As above-mentioned basic scheme, the compound axle box locate mode that between journal box body and truck frame, adopts steel spring and rubber steady arm to combine, this locate mode combines the advantage of pivoted arm locate mode and laminated rubber spring mode, can synthetically realize longitudinal traction, cross spacing and vertical carrying, and no creep, the no gap of less rigidity axle box location when reaching long-term high-speed cruising is provided on vertical and not have the abrasion characteristics.
Comparatively the selection scheme of You Huaing is, described rubber steady arm is an integral type elastomeric element of being made through sulfuration by steel plate and rubber layer.
For under the high-speed cruising state, realizing spacing and fastening at the rubber steady arm, be provided with an annular groove in the inner top side of described locating bush, the interior snap ring shutoff in the embedding annular groove is on the top of rubber steady arm.
Comparatively the improvement project of refinement is, is connected with the location gland between described limit plug and truck frame, and dowel bolt upwards connects limit plug and location gland.
For further improving the spacing and fastening effect at steel spring, liner has a location packing ring between location gland and steel spring upper end, and liner is made up of a rubber pad between the lower end of steel spring and the locating bush.
Comparatively the scheme of You Huaing can be, it is an integral type elastomeric element of being made through sulfuration by steel plate and rubber layer that rubber pad is formed.
For improving compound axle-box positioning device integral installation performance, the upper end of described compound axle-box positioning device is installed on truck frame by bolt.
In addition, between journal box body and truck frame, be provided with vertical oil-pressure damper, in order to the decay guideway vehicle vertical vibration that bogie truck takes place under the high-speed cruising state.
In sum, the compound axle-box positioning device of the utility model guideway vehicle has the following advantages and beneficial effect:
1, the locate mode that adopts steel spring and rubber steady arm to combine has made full use of the characteristics that robustness, energy storage speed are fast, the life-span long and the rubber steady arm is vertical, lateral stiffness is big of steel spring, can satisfy the requirement of guideway vehicle high-speed cruising fully.
2, adopted take into account vertically, the adjustable rubber steady arm of lateral stiffness, realizes that higher axle box is vertical, lateral stiffness, guarantee to have less vertical stiffness.
3, critical speed, the reasonable distribution one that has improved bogie truck is load capacity, thereby reduces the stress level of steel spring, avoids the endurance failure of steel spring.
4, can guarantee that but enough operational spaces are arranged under the car, be applied to substance, diaxon or multi axle truck.
