Abstract

The invention discloses a railway manifest bogie which comprises a framework, four sets of tumbler type axle box positioning devices, two sets of wheel pairs, a swing bolster and a set of basic braking devices. A U-shaped cavity in the middle of a side beam of the framework is provided with a two-line rubber-metal pad installation platform and provides installation space for the swing bolster and the two-line rubber-metal pad, it is ensured that the size of the manifest bogie and a car body connector can meet the using requirement of an existing wagon; the swing bolster adopts a two-line rubber-metal pad installation base of a forge piece for replacing a welding structure with actual stress exceeding allowable stress, and the strength of the portion is improved; by adopting an axle box elastic suspension system, high-frequency impact of the car during high-speed running is effectively reduced; by additionally arranging a series of rubber springs with the bearing and vibration reduction functions, the perpendicular rigidity of the heavy car working condition bogie is improved, and the variable rigidity of the framework bogie axle box body is achieved.

Description

technical field

[0001] The invention belongs to the technical field of rail vehicle freight cars, and in particular relates to a bogie for railway express freight cars. Background technique

[0002] Heavy-duty and fast are the development direction of railway freight cars. According to the development of domestic railway freight and the requirements of railway technology policies, it is necessary to develop a fast railway freight car with a running speed of 140km / h-160km / h and an axle load of no more than 18t. As an important part of fast railway freight car, the bogie of fast freight car directly affects the running speed and load capacity of the vehicle.

[0003] At present, the frame-type fast truck bogies mainly include fast truck bogies with shaking table structure Linoer shock absorber positioning, rubber pile guide column positioning fast truck bogies without shaking table bolsters, and rubber spring positioning without shaking table bolsters. Fast freight car bogie,...
