Abstract

The utility model discloses an elastic wheel, comprising a tire with a center hole, and a wheel center component, wherein the wheel center component is located in the center hole of the tire; moreover, a clearance S is kept between the wheel center component and the tire. The wheel center component comprises a flange, a fastening piece and a wheel center with a hub hole, wherein the wheel center is fixedly connected with the flange by the fastening piece, and further provided with a plurality of elastic elements; and the elastic elements are located between the wheel center component and the tire, and further evenly distributed along the circumferential direction of the inner wall of the center hole of the tire. For the elastic wheel, the elastic elements are small in volume, convenient in production, low in production cost and long in service life.

Description

A kind of elastic wheel

Technical field

The utility model relates to a kind of elastic wheel, specifically be a kind of elastic wheel of rail traffic vehicles.

Background technology

In the last few years, development such as urban track traffic subway and light rail was rapid, and traditional subway and light rail vehicle still adopt the traditional rigid wheel mostly, and this wheel noise emission in motion is serious, and railway resident living along the line is caused very big influence.At present, the elastic wheel of domestic production mainly is to press to cut the composite elastic wheel, and the elastic element of this type wheel is symmetrical ring-type rubber ring; Volume is bigger, and production technology is difficult to control, and productive costs is high; Simultaneously since its each section density refractory to grasp, the general life-span is lower in the process of using.

Summary of the invention

The purpose of the utility model is to provide a kind of elastic element volume little, is convenient to produce, and reduces production costs, and improves the elastic wheel in service life.

The technical scheme that realizes above-mentioned purpose is: a kind of elastic wheel, comprise rim and core wheel assembly with centre hole, and the core wheel assembly is positioned at the centre hole of rim; And has gap S between core wheel assembly and the rim; The core wheel assembly comprises flange, fastener and has the core wheel of hub bore that core wheel is captiveed joint with flange through fastener, also has several elastic elements; Elastic element and circumferentially is uniformly distributed with along the center bore inner wall of rim between core wheel assembly and rim.

Common looping cavity volume between said core wheel assembly and the rim, said several elastic elements are evenly arranged in the ring-shaped chamber, and the cross-sectional plane of ring-shaped chamber is V-shaped, and the cross-sectional plane of elastic element is also V-shaped.

The hole wall middle part of the centre hole of said rim has radial ringed convexity, and the elastic element middle part has the position-limited trough that is complementary with annular protrusion, and annular protrusion is inserted in the position-limited trough of elastic element.

The quantity of said elastic element is 6 ~ 18.

The quantity of said elastic element is preferably 12.

After adopting the structure of technique scheme,, combine and can play cushioning effect equally,, be convenient to produce, be easy to moulding, greatly reduce cost so the volume of elastic element dwindled more greatly because the utility model has adopted several elastic elements; Simultaneously because the elastic element volume is little; In the process of production and processing, guarantee the single-piece thickness easily; Density evenly, making elastic element in the process that reality is used, can prolong its service life can increase the stability of elastic wheel damping effect simultaneously, and is convenient to installation and removal.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.

Referring to 1,2,3,4,5,6, shown in 7; A kind of elastic wheel comprises rim 1 and core wheel assembly 2 with centre hole 1-1, and core wheel assembly 2 is positioned at the centre hole 1-1 of rim 1; And has gap S between core wheel assembly 2 and the rim 1; Core wheel assembly 2 comprises flange 2-1, fastener 2-2 and has the core wheel 2-3 of hub bore 2-3-1 that core wheel 2-3 is captiveed joint with flange 2-1 through fastener 2-2, also has several elastic elements 3; Elastic element 3 and circumferentially is uniformly distributed with along the centre hole 1-1 inwall of rim 1 between core wheel assembly 2 and rim 1.

Referring to 2,3, shown in 7, common looping cavity volume 4 between said core wheel assembly 2 and the rim 1, said several elastic elements 3 are evenly arranged in the ring-shaped chamber 4, and the cross-sectional plane of ring-shaped chamber 4 is V-shaped, and the cross-sectional plane of elastic element 3 is also V-shaped; V-shaped structure can axially with radially produce rigidity simultaneously, simultaneously, along with the change of v shape angle can regulate wheel axially with the radial rigidity distribution, satisfy different performance needs.

Referring to 1,2,3,4, shown in 7; In order to make several elastic elements 3 stable position when installing and use; The hole wall middle part of the centre hole 1-1 of said rim 1 has radial ringed protruding 1-1-1; Elastic element 3 middle parts have the position-limited trough 3-1 that is complementary with annular protrusion 1-1-1, and annular protrusion 1-1-1 is inserted in the position-limited trough 3-1 of elastic element 3.

Shown in 3, in order to satisfy actual needs, said elastic element 3 is rubber blocks, and the quantity of said elastic element 3 is 6 ~ 18, and the quantity of elastic element 3 is preferably 12.Can certainly suitably add and reduce elastic element 3 according to the size of rim 1.

Referring to shown in Figure 1, when the utility model is installed and used, core wheel 2-3 is captiveed joint with flange 2-1 through fastener 2-2; And core wheel assembly 2 is positioned at the centre hole 1-1 of rim 1; Have gap S between the two, as the damping, buffering distance, 12 elastic elements 3 are installed in the ring-shaped chamber 4; And the radial ringed protruding 1-1-1 location on the hole wall of the centre hole 1-1 through rim 1, make 12 elastic elements 3 can install accurately.

Elastic element 3 can be processed by elastomeric material, can also in elastomeric material, add framework materials such as fiber, spring wire, to increase the intensity of elastic element 3, perhaps processes for composite material.Fastener 2-2 comprises bolt, nut.
