Abstract
The present invention discloses a center plate used in a vehicle for a railway lorry which comprises a upper center plate [1] and a bottom center plate [5]. A downward bulged circular arc face is arranged at the bottom of the upper center plate [1] along the vehicle width direction. A sunken circular arc face which is matched with the circular arc face of the upper center plate is arranged on the bottom center plate [5]. The curve radius of the circular arc face of the body center plate [1] is smaller than the curve radius of the circular arc face of the bottom center plate [5]. The present invention has the advantages that the friction resistance between the upper center plate and the bottom center plate is small when the vehicle swings which facilities to the swing of the vehicle, partly overcomes the snake-like instability when the vehicle runs and increases the speed when the train passes through a curve or a rail switch.
Description
Technical field
The present invention relates to be used for the spider of goods train vehicle.
Background technology
Spider is the parts that connect railway carriage and bogie truck, is made up of body center plate and truck center plate, and body center plate is fixed on the railway carriage bottom, is fixed on the bolster center of bogie truck down to dish, horizontal plate surface bearing that last truck center plate green phase mutual connection touches and transmission car body vertical load.The lorry of present domestic utilization, no matter be open-top car, flatcar, tank car, box car, or most special vehicle, what all adopt is the single stage suspension system, relatively simple for structure, easy access, and manufacturing cost is lower.When low cruise, be fully feasible.But stability, stationarity, the curving performance three contradiction of speed-raising back vehicle are more outstanding, and this mainly is because when speed was low, elastic force was occupied an leading position; Higher when running velocity, when surpassing 100km/h, force of inertia is occupied an leading position; Single stage suspension just can't alleviate or eliminate at all, during the lorry high-speed cruising, need slow down in the time of just can occurring the unstability of crawling, particularly train by curve or road fork in orbit and go slowly, if segment of curve is too high by speed, will cause centrifugal inertia force excessive and influence safe in operation.Especially lorry is under heavily loaded situation, dead-weight capacity all concentrates on the spider, the trend that makes the bolster center have downward flexural deformation, side frames bottom to expand outwardly, be subjected to during the vehicle orbiting under the effect of various transverse forces, make the single wheel off-load of vehicle easily and cause derailing, if various transverse forces are under the least favorable compound action, when the vertical application force between vehicle single wheel and the rail reduced to zero, vehicle had the danger of toppling.
Summary of the invention
The purpose of this invention is to provide a kind of spider that is used for goods train vehicle, can improve the speed of train by curve or road fork.
The present invention is achieved in that it comprises body center plate and truck center plate, the body center plate bottom is along the arc surface of the oriented lower convexity of Width of vehicle, the recessed arc surface that matches with the body center plate arc surface is arranged on the truck center plate, and body center plate arc surface radius of curve is less than the arc surface radius of curve of truck center plate.
When vehicle passes through curve, because inner track is lower than outer side track, body gravity is swung to the inside, and body center plate adopts arc surface to contact with truck center plate, go up the frictional resistance between the truck center plate in the time of can reducing the car body side-sway, make car body be flapped toward the inboard fast, offset train part centrifugal acceleration, thereby can improve the speed of train by curve or road fork.Last truck center plate contact site is designed to sphere, can make car body to any angle pendulum that inclines, and can improve cushioning performance.
The centrifugal mental power function of being used to when utilizing vehicle to cross curve makes the passive pendulum that inclines of car body, and the pivot angle degree that inclines to be to be no more than 3 ° for well, surpasses this radian and can cause the excessive and unstability of centre-of gravity shift.Therefore, last truck center plate arc surface radius of curve is unsuitable too small, and wherein, the arc surface radius of curve of body center plate is preferably 100～130mm, and the arc surface radius of curve of truck center plate is than the big 15～18mm of body center plate arc surface radius of curve.
By arc surface contact, suffer restraints in the horizontal direction and can not relatively rotate between the last truck center plate of above-mentioned spider, can only on the vehicle that uses radial steering, use.In order to use on common bogie truck, sphere is arranged in the body center plate bottom, and described body center plate bottom is the part of sphere along the arc surface of the oriented lower convexity of Width of vehicle; The recessed arc surface that truck center plate matches with the body center plate sphere is an elliptical area, and its major axis is located at the Width of vehicle, and minor axis radius is consistent with the radius of curve of body center plate bottom sphere.The spherical curve radius of body center plate is preferably 100～130mm, and major axis radius is than the big 15～18mm of minor axis radius.
Advantage of the present invention is: go up truck center plate with cambered surface or sphere contact, the frictional resistance of going up between the truck center plate during vehicle swing is little, be convenient to vehicle body swing, can partly overcome the snakelike unstability in the vehicle operating process, car body can be easily during by curve inwardly the inclination pendulum improve the speed of train to offset the part centrifugal acceleration by curve or road fork.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is along A-A line section-drawing among Fig. 1.
Among the figure, 1, body center plate, 2, car body, 3, side bearing, 4, bolster, 5, truck center plate, 6, sphere, 7, elliptical area.
The specific embodiment
Referring to Fig. 1, Fig. 2, body center plate 1 bottom design becomes the sphere 6 to lower convexity, and there is the recessed elliptical area 7 that matches with body center plate sphere 6 truck center plate 5 tops.The section profile of elliptical area 7 shown in Figure 1 is the profile of long axis direction, and the section profile of elliptical area 7 shown in Figure 2 is respectively the profile of short-axis direction, and the minor axis radius of elliptical area 7 is consistent with the radius of curve of body center plate bottom sphere 6.Body center plate 1 sphere 6 radius of curve are unsuitable too small, otherwise can cause carrying too to concentrate and be unfavorable for the normal use of vehicle, cross conference and lose due effect, and the spherical curve radius of body center plate is more suitable between 100～130mm, preferably 115mm.The major axis radius of elliptical area 7 is than the big 15～18mm of minor axis radius, preferably 15mm.Body center plate 1 is fixed on the car body below, because oriented recessed elliptical area 7 makes truck center plate increase than present normally used truck center plate thickness in the middle of the truck center plate 5, can corresponding mounting groove be set on bolster 4 and install.Car body 2 both sides link to each other with bolster 4 by side bearing 3 among Fig. 1, the supporting body of this side bearing 3 also be arranged to and body center plate bottom the consistent sphere of sphere, so more help the car body pendulum that inclines.
At radial steering, because it carries and turns to function, last truck center plate does not need to rotate at horizontal surface, can be arranged to bottom the body center plate along the Width of the vehicle arc surface to lower convexity, and the radius of this arc surface is identical with the radius of above-mentioned sphere 6.Only need on the truck center plate that the recessed arc surface that matches with this arc surface is set and get final product, the size of the arc surface that this is recessed is identical with above-mentioned elliptical area 7 major axis dimension.
