Abstract
An opposite angle stayed connecting mechanism for a railway vehicle wheel set is characterized in that pull rod seats (3) are arranged on axle boxes (2) or adapters on different sides of front and rear wheel sets (11 and 12) of a bogie; and two ends of a diagonal pull rod (4) are hinged on the pull rod seats (3) through a hinge component. The mechanism can decouple the shearing rigidity and the shaking rigidity between the two wheel sets of the same bogie; on the premise of no influence on the shaking rigidity, the utility model can improve the shearing rigidity remarkably, thereby improving the running stationarity of vehicles on the basis of no influence on the curve passing performance of the vehicles.
Description
Technical field
The utility model relates to a kind of mechanism that is used for configuration in railroad truck.
Background technology
The wheel of existing railway vehicle is to all being to realize location with respect to framework by the resilient suspension parts.Main line load carrying vehicle bogie truck generally all is two axle truck (i.e. corresponding two wheels of framework to), for lorry, the framework of bogie truck directly is supported on and carries on the saddle, and adapter is supported on the bearing of the right wheel shaft of wheel, the contact friction of framework and adapter by bogie truck, come limited wheel right laterally, vertically move and move along shaking the head of vertical axis rotation.For passenger vehicle and locomotive, the framework of bogie truck is supported on wheel to axle box by the journal box spring suspension gear, and realize bogie truck with take turns between horizontal and vertical location.Take turns when one of them and (to be called the motion of shaking the head again) taking turns relative to another to side travel or when vertical axis is rotated, because the constraint of truck frame, wheel to thereby have mainly shear rigidity that produces by side travel and the rigidity of shaking the head that mainly produces by the motion of shaking the head, the shear rigidity and the rigidity of shaking the head is the linear running stability and the curving performance of appreciable impact railway vehicle respectively.They are finally by the suspension parameter decision of wheel to elasticity location, and promptly the rigidity of the suspension gear of being made up of the contact friction of adapter and framework or the spring between framework and axle box and pull bar etc. is definite.Because shear rigidity is to guarantee by identical parts with the rigidity of shaking the head, so has very strong relevance between the two, make the shear rigidity and the rigidity of shaking the head change in the same way, promptly when shear rigidity increased, the rigidity of shaking the head also can correspondingly increase.But for the curving performance that guarantees vehicle is good, require wheel little usually to the rigidity of shaking the head, but because it is related with shear rigidity, and then shear rigidity is also corresponding reduces, and reducing of shear rigidity but is unfavorable for the straight line smooth running of vehicle.Therefore, need a kind ofly to make the right shear rigidity of wheel and the device of the decoupling zero between the rigidity of shaking the head, make it can satisfy the different requirements of shear rigidity and the rigidity of shaking the head.
The utility model content
The purpose of this utility model just provides a kind of railway vehicle wheel diagonal member is drawn bindiny mechanism, this mechanism can make two wheels of same bogie truck to the shear rigidity and the decoupling zero between rigidity of shaking the head, under the situation that does not influence the rigidity of shaking the head, significantly improve shear rigidity, thereby on the basis of the curving performance that does not influence vehicle, improve the stationarity of vehicle operating.
The utility model is realized its goal of the invention, the technical scheme that is adopted is: a kind of railway vehicle wheel draws bindiny mechanism to diagonal member, its constructional feature is: the front and rear wheel of bogie truck on the axle box of not homonymy or adapter on draw-bar seat is set, the two ends of digonal link are articulated on the draw-bar seat by articulated section.
Working process of the present utility model and principle are: with mechanism of the present utility model set up the wheel of existing vehicle on.Since digonal link directly with front and back wheel on the same bogie truck to oblique hinged, make when a wheel to another is taken turns when side travel takes place relatively, owing to the constraint of digonal link, shear rigidity traversing relatively between them will significantly increase.And when shaking the head motion about taking place between the two because digonal link is on two wheel tracks at the vertical diagonal angle that is hinged on same bogie truck, take turns right shaking the head move unfettered, thereby do not influence wheel to the rigidity of shaking the head.
Compared with prior art, the beneficial effects of the utility model are:
One, on existing bogie truck basis, improve wheel to lateral shear rigidity.Because it does not change the rigidity of shaking the head, can not change the curving performance of the bogie of car, therefore the utility model can design and manufacture the bogie truck of the rigidity of shaking the head up to specification earlier, make it satisfy the curving performance of vehicle, design and manufacture the mechanism of the present utility model of certain stiffness more on request, make it take turns right shear rigidity and also meet the demands, thereby make the curving performance of vehicle and straight line stationarity all reach optimum regime.
Two, the decoupling zero of rigidity and shear rigidity because mechanism described in the utility model has realized shaking the head, therefore the shear rigidity in can realizing in a big way cooperates with the rigidity of shaking the head, thereby can realize a series of location suspension parameter optimal design of shipping bogie truck and passenger traffic bogie truck in the larger context, help the development of high speed, heavy haul railway.
Three, the utility model only needs at existing two-wheeled oblique connection one digonal link to be got final product, and need not existing bogie truck is carried out other transformation, and it is convenient to implement.
The two ends pivotally attached articulated section of above-mentioned draw-bar seat and digonal link is an oscillating bearing.
Above-mentioned draw-bar seat and digonal link two ends pivotally attached articulated section are rubber arthrosis.
Adopt existing ripe oscillating bearing and rubber arthrosis, can make the hinge point of digonal link easy for installation, rotate flexibly, reliable, the recruitment that can conveniently select for use oscillating bearing with desired parameters and rubber arthrosis to obtain required shear rigidity again.
Above-mentioned digonal link be shaped as the shape that can avoid miscellaneous part in the bogie truck.Like this, the utility model can not influence the normal operation of existing bogie truck, also makes enforcement of the present utility model easier for installation simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Fig. 1 is the plan structure scheme drawing of the utility model embodiment one.
The specific embodiment
Embodiment one
Fig. 1 illustrates, a kind of specific embodiment of the present utility model is: a kind of railway vehicle wheel draws bindiny mechanism to diagonal member, on the axle box 2 of the front and rear wheel of the bogie truck not homonymy on to 11,12 draw-bar seat 3 is set, the two ends of digonal link 4 are articulated on the draw-bar seat 3 by articulated section.Draw-bar seat 3 is an oscillating bearing with digonal link 4 two ends pivotally attached articulated sections.Digonal link 4 be shaped as the shape that can avoid miscellaneous part in the bogie truck, as the zigzag among Fig. 1.This routine structure is suitable for taking turns passenger vehicle or the locomotive to last installation axle box.
Embodiment two
This example and embodiment one are basic identical, different only be: on the adapter of the front and rear wheel of the bogie truck not homonymy on to 11,12, draw-bar seat 3 is set.Draw-bar seat 3 is a rubber arthrosis with digonal link 4 two ends pivotally attached articulated sections.This routine structure is suitable for taking turns the lorry to last installation adapter.
