Problems solved by technology

The main problems are: the efficiency of the AC motor is low under the operating condition of low speed
Since the excitation magnetic field is generated by the excitation coil, the size of the motor is relatively large, and the heat is serious, and the gearbox is used for deceleration, which makes the overall structure of the bogie complex and increases maintenance costs. Loss, thus reducing the efficiency of the drive, and the noise is larger when vibrating
[0005] And the longitudinal distance of some suspended monorail guide wheels is too long, which is not conducive to the passage of curves

Abstract

The invention provides an inner rotor direct-driving type structure of a suspension type single-rail train. The structure comprises a framework of a bogie, wherein the framework of the bogie comprises a side frame, cross beams and a framework center platform; an air spring and a sleeper beam are arranged on the framework center platform; transverse pull rods are arranged on the front side and the back side of the sleeper beam; the sleeper beam is press-fitted on the air spring; a suspension device is a four-connecting-rod mechanism; a pair of traveling wheels is transversely arranged on each of outer sides of the side frame; guiding wheels are arranged at two ends of the side frame; and an inner rotor type permanent-magnet motor for providing rotating power for the traveling wheels is arranged between each pair of the transverse traveling wheels. According to the structure, the inner rotor type direct-driving motors are used as driving devices of the bogie, so that the energy conversion efficiency is greatly improved; and meanwhile, the size and the heating value of the motors are reduced, the structure of the bogie is simplified, the reliability of the bogie is improved, the maintenance cost is reduced, and noise caused by the bogie during running is reduced.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, in particular to an inner rotor direct-driven structure of a suspended monorail train. Background technique [0002] With the continuous acceleration of urbanization in our country, urban traffic problems are facing more and more severe tests. The existing urban public transportation system has been unable to completely solve the problem of traffic congestion in the city. Vigorously developing urban public rail transit is an option to solve the problem of traffic congestion, but the construction cost of the subway is high, the construction period is long, and there are certain requirements for the terrain, and the construction process will cause serious damage to the existing infrastructure of the city. big impact. As a medium-capacity urban rail transit, the suspended monorail can avoid the above problems. [0003] Suspended monorail transportation has the following advantages: sho...
