Data shows that the first-line cities are 4, the new first-line cities are 15 (wherein daily passenger flow of super-large cities such as Beijing, Shanghai and the like are all more than 1000 ten thousand, and daily passenger flow of first-line cities such as Guangzhou, Shenzhen, Nanjing and the like are all about 800 ten thousand), the second-line cities are 30, the third-line cities are 70 and the fourth-line cities are 90. With the accompanying problems of a series of urban diseases, such as traffic jam, air pollution and difficulty in housing. This is due, on the one hand, to the imperfection of the urban infrastructure and, on the other hand, to the excessive automobile occupancy of the inhabitants. Meanwhile, air pollution is also aggravated, and the housing space is reduced due to the expansion of roads. Therefore, the effective solution to the problem of urban traffic congestion is very slow.

The rapid development of urban public transport is one of the most effective measures for solving traffic jam at present. Urban road traffic and urban rail traffic are important components of urban public traffic. Compared with urban road traffic, the urban rail traffic has the characteristics of large traffic volume, high efficiency, quickness, safety, comfort, low energy consumption, small occupied pavement space and the like. Therefore, each city is actively developing urban rail transit to reduce urban traffic pressure. Therefore, the subway is the preferred traffic system of the city at present, but the subway line construction single piece is too high, and not acceptable for all cities and all areas, but the mountain cities of China occupy one third of the total amount of the city, and the traffic of a plurality of second-line, three-line and four-line cities is moderate, thereby providing higher requirements for the adaptive capacity of the traffic system. Meanwhile, the landscape of the tourist attraction is complex, the requirement is low in environmental damage, and the requirement on the landscape of the vehicle is high.

The straddle type monorail transit has the advantages of low cost, good landscape property, strong space adaptability, space saving, convenient construction and the like, is suitable for being used as a main traffic line of mountain cities, tourism lines and two-line, three-line and four-line cities, and can also be used as a supplementary vehicle for partial areas of the first-line cities.

Meanwhile, with the continuous use of the straddle type monorail, the problems of vehicle rescue, line detection, line maintenance and the like occur, so that the requirement of the monorail line engineering vehicle comes with the problems.

The operation and maintenance environment of the straddle type monorail vehicle is diversified, and the climbing capability, tire burst safety, all-weather operation and the like of the vehicle are guaranteed. Therefore, it is an urgent technical problem to be solved by those skilled in the art to develop a novel railway bogie suitable for both railway vehicles and engineering vehicles with large axle weights.
