The utility model has the advantages that:
1. the utility model discloses well cushion adopts metal and the metal rubber pad that rubber vulcanization combines to form, and when bearing the heavy load, the rigidity of cushion is bigger, and the adhesive force between metal and the rubber can slow down the mobile speed of bulging when rubber warp, reduces the deflection of rubber, avoids rubber to bulge too much and can't recover from the steel spring support, reduces the permanent deformation probability of cushion, prolongs the life of cushion.
2. The cushion is fixed bottom steel spring support, aligns and unset with the axle box is coaxial, is convenient for lift by crane steel spring support and cushion simultaneously, adds pad gasket regulation axle box height between cushion and axle box, axle box altitude mixture control labour saving and time saving.
3. The elastic cushion comprises a metal layer and a rubber layer, the metal layer is in contact with the steel spring support, and the rubber layer is in contact with the axle box, so that the insulating effect of the elastic cushion on the axle box is guaranteed.

Detailed Description
The following describes embodiments of the present invention in detail with reference to fig. 1 to 2.
Axle box suspension, including steel spring support 1 that installs steel spring and coaxial setting at the axle box 2 of steel spring support 1 below and cushion 3 at the metal rubber pad that axle box 2 and steel spring support 1 between its characterized in that elastic pad 3 combine the metal rubber pad that forms for metal and rubber vulcanization, elastic pad 3 is fixed with 1 bottom of steel spring support, with 2 coaxial alignments of axle box and unfixed.
As shown in the figure, the elastic pad 3 in the axle box suspension device adopts a metal rubber pad formed by combining metal and rubber in a vulcanization mode, when a large load is borne, the rigidity of the elastic pad is larger, the flowing bulging speed of the rubber during deformation can be reduced by the binding force between the metal and the rubber, the deformation of the rubber is reduced, the rubber is prevented from bulging too much from a steel spring support and being incapable of being restored, the permanent deformation probability of the elastic pad is reduced, and the service life of the elastic pad is prolonged. 3 steel spring supports 1 of cushion are fixed, and with 2 coaxial alignments of axle box and unset, be convenient for lift by crane steel spring support and cushion simultaneously, add pad gasket regulation axle box height between cushion and axle box, axle box altitude mixture control labour saving and time saving.
Wherein, cushion 3 fixed with 1 interference fit of steel spring support, with 2 clearance fit of axle box, clearance fit can realize axle box and cushion 3's coaxial alignment, make axle box 2 unfixed with cushion 3 again, be convenient for with lifting by crane cushion 3 and steel spring support 1.
The elastic pad 3 is inverted T-shaped, the bottom of the copper spring support 1 is provided with a connecting cylinder cavity 11 for the axle box 2 and the elastic pad 2 to extend into, the elastic pad 3 extends into the connecting cylinder cavity 11 to be in interference fit with the inner wall of the connecting cylinder cavity 11, and the elastic pad and the axle box 2 extend into the partial clearance fit of the connecting cylinder cavity 11. As can be seen from fig. 1, the upper portion of the elastic pad 3 extends into the connecting cylinder chamber 1, is in interference fit with the cylinder wall of the connecting cylinder chamber 11, and is in clearance fit with the portion of the axle housing 2 extending into the connecting cylinder chamber 11, and the elastic pad 3 is in radial abutting contact with the axle housing 2 and is in clearance fit with the axle housing 2 in axial direction.
The elastic pad 3 comprises a metal layer 31 and a rubber layer 32, wherein the metal layer 31 is in contact with the steel spring support 1, and the rubber layer 32 is in contact with the axle box 2. The metal layer 31 is in contact with the steel spring support 1, the metal layer 31 is in close contact with the steel spring support 1 along the radial direction and is in interference fit with the steel spring support 1 along the axial direction, and the rubber layer 32 is in contact with the axle box 32 to keep the elastic cushion 3 in insulating action on the axial direction 2.
Wherein, the top surface of the part of the elastic cushion 3 extending into the connecting cylinder cavity 11 is axially separated from the top wall of the connecting cylinder cavity 11 by a distance larger than the thickness of the rubber layer 32. The steel spring support 1 and the metal layer 31 are ensured not to collide in the compression process of the rubber layer 32.
