Description
Technical field
The present invention relates to high-speed train braking device, relate in particular to the brake disc in high-speed train braking device.
Background technique
Along with the raising of train running speed, the braking force of train and braking temperature rise are also more and more higher.Be widely used because disc type brake has significant advantage at aspects such as braking force, the heat damages of minimizing wheel tread compared with other friction catch form, disc type brake has become bullet train and has finally realized the requisite brake riggings mode of stopping.
Disc type brake is to obtain braking force by the friction between brake disc and brake lining, once produce friction, the temperature at brake disc and brake lining Contact friction position just rises, and the faster temperature rise of car speed is just higher.Brake disc is subject to after frictional heating, and temperature raises and not only can cause the ablation on contact friction surface, and the thermal stress that friction pair interaction produces also can cause the thermal creep of brake disc and thermal fatigue to damage.
Application for a patent for invention (application number 201110244664.9) discloses a kind of brake disc of high-speed train structure, and this brake disc of high-speed train comprises disk body, and is positioned at rubbing surface and inner side surface on disk body.For the consideration of moulding process and disk body intensity, this application for a patent for invention is also provided with the first radial plate-like radiating fin and the second radial plate-like radiating fin on disk body inner side surface, and its heat dispersion is mainly realized by material component and radial plate-like radiating fin.Although the heat dissipation plate of this structure can be obtained certain radiating effect by heat dissipation plate radially, but the stirring heat radiation of its radial plate-like radiating fin to brake disc surrounding atmosphere, more to rely on around braking device ambient air eddy current, the hot air range of scatter that vortex is mobile and diffusion velocity are all very limited, especially in the time that bullet train motion speed is on 300km/h, the heat dissipation rate of this brake disc is always less than friction Temperature Rise, make the braking device of bullet train always in the larger bad working environments of heat load, easily cause the quickening of high-speed train braking device to lose efficacy or lost efficacy in advance.Given this how making the brake disc can high efficiency and heat radiation, be the current technical issues that need to address to improve brake disc working life.
Summary of the invention
For the existing above-mentioned deficiency of prior art, technical problem to be solved by this invention is to provide a kind of brake disc of high-speed train with forced heat radiation muscle, it can, by brake disc surrounding atmosphere mandatory guidance, accelerate the rapid diffusion of frictional heat, avoids friction disk temperature rise too high.
In order to solve the problems of the technologies described above, the brake disc of high-speed train with forced heat radiation muscle of the present invention, comprise the disk body with disk body rubbing surface and the disk body back side, on disk body, be provided with disk body mesopore and radiating fin, described radiating fin is circular arc list structure, ratio R/D=0.4～0.6 of the radius of arc R of this radiating fin and disk body outer diameter D; The inflow angle β of radiating fin
1=0～15 °, the drainage angle β of radiating fin
2=25～35 °; Between adjacent two radiating fin, form ventilation slot, be provided with the radiation hole that passes to disk body rubbing surface in the bottom of this ventilation slot; Ratio B2/B1=1.0～1.2 of the height B 2 of described radiating fin and the thickness B 1 of disk body.
In said structure, because radiating fin is circular arc list structure, between adjacent radiating fin, form the ventilation slot that is equally circular arc bathtub construction, the radiating fin of this circular arc convex rib structure and the ventilation slot of arcuate structure, have concurrently radially and multidirectional air-flow forced guide function such as tangential in when braking, guiding brake disc body side surface air radially, tangentially even axial quick diverging flow outside disk body, form the air flow field of energy high speed flow through radiating fin side and ventilation slot bottom land, realize brake disc has been forced to lasting ventilation and heat, accelerate the diffusion of friction catch heat.Again because the ratio R/D of radiating fin radius of arc and disk body external diameter is in the present invention chosen between 0.4～0.6, and heat dissipation plate inflow angle β
1=0～15 °, drainage angle β
2=25～35 °, lot of experiments proves the selection of these parameters, bullet train travelling speed radiating fin when 200～400km/h is formed to pump wind drafting efficiency the highest, air is changed mobile the fastest, the gas flow of ventilation slot of flowing through is more smooth and easy, and coiling outer cool air can enter in groove from ventilation notch efficiently, and is flowed out by groove outer end with a large amount of frictional heats, make large part frictional heat be delivered to surrounding space in thermoconvection mode, form rational air flow field and efficient radiating effect.Also due to the present invention preferred radiating fin height and disk body thickness proportion, be conducive to the rapid diffusion of frictional heat, realized brake disc wind-guiding efficiency and fabrication and installation process synthesis effect; Too low radiating fin height can not reach effective pump wind ventilation effect, form and do not become rational oxygen diffusion field, and too high radiating fin obviously affects the air velocity on ventilation slot bottom land surface, and increase the moulding process difficulty of radiating fin, strengthened the installing space of brake disc.In the present invention, be also provided with at ventilation slot bottom land the radiation hole that passes to disk body rubbing surface, the heat that this radiation hole can not only directly produce rubbing surface brings to ventilation slot and distributes with Air Flow, and can play good row's powder effect, thereby there is height and stable friction factor; Evidence repeatedly, the present invention can strengthen targetedly the guiding of disc surfaces air and flow bullet train, increase by 30% left and right than existing brake disc heat diffusion area, braking force improves 12% left and right, and preparation process of the present invention is reasonable, installation and maintenance are convenient, and structural strength is high, long service life.
The preferred embodiment of the present invention, the ratio R/D=0.5 of described radiating fin radius of arc R and disk body outer diameter D; Radiating fin inflow angle β
1=10 °, the drainage angle β of radiating fin
2=30 °, the height B 2 of radiating fin and disk body thickness B 1 than B2/ B1=1.1.The each parameter of brake disc of this structure is coordinated rationally more, better for high-speed train braking radiating effect.
On the described disk body back side, be provided with mounting hole boss, on mounting hole boss, be provided with mounting hole.
The width of rebate of described ventilation slot is 40mm～50mm.
The sectional shape of described radiating fin is rectangle or trapezoidal.
Described disk body adopts overall structure or Split type structure.
