Abstract
The utility model belongs to the technical field of parts for railway catenary working cars and particularly relates to a wheelset axle box hanging device which is capable of solving the problem that a conventional wheelset axle box hanging device is incapable of meeting the use requirements. The wheelset axle box hanging device comprises a thread seat and a hanger rod, wherein the thread seat is connected with a hanger seat at an underframe of a car body; a through hole is arranged in the thread seat in the axis direction; the hanger rod comprises an upper stage body, a lower stage body and a connecting segment; the upper stage body can penetrate through the through hole of the thread seat and be erected on the thread seat; and the lower stage body is connected with an axle box body through bolts. The wheelset axle box hanging device disclosed by the utility model has the beneficial effects that a thread connection mode is adopted at all parts connected with the hanger seat and the axle box body in the hanging device, so that the hanging device is reasonable in process and convenient for assembling and maintenance; and a connecting structure of the special-shape hanger rod and thread seat is adopted, so that the hanging device is compact in structure, firm in connection, wide in application range and particularly suitable for various types of cars of which the distance between a bogie side frame and an axle box end cover is large or the space between the lower plane of the bogie side frame and the axle box body is narrow and small and the like.
Description
Technical field
The utility model belongs to the technical field of railway contact line Operation Van parts, is specifically related to a kind of the wheel the axle box erecting by overhang.
Background technology
The wheel of domestic existing operation vehicle for contact wire, rail vehicle can reduce two major types to the structure that the axle box erecting by overhang adopts:
1, a kind of be with flap seat be welded on the truck side sill, suspension ring are welded on journal box body; Through bearing pin etc. both are linked, the partition of erecting by overhang and connection must will be taken turns the framework integral body on axle box top is sling and fallen; Manufacturability is poor, assembling and maintenance difficulty.
2, a kind of be with flap seat be welded on the truck side sill, play a hanging board and be installed on the axle box end cap; Remove the axle box bolt of cover; Can take off playing hanging board, if but when the bigger than normal or hydraulic damper mounting means of spacing is special between truck side sill and the axle box end cap, then inapplicable this structure.
Summary of the invention
The goal of the invention of the utility model: solve the existing problem that can not satisfy operating needs to the axle box erecting by overhang of taking turns.
The utility model adopts following technical scheme to realize:
A kind of wheel to the axle box erecting by overhang; It is characterized in that comprising threaded block, suspension rod; Threaded block is connected with the flap seat of car body underframe; Have through hole on the axis direction in the threaded block, but suspension rod comprise can pass threaded block through hole and frame in the last stage body on the threaded block, pass through stage body and linkage section under bolt and the journal box body bonded assembly.
Another preferred version of the utility model: have ellipse hole on the threaded block, stage body also is oval on the suspension rod, the minor axis of the minor axis of the major diameter＞through hole of the major diameter of through hole＞last stage body＞last stage body.
Another preferred version of the utility model: through holding screw threaded block and flap seat are connected after suspension rod and threaded block assembling put in place.
The utlity model has following beneficial effect:
1, threaded connection mode has all been adopted at the position that connects with flap seat, journal box body in the erecting by overhang, makes its technology more reasonable, assembles and overhaul more convenient.
2, the special-shaped suspension rod and the threaded block draw bail of erecting by overhang employing; Compact conformation; It is firm to connect, and Applicable scope is extensive, is specially adapted between truck side sill and the axle box end cap between spacing bigger than normal or truck side sill lower plane and the journal box body all kinds of vehicles such as the space is narrow.
