Description
Technical field
The present invention relates to wheel manufacturing technology fields, more particularly, to a kind of production method for wheel and wheel.
Background technology
Wagon wheel is one of important component of lorry, carries lorry guiding, mobile and carrying function, is straight
Connect the most critical component for being related to railway freight-car safety.In actual operation, the stress of wheel is more complicated, for tread
The freight car wheel of braking, the load born mainly have radially, axially with circumferential wheel rail force, tread brake thermic load, wheel shaft
Between active force and centrifugal force.
And in the design and manufacture of wheel, the disc shape of wheel has larger shadow to the structural strength and rigidity of wheel
It rings, so, in order to ensure the safety during wheel use, just to the web portion design requirement of wheel in design and manufacture
It is higher and higher.
But the manufacture intensity of existing wheel can't meet manufacture and require.
Invention content
The purpose of the present invention is to provide a kind of production method for wheel and wheels, to solve vehicle existing in the prior art
The technical issues of wheel intensity is unsatisfactory for intensity requirement.
Research, which is carried out, by the process manufactured to existing wheel is later discovered that the wheel that overseas market generally uses at present is equal
Rolled steel wheel is used, and rolled steel wheel and cast steel wheel, due to the difference of manufacturing process, maximum differential is exactly the weight of wheel.
Wherein, rolled steel wheel is processed using holotype, and the disc of cast steel wheel is direct cast form, and lap is separately processed
It forms；The rolled steel wheel weight of finished product can be far below the cast steel wheel weight of finished product.
Wheel is designed according to the requirement in CEN/TS 13979-2 technical specifications and strength check, wheel finite element
Analysis includes two parts of hot property and Mechanical Property Analysis, wherein the evaluation result of thermal performance analysis is rim for automobile wheel displacement
And residual stress, the evaluation result of Mechanical Property Analysis is Wheel Fatigue stress.
It being found after finite element analysis computation, the wheel rim shift value of the wheel thermal performance analysis of parabolic type disc is-
5.59mm is far more than the requirement of+3mm/-1mm required in CEN/TS 13979-2 technical specifications.
And the wheel of S type disc is reviewed, in the wheel rim displacement for after finite element analysis computation, finding its thermal performance analysis
Numerical value is+1.21mm, and the result of calculations such as residual stress and fatigue stress have also been satisfied by CEN/TS 13979-2 technologies rule
The requirement of model.
But because of the limitation of production technology, the wheel of casting technique production only has parabolic type disc shape, in order to
It is enough that wheel is produced in a manner of casting, and ensure the design strength requirement of wheel simultaneously, now provide the following technical solution.
A kind of production method for wheel provided by the invention, includes the following steps：
Cross section according to disc is the disc that parabolic type casts wheel, and in the inside radial plate surface and outside spoke of wheel
Plate face reserves machine-finish allowance；
Internal adradialia face and outside radial plate surface are machined.
In the above-mentioned technical solutions, in order to produce wheel in a manner of casting, while ensureing the design strength of wheel,
So first being come out the rough-cast of wheel with the shape of the cross section of disc parabolically type in casting, reserve simultaneously
Go out the allowance that can be processed in the inside radial plate surface and outside radial plate surface of wheel.
In this case, it will be able to combining the mode of mechanical processing to produce the cross section of disc in S by way of casting
The car wheel structure of type, to ensure that wheel rim shift value, residual stress and the fatigue stress of wheel accord with by the car wheel structure of S types
Relevant design standard is closed, ensures the safety that wheel uses.Wheel alleviates wheel after the processing of inside and outside radial plate surface simultaneously
Weight, and the larger presentation quality and dimensional accuracy for improving wheel web surface.
Further, in an embodiment of the present invention, the thickness that internal adradialia face is machined 3mm extremely
Between 8.8mm.
Further, in an embodiment of the present invention, the thickness that external adradialia face is machined 5mm extremely
Between 8.1mm.
Further, in an embodiment of the present invention, according to the disc that the cross section of disc is parabolic type casting wheel

Research, which is carried out, by the process manufactured to existing wheel is later discovered that the wheel that overseas market generally uses at present is equal
Rolled steel wheel is used, and rolled steel wheel and cast steel wheel, due to the difference of manufacturing process, maximum differential is exactly the weight of wheel.
Wherein, rolled steel wheel is processed using holotype, and the disc 1 of cast steel wheel is direct cast form, and lap separately adds
Work forms；The rolled steel wheel weight of finished product can be far below the cast steel wheel weight of finished product.
Wheel is designed according to the requirement in CEN/TS 13979-2 technical specifications and strength check, wheel finite element
Analysis includes two parts of hot property and Mechanical Property Analysis, wherein the evaluation result of thermal performance analysis is rim for automobile wheel displacement
And residual stress, the evaluation result of Mechanical Property Analysis is Wheel Fatigue stress.
Fig. 1 is the structural schematic diagram of parabolic type wheel web 1 in the prior art；It is found after finite element analysis computation,
The wheel rim shift value of the wheel thermal performance analysis of parabolic type disc 1 is -5.59mm, is far more than CEN/TS 13979-2 technologies
The requirement of+the 3mm/-1mm required in specification.
Thus, it is impossible to meet technology requirements for the wheel rim shift value of Parabolic wheel web 1, also just to wheel
Safety in utilization impact.
Fig. 2 is the structural schematic diagram of S types wheel web 1 in the prior art；And the wheel of S types disc 1 is reviewed, by having
After finite element analysis calculates, the wheel rim shift value of its thermal performance analysis is found as+1.21mm, and residual stress and fatigue stress
Etc. result of calculations be also satisfied by the requirements of CEN/TS 13979-2 technical specifications.
In this case, so that it may with by the way that 1 cross section of disc of wheel is designed to S types, to comply with design standard,
Meet security requirement.
But because of the limitation of production technology, the wheel of casting technique production is merely able to produce 1 shape of Parabolic disc
Shape, and 1 shape of Parabolic disc cannot meet the requirement of CEN/TS13979-2 technical specifications.
So in order to meet the requirement of CEN/TS 13979-2 technical specifications, the following technical solution is now provided.
