Description

A kind of brake disk mounted disk body of high heat capacity SiCp/Al composite wood material wheels
Technical field
The present invention relates to field of urban rail more particularly to a kind of dress brakings of high heat capacity SiCp/Al composite wood material wheels Disk disk body.The disk body uses casting and forming, is suitable for speed 140km/h municipal rail trains below and Rapid freight train.
Background technology
Foundation brake parts of the brake disc as rail transit train play in terms of the safe operation for ensureing train Vital effect.As " energy conservation and environmental protection " is increasingly by the extensive concern of countries in the world, Lightweight Technology is also answered extensively Use the industry-by-industry field to involve the interests of the state and the people.The lightweight of track train is reducing energy consumption, is saving traction kinetic energy, drop Low train operation expense etc. is of great significance, and especially reduces the component weights such as brake disc and brake lining, can obviously reduce The unsprung weight of bogie improves the dynamic performance of train.
Aluminum matrix composite brake disc is small with density compared to traditional steel material brake disc, specific strength and specific stiffness are high, The series of advantages such as coefficient of thermal expansion is small, good heat conductivity and excellent wear-resisting property;And with C/C fibrous composite systems Compared to having preparation process relatively easy, the advantages such as manufacturing cost is low become new for Moving plate, ceramic matric composite (CMC) The preferred disc material of generation rail transit train brake rigging.It is substituted using aluminum matrix composite brake disc traditional Steel material brake disc, it is possible to reduce the 30~50% of brake disc weight.
For steel brake disc in braking, along with apparent brake squeal, while huge braking thermic load makes brake disc Rubbing surface generates very high and non-uniform Wen Sheng, induces and generates hot spot, influences the service life of brake disc.Aluminum matrix composite Superior heat radiation and heat conductivility make the hot spot of its rubbing surface be eliminated, to extend service life while can be significantly Brake oil is reduced, nothing is uttered long and high-pitched sounds.
The service reliability of brake disc depends on material, structure, Forming Quality and the service condition of brake disc.Aluminum-base composite For material compared with steel material, intensity is relatively low, and especially elevated temperature strength is relatively low, so the structure of aluminum matrix composite brake disc is set Meter key is to reduce the Wen Sheng of brake disc and reduces braking thermal stress.In addition, aluminum matrix composite difficult forming, cast-internal Easily generate the casting flaws such as stomata, fire check, shrinkage cavity shrinkage porosity.
Therefore, traditional steel brake disc is replaced using aluminum matrix composite brake disc, light-weighted requirement can be reached, Also it can achieve the purpose that improve durability that there is huge application prospect in low speed train brake disk field.
Invention content
SiCp/Al composite material tensile strengths are relatively low, and especially increasing its intensity with temperature declines comparatively fast, and SiCp/Al is multiple Condensation material is used for brake disc, it is necessary to solve the problems, such as its thermal capacity by the design of rational brake disc structure.Patent of the present invention provides The brake disk mounted disk body of a kind of high heat capacity SiCp/Al composite wood material wheels (hereinafter referred to as disk body), the disk body have thermo parameters method Uniformly, high heat capacity, axially free warpage, radial the features such as freely stretching.
Technical solution is used by patent of the present invention solves its technical problem:A kind of high heat capacity SiCp/Al composite materials Brake disk mounted disk body is taken turns, structure is by drag ring (1), high plate muscle (2), connecting pole (3), short plate muscle (4), positioning column (5), spiral shell Keyhole (6), locating slot (7) composition.Disk body material is the particle reinforced aluminium-based composite wood of SiC particulate content 10wt%-20wt% Material.The drag ring (1) of disk body uses big thickness and trapezoid cross section, and material distribution is more reasonable, improves temperature field in disk body Distributing homogeneity, thermal capacity higher;Disk body uses radially-arranged high plate muscle (2) and short plate muscle (4), so that disk body is had good Ventilation effect and the rigidity of structure, while the radial section of high plate muscle (2) is "convex" shaped, reduces the pact to disk body axial deformation Beam.
The present invention has the following advantages that compared with prior art:
Disk body involved in the present invention uses SiCp/Al composite materials, and compared with traditional steel brake disc, quality is lighter, system Dynamic nothing is uttered long and high-pitched sounds;
For disk body involved in the present invention using the Counter-gravity Mould Filling under pressure effect, disk body Forming Quality is more preferable;
The drag ring of disk body involved in the present invention uses big thickness and trapezoid cross section, compared with equal thickness drag ring with material point Cloth is more reasonable, in disk body thermo parameters method evenly the characteristics of;
Disk body involved in the present invention uses radially-arranged high plate muscle and short plate muscle, while the radial section of high plate muscle is "convex" shaped makes disk body have good ventilation effect and the rigidity of structure, reduces the constraint to disk body axial deformation.
