Description
Technical field
The utility model belongs to for motor vehicle brake block technical field of high-speed overload, and in particular to a kind of high-speed rail train is efficient
Braking brake block.
Background technique
Currently, the High-speed Railway Network construction speed in China is at the forefront in the world, there are more and more motor-car travelings to exist in recent years
On high-speed railway, the speed of service of train is also constantly being promoted, and incident wanted to the performance of brake system
Ask also higher and higher, if high-speed train braking is advocated by electric braking force and frictional force, and friction brake force is then train safety
The last guarantee of parking.Friction brake force is realized by the brake disc in braking system and the friction between brake block, and is made
The quality for piece performance and the structure of braking in dynamic system with rationally whether have very big influence to train braking effect.It is braking
In the process, brake block friction surface temperature reaches as high as 700 DEG C, and even higher, this just requires brake block to have enough first
Under high intensity and stiffness conditions, also to have good thermally conductive and heat resistance, also reliable reasonable structure design is to come
Guarantee good braking effect.The design of high-speed rail train brake device in the prior art, mostly uses greatly friction plate and brake disc
Frictional force is generated for face contact friction, and the shortcoming of this design is the braking as being that pressure caused by face contact is small
Distance, brake speed is slow, to influence the effect of emergency braking.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of high-speed rail train high-efficient brake piece.
A kind of high-speed rail train high-efficient brake piece of the utility model, is made of friction plate and backboard, friction plate be by
The front of carbon answer print and hoof block fits compositions, the inserting column at the back side of hoof block and the embedded connection of backboard；Backboard is covering of the fan
Shape steel plate, the mounting hole of the hoof block of arranged on planes friction plate, the back side of backboard be made of T-shaped and n font with braking
The inlay card muscle fin of device installation.
The mounting hole of the hoof block on backboard is also that laterally sector is equidistantly arranged as a further improvement of the utility model,
It arranges, aperture is to increase aperture, to be constituted in the hole slightly larger than the diameter of inserting column, the back segment aperture in the hole before mounting hole
The insertion clamping rings supporting table of circlip.
The fan-shaped surface of backboard is that symmetrical two panels is opposite to spell by being divided into axis as a further improvement of the utility model,
Composition is connect, there is the clamping groove of convex-concave each other on two end faces of docking.
The high-speed rail train high-efficient brake piece of the utility model has the characteristics that point contact braking, is made of multiple spot
Friction plate design, increases the opposite pressure generated when braking, so that increasing friction force, makes the contracting of distance required for braking
It is short, achieve the purpose that in emergency circumstances fast braking；Meanwhile friction block is point type permutation and combination, makes to produce inside brake block
Preferable permeability, air cooling effect is good, and heat diffusion is timely, and brake disc is avoided to overheat, and causes the accident.

Specific embodiment
A kind of high-speed rail train high-efficient brake piece of the utility model is described further with reference to the accompanying drawing:
As shown in Fig. 1-5, a kind of high-speed rail train high-efficient brake piece of the utility model is by 2 structure of friction plate 1 and backboard
At friction plate 1 is fitted by carbon answer print 3 and the front of hoof block 4, and the inserting column 5 and backboard 2 at the back side of hoof block 4 are embedded
Connection；The brake backboard is fan-like pattern steel plate, the mounting hole 6 of the hoof block 4 of arranged on planes friction plate 1, the back of backboard 2
The inlay card muscle fin 9 with brake installation that face is made of T-shaped and n font.
Wherein, the mounting hole 6 of the hoof block 4 on backboard 2 is also laterally fan-shaped arranged at equal intervals, aperture before mounting hole 6
It is to increase aperture, fixed with the insertion for constituting circlip 7 in the hole slightly larger than the diameter of inserting column 5, the back segment aperture in the hole
Arch brace platform 8.
In addition, the fan-shaped surface of backboard 2 is spliced to form relatively by being divided into symmetrical two panels with axis according to installation requirements,
There is the clamping groove of convex-concave each other on two end faces of docking.
