For being connect with railcar body bottom.
Preferably, the rail flat car Wheels group arrangement of the turning smoothly tight turn radius of the utility model, installation cavity are opened
The lid blocked by several nuts is equipped at mouthful.
Preferably, the rail flat car Wheels group arrangement of the turning smoothly tight turn radius of the utility model, taper roller axis
Hold the tapered roller bearing being oppositely arranged for two.
Preferably, the rail flat car Wheels group arrangement of the turning smoothly tight turn radius of the utility model, the rotation axis
It is pierced by from the pedestal bottom and rotation axis bottom is blocked by end cap.
Preferably, the rail flat car Wheels group arrangement of the turning smoothly tight turn radius of the utility model, turning is smoothly
The rail flat car Wheels group arrangement of tight turn radius, pedestal are bolted by upper and lower two bearing blocks and are formed.
The utility model also provides a kind of rail flat car of turning smoothly tight turn radius, including car body, and is located at
Four Wheels group arrangements of vehicle bottom, the Wheels group arrangement are the rail flat car wheel group of above-mentioned turning smoothly tight turn radius
Device.
The beneficial effects of the present invention are:
The rail flat car Wheels group arrangement of the turning smoothly tight turn radius of the present embodiment, is added circle between wheel group and car body
Taper roller bearing, tapered roller bearing large carrying capacity are able to bear the larger axial load that load is applied.Two set side by side
The wheel set can be freely oriented to according to the shape of track, so as to realize with the turning of the smallest turning radius.Save one
As rail flat car when turning to wasted time and naturally turning by electric turntable required biggish turning radius wasted
Place space.
