Problems solved by technology

[0002] The main engine manufacturers of track equipment need to transport the test car body and the completed car body from the laboratory or production workshop to the special railway line. Generally, the car body is installed on a special simple bogie to complete the transportation. Most of the simple bogies used to transport car bodies in production workshops and special railway lines are simple in structure, and generally adopt rigid independent wheel-set structure types. The test car body is installed on the second series of car body rigidly supported by two columns on the first and second side of the simple trolley. The lateral adjustment clearance of the end face and the vertical column is small, and there is no positioning interface for the traction rod of the test car body, and its curve passing performance is poor. The safety during transportation is poor, especially when passing through a turnout or a small curve, it is easy to generate a large wheel-rail force, and it is easy to cause dangers such as derailment and car body sideslip
[0003] Previously, non-standard gauge car bodies were generally temporarily rebuilt with waste bogies when they were transported in and out of the laboratory, which was not safe and required temporary modifications

Embodiment 1

[0082] Such as Figure 21 with Figure 22 As shown, the transported car body adopts a single traction rod, such as CRH6-140 / CRH6-160 and other models. That is, a single traction interface module 22 is installed across the low position, and the installation height of the single traction interface module 22 is adjusted according to the installation height difference between the original air spring installation height of the CRH6 vehicle model and the secondary spring device 2 of the bogie, and Finally, a single traction interface module 22 is bridged and fixed on the two lower traction rod interface mounts 21 a on the same side by bolts.

Embodiment 2

[0084] Such as Figure 23 with Figure 24 As shown, the transported car body adopts low-position double traction rods, such as the Argentine EMU. When transporting the car body of this model, it needs to be installed on the two lower traction rod interface mounting seats 21a on the two beams 8, that is, the low position Install a low-position dual-traction interface module 23 symmetrically at an oblique angle, and adjust the installation height of the two low-position dual-traction interface modules 23 according to the installation height difference between the original air spring installation height of the Argentina EMU and the installation height of the secondary spring device 2 of this bogie , and finally fix the two low-position dual traction interface modules 23 on the two lower traction rod interface mounts 21a by bolts.

Embodiment 3

[0086] Such as Figure 25 with Figure 26 As shown, the transported car body adopts high-position double traction rods, such as Guangzhou Metro. When transporting the car body of this model, it needs to be installed on the two upper traction rod interface mounting seats 21b on the two beams 8, that is, the high position A high-position dual-traction interface module 24 is installed symmetrically at an oblique angle. According to the installation height difference between the original air spring of the Guangzhou Metro type and the installation height of the secondary spring device 2 of this bogie, high-position dual-traction interface modules 24 of different heights are selected, and Finally, the two high-position dual traction interface modules 24 are fixed on the two upper traction rod interface mounts 21b by bolts, which avoids the interference of the traction interface modules on the vehicle body when the conventional test vehicle body is transported.

Abstract

The invention relates to a bogie. The bogie comprises a framework, traction rods and a secondary suspension device. A vehicle body falls on the secondary suspension device; the traction rods are mounted between the vehicle body and a bogie body; the secondary suspension device and the framework are in sliding joint for adjustment of transverse span of the secondary suspension device; traction rod installing connector devices used for adjusting the installing height of the traction rods are mounted on the framework; and the ends of the traction rods are fixedly connected with the traction rod installing connector devices. According to the bogie, the demands of different vehicles for transverse span positioning of secondary springs are met by adjusting the transverse positions of two sets of secondary spring devices on sliding rails; meanwhile, the bogie is provided with the traction rod installing connector devices, so that traction device vertical and longitudinal positioning demands of the different types of vehicles are met; and the bogie can meet the requirement of conveying of vehicle bodies of the different types of vehicles.

Description

technical field [0001] The invention relates to a bogie, in particular to a bogie capable of transporting car bodies in production workshops and special railway lines, and belongs to the technical field of rail vehicle manufacturing.
