Description
Technical field
The present invention relates to rail vehicles field, particularly relate to a kind of bogie frame.
Background technology
Along with the progress of science and technology, rail vehicles, because it is convenient, fast, safety, increasingly becomes
People's go off daily or transport the preferred vehicles, therefore, when the security of vehicle is by design
The problem of overriding concern.
When vehicle is by curve, generally having two indices to evaluate the derailing possibility of vehicle, one is
Cross force Q between derailment coefficients, i.e. wheel track and the ratio of vertical force P, wherein vertical force usually wheel
Weight.Train in advancing for one, the weight of himself and the load-carrying born are generally certain, institute
For delivery to wheel to weight also certain, in the case of wheel load is certain, road speed is the biggest, curve
Radius is the least, and cross force is the biggest, and derailment coefficients is the biggest, and the possibility of vehicle derailment is the biggest.But
Being when wheel load is less, a little cross force is possible to make train derail, so to pass through
Another index rate of wheel load reduction, i.e. takes turns the ratio to vertical off-load amount △ P and vertical force P, comes
Evaluate vehicle derailing possibility.In the case of wheel load is certain, taking turns the biggest to off-load amount, train more holds
Easily derail.China is the bogie of relevant criterion, such as EMUs to the design construction of bogie
Derailment coefficients to be reached is less than 0.8, and wheel off-load rate is less than or equal to 0.6.
Reducing wheel is rigidity or the natural bow changing single stage suspension to the mode that off-load amount is conventional.One is outstanding
Hang device be car structure and wheel to axle box between arrange spring and shock absorber system, be used for relaxing
The track shock and vibration to locomotive, improve the comfort level of component working reliability and passenger.Due to wheel
Off-load amount is directly proportional to single stage suspension rigidity, is inversely proportional to single stage suspension natural bow, so existing skill
Art typically by reducing single stage suspension rigidity, increases the mode of its natural bow to reduce rate of wheel load reduction,
But can cause vehicle when from empty wagons to fully loaded change, floor compartment face height change is too big and causes
The stationarity of vehicle reduces, and affects the comfort level of passenger.
Also having a kind of mode to off-load amount of taking turns that reduces is to reduce the rigidity of vehicle bogie frame.Turn to
Frame is one of most important parts on rail vehicles, its deadweight of direct bearing body and load-carrying, draws
Guide-car runs along railroad track, it is ensured that vehicle passes through curve, and has to slow down and transport from vehicle
The capable vibrations brought and the effect of impact.Bogie frame is the skeleton of bogie, turns in order to contact
The each part of frame and the power of transmission all directions, and it is used for keeping axletree position in bogie, one
As be made up of left and right two curb girders and one or several crossbeam, its middle cross beam includes end carriage.Curb girder is not
It is only to (or wheels) transmission vertical force, cross force and the main member of longitudinal force to wheel, is also used for
Regulation wheel to position.Crossbeam, for ensureing the rigidity being framed in horizontal plane, keeps the parallel of each axle
And the parts such as support traction motor.
When vehicle is when by curve, in order to prevent track the most in the outer part from the pressure of outboard wheel pair being provided
Centripetal force and cause the danger of track deformation and driving, the track in outside is often slightly higher than inner track
Some, form track superelevation, therefore, when direct of travel wheel earlier above in outside is first climbed so that
The bogie frame self connected with this wheel forms a moment of torsion, and torsional rigidity is the biggest, and wheel is to subtracting
Load rate is the biggest, and train the most easily derails.Modern locomotive bogie frame has casting and two kinds of forms of welding,
Wherein Cast Steel Frame bending resistance in vertical and horizontal plane, torsional strength and rigidity are the biggest, machining
Measuring little, material use is preferable, but requires higher to casting technique, and framework is heavier, and cost is higher.
What the bogie of China railways rolling stock was generally taked is overall welding type framework, by two curb girders and
At least one crossbeam assembly welding forms, and this overall welding type framework is lightweight, uses material economy, peace
Complete reliable and technology maturation is popularized, but the torsional rigidity of bogie is very big, when vehicle distorts at circuit
In the case of Yan Chong, it is more likely that derail, cause the injures and deaths of personnel.
In order to reduce the torsional rigidity of bogie, prior art one by change crossbeam geometry,
Using four pieces of flexible steel plates is that flexibility crossbeam and curb girder are linked together by chiasma type layout, it is achieved framework
Flexibility, but such beam structure is complicated, is difficult to arrange mounting seat, and transformation process is complicated,
Relatively costly.Prior art two uses combined type framework, and framework is made up of two curb girders and a bolster,
Bolster and left and right curb girder are hinged by rotating hinge respectively so that the motion of nodding of two curb girders discharges completely,
Thus reach the purpose that bogie torsional rigidity diminishes.But this combined type framework car existing to China
The structure of modification of bogie is relatively big, and cost is the highest.
