Abstract

The invention relates to a general welding steering support. Wherein, it comprises frame, wheels, axial suspender, vibration reducer, and basic brake. The suspender has axial tank pad plate. The vibration reducer has inner round spring and outer round spring; the top of spring has spring cap; two sides of spring are arranged with suspension rings; the lifter is between the suspender and spring; the frame is mounted with empty-heavy vehicle adjuster which uses valve lifter to mount adjust valve, and under the adjust valve, the suspender is mounted with sensor valve base.

Description

Welding bogie

(1) technical field:

Welding bogie relates to the railway freight traffic device, especially the bogie truck used of railway truck.

(2) technical background:

Existing welding bogie, its shock attenuation unit and empty and load brake equipment performance are not satisfactory, and framework structure science not, have influenced the applicability of bogie truck.

(3) summary of the invention:

The problem to be solved in the present invention provides a kind of shock attenuation unit and empty and load brake equipment functional at above deficiency exactly, framework structure science, the welding bogie that applicability is good.Its technical scheme is: it comprises that framework, wheel to, axle box suspension gear, shock attenuation unit and foundation brake rigging, have the axle box backing plate on the axle box suspension gear.Shock attenuation unit has interior coil spring and outer coil spring, is provided with spring compressor on the spring top, is provided with suspension ring in the spring both sides, is provided with the holder body between axle box suspension gear and spring.Empty and load brake equipment also is installed on framework, and empty and load brake equipment is to hang by valve install to adjust valve on framework, is adjusting below the valve, on the axle box suspension gear sensing valve seat is being installed.Its gordian technique is that the occipital beam of framework comprises lower cover and upper cover plate, is provided with curb girder web and body bolster diaphragm between lower cover and upper cover plate.

Compared with prior art the present invention has the advantage of the following aspects:

1. have good commonality, can be applicable to multiple car body, as: Venezuela's container flat car, the common flatcar of Venezuela, Venezuela's foodstuff hopper wagon and Venezuela's box car etc.

2. unsprung weight is little, and wheel-rail force is low.

3. adopt equal strength design-calculated box-shaped welded frame, diamond resistant rigidity is big, and wheel is to elasticity location, hunting critical speed height.

4. adopt the Li Nuoer shock absorber, improve operation stability.

5. adopt VTA valve empty and load brake equipment, can satisfy vehicle requirement to braking force under empty wagons and two kinds of different conditions of loaded vehicle.

6. simple in structure, be easy to make and safeguard.

(5) specific embodiment:

Referring to accompanying drawing, the present invention includes H type welded frame 2, wheel to 1, axle box suspension gear 3, shock attenuation unit 5 and foundation brake rigging 4, framework (2) has the occipital beam, and axle box backing plate 12 is arranged on the axle box suspension gear 3.Shock attenuation unit 5 has interior coil spring 8 and outer coil spring 7, is provided with spring compressor 10 on the spring top, is provided with suspension ring 11 in the spring both sides, is provided with holder body 9 between axle box suspension gear 3 and spring, constitutes the Li Nuoer friction shock absorber.VTA valve empty and load brake equipment 6 is installed on framework 2, and empty and load brake equipment 6 is to hang 13 by valve install to adjust valves 14 on framework 2, is adjusting below the valve 14, on the axle box suspension gear 3 sensing valve seat 15 is being installed.

Framework section structure form can be a box-structure, also can be meridosternous structure or other section structure forms.The framework of box section structure is shown in Fig. 6-8, and the occipital beam of framework comprises lower cover 18 and upper cover plate 19, is provided with curb girder web 17 and body bolster diaphragm 20 between lower cover 18 and upper cover plate 19.Between curb girder web 17 and body bolster diaphragm 20, be provided with stiffening plate 16, with the intensity of deep framing.Can satisfy the heavy operating needs of 12t-40t axle after adjusting the wheel set bearing of corresponding framework structure intensity and apolegamy different model.Distance between backs of wheel flanges is 1360 ₀ ^{+ 2}Mm can be by adjusting rail and the track switch of different distance between backs of wheel flanges with the gauge of suitable different model.Wheel tread adopts UIC S1002 type tread, can be by the various difform wheel treads of rotary cut to be fit to the rail and the track switch of various different models.Shock attenuation unit is one-sided sharp Nore friction shock absorber or bilateral Li Nuoer shock absorber, and it all has attenuation to vertical and lateral vibration, its stable performance, and friction force is subjected to the influence of extraneous climatic conditions and abrasion state less, and wearing surface is easy in reparation.Take turns right longitudinal register rigidity owing to vertical no gap between axle box and framework has increased, improved operation stability.The empty and load brake equipment of VTA valve empty and load brake equipment or other form can satisfy vehicle requirement to braking force under empty wagons and two kinds of different conditions of loaded vehicle.
