Description

Background
The urbanization construction of China is continuously accelerated, and the rapidly increased cargo transportation volume brings severe examination to an urban traffic system. The transportation of urban short-distance goods generally only depends on road transportation, but a large amount of truck transportation exhaust gas not only pollutes the air, but also has traffic safety hidden dangers, and the traffic jam problem also greatly limits the efficiency of road transportation. The suspension type monorail train system is used as an urban rail vehicle for medium traffic volume, is used for constructing a quick freight line connected with a large logistics distribution center, can solve the problems, and greatly improves the freight logistics efficiency.
The suspension type monorail train system has the characteristics of large transportation capacity, high speed, high safety and the like. Meanwhile, the method is green and environment-friendly, and cannot generate tail gas pollution. Compared with a subway system, the suspension type monorail train is short in construction period and low in construction cost. The suspended monorail train can be integrated into the existing public transportation system, and can basically realize zero-distance transfer with public buses, subways and light rails. Because the track is suspended in the air through the steel or cement upright posts, the train operation is basically not limited by the terrain, the urban space can be fully utilized, and the road traffic cannot be excessively occupied. The semi-closed track can ensure that the vehicle can normally run in severe weather.
The existing suspension type monorail train adopts a driving structure that a three-phase alternating current asynchronous motor is matched with a gear box. The main problems are that the three-phase alternating current asynchronous motor has larger volume and heavier mass, and is matched with a gear box for use, so that the bogie has overlarge size; meanwhile, the transmission shaft coupling is combined with a shaft coupling, so that the transmission efficiency is reduced, the problems of noise pollution, maintenance cost rise and the like are caused. The monorail vehicle usually adopts solid or inflatable rubber tires, the vehicle axle weight is small, the load carrying capacity is small, and the requirement of cargo transportation cannot be met.
