Suspension type monorail vehicle and suspension device thereof

Abstract

The invention provides a suspension type monorail vehicle and a suspension device thereof. The suspension device of the suspension type monorail vehicle comprises a suspension rod used for being connected with a vehicle body in a suspended mode; a first buffer structure capable of buffering longitudinal swing of the vehicle body, wherein one end of the first buffer structure is connected with thesuspension rod, and the other end of the first buffer structure is used for being connected with a bogie of the suspension type monorail vehicle; and a second buffer structure capable of buffering transverse swing of the vehicle body, wherein one end of the second buffer structure is connected with the suspension rod, and the other end of the second buffer structure is used for being connected with the bogie. During application, the other end of the first buffer structure is connected with the bogie of the suspension type monorail vehicle, and the other end of the second buffer structure is connected with the bogie; and in the working process of the suspension type monorail vehicle, the first buffer structure can restrain longitudinal swing of the vehicle body and buffer longitudinal swingof the vehicle body, and the second buffer structure can restrain transverse swing of the vehicle body and buffer transverse swing of the vehicle body, so the problem of transverse swing of the vehicle body is solved.

Description

technical field [0001] The invention relates to the technical field of rail transit trains, in particular to a suspended monorail vehicle and a suspension device thereof. Background technique [0002] As a unique type of rail transit train, the suspended monorail vehicle is different in structure from the traditional steel-wheel rail vehicle. The bogie of the suspended monorail vehicle is located above the car body, and the car body is suspended on the bogie. The suspension device is the only force transmission part between the car body and the bogie. The suspension device transmits the force and relative motion between the car body and the bogie. The suspension device is related to the running safety and ride comfort of the suspended monorail vehicle. [0003] Because the car body of the suspended monorail car is suspended on the bogie, the car body will swing laterally (perpendicular to the forward direction of the vehicle) when the vehicle passes through a curve or the bo...

AI Technical Summary

Problems solved by technology

[0003] Because the car body of the suspended monorail car is suspended on the bogie, the car body will swing laterally (perpendicular to the forward direction of the vehicle) when the vehicle passes through the curve or the bogie is subjected to lateral excitation and wind force, resulting in reduced ride comfort

However, the existing suspension device only uses two air springs arranged longitudinally (that is, parallel to the forward direction of the vehicle) to achieve vibration reduction, which has a poor suppression effect on the lateral swing of the vehicle, and the problem of lateral sway of the vehicle body cannot be improved.
