Abstract
The utility model discloses a composite brake shoe for railway locomotive, which comprises an associated shoe back and a friction body, wherein the shoe back 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 two positioning gears fixedly arranged on two sides of the shoe nose, and is characterized in that the positioning gears comprise two parallel positioning blocks passing through the steel back body, the distance between the two positioning blocks and the center line of the shoe nose is equal, and the steel back body is fixedly connected with all the positioning blocks by welding on one side of the inner arc surface; the steel back bodies on two sides of the tile nose are provided with more than two cylindrical material grabbing holes. The utility model has the advantages of structure and processing are comparatively simple, have reduced the comprehensive cost of brake shoe, have improved production efficiency.
Description
Technical Field
The utility model relates to a synthetic brake shoe for railway locomotive.
Background
The composite brake shoe of the railway locomotive is arranged on a locomotive shoe support of a braking system and needs to bear larger load; the composite brake shoe is formed by connecting a shoe back and a friction body through a connecting adhesive and pressing, and the friction body material of the existing composite brake shoe for the railway locomotive needs to be provided with a more complex positioning rail and a material grabbing hole on a steel back body of the shoe back because the strength of the friction body material is low so as to avoid the falling of the shoe back and improve the bearing capacity, but the structure and the processing of the shoe back are complex, so that the comprehensive cost of the brake shoe is improved, and the production efficiency is reduced.
Disclosure of Invention
The utility model aims at the above-mentioned not enough that prior art exists, provide a synthetic brake shoe for railway locomotive, it has the comparatively simple advantage of structure and processing, has reduced the comprehensive cost of brake shoe, has improved production efficiency.
In order to achieve the above purpose, the composite brake shoe for railway locomotive of the present invention comprises an associated shoe back and a friction body, wherein the shoe back 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 two positioning steps fixedly arranged on both sides of the shoe nose, and is characterized in that the positioning steps comprise two parallel positioning blocks passing through the steel back body, the distance between the two positioning blocks and the center line of the shoe nose is equal, and the steel back body is fixedly connected with all the positioning blocks by welding on one side of the inner arc surface; the steel back bodies on two sides of the tile nose are provided with more than two cylindrical material grabbing holes.
The positioning gear of the utility model is two positioning blocks which are parallel, the material grabbing hole is cylindrical, compared with the prior art, the material grabbing device has the advantages of simpler structure and simpler processing, reduces the comprehensive cost of the brake shoe and improves the production efficiency;
as a further improvement of the utility model, the cylindrical material grabbing holes are circumferentially positioned between two positioning blocks at two sides of the tile nose; the two positioning blocks are arranged on two sides of the cylindrical material grabbing hole, so that a better braking effect is achieved on the shoe support, and the bearing capacity of the brake shoe can be further increased;
to sum up, the utility model has the advantages of structure and processing are comparatively simple, have reduced the comprehensive cost of brake shoe, have improved production efficiency.

Fig. 2 is a front view of the tile back of fig. 1.
Fig. 3 is a top view of fig. 2.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the composite brake shoe for railway locomotive comprises a shoe back 1 and a friction body 2 which are connected, wherein the shoe back 1 comprises an arc-shaped steel back body 3, a shoe nose 4 arranged in the middle of one side of the outer arc surface of the steel back body, and two positioning steps fixedly arranged on two sides of the shoe nose 4, the positioning steps respectively comprise two parallel positioning blocks 5 penetrating through the steel back body 3, the distances between the two positioning blocks 5 and the central line of the shoe nose 4 are equal, and the steel back body 3 is fixedly connected with all the positioning blocks 5 on one side of the inner arc surface in a welding manner; the steel back body 3 on both sides of the tile nose 4 is provided with two cylindrical material grabbing holes 6.
The utility model discloses a cylindrical material hole 6 of grabbing is embedded into to friction member 2 after the shaping, because friction member 2 adopts the synthetic material that highly rubs (like resin with friction regulator) that intensity is higher, the location shelves change into two parallel locating pieces 5, grab material hole 6 and change into cylindrically, compared with prior art have structure and process comparatively simple advantage, reduced the comprehensive cost of brake shoe, improved production efficiency; the two positioning blocks 5 are arranged on two sides of the cylindrical material grabbing hole 6, so that a better braking effect is achieved on the shoe support, and the bearing capacity of the brake shoe can be further increased.
