ِDescription: |
The Y25-Lsd1 is a standard UIC-ORE bogie, designed for freight wagons running
with speeds of up to 120km/h, the gauge of 1435mm and the load of 22.5t. The
bogie consists of wheel set, axle box, suspension, bogie frame, bogie brake,
load proportional device and etc.
The bogie frame of Y25-Lsd1 is a welded fabrication with the character of high construction speed and
low unsprang mass. By adopting spherical surface pivot bearing, the contact area
between the pivot bearings of bogie and car body is enlarged, the load is
equably distributed, and the ability of delivering longitudinal and transversal
force is strengthened, and the ability of delivering longitudinal and
transversal force is strengthened.
By adopting suspension of two levels stiffness, the vertical stability of tare wagon is improved, so
both of the tare wagon and laden wagon are with excellent dynamic performance.
By adopting Lenoir devices, the requirement for different damping force of tare
and laden wagon is satisfied preferably.
By adopting elastic side bearer, the hunting motion stability of bogie is improved. By adopting block
brake, acts on both sides of each wheel, the brake efficiency is improved and
the block wear is reduced. By adopting weight device, the automatic adjustment
of brake force of tare and laden wagon situation is achieved.
