Abstract
The present invention relates to a kind of brake disc of high-speed train-wheel discs, are made of braking disk body, brake area, center positioning hole, uniformly distributed mounting hole, reinforcement boss, radial radiating ribs, transient equilibrium boss, it is characterised in that：The brake disc of high-speed train body center positioning hole is located on bullet train wheel, and by uniformly distributed mounting hole by being bolted, uniformly distributed mounting hole, which is distributed in, to be reinforced on boss.The heat generated during drag friction is disperseed by radial radiating ribs, and the vibrations of generation are eliminated by transient equilibrium boss.With good heat dissipation effect, severity of braking is high, and running under braking is steady, the strong advantage of safety and effectiveness.
Description
Technical field
The present invention relates to a kind of brake disc of high-speed train in field, specifically a kind of brake disc of high-speed train-wheel disc.
Background technology
It is well known that disc type brake is the brake riggings mode that bullet train realizes parking at present.With train operation speed
The raising of degree, brake safe, which has laughed at requirement, can also greatly improve, and higher temperature and larger is necessarily led to during train braking
Vibration influence braking effect, higher temperature and larger vibrations certainly will influence the safety of bullet train.
Invention content
The technical problem to be solved by the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of good heat dissipation effect,
A kind of brake disc of high-speed train-the wheeling disk structure for the advantages that severity of braking is high, running under braking is steady, safety and effectiveness is high.
The present invention solves above-mentioned technical problem and is adopted the technical scheme that：Brake disc of high-speed train body center positioning hole is fixed
Position is on bullet train wheel, and by uniformly distributed mounting hole by being bolted, uniformly distributed mounting hole, which is distributed in, to be reinforced on boss.Braking rubs
It wipes the heat generated in the process to radiate by radial radiating ribs, the vibrations of generation are eliminated by transient equilibrium boss.Reinforce boss
It is that the coupled radial radiating ribs tangent line of ellipse is connected.Reinforce boss to be uniformly distributed, there is mounting hole thereon.Braking
The heat generated in friction process is radiated by radial radiating ribs, radial radiating ribs include the first radial plate-like radiating ribs, second
Radial sector radiating ribs, third radial plate-like sector combine radiating ribs.
All radial direction radiating ribs are uniformly distributed at 7.5 °, and the second radial fan-shaped radiating ribs are R200-R210 sectors.First radial plate-like
The radial fan-shaped radiating ribs of radiating ribs second uniformly distribute alternately at 15 °.Third radial plate-like sector combines radiating ribs by 2 group first
The radial fan-shaped radiating ribs of 2 group second of radial plate-like radiating ribs and reinforcement boss composition, are uniformly braked on disk body.
Transient equilibrium boss is distributed at 60 ° in radial plate-like radiating ribs, there is vent passages and unimpeded thereon.Reinforce convex
Platform, radial radiating ribs, transient equilibrium boss are 3 ° -6 ° drafting angles, and root is with braking disk body at R3-R5 fillets.Attached drawing is said
It is bright
Fig. 1 is the structural diagram of the present invention front view
Fig. 2 is the structural schematic diagram rearview of the present invention
Fig. 3 is positive two intersection graph of structural schematic diagram of the present invention
In figure label for：It brakes disk body 1, brake area 2, center positioning hole 3, uniformly distributed mounting hole 4, reinforce boss 5, the first diameter
To the radial fan-shaped radiating ribs transient equilibrium boss 7 of plate radiating ribs 6, second, third radial plate-like sector combination radiating ribs 8, mistake
Cross balance boss 9.
Specific implementation mode
The present invention is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, the present invention relates to a kind of brake disc of high-speed train-wheel disc, including braking disk body 1, brake area 2, in
Heart location hole 3, uniformly distributed mounting hole 4, reinforcement boss 5, first the 6, second radial fan-shaped radiating ribs transition of radial plate-like radiating ribs are flat
Weigh boss 7, third radial plate-like sector combination radiating ribs 8, transient equilibrium boss 9.It is characterized in that：The high-speed train braking
1 center positioning hole 3 of disk body is located on brake assembly device, and by uniformly distributed mounting hole 4 by being bolted, uniformly distributed mounting hole 4 divides
It is distributed in and reinforces on boss 5.It is radiated by radial radiating ribs by the heat generated in 2 friction process of brake area, generation
Vibrations pass through 9 eliminations of transient equilibrium boss.With good heat dissipation effect, severity of braking is high, and running under braking is steady, safety and effectiveness
Strong advantage.
The present invention using when to reinforce boss 5 be that the coupled radial radiating ribs tangent line of ellipse is connected.Reinforce boss 5
It is uniformly distributed, there is mounting hole 4 thereon.The heat generated in 2 friction process of brake area is radiated by radial radiating ribs, radial
Radiating ribs include the first radial plate-like radiating ribs 6, the second radial fan-shaped radiating ribs 7, third radial plate-like sector combination radiating ribs
8。
All radial direction radiating ribs are uniformly distributed at 7.5 °, and the second radial fan-shaped radiating ribs 7 are R200-R210 sectors.First radial plate
6 second radial direction sector radiating ribs 7 of shape radiating ribs uniformly distribute alternately at 15 °.Third radial plate-like sector combines radiating ribs 8 by 2
The first radial plate-like radiating ribs of group（8-1）2 group of second radial fan-shaped radiating ribs（8-2）And reinforce boss（8-3）Composition, it is fabric
On Moving plate body.
Transient equilibrium boss 9 is evenly distributed at 60 ° in a radial plate-like radiating ribs 6, by vent passages（9-1）, reinforce boss 9,
Radial radiating ribs（9-2）Composition.Transient equilibrium boss 9 is 3 ° -6 ° drafting angles, and root is justified with braking disk body 1 at R3-R5
Angle.
The present invention using the above structure more preferably solve high-speed train braking during generate be higher temperature and it is larger
Vibrations have the advantages that good heat dissipation effect, severity of braking are high, reduce vibrations, running under braking steadily and brake safe performance height etc. one
Kind brake disc of high-speed train-wheeling disk structure.
