Description
Technical Field
The invention belongs to the field of special bogie devices for railway vehicles, and particularly relates to a linear induction motor bogie with a wheel adjusting function.
Background
In order to meet the actual demands of different working conditions, the bogie structure of the rail train has evolved into a huge family with various functions, and the core design concept of the bogie structure of the rail train needs to consider the structural forms of traction and braking modes, primary and secondary damping systems, and also needs to comprehensively consider systematic factors including but not limited to structural strength, total weight, feasibility of materials and processing methods, minimum passing curve radius and the like. The structural form of the train bogie is continuously evolved to be replaced and replaced, each time significant structural innovation or obvious process improvement is realized aiming at a brand new design concept, and the old structural form is often replaced and eliminated by a new structure rapidly.
The linear induction motor driven railway vehicle can change the driving force of the train when the train moves forward from the adhesive rolling friction force between the steel wheel and the steel rail to the electromagnetic coupling force between the induction motor and the linear guide rail, thereby further enhancing the climbing capacity of the railway vehicle and enabling the adaptability of the vehicle to the terrain to acquire qualitative leaps again. Therefore, the linear induction motor driven railway vehicle not only maintains the technical advantages of the traditional steel wheel-steel rail track traffic train, but also can avoid the technical weaknesses of the rubber wheel monorail and other traffic systems, thereby laying a foundation for the wide application of the linear induction motor driven railway vehicle in the three-dimensional track traffic systems with complex terrains such as underground railways, overhead lines, ground lines and the like.
However, in order to ensure that the driving electromagnetic force generated by the linear induction motor meets the preset requirement, the exciting air gap between the induction motor and the linear guide rail must be more strictly controlled within a given vertical range, but the requirement presents great challenges to the layout position and vibration reduction mode of the induction motor on the framework, and the existing vibration reduction modes of the rigid motor hanging seat, the swing bolster vibration reduction mechanism based on the secondary steel spring and the air spring used by the traditional bogie, even the newly proposed herringbone primary spring and the like in recent years cannot meet the design requirement of the exciting air gap on a smaller vertical vibration interval due to the overlarge vibration amplitude in the plumb direction.
Therefore, how to develop a new bogie suitable for a linear induction motor train, ensure that the height value of the exciting air gap between the induction motor and the linear guide rail is within a given interval, ensure the structural strength of the framework, and simultaneously fully release the vibration and stress among all the large parts of the bogie, has become a research and development subject to be overcome.
The central symmetry plane refers to a virtual cross-sectional plane which can symmetrically divide an object with a symmetry structure into two parts which are mirror images of each other, and a line segment formed by connecting any two symmetry points which are mirror images symmetrical with respect to the central symmetry plane on the object is formed, wherein the midpoint of the line segment is positioned on the central symmetry plane.
Disclosure of Invention
In order to solve the problem that the existing bogie with the traditional structure uses rigid motor hanging seats, the existing vibration damping modes such as a swing bolster vibration damping mechanism based on a secondary steel spring and an air spring, a primary spring shaft box and the like have overlarge amplitude in the plumb direction, so that the design requirement of an excitation air gap on a smaller vertical vibration interval cannot be met; and the prior various bogie structures can not achieve the technical problems of better consideration and balance in the aspects of reducing the total weight, improving the structural strength, increasing the layout space of the framework, reducing the vibration amplitude, improving the passing radius of the minimum curvature line, and the like.
