Description
Technical field
The utility model belongs to locomotive brake field, particularly relates to a kind of EMU axle-mounted brake disk.
Background technique
Brake disc is the critical component of high speed motor car, plays an important role when motor-car is braked, and because its working environment is complicated severe, maintain and replace inconvenience, requires that brake disc product must hold more stable heat dissipation potential and longer working life.And the heat of the brake disc used at present often can not leave in time, thus initiation heat fade causes Braking efficiency to decline, directly affect its working life, the brake disc in addition on market often adopts casting or simple forging and stamping to form, and its material capability or heat dispersion often do not reach requirement.
Summary of the invention
The technical problems to be solved in the utility model is, for the deficiencies in the prior art part, provides a kind of EMU axle-mounted brake disk, its heat dispersion and material mechanical property good, long service life.
The technical scheme in the invention for solving the technical problem is: EMU axle-mounted brake disk, comprise braking inner disc, braking outer disk and heat dissipation column, one group of contiguous block is installed with between described braking inner disc and braking outer disk, contiguous block circumferentially distributes along the interior annular distance of braking outer disk, gap between braking inner disc and braking outer disk forms the supporting zone of described heat dissipation column, described braking outer disk offers the some groups of radiation holes distributed ringwise, described radiation hole is accordingly through described braking inner disc, the number of described radiation hole outwards increases successively from the center of annular, and the center line of described radiation hole is 60 degree with the surperficial angle of braking outer disk, a heat dissipation column is all welded in radiation hole, described heat dissipation column is cylindrical, its diameter is 18-22mm, the two ends of described heat dissipation column are fixedly arranged in the braking outer disk radiation hole corresponding with braking inner disc respectively.
Described braking outer disk offers 2 groups of radiation holes distributed ringwise, and one group is provided with 12 radiation holes, and another group is provided with 6 radiation holes.
The beneficial effects of the utility model are: EMU axle-mounted brake disk of the present utility model, be provided with some radiation holes, alleviate disk body quality, braking and perfect heat-dissipating, and adopt the mode of forge weldling, heat dissipation column is welded between two brake discs, ensure effective heat diffusion area, improve rubbing surface metal material mechanics performance, thus improve brake disc whole service life and usability; Described contiguous block serves the reinforcement by connection effect of braking inner disc and braking outer disk, and be convenient to increases stirring air when it rotates simultaneously, strengthens air circulation, the heat Accelerating Removal that braking is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.In figure:
1. brake inner disc, 2. brake outer disk, 3. heat dissipation column, 4. contiguous block, annular distance 5., 6. radiation hole.
Embodiment
The technical solution of the utility model is further illustrated below by specific embodiment.
As shown in Figure 1-2: EMU axle-mounted brake disk, comprise braking inner disc 1, braking outer disk 2 and heat dissipation column 3, described braking inner disc 1 and braking outer disk 2 adopt forging and stamping to form; Between described braking inner disc 1 and braking outer disk 2, be installed with one group of contiguous block 4, described contiguous block 4 circumferentially distributes along annular distance 5 in braking outer disk 2; The cross section of described contiguous block 4 can be rectangle or isosceles trapezoid; The use of contiguous block 4, serve the reinforcement by connection effect of braking inner disc 1 and braking outer disk 2 on the one hand, add the area of contact with air on the other hand, be convenient to increase stirring air when it rotates, strengthen air circulation, the heat Accelerating Removal that braking is produced, is convenient to reduce the heat be delivered on wheel hub.
Gap between braking inner disc 1 and braking outer disk 2 forms the supporting zone of described heat dissipation column 3, described braking outer disk 2 offers the some groups of radiation holes distributed ringwise 6, described radiation hole 6 is accordingly through described braking inner disc 1, the number of described radiation hole 6 outwards increases successively from the center of annular, for better heat radiation, described braking outer disk 2 offers 2 groups of radiation holes distributed ringwise 6, a group and is provided with 12 radiation holes 6, another group is provided with 6 radiation holes.
For being more conducive to heat radiation, angle is there is in the center line of described radiation hole 6 with the surface of braking outer disk 2, described angle is 60 degree, a heat dissipation column 3 is all welded in described radiation hole 6, EMU axle-mounted brake disk of the present utility model adopts the mode of forge weldling, is welded on by heat dissipation column 3 between braking outer disk 2 and braking inner disc 1, adds effective heat diffusion area, improve the mechanical property of rubbing surface metallic material, and then improve brake disc whole service life and usability.
Described heat dissipation column 3 is cylindrical, its diameter is 18-22mm, the inside being fixedly arranged on braking outer disk 2 and its radiation hole 6 of braking inner disc 1 that the two ends of described heat dissipation column 3 are corresponding respectively, forms air-flow path between described heat dissipation column 3, when being convenient to brake produce the discharge of heat.
EMU axle-mounted brake disk of the present utility model, be provided with some radiation holes 6, alleviate disk body quality, make brake disc light durable, braking and perfect heat-dissipating, and adopt the mode of forge weldling, heat dissipation column is welded between two brake discs, ensure effective heat diffusion area, improve rubbing surface metal material mechanics performance, thus improve brake disc whole service life and usability.
Except technical characteristics described in specification, be those skilled in the art known technology.
