Bogie

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 that can transport car bodies on a production workshop and a special railway line, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] Each track equipment main engine manufacturer needs to transport the test car body and the finished 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 in production workshops and special railway lines are simple in structure and generally adopt rigid independent wheelset structure. The test car body is installed by two columns on the first and second positions of the simple trolley. On the end face, the column lateral adjustment gap is small, and there is no traction rod positioning interface for the test car body, its curve passing performance is poor, and even some bog...

AI Technical Summary

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
