Abstract
There is the journal box spring of lifting function, the overcoat comprising mandrel and be connected with mandrel sulfuration, mandrel stretches out from the two ends of overcoat, it is characterized in that described overcoat is the bucket shape of base seal, the lower end of mandrel passes from the bottom of overcoat, the lower end of described mandrel is fixedly connected with limit stops, described limit stops immediately below overcoat and and between overcoat, there is gap, the bottom of limit stops and overcoat leans the axial deformation of the journal box spring described in limiting.Journal box spring of the present utility model can realize the function of bogie truck integral lifting, simplifies the space structure between bogie truck and axle box, avoids wheel to be that vertical damper position is interfered mutually to lift and one.
Description
Technical field
The utility model relates to the journal box spring for connecting between bogie truck and axle box, particularly has the journal box spring of lifting function.
Background technology
Current railway passenger car bogie is all provided with special wheel to lift, to realize the function of bogie truck integral lifting, wheel is generally divided into two parts to lifting, part structure welding is in lateral beam of bogie termination or together with being cast in spring strut, another part is arranged on pivoted arm or axle box, parts are many, space structure is complicated, and manufacturability is not generally fine, also need herein to arrange one is vertical damper simultaneously, therefore space is nervous, often occurs that wheel is the situation that vertical damper position is interfered mutually to lifting and one.
If certain link between bogie truck and axle box can be utilized to realize wheel to lifting, the function of bogie truck integral lifting can be realized, wheel is avoided again to be vertical damper location conflicts to lift and one, just do not need to arrange wheel more extraly to lift, simplify structure to the space structure between frame and axle box yet.
Utility model content
The utility model to cause between bogie truck and axle box space structure complicated for the wheel on bogie truck to lift and and one be the technical matters that vertical damper position is interfered mutually, there is provided and there is the journal box spring of wheel to lifting function, the function of bogie truck integral lifting can be realized, simplify the space structure between bogie truck and axle box, avoid wheel to be that vertical damper position is interfered mutually to lift and one.
For achieving the above object, the technical solution adopted in the utility model is: the journal box spring with lifting function, the overcoat comprising mandrel and be connected with mandrel sulfuration, mandrel stretches out from the two ends of overcoat, it is characterized in that described overcoat is the bucket shape of base seal, the lower end of mandrel passes from the bottom of overcoat, the lower end of described mandrel is fixedly connected with limit stops, described limit stops immediately below overcoat and and between overcoat, there is gap, the bottom of limit stops and overcoat leans the axial deformation of the journal box spring described in limiting.
Further, described jacket bottom center has through hole, and described mandrel lower end passes from through hole, and the diameter of described through hole is a bit larger tham the diameter of described mandrel lower end.
Further, described limit stops and the axially spaced-apart of jacket bottom are 2mm ~ 6mm.
Further, described limit stops is arranged on the bottom of mandrel, and described mandrel lower end is in falling " T " font.
Further, described overcoat is made up of stack shell and base plate, and described base plate and stack shell interference fit are arranged on the bottom of stack shell, and described through hole is opened in the center of described base plate.
The journal box spring of tool lifting function of the present utility model, the journal box spring be connected between bogie truck and axle box to be optimized and improvement makes journal box spring have lifting function, overcoat in journal box spring is modified into the bucket shape of base seal, and in the lower end of mandrel, limit stops is set, limiting block immediately below overcoat and and between overcoat, there is gap, when mandrel and overcoat oppositely move, between limit stops and overcoat, gap reduces gradually, the bottom of limit stops and overcoat leans and limits the axial deformation of journal box spring, avoid degree of drawing tensile damage journal box spring.When mandrel or outer shaft apply lifting force, limit stops and overcoat oppositely movement lean, and utilize the journal box spring of axially not redeformation to transmit lifting force, realize the function of bogie truck integral lifting.Utilize journal box spring to realize wheel to lifting, both avoided, and on bogie truck, special wheel had been set to lift, and simplified the space structure between bogie truck and axle box, avoid again wheel to be that vertical damper position is interfered mutually to lift and one.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of overcoat.
Detailed description of the invention
To be further described the utility model by drawings and Examples below.
As shown in Figure 1 to Figure 2, there is the journal box spring of lifting function, the overcoat 12 comprising mandrel 11 and be connected with mandrel 11 sulfuration, mandrel 11 stretches out from the two ends of overcoat 12, described overcoat 12 is the bucket shape of base seal, described overcoat 12 bottom centre has through hole 12.1, and described mandrel 11 lower end passes from through hole 12.1, and the diameter of described through hole 12.1 is a bit larger tham the diameter of described mandrel 11 lower end.The bottom that limit stops 11.1 is fixed on mandrel 11 makes described mandrel 11 lower end in falling " T " font, described limit stops 11.1 is positioned at immediately below overcoat 12, described limit stops 11.1 is 2mm ~ 6mm with the axially spaced-apart bottom overcoat 12, and limit stops 11.1 and the bottom of overcoat 12 lean the axial deformation of the journal box spring 1 described in limiting.
Described overcoat 12 is made up of stack shell 12.2 and base plate 12.3, and described base plate 12.3 and stack shell 12.2 interference fit are arranged on the bottom of stack shell 12.2, and described through hole 12.1 is opened in the center of described base plate 12.3.
The above-mentioned journal box spring with lifting function, is optimized the journal box spring be connected between bogie truck and axle box and improves, and utilizes journal box spring to realize wheel to lifting.When journal box spring applies lifting force, the bottom of overcoat 12 and backstop 11.1 oppositely movement, when overcoat 12 and the axially spaced-apart of backstop 11.1 are reduced to zero, overcoat 12 is with backstop 11.1 against axial deformation limit journal box spring, and journal box spring transmission lifting force, by bogie truck integral lifting.Avoid, on bogie truck, special wheel is set to lift, simplify the space structure between bogie truck and axle box, avoid again wheel to be that vertical damper position is interfered mutually to lift and one.Moreover limit stops 11.1 leans with the bottom of overcoat 12 and limit the axial deformation of journal box spring, it also avoid excessive tensile and damage journal box spring.
Below by reference to the accompanying drawings complete description is carried out to the technical scheme of the utility model embodiment; it should be noted that described embodiment is only the utility model part embodiment; make based on the embodiment in the utility model; the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
