Description
Technical field
The present invention relates to the cross axle anti-rotation dynamic balancing machines of the foundation brake of rail traffic vehicles, more particularly to brake
Structure.
Background technology
Existing cross axle balance mechanism is in cross axle both sides actuating arm（Working roll is housed on actuating arm --- transmit wedge block
Thrust）Sliding block is added in outside, and sets two platforms in the corresponding position of babinet, in braking process sliding block by platform branch
Support, so as to prevent cross axle because being rotated during stress.On babinet increase platform after weight increase, and the slip plane of platform compared with
It is deep, it is not easy to process.
It being found through retrieval, 101278139 B of patent of invention CN of Faville Lay company disclose a kind of track brake unit,
Relatively traditional cross axle balance mechanism, improvement are：Driving element 22（Namely actuating arm）By rolling friction by shell
Body 10 supports, to be moved on the axial direction of mandrel 16, and mandrel 16 in its front end by the axial guiding of housing 10.From
It is found that it is additionally arranged support roller again on the outside of the working roll of actuating arm in attached drawing, the slip that inside generates when being braked with reducing rubs
Wipe power.
However, the design still relies on traditional sliding platform, and support roller on actuating arm is installed, further increases
Assembly difficulty is added, and has needed to dismantle entire babinet during maintenance and support roller, be inconvenient.
Invention content
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of the prior art, provide the ten of a kind of brake
Word spindle balance mechanism.
In order to solve the above technical problems, the cross axle balance mechanism of brake provided by the invention, including
Cross axle, is set in gap adjustment sleeve, and both sides have actuating arm, working roll is housed on actuating arm；
It is characterized in that：
Cross axle bottom surface is provided with support member, and the corresponding position of babinet is provided with a pair and cross axle axis parallel
Supporting surface, the support member are located at this between supporting surface, and support member is by sliding friction or rolling friction by this to branch
Support face supports.
In order to further solve above-mentioned technical problem, the cross axle balance mechanism of this brake also has following improve：
1st, the support member both sides are fixed with friction plate, and support member is supported by friction plate face supported.
2nd, the friction plate is fixed on the both sides of support member by axis pin.
The 3rd, support roller is installed, the axial line of support roller is vertical with the axial line of cross axle, support in the support member
Component is supported by support roller face supported.
4th, the bottom of box trepanning of supporting surface lower part and equipped with cover board, the cover board is bolted to connection with babinet.
5th, the support member and cross axle are integrated for casting and forming.
6th, the front end face of the cross axle and the locking baffle ring flank of tooth being fixed on gap adjustment sleeve coordinate, and form the flank of tooth
Clutch.
Support member is set to the bottom of cross axle by the present invention, and is supported by the supporting surface of the bottom of box.
Compared to the structure that tradition is supported respectively using both sides actuating arm, the present invention program only needs a support member, and structure is more
Simply.The support member is set to the bottom of cross axle, takes full advantage of the inner space of the bottom of box, and cover by opening
The friction plate or support roller that plate can be supported on component are overhauled and are safeguarded.Due to eliminating the sliding block of actuating arm both sides
With babinet upper mounting plate, therefore make brake structural more compact, process and assemble and is more convenient.In product release of brake, branch
Support part part slides between a pair of of supporting surface of the bottom of box, prevents cross axle from deflecting, structure is safe and reliable.
In addition, the present invention also protects a kind of brake, it is characterised in that：Include claim 1-7 any one of them
Cross axle balance mechanism.
Description of the drawings

Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described.
Embodiment one
As shown in Figure 1 and Figure 2, the present embodiment brake, including babinet 4, cross axle 1 and gap in babinet 4 adjust sleeve
11, be equipped with lash adjusting device in gap adjustment sleeve 11, cross axle 1 is sleeved on gap adjustment sleeve 11, front end face with it is solid
10 flank of tooth of the locking baffle ring cooperation being scheduled on gap adjustment sleeve 11, forms flank of tooth clutch, the front side of locking baffle ring 10 passes through
Resetting spring 9 is pressed in the rear end face of stop sleeve 8, and due to the elastic force by resetting spring 9, which keeps engagement shape
State, so as to which cross axle 1 and gap be made to adjust sleeve 11 and keep axial static.Stop sleeve 8 is fixed on babinet 4 by split ring 7
It is interior.The wedge block of checking cylinder pushes, and by the working roll output driving power on 1 support arm of cross axle, makes the side in an axial direction of cross axle 1
It marches forward, brake force is exported by gap adjustment sleeve 11 and its internal clearance adjustment mechanism.
In order to ensure that cross axle 1 does not deflect in braking process, the present embodiment is provided with cross axle balance mechanism.Such as
Shown in Fig. 1, which is provided with support member 12 in 1 bottom surface of cross axle, and it is one that support member 12, which with cross axle 1 is casting and forming,
Body.The corresponding position of babinet 4 is provided with a pair of supporting surface 13 with 1 axis parallel of cross axle, and it is right that support member 12 is located at this
Between supporting surface 13,12 both sides of support member are fixed with the friction plate 2 of polyformaldehyde material by axis pin 3, and support member 12 is then led to
2 face 13 supported of friction plate is crossed to support.In braking process, support member 12 is supported face 13 by both sides friction plate 2
Support no matter which direction torsion comes from, makes cross axle 1 all not rotate, so as to ensure the normal work of brake.
For the ease of being overhauled to cross axle balance mechanism.As shown in Figure 1,4 bottom of babinet of 13 lower part of supporting surface is opened
Hole is simultaneously equipped with cover board 5, and cover board 5 is fixedly connected with babinet 4 by hex bolts 6.In this way, cover board 5 can be dismantled, it is convenient to branch
Support part part 12 is overhauled, without disassembling the mechanism in babinet 4.
Embodiment two
The present embodiment is identical with the primary structure of embodiment one, difference lies in the cross axle balance mechanism of brake, props up
Support part part 12 is supported by rolling friction supporting surface 13.Specifically, support roller is installed in support member 12, support roller
The axial line of axial line and cross axle 1 and vertical, support member 12 is supported by support roller face 13 supported.
The setting of support roller can be one either along one row of setting of 1 axial direction of cross axle or along cross axle 1
2 rows of axial direction parallel arrangement, naturally it is also possible to be two side by side.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
Into technical solution, all fall within the present invention claims protection domain.
