnetic levitation module 21, and a stabilizing wheel 202. The bogie frame 100 is the bogie frame 100 of the aforementioned rail vehicle 2 .

According to the bogie 200 of the rail vehicle 2 of the embodiment of the present application, the running wheel 201 and the magnetic drive cooperate to switch the driving form according to the vehicle speed, thereby improving the acceleration and reducing the energy loss.

Specifically, as shown in FIGS. 1 and 3, the running wheel 201 is rotatably provided on the running wheel mounting opening 11, and the axis of the running wheel 201 extends in the left-right direction, and the lower end of the running wheel 201 extends downwardly to the running wheel. Mouth 11. The running wheel drive member 203 is mounted on the drive member mounting portion 30, and the running wheel drive member 203 is coupled to the running wheel 201 for driving the running wheel 201 to rotate to drive the rail vehicle 2 to travel in the front-rear direction. The first magnetic levitation module 21 is mounted on the magnetic levitation mounting portion 20 for suspending the rail vehicle 2. The stabilizer wheel 202 is coupled to the stabilizer wheel mounting portion 40, and the axis of the stabilizer wheel 202 extends in the up and down direction.

The running wheel 201 functions as a support when the vehicle is stationary and running at a low speed, and the running wheel drive member 203 drives the running wheel 201 to rotate to drive the rail vehicle 2 to move. Wherein, the magnetic driving member and the running wheel driving member 203 are relatively independent, for example, the running wheel driving member 203 can be operated, the magnetic driving member does not operate, or the magnetic driving member can be operated, and the running wheel driving member 203 does not operate. It is possible that the running wheel drive member 203 and the magnetic drive member operate simultaneously.

For example, the acceleration of the rail vehicle 2 from the standstill may be that the running wheel drive member 203 drives the running wheel 201 to move, and the running wheel 201 drives the overall acceleration motion of the rail vehicle 2. Since the running wheel drive member 203 drives the running wheel 201 to accelerate faster and runs smoothly, the vehicle can quickly reach a predetermined speed (for example, 120 kilometers per hour), and the energy conversion rate is high, thereby saving energy and controlling cost. Of course, the acceleration of the vehicle from the standstill can also be operated by the magnetic drive member and the running wheel drive member 203, so that the rail vehicle 2 has a greater acceleration, so that the rail vehicle 2 can reach the destination faster.

When the vehicle reaches a predetermined speed (for example, 120 kilometers per hour), continuing to use the running wheel drive affects the energy efficiency of the vehicle. Therefore, when the vehicle is running at a high speed, the rail vehicle 2 can be "suspended". At this time, the running wheel 201 When it is vacated, the rail vehicle 2 cannot be driven to continue to travel, and the running wheel driving member 203 can be turned off. At this time, the running resistance of the vehicle is small, the magnetic driving member is opened, and the rail vehicle 2 is driven by the magnetic driving member to move in the front-rear direction, and the operation is stable and the noise is relatively smooth. Low, and at this time the energy conversion rate is higher, which can further save energy.

Further, when the vehicle speed is low, the running wheel 201 drives the vehicle to operate, and when the rail vehicle 2 needs to turn, the guiding and stabilizing are realized by the stabilizing wheel 202 mounted on the stabilizing wheel mounting portion 40, at which time a smaller turning radius can be allowed. Moreover, at low speeds, the running of the vehicle by the running wheel 201 has a smoother advantage over the operation of the electromagnetically driven vehicle.

After the current is supplied, the first magnetic levitation module 21 and the second magnetic levitation module 304 are attracted to each other, which is equivalent to giving the rail vehicle 2 an upward force. When the gravity of the rail vehicle 2 is balanced with the upward magnetic force, the rail vehicle 2 realizes magnetic levitation.
