A kind of gauge-changeable bogie gauge changing method of end face drive-type realizes that the transformation of gauge, method include mainly
Following steps:
Step 1:The crankcase cover positioning centering body realizes the located lateral centering of gauge-changeable bogie;
Step 2:Support truck journal box makes axle unload;
Step 3:The wheel unlocks retaining mechanism, and the end face driving mechanism can slide axially along axle;
Step 4:Pushing and pulling the end face driving mechanism makes wheel slide into pair to match with institute gauge changing along axle
Answer position;
Step 5:The wheel locks retaining mechanism, and the end face driving mechanism is connected with axle box, completes gauge changing.
The positioning centering of gauge-changeable bogie is by crankcase cover positioning centering body and mating ground in step 1
Centering rail cooperation in gauge changing auxiliary device is completed.
The centering rail is installed in the mounting bracket on railway roadbed, is located at the both sides of gauge-changeable bogie.
The unloading of axle is completed by the back-up roller wheel group in mating ground gauge changing auxiliary device in step 2, described
Back-up roller wheel group be made of the roller built in bearing.
Wheel described in step 3 is installed on the end face of axle box retaining mechanism, and unlock rail is by pushing or pulling on wheel to locking machine
The unlock guiding axis of structure makes wheel release between the key and the locking arm of end face driving mechanism of retaining mechanism to engage, to complete
Unlock;The unlock rail is installed in the mounting bracket of axle box side, is located at railway roadbed both sides.
The sliding of wheel is caused by being slid axially along axle by the end face driving mechanism in step 4.
Thrust or pulling force suffered by end face driving mechanism described in step 4 are by mating ground gauge changing auxiliary device
Gauge changing driving rail provide, gauge changing driving rail to the actuating arm of end face driving mechanism apply thrust realize broad gauge to
The transformation of narrow gauge, gauge changing drive rail to apply pulling force to the actuating arm of end face driving mechanism and realize transformation of the narrow gauge to broad gauge.
The gauge changing driving rail is installed in the mounting bracket of axle box side, is located at railway roadbed both sides.
Wheel is in normal lock status to retaining mechanism in step 5, and coupling mechanism force derives from locking spring of the wheel to retaining mechanism,
The locking spring makes wheel be intermeshed the key of retaining mechanism and the locking arm of end face driving mechanism, by end face driving mechanism
Locking opposite with axle box, and then wheel in vehicle travel process is made not change wheelspan.
Now for the conversion process by gauge-changeable bogie between standard gauge 1435mm and broad gage 1520mm, in detail
Illustrate the transform method of gauge.
Step 1:Gauge-changeable bogie enters mating ground gauge changing auxiliary device region, the crankcase cover positioning
Centering roll wheel assembly 18 in centering body contacts centering rail 25 and rolls on, and realizes the positioning pair of gauge-changeable bogie
In;
Step 2:The supporting boot of gauge-changeable bogie lower part proceeds in back-up roller wheel group 21, and back-up roller wheel group 21 supports
Gauge-changeable bogie makes axle unload;
Step 3:Unlock rail 22 of the wheel to the unlock roll wheel assembly 15 of retaining mechanism in 21 outside of back-up roller wheel group is recessed
It is rolled in slot, the position with unlock 22 groove of rail rises, and roll wheel assembly 15 is vertical moves upwards for driving unlock, to driving wheel
The closing piece 11-1 of retaining mechanism is engaged with the releasing of locking arm 5, end face driving mechanism is in the state that can slide axially along axle;
Step 4:Concave slot sports of the drive roller group part 7 of the end face driving mechanism on gauge changing driving rail 24, become
Gauge driving rail 24 slides axially to push or pull on end face driving mechanism along axle;If gauge is transformed to by 1435mm
1520mm, then integrally to axle shaft end sliding, on the contrary then two wheels slide in opposition for end face driving mechanism and sliding sleeve, wheel etc.;
Step 5:Guiding axis 12 is vertical moves downward to the locking spring 14 of retaining mechanism driving unlock for the wheel, to
So that closing piece 11-1 is intermeshed with locking arm 5, by the locking opposite with axle box of end face driving mechanism, gauge changing is completed.
The above is the preferred embodiment of the invention, does not limit the present invention with this.
