Abstract
The invention discloses an integrated wheel of a broad-track internal combustion locomotive. The integrated wheel comprises a wheel hub, a wheel rim and a wheel disk for connecting the wheel hub with the wheel rim, wherein the diameter of the outer edge of the wheel rim contacting a track is 1080-1083 mm; the thickness of the wheel rim is 74.5-77 mm; and the width of the wheel rim is 140-143 mm. According to the integrated wheel, the diameter of the outer edge of the wheel rim contacting the track meets the bottom limitation requirement of the broad-track internal combustion locomotive, the thickness of the wheel rim guarantees the all-wear size range of the wheel, and the width of the wheel rim guarantees the normal contact of the wheel and the track, so that the broad-track internal combustion locomotive runs safely on the track.
Description
Technical field
The present invention relates to diesel locomotive technology, particularly relate to a kind of broad gauge diesel locomotive solid wheel.
Background technology
One of right critical component taken turns by wheel, but wheel is to being again the vitals being directly connected to traffic safety in rolling stock running part simultaneously, subjects huge static weight and live load.On the one hand, the weight that locomotive is whole eventually through wheel support on rail; On the other hand, the tractive force that locomotive is whole and braking force are also finally the friction force derived between rail and wheel tread; Moreover locomotive will be advanced along rail all the time, its guiding and safeguard function must be played by the wheel rim of wheel, take turns and the operation of rolling stock on rail is achieved to rotation.Diameter (external profile diameter of the finger wheel rim contact track) specification that standard gauge wheel is conventional in the world at present has: Φ 840mm, Φ 890mm, Φ 915mm, Φ 1050mm, Φ 1250mm.Vehicle Φ 840mm, the Φ 890mm such as usual motor-car, subway, lorry, passenger vehicle, Φ 915mm wheel are more, and diesel locomotive Φ 1050mm wheel is more, and use for electric locomotive Φ 1250mm wheel is more, but and are not exclusively confined to this.
Current diesel locomotive diameter with the most use is the car wheel structure of Φ 1050mm, and have assembled vehicle wheel, also have solid wheel, the thickness of wheel rim is not less than 70mm usually, and the width of wheel rim is usually between 139mm ~ 145mm.But for using the country of broad gauge (rail spacing is 1520mm), because broad guage line gauge is different from standard gauge (rail spacing is 1435mm) circuit gauge, and the impact of other factors such as traction motor suspension system, the lower that train wheel axletree is installed will maintain a certain distance between track and wheel contact surface, guarantee locomotive safety in the process of moving, this distance is called boundary bottom locomotive, adopts the wheel of Φ 1050mm can not meet the bottom gauge requirement of broad gauge locomotive.
Summary of the invention
The invention provides a kind of broad gauge diesel locomotive solid wheel, for overcoming defect of the prior art, in wheel complete wear consumption range of sizes, to meet bottom locomotive the requirements such as gauge.
Broad gauge diesel locomotive solid wheel provided by the invention, this wheel is made up of the disc of wheel hub, wheel rim and connection wheel hub and wheel rim, the external profile diameter of described wheel rim contact track is between 1080mm ~ 1083mm, the thickness of described wheel rim is more than or equal to 74.5mm, and the width of wheel rim is between 140mm ~ 143mm.
Broad gauge diesel locomotive solid wheel provided by the invention, the external profile diameter scope of wheel rim contact track meets gauge requirement bottom broad gauge locomotive, the thickness range of wheel rim ensure that the complete wear consumption range of sizes of wheel, the width of wheel rim ensure that wheel contacts with the normal of track, makes locomotive safe operation in orbit.
Accompanying drawing explanation
Fig. 1 is the front view of solid wheel provided by the invention;
Fig. 2 be in Fig. 1 along A-A to cutaway view.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of broad gauge diesel locomotive solid wheel, this wheel is by wheel hub 1, wheel rim 2 and be connected wheel hub 1 and form with the disc 3 of wheel rim 2, wheel rim 2 contacts the outer rim 21 diameter D of track between 1080mm ~ 1083mm, the thickness d of wheel rim 2 is more than or equal to 74.5mm, and the width L of wheel rim 2 is between 140mm ~ 143mm.
Broad gauge diesel locomotive solid wheel provided by the invention, material meets the regulation of T steel in standard GOST10791-2011, tread 22 i.e. wheel rim radial edges profile meets " locomotive tread contour profile " requirement in GOST11018-2000, and wheel diameter complete wear consumes limit diameter D
1for 1000mm, outer rim 21 diameter range that wheel rim 2 contacts track can meet gauge requirement bottom broad gauge locomotive, the thickness range of wheel rim 2 ensure that wheel can reach complete wear consumption range of sizes and ensure that wheel damages in complete wear the minimum thickness value reaching requirement of strength in range of sizes, the width L of wheel rim 2 ensure that wheel contacts with the normal of track, makes locomotive safe operation in orbit.As the preferred implementation of the present embodiment, the thickness d of wheel rim, between 74.5mm ~ 77mm, both ensure that the requirement of strength in wheel complete wear consumption range of sizes, and can not cause again increasing extra load because wheel is overweight.
In order to facilitate the dismounting of wheel in maintenance process, wheel hub 1 is provided with oil hole 4, wheel hub 1 inner hole surface is provided with ring-type oil guide groove 5, and oil hole 4 is communicated with ring-type oil guide groove 5.Outer end 41 opening opposing inner end 42 opening of oil hole 4 is larger, and be provided with the negative thread suitable with lubricating cup outside thread in outer end 41, during concrete use, can by also oiling wherein in direct for lubricating cup precession oil hole 4, oil enters in ring-type oil guide groove 5, at this moment impact wheel and it is disassembled from axletree, because there being oil lubrication just more laborsaving between wheelboss inner hole 11 with the axletree be through in this endoporus 11.
As the detailed description of the invention of above-described embodiment, the angle ∮ between oil hole 4 line of centers and wheel center line, between 50 degree ~ 60 degree, is preferably 57 degree, refuels convenient.Angle ∮ between the vertical plane of disc 3 and wheel hub 1 line of centers
1it is 20 degree.The wherein thickness of disc radially gradual change, disc 3 is near the maximum ga(u)ge d of wheel hub
1between 46mm ~ 47mm, disc is near the minimum thickness d of rim
2between 27.5mm ~ 28.5mm, when keeping solid wheel weight, meet the loading strength of solid wheel.As required, disc 3 also evenly can arrange auxiliary hole, assembling can be checked convenient wheel on the one hand, wheel weight can be alleviated on the other hand.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
