Description
Technical field
The utility model relates to a kind of rail traffic vehicles sectional type shearing-type elastic wheel, belongs to light rail vehicle elasticity carWheel technical field.
Background technology
Along with becoming increasingly conspicuous of urban transport problems, city railway vehicle is because of its economy, environmental protection, the advantage such as convenient, comfortable,Become the important selection of urban transportation. Elastic wheel is setting-in vibration isolation rubber between the rim of wheel and core wheel, relies on rubberDamping effect, play and reduce wheel-rail impact noise, relax wheel-rail impact vibration, improve passenger's riding comfort. ExistingFlexible wheel can be divided into pressure-bearing type, shearing-type and pressure according to the bearing mode of vibration isolation rubber and cut compound three types. Pressure-bearingThe rubber element of type elastic wheel mainly bears radial pressure load, and radial rigidity is larger, and bearing capacity is strong, but due to axiallyRigidity is too low, causes curve passing through security poor. The vibration isolation rubber of shearing-type elastic wheel and wheel rolling plane approximation are flatRow layout, rubber mainly bears shear-type load, and radial rigidity is very low, has excellent vibration damping and anti-acoustic capability. Pressure is cut multipleThe rubber element of mould assembly elastic wheel is the V-structure with certain angle, can bear compression and shear-type load simultaneously, knotStructure is simple, stable performance.
Along with the development of technology, the parts such as bogie dynamical system, brakes are more and more directly installed on wheel to upper,Particularly low-floor tramcar is in order to reduce vehicle floor face height for city rail vehicle simultaneously, and part bogie even only adopts oneThe mode that level hangs, causes bogie unsprung mass increasing, and vehicle wheel track dynamic force and wheel track noise sharply increase,This just requires wheel must have lower radial rigidity, to relax Vehicular vibration, improves passenger's riding comfort. Therefore,Radial rigidity shearing-type elastic wheel low, that have excellent vibration and noise reducing performance is widely applied.
Early stage shearing-type elastic wheel vibration isolation rubber is directly compressed in wheel die cavity, after long-time use due to rubber stressLax, cause precompression to decline, easily there is slippage inconsistent phenomenon in wheel. For solving wheelslip problem, the later stage develops againRubber parts and wheel metalwork integrated vulcanizing structure, but this complex structure, manufactures maintenance cost higher. And CN103707711A disclosed " rail traffic vehicles shearing-type elastic wheel " is by two integrated elastic dishes and wheelThe shearing-type elastic wheel of the heart, rim and pressure ring composition. But the elasticity of the damping element in above-mentioned shearing-type elastic wheel schemeBody is overall circulus, in the time that wheel diameter or profile interface change, need to redesign manufacture elastomeric mould andProduct, cannot realize general in different wheel of damping element, has increased exploitation and the manufacturing cost of wheel.
