Description
Technical field
The present invention relates to field of alloy preparation technology, and in particular to a kind of automobile-used rim of high-strength light track and its production
Technique.
Background technique
The track train of rail convertible car is the main movement device that vehicle moves on rail, so the design of rail wheel
Meet the size met when locomotive orbits, intensity and damping requirement.On the other hand, vehicle travels on highway,
Rail wheel also wants that fixation can be packed up, and cannot influence the normal work of rubber tire.Specifically, the design of rail wheel has following two points：
Track wheel system all parts size meets rail running requirement, and meets intensity requirement；Track wheel system will have outstanding subtract
Shake effect, in orbit when it is reliable and stable.
Since rail convertible car vehicle base space is limited, car body weight is limited by own wt and carrying platform weight, no
Equipment rail train bogie can be indiscriminately imitated completely.Therefore in addition to spring suspension equilibrium Full Vehicle System, impact is reduced.To wheel
Right, especially more stringent requirements are proposed for wheel.Wheel is to various stress in the total weight and movement for mainly undertaking vehicle.
So high to there is intensity to wheel, light-weight, resistance is small, and wearability waits require well.For this purpose, a kind of high-strength light track of the present invention
Automobile-used rim and its production technology, to meet the use demand of automobile-used rim.
Summary of the invention
In view of the above problems, the invention proposes a kind of automobile-used rim of high-strength light track and its production works
Skill, the tyre tread of rim are made into 5 degree of inclined-plane, can thus mitigate wheel to quality, convenient for passing through curve, moreover it is possible to wear tyre tread
It is relatively uniform, by reducing vehicle's center of gravity, reduces wheel to quality, improve the flexibility that rail wheel is entered the orbit.
In order to achieve the above purpose, the following technical solution is employed by the present invention：
