Abstract
The utility model discloses a high-phosphorus brake shoe back for railway vehicles, which comprises an arc-shaped steel back body, a shoe nose arranged in the middle of one side of the outer cambered surface of the steel back body, and a pin hole arranged in the shoe nose, wherein both ends of the steel back body are respectively provided with a notch, two parallel reinforcing ribs are fixedly connected with one side of the inner cambered surface of the steel back body, and the middle parts of the reinforcing ribs are respectively provided with a bending section positioned in the shoe nose; the inner arc surfaces of the steel back bodies on the two sides of the tile nose are fixedly connected through the reinforcing plate. The utility model has the advantages of intensity is high, non-deformable to guarantee the friction member and the good contact of wheel, improve braking effect and security.
Description
Technical Field
The utility model relates to a high phosphorus brake shoe tile back for railway vehicle.
Background
The brake shoe back of the railway locomotive is arranged on a locomotive shoe support of a braking system and needs to bear larger load; the brake shoe back of the existing railway locomotive comprises an arc-shaped steel back body, a shoe nose arranged in the middle of one side of the outer arc surface of the steel back body and a pin hole arranged in the shoe nose; the pad nose is fixedly connected to the pad support through a pin shaft penetrating through a pin hole, and a friction body is arranged on one side of the inner arc surface of the steel back body and is in contact with the wheel to brake; however, the friction body made of cast iron is laid on the tile back due to the heavy weight of the friction body, the tile back is easy to deform due to insufficient strength, the contact between the friction body and the wheel is affected, and the braking effect and the safety are poor.
Disclosure of Invention
The utility model aims at the above-mentioned not enough that prior art exists, provide a railway vehicle is with high phosphorus brake shoe tile back of body, it has intensity height, non-deformable's advantage to guarantee the good contact of friction body and wheel, improve braking effect and security.
In order to achieve the purpose, the high-phosphorus brake shoe back for the railway vehicle comprises an arc-shaped steel back body, a shoe nose arranged in the middle of one side of the outer cambered surface of the steel back body and a pin hole arranged in the shoe nose, and is characterized in that both ends of the steel back body are provided with notches, one side of the cambered surface in the steel back body is fixedly connected with two parallel reinforcing ribs, and the middle parts of the reinforcing ribs are provided with bending sections positioned in the shoe nose; the inner arc surfaces of the steel back bodies on the two sides of the tile nose are fixedly connected through the reinforcing plate.
The utility model has the advantages that the strength of the tile back can be effectively improved by arranging the two reinforcing ribs and the reinforcing plate, the friction body made of cast iron is not easy to deform, and the binding force between the tile back and the friction material is enhanced, so that the good contact between the friction body and the wheel is ensured, and the braking effect and the safety are improved; the notch can also improve the bonding strength after the cast molten iron is solidified;
as a further improvement of the utility model, the steel back body at the bottom of each notch is provided with a section of folded edge which is positioned at one side of the cambered surface in the steel back body; the folding edge can further improve the bonding strength of the tile back and the friction body;
as a further improvement of the utility model, a baffle plate is arranged in the tile nose between the bending sections of the two reinforcing ribs and is fixedly connected with the reinforcing plate; the pin shaft penetrates through the partition plate, so that the deformation of the tile nose can be reduced;
to sum up, the utility model has the advantages of intensity is high, non-deformable to guarantee the good contact of friction member and wheel, improve braking effect and security.
