Summary of the invention
The purpose of this utility model just provide a kind of can prevent reliably that vehicle from crossing curve the time inclination, good operation stability, to cross the bend performance good; And integral structure is simple, makes the spacing railway vehicle side bearing of zero-clearance formula easy to maintenance.
The utility model solves its technical matters, the skill this programme that is adopted is: the spacing railway vehicle of a kind of zero-clearance formula side bearing, contain the side bearing assembly in side bearing box and the side bearing box, it is characterized in that: the constituting of described side bearing assembly: two inclined-planes of triangular form side bearing directly are bearing on the inclined-plane of two opposed in opposite directions triangular form voussoirs down, are provided with bilateral vulcanization steel plate rubber metal pad below these two triangle contract pieces.
Compared with prior art, the beneficial effects of the utility model are: triangle side bearing diabolo voussoir under the effect of vehicle pressure produces horizontal component of force longitudinally, two opposed in opposite directions triangle voussoirs are to two side shiftings under the effect of this component, automatically eliminate the axial clearance between triangle voussoir and side bearing box wall, make voussoir fit tightly with the vertical side of side bearing box wall all the time, improve the operation stability of vehicle thus, improved the bend performance.Bilateral vulcanization steel plate rubber metal pad then can strengthen the damping performance of car body operation; Its structure is directly to put triangle side bearing, triangle voussoir, bilateral vulcanization steel plate rubber metal pad in the side bearing box, and integral structure is simple, makes easy to maintenance.
Be connected with the side bearing wear plate on the last plane of above-mentioned triangle side bearing, the vertical side of triangle contract piece is connected with voussoir side wear plate.The setting of wear plate makes the life-span of the present utility model longer, more reliable and more stable.
Above-mentioned side bearing box also vertically is connected with a spacing side bearing box side by side, and this spacing side bearing box is built-in with a spacing roller that highly is lower than triangle side bearing upper surface.Because friction side bearing end face and spacing roller end face have a diff-H, when vehicle is crossed bend, tilting type car body is excessive to the pressure of friction side bearing, car body is depressed with spacing roller and is contacted, the motion of this contact position is the very little pure rolling of resistance, and the pressure on the triangle side bearing can not continue to increase at this moment, and friction moment can not continue to increase yet, consequently can prevent the inclination when vehicle is crossed curve reliably, can further improve the bend performance excessively of vehicle again effectively.
The arc that resets is placed in above-mentioned spacing side bearing box bottom, and spacing roller places on the arc that resets.When the car body inclination reduces, after throwing off with spacing roller, under the effect of the arc that resets, spacing roller will be returned to original position.
The upper and lower cambered surface of the above-mentioned arc that resets is a concentric circle arc plane.
The lower camber side of the above-mentioned arc that resets has a semicircle protruding stupefied, and the semi-circular recesses on this protruding stupefied and spacing side bearing box bottom cooperates.Make like this that spacing roller rolls, when resetting again behind the arc tilting that resets, arc is not shifted.
