Description
Technical field
The present invention relates to the technical field of disc brake, particularly one is anti-sticks up casting forging Moving plate used for rail vehicle.
Background technique
China is greatly developing motor train unit train and the high ferro train of the heavy rapid heavy-load lorry of the fast rail train in city of more than 120km/h, 160km/h, 21t axle and more than 200km/h.Facts have proved, when train running speed brings up to more than 120km/h, traditional brake shoe-wheel tread braking can not meet the requirement of train braking, so the foundation brake mode of the fast rail train in city, rapid heavy-load lorry and train of high-speed motor train unit all adopts disc braking, the design is also the disc brake adopted.
Brake disc military service operating mode is complicated, bears the coupling in the multiple field of force.This body structure of disk body has nonuniformity, in braking process, cause the uneven distortion of brake disc disk body because temperature variation is uneven, the internal stress that its inner existence is larger, affects the service safety of brake disc and reduces its working life.So done large quantifier elimination to the material of brake disc both at home and abroad, as cast iron disk body, forged steel disk body, cast steel disk body, aluminum matrix composite disk body, C/C composite material disk body etc., wherein use on railway based on cast iron, cast steel, forged steel, cast iron, cast steel are applicable to low-speed vehicle, forged steel is applicable to speed car, the casting forging Moving plate of the design is speed car service, so be applicable to speed car.
In order to adapt to the needs keeped in repair, the structure of brake disc disk body is divided into two kinds, integrated type and split type.Unitary tray body is because of the symmetry properties of himself structure, and make it be out of shape symmetrically under power and hot impact, uniform force is symmetrical, and card abrasion evenly, increase the service life; Split type disk body is because of the asymmetry of himself structure, it is made to be out of shape under power and hot impact uneven, make disk body generation buckling deformation, brake lining pressure distribution will be caused uneven, cause the fire damage of brake lining abnormal wear and aggravation disk body rubbing surface, cause brake lining to be changed frequent, increase operation cost, reduce the service safety of brake disc.Consider us and have employed integrated type brake disc, in addition, current brake disc transmits the single frictional force transmission of the many employings of mode of braking torque, the brake disc that the present invention relates to is then the mechanical force acting in conjunction by frictional force and resilient key, realize the transmission of moment of torsion, homogenization is risen to local stress distribution.
Summary of the invention
Technical problem to be solved by this invention: by the optimization of brake disc structure, reach under power and hot effect, brake disc distortion evenly, thus make brake disc in use, even wearing, stable performance, increase the service life, ensure again feasibility and the stability of technique simultaneously, improve the accepted product percentage of product, reduce costs.
Technological scheme of the present invention: the object of this invention is to provide and a kind of anti-stick up casting forging Moving plate used for rail vehicle, casting brake disc is easy to shaping, and cost is low, but bad mechanical property, shrinkage cavity, the defect such as loose is inevitable, and conforming product rate is low.The shaping complexity of forging brake disc, cost is high, but good mechanical property.Casting forging Moving plate falls between, and solve formation problems, improve product qualified rate, mechanical property is close to the index of forging simultaneously, has both advantages concurrently.
Object of the present invention is achieved through the following technical solutions: one is anti-sticks up casting forging Moving plate used for rail vehicle, comprise hub, disk body one and disk body two, described disk body one and disk body two are formed by flange, friction ring and radiating fin entirety, it is characterized in that: the uniform through hole of described flange circumference; Described radiating fin respectively circumference is distributed on disk body one and disk body two, the apical position of described radiating fin is also provided with to be prevented sticking up button, it is described that anti-to stick up button as a whole with radiating fin, the described anti-button that sticks up radially is offered groove by a side of radiating fin and is formed, and disk body one anti-sticks up to detain to stick up to detain with disk body two anti-and be mutually engaged; The inner side of radiating fin is connected with arc transition between flange; Circumferential uniform trapezoidal groove and through hole in hub; Hub, disk body one and disk body two realize circumference location by resilient key; Hub, disk body one are crossed fastening piece with disk body two-way and are fixedly connected with.
Further, it is trapezoidal groove that cross section is radially offered in described wide type radiating fin side, and the quantity of groove is identical with the quantity of flange circumferential through-hole; Disk body one and disk body two, by the anti-fastening sticking up button lateral grooves, prevent the axial buckling deformation of disk body one and disk body two.
Further, the one according to claim is anti-sticks up casting forging Moving plate used for rail vehicle, and circumferential uniform through hole in hub, its quantity is identical with the number of openings on flange.
The present invention compared with prior art tool has the following advantages:
Trapezoidal groove is radially offered in an anti-anti-side of sticking up button of sticking up casting forging Moving plate disk body one used for rail vehicle and disk body two.Disk body one and disk body two, by the anti-fastening sticking up button side groove, solve the axial buckling deformation problem of disk body one and disk body two; The anti-button that sticks up has anti-sticking up and heat sinking function concurrently, is connected the axial restraint realizing hub, disk body one and disk body two by clamping bolt with nut; Hub, disk body one, disk body two realize circumference location by resilient key, solve braking torque homogenizing and buffer function, guarantee the unimpeded of distinguished and admirable road, make the combined stress of disk body (mechanical stress, thermal stress) distribute quite reasonable, make cooling effect better, this structure makes casting forge and is easy to shaping, reduce forming energy, eliminate casting forging defect, crackle, well verified in deform simulation analysis and actual casting forging process.The design of this brake disc limits the axial warpage of disk body one and disk body two, and the braking service life of brake disc and Safety performance access raising, have obvious social and economic benefits.
