Bogie secondary suspension device and bogie

Abstract

The invention relates to a bogie secondary suspension device and a bogie. The bogie secondary suspension device comprises two groups of secondary spring devices; the two groups of secondary spring devices are arranged on a frame of the bogie; each of the two groups of the secondary spring devices is slidably connected with the frame, so that the transverse span between the two groups of the secondary spring devices is adjusted. The bogie secondary suspension device and the bogie have the advantages that the requirements on transverse span positioning of secondary springs of different automobiles can be met, so that the bogie can meet transportation of different automobile types and different automobile bodies, therefore the universality is stronger, and the operation safety can be guaranteed.

Description

technical field [0001] The invention relates to a bogie, and also relates to a secondary suspension device installed on the bogie, which belongs to the technical field of rail vehicle manufacturing. Background technique [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 system 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...

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
