Technical field
The invention belongs to rail vehicle elastic element technical fields, and in particular, to a kind of rubber bushing used for rail vehicle
And its assemble method.
Background technique
Rubber bushing is a kind of connecting element of function admirable of rubber and metal composite.Flexural pivot mainly utilizes vulcanization rubber
Glue plays cushioning buffer effect, and metalwork plays a part of to support and install interface, which can bear complicated working environment, wherein
Fatigue effect and instantaneous mechanical shock including multi-loads such as axial direction, radial direction, torsion, deflections.Therefore, rubber bushing is extensive
Apply to rail vehicle field.Currently, rubber bushing using structure the most universal be followed successively by from inside to outside metal core axle,
Rubber layer and metal-coating, although the performance of this structure is able to satisfy the use of various operating conditions substantially.But when the radial direction of rubber
When smaller with axial rigidity, above structure is unable to satisfy performance requirement.
But existing rubber bushing, since its rubber quasi spline is unreasonable, rubber free area is small, product with pressure
In the case that contracting and radial direction are loaded, the rubber-type face of end face is easy to appear bending deformation；Meanwhile end face rubber is easy to appear pleat
It wrinkles and bloats, finally since stress concentration causes rubber to crack, and rubber is low with the degree of adhesion of metal, and service life is short, for
Axial direction, radial direction, torsion and the various fatigue effects of deflection and the endurance of mechanical shock are limited.
