Abstract
A kind of EMU axle-mounted brake disk drag ring disassembly mechanism, it is characterised in that：Including support element, compressing member and fastening nut, the connecting rod on support element belongs to half-thread bar, and compressing member is a bending plate, and half-thread bar passes through the threaded hole of compressing member to be locked by fastening nut.Ensure after the disassembly mechanism of the utility model is light, simple, easy to operate, while multiple spot is symmetrically installed, when extruding by separation member uniform force, not damaged.Because brake disc belongs to the component that mounting hole has circle symmetrical structure, drag ring, hub quick separating may be implemented using the structure, and ensure that brake disc connecting portion is not damaged, repair and maintenance cost has been saved in the final flaw detection for realizing brake disc.
Description
Technical field
The utility model is related to rail vehicle parts disassembly mechanisms, are torn open more particularly, to a kind of axle-mounted brake disk drag ring
Release mechanism.
Background technology
During overhaul of train-set, needed when necessary to axle-mounted brake disk hub connecting flange root（Drag ring connects with hub
At conjunction）Carrying out flaw detection is carried out, crackle is checked for.It needs to detach brake disc drag ring with wheel hub before inspection.In reality
In operating process, occur because contact surface corrosion, drag ring fitted position are because high temperature deformation leads to not detach, if without reasonably tearing open
Mode is unloaded, brake disc will scrap to cause significant wastage.
Utility model content
The purpose of this utility model is to provide a kind of disassembly mechanism for contributing to brake disc drag ring to be detached with wheel hub, realizes
Hub connecting flange root（Drag ring and hub joint）Carrying out flaw detection.Asking for drag ring and hub can not be detached by solving
Topic, to ensure that the normal flaw detection work of hub, saves maintenance expense.
To achieve the above object, the utility model provides a kind of EMU axle-mounted brake disk drag ring disassembly mechanism, special
Sign is：Including support element, compressing member and fastening nut, the connecting rod on support element belongs to half-thread bar, and compressing member is a folding
Bent plate, half-thread bar pass through the threaded hole of compressing member to be locked by fastening nut.
The support element half-thread bar is located at the centre of compressing member upper surface and support element lower surface distance.
After the disassembly mechanism of the utility model is light, simple, easy to operate, while multiple spot is symmetrically installed, when extruding, ensures quilt
It is separation member uniform force, not damaged.It, can be real using the structure because brake disc belongs to the component that mounting hole has circle symmetrical structure
Existing drag ring, hub quick separating, and ensure that brake disc connecting portion is not damaged, the final flaw detection for realizing brake disc is saved
Repair and maintenance cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is utility model works state diagram.
Specific implementation mode
Referring to Fig.1, the utility model includes support element 1, compressing member 2 and fastening nut 3, the connecting rod category on support element 1
In half-thread bar, compressing member is a bending plate, and half-thread bar passes through the threaded hole of compressing member 2 to be locked by fastening nut 3, described
Support element half-thread bar be located at the centre of compressing member upper surface and support element lower surface distance, so that drag ring 5, hub 4 is more easy to
In separation.
With reference to Fig. 2, which, which is suitable for mounting hole, has the component of circle symmetrical structure, when mechanism is installed, support element
Stationary plane be located inside, compressed with 4 surface of hub, compressing member stationary plane holds out against with drag ring 5, support element 1 and by separation unit
The direction of motion of part hub 4 is consistent, and compressing member 2 is consistent with 5 direction of motion of drag ring, while symmetrically being pacified using multiple disassembly mechanisms
Dress, rotational fastener nut pushes compressing member successively in order, realizes that drag ring 5, hub 4 are quickly divided eventually by interaction force
From.
