Description of drawings
Fig. 1 is the structural representation that the utility model is used for the catch gear of gauge-changeable bogie;
Description of symbols among the figure: axletree 1, wheel 2, wheel hub 3, locating part 4, plain bearing 5, groove 6, jack 7, lock pin 8, linkage pull rod mechanism 9, cross bar 91, short rod 92, long draw 93, hanger 10.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 1, the catch gear that should be used for gauge-changeable bogie, comprise axletree 1, wheel 2 is installed on the axletree 1, on the described axletree 1 locating part 4 is installed, described locating part 4 relatively rotates with axletree 1 and is connected, and limiting wheel 2 is installed along axletree 1 axially movable latching device on the described locating part 4, be connected with the trigger-type tripper on the latching device, described trigger-type tripper utilization becomes the gauge ground installation and triggers release.The catch gear that should be used for gauge-changeable bogie is a relatively independent mechanism, therefore, can very convenient catch gear be keeped in repair and change, do not need the axle box of gauge-changeable bogie is carried out any design and improvement yet, can not increase the volume of axle box, and then bring any inconvenience can for the design of axle box suspension gear yet, this catch gear is not high to the requirement on machining accuracy of catch gear simultaneously, be easy to processing and manufacturing, reliability is also better.
In the above-described embodiment, described latching device and trigger-type tripper can adopt multiple mode, for example, described latching device can be the expansion link that is fixed on the locating part, on expansion link, connect the self adaptation contact by connecting rod mechanism and form described trigger-type tripper, as preferred mode be: described latching device comprises the row of two on the outer circumference surface that is arranged on wheel 2 wheel hubs 3 groove 6, described groove 6 is along the circumferencial direction setting of wheel hub 3, locating part 4 is provided with jack 7, also comprise lock pin 8, one end of lock pin 8 stretches in the jack 7 and can insert in the groove 6, described trigger-type tripper comprises the hanger 10 that can contact with change gauge ground installation, and described hanger 10 links to each other with lock pin 8 by linkage pull rod mechanism 9.The working process of this latching device and trigger-type tripper is as follows: when wheel 2 does not need to become rail, the lower end of lock pin 8 is to insert in the groove 6, at this moment, wheel 2 is pinned by lock pin 8, can't move axially along axletree 1, when wheel 2 arrives when becoming the gauge ground installations, hanger 10 is connected with card rail on the change gauge ground installation, card rail on the change gauge ground installation is divided into and is three sections: first section, the height of card rail constantly increases; Second section, the height of card rail remains unchanged; The 3rd section, the height of card rail constantly reduces, when hanger 10 contacts with first section card rail, hanger 10 is because the increase of card rail height is subjected to application force upwards, this application force is delivered to lock pin 8 by linkage pull rod mechanism 9, lock pin 8 is being driven upward movement, when lock pin 8 leaves groove 6, wheel 2 is in released state, the bottom of lock pin 8 is positioned at jack 7, make the position of lock pin 8 can not depart from, hanger 10 contacts with second section card rail then, the height of this stage card rail remains unchanged, in this process, wheel 2 is under the booster action that becomes the gauge ground installation, wheel 2 is laterally mobile along axletree 1, behind the track that arrives predetermined gauge, the height of card rail is in the 3rd section, has produced downward pulling force, and hanger 10 moves downward under this power effect, thereby driving lock pin 8 by linkage pull rod mechanism 9 moves downward, lock pin 8 is got back in the new groove 6, and at this moment, wheel 2 is pinned by lock pin 8, hanger 10 breaks away from the card rail, thereby gauge-changeable bogie has been finished the conversion of gauge track, and whole process is finished automatically, and latching device and trigger-type tripper are the Purely mechanical structure, whole switching process can be finished fast and effectively, and in addition, the structure of this latching device and trigger-type tripper is very simple, processing and fabricating is all very convenient, so the maintenance with the replacing also very convenient.
Described linkage pull rod mechanism 9 can adopt existing various structure, as long as can realize the purpose that links, as preferred mode be: described linkage pull rod mechanism 9 comprises cross bar 91, cross bar 91 1 ends are provided with short rod 92, the other end is provided with long draw 93, described lock pin 8 is fixed on the termination of short rod 92, and described hanger 10 is fixed on the termination of long draw 93.
In addition, in order to guarantee that locating part 4 does not move with wheel 2 and do not rotate with axletree 1 that described locating part 4 links to each other by plain bearing 5 with axletree 1, and locating part 4 and plain bearing 5 interference fit.
Further, for convenient maintenance and replacing, described locating part 4 is arranged on the outside of wheel 2.The structure of described locating part 4 can be diversified, and for the ease of installing, described locating part 4 is sleeve.The shape of cross section of described sleeve can be circle, and in order to increase the structural strength of sleeve, preferred, the shape of cross section of described sleeve is interior round foreign side.
Moreover described groove 6 can be circular groove, square groove etc., and for the ease of processing, described groove 6 is conical socket usually.
