The utility model discloses install the both sides at the train wheel respectively at the during operation, and along the axisymmetric distribution, the mounting hole suit on the brake disc disk body 1 is on the train wheel axle, brake disc installation face 12 is towards the wheel face when the installation, and brace rod 3 on the installation face 12 is laminated with the train wheel side mutually, brace rod 3 not only plays the effect of supporting the installation, more can play radiating effect, so brace rod 3 divides into location brace rod 313 and heat dissipation brace rod 323, and set up location round platform 311 and locating hole 312 on location brace rod 313, locating hole 312 sets up on location round platform 311, and pass locating hole 312 through positioning bolt and be connected with the train wheel, and then firmly fix the brake disc on the train wheel;
in order to accelerate the heat dissipation of the tray body 1, the supporting ribs 3 are designed to be U-shaped, wherein the U-shaped surface is smaller than the base surface of the tray body 1 and is smaller in contact with the wheel rim of a train, so that a large enough gap is reserved between the tray body 1 and the train wheels to allow air to circulate, and the supporting ribs 3 are distributed at intervals to allow air to enter from the edge of the tray body 1 to cool the tray body 1.
Further, a plurality of U-shaped grooves are formed between the U-shaped support ribs 3 and train wheels after the disc body 1 is installed, when the brake disc rotates along with the wheels, air enters the disc body 1 from gaps among the U-shaped support members 3, flows out from the installation holes of the disc body 1, and flows to the outside through holes of the planar ring 22 of the flange 2, so that the air circulates;
when the brake disc is installed on a train wheel, the U-shaped supporting rib and the wheel surface form a U-shaped groove with an opening, air can enter the U-shaped groove when the brake disc rotates, and the air rapidly flows out in the process of rapid rotation of the brake disc due to the fact that the U-shaped groove is only provided with one opening, so that the purpose of rapidly replacing the air to achieve refrigeration is achieved.
Further, the fixing flange 2 arranged on the brake disc working surface 11 is correspondingly arranged on a train wheel, the fixing flange 2 consists of a cylindrical ring 21 and a planar ring 22, the cylindrical ring 21 is arranged along the mounting hole on the brake disc body 1 and is superposed with the axis of the mounting hole, so that the cylindrical ring 21 is sleeved at the axle end of the train wheel, namely, the fixing flange 2 is correspondingly sleeved at the axle end of the train wheel, the planar ring 22 is provided with a connecting hole 23, the flange and the train wheel are fixed through a bolt, and the flange and the disc body 1 are fixedly arranged, so that the stability of the wheel-mounted brake disc during braking is stabilized again through the flange.
Further, the cylindrical ring 21 side of the fixing flange 2 has a draft.
Furthermore, a plurality of connecting holes 23 are formed in the plane ring 22 of the fixed flange 2, and the connecting holes 23 are uniformly distributed along the circular ring surface of the plane ring 22.
Further, the U-shaped openings of the positioning support ribs 313 and the heat dissipation support ribs 323 are all outward along the mounting surface 12.
Further, the positioning support rib 313, the heat dissipation support rib 323, and the positioning round table 311 are all the same in height.
Further, the size of the mounting hole is consistent with the size of the flange cylindrical ring 21.
When the train need the brake at the in-process that traveles, let calliper embrace the brake disc through braking control system, calliper braking end and the 11 contacts of brake disc working face to take place the friction at the process of braking, produce a large amount of heats simultaneously, make the temperature of brake disc rise, and the frictional heating can influence the stability of brake disc, thereby further influence the braking effect, so set up heat dissipation brace rod 323 and accelerate the heat dissipation, set up the stability that fixing flange 2 strengthened the brake disc.
Further, in order to achieve a better heat dissipation effect, the heat dissipation support ribs 323 and the positioning support ribs 313 are distributed uniformly in a crossed manner, and the openings of the U shapes face the outside of the brake disc body 1, because the brake disc body 1 is circular, the support ribs 3 are distributed along the circular circumference, so that the gap formed between each support rib 3 is triangular, and the gap between the support ribs 3 forms two openings, namely, a small opening close to the center of the disc body 1 and a large opening close to the edge of the disc body 1, the advantage of the distribution of the openings is that the heat generated during the working of the disc body 1 flows into the large opening from the small opening under the action of the rotation inertia, and flows out from the large opening, so that the flow speed is high, and the relative heat dissipation is high.
Furthermore, as the brake disc needs to be fixed on the train wheel, the positioning round platforms 311 and the positioning holes 312 are arranged on the U-shaped support ribs 3, the brake disc is fixed on the train wheel by using the positioning bolts, the U-shaped support ribs 3 are convenient for arrangement of the round platforms, and the round platforms are also the disc bodies 1 which are uniformly heated.
Further, because expend with heat and contract with cold's the reason, can lead to the fixed between disk body 1 and the train wheel to change, so set up the fixed of flange 2 enhancement brake disc on original brake disc disk body 1, make the train can be more firm when the braking, do not take place to become flexible, thereby influence braking effect, so set up connecting hole 23 on flange 2 plane ring 22, and connecting hole 23 evenly distributed is on plane ring 22, connecting bolt passes through connecting hole 23 and is connected flange 2 and train wheel, carry out the secondary to brake disc and train wheel promptly and fix, further improve the stability of brake disc during operation.
Further, in order to prevent the increase of the fixing flange 2 from hindering the heat dissipation, a central heat dissipation hole is formed at the middle position of the planar ring 22 of the fixing flange 2, and the central heat dissipation hole is also convenient for the installation of the brake disc.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
