Steel spring structure, bogie and rail vehicle with same

Abstract

The invention relates to a steel spring structure, a bogie and a rail vehicle with same. The steel spring structure comprises an upper positioning groove and a lower positioning groove, a steel springassembly is arranged between the upper positioning groove and the lower positioning groove, the steel spring assembly comprises a steel spring inner ring and a steel spring outer ring, and a first rubber shock pad is arranged in the upper positioning groove. A second rubber shock pad is arranged in the lower positioning groove, and a first extending end and a second extending end are matched to form a vertical stop. The bogie comprises a bogie support and mounting seats, a steel spring structure is arranged between the bogie support and the mounting seats, a traction rod is arranged between the bogie support and a railway vehicle body, and an anti-nodding device, a vertical shock absorber and a transverse shock absorber are arranged between each mounting seat and the railway vehicle body.And a transverse stopper is arranged between each mounting seat and the bogie support. The purpose of double supporting is achieved through the steel spring assembly, transverse displacement can be achieved through the vertical stop block, impact and vibration are reduced, and riding comfort is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle manufacturing, in particular to a steel spring structure for secondary suspension, a bogie and a rail vehicle with the bogie. Background technique [0002] The straddle-type monorail vehicle is supported, stabilized and guided by a single rail, and the car body adopts a rail transit system that rides on the rail beam with rubber tires. The straddle-type monorail vehicle is characterized by strong adaptability, low noise, and small turning radius , Strong climbing ability, can better adapt to the complex terrain and landform environment. [0003] At present, the bogies of straddle monorail vehicles mainly include Chongqing Hitachi double-axle monorail bogies and Bombardier single-axle monorail bogies, both of which belong to the category of conventional monorail bogies. Since straddle monorail vehicles do not use primary suspension The rubber wheel plays the role of the first series of spring...

Problems solved by technology

[0003] At present, the bogies of straddle monorail vehicles mainly include Chongqing Hitachi double-axle monorail bogies and Bombardier single-axle monorail bogies, both of which belong to the category of conventional monorail bogies. Since straddle monorail vehicles do not use primary suspension The rubber wheel plays the role of the first series of springs. The straddle monorail car mainly uses empty springs and hourglass springs as the second series of springs to match the rubber wheels. In traditional rail transit vehicles, the first and second series mainly use steel springs, rubber springs and Air springs are used in conjunction with each other. Due to the need for joint use, the structure becomes complicated and the cost is high. If steel springs are used alone, although the cost is reduced, the corresponding safety is reduced
