Abstract
The utility model relates to a brake disc specifically is a high -speed rail train brake disc. The utility model provides a high -speed rail train brake disc's heat dissipation problem, including two concentric brake discs of arranging, the brake disc middle part is the mounting hole, and the mounting hole inward flange is equipped with the connecting block, is equipped with the connection blade between two brake discs, the outer fringe height of connection blade exceed brake disc outer fringe 2 3cm's distance, two edges and the brake disc of connection blade connect as an organic wholely, the connection blade with the brake disc centre of a circle according to interval 30 40 the poor setting forms airflow channel between two adjacent connection blades, the connection blade be turbine blade. Compared with the prior art, high -speed rail train brake disc design, rational in infrastructure, especially used turbine blade as the heat sink, can effectively cool down to the brake disc, has ensured train safety and has prolonged the life of brake disc.
Description
Technical field
This utility model relates to a kind of brake disc, is specially a kind of high ferro train brake disk.
Background technology
Bullet train, speed reaches 300-400 kilometer per hour.Its braking is a key technology, and existing brake unit relies primarily on the friction of brake shoe and brake disc to realize the effective brake of high ferro train.Brake disc is general and axletree connects, and brake disc and wheel are the most rotate at high speed.During frictional damping, brake disc temperature rises rapidly, can reach thousands of degree.High temperature typically can affect frictional behaviour, and therefore in addition to improving in disc material, the structure of brake disc is the most critically important, and good brake disc requires that cooling is wanted rapidly, and the cooling of brake disc is carried out mainly by air-cooled.And find under study for action, traditional brake disc is on air flowing not impact, and high-temperature brake dish uniformly heated the air of surrounding, although the train of high-speed motion makes rapid air movement to take away heat, but also it is detrimental to the quick diffusion of heat, thus constrains the service life of brake disc.
Summary of the invention
This utility model is in order to solve the heat dissipation problem of high ferro train brake disk, it is provided that a kind of high ferro train brake disk.
The technical solution of the utility model is, a kind of high ferro train brake disk, including two concentric arrangement of brake discs, it it is installing hole in the middle part of brake disc, installing hole inward flange is provided with contiguous block, connection blade it is provided with between two brake discs, the described outer rim high distance beyond brake disc outer rim 2-3cm connecting blade, described two edges connecting blade and brake disc connect as one, described connects arranging with the brake disc center of circle of blade according to 30-40 ° of interval difference, forming gas channel between two adjacent connection blades, described connection blade is turbo blade.
So, during the high-speed rotation of brake disc, connect blade and by force the air of brake disc end face is directed between two brake discs, and be pooled in the middle part installing hole of brake disc, and quickly discharge from the side of installing hole, it is achieved Efficient air rate is air-cooled.
Compared with prior art, high ferro train brake disk described in the utility model designs, rational in infrastructure, especially employs turbo blade as heat sink, effectively can lower the temperature brake disc, it is ensured that train safe and extend service life of brake disc.

In figure: 1-connects blade, 2-brake disc, 3-contiguous block.
Detailed description of the invention
Such as Fig. 1, 2, 3 are illustrated, a kind of high ferro train brake disk, including two concentric arrangement of brake discs 2, it it is installing hole in the middle part of brake disc 2, installing hole inward flange is provided with contiguous block 3, connection blade 1 it is provided with between two brake discs 2, the described outer rim high distance beyond brake disc outer rim 2-3cm connecting blade 1, described two edges connecting blade 1 and brake disc 2 connect as one, described connects arranging with the brake disc center of circle of blade 1 according to 30-40 ° of interval difference, gas channel is formed between two adjacent connection blades 1, described connection blade 1 is turbo blade.
Connect blade 1 two brake discs 2 to be tightly coupled together.Forming gas channel between two adjacent connection blades 1 is shape wide outside and narrow inside, and air-flow crushing failure at high speed can enter middle part installing hole.
