Abstract
The invention relates to accessories of railway vehicles, in particular to a bearing saddle pad, which comprises an upper board and a lower board. Tooth-shaped protrusions are respectively arranged on one surface of the upper board and one surface of the lower board, and the upper board surface with the tooth-shaped protrusions and the lower board surface with the tooth-shaped protrusions are buckled. A vulcanization layer formed by vulcanization rubber filling materials is arranged between the upper board and the lower board, and the upper board, the lower board and a section of the rubber filling materials are meshed in tooth-shaped mode. The elastic pad of the bearing saddle achieves friction-free relative moving between an auxiliary framework of a steering frame and the bearing saddle, balances top loading of the bearing saddle, achieves elastic positioning of vehicle wheel pairs, reduces moving acting force of wheel rails and improves mechanical property of vehicles.
Description
Technical field:
The present invention relates to the rolling stock accessory, particularly a kind of carrying pannel.
Background technology:
The effect of railway goods train bogie is a supporting body, and guided vehicle is along rail running, and bears the various load from car body and circuit.Bogie truck comprises that a bolster, two bogie side frames, two secondary frameworks and two wheels are right.Wherein, take turns right end and directly cooperate with the saddle face of secondary framework, two secondary frameworks connect through pipe link again, form the guide piece of bogie truck.The shortcoming that it exists is: wheel causes easily after the secondary framework abrasion that to directly assembling with secondary framework the dynamic performance of vehicle reduces, and the recovery of secondary framework can only realize that the life cycle of secondary framework is shorter by more renewing secondary framework.Simultaneously, wheel to the direct assembling of secondary framework, cause the bogie truck unsprung weight to increase the mass fraction of secondary framework, cause unsprung weight bigger than normal, the dynamic performance of vehicle is caused adverse influence.
Summary of the invention:
The problem that the present invention will solve is to above deficiency a kind of abrasion that can reduce between each parts of bogie truck to be provided, and improves the adapter cushion of vehicle dynamics performance.Its technical scheme is following:
It comprises upper plate and lower plate; In the one side of upper plate and the one side of lower plate detent projection is set respectively; The one side that upper plate and lower plate have detent projection interlocks, and the polysulphide rubbers packing material constitutes sulfuric horizon between upper plate and the lower plate, and upper plate, lower plate and rubber packing material cross section are the dentation engagement.
Compared with prior art, the beneficial effect that has of the present invention is:
1, first the gear mesh design philosophy is applied on the rubber pad class elastic element, has significantly improved the horizontal rigidity of rubber pad and the safety that product uses;
2, sulfuric horizon diagonally opposing corner position is provided with wedge shape cavity, can be through the position of adjustment wedge shape and the vertical, horizontal rigidity value that size obtains design demand, to realize optimum dynamic performance;
3, the boss of upper plate, lower plate sulfuration thin layer rubber can be realized the no gap elasticity assembling of adapter cushion and secondary framework and adapter, reduces the abrasion that relative motion causes between the free-running fit parts, improves the service life of parts;
4, the use of cushion of the present invention has realized that the no friction between secondary framework of bogie truck and the adapter relatively moves, and balanced adapter top load realizes the elasticity location that vehicle wheel is right, reduces the wheel track action firmly, improves the dynamic performance of vehicle.

The specific embodiment:
Referring to Fig. 1-Fig. 7; The present invention includes upper plate 2 and lower plate 4; In the one side of upper plate and the one side of lower plate detent projection 7 is set respectively, the one side that upper plate and lower plate have detent projection interlocks, and polysulphide rubbers packing material 6 constitutes sulfuric horizon between upper plate and the lower plate; Upper plate, lower plate and rubber packing material cross section are the shape of gear mesh, in the diagonally opposing corner position of sulfuric horizon wedge shape cavity 5 are set; Middle part in upper plate 2 and lower plate 4 has axis hole installing and locating pin 3; Locating dowel pin 3 upper ends are provided with guiding tapering 10; Axis hole aperture on the lower plate is greater than the diameter of locating dowel pin installation position, and axis hole forms interference with locating dowel pin and is connected axis hole gap polysulphide rubbers packing material; At the another side of upper plate and the another side of lower plate symmetrical boss 1 is set respectively, the boss of symmetry forms assembling and uses draw-in groove, and thin layer rubber layer 11 is vulcanized on boss 1 surface.
On lower plate 4, offer tapped bore respectively with the locating dowel pin bottom, mounting screw 9 in the tapped bore, screw 9 connects the two ends of copper conductor 8 respectively, constitutes conductive mechanism.
During use, adapter cushion 12 is positioned between secondary framework 14 and the adapter 13, reduces the abrasion between each parts of bogie truck.
