Suspension type rail vehicle and bogie thereof

Abstract

The invention discloses a bogie of a suspension type rail vehicle. The bogie comprises a bearing bent beam with an L-shaped structure and a bearing cross beam, wherein the bearing bent beam is provided with a rail buckling part used for buckling with a rail from the upper portion of the rail, a swing stopping abutting part used for abutting with the rail from the bottom of the rail to be matched with the rail buckling part to prevent a vehicle body from swinging, and a vehicle body connecting part used for being positioned below the rail to bear the vehicle body; and the bearing cross beam is integrally connected with one end, close to the rail buckling part, of the bearing bent beam, and is provided with a shaft bridge connecting part which is fixedly connected with a shaft bridge. The bearing bent beam is provided with the rail buckling part, the swing stopping abutting part and the vehicle body connecting part, and the bearing bent beam is integrally connected with the bearing cross beam, so that the bogie is of an integral structure, the structure is simple and compact, and the bearing capacity is high; and the swing stopping abutting part limits the bogie to only slide relative to a rail and prevents a car body from swinging, so that the bogie is simple in structure and good in safety. The invention also discloses the suspension type rail vehicle comprising the bogie.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a bogie for a suspended rail vehicle. The invention also relates to a suspended rail vehicle comprising a bogie as described above. Background technique [0002] The car body of the suspended rail vehicle is located under the track, which has the advantages of long service life, flexible operation lines, and land saving, so that the suspended rail vehicle can alleviate urban traffic problems without expanding the existing road facilities in the city, and is more suitable The development needs of public transportation in modern cities have broad prospects for development. [0003] Existing suspended rail vehicles include asymmetrically suspended rail vehicles. Asymmetrically suspended rail vehicles usually include bogies, primary longitudinal suspensions, secondary suspensions, car bodies, tracks and wheel sets. The wheel set assembly includes two wheels arranged longitudinall...

AI Technical Summary

Problems solved by technology

Apparently, the bogie of the existing asymmetric suspended rail vehicle needs to be connected with other parts besides the load-carrying body, so the structure is relatively complicated

[0004] However, there are still many deficiencies in the bogies of the existing asymmetric suspended rail vehicles. For example, the connecting parts used to connect the parts usually adopt split connection, which leads to the complicated structure of the bogies, relatively weak carrying capacity and low safety. Threatened; another example, the unreasonable cooperation between the bogie and the track, resulting in a greater risk of swinging the car body relative to the track, and relatively poor safety

[0005] Therefore, the structure of the bogie of the existing asymmetric suspension rail vehicle is more complicated and the safety is relatively poor
