Description
Technical field
The utility model belongs to axle box and is placed in wheel to the rail vehicle truck wheel of inside to device field, and in particular to
A kind of built-in wheel for the built-in bogie of axle box is to composition.
Background technology
As shown in Figure 1, conventional rails car is generally respectively arranged in corresponding wheel composition 6 using two conventional axle boxes 8
Axle 6-2 axial end portions axle box external wheel to structure, such axle box external wheel is to forming typically each directly by embedding
The vertical circular cone metal-rubber spring location structure for entering conventional axle box 8 is linked with framework, outside the structure of conventional axle box 8
Axle 6-2 outer ends are exposed to, lead to that its spacing span is larger, and structure is not compact enough, and in order to protect such protrude from the outside of rail
8 structure of external routine axle box from accidental impact, external axle box need to add protective cover, but this mode not only gives conventional shaft
The maintenance of case 8 is made troubles, more so that lateral span is larger between such old external axle box spacing and wheel 6-1,
Occupied space is more, and the minimum curve for being unfavorable for bogie passes through the raising of performance.
On the other hand, modern subway line proposes the min. turning radius of its bogie increasingly harsh new demand.
The built-in metro bogie 7 of a kind of novel axle box as shown in Figure 9 and Figure 10 can be while structural strength be ensured substantially
Reduce bogie fixed wheelbase, so as to reduce the radius of gyration of bogie, improve its small curve negotiation ability.The novel steering frame
The curb girder end of framework 7 is equipped with special letter C shape axle box mounting base 7-1, is equipped in two open ends of its letter C shape
The axle-box locating bar mounting hole 7-1-1 coaxially penetrated through.According to the designing scheme of the New Metro Bogie, axle box mounting base 7-
1 needs directly with corresponding novel axle box structure to match, so that novel axle box can be fully mounted to axle box mounting base
The inside of 7-1, so as to form a kind of built-in bogie layout structure of completely new axle box.
But even if existing external structure of axle box removes its protective cover, still can not directly with letter C shape axle box mounting base
The direct Matching installations of 7-1.For this purpose, it is badly in need of research and development and designs a load reasonable design, exquisiteness simple in structure, is easily installed dimension
Repair, and can match and suitable for C-shaped axle box mounting base novel built-in type wheel to composition.
Utility model content
In order to solve the axle box external wheel of the existing axle ends that corresponding wheel is respectively arranged in there are two axle box to knot
Structure, axle box usually expose to axle outer end, lead to that its spacing span is larger, and structure is not compact enough, are unfavorable for turning for bogie
The raising of the mobility such as curved and speed-raising, and that newly develops is placed in rail of the wheel to inside with letter C shape axle box mounting base and axle box
The road bogie of car, then lack be corresponding to it matched built-in wheel to composition, therefore can not by reduce axle box spacing and
Wheel transverse direction span and improve the technical issues of minimum curve of bogie passes through performance, the utility model, which provides, a kind of is used for axis
The built-in wheel of the built-in bogie of case is to composition.
The utility model technical solution adopted for solving the technical problem is as follows：
For the built-in bogie of axle box built-in wheel to composition, include wheel composition and two sets of built-in axles dresses
It puts, every suit built-in axle device includes trapezoidal axle box, two block ridged rubber spring pieces form, positions drawbar, two
Rubber spring piece positioning checkpoint and semi-circular axle box anticollision gasket；The stage casing of the positioning drawbar and the bottom surface of trapezoidal axle box are lived
Dynamic connection；Two block ridged rubber spring pieces composition is fixed on respectively by the way that a corresponding rubber spring piece positioning checkpoint is parallel
On one stringcourse of trapezoidal axle box；The lower end of rubber spring piece positioning checkpoint is connected with the upper bottom end of trapezoidal axle box, rubber bullet
Stringcourse of the top that reed positioning checkpoint is made up of corresponding block ridged rubber spring piece its claw along trapezoidal axle box
Lateral wall is to oblique outer side compression；The bottom of ridge-shaped rubber spring piece composition is seated on trapezoid shaft bottom seat.
The cross section of the trapezoidal axle box is isosceles trapezoid, and the center of trapezoidal axle box is equipped with the axle pilot hole of perforation；Make
The top of lateral wall for trapezoidal two stringcourses of axle box is equipped with clamp installation screw, and the bottom of lateral wall is equipped with extension pedestal；
Vertical anticollision backstop is equipped in the middle part of the upper bottom of trapezoidal axle box；Axle pilot hole outer diameter positioned at trapezoidal axle box inner side end is equipped with
Semiorbicular anticollision gasket mounting base is equipped with round anticollision positioned at the axle pilot hole outer diameter of trapezoidal axle box end face outside and stops
Gear；The middle part of rubber spring piece positioning checkpoint is connected by bolt and clamp installation screw.
The stringcourse of the trapezoidal axle box and the angle of bottom are 79 degree；Same wheel is between two trapezoidal axle boxes on composition
Less than being 1165 millimeters.
The cross section of the lateral wall is the V-shaped that symmetrical, middle part is connected, and the angle of dehiscing of V-shaped is 120
Degree.
Each ridge-shaped rubber spring piece of ridge-shaped rubber spring piece composition be cross section for it is symmetrical,
The V-shaped that middle part is connected, length, width and angle of dehiscing match with the end face outside of lateral wall；Multiple ridge-shaped rubbers
Glue spring leaf, which is laminated to be connected, forms a ridge-shaped rubber spring piece composition；Positioned at innermost layer ridge-shaped rubber spring piece with it is right
The lateral wall matching answered fastens.
The beneficial effects of the utility model are：The built-in wheel built-in axle device of composition is used cross section for etc.
The trapezoidal trapezoidal axle box of waist causes the novel trapezoidal axle box of the utility model only to be undertaken from the dispersion of two bevel direction and carrys out rotation
To the gravitational load of frame, the first half lateral wall of trapezoidal axle box locally carries the gravitational load of axle box mounting base, trapezoidal axle box
Lower half then with axle wide arc gap buffer coordinate, the structure design is compared to traditional circular cone metal-rubber bullet of vertical load
Spring can obtain very big longitudinal rigidity, so as to obtain the high speed of higher vehicle in the case where ensureing low vertical stiffness
Stability.Since the built-in axle structure has fully phased out shaft end installation equipment, it can effectively prevent traditional subway and turn
To the various equipment in frame shaft end in impact occurs for nearly track object or track itself and draws all kinds of failures or accident.
The utility model is by setting rational structural parameters by placement position of the trapezoidal axle box on axle by traditional
Shaft end is changed to the inner side end for being close to wheel, and matches its C-shaped inner cavity with the axle box mounting base with smaller span and be connected,
The design can effectively prevent the axial float that ridge-shaped rubber spring piece forms, and the supplementary protection for replacing axle box old simultaneously
Outer cover facilitates the current check of bearing, so that using the utility model for the built-in of the built-in bogie of axle box
Wheel is significantly reduced at least 36 meters by radius to the minimum curve of the train bogie of composition by old at least 100 meters, into
And greatly improve turning mobility and the flexibility of this novel steering frame.
In addition the built-in wheel for being used for the built-in bogie of axle box also has composition simple and practical in structure, at low cost
It is honest and clean, the advantages that convenient for popularizing.
