Abstract

The utility model discloses a novel brake pad structure of a high-speed train, which is characterized in that the brake pad is in a dual-arc shape formed by cutting a part from two sides of a circle in a parallel and symmetrical way, and no hole is arranged in the middle of the brake pad. The powder metallurgic brake pad structure of the high-speed train has the advantage of simple structure, the mold is easy to process, and the density of a molded blank is uniform. By using the design without the hole, a brake disk is not damaged when the brake pad is braked under the weather conditions of rain, snow and the like.

Description

A kind of high speed train powder metallurgy brake lining structure
Technical field
The utility model relates to a kind of high speed train powder metallurgy brake lining structure, belongs to the powder metallurgy friction material field.
Background technique
Powder metallurgy friction material is to be matrix with metal and alloy thereof, adds friction constituent element and lubricant component, the composite material made from powder metallurgy process.Powder metallurgy friction material has enough intensity, suitable and stable friction factor, and stable working is reliable, and is wear-resisting and pollute advantages such as few, is to use one of material more widely in the modern braking material family.
Present China rapid economic development, the railway passenger and freight transport volume increases sharply, and the speed up of railway transport has become inevitable development trend.China has opened the above bullet train of speed per hour 300km at present.The train speed up is had higher requirement to the brake pad that braking system has very high requirement, particularly braking system, and wherein technology is the most ripe, most widely used is the powder metallurgy brake pad.
The brake lining that powder metallurgical technique is made is assembled on the brake plate support, refills to be fitted in the braking system.In order to make the brake lining reliable contact brake disc in braking process that is installed on the brake plate support, the arrangement of brake lining on brake plate support keeps appropriate gap.And in order to make brake lining held stationary in braking process, brake lining all is designed to definite shape.Existing brake lining shape comprises circle, Hexagon, triangle.In the brake lining of these shapes, circular brake lining simple shape, forming die processing is also simple, is easy to make, but can not forms constraint each other each other when being assembled on the brake plate support, rotates easily, brakes not steady.Though triangle and hexagonal brake lining can form dependence each other, the corner is many, and forming die is difficult for processing, and forming process frictional force is big.
In addition, in the existing brake lining, some brake lining needs for installing to connect, and has the hole.Abrasive dust can be stored in this hole in braking process, but in sleety weather, sand and dust and abrasive dust form mud easily, causes the brake disc damage.
Summary of the invention
The utility model provides a kind of novel brake lining structure, is used to overcome above deficiency.
Brake lining of the present utility model is an a kind of pair of arc structure, and its shape is with the parallel two arcuations that cut away part formation symmetrically in the both sides of circle, and does not have the hole in the middle of the brake lining.
This pair of arc structure of the present utility model cuts a part with circular both sides symmetry and forms, and simple in structure, Mould Machining is easy, and the shaping blank density is even.And use design not with holes, do not damage brake disc when brake lining is braked under weather conditions such as sleet.
Description of drawings
Fig. 1 is some brake lining structures of prior art;
Fig. 2 is a brake lining structure of the present utility model.
Embodiment
The utility model is described with reference to the accompanying drawings.
Fig. 2 is the brake lining of bullet train of the present utility model, and its shape is with the parallel two arcuations that cut away part formation symmetrically in the both sides of circle, and does not have the hole in the middle of the brake lining.Circle is cut away the remaining width in part back and is accounted for 1/3～1/4 of original round diameter.The too little friction area that then needs more brake lining to reach design of width, manufacture cost increases.Width is too greatly then close with circle, does not have effect.
This pair of arc structure of the present utility model cuts a part with circular both sides symmetry and forms, and simple in structure, Mould Machining is easy, and the shaping blank density is even.And use design not with holes, do not damage brake disc when brake lining is braked under weather conditions such as sleet.

Claims (2)

1. the brake lining of a bullet train, the shape that it is characterized in that brake lining are to cut away two arcuations that a part forms symmetrically with the both sides of circle are parallel, and the brake lining centre does not have the hole.
2. brake lining according to claim 1 is characterized in that the width of two arcuations is 1/3～1/4 of circular diameters.
