The utility model discloses good, non-deformable, not hard up of grabbing to friction material can guarantee braking effect, and joint strength is high, the bearing capacity is big, can improve production efficiency.
Description
Technical Field
The utility model relates to a brake shoe steel backing for locomotive.
Background
The brake shoe steel back of the locomotive is arranged on a locomotive shoe support of a braking system and needs to bear larger load; the brake shoe steel back of the existing railway locomotive comprises an arc-shaped steel back body, a shoe nose arranged in the middle of the steel back body, two positioning plates arranged on two sides of the shoe nose and a material grabbing hole, wherein the shoe nose is a bending plate and is provided with a through pin hole and is riveted with the steel back body; the tile nose is fixedly connected to the tile support through a penetrating pin, and a synthetic friction material is laid on one side of the inner arc surface of the steel back body and in the plurality of material grabbing holes, so that the friction coefficient and the braking effect are improved; but the grip of the shoe steel back to the friction material is not good, and in addition, the friction material is easy to be heated, deformed and loosened, the braking effect is affected, normal work is difficult to ensure, the connection strength of the shoe nose and the steel back body is low, the installation is inconvenient, the bearing capacity is low, and the production efficiency is also reduced.
Disclosure of Invention
The utility model aims at the above-mentioned not enough that prior art exists, provide a brake shoe steel backing of locomotive, it is good, non-deformable, not hard up to friction material's the grip ability, can guarantee braking effect, and joint strength is high, the bearing capacity is big, can improve production efficiency.
In order to achieve the purpose, the brake shoe steel back of the locomotive comprises an arc-shaped steel back body, a shoe nose arranged in the middle of the steel back body, two positioning plates arranged on two sides of the shoe nose and a plurality of material grabbing holes, and is characterized in that the edge of each material grabbing hole is provided with a plurality of arc-shaped folded edges positioned on one side of the cambered surface in the steel back body; the cambered surfaces in the steel back bodies at the two sides of the tile nose are fixedly connected with two circumferential steel bars and an axial steel bar, the two circumferential steel bars are positioned at the two sides of all the grabbing holes at one side of each steel bar, and the two circumferential steel bars are positioned between the axial steel bar at one side of each steel bar and the tile nose.
The edge of each material grabbing hole is provided with a plurality of arc-shaped folded edges positioned on one side of the inner arc surface of the steel backing body, the friction material laid by the material grabbing holes has a pinning effect, the gripping force on the friction material is good, and the material grabbing holes are provided with two circumferential steel bars and one axial steel bar to play a role in heat insulation and material grabbing on the friction material, so that the material grabbing holes are not deformed or loosened, and the braking effect can be ensured;
as a further improvement of the utility model, the tile nose is fixedly connected with the steel back body, the tile nose is provided with a pin hole, and the inner cambered surfaces of the steel back body at two sides of the tile nose are fixedly connected through a connecting plate; the tile nose and the steel back body are integrally and fixedly connected, the connecting plate can be prevented from deforming through punch forming, the connecting strength is high, the bearing capacity is large, the processing is convenient, and the production efficiency can be improved;
to sum up, the utility model discloses good, non-deformable, not hard up to friction material's the grip force, can guarantee braking effect, and joint strength is high, the bearing capacity is big, can improve production efficiency.
