Description
Technical field
The utility model belongs to high speed railway car field, and in particular to a kind of high speed motor car anti-hunting damper holder is used compound
Formula joint.
Background technology
In the prior art, in general shock absorber, due to requiring that joint stiffness is smaller, the rubber in joint is softer, thus
This torsion of elastomer connector is tangentially easily deformed with the rubber layer in swing butt joint and will not damaged；Shock absorber body is produced
Raw moment of flexure is also smaller, small to the work influence of shock absorber.Two ends in misaligning and work in order to avoid oil-pressure damper two ends
The change of relative position, the elastomer connector of smaller rigidity is typically equipped with shock absorber two ends, and it allows end installation portion incessantly
Part is with respect to shock absorber certain angle（Generally higher than 10 °）Torsion and swing, also have to the axial high-frequency percussion of shock absorber buffering and
Retardation；Because this joint design is simple, manufacturing cost is low, it is used widely on modern general shock absorber.But,
Anti-hunting damper holder requires that joint stiffness is big, while also require that it is easier to rotate, to block the dither born during it works,
Above-mentioned ball joint bearing is rigid when can not meet anti-hunting damper holder to torsion to be required.
Anti-hunting damper holder is installed between bullet train, motor-car and high ferro carbody and bogie, longitudinal direction（Before vehicle
Enter direction）A kind of shock absorber set, its effect is：The vehicle snaking motion that retardance vehicle high frequency impact of collision is caused.
On some modern age high speed railway cars, in order to block the relative motion between compartment, the device workshop shock absorber between compartment（Or chauffeur
Hold shock absorber）, according to this shock absorber two ends of its work characteristics, more and more using ball joint bearing as connector, it
The characteristics of be equally（Shock absorber）Axial rigidity greatly, but is swung, the rigidity of torsion is especially small, i.e., at this moment to shock absorber
The minimum use requirement for meeting vehicle of additional bending moment.But, anti-hunting damper holder requires that joint stiffness is big, while also requiring that it has
Certain elasticity, to block the dither born during it works, above-mentioned ball joint bearing can not meet anti-hunting damper holder pair
It is elastomeric to require.Thus, in anti-hunting damper holder, butt joint rigidity requirement is high, such as certain high ferro vehicle needs joint stiffness
For 70 KN/mm, i.e., slight joint is only had 1mm by deformation during 7 ton force, can only be rubber on slight bearing area
Be made very " hard ", can such joint equally to bear more than 10 ° of torsion and swing, reverse or swing cause joint to " hard "
The tangential stroke of rubber layer is no small to be torn, and is easily caused the damage of rubber or is disengaged with vulcanized rubber parts；In addition to vibration damping
The larger moment of flexure that device body is produced, increases stress between shock absorber inner carrier and working cylinder, abrasion is increased.In short, allowing anti-
Hunting Damper joint radial rigidity is big-rubber " hard ", be easier to rotate-" soft " again, the two contradiction, allow producer without
Followed.Therefore, how to design that a kind of axial rigidity is big, be easier to rotate and anti abrasive anti-hunting damper holder joint, into
For current urgent need to solve the problem.
