Abstract
The utility model discloses a kind of locomotive axle boxes, using the split type axle box of axlebox rod distal end arrangement, reduce height of the spring holder apart from rail level, ensure that locomotive height meets the height clearance of narrow gage locomotive, improve the natural bow of compact locomotive single stage suspension, ensure stable and repair and maintenance the high efficiency of locomotive.The cost of the axle box manufacturing is not limited, reduced by extraneous size.Suitable for low clearance, multipart compact locomotive.
Description
Technical field
The utility model is related to locomotive axle box body technique fields.
Background technology
The CKD9D type locomotives in my company outlet South Africa created the power of global narrow gauge diesel locomotive most, narrow gauge
Locomotive has greater difference compared with standard gauge gage locomotive in overall dimensions of a car, and additional gauge limitation, wheel footpath is smaller, and vehicle height drops naturally
Low, bogie highly decreases, and traditional axle box can not effectively transmit the required longitudinal force of low clearance bogie,
So as to be not achieved good dynamic performance, gap is too small between additional compact engine truck component, this gives locomotive inspection
It repaiies and safeguards great limitation.
Existing axle box uses the positioning method of duplex pull rod, and the spring base of axle box both sides is respectively in the upper of axle center
Side, lower section are equipped with axlebox rod mounting hole, and axle box is internally provided with bearing bracket.Axle box overall surface has reinforcing rib and loss of weight
Mouthful, longitudinal force is provided for locomotive, ensures locomotive stable operation.But this axle box has significant drawback：
1) spring base influences locomotive operation stability apart from rail level excessive height.
2) monoblock type axle box locomotive inspection and repair, safeguard when limited too much by extraneous size.
3) manufacture of traditional axle box has several kinds of axle box assemblings, considerably increases manufacture cost because design needs.
Invention content
The technical issues of the utility model solves is to provide a kind of suitable for low clearance bogie, compact locomotive, side
Just the split type axle box of Maintenance and Repair ensures the locomotive axle box of locomotive operation stability and repair and maintenance high efficiency.
The technical solution adopted in the utility model is a kind of locomotive axle box, and axle box is equipped with the spring being arranged symmetrically
Disk mounting base and axlebox rod mounting hole, axlebox rod mounting hole are located on the outside of spring holder mounting base, axlebox rod mounting hole and
Spring holder mounting base keeps sustained height, and the lower section at axle box center is equipped with axle box bottom plate.
The spring holder mounting base is two, is arranged symmetrically along axle box center line, and the axial direction pull rod mounting hole is two groups,
Two groups of axial direction pull rod mounting holes are arranged symmetrically along axle box, and every group of axial direction pull rod mounting hole is two.
The beneficial effects of the utility model are split type axle box of the axle box using axlebox rod distal end arrangement, are reducing bullet
While height of the spring disk apart from rail level ensures that locomotive height meets the height clearance of narrow gage locomotive, compact locomotive one is improved
It is the natural bow of suspension, ensures stable and repair and maintenance the high efficiency of locomotive.It does not limited by extraneous size, reduce axis
The cost that case is manufactured.Suitable for low clearance, multipart compact locomotive,
Description of the drawings
Fig. 1 Novel shaft babinet schematic diagrames.
Fig. 2 Novel shaft babinet stereoscopic schematic diagrams.
In figure label for：1- axle box bottom plates, 2- spring holder mounting bases, 3- axlebox rod mounting holes.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Traditional axle box spring holder is above axlebox rod, if be mounted on the engine truck, axlebox rod seat
With vertical being superimposed of 2 position of spring holder mounting base, the height of bogie entirety has been raised.It can to turn an axle box height lift
Height can not influence locomotive operation stability, therefore, change the position of spring holder by the gauge height of compact locomotive；It abandons
Integrated shaft babinet, to ensure the convenience of running part repair and maintenance；Consider the demand for using and installing, reduce production
Cost.The utility model suitably lengthens the longitudinal length of axle box, in this way under the premise of bogie entire length is not influenced
Height of the spring holder apart from rail level is reduced, axlebox rod mounting hole 1 moves to the side of spring holder mounting base 2 therewith
As shown in Figure 1, the locomotive axlebox rod of the utility model by axlebox rod seat by the lower section of spring holder mounting base 2
2 side of spring holder mounting base is moved to, reduces the height of axle box entirety so that entire locomotive can pass through narrow gage locomotive
Height clearance, it is ensured that locomotive dynamics performance.After axlebox rod moves to spring disc side, the convenient of production installation is improved
Property；Using split type axle box, the high efficiency of compact locomotive inspection and repair maintenance is further improved.
