Description
Technical field
Be vibration damping field the present invention relates to rail traffic vehicles one, relate generally to it is a kind of adjust one be rubber spring rigidity and
The method and products thereof of radial preshrunk amount is the rigidity of rubber spring and radial precompressed amount for adjusting one.
Background technology
One is the spring with damping effect that rubber spring refers mainly to metal-rubber combination, and applied to vehicle, one system subtracts
It shakes.One is that rubber spring is mounted between rail car axle box and framework and plays support, damping noise reduction, is common one
The compound vibration and noise reducing element of kind rubber-metal, is mounted on the car body of rolling stock single stage suspension, and main function is to bear vehicle
The load of body and framework.One entirety is sulfided by adhesive using metalwork and rubber under certain temperature and pressure,
It is to play vibration and noise reducing using vulcanized rubber that it, which is acted on, and metalwork is for supporting and installing interface.With rolling stock technology
Development, the especially development of high ferro EMU, urban rail, subway and low floor vehicle technology, one is rubber spring in order to preferably
Meet the demanding kinetics for ensureing vehicle and safety, it is desirable that one, which is rubber spring, has smaller vertical and lateral stiffness, compared with
Big longitudinal rigidity, medium and small vertical stiffness are conducive to improve the comfort of vehicle operation, small lateral stiffness and big vertical
Be conducive to the operation stability of vehicle to rigidity and cross curve ability.
Since rubber product has the characteristic of resistance to compression not tension, for the stretcher strain for offsetting during product use, make production
Product are constantly in compressive state, it will usually carry out precommpression design to rubber product, achieve the purpose that improve product service life.
It is rubber spring existing one, since mandrel, partition board and housing are the structures with cone angle, therefore under vertical zero load, still
There is radial component to realize the radial precompressed of product.With the development of current track traffic, especially city train and height
The development of fast train, to more stringent requirements are proposed in the security reliability of vehicle operation, comfort and service life.Comfortable
Property aspect, product vertical stiffness is smaller, and the damping effect that can be realized is better.The simplest mode of reduction of vertical stiffness is to reduce
The cone angle of mandrel, partition board and housing adjusts cone angle angle as shown in Figure 1, the cone angle of mandrel, partition board and housing is about 10 ° -30 °
Degree can realize that product is vertical, adjusting of radial rigidity, meet the different-stiffness requirement of product.In product loading, product
It is vertical empty wagons load F to be distributed to radial component as F1 by the precompressed of empty wagons load F, cone angle, while being provided to be radial
Precommpression.When vertical stiffness requires very little, the cone angle of mandrel, partition board and housing needs the very little designed, in some instances it may even be possible to occur
The phenomenon that cone angle is close to 0.At this point, one is the component F1 meeting very littles of unloaded load F after rubber spring entrucking, lead to the diameter of rubber
Reduce to decrement.When radial stand under load, when radial deflection is more than radial pre compressed magnitude, the rubber in the radial direction of product
Glue, which will appear, pulls deformation, and this elongation strain pole is unfavorable for the fatigue life of rubber product.
