Shown in Fig. 4～6, bottom side bearing 13 adopts the bare weight two-stage friction-type structures, and it has 6 and one of a side bearing seat in the middle of being positioned at and is sleeved on also side bearing overcoat 4 moving up and down of side bearing 6 periphery.The top of seat 6 is equipped with seat briquetting 2 in the side bearing in the side bearing, and the top of seat briquetting 2 is equipped with heavily loaded friction plate 1 in the side bearing.The top of side bearing overcoat 4 is equipped with non-load friction plate 3.The elastic element 5 that is used to control both upper-lower position relations is installed between seat 6 and the side bearing overcoat 4 in side bearing, the mechanical property of elastic element 5 should make non-load friction plate 3 and heavily loaded friction plate 1 satisfy to concern as upper/lower positions: the level attitude of non-load friction plate 3 is higher than the level attitude (getting the bid and show both diff-H h in Fig. 5～6) of heavily loaded friction plate 1 under complete vehicle curb condition, and the level attitude of non-load friction plate 3 flushes with the level attitude of heavily loaded friction plate 1 under the loaded vehicle state.Simultaneously, the coefficientoffriction of non-load friction plate 3
kCoefficientoffriction with heavily loaded friction plate 1
zShould satisfy following mathematical relation: μ
k＞μ
zGenerally speaking, heavily loaded friction plate 1 can select for use High molecular material to make, and it not only has less friction coefficient, and has fabulous properties of antifriction and wear resistance, is suitable for the needs of loaded vehicle carrying; And non-load friction plate 3 can adopt the modified nylon materials in the High molecular material to make, it not only can have bigger friction coefficient, and has splendid wear-resisting erosion resistance performance, can alleviate the wearing and tearing to body side bearing 17, convenient maintenance and replacing effectively reduce use cost.
Those skilled in the art are to the diff-H h of above-mentioned elastic element 5 controls, the coefficientoffriction of non-load friction plate 3
kAnd the coefficientoffriction of heavily loaded friction plate 1
zIsoparametric choosing value scope can design or adjust by needs unloaded according to vehicle and heavy service.When reality is made, bottom side bearing 13 can adopt following two kinds of versions: the outer wall of seat 6 and the inwall of side bearing overcoat 4 are the cone barrel structure in the first side bearing, elastic element 5 be arranged between the inwall of the outer wall of seat 6 in the side bearing and side bearing overcoat 4 and with they sulfuration all-in-one-piece cone barrel rubber layers (structure among Fig. 5).Because the elasticity of shearing of cone barrel rubber layer is greater than its elasticity of compression, therefore the elastic body that is made of seat 6, side bearing overcoat 4 and elastic element 5 in the side bearing has less vertical stiffness and bigger radial rigidity, is easy to non-load friction plate 3 and heavily loaded friction plate 1 are accurately located.It two is that the outer wall of seat 6 in the side bearing and the inwall of side bearing overcoat 4 are straight tubular sliding matching structure, and elastic element 5 is arranged on the spiral retracing spring (structure among Fig. 6) between the flange of the boss of seat 6 in the side bearing and side bearing overcoat 4.The spiral retracing spring is simple in structure, handling ease, installation and replacing are convenient, is suitable for equally non-load friction plate 3 and heavily loaded friction plate 1 are accurately located.
The principle of work of bottom side bearing 13 is as follows: under complete vehicle curb condition, non-load friction plate 3 is higher than heavily loaded friction plate 1, and promptly there is diff-H h in both.This moment, body side bearing 17 only was pressed on the non-load friction plate 3, because the amount of deflection that the elastic bodys of car body composition 18 deadweight compression bottom side bearings 13 produce is less than above-mentioned diff-H h, so bottom side bearing 13 is elastic stage when empty wagons, becomes car body and form 18 tertiary system resilient suspension system.Again because the coefficientoffriction of non-load friction plate 3
kBigger, can guarantee that rail freight has higher critical speed when empty wagons.And when deadlight load increased to the loaded vehicle state, non-load friction plate 3 was pressed downward and contracts to flushing with heavily loaded friction plate 1, and promptly both diff-H h are zero.This moment, body side bearing 17 was pressed on non-load friction plate 3 and the heavily loaded friction plate 1 simultaneously, because car body composition 18 is conducted oneself with dignity and the amount of deflection of the elastic body generation of load-carrying compression bottom side bearing 13 equals even surpass above-mentioned diff-H h, so bottom side bearing 13 changes the non-yielding prop state into when loaded vehicle, most of deadlight load is born by heavily loaded friction plate 1.Because the coefficientoffriction of heavily loaded friction plate 1
zLess, can guarantee that railway freight car bogie has curving performance preferably when loaded vehicle.
