Description
Technical field
The invention belongs to the sleeper beam device field for rail vehicle truck, and in particular to one kind is delayed with central cross
Rush the new sleeper beam device of device.
Background technology
The framework of existing bogies for railway vehicles is typically axle box external bogie, as shown in Figure 1 to Figure 2, common
Axle box external bogie be a kind of welded frame for the approximate H fonts being collectively forming by two crossbeams 1 and two curb girders 3,
The basic composition of its framework includes two longerons, 2, two crossbeams 1 and is fixed on the curb girder 3 at the both ends of crossbeam 1, and it is welded jointly
The structure for the capital H type being connected into, each crossbeam 1 include one group of drawing pull bar seat 1-4, and two seamless steel pipe 1-1 are each other
Parallel, the spacing both it is bridged and fixed by two parallel longerons 2 respectively, and two crossbeams 1 and two longerons 2 close jointly
Enclose to form a rectangular window region.The rectangular window region is used to accommodate and install similar to Chinese patent CN 104442882
The vertically arranged drawing pull bar of disclosed zigzag and traction seat, its parallel to each other and vertical centre axis Z using bogie as
Rotation centerline carries out rotational symmetry distribution, two drawing pull bars of two groups of zigzags arrangement respectively with corresponding drawing pull bar seat
1-4 is hinged.In addition, the both ends of longeron 2 are connected with two crossbeams 1 respectively, the upper end stage casing of longeron 2 is provided with framework transverse direction backstop 2-
1, it is provided with a transverse damper seat 2-2 in the one end of longeron 2.Two crossbeams 1 are using the vertical rotary shaft Z of framework as in rotational symmetry
The heart, each other by 180 ° of angle of circumference rotational symmetry, two transverse damper seat 2-2 are respectively used to laterally subtract corresponding to installation one
Shake device.The air spring mounting hole 3-1 that the middle part of curb girder 3 is set is directly used in coaxially to be connected with air spring.
However, foregoing common drawing pull bar is located inside the rectangular window at bogie frame center, and two transverse directions subtract
Shake device is arranged in layout type on rectangular window diagonal, is generally only applicable to larger dynamic of frame size and weight
Car group axle box external bogie frame, because the structural strength of large scale framework is big, makes it possess more broad attaching part
Part arrangement space loads the larger suspension of moment of torsion or boom structure.
On the other hand, a kind of new axle box built-in ground iron casting bogie 4 as shown in Figure 3 can ensure structure
Significantly reduce bogie fixed wheelbase while intensity, so as to reduce the radius of gyration of bogie, improve its small curve negotiating energy
Power.The built-in axle of the novel steering framework frame 4 need to be fully mounted to axle box mounting seat 4-1 inside, so as to form one kind
The built-in bogie layout structure of brand-new axle box.But due between the curb girder of the novel axle box built-in ground iron casting bogie 4
It is in light weight away from small, cause its physical dimension and structural strength that significant changes occur：The new framework by casting technique one into
Type, it only remains columnar traction seat in the geometric center of framework, but eliminates by two crossbeams 1 and two institutes of longeron 2
The original structures such as the middle part rectangular window to be formed, transverse damper seat and framework transverse direction backstop are surrounded jointly.
For this reason, it may be necessary to redesign a new compact bolster structure, drawing pull bar, horizontal shock-absorbing dress are considered
Put and the layout of air spring and assembling, to adapt to the application demand of axle box built-in ground iron casting bogie.
The content of the invention
It is existing by the integrally formed novel axle box built-in ground iron casting bogie of casting technique in order to solve, during it is cancelled
The original structures such as portion's rectangular window, transverse damper seat and framework transverse direction backstop, it is therefore desirable to consider drawing pull bar, horizontal stroke
To the layout and assembling of damping device and air spring, a new compact bolster structure is redesigned, to adapt to
The technical problem of the application demand of axle box built-in ground iron casting bogie, the present invention provide one kind and carry central cross buffer
New sleeper beam device.
The technical solution adopted for solving the technical problem of the present invention is as follows：
New sleeper beam device with central cross buffer include sleeper beam matrix, horizontal buffer, sleeper beam core cylinder, two
Drawing pull bar free bearing, two vertical damper pedestal, two anti-side rolling torsion rod seats, two framework connection pedestals, two air bullets
Spring mounting seat and two flap seats, sleeper beam matrix are rectangular configuration, and two are played the both ends that flap seats are fixed on sleeper beam matrix；Sleeper beam core
The vertical center for being fixed on sleeper beam matrix lower surface of cylinder, horizontal buffer are fixed on the center of upper surface under sleeper beam matrix；Two
Drawing pull bar free bearing is symmetrically fixed on the both ends of sleeper beam matrix same long side, and each vertical damper pedestal is upward opening
Groove structure, its recess sidewall drawing pull bar free bearing madial wall corresponding with one in the outer part is connected；
Described two framework connection pedestals are symmetrically arranged in the bottom of sleeper beam matrix, framework with the central plane of sleeper beam matrix
The distance values for connecting pedestal to sleeper beam core cylinder play flap seat to the half of the distance values of sleeper beam core cylinder, framework connection pedestal for its homonymy
Length be two times of width of sleeper beam matrix；Two air spring mounting seats are symmetrically arranged in the central plane of sleeper beam matrix
The upper end of sleeper beam matrix；Air spring mounting seat be located at its close on framework connection pedestal and vertical damper pedestal both it
Between；Each anti-side rolling torsion rod seat is fixed on a corresponding air spring mounting seat radial outer edge, described two anti-side rollings
Torsion bar seat is respectively positioned on the side where an other long side for sleeper beam matrix.
The sleeper beam matrix, sleeper beam core cylinder, two drawing pull bar free bearings, two vertical damper pedestal, two anti-side rollings
Torsion bar seat, two framework connection pedestals, two air spring mounting seats and two play flap seat by casting integrated shaping, and it is rested the head on
The gross weight of beam matrix is 460 kilograms, average wall thickness is 16 millimeters.
The spacing of described two framework connection vertical central planes of pedestal is 1095 millimeters；Two drawing pull bar free bearings are vertical
The spacing of central plane is 2370 millimeters；The spacing of the vertical central plane of two vertical damper pedestal is 2010 millimeters；Two
The spacing of the vertical central plane of anti-side rolling torsion rod seat is 1573 millimeters；The spacing of two frameworks connection vertical central planes of pedestal is
1116 millimeters；Two air spring mounting seat 5-8 axis spacing is 1556 millimeters；Between the two vertical central planes of flap seat
Away from for 2340 millimeters.
The horizontal buffer includes pedestal square box, two groups of width adjustment pieces, two rubber shock-absorbing cushion blocks and two set of solder
Backing plate, the side wall of each described rubber shock-absorbing cushion block and a corresponding width adjustment piece sequentially with pedestal square box are consolidated
Even, two rubber shock-absorbing cushion blocks are mutually symmetrical；Two other side wall end face of pedestal square box solder pads corresponding with one respectively
Plate weld is connected；The upper and lower edge of solder backing plate is respectively formed filler gap with the upper end cover of pedestal square box and corresponding side wall respectively；
The center weld of the lower end of pedestal square box and sleeper beam matrix upper surface is connected.
