Quality, the single quality system of spring-damp system replacement originally are spent, not only reduces the dynamic deformation from motion of wheel track, wheel and rail in this way
Road vibration amplitude also correspondingly reduces, and has slackened generated noise between wheel track.
Traditional elastic wheel is divided into compression-type, shearing-type, cuts compound three kinds of pressure.The radial elastic of compression-type elastic wheel
Deficiency, and axial elasticity is excessive；And although radially, axially elasticity is close for shearing-type elastic wheel, when being run on curve, bullet
Property element（Rubber）On one side tension, while be pressurized, tensile stress will cause elastic element to destroy rapidly；What is developed on this basis cuts
Composite elastic wheel is pressed, " V " shape rubber elastic element is used, compression will be generated simultaneously under load effect and shearing becomes
Shape.And " V " type rubber elastic element different angle is pressed, axial and radial stiffness can be made to obtain best match, pressure and cut
Power obtains an equitable breakdown.
It is to prevent rubber elastic element from sliding that tradition, which cuts pressure composite elastic wheel, generally by rubber elastic element and core wheel
Component, wheel hub directly vulcanize into a single integrated structure, such a structure increases the manufacturing difficulty of wheel, need large-scale rubber sulphur
Change equipment, production cost is higher.Meanwhile rubber is attrition component, when replacement, needs to replace entire wheel, maintenance cost compared with
It is high.In addition, the elastic element that tradition cuts pressure composite elastic wheel is usually integral structure component, disassembling, assembling and replacing repairs very not
Just.
