Description
Technical field
It the utility model is related to rolling stock manufacturing technology, and in particular to axle box link.
Background technology
With China railways towards at a high speed, overload direction carry forward vigorously, the travel safety of railway train and operation are flat
Stability problem is but than more prominent.Security and stationarity for the railway locomotive that draws whole train operation is with regard to even more important.
Draw-gear of the axlebox rod as locomotive, is the critical component for connecting locomotive axle babinet and locomotive bogie, carries transmission machine
The tractive force of car or the important function of brake force.When locomotive operation, locomotive axle box is known from experience to be produced respectively relative to the framework of locomotive
The displacement in a direction, this requires the axlebox rod being connected between axle box and framework can be realized between axle box and framework
In the elastic connection of all directions, while the bullet for also requiring axlebox rod to be formed with the journal box spring being arranged on axle box
Property positioner longitudinal direction (along locomotive operation direction), laterally (perpendicular to locomotive operation direction) and it is vertical on can carry
For necessary rigidity value, to ensure the dynamic performance of locomotive operation.
The located lateral rigidity value scope for the axle box that the straight type axlebox rod of the prior art can be provided is relatively narrow, it is difficult to full
The safety of the locomotive continued to develop enough and the needs of even running.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency, there is provided axle box link.
The purpose of this utility model is achieved through the following technical solutions：
Axle box link, including the assembling of axle box, stent, axlebox rod, journal box spring, side block and Vertical Vibration Reduction
Device, stent are installed on axle box, and side block assembling is rack-mount, and stent is installed on axle box body side surface, is also set up on stent
There is vertical damper, axlebox rod is installed on the end of axle box, and journal box spring is installed on the right side of axle box, axlebox rod two
Respectively there is a rubber ball-shaped joint at end.
Rubber ball-shaped joint includes rigid central spindle and drag link body, and drag link body is provided at both ends with rubber sleeve, and rigid central spindle sets
Put inside rubber sleeve, rubber sleeve and rigid central spindle are consolidated.
Connection screw thread is provided with the inside of rubber sleeve.
The upper and lower ends of rigid central spindle are both provided with mounting hole.
The utility model has following beneficial effect：
The utility model is designed reasonably, it is easy to use, by rationally designing elastomer and elasticity inside elastic joint
The arrangement in joint, it is possible to achieve each more preferable matching to locating stiffness value to axle box, so as to improve locomotive entirety
Dynamic performance.
Brief description of the drawings
Fig. 1 is the assembling structure schematic diagram of the utility model；
Fig. 2 is the structure diagram of the utility model.
Embodiment
The utility model will be further described below with reference to the accompanying drawings：
As depicted in figs. 1 and 2, axle box link, including axle box 1, stent 2, axlebox rod 3, journal box spring
4th, side block assembling 5 and vertical damper 6, stent 2 are installed on axle box 1, and side block assembling 5 is installed on stent 2, and stent 2 is pacified
Mounted in 1 side of axle box, vertical damper 6 is additionally provided with stent 2, axlebox rod 3 is installed on the end of axle box 1, axle box
Spring 4 is installed on the right side of axle box 1, and respectively there is a rubber ball-shaped joint at 3 both ends of axlebox rod.
Rubber ball-shaped joint includes rigid central spindle 7 and drag link body 10, and drag link body 10 is provided at both ends with rubber sleeve 9, rigidity
Mandrel 7 is arranged on inside rubber sleeve 9, and rubber sleeve 9 and rigid central spindle 7 are consolidated.
The inner side of rubber sleeve 9 is provided with connection screw thread 8.
The upper and lower ends of rigid central spindle 7 are both provided with mounting hole 11.
Rubber is consolidated on metal core axle by way of vulcanization, axlebox rod be located at bogie frame and axle box it
Between, working space requirement is stringent, it is necessary to the interior matching for realizing axlebox rod Longitudinal stiffness and transverse stiffness in a limited space, and
Need to possess enough bearing capacitys.Pull rod longitudinal rigidity is generally provided by the elastomeric radial of rubber in elastic panel nodes, and horizontal
To rigidity on rubber packed node mainly by cushion elastic deformation provide, while in node rubber sleeve elastic deformation
Also provide fraction rigidity；And rubber arthrosis node is then provided by the deflection of rubber in node and axial elastic deformation completely.
The main function of axlebox rod can provide certain torsion and deflection to transmit the longitudinal force and cross force of locomotive
Rigidity, to adapt to axle box relative to each to movement of framework.
