Abstract

The utility model relates to a bogie frame of a railway freight car, which comprises a wheel pair, side frames, a swing bolster, a damping device, bearing saddles and a spring, wherein, two support rods are intersected to pass through a prepared hole at the waist of the swing bolster; both ends of the support rods and two side frames are elastically connected into a whole body; both ends of the side frames are supported on wheel pairs through elastic shearing pads and the bearing saddles. The utility model can prevent the two side frames from generating rhombic displacement, can also make operation stable and can reduce the abrasion of wheel tracks; the utility model can improve the vertical and horizontal dynamic performance of the railway freight car, simultaneously improve the curve negotiating performance of the railway freight car, increase the critical speed of the snaking motion of the bogie frame and reduce the abrasion among the wheel tracks.

Description

A kind of railway goods train bogie

The utility model relates to a kind of railway goods train bogie, and is especially a kind of by utilizing bogie side frame elasticity to support in intersecting and the elastic shear pad improves the railway goods train bogie of bogie truck diamond resistant rigidity.

At present, the three-major-items roller bearing adapter stabilizer bar in the railway operation by bogie side frame, bolster, shock attenuation unit, wheel to and brake equipment etc. form.Car body and load thereof act on the bogie truck by the bolster cartridge, and implement the revolution by curve between cartridge up and down.The three-major-items roller bearing adapter stabilizer bar is because the contact between the bogie side frame bolster only depends on shock attenuation unit, so its diamond resistant rigidity is lower, and along with the abrasion of shock attenuation unit, " rhombus dislocation " easily takes place side frames." the rhombus dislocation " of truck side frame will cause the reduction of the critical speed of vehicle hunting, thereby reduce operation stability, strengthen wheel-rail wear.When vehicle moves on railway curve, be subjected to the adverse consequences of bogie side frame " rhombus dislocation " influence then even more serious.

The purpose of this utility model be to provide a kind of by utilize between the bogie truck side frames, be provided with a pair of elasticity of passing the bolster middle part intersect in strut bar, and the frame mode of elastic shear pad is set between bogie side frame and adapter, the constraint of shaking the head that unlocking wheel is right, overcome the adverse consequences that bogie truck " rhombus dislocation " causes, thereby reach the railway goods train bogie mechanism of improving the bogie truck diamond resistant rigidity.

The purpose of this utility model is achieved in that a kind of railway goods train bogie, comprise that wheel is to, bogie side frame, bolster, shock attenuation unit, adapter, spring, wherein two strut bars intersect the preformed hole that passes the bolster belly, strut bar two ends and side frames flexibly are connected as a single entity, and the two ends of described bogie side frame are bearing in wheel to last by means of elastic shear pad and adapter.

A kind of railway goods train bogie that the utility model proposes links by the supporting seat elasticity that is provided with on two strut bars and the bogie side frame, except that preventing that side frames from taking place can also reach and operate steadily " rhombus dislocation ", reduces the purpose of wheel-rail wear; Adapter is set on bearing, the elastic shear pad is set between adapter and bogie side frame, because the elastic shear spacer has certain vertical deflection, and the resilient suspension of formation bogie truck, according to vertical, vertical, the horizontal rigidity of elastic shear pad, produce to take turns right revolution, laterally, the constraint of longitudinal travel.Suitably select its parameter, can reach the bogie side frame favorable elasticity positioning action right with wheel, adapt to the friction speed requirement heavy with axle, thereby can improve the vertical and horizontal tractive performance of vehicle, and improve its curving performance simultaneously, improve the hunting critical speed of bogie truck, reduce the abrasion between the wheel track.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Below in conjunction with accompanying drawing and most preferred embodiment thereof the concrete structure that the utility model proposes is further described.

Extremely shown in Figure 6 as Fig. 1, a kind of railway goods train bogie that the utility model proposes, comprise wheel to 8, bogie side frame 1, bolster 2, shock attenuation unit 3, adapter 7, spring 4, wherein two strut bars 9,10 intersect the preformed hole 17 that passes bolster 2 bellies, strut bar 9,10 two ends and side frames 1 flexibly are connected as a single entity, and the two ends of described bogie side frame 1 are bearing in wheel on 8 by means of elastic shear pad and adapter 7.

The outside of above-mentioned bogie side frame 1 or inboard are provided with two supporting seats 12, supporting seat 12 is provided with a connecting column 11, described strut bar 9,10 both ends are provided with the collar, this collar is set on the above-mentioned connecting column 11, be provided with an elasticity guide 13 between the end collar of described strut bar 9,10 and the connecting column 11,14 of adjusting disks place between supporting seat 12 and the elasticity guide 13, overlap upper gasket 15 at last again, fastening nut 16 flexibly combines as a whole strut bar 9,10 and bogie side frame.

Above-mentioned connecting column 11 can be the taper connecting column, also can be cylindrical connecting column; Described elasticity guide 13 is complementary with connecting column 11, can be taper elasticity guide equally, also can be the Elastic Cylindrical guide.

Described bogie side frame 1 outside or the inboard supporting seat 12 of being arranged on is positioned near two-wheeled 8 centerline.

The elastic shear pad that is provided with between described bogie side frame 1 and the adapter 7 can be a splayed configuration elastic shear pad 6 according to the structure of bogie truck, also can be flush type elastic shear pad 18, implement the elasticity location by two locating dowel pins 19 between described bogie side frame and elastic shear pad and the adapter and connect.In use, when having than high camber, can adopt splayed elastic shear pad, only require its vertical, horizontal shear rigidity, can adopt the plane shear pad as single stage suspension as the needs single stage suspension.

Because bogie truck side frames 1 is the elasticity spanner, the anti-water chestnut deformation rigidity of bogie truck can reach 8 * 10 ⁶More than the NM/rad, the between centers shear rigidity reaches 2 * 10 approximately ⁶NM, and can adjust the predetermincd tension of elasticity guide as required, make bogie truck obtain desired critical speed, with the running stability of further raising bogie truck.
