Description
Technical field
The utility model relates to a kind of elastic wheel, specifically be that elastic wheel is used in a kind of track traffic.
Background technology
Be accompanied by the development of urban rail transit in China, the extensive construction of city underground, light rail is used, and the vehicle operating noise problem has constituted the resident and has a strong impact on.Elastic wheel is a damping element of between metal piece, inlaying compressive state, vibration and noise in the time of can effectively reducing vehicle ', and the compressive state through the adjustment damping element can change the rigidity of elastic wheel, the performance of adjustment elastic wheel.
And what generally adopt between the elastic wheel metal piece that uses now is bolted structure; This structure has very high requirement to bolt strength; When some bolts in one group of bolt because quality or external force problem are when taking place to lose efficacy; Remaining bolt will bear more pulling force, more be prone to the generation accident.Bolted elastic wheel is owing to safety factor, and bolt needs consistent predetermincd tension, often need buy special-purpose torsion machine, and cost is higher.Simultaneously, because damping element needs periodic replacement, bolt generally has anti-loosening structure, is not easy to remove and install, and this periodical maintenance for elastic wheel is changed the more work amount of also bringing.100% present low-floor light rail vehicle is often taken turns the footpath below 600mm, obviously reduces with respect to former elastic wheel wheel footpath, and this just requires its compact conformation.What often adopt now is smaller szie, and the bolt of greater number connects, and this performance and installation process for bolt is all had higher requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of compact conformation and track traffic safe and reliable, that be easy to remove and install, practice thrift cost to use elastic wheel.
The technical scheme that realizes above-mentioned purpose is: elastic wheel is used in a kind of track traffic, comprises core wheel assembly, vibration-damped component and has the rim of centre hole, and damping element is between core wheel assembly and rim; The core wheel assembly is positioned at the centre hole of rim; And have gap S between core wheel assembly and the rim, the core wheel assembly comprises flange and the core wheel with hub bore, and core wheel has annular slot; The inner hole sleeve of flange is on the bottom surface of the annular slot of core wheel; Have annular slot on the bottom surface of said annular slot, snap ring is housed in the annular slot, the outside of snap ring and flange offsets.
The hole wall middle part of the centre hole of said rim has radial ringed convexity.
Common looping cavity volume between said core wheel assembly and the rim; The cross-sectional plane of ring-shaped chamber is V-shaped; Said damping element comprises the first annular damping ring and the second annular damping ring that is arranged symmetrically in the ring-shaped chamber; And the cross-sectional plane after the first annular damping ring and the second annular damping ring make up in ring-shaped chamber is also V-shaped, and said radial ringed convexity is inserted in the junction of the first annular damping ring and the second annular damping ring.
Common looping cavity volume between said core wheel assembly and the rim; The cross-sectional plane of ring-shaped chamber is V-shaped; Said damping element comprises several damping blocks that circumferentially are distributed in the ring-shaped chamber; The cross-sectional plane of each damping block is V-shaped, and all has position-limited trough on several damping blocks, and said radial ringed convexity is inserted in the position-limited trough of several damping blocks.
The quantity of said damping block can be 6 ~ 18.
The quantity of said damping block is preferably 12.
Said flange have the inclined-plane with adjacent snap ring, and the angle between the bottom surface of the annular slot of inclined-plane and core wheel is 30 ° ~ 60 °.
Angle between the bottom surface of the annular slot of said inclined-plane and core wheel is 40 ° ~ 50 °.
After adopting the structure of technique scheme, because the inner hole sleeve of flange has annular slot on the bottom surface of said annular slot on the bottom surface of the annular slot of core wheel; Snap ring is housed in the annular slot; The outside of snap ring and flange offsets, and after use snap ring structure substitutes the bolted connection of prior art, only need use hydraulic efficiency gear to promote snap ring during installing/dismounting and just can snap ring installed or dismantle; Be easy to dismounting, reliability is high; And the wheel behind the use snap ring is than making bolt together can bear bigger axial and shearing load: show according to data; The load that guarantees of one 10.9 grades M16 bolt is 102000N; Considering safety factor, bolt pretightening and guaranteeing under the prerequisite of all bolt torques unanimities in the bolt group; Actual external load of bearing should be below 50000N, and the snap ring of diameter about 380mm, can bear axially and shearing load all more than 1500000N; And need not to consider needed moment of torsion conformability of bolt and predetermincd tension; Can not exist in bolt fracture in the wheel driving process, thereby the safety misadventure that causes the chain reaction of other bolt fractures to cause is therefore more safe and reliable; And cancelled bolt fastening structure, and saved the shared space of fasteners such as bolt, the size of core wheel and flange is significantly reduced, make the elastic wheel compact conformation, help making the elastic wheel in steamboat footpath; In addition, the processing capacity of core wheel and flange also reduces, and has practiced thrift cost.
