Description

Suspended monorail vehicle hinged bogie driven by permanent magnet motor

technical field

The invention relates to the field of urban rail transit, in particular to a hinge pin bogie of a suspended monorail vehicle driven by a permanent magnet motor.

Background technique

my country's urbanization construction continues to accelerate, and the rapid increase in freight traffic has brought severe challenges to the urban transportation system. Urban short-distance freight transportation can generally only rely on road transportation, but a large number of trucks emit exhaust gas that not only pollutes the air, but also poses traffic safety hazards. At the same time, the problem of traffic congestion also greatly limits the efficiency of road transportation. As a medium-volume urban rail vehicle, the suspended monorail system is used to build fast freight lines connecting large logistics distribution centers, which can solve the above problems and greatly improve the efficiency of freight logistics.

The suspended monorail system has the characteristics of large capacity, high speed and high safety. At the same time, it is green and environmentally friendly, and will not produce exhaust pollution. Compared with the subway system, the suspended monorail has a short construction period and low construction cost. The suspended monorail can be integrated into the existing public transportation system, and can basically achieve zero-distance transfer with buses, subways, and light rails. Since the tracks are suspended in the air by steel or cement columns, the trains are basically free from terrain restrictions, making full use of urban space and not taking up too much road traffic. The semi-enclosed track can ensure the normal operation of the vehicle in bad weather.

The existing suspended monorail train adopts a drive structure in which a three-phase AC asynchronous motor cooperates with a gearbox. The main problem is that the three-phase AC asynchronous motor is large in size and heavy in weight. When used in conjunction with the gearbox, the bogie size is too large. At the same time, when used in conjunction with the coupling, it not only reduces the transmission efficiency, but also brings noise pollution and maintenance costs. rise, etc. Monorail vehicles often use solid or pneumatic rubber tires, the vehicle axle load is small, and the load capacity is small, which cannot meet the needs of cargo transportation.
