Description

Used for rail vehicle brake disc and rail vehicle
Technical field
The present invention relates to the railway vehicle device technology, relate in particular to a kind of used for rail vehicle brake disc and rail vehicle.
Background technique
At present, brake disc has been widely used in the braking system of rail vehicle.The disc-shaped brake device that is comprised of brake disc and disc brake unit etc. has compact structure, characteristics that retardation efficiency is high.
In the prior art, brake disc comprises friction ring, hub and fastening piece, and friction ring is connected by fastening piece with the hub seat of hub, must reserve the installing space of fastening piece between friction ring and the hub seat.
In order to reduce the rail vehicle truck unsprung weight and to reduce floor of railway vehicle face height, on low floor vehicle, light rail vehicle and part narrow gauge bogie, adopt at present small diameter wheels more.Because the reduction of floor and the minimizing of wheel diameter, so that the design of the diameter of brake disc is more and more less.The brake disc of usefulness is owing to structural limitations, so that after the brake disc diameter reduced, the effective area of contact in the disc-shaped brake device working procedure between brake disc and brake pad reduced, thereby affects braking ability at present.
Summary of the invention
The invention provides a kind of used for rail vehicle brake disc and rail vehicle, to improve braking ability.
The invention provides a kind of used for rail vehicle brake disc, comprising:
Hub comprises the hub seat, and described hub seat is connected with web, and described web is along circumferentially being evenly equipped with the first attachment hole;
Two friction rings are arranged at respectively the both sides of described hub, and each described friction ring is respectively equipped with second attachment hole corresponding with described the first attachment hole;
Fastening piece is arranged in described the first attachment hole and the second attachment hole, and described hub is fixedly connected with friction ring, and the two end part of described fastening piece are depressed in respectively in the rubbing surface of described friction ring.
The invention provides a kind of rail vehicle, comprise disc-shaped brake device, described disc-shaped brake device comprises used for rail vehicle brake disc provided by the present invention.
Based on above-mentioned, a kind of used for rail vehicle brake disc provided by the invention, because friction ring adopts fastening piece to be connected with the web of hub, therefore need not reserve again installing space between friction ring and the hub seat, therefore effectively increased the area of rubbing surface, improve the braking ability of brake disc, in the situation that the brake disc diameter reduces, still can guarantee area and the braking ability of enough rubbing surfaces.

Embodiment
Please refer to Fig. 1-3, the embodiment of the invention provides a kind of used for rail vehicle brake disc, comprising: hub 101, comprise hub seat 102, and described hub seat 102 is connected with web 103, and described web 103 is along circumferentially being evenly equipped with the first attachment hole 104; Two friction rings 105 are arranged at respectively the both sides of described hub 101, and each described friction ring 105 is respectively equipped with second attachment hole 106 corresponding with described the first attachment hole 104; Fastening piece 107 is arranged in described the first attachment hole 104 and the second attachment hole 106, and described hub 101 is fixedly connected with friction ring 105, and the two end part of described fastening piece 107 are depressed in respectively in the rubbing surface of friction ring 105.
In the present embodiment, fastening piece 107 can adopt screw bolt and nut also can adopt other fastening pieces 107.During use, can first hub 101 be press-fited with axletree on friction ring 105 is installed again, also can be first then hub 101 and friction ring 105 be assembled disk-braking press mounting on axletree.Because friction ring 105 adopts fastening piece 107 to be connected with the web 103 of hub 101, therefore need not reserve again installing space between friction ring 105 and the hub seat 102, therefore effectively increased the area of rubbing surface, improved the braking ability of brake disc, in the situation that the brake disc diameter reduces, still can guarantee area and the braking ability of enough rubbing surfaces, therefore be beneficial to the application of small diameter wheel, simultaneously, because the two end part of fastening piece 107 are depressed in respectively in the rubbing surface of friction ring 105, therefore can the work of brake disc not exerted an influence.
In the present embodiment, preferably, the non-rubbing surface of friction ring 105 is provided with radiating fin 108, air-flow can pass through between the web 103 of friction ring 105 and hub 101 when braking, the heat of radiating fin 108 is left, can prevent that thus friction ring 105 is overheated, simultaneously, radiating fin 108 also can be used for supporting friction ring 105, increases the intensity of friction ring 105.
In the present embodiment, preferred, radiating fin 108 is radial arrangement, can further improve thus radiating effect.
In the present embodiment, preferred, position by locating stud 109 between friction ring 105 and the hub 101.Locating stud 109 can transmit the moment of torsion in the braking process, thereby avoids fastening piece 107 because damaged by shearing force.
In the present embodiment, preferred, friction ring 105 is put together by at least two friction ring assemblies.Friction ring 105 in use can produce wearing and tearing, when needing to change when friction ring 105 serious wear, because friction ring 105 is put together by at least two friction ring assemblies, therefore need not brake disc is unloaded from axletree, only need unload the friction ring assembly respectively and get final product from hub 101, friction ring 105 are changed convenient.Certainly friction ring 105 also can be overall structure, and the present invention is not specifically limited this.
The embodiment of the invention provides a kind of rail vehicle, comprises disc-shaped brake device, and described disc-shaped brake device comprises the described used for rail vehicle brake disc of any embodiment of the present invention.
In the present embodiment, because friction ring 105 adopts fastening piece 107 to be connected with the web 103 of hub 101, therefore need not reserve again installing space between friction ring 105 and the hub seat 102, therefore effectively increased the area of rubbing surface, improved the braking ability of brake disc, in the situation that the brake disc diameter reduces, still can guarantee area and the braking ability of enough rubbing surfaces, therefore be beneficial to the application of small diameter wheel, simultaneously, because the two end part of fastening piece 107 are depressed in respectively in the rubbing surface of friction ring 105, therefore can the work of brake disc not exerted an influence.
The used for rail vehicle brake disc that the embodiment of the invention provides, the topology layout compact and reasonable can reduce the diameter of brake disc under the prerequisite that guarantees the effective friction area of brake disc, be specially adapted to require the rail vehicle of minor diameter brake disc to select.
It should be noted that at last: above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that previous embodiment is put down in writing, and perhaps some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of embodiment of the invention technological scheme.
