Description
Technical Field
The invention relates to the field of urban rail transit, in particular to a hinged-pin type bogie of a suspension type monorail vehicle driven by a permanent magnet motor.
Background
The urban construction in China is continuously accelerated, and the rapidly increased cargo transportation brings serious test to urban traffic systems. Urban short-distance cargo transportation generally only depends on road transportation, but a large amount of truck transportation exhaust not only pollutes the air, but also has traffic safety hidden trouble, and meanwhile, the traffic jam problem also greatly limits the road transportation efficiency. The suspended monorail train system is used as a medium-traffic urban rail vehicle for constructing a quick freight line connected with a large logistics distribution center, so that the problems can be solved, and the freight logistics efficiency is greatly improved.
The suspended monorail train system has the characteristics of large transportation capacity, high speed, high safety and the like. Meanwhile, the device is environment-friendly and can not produce tail gas pollution. Compared with a subway system, the suspension type monorail train has the advantages of short construction period and low construction cost. The suspended monorail train can be integrated into the existing public transportation system, and can basically realize zero-distance transfer with buses, subways and light rails. Because the rail is suspended in the air through steel or cement upright posts, the running of the train is basically not limited by terrain, the urban space can be fully utilized, and the road traffic is not excessively occupied. The semi-closed track can ensure that the vehicle runs normally in severe weather.
The existing suspension type monorail train adopts a driving structure of a three-phase alternating current asynchronous motor and a gear box. The main problem is that the three-phase alternating current asynchronous motor is large in volume and heavy in mass, and is matched with a gear box for use, so that the size of the bogie is oversized; meanwhile, the novel transmission device is used in combination with a coupling, so that not only is the transmission efficiency reduced, but also the problems of noise pollution, rising of maintenance cost and the like are caused. The monorail vehicle usually adopts solid or pneumatic rubber tires, has smaller axle weight and smaller loading capacity, and can not meet the requirement of cargo transportation.
