250 tons of depressed center flat cars of described speed-raising, top, described totally-enclosed welded great underframe corner is that arc transition, bottom are bending angle transition, the bent angle upper end of described great underframe connects respectively with block seat and Goods binding adapter plate, the carrying surface two ends of described great underframe are provided with the fixing hole of using of goods, the carrying surface both sides of described great underframe are provided with rope hook, and described great underframe two ends have protruding spherical body center plate and body side bearing.
250 tons of depressed center flat cars of described speed-raising, described little underframe comprises the box central sill, described central sill connects with Shen Liang, described Shen Liang connects with crossbeam, described central sill is respectively with protruding spherical body center plate, concave sphere truck center plate and often contact double-acting elastic side bearing and the connection of cartridge anti-drop device, and described crossbeam connects with body side bearing.
250 tons of depressed center flat cars of described speed-raising, described A type bogie truck comprises A type framework, described A type framework connects with the normal double-acting elastic side bearing that contacts, described A type framework connects with the concave sphere truck center plate, described A type framework lower end connects with shock attenuation unit, described shock attenuation unit below connects with the journal box spring suspension gear, and described A type framework lower end connects with foundation brake rigging and rolling bearing system.
250 tons of depressed center flat cars of described speed-raising, described Type B bogie truck comprises the Type B framework, described Type B framework upper end contacts double-acting elastic side bearing and the concave sphere truck center plate connects with normal respectively, described Type B framework lower end connects with shock attenuation unit, described shock attenuation unit below connects with the journal box spring suspension gear, and described Type B frame underneath connects with foundation brake rigging and rolling bearing system respectively.
This technical scheme has following beneficial effect:
1. the 250 tons of depressed center flat car great underframes that raise speed adopt full-closed structure, and top, corner is that arc transition, bottom are bending angle transition, has effectively alleviated deadweight, has improved load-carrying, has improved capacity greatly, satisfies railway speed-raising truck, heavily stressed demand for development.Traveling portion adopts 4E axle welded frame formula bogie truck; The two-stage side bearing adopts normal contact double-acting elastic side bearing; The highest commercial running velocity 120km/h of empty wagons (loaded vehicle is handled by " super rule ").
2. great underframe carrying surface length 10000mm, carrying surface height to the top of rail 1050mm (empty wagons) enlarges the cargo transport protection face, the commonality of performance depressed center flat car; The great underframe two ends are provided with block seat, Goods binding adapter plate, and the carrying surface two ends establish that goods is fixing use the hole, and rope hook is established in the carrying surface both sides, satisfies the reinforcing requirement of different goods, reduces the provisional stiffener that welds when using, and alleviate or avoid damage to car body.
3. under existing " railroad bridge calibrating standard " CR live loading standard, this car is fully loaded, when the sky runner wagon is carried additionally in front and back, and by bridge minimum speed 〉=41km/h, it is overweight to be no more than one-level.
The main parts size of bogie truck, coupler and draft gear and brake system by reliability design and perfect technology, realized life-span management.Prolong the period of inspection and repair, cancellation is supplementally taken and is repaiied journey, has reduced the repair and maintenance cost.This car was finished the test of first sample car in 2006, and had carried out sound intensity, dynamics test.Test shows that this car has reached the design-calculated intended purposes basically.
