Description

Technical Field

[0001] This invention belongs to the field of rail transit vehicles, and particularly relates to a monorail suspended bogie, a monorail vehicle and a track beam structure. Background Technology

[0002] With the rapid pace of urbanization in my country, surface transportation can no longer meet the demands of public transportation, while urban rail transit systems have largely solved the problem of traffic congestion. Suspended monorail transit, as one of the typical forms of urban rail transit, has the advantages of minimal interference with surface traffic, low noise, high integration, low cost, strong climbing ability, and comfortable ride, and has therefore been widely adopted.

[0003] However, current suspended monorails use box-type steel beam track structures, which have problems such as large space occupation, complex track structure, and heavy track beams. The bogies are located inside the track beams, resulting in complex bogie structures, difficult assembly and maintenance, and the use of rubber wheels, which leads to severe wear and high replacement frequency.

[0004] Therefore, it is necessary to develop a monorail vehicle with a simple track beam structure and a simple bogie structure, which can be used not only for sightseeing in tourist attractions, but also for short-distance, low-capacity transportation needs in large communities and shopping malls. Summary of the Invention

[0005] The purpose of this invention is to provide a monorail suspended bogie, a monorail vehicle, and a track beam structure to solve the technical problems of complex structure and difficult installation and maintenance of suspended bogies.

[0006] To solve the above-mentioned technical problems, the specific technical solution of the present invention is as follows:

[0007] A monorail suspended bogie includes a frame and wheels mounted on the frame. The frame includes a first beam at the top and a second beam at the bottom, the first beam and the second beam being arranged in the direction of the length of the car body. The first beam and the second beam are connected by a boom. The sides of both ends of the first beam are provided with cantilever arms perpendicular to the length of the car body, and a wheel is mounted on one end of each cantilever arm.

[0008] The upper end face of the second beam is provided with a linear motor mover, which is arranged along the length direction of the second beam, and the area between the linear motor mover and the wheel is the track area.

[0009] Thus, the first beam, the second beam, and the boom form a vertically arranged bogie, with the track area positioned between the linear motor mover and the wheels. This creates a single-sided rail-hugging structure for the bogie of this invention. Using this single-sided rail-hugging structure significantly simplifies the structure of existing suspended bogies, facilitating installation and maintenance. Furthermore, the single-sided rail-hugging structure simplifies the track beam structure, resulting in less space required for track construction and more flexible track layout.

[0010] Furthermore, a braking device is provided between the wheels, and the braking device is mounted on the first beam. The braking device works in conjunction with the wheels to brake. Preferably, the present invention employs tread braking.

[0011] Furthermore, a stop is provided at the edge of the upper end face of the second beam.

[0012] Furthermore, the wheel is mounted on the cantilever via an axle, and the axle extends through the cantilever into the first beam, where an axle box bearing is provided inside the first beam at the extended end of the axle.

[0013] Furthermore, the first beam and the second beam are parallel to each other.

[0014] Based on the same inventive concept, the present invention also provides a monorail vehicle, which includes a car body, a monorail suspended bogie as described above is provided on the upper part of the car body, and a suspension device and a traction device are provided at the bottom of the second beam, both of which are connected to the upper end surface of the car body.

[0015] Based on the same inventive concept, the present invention also provides a track beam structure, including a track beam and support members disposed at both ends of the track beam. The upper end face of the track beam is provided with a track in the longitudinal direction, and the lower end face of the track beam is provided with a linear motor stator in the longitudinal direction. The track beam is provided with a monorail vehicle as described above. The track beam is disposed within the track area, the wheels are disposed on the track, and the linear motor mover and the linear motor stator are disposed opposite to each other.

[0016] The monorail suspended bogie, monorail vehicle, and track beam structure of this invention have the following advantages: The bogie-encircling track structure is simple, allowing for flexible route selection. It can be constructed above water bodies in tourist areas, such as large lakes and major rivers. It fully utilizes the space above the water, with the track supported by supports on the shore. While transporting tourists, it also enhances the tourist experience. It can also be constructed inside large communities and shopping malls, with the track integrated into the exterior of buildings, facilitating short-distance transport of small volumes.

[0024] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, a monorail vehicle in this embodiment includes a car body 21, and a monorail suspended bogie is provided above the car body 21. The car body 21 and the monorail suspended bogie are connected by a traction device 8.

[0026] like Figure 3 As shown, the monorail suspended bogie includes a frame 1 and wheels 3 mounted on the frame 1. The frame 1 includes a first beam 11 located at the upper part and a second beam 12 located at the lower part. The first beam 11 and the second beam 12 are arranged in the direction of the length of the car body and are parallel to each other. The first beam 11 and the second beam 12 are connected by a boom 13.

[0027] like Figure 3 and Figure 4As shown, both ends of the first beam 11 are provided with cantilever arms 14 perpendicular to the length direction of the vehicle body, and a wheel 3 is mounted on one end of each cantilever arm 14. Preferably, the wheel 3 consists of two longitudinally arranged wheels with a double-flanged structure, meaning that flanges are provided on both sides, allowing the vehicle to run along the track and preventing derailment. The wheel 3 is mounted on the cantilever arm 14 via an axle 2, and the axle 2 extends through the cantilever arm 14 into the first beam 11. An axle box bearing 9 is provided inside the first beam 11 at the extended end of the axle 2, simplifying the linear bearing arrangement and reducing the space required for the bogie.

[0028] like Figure 3 As shown, a braking device 7 is also provided between the wheels 3, which adopts tread braking. The braking device 7 is located on the side of the first beam 11. Preferably, there are two braking devices 7, and the two braking devices 7 cooperate with their corresponding wheels 3 to brake. When the braking device 7 is in action, the brake shoe of the braking device contacts the concave surface of the wheel 3 to achieve the braking effect.

The suspension device 5 is installed in the middle of the second beam 12 to provide cushioning and vibration reduction. A linear motor mover 4 is provided on the upper end face of the second beam 12, which is arranged along the length of the second beam 12. A stop 6 is provided at the edge of the upper end face of the second beam 12 to further prevent the vehicle from derailing. The area between the linear motor mover 4 and the wheel 3 is the track area 15.

[0030] like Figure 1 and Figure 4 As shown, in this embodiment, the track beam structure set within the track area 15 includes a track beam 33 and support members 31 set at both ends of the track beam 33. The support members 31 can be pillars, or they can be support beams extending from other buildings or mountains for support. Figure 1 and Figure 6 The diagram shows a suspended track structure supported by support members 31 on both sides of the riverbank. The track 32 is mounted on a track beam 33 near the outer edge. The linear motor stator 34 is fixed to the lower part of the track beam 33 by fasteners. Both the track 32 and the linear motor stator 34 are arranged along the length of the track beam 33, and the linear motor stator 34 is centered on the track 32. Preferably, the linear motor stator 34 is an aluminum induction plate. The wheels 3 are mounted on the track 32, and the linear motor rotor 4 is positioned opposite the linear motor stator 34.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown, when the present invention is used, the wheel 3 sits on the track 32, and the lateral movement of the wheel 3 is restricted by the wheel flanges on both sides. The linear motor mover 4 and the linear motor stator 34 are arranged opposite to each other, and the linear motor mover 4 and the linear motor stator 34 on the track cooperate with each other to generate traction force.
