Abstract
The utility model discloses a top surface support type radial device, belonging to the technical field of railway rolling stocks and machinery. The top surface support type radial device comprises two U-shaped auxiliary frameworks and two cross connecting rods, wherein the U-shaped auxiliary framework is formed by connecting two L-shaped auxiliary framework bodies through a connecting plate and then assembling with a bearing adapter through a connecting piece. The top surface support type radial device is economized and has light weight, thereby effectively reducing the sprung weight and being beneficial to promoting the mechanical property of a bogie; meanwhile, the dead weight of the whole vehicle is reduced, and the vehicle bearing capacity is improved; moreover, only the bearing adapter worn to the limit is needed to be replaced in maintaining station and depot without replacing the whole U-shaped auxiliary frameworks, thereby saving the maintenance cost. The top surface support type radial device is suitable for a top surface support type bogie.
Description
Affiliated technical field
The utility model relates to the railway freight traffic device, and especially the bogie truck of railway truck belongs to rolling stock and field of mechanical technique.
Background technology
At present, roller bearing adapter stabilizer bar owing to have radially device, thereby has been obtained good effect on aspect reducing wheel-rail force, reduce wheel-rail wear and prolonging service life of wheel, track when the commentaries on classics K7 type bogie truck that adopts by my company's development.But this radially installs and adopts the secondary framework of its integral type U-shaped, and inconvenience to some extent when the section maintenance of station must integral replacing to the secondary framework of the U-shaped that wears away limit, thereby has increased the cost of overhaul; Simultaneously this radially to install deadweight bigger.
The utility model content
In order to solve the existing radially above-mentioned deficiency of device, the utility model provides a kind of and convenient maintenance, reduces the cost of overhaul and the lighter radially device of deadweight.
The technical scheme that its technical matters that solves the utility model adopts is: the end face support type radially installs, comprise the secondary framework of two U-shapeds and two cross connection bars, the secondary framework of U-shaped is connected, assembles through attaching parts with adapter through connecting panel by two L shaped secondary framework bodies.
The beneficial effects of the utility model are that lighter weight can effectively reduce unsprung weight, helps promoting the bogie truck mechanical property; Reduce the car load deadweight simultaneously, improved the vehicle load-carrying capacity; And this new structure need only be changed the adapter that wears away limit when the section maintenance of station, and need not change the secondary framework of whole U-shaped, has saved the cost of overhaul.
Description of drawings
Fig. 1 is the utility model overall structure scheme drawing (birds-eye view);
Fig. 2 is the secondary framework partial enlarged drawing (lower right corner part) of U-shaped among Fig. 1;
Fig. 3 is the assembled relation figure of bogie side frame, adapter and rubber metal pad.
Parts and numbering among the figure:
The secondary framework of 1-U shape, 2-pipe link, 3-pin joint spare, 4-connecting panel, the secondary framework body of 5-L shape, 6-adapter, 7-attaching parts, 8-bogie side frame, 9-rubber metal pad.
The specific embodiment
Below in conjunction with embodiment the utility model is further specified.
As Fig. 1-3, the end face support type radially installs, and comprises the secondary framework 1 of two U-shapeds and two cross connection bars 2, and the secondary framework 1 of U-shaped is connected, assembles through attaching parts 7 with adapter 6 through connecting panel 4 by two L shaped secondary framework bodies 5.
The pipe link 2 of two secondary frameworks 1 of U-shaped and two intersections is sold fitting 3 and is connected, and suit bogie side frame 8 on the secondary framework 1 of former and later two U-shapeds is equipped with rubber metal pad 9 between bogie side frame 8 and the secondary framework 1 of U-shaped.End face by adapter 6 bears weight.
Claims (1)
1. an end face support type radially installs, comprise the secondary framework (1) of two U-shapeds and two cross connection bars (2), it is characterized in that the secondary framework of U-shaped (1) is connected, assembles through attaching parts (7) with adapter (6) through connecting panel (4) by two L shaped secondary framework bodies (5).
