A straddle type monorail non-powered bogie

Abstract

The invention relates to the technical field of rail traffic transportation equipment, and discloses a straddle type single-rail unpowered bogie. The straddle type single-rail unpowered bogie comprises a rail. Guide wheels are arranged on the two sides of the top end of the rail, a guide support is arranged in the guide wheels, and the two ends of the guide support are movably connected in the twosets of guide wheels correspondingly in a sleeved manner. According to the straddle type single-rail unpowered bogie, through the inclination angle between the rail an each guide wheel, when a rail operating vehicle is on a bend, centrifugal force generated by the rail operating vehicle on the bend can be offset with the help of the self weight of the rail vehicle; compared with an existing bogie, due to the fact that a vertical arrangement structure is adopted by the rail and the guide wheels, stress borne by the guide wheels is large, losses are quite severe, then pressure wear borne by theguide wheels on the bend can be effectively reduced, the service life of the guide wheels is prolonged, and meanwhile the cost of daily maintenance and replacement of the guide wheels is reduced.

Description

technical field [0001] The invention relates to the technical field of rail transportation equipment, in particular to a straddle type monorail non-powered bogie. Background technique [0002] With the continuous development of social economy and technology, in order to solve the increasingly serious traffic problems in cities, rail transit has become the preferred means of transportation in major cities, and in order to adapt to the passenger flow and economic strength of some small and medium-sized cities, trams and monorails Tram has become the main mode of operation of rail transit in small and medium-sized cities. [0003] In rail transportation, the bogie, as the supporting connection system between the rail and the car, has a crucial impact on the transportation environment of the entire rail transportation. The quality of its structural performance can directly affect the transportation capacity and At the same time, the daily maintenance of the bogie has also becom...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing bogies, the structure that is vertically arranged between the guide wheels and the rails does not have any problems in straight running, but when it is in a curve because of its own speed , which will generate a relatively high centrifugal force. In order to ensure the normal operation of the operating vehicle on the track, the pressure between the guide wheel and the track can only be used to offset the centrifugal force generated, which will cause the guide wheel to be subjected to a greater pressure at the bend. The loss is serious. In order to ensure the safety and stability of the rail transit operation, it is necessary to strictly limit its running speed at the curve, which seriously affects the conveying capacity of the entire transportation system. At the same time, it is necessary to regularly maintain the guide wheels Replacement to prevent accidents due to severe guide wheel wear
