Description
Technical field
The utility model relates to journal box of truck of rail wagon, refers to particularly a kind of journal box of truck of rail wagon resilient suspension shock attenuation unit.
Background technology
Heavy haul transport is one of main direction of railway freight development, and the load of railway truck is heavier, and is also larger to the heavy requirement of axle to steering framing wheel.Studies show that, the following quality size of the wheel track dynamic deformation from motion of railway truck and bogie truck bearing spring has direct relation, between the wheel set bearing of bogie truck and side frame guide, the unsprung weight that axle box shock-absorbing device (also claiming primary spring) can effectively reduce bogie truck is set, and then reduces the wheel track dynamic deformation from motion.
At present, the railway scientific research personnel has designed various forms of axle box elastic vibration clampers, wherein adopting the conical rubber pile vibration damping is exactly a kind of axle box elastic vibration clamper commonly used, although this device is comparatively obvious to the effect of bogie truck Vertical Vibration Reduction, for the inhibition of horizontal, longitudinal vibration Shortcomings comparatively speaking.The axle box elastic cushion shock attenuation unit that adopts three layers of lining, two-layer rubber is also arranged, but its mainly for large laterally, the demand of longitudinal rigidity and less vertical stiffness, the strong and complex structure of commonality is unfavorable for the dismounting maintenance.Adopt in addition the compound type axle box suspension gear of vertical cushion, the first longitudinal elasticity pad and the second longitudinal elasticity pad, although it can guarantee vehicle smoothness, relax wheel-rail impact, it is comprised of a plurality of parts, makes relative complex, assembly and disassembly are consuming time more, and maintenance is also inconvenient.
Along with the day by day intensification of railway transportation heavy loading, the axle of rail freight is heavy constantly to be increased, and existing axle box shock-absorbing device can not satisfy the high standard requirement that further alleviates the wheel track dynamic deformation from motion, reduces wheel-rail wear and tear.Therefore, the scientific research personnel improves the primary spring of journal box of truck of rail wagon, design a kind of railway goods train bogie that can make and rationally bear axle box shock-absorbing device vertical, horizontal, longitudinal loading, this to the wheel rail dynamics performance of improving the heavy duty goods train bogie truck, improve railway truck riding quality significant.
Summary of the invention
The purpose of this utility model is will provide a kind of and can effectively reduce dynamic deformation from motion between wheel track, be convenient to vehicle by curve, simultaneously simple in structure, be easy to install and remove, the journal box of truck of rail wagon resilient suspension shock attenuation unit of convenient maintenance.
For achieving the above object, the journal box of truck of rail wagon resilient suspension shock attenuation unit that the utility model is designed, be installed between the wheel set bearing and side frame guide of bogie truck, it comprises the carrying saddle that is fixed on the wheel set bearing top, its special character is: described carrying saddle top is provided with a pair of resilient sleeper-bearing, and described a pair of resilient sleeper-bearing is formed by the whole sulfuration of top steel plate, intermediate rubber layer and bottom steel plate pressing respectively and the downward-sloping Contiuum type herringbone structure that is in cross-sectional plane both sides of intermediate rubber layer; Described a pair of resilient sleeper-bearing also tilts to be arranged symmetrically with, longitudinally to be split type herringbone structure take the axial line of wheel set bearing as benchmark; Top steel plate and the side frame guide of described a pair of resilient sleeper-bearing are located by connecting, and the bottom steel plate of described a pair of resilient sleeper-bearing is located by connecting with the carrying saddle.
The utility model has the advantage of: designed a pair of resilient sleeper-bearing adopts double word distribution form, the intermediate rubber layer of himself is along laterally being the Contiuum type herringbone structure on the one hand, it is arranged symmetrically with take the wheel shaft axial line as benchmark on the carrying saddle on the other hand, longitudinally be split type herringbone structure, so no matter to be that the literal or vertical people of horizontal people is literal all at a certain angle with vertical guide shape, both can give full play to the advantage of rubber layer elasticity of shearing and compression combination, make truck journal box easily obtain larger vertical amount of deflection and suitable vertically, lateral stiffness; Again can be according to the needs of reality delivery, by adjusting the angle between the literal and vertical guide of people, make a pair of resilient sleeper-bearing bear flexibly vertical, the horizontal and vertical load of different proportion; Thereby effectively reduce dynamic deformation from motion between wheel track, significantly alleviate abrasion between wheel track, improve vehicle by the performance of curve.Simultaneously, the resilient sleeper-bearing of herringbone layout is compared with traditional integrated elastic suspension gear by two monomer compositions, and monomer weight is lighter, manufacturing is convenient, assembly and disassembly are still less consuming time and easier operation and maintenance.
As preferred version, the steel plate both sides, top of described resilient sleeper-bearing are provided with the top rib, the corresponding detachable locator card flush fit of top guide groove on described top rib and the side frame guide; The steel plate both sides, bottom of described resilient sleeper-bearing are provided with the bottom rib, described bottom rib and the carrying corresponding detachable locator card flush fit of bottom guide groove on the saddle.Like this, only depend on when mounted the self gravitation of bogie truck just resilient sleeper-bearing can be press-fit into place, the truck side frame of only need slinging during dismounting can be realized the decomposition of this device.
Further, described resilient sleeper-bearing and comprise angle α better between the vertical guide of wheel set bearing axial line=65 ~ 75 °, best angle α=68 ~ 72 °.
Further, the better angle β between the intermediate rubber layer cross-sectional plane both sides of described resilient sleeper-bearing=130 ~ 150 °, best angle β=136 ~ 144 °.
Again further, the better thickness h of the intermediate rubber layer cross-sectional plane of described resilient sleeper-bearing=30 ~ 50mm, best thickness h=35 ~ 45mm.
The setting of above-mentioned parameter, the vertical amount of deflection that railway goods train bogie can be born in transportation and state vertical, that lateral stiffness is adjusted to matched well, thereby the dynamic deformation from motion between reduction vehicle wheel track alleviate the vertical and laterally wearing and tearing between wheel track.
Again further, the upper steel plate top surface of described resilient sleeper-bearing is the integral planar structure, and the steel plate bottom surface, bottom of described resilient sleeper-bearing also is the integral planar structure.Like this, heat conductivity was good when resilient sleeper-bearing was made in sulfuration, and integrated molding intensity is high, stable and reliable product quality, and the resilient suspension cushioning performance is excellent.
