Problems solved by technology

The bogie adopts a boom-type shaker structure, and the bolster is located at the lower part of the frame, which is not conducive to the arrangement of the lower limit of the bogie, and the risk of the bolster falling off the track is relatively high. The shock absorber makes the longitudinal positioning stiffness of the bogie too large, the curve passing performance is not good, and the use of wearing parts increases the maintenance cost

Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] Such as figure 1 , figure 2 The railway express freight car bogie shown includes a frame 200 , four sets of pivoting arm type axle box positioning devices 100 , two sets of wheel sets 500 , a bolster 300 and a set of foundation braking device 600 .

[0060] Such as image 3 As shown, the frame 200 includes a pair of side girders 240 of a double-web box structure, a pair of cross girders 250 of a round steel pipe structure, and a pair of curved longitudinal girders 280 . combine Figure 4 As shown, the side sill 240 includes a side sill double web 241 , a side sill upper cover 242 and a side sill lower cover 243 . In this embodiment, the middle part of the side beam 240 is a U-shaped cavity 244 concave downward, and the bottom plane 244a of the U-shaped cavity 244 is welded with a secondary rubber pile installation platform...

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,...
