Description
Technical field
The present invention relates to rail vehicle drawing pull bar apparatus field, specially a kind of rail vehicle truck is drawn with traction
Bar.
Background technique
The main connection body of drawing pull bar and bogie transmit between tractive force and brake force and car body and bogie
Various impact forces.Therefore, drawing pull bar is one of the important part that rail vehicle truck uploads graduating power.
In recent years, as the requirement of the rail traffic vehicles speed of service and comfort is higher and higher, in design bogie
When it is light-weighted to its spatial constructional dimensions and weight requirement be also increasingly stringenter, the bulk of bogie is also more and more narrower
It is small, it is more and more compacter, be difficult to have larger space to go installation drawing pull bar, be easy to appear can not entrucking or on bogie remaining produce
Product generate the phenomenon that interference, and therefore, oneself can not fully meet the design requirement of bogie to traditional drawing pull bar structure, this is to traction
The structure of pull rod is put forward new requirements, so it is necessary that we, which design a kind of rail vehicle truck with drawing pull bar,
's.
Summary of the invention
The purpose of the present invention is to provide a kind of rail vehicle truck drawing pull bar,.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of rail vehicle truck drawing pull bar, including drawing pull bar body, mounting hole and rubber nodal point, the traction
A mounting hole is offered at three tip positions of drag link body, and rubber nodal point, the rubber section are socketed in the mounting hole
Point includes mandrel, rubber ring and housing, rubber ring is socketed on the outside of the mandrel, and be socketed with housing on the outside of the rubber ring,
Fitting corresponding with inner wall of the hole installing on the outside of the housing.
As a further solution of the present invention: the drawing pull bar body is in anisotropic shape, and drawing pull bar body two sides pair
Title offers each groove, the drawing pull bar body be located in groove open up there are three long lumbar hole.
As a further solution of the present invention: the rubber nodal point and mounting hole are interference fitted, and the drawing pull bar body is logical
Rubber nodal point is crossed to be connected with bogie and car body.
As a further solution of the present invention: the rubber nodal point distribution triangular in shape, the mandrel, rubber ring and housing
Between by bonding by Vulcanization, sulfide site is spherical structure among the mandrel and housing.
Beneficial effects of the present invention: rubber nodal point distribution triangular in shape, it can so that the connection of bogie and car body is more stable
It leans on, in addition to transmitting tractive force and brake force, also can preferably bear the various impact forces between car body and bogie, mandrel, rubber
By bonding by Vulcanization between ring and housing, mandrel and housing centre sulfide site are spherical structure, are meeting longitudinal rigidity
Meanwhile it also having been increase accordingly the torsion stiffness of rubber nodal point, it ensure that the flexibility of vehicle structure, improve the product of vehicle operation
Matter can satisfy special entrucking bulk requirement using this kind of drawing pull bar, and be unique selection under certain bulks.

Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described reality
Applying example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
Logical technical staff all other embodiment obtained without creative efforts belongs to what the present invention protected
Range.
As shown in Figure 1-3, a kind of rail vehicle truck drawing pull bar, including drawing pull bar body 1, mounting hole 2 and rubber
Glue node 3 offers a mounting hole 2 at 1 three tip positions of drawing pull bar body, is socketed with rubber nodal point in mounting hole 2
3, rubber nodal point 3 includes mandrel 31, rubber ring 32 and housing 33, is socketed with rubber ring 32 on the outside of mandrel 31, and outside rubber ring 32
Side is socketed with housing 33, the fitting corresponding with 2 inner wall of mounting hole of 33 outside of housing；
Wherein, drawing pull bar body 1 is in anisotropic shape, and 1 two sides of drawing pull bar body symmetrically offer each groove 4, traction
Drag link body 1, which is located in groove 4, to be opened up there are three long lumbar hole 5, and weight is effectively mitigated；
Wherein, rubber nodal point 3 and mounting hole 2 are interference fitted, and drawing pull bar body 1 passes through rubber nodal point 3 and bogie and vehicle
Body is connected；
Wherein, the distribution triangular in shape of rubber nodal point 3, so that the connection of bogie and car body is more stable and reliable, in addition to transmitting
