Embodiment 1

[0022] see figure 1 , is a schematic diagram of a bogie with a rim direct-drive motor for a straddle-type monorail train provided in Embodiment 1 of the present invention. The bogie with a rim direct-drive motor provided in Embodiment 1 includes a The drive motor, the motor stator 9 of the drive motor is fixedly connected to the axle 3, the motor rotor 8 of the drive motor is fixedly connected to the motor housing 5, the motor housing 5 is rotatably connected to the axle 3, and the motor housing 5 is connected to the running wheel (not marked in the figure) fixed connection.

[0023] During the working process, the motor stator 9 of the drive motor is energized, and the drive motor rotor 8 rotates. Since the motor rotor 8 is fixedly connected to the motor housing 5, the motor housing 5 is rotatably connected to the axle 3 and is fixedly connected to the running wheel , so the running wheels rotate together with the motor rotor 8. It can be seen that the bogie with the rim dir...

Embodiment 2

[0031] see figure 1 , In the first embodiment, the axle 3 is a simply supported beam structure, one end of the axle 3 is fixedly connected to the first side beam 1 , and the other end is fixedly connected to the second side beam 2 . The difference between the second embodiment and the first embodiment is only that the structure of the axle is different. In the second embodiment, the axle adopts a cantilever structure.

[0032] In the above embodiments, the bogie may be provided with only one axle 3 or two axles 3 .

[0033] The present invention also provides a straddle type monorail train, which comprises the bogie disclosed in the above embodiments. Since the bogie disclosed in the above embodiment has the above-mentioned technical effects, the straddle-type monorail train having the bogie also has the above-mentioned technical effects, which will not be repeated here.

Abstract

The invention provides a straddle type monorail train and a bogie with a rim direct drive motor. The bogie comprises a driving motor arranged on an axle (3), wherein a motor stator (9) of the drivingmotor is fixedly connected with the axle (3); a motor rotor (8) of the driving motor is fixedly connected with a motor shell (5); the motor shell (5) is in rotatable connection with the axle (3); themotor shell (5) is fixedly connected with a walking wheel. A driving system is not required by the bogie provided by the invention and the walking wheel is directly driven by the driving motor, so that the driving efficiency is increased, the driving device is compactly arranged, the reducing of the volume of the bogie is benefited and the weight of the bogie is reduced.

Description

technical field [0001] The invention relates to the technical field of monorail trains, in particular to a straddle-type monorail train and a bogie with a wheel rim direct drive motor. Background technique [0002] At present, the bogie driving device of straddle monorail trains usually uses a two-stage reduction gearbox to transmit power, which not only causes the bogie to be bulky and heavy, but also has the disadvantages of low transmission efficiency and complicated installation process. Therefore, how to improve To reduce the volume of the bogie and improve the transmission efficiency of the bogie driving device of the straddle-type monorail train has become a technical problem urgently to be solved by those skilled in the art. Contents of the invention [0003] In view of this, the present invention provides a straddle-type monorail train and its bogie with a rim direct drive motor. The driving device of the bogie has high transmission efficiency and is compactly arr...
