Description
Technical field
The utility model relates to arrive the modular construction and its connection type of a kind of railway freight-car, a kind of secondary framework is referred in particular to
Formula radial steering U-shaped pair framework and digonal link cross connection device；Belong to bogie of car manufacturing technology field.
Background technique:
Secondary framework type radial steering is one kind of radial steering, is intersected by two U-shaped pair frameworks with digonal link
Connect composition wheel to radial device can make bogie obtain wheel pair between anti-shearing rigidity and bending stiffness appropriate, to improve vehicle
The speed of service and curving performance.Wherein, take turns to radial device be secondary framework type radial steering significant components it
One, the lateral connection rigidity between wheel pair is on the one hand increased to radial device using wheel, on the other hand reduces wheel to shaking the head
Rigidity makes front and back wheel intercouple yaw motion, under the premise of not reducing bogie movement vibration stability, can make to turn to
Front and back wheel can tend to the direction of orbital curve radius to axis when frame passes through curve, reach wheel to radiai adjustment, reduction wheel track
The purpose of active force.Currently, the secondary framework type radial steering wheel in China is to radial device by 2 secondary framework U-shaped arms and intersection
Connecting rod interconnection forms, and interconnection bar is to transmit front and back wheel to play the pass of bogie performance advantage to horizontal interact
Key member；Under normal circumstances when emergency brake of vehicle, the impact of generation is maximum, and interconnection bar stress is also maximum, therefore holds very much
It easily goes wrong, leads to the traction failure of interconnection bar, therefore how to improve U-shaped arm and interconnection bar cross-connection system
For guaranteeing the key of interconnection bar normal use.It is necessary to be studied this.
The patent literature report for not finding there is with the utility model same technique by patent retrieval, has with the utility model
The patent of certain relationship mainly has following:
1, the patent of invention of Publication No. CN104325992A provide it is a kind of it is easy for installation, be able to achieve U shape pair framework with it is right
The structure of brail gapless elastic connection.Its technical solution is as follows:
The program is to be equipped with core at digonal link both ends to connect U-shaped pair framework and digonal link, key technology
Shaft mounting hole fills elasticity hinge in mandrel mounting hole internal pressure, and elasticity hinge is that outer ring steel bushing and inner ring steel bushing, In are set in the middle part of mandrel
Vulcanised rubber layer between mandrel, outer ring steel bushing and inner ring steel bushing is provided with hinge hole on U shape pair framework, pair with flexible hinge
Brail end is located in hinge hole.But the patent still has following disadvantage:
1) elasticity hinge is bolted on the inner cavity of secondary truck transom, and elasticity hinge is if there is rhegma or mistake in utilization
Effect, inspection personnel are difficult to find there is very big security risk to daily driving；
2) resilient bushing outer ring is fitted in the circular hole of digonal link both ends, while resilient bushing is bolted on secondary structure
The inner cavity of frame crossbeam, when bogie passes through curve, since there are torsion stiffness for resilient bushing rubber, so influencing bogie two-wheeled
Pair radial through performance, increase wheeling edge wearing.
3) U shape pair truck transom and the fixed position of digonal link are too close from U shape pair framework longitudinal centre line, and vehicle is being made
When impact of collision occurring during dynamic, U shape pair truck transom stress can be very big, so U shape pair truck transom is needed in design
The influence for considering rigidity and intensity causes U shape pair frame design weight to increase, to increase bogie unsprung mass, reduces
Dynamics of vehicle performance.
