Abstract
The utility model relates to a pull rod in railway freight car bogie with adjustable, including I section on well pull rod and well pull rod stage II, characterized by: I section on well pull rod and well pull rod stage II connect the end by connecting rod and a connection at the U -shaped of connecting rod one end and constitute, are equipped with at the rod end of I section connecting rod on the well pull rod and take screwed internal thread hole, are equipped with the screw rod that has the external screw thread at the rod end of well pull rod stage II connecting rod, and well pull rod passes through screw rod and screw hole cooperation connection with well pull rod stage II for I section. Its advantage is: fall into two parts with the well pull rod of the unable regulation of original length, fixing dimension through rotatory length of adjusting whole well pull rod, is guaranteed in two parts cooperation back, and the assembly is simple, easy maintenance, has satisfied on -the -spot assembly requirements.
Description
Technical field
The utility model relates to pull bar in a kind of adjustable railway goods train bogie, belongs to railway goods train bogie field of components.
Background technology
Middle pull bar is one of foundation brake rigging critical component in railway truck running part-bogie truck.The effect of foundation brake rigging is the braking force transmitting and amplify brake cylinder, make brake shoe and wheel between the internal friction of bogie truck that produces be converted to external friction power (i.e. braking force) between wheel track, thus make vehicle bear the resistance of working direction, make just to stop in the distance range of regulation at operating vehicle, middle pull bar is then used to the vital part connecting two composite brake beams in foundation brake rigging, braking force well can be delivered on two brake beams, thus the lorry of running is stopped in the distance of safety.
The middle pull bar that current domestic lorry uses is all that in forging integral type, pull bar as shown in Figure 1, all cannot regulate its length.
In forging integral type, pull bar is divided by two ends U-shaped portion to form with middle connecting rod, employing solid forging processes, be connected and fixed at the scene lever composition and floating lever composition time be difficult to ensure floating lever form location dimension, practical set value and theory calls value deviation excessive.
Summary of the invention
The purpose of this utility model is to provide a kind of requirement that can meet pull bar intensity in tradition, rigidity function, can ensure again the comfort feature that site assembly is debugged, pull bar in the adjustable railway goods train bogie met design requirement simultaneously.
The purpose of this utility model realizes with the following methods:
The utility model comprises I section, middle pull bar and II section, middle pull bar, it is characterized in that: the U-shaped connection end that I section, middle pull bar and II section, middle pull bar are connected to connecting rod one end by connecting rod and is formed, screwed internal thread hole is provided with at the rod end of middle pull bar I section of connecting rod, be provided with externally threaded screw rod at the rod end of middle pull bar II section of connecting rod, I section, middle pull bar and II section, middle pull bar are connected by screw rod and tapped bore.
The utility model has the advantages that: in original length cannot being regulated, pull bar is divided into two parts, after two parts coordinate, by rotating the length regulating whole middle pull bar, ensureing fitted position, assembling simple, easy to maintenance, meet site assembly requirement.
Accompanying drawing explanation
Fig. 1 is pull bar foundation brake rigging structural representation in prior art forging integral type;
Fig. 2 is the foundation brake rigging structural representation adopting middle pull bar of the present utility model;
Fig. 3 is middle Tiebar structure schematic diagram of the present utility model;
Fig. 4 is pull bar I segment structure schematic diagram in the utility model;
Fig. 5 is pull bar II segment structure schematic diagram in the utility model.
Detailed description of the invention
As shown in Figure 1, what middle pull bar 1 one end in basic braking device for steering bogie of railway goods train connected is truck dead lever composition 3, what the other end connected is floating lever composition 2, braking force is finally delivered on the brake shoe 5 of brake beam 4, make brake shoe produce friction force to wheel, thus reach the effect of freight car braking.
As shown in Figures 3 to 5, the utility model comprises I section, middle pull bar and II section, middle pull bar, the U-shaped connection end that I section, middle pull bar and II section, middle pull bar are connected to connecting rod one end by connecting rod and one is formed, screwed internal thread hole is provided with at the rod end of middle pull bar I section of connecting rod, be provided with externally threaded screw rod at the rod end of middle pull bar II section of connecting rod, I section, middle pull bar and II section, middle pull bar are connected by screw rod and tapped bore.
As shown in Figure 2, floating lever is first formed 2 positions by middle pull bar 1 of the present utility model before assembly, and size adjusting is good by drawing, then the size that in reality, pull bar needs is measured, I section, middle pull bar and II section, middle pull bar are threaded connection, rotate to the length of the middle pull bar of actual needs, then middle pull bar two ends and truck dead lever composition 3, floating lever composition 2 are linked together, ensure that designing requirement, make equipment adjustment simple, convenient.
