Description
Technical field
The utility model relates to rail traffic vehicles bogie truck parts, refers to that especially a kind of rail traffic vehicles anti-side rolling torsion rod forms.
Background technology
The utility model belongs to a kind of rail traffic vehicles bogie truck parts, refers to that especially a kind of rail traffic vehicles anti-side rolling torsion rod forms, and is arranged between vehicle body of railway vehicle and bogie truck.When vehicle is in the time sidewindering motion, anti-side rolling torsion rod composition together provides vehicle safety to move the required rigidity of sidewindering with vehicle secondary suspension, and the requirement that meets vehicle dynamics performance with this, guarantees the safe operation of vehicle.
The vibration (motion) of guideway vehicle mainly contains the degree of freedom vibration of six direction: stretching vibration, yaw vibration, bouncing, pitching, yawing, rolling (as shown in Figure 1).Current rail traffic vehicles bogie truck is two-stage and hangs, and anti-side rolling torsion rod composition has played the effect that adjusting vehicle sidewinders rigidity, controls vehicle rolling (motion).
The typical structure that existing track traffic forms with anti-side rolling torsion rod as shown in Figure 2, mainly consists of the following components: torsion bar axle, reverse arm, installation (support) seat, vertical connecting rod (for connection body and bogie truck).
In at present domestic and international anti-rolling torsion bar system, mount pad (strong point) is arranged on by reverse arm conventionally, sometimes mount pad is in the left side of reverse arm, sometimes on right side, but the torsion bar system of these two kinds of different structures, bearing while sidewindering moment, torsion bar axle also can bear except moment of torsion the moment of flexure that does not overlap and produce due to mount pad (strong point) and vertical force (power of vertical connecting rod transmission) simultaneously, cause torsion bar to bend under actual condition and the composite deformation of distortion, torsion bar system is under the force and deformation situation of this complexity, additionally increase the load of torsion bar axle, very easily there is fracture by fatigue in torsion bar axle, cause early failure, as shown in Figure 3.
In recent years, along with the requirement of track traffic running velocity and traveling comfort is more and more higher, operation stability to track traffic circulation performance and the vital bogie truck of traffic safety, lightweight, low noise, high reliability, easy care etc. require also more and more higher.And for realizing lightweight, the each element structure of bogie truck and car body is more and more compacter and flexible.To anti-side rolling torsion rod, except reliability consideration is more and more stricter, requirement to structure is also more and more higher, not only requires anti-side rolling torsion rod compact conformation, also requires the variation of anti-side rolling torsion rod type, simultaneously, rail traffic vehicles metal parts is more and more higher to the life requirements of parts, therefore, is necessary to design a kind of torsion bar structure system composition of balanced type, reduce the load of torsion bar axle, the life-span of improving torsion bar system is necessary.
Utility model content
The utility model provides a kind of balanced type anti-side rolling torsion rod composition used for rail vehicle, it can solve torsion bar axle bearing the problem of also bearing moment of flexure in sidewindering moment of torsion, realize zero Moment to torsion bar axle, can significantly reduce the load of torsion bar axle, thereby improve the service life of torsion bar system.
The utility model is achieved through the following technical solutions: described balanced type anti-side rolling torsion rod composition used for rail vehicle, comprise torsion bar assembly and connecting rod, described torsion bar assembly comprises torsion bar axle, reverse arm and mount pad, reverse arm is arranged on torsion bar axle, torsion bar axle connection seat, one end that described reverse arm is connected with torsion bar axle is opening shape, and described mount pad is positioned in the middle of the opening of reverse arm.
One end that described reverse arm is connected with torsion bar axle is the opening shape that comprises two support arms, and two support arms of reverse arm are connected on torsion bar axle, and mount pad is between two support arms of reverse arm.
Described reverse arm be designed to " X " type, " people " font.
The connection mode of described torsion bar axle and reverse arm is that interference fit joint, splined or polygon connect.
Two ends of described torsion bar axle connect reverse arm, and one end is that interference fit joint, the other end are that splined or polygon connect.
Described reverse arm is V shape reverse arm or pin bushing-type reverse arm.Described torsion bar axle connects with the type such as V shape, pin bushing-type reverse arm, thereby torsion bar axle can connect with polytype connecting rod assembly, has increased the coupled type of torsion bar assembly and connecting rod assembly.
Described reverse arm and torsion bar axle have two contact surfaces.
Compared with being in reverse arm side with the mount pad in existing anti-side rolling torsion rod component type, main innovate point of the present utility model is:
1) mount pad is in reverse arm, vertical force and reaction of bearing are at a point, torsion bar axle only bears moment of torsion and does not bear moment of flexure, realize zero Moment to torsion bar axle, can significantly reduce the load of torsion bar axle, reduce the flexural deformation of torsion bar axle, improve the service life of anti-side rolling torsion rod composition.
2) mount pad, in reverse arm, can play and prevent torsion bar axle end float misalignment in use.
3) because reverse arm and torsion bar axle have two contact surfaces, when one of them face is because wearing and tearing etc. are former thereby when bad contact, another contact surface can continue to play the effect of contact, can keep anti-side rolling torsion rod composition to continue to play anti-effect of sidewindering.
4) torsion shaft and reverse arm can be linked together by various ways such as interference, spline, polygons, and two of left and right reverse arm can adopt same connecting mode also can adopt different connecting modes.
The utility model for the anti-side rolling torsion rod composition of existing structure because the torsion bar axle that mount pad and reverse arm unbalance loading cause additionally bears moment of flexure, a kind of balanced type anti-side rolling torsion rod composition is provided, solve torsion bar axle bearing the problem of also bearing moment of flexure in sidewindering moment of torsion, realize zero Moment to torsion bar axle, break the structure type of existing anti-side rolling torsion rod composition, can significantly reduce the load of torsion bar axle, the service life that can improve torsion bar system.
