The specific embodiment
The following stated content is the detailed description of in conjunction with the accompanying drawings the present invention being done, and should not be understood that it is limitation of the invention.
Seeing also Fig. 1, is linear stator iron shoe and expansion joint scheme drawing thereof.As can be seen from the figure ferrimagnetism stator stirrup strap 1 is equidistantly arranged along straight line.The upper and lower side of stator stirrup strap 1 is fixed (as using electric welding) respectively on the reinforced rib 2 that ferromagnetic material is made, thereby forms the linear stator track.When the linear stator track is double when making guided way, between per two stator stirrup straps 1, inlay nonferromugnetic material in 3, its surface is identical with stator stirrup strap surface elevation and smooth smooth.Ferromagnetic material can be the material that carbon steel, silicon steel, corrosion-resistant steel, cobalt, nickel or its alloy etc. have permeance.Nonferromugnetic material can be non-magnet materials such as cement concrete, copper, aluminium or polytetrafluoroethylene.
Stride the Lu Liang junction overhead two, generally all be provided with Temperature Joint, therefore, the linear stator track must be established expansion joint 4 herein.Expansion joint 4 is the interspersed structure of convex-concave, right side convex portion 4a correspondence left side concave portion 4b.The design of the two-part interspersed degree of depth of convex-concave, to carry out with the temperature modulus of temperature deformation and the factors such as summer in winter maximum temperature difference value of linear stator trackwork environment according to material, promptly determine according to the temperature modulus of material and summer in the winter maximum temperature difference of linear stator track environment for use.When high temperature when (summer), the linear stator elongation, insertion portion increases; When low temperature (winter), linear stator shortens, and insertion portion reduces, but it is uninterrupted continuously to remain expansion joint.Relevant is the technology that those skilled in the art can understand according to temperature difference design, does not launch to describe at this.
Seeing also Fig. 2, is linear stator iron shoe rail and magnetic motor rotor corresponding relation schematic top plan view.As can be seen from the figure, magnetic motivation 5 is by non magnetic basic 5a, wheel shaft 5b and the p-m rotor 5c composition of taking turns.P-m rotor 5c installs equally spacedly along the periphery of the basic 5a of wheel.
