Connect with the strengthening rib between the boss. One deck or multilayer curtain cloth suspend in the wear -resisting elastomer of software, improve the product shearing rigidity, design the strengthening rib between boss and boss, increase product stability to run through between the recess, also can provide change rigidity and be favorable to heat dissipation and drainage. The various orbital vibration/noise reduction of mainly used.
Description
Technical field
The utility model relates to the elastic shock attenuation field of track, particularly resilient sleeper-bearing under a kind of track traffic iron chair.
Background technology
Along with science and technology constantly progress, urban track traffic is rapidly developed, and the variation rigidity of the damping noise reduction of track, safe, comfortable, life-span, damping means, heat radiation, draining and cutting performance become a large technical barrier.Passenger-cargo mixed transport line road becomes trend now, requires that Damping fastening system has variable rigidity property, higher shearing rigidity.Be applied under iron chair on resilient sleeper-bearing by rail and all the other fasteners during passenger-cargo mixed transport line road train operation, under making iron chair, resilient sleeper-bearing is stressed more complicated, reduces the application life of resilient sleeper-bearing under iron chair simultaneously.
Under existing iron chair, resilient sleeper-bearing is mostly pure elastic body, when train operation, under train acts on iron chair by rail and connection fastener, resilient sleeper-bearing power comprises longitudinal force, lateral force and bend place twisting resistance, causes distortional elastomer complicated, reduces the life-span of resilient sleeper-bearing.
Prior art and technical problem have:
1) resilient sleeper-bearing under cone boss formula iron chair: a kind of two work planes design cone bosses pure elastomeric iron chair under resilient sleeper-bearing, heat radiation, draining and variation rigidity problem can be solved; Resilient sleeper-bearing under cone boss formula iron chair: cutting performance is poor, easily causes shear deformation breaks down;
2) resilient sleeper-bearing under the iron chair of new material: resilient sleeper-bearing under the pure elastomeric iron chair adopting the new materials such as polyurethane to produce.Resilient sleeper-bearing under the iron chair of new material: complex forming technology, material unit price are expensive.
Utility model content
The purpose of this utility model in order to overcome existing pure elastomer structure iron chair under the little shortcoming of resilient sleeper-bearing shearing rigidity, provide one to realize variation rigidity, resilient sleeper-bearing under the iron chair of high shear rigidity can be provided again.
The purpose of this utility model is achieved through the following technical solutions: resilient sleeper-bearing under a kind of iron chair, comprise elastic body and cord, described resilient sleeper-bearing is provided with mounting-positioning holes, and cord is arranged in the elastomer, and there are polygonal grooves and round boss in described elastic body one side.Connect with reinforcing rib between boss.
Further, elastomeric material is software high-abrasive material, and cord is woven by crisscross cord and forms, and cord thickness range is 0.8 ~ 1mm.
Further, elastic body and cord are by adhesive, and high temperature, high pressure sulfide.
Further, in elastic body, some layers of cord can be set.
Resilient sleeper-bearing is provided with mounting-positioning holes for installing screw spike, resilient sleeper-bearing and all the other fastener component under iron chair are fixed on railway roadbed.Cord is woven by crisscross cord and forms.Because cord gauge is little, therefore increase cord structure, vertical to resilient sleeper-bearing under iron chair, namely with rail axes normal, stiffness effect is straight down very little, but can increase substantially shearing rigidity.
Resilient sleeper-bearing under iron chair provided by the utility model, when bearing load, distortion mainly concentrates on the elastic body of lower convex platform layer, when load is increased to a certain degree, the contact area of bearing surface increases suddenly, the vertical stiffness of the lower resilient sleeper-bearing of iron chair increases thereupon, realizes variable rigidity property, the vibration and noise reducing requirement of (axle weight) under meeting different loads.
The beneficial effects of the utility model are:
Under this iron chair, resilient sleeper-bearing adds polygonal grooves, can realize variation rigidity; Inside adds cord, can improve product shearing rigidity.
1, one or more layers cord is suspended in software wear-resistant elastomeric, improves product shearing rigidity.
2, between boss and boss, design reinforcing rib, increase product stability, and run through between groove, variation rigidity also can be provided and be conducive to heat radiation and draining.
accompanying drawing illustrates:
Fig. 1 is top view of the present utility model;
Fig. 2 is that the A-A of the utility model Fig. 1 cuts open front view;
In figure: 1-groove; 2-mounting-positioning holes; 3-reinforcing rib; 4-elastic body; 5-cord.
Detailed description of the invention
Below in conjunction with attached Example, resilient sleeper-bearing under the utility model iron chair is further described.
As shown in the figure, resilient sleeper-bearing under a kind of iron chair of the utility model, comprise software wear-resistant elastomeric 4 and one deck cord 5 two parts, cord is arranged in software wear-resistant elastomeric, polygonal grooves 1 and round boss is had in software wear-resistant elastomeric one side, connect with reinforcing rib 3 between boss, mounting-positioning holes 2 resilient sleeper-bearing and all the other fastener component under installing screw spike to make iron chair are fixed on railway roadbed.
Under utility model iron chair resilient sleeper-bearing resilient sleeper-bearing under pure software wear-resistant elastomeric iron chair basis on design increase cord 5 and polygonal grooves 1, cord 5 thickness is 0.8mm, this design not only increases shearing rigidity, and can realize stiffness changing structure feature.
Under utility model iron chair, resilient sleeper-bearing is software wear-resistant elastomeric 4 is all by adhesive with cord 5, and high temperature, high pressure sulfide.
Under iron chair provided by the utility model, resilient sleeper-bearing is the parts mainly providing elastic stiffness in fastener system.During installation, without groove surface upward, flutedly to face down, be arranged in the middle of iron chair and cement sleeper by mounting-positioning holes screw spike, by the shearing of software wear-resistant elastomeric or compress the stressed elasticity providing track.
With cord in this utility model structure, very little on vertical stiffness impact while raising lateral stiffness, increase the reliability of train operation.
