Abstract
The utility model discloses a lubricated wheel flange and a tread used for railway vehicles. The tread adopts a wear type tread, namely a cambered surface having a concave middle and matched with the top of a rail; and the contact surface between the wheel flange and the rail adopts a concave arc surface matched with the side surface of the rail. A lubrication mechanism is arranged at the contact part of the wheel flange. The lubricated wheel flange and the tread have the outstanding characteristics that by adopting the design method of the wear type tread, the shape of the tread is well matched with the top of the rail, and the tread is used for mainly loading the vertical and longitudinal load of vehicles; the concave arc surface arranged at the wheel flange position ensures that the wheel flange is well matched with the side surface of the rail, and the wheel flange is used for mainly loading the transverse load of vehicles when the vehicles pass through the wheel flange in a curved way, and the contact part of the wheel flange is lubricated to effectively reduce the abrasion wear between the wheel flange and the side surface of the rail, prolong the service life of the wheel flange, improve the adhesion utilization of the wheel rail, and simultaneously reduce the noise of the wheel rail and the derail risk.
Description
Technical field
The utility model belongs to the guideway vehicle technical field, relates in particular to used for rail vehicle flange tread configuration design technology.
Background technology
On the railway line, vehicle is subjected to the influence of centnifugal force when the curve, and vehicle wheel is to producing cross travel, causes the wheel rim rail that reclines, and the side grinding problem of the abrasion of wheel rim and curved steel rail is very serious.At the serious section of situation, tens thousand of kilometers wheel rims of locomotive running gear just wear away limit, and rail just needed to upgrade in per two, three years, may cause the derail accident to take place when serious.It is curve that there is 1/3rd railway in China.
The wheel tread shape of early stage railway is the taper tread, the tread middle part is made of the straight line of two sections Different Slope, its shortcoming has: at wheel to being subjected to transverse force or when the curve, be 2 contact conditions (as shown in Figure 3, Figure 4) between wheel and the rail, have at least in two contact points a bit and slide, very unfavorable to wheeling edge wearing; Tread middle part shape does not match with the shape of rail's end portion, and particularly inconsistent with the later rail shape of abrasion, the tread middle part at utilization initial stage wears away bigger.Therefore, the design of taper tread progressively is worn away shape tread design replacement.
The method of designing of worn profiled wheel tread is that the tread middle part is designed to spill, generally is made of plurality of sections circular arc or discrete point, and its advantage is: there is coupling preferably at the tread middle part with the rail tread, reduces the wheel track tread wear; When reclining rail, wheel rim avoided 2 contacts (as Fig. 5, shown in Figure 6).Its shortcoming is: wheel-rail force was still bigger when wheel rim reclined rail, and wheel rim and rail side wear are still relatively more serious.
At present, rim lubricating device is widely used in countries in the world, has played certain wheel rim and trackside attrition of slowing down, and has obtained good economic effects.But for worn profiled wheel tread, when wheel rim reclined rail, wheel flange lubricating had reduced the wheel-rail friction power of this position, can have influence on the wheel rail adhesion utilization.
Summary of the invention
The purpose of this utility model is that design is a kind of on the basis of Wheel Rail Lubricating Technology, and the flange tread with the functional separation of the wheel rim of wheel and tread makes the tread part mainly bear the vertical and longitudinal load of wheel, and lateral load is mainly born at the wheel rim position.
The technical solution of the utility model is: lubricating type flange tread for railway vehicle, comprise tread and wheel rim, and wheel rim and rail contact site are provided with lubricating structure, it is characterized in that described tread is a worn profiled wheel tread, i.e. the recessed cambered surface that matches with the rail tread in middle part; The concaved circular cambered surface of described wheel rim for matching with the rail side compared with the wheel rim arc length of convex arc surface, and the wheel rim arc length of concaved circular cambered surface is long relatively, and the contact surface of concaved circular cambered surface and rail and horizontal angle are at 60 °--between 80 °.
Outstanding feature of the present utility model is; Have wide range of applications, locomotive, vehicle, city railway vehicle etc. can be used; Adopt the method for designing of worn profiled wheel tread, tread contour is had preferably with the rail tread cooperate; At the wheel rim position is concave arc (as shown in Figure 2), wheel rim is had preferably with the rail side cooperate, and the wheel rim contact site is lubricated, can effectively alleviate the abrasion of wheel rim and trackside, prolong wheel track service life, improve the wheel rail adhesion utilization, reduce wheel-rail noise simultaneously and derailing is dangerous.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 7 is the design drawing of lubricating type flange tread embodiment.The outside beginning of wheel tread part trailing wheel is successively by the two sections straight lines and radius R 450 circular arcs 3 of 1: 15 straight line 1,1: 40 straight line 2, R85 circular arc 4, and R18 circular arc 5 connects and composes.Rim section is made of the concave arc 6 of R14 and the dome arc 7 of R16.Wherein wheel rim R14 concave arc 6 has replaced design-calculated dome arc in the past, arc length extends relatively, and the contact surface of rail and the angle of level are at 60 °--between 80 °, and for rim lubricating device is smeared or the special-purpose position of jet lubrication medium, purpose is that wheel rim is when reclining rail, increase the area of wheel rim and trackside contact surface, reduce contact stress, slow down wheel-rail wear from structure and lubricated two aspects.
