Non-adhesion driving structure for straddle type railway vehicle

Abstract

The invention discloses a non-adhesion driving structure for a straddle type railway vehicle. The structure comprises a monorail runway track and a bogie which are matched with each other, and is improved in that: the two sides of the monorail runway track are provided with an induction plate respectively; the two sides of the bogie are provided with a linear motor respectively; and the linear motors and the induction plates correspond one to one, and are arranged opposite. The non-adhesion driving structure has the advantages that: the adhesion driving of the conventional straddle type railway vehicle is changed into non-adhesion driving, and the braking and acceleration of the vehicle are finished by an interaction force between the linear motors and the induction plates, so the load of a traveling wheel is decreased, the stability of the structure is improved and the running cost of the vehicle is decreased.

Description

technical field [0001] The invention relates to an urban rail transit device, in particular to a non-adhesive driving structure of a straddle-type monorail traffic vehicle. Background technique [0002] Straddle Type Railway is characterized by supporting, stabilizing and guiding the car body through a single track, and the car body rides on the track beam; similar to conventional railways, straddle type monorail The transportation system is also composed of lines, vehicle systems, electromechanical equipment, depots and comprehensive maintenance bases. At the same time, as a kind of technologically advanced urban rail transit, the structure of some parts of the straddle monorail system has its own uniqueness, and the particularity of its structure mainly lies in the line and vehicle system. [0003] Line features: The straddle-type monorail railway usually adopts a fully enclosed elevated system, and its line part includes monorail track beams, pillars, elevated statio...

AI Technical Summary

Problems solved by technology

[0005] Since the existing straddle-type monorail vehicle adopts the wheel-rail adhesion driving method, the axle connecting the bogie and the running wheels must be fixedly connected with the power output shaft of the power system, and once the power system is installed, unless the car body is destructive Otherwise, it is impossible to disassemble the axle. During the operation of the vehicle, the running wheels continue to wear, and the running wheels need to be replaced regularly. In order to replace the running wheels, the axle can only be connected by cantilever. Leave a gap for the disassembly operation of the running wheels; due to the aforementioned structural characteristics, in the daily maintenance of the bogie, only the running wheels can be replaced. If the axle needs to be replaced, the cost is huge, time-consuming and labor-intensive ; Compared with the simply supported beam structure, the cantilever structure has poor structural stability and high requirements on the strength of the axle, resulting in a large bogie weight and poor vehicle stability

At the same time, the existing power system still has the defects of bulky and complex structure.

[0006] Existing straddle-type monorail vehicles driven by transmission shafts also have the following disadvantages except the aforementioned defects: 1. Poor adaptability to climate, suc
