Description
Technical field
The utility model relates to rail vehicle braking technical field, particularly relates to a kind of rail vehicle brake disc sheet, dynamic combined type is prevented sticking up axle-mounted brake disk and assembling method.
Background technique
Train running speed is when more than 120km/h, and 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.
Brake disc is the critical component that train momentum can be changed into heat energy by dish, and the braking disk body developed both at home and abroad comprises: cast iron disk body, forged steel disk body, cast steel disk body, aluminum matrix composite disk body, C/C composite material disk body.Steel disk body possesses skills, and degree of normality is high, cost is low, be suitable for the wide feature of velocity range, and the quick and train of high-speed motor train unit of developed country is widely used abroad.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.The structure of brake disc disk body is divided into two kinds, integrated type and split type.Unitary tray body self constraint is comparatively large, and the stress that its internal detent produces is large, but disk body axial deformation is little; The structural constraint of split type disk body self is little, and the stress that its internal detent produces is little, but disk body axially buckling deformation occurs.After disk body generation warpage, brake lining pressure distribution will be caused uneven, and cause the fire damage of brake lining abnormal wear and aggravation disk body card, cause brake lining to be changed frequent, increase operation cost, reduce the service safety of brake disc.
In addition, when installing brake disc, that brake disc is enclosed within wheel hub, when changing brake disc just need brake disc to take out along axle axial, because wheel hub is also provided with other mechanisms or device, these mechanisms or device are the obstacles of dismounting brake disc, have to first these mechanisms or device be pulled down during dismounting brake disc, therefore, the replacing of existing brake disc is very complicated.
People perhaps can expect adopting the mode of folding to go to address this problem, but the brake disc disk body after assembling is when High Rotation Speed, and the joining place of folding disk body can turn up again, axial buckling deformation.Therefore, possess the brake disc disk body changing convenient and anti-sticking up property is problem demanding prompt solution simultaneously.
