Art field.
Background technique
Volute spring is also known as journal box spring, refers mainly to bullet with damping effect of the metal in conjunction with rubber on vehicle
Spring.Volute spring, which is mounted between rail car axle box and framework, plays support, damping noise reduction, is a kind of common rubber
The vibration and noise reducing element of glue metal composite, is mounted on the car body of vehicle single stage suspension and secondary suspension, and main function is to bear
The load of car body and framework.It is sulfided into one under certain temperature and pressure by adhesive using cone-shaped metal part and rubber
Whole, effect is that vibration damping, Noise Reduction are played using vulcanized rubber, and metalwork plays bearing and installation interface.
With the development of vehicle technology, especially urban rail, the development of subway and low floor vehicle technology, volute spring is in order to more
Meeting the demanding kinetics for guaranteeing vehicle and safety well, it is desirable that volute spring vertical stiffness has a variation rigidity, and there can be no
There is anti-S curve phenomenon in vertical stiffness.Anti- S curve, which occurs, in vertical stiffness to be the compression property due to rubber material and is tying
Rubber bodies are not using the structure design for eliminating inverse S-curve on structure, and volute spring vertically changing rigidity is too small when unloaded, and vehicle adds
When load, especially under maximum vertical load, need the rubber part of volute spring that can provide sufficiently large vertical stiffness, and real
Now ideal variation rigidity, but existing volute spring can not provide big variation rigidity again, therefore cannot achieve ideal variation rigidity, just
Anti- " S " phenomenon is presented in line of writing music；Volute spring with anti-" S " curve, rigidity is bigger under zero load, causes vehicle de-
The risk of rail.Again as volute spring be made of metal and the vulcanization of rubber it is whole, cannot dismantle also be inconvenient to carry out locally to repair
It is multiple, thus volute spring is the product of lifelong freedom from repairs.With the development of vehicle technology, fatigue load is also increasingly harsher,
Requirement to fatigue behaviour is more and more tighter, and for product under vertical load, the rubber-type face of top and the bottom is easy to appear " fold " deformation,
It forms stress to concentrate, and the vertical load of product is undertaken by rubber completely, stress and strain is all larger, finally since rubber is tired
Labor causes rubber to crack.This just need it is a kind of not only be adjusted variation rigidity, but also can prevent using when there is the Conical Projectile of fold
Spring meets above-mentioned requirements.
