Abstract
The invention discloses an elastic wheel which comprises a wheel core, a wheel rim, an upper clamping ring and a lower clamping ring, wherein the upper clamping ring and the lower clamping ring are buckled on the inner side of the wheel rim; the two clamping rings are connected through fasteners; the inner circumferential surface of the wheel rim concaves inwards in the radial direction so as to form a conical convex surface of which the cross section is corn-shaped; a baffle side is formed in the edge of the inner circumferential side of the wheel rim; the outer circumferential surface of the two upper and lower overlapped clamping rings concaves inwards in the radial direction so as to form a conical concave surface of which the cross section is corn-shaped; the conical concave surface is matched with the conical convex surface; metal wire elastic bodies are sandwiched between the conical concave surface and the conical convex surface. The elastic wheel has the beneficial effects that due to adoption of the elastic bodies woven from metal wires, the wheel has elasticity and damping characteristics, and is high in durability, not easy to be invalid and low in maintenance expense, and the security is improved while the vibration of a wheel track is partitioned and the impact and the noise of the wheel track are reduced.
Description
Technical field
The present invention relates to a kind of wagon wheel, belong to railway truck field.
Background technology
At present along with the development of railway transportation, speed and the load-carrying of railway truck all constantly increase, and wheel-rail impact and noise problem more and more come into one's own, and also put into effect Its Relevant Technology Standards already abroad, limit the noise of railway truck.
Wheel is the critical component of railway truck, is directly connected to wheel-rail impact and noise.Traditional wheel has solid wheel and split wheel two kinds, and wherein split wheel has again the elastic wheel of all-metal wheel and embedded rubber element.Solid wheel and all-metal split wheel all belong to unsprung weight, and owing to not having shock absorber between axletree, its quality is larger, impulsive force and noise larger.Rubber elastic wheels has inlayed rubber bodies between core wheel and rim, and have positive effect to shock absorbing and reduction noise, but the rigidity of rubber is little, cause rim to bear drawingand pressing fatigue load for a long time, safety is low; Meanwhile, rubber is easily aging under high temperature, low temperature, and easy cracking failure reduce further wheel safety.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of elastic wheel, there is large, the durable good feature of rigidity, reduce wheel-rail impact and noise, and safety is high.
The present invention is achieved by the following measures:
A kind of elastic wheel of the present invention, comprises upper and lower inside rim of core wheel, rim and spiral-lock
Two snap rings, two snap rings are connected by fastener, the inner peripheral surface of described rim radially-inwardly protrudes into the cone convex surface that cross-sectional plane is taper, and the inner peripheral surface edge of rim is provided with rib, the outer circumference surface of two snap rings superposed up and down radially-inwardly caves in has cross-sectional plane to be the cone concave surface of taper, described cone concave surface interlocks assemble close with cone convex surface, and bores concave surface and bore between convex surface and accompany wire elastic body.
The outer circumference surface centre circle of above-mentioned core wheel radially outward protrudes, and projection extreme circumferential face coordinates with the inner periphery conical surface spiral-lock of two snap rings.
The outer circumference surface centre circle of above-mentioned core wheel radially outward protrudes, and projection to be clipped between upper and lower two snap rings and to be connected by fastener.
Above-mentioned wire elastic body is Stagger-wrap metal filament together, and described metal filament adopts cross-sectional plane to be circular carbon steel wire, stainless steel wire or spring wire, and diameter wiry is less than or equal to 0.5mm.
The invention has the beneficial effects as follows: wheel adopts the elastic body of metal wire knitted, has elasticity, damping force characteristics, elastic wheel is while isolation Wheel Rail Vibration, reduction wheel-rail impact power and noise, safety is improved, and durability is strong, not easily lost efficacy, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the embodiment of another structure of the present invention.
Wherein, 1. rim, 2. elastic body, 3. core wheel, 4. snap ring, 5. fastener.
Detailed description of the invention
Below in conjunction with accompanying drawing, further detailed description is done to the present invention:
Embodiment 1: a kind of elastic wheel of the present invention as shown in Figure 1, 2, comprise core wheel 3, rim 1 and spiral-lock two snap rings 4 up and down inside rim 1, the inner peripheral surface of rim 1 radially-inwardly protrudes into the cone convex surface that cross-sectional plane is taper, and the inner peripheral surface edge of rim 1 is provided with rib, the outer circumference surface of two snap rings 4 superposed up and down radially-inwardly caves in has cross-sectional plane to be the cone concave surface of taper, cone concave surface interlocks assemble close with cone convex surface, and bores concave surface and bore between convex surface and accompany wire elastic body 2.The outer circumference surface centre circle of core wheel 3 radially outward protrudes, and projection extreme circumferential face coordinates with the inner periphery conical surface spiral-lock of two snap rings 4.Upper and lower two snap rings 4 are connected by the fastener 5 of countersunk head structure.The periphery of mutual spiral-lock adopts taper, makes each parts stressed more even, improves the stability of spiral-lock.The displacement laterally of rib restriction elastic body 2.Wire elastic body 2 is Stagger-wrap metal filament together, and metal filament adopts cross-sectional plane to be circular carbon steel wire, stainless steel wire or spring wire, and diameter wiry is less than or equal to 0.5mm.Wire elastic body 2 has elasticity and damping force characteristics, and because matrix is metal, its good endurance, when bearing load, compression stiffness is large.By metal wire knitted elastic body 2, elastic wheel is while isolation Wheel Rail Vibration, reduction wheel-rail impact power and noise, and safety is improved.
Embodiment 2, as shown in Figure 3, the outer circumference surface centre circle of core wheel 3 radially outward protrudes, and projection to be clipped between upper and lower two snap rings 4 and to be connected by fastener 5.Other is identical with embodiment 1.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
