Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of motor train unit wheel that the utility model provides is described in detail.
In the following description, for those skilled in the art, can only utilize some or all structure of the present utility model or flow process to implement the utility model.In order to the definition explained, set forth specific number, configuration and order, but clearly, also can implement the utility model when there is no these specific detail.In other cases, in order to not obscure the utility model, will no longer be described in detail for some well-known features.
Motor train unit wheel of the present utility model is overall wrought steel wheel, is made up of 3 main region, i.e. wheel hub 1, disc 2, wheel rim 3, and wherein disc 2 is arranged between wheel hub 1 and wheel rim 3, and each region particular location as shown in Figure 1.
Wheel data of the present utility model is illustrated below according to Fig. 2.
(1) tread rolling circle diameter and wheel rim effectively wear away thickness
" 1.2Wheeldiameter " with reference to the standard UIC510-2-2004 of this area is known, and when new wheel tread rolling circle diameter is 920mm, the minimum tread rolling circle diameter that abrasion allow to limit state is 840mm.According to the regulation of 5.1.27 in this area standard TJ/CL342-2014 " the provisional engineering factor of speed per hour 350km Chinese Industrial Standards (CIS) motor train unit ", new wheel tread rolling circle diameter is 920mm, the tread rolling circle diameter that full abrasion state is corresponding is 850mm, and therefore this numerical value of response of the application meets the regulation of standard UIC510-2-2004.
According to the regulation of this area standard TJ/CL342-2014, wheel is not less than 2,400,000 kilometers service life, motor train unit are about between 1.9mm ~ 2.5mm in the tread wear amount that utilization 1,000,000 km is corresponding, Xuan repaiies number of times between 4 times ~ 5 times, comprise tread wear and tread Xuan repair after tread attrition inventory quantity between 4mm ~ 6mm.Consider the factors such as vehicle eccentric wear, reserved wheel rim adds Xuan and measures 9mm, then the corresponding tread Xuan of 1,000,000 km repaiies and is worth about 15mm, it is 35mm that wheel rim effectively wears away thickness, 2000000 kilometers of Xuan repair rear rim and still retain 5mm and effectively wear away thickness, be enough to support wheel and use 400,000 kilometers, therefore wheel meets 2,400,000 kilometers of requirements service life.
(2) abrasion are to the wheel rim residual thickness of limit correspondence
According to the regulation of " railway carriage wheel is assembled and the regulation of inspection and repair with roller-bearing axle box ", the wheel rim thickness limit value that the above passenger vehicle of speed per hour 120km is corresponding when auxiliary (A1) repaiies and use is 25mm, with reference to this assembling and the regulation of inspection and repair, wheel wear is decided to be 25mm to wheel rim residual thickness of prescribing a time limit by the utility model, and corresponding wheel rim internal diameter is 800mm.
(3) wheel hub aperture, hub thickness and hub width
According to Chinese Industrial Standards (CIS) axle of motor train unit drawing, motor vehicle wheels hub bore diameter is 200mm.
Hub thickness size has influence on wheel shaft tautness, and for ensureing wheel shaft tautness, wheel hub wall thickness is enough large, but in order to reduce wheel mass, wheel hub wall thickness should be little as far as possible.The non-powered wheel of reference CRH380A (L) motor train unit wheel and CRH380B (L) motor train unit, is set as 30mm by wheel hub wall thickness.
According to the regulation of standard technological document TJ/CL281-2013 " motor train unit wheel is to composition (provisional) ", hub width should between 0.85dm ~ 1.1dm (dm is wheel seat diameter), the hub width of reference CRH380A (L) motor train unit wheel and CRH380B (L) motor train unit wheel, finally determines that wheel nave width is 175mm simultaneously.
(4) inner side hub rim distance
Using for reference the hub rim of CRH380A (L) motor train unit wheel and CRH380B (L) motor train unit wheel apart from also considering to optimize on wheel seat place relief groove architecture basics, determining that inner side hub rim is apart from being 15mm.
(5) disc shape
Chinese Industrial Standards (CIS) motor train unit power wheel, to employing Multiple disc brake, adopts straight wheel plate structure in conjunction with brake mode dynamic wheel.
(6) rim width, flange tread external form
With reference to the relative dimensions of existing motor train unit wheel, rim width is determined 135mm; Flange tread profile is one of most basic part of wheel, it must with rail head of rail mating shapes.It with line condition, vehicle performance is relevant, and very little with wheel web structural relation.According to this area standard TJ/CL342-2014 requirement, wheel rim tread profile is LMA or S1002CN.
(7) structural strength
Application UIC510-5-2007 " TechnicalApprovalofMonoblocWheels " is checked structural strength of the present utility model, the check result of static strength is in table 1 and Fig. 3, the safety factor minimum value of static strength is 1.37, the check result of strength at repeated alternation is shown in Fig. 4, the safety factor of strength at repeated alternation is 360/272.9=1.32, pi of strength of the present utility model meets the relevant regulations of UIC510-5-2007, and has higher-strength allowance.
