Description
Technical field
The utility model relates to the wheel dress braking of rail vehicle, and particularly relating to a kind of rail vehicle combined type, anti-to stick up wheel brake disk mounted.
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.
Summary of the invention
It is brake disk mounted that the utility model provides a kind of rail vehicle combined type to prevent sticking up wheel, first the utility model can effectively prevent from taking turns the outer peripheral axial buckling deformation of brake disk mounted disk body, and then improve the convenience of the brake disk mounted mounting or dismounting of wheel further, solve the new axial buckling deformation because improving the disk body that mounting or dismounting convenience brings simultaneously.
The utility model adopts following technological scheme:
It is brake disk mounted that a kind of rail vehicle combined type described in the utility model prevents sticking up wheel, comprise the T-shaped pin being located at rail vehicle wheel both sides and the brake disc disk body be fixedly connected with rail vehicle wheel both sides respectively, the inner side of brake disc disk body is connected to flange, on brake disc disk body, circumference is evenly equipped with wide radiating fin and narrow radiating fin, wide radiating fin and/or narrow radiating fin are provided with T-slot, and described T-shaped pin embeds in corresponding T-slot.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model adopts T-shaped pin, T-slot and is connected, and effectively prevent the especially outer peripheral axial buckling deformation of disk body of the brake disk mounted disk body of wheel.
T-shaped pin is fixedly connected on rail vehicle wheel, simultaneously, T-shaped pin embeds T-slot, rail vehicle wheel is locked by T-shaped and strains at brake disc disk body, T-shaped pin effectively balances the stress producing the axial buckling deformation of brake disc disk body to the stretch-draw of brake disc disk body, thus effectively prevent the axial buckling deformation of the brake disk mounted disk body of wheel.
(2) the utility model is easy to maintenance, is convenient to change, and component interchangeability is good, can prevent again because of easy maintenance simultaneously, change the new axial buckling deformation produced.
The utility model adopts and can be undertaken docking the 2 semi-circular discs connected by folding, during installation or removal, 2 semi-circular discs directly can be taken off from wheel hub, can be described as and take off semi-circular disc from the radial direction of wheel hub, realize the radial dismounting of brake disc disk body, avoid prior art and can only must to remove other wheel axles of hindering and taking off brake disc disk body the problems such as component in advance from the axial dismounting brake disc disk body of wheel hub and the axial dismounting brake disc disk body caused thus, because radial dismounting of the present utility model does not need other component on first dismounting vehicle wheel shaft, that is: it doesn't matter for brake disc disk body of the present utility model dismounting and other component, therefore, the utility model has easy to maintenance, brake disc disk body is convenient to the advantage changed.
The utility model is that identical 4 semi-circular disc combination are formed brake disc disk body, and this just makes can be general between each semi-circular disc, and therefore, of the present utility model have fine component interchangeability.
Although the utility model adopts semi-circular disc combination to form brake disc disk body, can well solve easy to maintenance, be convenient to change, the problem of component interchangeability, but there is butt joint in brake disc disk body, brake disc disk body is caused to occur new weak link at butt joint place, there is new warpage in the end of semi-circular disc, for this new problem, the utility model adopts and arranges boss (boss protuberance) and radial groove respectively at the two end part of semi-circular disc, boss is embedded radial groove, disc stitching portion is made to keep intensity, imbeding relation simultaneously between the boss at disk body splicing seams place and radial groove, the end of 2 semi-circular discs is interacted, be enough to offset the stress producing the new warpage in semi-circular disc end.
The wide radiating fin of combined type described in the utility model adopts the structure identical with wide radiating fin and size, can the replacing of convenient brake disc disk body and maintenance.
