[0044] The specific embodiments of the present application have been shown by the above-described drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] To make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative labor fall within the scope of protection of the present application. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0046] In the prior art, the straddle-type monorail train is connected with the track through a bogie, and the bogie usually includes a frame body and running wheels, auxiliary wheels, a power assembly and a brake mechanism arranged on the frame body. The auxiliary wheels specifically include guide wheels and stabilizing wheels. The running wheels are in contact with the top of the track, and drive the frame body to move through the driving of the power assembly. The brake mechanism is arranged on the power assembly, and brakes the frame body by braking the power assembly, and at the same time, the auxiliary wheels are distributed on both sides of the track to provide guiding and stabilizing support for the frame body.

[0047] However, the brake mechanism is arranged on the power assembly, and the power assembly mainly includes a traction motor and a reducer arranged on the output end of the traction motor, and the brake mechanism is specifically located on a gear shaft expanded by the reducer. The rotating speed of the gear shaft is usually greater than the rotating speed of the running wheels and the auxiliary wheels. In order to ensure reliable and effective braking, the structure of the brake mechanism is usually complex.

[0048] And, since the braking mechanism rotates coaxially with the gear shaft, the braking mechanism rotates at a high speed, thereby generating wind noise, and the friction noise during braking is large. In this regard, sound insulation materials such as sound insulation cotton can be used to completely seal and cover the braking mechanism to reduce noise, but this will also make the heat dissipation of the braking mechanism after braking slower, making it difficult for the heat capacity of the braking mechanism to meet the braking demand.

[0049] In order to overcome the defects in the prior art, the monorail bogie and the train provided by the embodiments of the present application, the monorail bogie comprises a frame body and a power assembly, a running wheel, an auxiliary wheel assembly and a braking mechanism arranged on the frame body. The power assembly drives the frame body to move along the track through the running wheel, the auxiliary wheel assembly is arranged on the opposite sides of the track and rolls against the track, and the braking mechanism is connected with the auxiliary wheel assembly. In this way, when the monorail bogie needs to slow down or brake, the auxiliary wheel assembly can be braked by the braking mechanism. Compared with the prior art in which the braking mechanism is arranged at the power assembly, the braking mechanism is arranged at the auxiliary wheel assembly in the present application. Since the rotation speed of the auxiliary wheel is lower than that of the power assembly, the friction speed of the braking mechanism can be reduced during braking, thereby reducing the braking noise. At the same time, the reduction of the friction speed can make the braking mechanism accumulate less heat during braking, and since the braking noise is reduced, it is not necessary to cover the braking mechanism with noise reduction cotton, thereby effectively improving the heat dissipation rate of the braking mechanism. Ultimately, the monorail bogie and the train provided by the embodiments of the present application solve the problems of large braking noise and slow heat dissipation of the existing braking mechanism.

[0050] The content of the present application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and specifically understand the content of the present application.

[0051] Referring to Figures 1 to 3 The embodiments of the present application provide a monorail bogie applied to a single track 600, which comprises:

[0052] a frame body 100;

[0053] a power assembly 200 connected to the frame body 100;

[0054] a running wheel 300 rotatably arranged on the frame body 100 and connected with the output end of the power assembly 200, the running wheel 300 being used to roll against the top of the track 600 to drive the frame body 100 to move along the track 600 under the drive of the power assembly 200;

[0055] an auxiliary wheel assembly 400 connected to the frame body 100 and used to roll against the opposite sides of the track 600;

[0056] The brake mechanism 500 is connected to the auxiliary wheel assembly 400 to brake the auxiliary wheel assembly 400.

[0057] It can be understood that the frame body 100 straddles the single track 600 and supports the train body, and the stabilizer bar assembly 110 and the air spring assembly 120 are arranged on the frame body 100, the stabilizer bar assembly 110 is connected to the opposite sides of the frame body 100 along the extension direction of the track 600 and is connected to the bottom of the train body, so that the train body is kept stable and does not twist and skew excessively when the bogie drives the train body to turn, and the air spring assembly 120 is also arranged on the opposite sides of the frame body 100 and is connected to the bottom of the train body to provide buffering support to the train body, so that the train body is more stable.

[0058] The power assembly 200 is arranged on the frame body 100 and includes a traction motor and a speed reducer arranged at the output end of the traction motor, and the cable 130 is arranged on the frame body 100 and is connected to the traction motor to provide electric energy to the traction motor.

[0059] The output end of the traction motor is connected to the walking wheel 300 through the speed reducer, the walking wheel 300 is rotatably arranged on the frame body 100, so that the traction motor drives the walking wheel 300 to rotate through the speed reducer to adjust the speed ratio, and the rotation speed of the traction motor is greater than that of the walking wheel 300. The walking wheel 300 rolls against the top of the track 600, so that the frame body 100 can drive the train body to move along the extension direction of the track 600 when the walking wheel 300 rotates.

[0060] The auxiliary wheel assembly 400 is arranged on the opposite sides of the frame body 100 and is distributed on the opposite sides of the track 600 and rolls against the two side surfaces of the track 600, so as to provide guiding and stable support for the frame body 100, and the frame body 100 can be stably straddled on the track 600 through the auxiliary wheel assembly 400.

[0061] The brake mechanism 500 is arranged on the auxiliary wheel assembly 400 and is coaxially rotatable with the auxiliary wheel assembly 400, so that the rotation speed of the auxiliary wheel assembly 400 gradually decreases or even stops when the brake mechanism 500 brakes, so as to brake the monorail bogie.

[0062] Since the brake mechanism 500 is arranged on the auxiliary wheel assembly 400, the rotation speed of the auxiliary wheel assembly 400 is basically the same as that of the walking wheel 300, and both are lower than the rotation speed of the traction motor, so that the brake mechanism 500 has lower braking difficulty, smaller braking noise and less heat accumulation, and does not need to be coated with noise reduction material, which is more conducive to heat dissipation of the brake mechanism 500.

[0063] And, compared with the brake mechanism 500 can only be set for traction motor of power assembly 200, when the brake mechanism 500 is set on the auxiliary wheel assembly 400, multiple brake mechanisms 500 can be set according to the number of auxiliary wheels in the auxiliary wheel assembly 400, so that the number and position of the brake mechanism 500 are more flexible, and the stability of the monorail bogie brake is improved.

[0064] Therefore, the monorail bogie provided by the embodiment of the present application comprises a frame body 100, a power assembly 200, a running wheel 300, an auxiliary wheel assembly 400 and a brake mechanism 500 arranged on the frame body 100. The power assembly 200 drives the frame body 100 to move along the track 600 through the running wheel 300, the auxiliary wheel assembly 400 is arranged on the opposite sides of the track 600 and rolls against the track 600, and the brake mechanism 500 is connected with the auxiliary wheel assembly 400. In this way, when the monorail bogie needs to slow down or brake, the brake mechanism 500 can brake the auxiliary wheel assembly 400.

[0065] Compared with the prior art of setting the brake mechanism 500 at the power assembly 200, the brake mechanism 500 is set at the auxiliary wheel assembly 400 in the present application. Since the rotation speed of the auxiliary wheel is lower than that of the power assembly 200, the friction speed of the brake mechanism 500 can be reduced during braking, thereby reducing the brake noise. At the same time, the reduction of the friction speed can reduce the heat accumulation of the brake mechanism 500 during braking, and since the brake noise is reduced, it is not necessary to wrap the brake mechanism 500 with noise-reducing cotton, thereby effectively improving the heat dissipation rate of the brake mechanism 500. Finally, the monorail bogie and train provided by the embodiment of the present application solve the problems of large brake noise and slow heat dissipation of the prior brake mechanism 500.

[0066] In some embodiments, referring to Figures 1 to 3 As shown in the figure, the auxiliary wheel assembly 400 comprises:

[0067] A guide wheel 410, at least one pair of guide wheels 410 are arranged on the frame body 100 and rotate, and the guide wheel 410 is used to roll against the upper part of the opposite sides of the track 600;

[0068] A stabilizing wheel 420, at least one pair of stabilizing wheels 420 are arranged on the frame body 100 and rotate, and the stabilizing wheel 420 is used to roll against the lower part of the opposite sides of the track 600;

[0069] Multiple brake mechanisms 500 are arranged, and the multiple brake mechanisms 500 are respectively connected to the at least one pair of guide wheels 410 and / or the at least one pair of stabilizing wheels 420.

[0070] At least one pair of guide wheels 410 are rotatably arranged on the frame body 100 and clamped on the upper portions of the opposite sides of the track 600. When the monorail bogie drives the train body to rotate, the guide wheels 410 can guide the frame body 100 and the train body to stably travel along the curve of the track 600, so as to ensure the accurate guidance of the monorail bogie when running on the track 600.

[0071] At least one pair of stabilizing wheels 420 are rotatably arranged on the frame body 100 and clamped on the lower portions of the opposite sides of the track 600, i.e., the stabilizing wheels 420 are located below the guide wheels 410. The stabilizing wheels 420 can stably support the frame body 100, so as to enhance the vertical stability of the monorail bogie and make the force on the monorail bogie on the track 600 more balanced, thereby avoiding the frame body 100 and the train body from tilting or shaking when turning, and enhancing the stability of the monorail bogie when running on the track 600.

[0072] The brake mechanism 500 is arranged on the at least one pair of guide wheels 410 and / or the at least one pair of stabilizing wheels 420, so that the brake mechanism 500 can directly act on the guide wheels 410 and the stabilizing wheels 420 in contact with the track 600. By applying a braking force to the guide wheels 410 and / or the stabilizing wheels 420 through the brake mechanism 500, the running speed of the auxiliary wheel assembly 400 on the track 600 can be effectively controlled, rapid and stable parking can be achieved, and the safety of the equipment can be improved. Moreover, the brake mechanism 500 is connected to different wheels, so that flexible braking control can be achieved according to actual needs, and the number and arrangement position of the brake mechanism 500 can be adjusted.

[0073] For example, in the embodiment of the present application, the brake mechanism 500 is arranged on the pair of stabilizing wheels 420. In other embodiments, the brake mechanism 500 can be arranged on one or two pairs of guide wheels 410, or the brake mechanism 500 can be arranged on both the stabilizing wheels 420 and the guide wheels 410, which is not limited in the present application.

[0074] For example, in some embodiments, referring to FIG. 4, the guide wheels 410 are arranged in two pairs, and the stabilizing wheels 420 are arranged in one pair and located between the two pairs of guide wheels 410. Figures 1 to 3

[0075] The guide wheels 410 are arranged in two pairs, so that the four guide wheels 410 are respectively located at the four corners of the frame body 100, and the stabilizing wheels 420 are located between the two pairs of guide wheels 410, so that the two stabilizing wheels 420 are respectively located at the middle portions of the two sides of the frame body 100. In this way, the auxiliary wheel assembly 400 has a simple and compact layout, and has good guiding and supporting effects.

[0076] Further, referring to FIG. 4, the auxiliary wheel assembly 400 further comprises: Figures 1 to 3

[0077] ​​Wheel and axle mounting base 430, wheel and axle mounting base 430 is connected to frame body 100;

[0078] A wheel axle 440 is rotatably mounted on a wheel axle mounting base 430, and a guide wheel 410 or a stabilizing wheel 420 is correspondingly connected to the wheel axle 440.

[0079] The axle mounting base 430 is positioned on the frame body 100 corresponding to the guide wheel 410 or the stabilizing wheel 420. The guide wheel 410 or the stabilizing wheel 420 can be stably rotated and connected to the axle mounting base 430 through the axle 440. This makes the installation of the guide wheel 410 and the stabilizing wheel 420 more stable and reliable, avoids displacement and shaking, and has a simple and compact structure that is easy to disassemble and maintain.

[0080] Furthermore, in some embodiments, reference is made to Figures 1 to 3 As shown, the braking mechanism 500 includes:

[0081] The braked component 510 is mounted on the axle 440 and rotates coaxially with the guide wheel 410 or the stabilizing wheel 420.

[0082] Brake mounting base 520, brake mounting base 520 is connected to wheel axle mounting base 430;

[0083] Braking element 530 is disposed on braking element mounting base 520 and is used for friction braking with the braked element 510.

[0084] The braked component 510 is mounted on the axle 440 and rotates coaxially with the guide wheel 410 or the stabilizing wheel 420 to achieve synchronous braking. The brake component 530 is fixedly mounted through the brake component mounting seat 520, so that the braking force applied by the brake component 530 to the braked component 510 can be directly and effectively transmitted to the guide wheel 410 or the stabilizing wheel 420 through the axle 440, thereby improving braking efficiency.

[0085] The brake mounting base 520 is connected to the wheel axle mounting base 430, which allows the brake mechanism 500 to be integrated into the overall structure of the auxiliary wheel assembly 400. Even if multiple brake mechanisms 500 are set on the monorail bogie, the entire auxiliary wheel assembly 400 can be compact and reasonably laid out, and the brake mechanism 500 can be easily debugged and maintained.

[0086] In specific implementation, the braked component 510 includes at least one of a brake disc and a brake drum;

[0087] Brake component 530 is a brake caliper that is compatible with the brake disc, or a brake shoe that is compatible with the brake drum.

[0088] It is understandable that both brake discs and brake drums are commonly used braked components 510. This arrangement facilitates the maintenance and repair of the braking mechanism 500 and is relatively inexpensive. The specific structure will not be described in detail here. In actual implementation, the choice between brake discs or brake drums can be made based on factors such as the specific structure of the auxiliary wheel assembly 400, space constraints, and braking force requirements.

[0089] When the brake element 530 is a brake caliper that is compatible with the brake disc, the brake caliper can apply pressure from both sides of the brake disc, so that the brake disc is subjected to uniform braking force, thereby achieving efficient and stable braking.

[0090] When the brake component 530 is a brake shoe that is adapted to the brake drum, the brake shoe expands during braking and contacts the inner wall of the brake drum, which can generate a large frictional force.

[0091] Furthermore, the braking component 530 includes at least one of a hydraulic braking component, an air braking component, and an electric braking component.

[0092] Understandably, hydraulic brakes utilize the incompressible nature of liquids to achieve precise control of braking force, allowing the auxiliary wheel assembly 400 to decelerate or stop smoothly, avoiding problems caused by excessive or insufficient braking force. Air brakes, powered by compressed air, can utilize stored compressed air energy to quickly release powerful braking force when greater braking force is required, such as when the auxiliary wheel assembly 400 is carrying a heavy load or operating at high speed, effectively stopping the auxiliary wheel assembly 400. Electric brakes, based on preset programs or sensor feedback, can precisely adjust the magnitude and duration of braking force, enabling better coordination with other systems.

[0093] In practical implementation, the type of brake component 530 can be flexibly selected according to factors such as braking requirements, and this application does not impose any restrictions on this.

[0094] Furthermore, in some embodiments, reference is made to Figures 1 to 3 As shown, the diameter of the braked component 510 is smaller than the diameter of the guide wheel 410 or the stabilizing wheel 420;

[0095] The braked element 510 is configured such that, in the event of failure of the guide wheel 410 or the stabilizing wheel 420, at least one braked element 510 rolls against the track 600.

[0096] This configuration allows the outer edge of the braked component 510 to be in clearance fit with the track 600. In the event of failure of the guide wheel 410 or the stabilizing wheel 420, at least one braked component 510 can roll against the track 600 to act as a safety wheel 450, providing emergency guidance and emergency stabilization support. This improves the safety of the auxiliary wheel assembly 400, keeps the monorail bogie in a relatively stable operating state on the track 600, and reduces instability such as tilting and swaying caused by uneven force.

[0097] Furthermore, in some embodiments, the auxiliary wheel assembly 400 also includes a safety wheel 450, which is at least disposed on the guide wheel 410 or the stabilizing wheel 420 that is not connected to the braking mechanism 500. The safety wheel 450 is used to roll and engage with the track 600 when the guide wheel 410 or the stabilizing wheel 420 fails.

[0098] Therefore, safety wheels 450 can be installed on some guide wheels 410 or stabilizing wheels 420 that do not have braking mechanisms 500, providing additional safety for the entire monorail bogie and further improving the reliability and stability of the monorail bogie.

[0099] This application also provides a train, including a train body and any of the above-mentioned monorail bogies mounted on the train body.

[0100] The monorail bogie has been described in detail in the above embodiments and will not be repeated here.

[0101] The train provided in this application embodiment uses a monorail bogie. The monorail bogie includes a frame body 100 and a powertrain 200, running wheels 300, auxiliary wheel assemblies 400, and a braking mechanism 500 mounted on the frame body 100. The powertrain 200 drives the frame body 100 to move along the track 600 via the running wheels 300. The auxiliary wheel assemblies 400 are located on opposite sides of the track 600 and roll against the track 600. The braking mechanism 500 is connected to the auxiliary wheel assemblies 400. Therefore, when the monorail bogie needs to decelerate or brake, the braking mechanism 500 can brake the auxiliary wheel assemblies 400.

[0102] Compared to existing monorail bogies that place the braking mechanism 500 at the powertrain 200, this application places the braking mechanism 500 at the auxiliary wheel assembly 400. Since the rotational speed of the auxiliary wheel is lower than that of the powertrain 200, the frictional speed of the braking mechanism 500 is reduced during braking, thereby reducing braking noise. Simultaneously, the reduced frictional speed results in less heat accumulation in the braking mechanism 500 during braking, and due to the reduced braking noise, there is no need to cover the braking mechanism 500 with noise-reducing cotton, thus effectively improving the heat dissipation rate of the braking mechanism 500. Ultimately, the monorail bogie and train provided in this application embodiment solve the problems of high braking noise and slow heat dissipation of existing braking mechanisms 500.

[0103] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0104] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0105] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0106] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
