Description
Technical field
The utility model relates in anti-side rolling torsion rod for connecting the connection structure of reverse arm and connecting rod.
Background technology
Along with rail traffic vehicles, particularly the running velocity of motor train unit vehicle, traveling comfort and security requirement are more and more higher, require also more and more stricter when designing bogie truck to its structural behaviour and damping noise reduction, this proposes new requirement to the properties of anti-side rolling torsion rod, in the structure of anti-side rolling torsion rod, the node that existing reverse arm is connected with connecting rod is generally metal joint bearing, adopts diplopore mount pin or bevel-type mount pin to connect.Reverse arm is connected with connecting rod by two bolts by diplopore mount pin; Bevel-type mount pin be mount pin in reverse arm, by mount pin being penetrated the taper hole of reverse arm, and reverse arm is connected with connecting rod by fastening mounting nuts.
Adopting the node of metal joint bearing, is that the connection mode of diplopore mount pin or bevel-type mount pin all can not provide good effectiveness in vibration suppression.And metal joint bearing does not almost have deflection stiffness and torsional stiffness, can not turn round voluntarily when connecting rod deflects or reverse.
Utility model content
the utility model provides a kind of and has certain deflection stiffness and torsional stiffness can be turned round voluntarily when connecting rod deflects or reverse and the connection structure of the better reverse arm of effectiveness in vibration suppression and connecting rod.
For achieving the above object, the technical solution adopted in the utility model is: the connection structure of reverse arm and connecting rod, comprise U-shaped connecting portion and rod end bearing, U-shaped connecting portion is arranged on the end of reverse arm, rod end bearing is connected with the threaded one end of connecting rod, it is characterized in that described rod end bearing has rubber-metal sandwich structure, the bearing end of described rod end bearing is placed in described U-shaped connecting portion, and U-shaped connecting portion is connected with rod end bearing through described rod end bearing by described pin assemblies.
Further, described pin assemblies comprises guide, pin and nut, two sidewalls of described U-shaped connecting portion all have through hole and two through hole alignment settings, guide described in two is contained on through hole respectively, described pin is through described guide and rod end bearing, and pin one end is stretched out and uses fastening nuts from guide.
Further, described rubber-metal sandwich structure comprises rubber layer and the metal level of cross laminates setting successively, and described rubber layer is connected with metal level sulfuration.
Further, described U-shaped connecting portion is by being processed to form described reverse arm end.
In the utility model, U-shaped connecting portion is arranged on the end of reverse arm, rod end bearing is threaded with connecting rod, U-shaped connecting portion is connected by pin assemblies with rod end bearing, rod end bearing has rubber-metal sandwich structure, when the vehicle is running, connecting rod moves up and down and vibrates with the vibration of vehicle, the kinetic energy of a rubber-metal sandwich structure Absorbable rod part in rod end bearing, reduce the vibration of rod end bearing, thus reduce the vibration of reverse arm and link joint feature position, make the effectiveness in vibration suppression of reverse arm and link joint feature position better.U-shaped connecting portion is connected with rod end bearing through rod end bearing by pin assemblies, when connecting rod deflects or reverse, rubber-metal sandwich structure in rod end bearing is that rod end bearing provides certain deflection stiffness and torsional stiffness, after the rotation of rod end bearing generation certain angle, the elastic resilience of rubber-metal sandwich structure makes rod end bearing to turn round voluntarily, improves the reliability of connecting rod during vehicle operating.
