Description
Technical field
The utility model is related to the technical field of rail vehicle disc-brake, more particularly to a kind of spliced anti-reflex action axle
It is brake disk mounted.
Background technology
China is greatly developing more than 160km/h quick lorry and more than 200km/h EMUs and high ferro train.
It was verified that when train running speed brings up to more than 120km/h, traditional brake shoe-wheel tread braking can not meet row
The requirement of car braking, so the foundation brake mode of quick lorry and train of high-speed motor train unit uses disc braking.
Brake disc is the critical component that train momentum is changed into heat energy by friction energy, present goods train both domestic and external
The most of axle-mounted brake disk used with high-speed railway is monoblock type brake disc, and small part uses spliced split type braking
Disk.Unitary tray body itself constraint is larger, and the stress that its internal detent is produced is big, but disk body axial deformation is small；Split type disk body
The structural constraint of itself is small, and the stress that its internal detent is produced is small, but after multiple braking, disk body outer can occur axial
Buckling deformation.Disk body occurs after warpage, and brake lining pressure distribution will be caused uneven, causes brake lining abnormal wear and aggravation disk body to rub
The fire damage in wiping face, causes brake lining to be changed frequent, increases operation cost, reduce the service safety of brake disc.
Utility model content
Technical problem to be solved in the utility model：Spliced split braking disk body can occur axially to stick up after repeatedly braking
The problem of song deformation.
The technical solution of the utility model：The utility model purpose is the spliced anti-reflex action brake disc structure of offer, with
Axial buckling deformation during overcoming spliced braking disk body under arms.
The purpose of this utility model is achieved through the following technical solutions：Spliced anti-the first disk body of reflex action brake disc 1 and
The outer of two disk body 8 is respectively provided with column radiating ribs 2, column radiating ribs 2 and processes acute angle first, second using the method for turning
Groove 3,7.First groove 3 is located at the outside of column radiating ribs 2 of the first disk body 1 and is open towards disc outer diameter direction, second
Groove 7 is located in the column radiating ribs 2 of the second disk body 8, and cutting opening is towards brake disc center axis.First disk body 1 and the second disk body 8
The opening angle of first, second groove 3,7 in column radiating ribs 2 can be adjusted according to actual requirement.First disk body 1 and
Two disk bodies 8 can realize splicing by the fastening of first, second groove 3,7 in column radiating ribs 2, when the first disk body 1 and
When reflex action deformation occurs for two disk bodies 8, the mating surface of first, second groove 3,7 comes in contact and prevents the first disk body 1 and the second disk
Body 8 continues occur axial buckling deformation, can be realized by the opening angle and fit clearance that adjust first, second groove 3,7
Control to different reflex action deflections.
The technical solution of the utility model is as follows：
A kind of spliced anti-reflex action axle-mounted brake disk, is divided into the first disk body (1) and the second disk body (8) according to structure design；
The disk body is made up of long radiating ribs (4), short radiating ribs (5), drag ring (6) and column radiating ribs (2), it is characterised in that：The
First, be evenly distributed in column radiating ribs (2), column radiating ribs (2) on the outside of the second disk body (1,8) and circumferentially open up first, the
Two grooves (3,7), the first disk body (1) and the second disk body (8) are matched somebody with somebody by rotating dress can make the first groove (3) and the second groove (7)
Realize and fasten；
Circumferential first, second groove (3,7) can be by adjusting on first disk body (1) and the second disk body (8) column radiating ribs (2)
Whole opening angle and fit clearance realize the control to different reflex action deflections.
In above-mentioned spliced anti-reflex action axle-mounted brake disk, the first disk body (1) and the second disk body (8) column radiating ribs (2)
The upper groove of circumference first, second (3,7) uses the first groove (3) in turnery processing, the first disk body (1) column radiating ribs (2) to exist
On the outside of column radiating ribs (2) and it is open towards disc outer diameter direction；Second groove in second disk body (8) column radiating ribs (2)
(7) on the inside of the column radiating ribs (2) and it is open towards brake disc axis direction.
The utility model has the following advantages that compared with prior art：
First groove 3 of the opening towards disc outer diameter, the second disk are processed in column radiating ribs 2 on first disk body 1
Second groove 7 of the opening towards brake disc internal diameter is processed in column radiating ribs 2 on body 8, first, second disk body 1,8 passes through
First, second groove 3, after 7 are spliced, can prevent the first disk body 1 and the second disk body 8 from occurring asking for axial buckling deformation
Topic.First, second groove 3,7 set in column radiating ribs 2 is all on same Radius, so in process can profit
Processed at one time with method for turning, it is not necessary to withdrawing, reduce difficulty of processing and reduce process time.Simultaneously because column
Radiating ribs 2 are in the outer position of first, second disk body 1,8, to the friction radius of first, second disk body 1,8 in braking procedure
The expansion constraint nearby produced is smaller, therefore will not produce excessive stress at first, second groove 3,7 in braking procedure.
The brake disc structure of anti-reflex action structure reduces axial buckling deformation and the braking thermal stress of first, second disk body 1,8, anti-reflex action
Structure design also considers efficient, economic processing method simultaneously.The design can not only improve the service life and peace of brake disc
Full performance, also has obvious social and economic benefits.
