Abstract

A kind of wheel set axle box device of Low Floor Light Rail Bogies left and right wheelses synchronization, including axle bridge, elastic wheel, axletree, elastic wheel connects axletree by flange face fastener, and axletree is fixed by the bearing in the bearing in axle bridge and flange connecting seat, it is characterised in that:Transmission gear wheel is folded with the middle of two sets of single-row tapered roller bearings of dead axle, fixing one by the single-row tapered roller bearing of both sides in axle bridge is used for the power transmission shaft for realizing that both sides vehicle wheel rotational speed is synchronous, power transmission shaft is provided with drive pinion, and realization drive connection is engaged by being driven gear wheel and drive pinion between power transmission shaft and axletree.The present apparatus is by the engagement of power transmission shaft and a set of big little gear being integrated in axle bridge, and coupling independent wheel bogie left and right sides wheel realizes the synchronization of both sides wheel, and then weakens flange wear, improves wheel service life, reduces vehicle maintenance cost.

Description

The wheel set axle box device of Low Floor Light Rail Bogies left and right wheelses synchronization
Technical field
The utility model belongs to low-floor light rail vehicle non-powered bogie technique field, more particularly, to a kind of bogie The wheel set axle box device of left and right wheelses synchronization.
Background technology
At present, domestic and international low-floor light rail non-powered steering framing wheel set axle box device uses independent wheel construction, to realize Car body floor face is low and Land leveling(Floor is without gentle slope)Requirement.
Traditional independent wheel bogie left and right sides wheel independently rotates, and does not have automatic centering energy when orbiting Power, thus wheel side usually reclines rail operation, and then there is serious flange wear situation, ultimately result in wheel and use the longevity Life reduction, the increase of vehicle maintenance cost.
At present, also realize that low-floor light rail non-powered, independent wheel bogie are left by mechanical device without one kind in the world Right vehicle wheel rotational speed synchronization and the wheel set axle box device containing single stage suspension.
Utility model content
In order to solve tradition
The problem of maintenance cost increase of independent wheel bogie left and right wheelses flange wear, vehicle and track, this practicality is new Type provides a kind of gear drive and power transmission shaft by being integrated in axle bridge, to couple left and right sides wheel, realizes low land The synchronous wheel set axle box device of plate light rail non-powered independent wheel bogie both sides vehicle wheel rotational speed.
To realize above-mentioned utility model purpose, the utility model provides a kind of Low Floor Light Rail Bogies left and right wheelses rotating speed Synchronous wheel set axle box device, including axle bridge, elastic wheel, axletree, elastic wheel connect axletree, car by flange face fastener Axle is fixed by the bearing in the bearing in axle bridge and flange connecting seat, it is characterised in that:The two of dead axle It is folded with the middle of set single-row tapered roller bearing in transmission gear wheel, axle bridge and fixes one by the single-row tapered roller bearing of both sides Root is used for the power transmission shaft for realizing that both sides vehicle wheel rotational speed is synchronous, and power transmission shaft is provided with drive pinion, leads between power transmission shaft and axletree Cross transmission gear wheel and drive connection is realized in drive pinion engagement.
Described axle bridge is integrated cast structure, and middle part is hollow axle body, and both sides are hollow axle box, and left and right is passed through completely It is logical.
The described hollow axle box in axle bridge both sides is provided with primary spring.
The utility model passes through the engagement of power transmission shaft and a set of big little gear being integrated in axle bridge, the independent rotation of coupling To frame left and right sides wheel, the synchronization of both sides wheel is realized, and then weakens flange wear, wheel service life, drop is improved Low vehicle maintenance cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
Embodiment
Reference picture 1, Fig. 2, wheel set axle box device is by axle bridge 1, primary spring 2, elastic wheel 3, axletree 4, flange connecting seat 5th, the bearing 6 of dead axle, the bearing 7 of dead axle, transmission gear wheel 8, drive pinion 9, power transmission shaft 10 and fixed conveyor The bearing 11 of axle is constituted.Elastic wheel 3 connects axletree 4 by flange face fastener, and axletree 4 passes through the axle in axle bridge 1 The bearing 7 in 6 and flange connecting seat 5 is held to fix.Axle bridge 1 is integrated cast structure, and middle part is hollow axle body, and both sides are hollow Axle box, left and right is completely through being the main body bearing structure for taking turns set axle box device, dead axle bearing is provided with inside axle box axle bridge 6 and the mounting seat of fixed conveyor axle bearing 11, in the alien invasion of axle box axle bridge, provided with for dead axle bearing flange connecting seat 5 mounting interface.Two sets of single-row tapered roller bearings 6,7 sandwich transmission gear wheel 8 in dead axle, are driven gear wheel 8 pass through spline fitted with axletree 4.Fixing one by the single-row tapered roller bearing 11 of both sides in axle bridge 1 is used to realize two The synchronous power transmission shaft 10 of side vehicle wheel rotational speed.By being driven gear wheel 8 and the gear of drive pinion 9 between power transmission shaft 10 and axletree 4 The mode of engagement realizes connection.
