Description
Technical field
The present invention relates to a kind of rail vehicle and its bogies, belong to rail vehicle field.
Background technology
For railway bogie, when passing through curve, wheel, rail are easy to wear away.It is main using radial steering
The solution wanted, i.e., realize radial function by increased guiding mechanism, but in this way but also bogie structure is complicated, again
Amount increases, therefore only just has use value on the more circuit of sharp radius curve.And for the few mostly song of small curve
Line circuit may then be lost more than gain using radial steering.Another method is to reduce the longitudinal rigidity of wheel pair, but this can lead again
Cause the linear running reduced performance of bogie.
Japan Patent JP3171197 discloses a kind of radial steering having active control radial direction mechanism, but the radial direction machine
Structure is extremely complex, and versatility is not strong.
Invention content
The present invention is intended to provide a kind of bogie, which can reduce song in the case where not increasing radial direction mechanism
Line is by the longitudinal rigidity of hour wheel pair, to improve the curve of common bogie radial through ability, with preferable diameter
To function, while ensureing not reducing the linear running performance of bogie.
To achieve the goals above, the technical solution adopted in the present invention is：
The wheel in framework both sides is arranged to axle box in a kind of bogie, including framework；It is characterized in that, the framework and phase
The wheel of side is answered to be flexibly connected by the rod assembly that can be changed by longitudinal rigidity between axle box.
It is flexibly connected as a result, by flexible linking member between axle box by the wheel in framework and corresponding side so that structure
Adaptive change can occur automatically for frame and the longitudinal rigidity taken turns between axle box（Rigidity becomes larger when linear running, curve motion
Shi Gangdu becomes smaller）, to considerably improve the curve of common bogie radial through ability, with preferable radial work(
Can, while ensureing not reducing the linear running performance of bogie.
For opposite JP3171197, the present invention is then a kind of quasi- radial steering having radial effect, and structure is very simple
It is single.
According to an embodiment of the invention, further optimization can also be made to the present invention, below the skill to be formed after optimization
Art scheme：
Preferably, rod assembly is flexible parallel connection connection structure.It is highly preferred that the rod assembly includes pull rod and vibration damping
Device；The framework is hinged and connected between axle box by the way that pull rod and damper are in parallel with the wheel of corresponding side.Drawing of the invention as a result,
Bar and damper, which will take turns, is flexibly connected axle box and framework.
Preferably, one end elastic hinge joint of the pull rod is being taken turns on axle box, the other end elastic hinge joint of the pull rod is in structure
On frame.
Preferably, one end of the damper is rigidly hinged on wheel on axle box, the other end of the damper is rigidly hinged
Architecturally.
The damper is hydraulic buffer.Due to the effect of throttle orifice, the longitudinal damping of hydraulic buffer can basis turn
Change automatically to frame operating condition：In linear section, vibration velocity is fast, and hydraulic buffer longitudinal damping is big；In curve section, shake
Dynamic speed is slow, and hydraulic buffer longitudinal damping is small.Bogie of the invention is not in the case where increasing radial direction mechanism as a result, only
Need a short-stroke hydraulic damper in parallel by the axlebox rod of common bogie, so that it may to reduce curve negotiating hour wheel pair
Longitudinal rigidity, protected simultaneously with preferable radial function radial through ability to improve the curve of common bogie
Card does not reduce the linear running performance of bogie.
The hydraulic buffer forms parallel-connection structure, longitudinal damping and the spherical rubber joint of hydraulic buffer with pull rod
Radial rigidity is superposed to the longitudinal rigidity of rod assembly.Therefore, for bogie：On curve, rod assembly longitudinal rigidity
Become smaller, causes to take turns to being prone to tend to the rotation of radial position under the action of wheel-rail creep force, to reduce wheel-rail wear；
On straight line, rod assembly longitudinal rigidity becomes larger, and causes wheel to being not easy to rotate, to ensure the stability of bogie.
Preferably, the end of the pull rod is hinged on the wheel of framework and corresponding side to axis by spherical rubber joint elasticity
On case.
The end of the damper is rigidly hinged on the wheel of framework and corresponding side on axle box by oscillating bearing.
Respectively there are one the spherical rubber joints of small radial rigidity for dress at the pull rod both ends.
The damper is the hydraulic buffer of short stroke, and respectively there are one oscillating bearings for dress at both ends.
Preferably, the framework and four wheels are connected by the rod assembly flexibility that longitudinal rigidity can be changed between axle box
It connects.
Based on the same inventive concept, the present invention also provides a kind of rail vehicles comprising car body and the steering
Frame.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is small in curve pull-up bar assembly longitudinal rigidity, and wheel shakes the head to axle box, and rigidity is small, and bogie has preferable
Radial function.Structure has taken into account curve radial direction ability and linear running stability, is suitable for the more circuit of curve, especially small
The few more curve circuits of radius curve, can be substantially reduced wheel-rail wear.
The bogie of the present invention is not in the case where increasing radial direction mechanism, it is only necessary to by the axlebox rod of common bogie
A short-stroke hydraulic damper in parallel, so that it may to reduce the longitudinal rigidity of curve negotiating hour wheel pair, to improve common turn to
The curve of frame with preferable radial function, while ensureing not reducing the linear running of bogie radial through ability
Energy.
