Description
Technical field
The utility model is related to railcar wheel technical field, specifically a kind of spoke of railcar wheel.
Background technology
In the prior art, track traffic wheel is typically by wheel hub, spoke and forms the wheel of wheel rim and running surface of wheeltrack
Rim is constituted.The shell that spoke is made up of the plane being connected, the conical surface or curved shell system.The shape of spoke disc
Have：Straight wheel plate, s types disc, undaform disc, basin type disc.The shape of disc has larger to the structural strength and rigidity of wheel
Influence, its radial rigidity can make wheel have larger elasticity, can improve the stress state and drop of wheel under braking thermic load
Low wheel-rail dynamic interaction.The axial rigidity of disc should try one's best greatly, reduce the axial deformation of wheel, prevent the normal contact position of wheel track
With wheel rim angle, influence vehicle runnability climbs the possibility of rail with increase.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the utility model provides a kind of wait should
The spoke of the railcar wheel of power, high casting material density and quality.
The technical scheme that the utility model is used is：Spoke described in the utility model is the shell of butterfly s basin type disc, is connect
The shell of nearly wheel hub is butterfly s basin types, and the shell close to wheel rim is parabolic curve shape, in the butterfly s basins type and parabolic curve
Shell between shape is the basin bottom shape of asymptote curve.
The utility model can use different the butterfly s basins type, parabolic curve shape, the number of asymptote curve shell that are connected
Amount, butterfly s basins type, parabolic curve shape, the mutual alignment of asymptote curve shell, and shell cross section profile central longitudinal axis incline
Rake angle, different building method realizes the raising of Wheel Fatigue intensity and dynamic strength.
The curvature e of the s basin types of butterfly s basin types described in the utility model is equal to 0.8-1.0, and the butterfly s basins type shell is highly
The 8~12% of the shell depth.
The depth of parabolic curve shape shell described in the utility model is the 23~9% of the shell depth.
Eccentricity e >=1 of the asymptote curve of basin bottom described in the utility model shape, with e increase, hyperbola dehisce by
Gradual change obtains open, and the depth of basin bottom shape is the 69~79% of the shell depth.
Spoke design is the shell of butterfly s basin types in the utility model, and the shell close to wheel hub is butterfly s basin types, with the application
The utility model patent of identified patent applications number 201120423872.0 is compared before people, and former spoke design is thin for butterfly basin type
Shell, the shell close to wheel hub is taper, is compared, the design of the application butterfly s basin shapes, its radial rigidity can make wheel have larger
Elasticity, can improve the stress state of wheel and reduction wheel-rail dynamic interaction under braking thermic load；The design of original application butterfly basin type,
Shell close to wheel hub is designed as taper, and radial rigidity is big, so that elastic smaller, effect of the wheel track for wheel track of wheel
Power strengthens, so as to reduce the service life of spoke.
The beneficial effects of the utility model are：The spoke of the utility model railcar wheel is thin using butterfly s basin type disc
Shell, the shell close to wheel hub is butterfly s basin types, and the shell close to wheel rim is parabolic curve shape, in the butterfly s basins type and parabola
Shell between shaped form is the basin bottom shape of asymptote curve, and its radial rigidity can make wheel have larger elasticity, can improve
Brake the stress state of wheel and reduction wheel-rail dynamic interaction under thermic load.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of the spoke of the utility model railcar wheel.
In figure, 1- railcar wheel 2- wheel hub 3- spoke 4- wheel rim 5- wheel rim 6- runnings surface of wheeltrack.
Embodiment
In order to deepen to understand of the present utility model, further detailed is made to the utility model with reference to the accompanying drawings and examples
Thin explanation.Following examples are only used for clearly illustrating the technical solution of the utility model, and can not be limited with this
Protection domain of the present utility model.
As shown in figure 1, railcar wheel 1 includes wheel hub 2, spoke 3 and the wheel rim 4 for forming wheel rim 5 and running surface of wheeltrack 6.
Spoke 3 of the present utility model is the shell of the butterfly s basin type disc by being connected, including close to the butterfly s basin types of wheel hub,
Close to the shell parabolic curve shape of wheel rim, the shell between butterfly s basins type and parabolic curve shape is the basin of asymptote curve
The shell of the shape of bottom shape system composition.
Shell close to wheel hub 2 is butterfly s basin types, the C sections in such as Fig. 1, and the curvature e of butterfly s basin types is equal to 0.96, and its height is
The 10% of shell depth h.
Shell close to wheel rim 4 is parabolic curve shape, the A sections in such as Fig. 1, and close to the parabolic curve shape of wheel rim 4
Depth h1 is the 19% of shell depth h.
In the basin bottom shape that the C sections of shells between A sections of parabolic curve shape of butterfly s basin types are asymptote curve, in Fig. 1
B sections, eccentricity e >=1 of asymptote curve, with e increase, hyperbola dehisces gradually to become open, the basin of asymptote curve
The depth h2 of bottom shape is the 71% of shell depth h.
The utility model uses the shell of butterfly s basin type disc, including close to the butterfly s basin types of wheel hub, close to the shell of wheel rim
Parabolic curve shape, the shell between butterfly s basins type and parabolic curve shape is the basin bottom shape system composition of asymptote curve
The shell of shape.Cone shell in the prior art close to wheel hub is changed to butterfly s basin types close to wheel hub, butterfly s basins type and taper
Shell compare, its radial rigidity can make wheel have larger elasticity, can improve braking thermic load under wheel stress shape
State and reduction wheel-rail dynamic interaction.
It is noted that embodiment described above is to the illustrative and not limiting of technical solutions of the utility model, affiliated skill
The equivalent substitution of art field those of ordinary skill or other modifications made according to prior art, as long as not new beyond this practicality
The thinking and scope of type technical scheme, should be included within the interest field required by the utility model.
