Traction suspension device of straddle type monorail vehicle and working method

Abstract

The invention relates to a traction suspension device of a straddle type monorail vehicle and a working method. The traction suspension device is composed of a traction device, a connecting device, damping springs, vertical dampers, a transverse damper, a side blocking device and an anti-side-rolling torsion bar; the traction suspension device has good vertical and transverse stability and good curve trafficability, and achieves the functions of bearing, guiding, traction and the like of a single-axle bogie. The traction device adopts a planar four-connecting-rod device; a longitudinal traction rod is a single traction rod and is used for transmitting traction force and braking force and adapting to displacement between a vehicle body and the bogie on a curve; the connecting device is connected with a bogie frame and the vehicle body, and the front-back nodding angle of the single-axle bogie is prevented from being too large on the premise that shock absorption is not affected; the damping springs and the vertical dampers achieve vertical buffering; the transverse damper achieve transverse buffering; the side blocking device limits overlarge transverse displacement generated between the vehicle body and the bogie; the anti-rolling torsion bar provides anti-rolling capacity, and the situation that a roll angle is too large when the vehicle body passes through a small-curve-radius rail or is affected by lateral strong wind is avoided.

Description

technical field [0001] The invention relates to a straddle-type monorail vehicle traction suspension device and working method with good vertical and lateral stability, good curve passability, simple and reliable structure, and belongs to the traction suspension device manufacturing field of straddle-type monorail vehicles. Background technique [0002] The current common straddle-type monorail bogies are divided into two-axle bogies of the Hitachi model and single-axle bogies of the Bombardier model according to the type. The Hitachi mode bogie suspension system uses membrane air springs to provide both vertical and lateral buffering functions, and the traction device uses rubber piles to transmit the longitudinal force between the car body and the bogie. The Bombardier suspension system uses hourglass rubber springs to provide both vertical and lateral cushioning. The traction device uses a spatial four-bar linkage to transmit the longitudinal force between the carbody an...

AI Technical Summary

Problems solved by technology

Since the traveling wheel of the single-axle bogie occupies the middle position, it is impossible to arrange traction rubber piles, while Bombardier’s space four-link traction device has a space structure, complex structure, high installation accuracy, difficult matching, and high cost
