To unlock rail when, retaining mechanism with unlock rail cooperation, by move retaining mechanism it is vertical upwards, move downward, complete unlock,
Locking.
Such as Fig. 1-13, specific embodiment is described below.
A kind of gauge-changeable bogie wheel of subdivision gauge to retaining mechanism, including axle box, locking arm, fixing and locking mechanism,
Move retaining mechanism；The locking arm is connect by threaded hole with end face driving mechanism, and the fixing and locking mechanism passes through bolt
Be installed on the end face of axle box, the movement retaining mechanism and locking arm, fixing and locking mechanism coordinate, by it is vertical downwards, to
On movement realize unlock, locking.
The axle box includes top axle box cover 1-1 and lower part axle box pedestal 1-2, passes through single stage suspension and bogie frame phase
Even, the axle box end face is useful for taking turns installs threaded hole 1-3 to the lock tube that retaining mechanism is installed, and the end face of lower part axle box pedestal adds
Work, which has, opens that there are one pilot hole 1-2-2, the pilot hole 1-2-2 to be used on limited block 1-2-1, the limited block 1-2-1
Vertical guiding and circumferential limit.
The locking arm 2 is symmetrically installed before and after becoming well-behaved truck journal box bilateral, and locking arm 2 includes locking slot 2-1；Lock
Tight slot 2-1 tooth pitches are consistent with the tooth pitch of closing piece 5-1, and when locking slot 2-1 is engaged with closing piece 5-1, wheel is in locking state；Locking
Be machined with altogether on arm 2 five sections of locking slots 2-1, five sections of locking slot 2-1 from inside to outside corresponding gauge be 1676mm,
1520mm、1435mm、1372mm、1067mm；The locking arm 2 can only do transverse movement with end face driving mechanism.
The locking arm 2 only engages at locking slot 2-1 with closing piece 5-1, i.e. locking slot 2-1 is the locking section of locking arm 2,
Remaining position is unlock section, and when closing piece is located at unlock section, wheel is in the unlocked state, completes to become with rule driving rail cooperation is become
Rule.
The fixing and locking mechanism includes lock tube 3, key lid 4；Guide hole 3-2 and key slot 3- are machined on the lock tube 3

Ring is for preventing the booties such as external dust, fine particle from entering axle box.
The unlock lifting lug 6-2 is perpendicular by the downward pulling force of unlock track when the end face retaining mechanism unlock of the subdivision gauge
It directly moves downward, the locking spring 8 is compressed at this time, and after the completion of gauge changing, the unlock lifting lug 6-2 is in the locking spring
Return, the end face retaining mechanism locking of the subdivision gauge are moved under 8 resilient force straight up.
There are two the key 5 is total, described two keys 5 are located at the hole that key slot 3-3 is assembled into key lid 4
In, described two keys 5 can vertical sliding in the hole；Described two keys 5 are respectively fixedly connected two in the trapezoidal hammerlock 7
End, 7 lower end of trapezoidal hammerlock are connected with unlock pull rod 7.
The closing piece 5-1's is preferably shaped to tooth form.
The shape of the unlock guide rod 6-1 and the shape of end cap locking pilot hole 1-2-2 match, the unlock
Guide rod 6-1 vertical can only be slided in end cap locking pilot hole 1-2-2.
Now by taking gauge-changeable bogie is from the conversion process that standard gauge 1435mm is converted into broad gage 1520mm as an example, in detail
Illustrate the specific implementation mode of the present invention.
Step 1：Gauge-changeable bogie enters the mating orbital transfer area domain in ground, and the unlock lifting lug moved in unlocking mechanism passes through
The introducing section for unlocking rail introduces unlock rail；
Step 2：Cooperation of the unlocking mechanism by lifting lug and unlock rail is moved, it is vertical downwards with the decline of unlock rail rail surface
Movement completes unlock until being detached with the locked groove on locking arm；
Step 3：Locking arm slides axially together along wheel shaft with sliding shaft sleeve and wheel and completes gauge changing, moves at this time
Unlocking mechanism does longitudinal horizontal movement along the horizontal segment of unlock rail with vehicle, vertical motionless；
Step 4：Movement unlocking mechanism is moved upwards with the rising for unlocking rail rail surface is vertical, is made new on closing piece and locking arm
The corresponding locked groove of gauge enters engagement, and wheel pair is made to be locked at new gauge position with wheel shaft.
The above is the preferred embodiment of the invention, does not limit the present invention with this.
