Bogie frame

Abstract

The invention provides a bogie frame. The bogie frame comprises a first half frame and a second half frame which are shaped like an L; a movable area is formed at the connecting part of the first halfframe and the second half frame; and a shock absorbing mounting seat, a traction motor mounting seat, a gearbox mounting seat, a traction rod mounting seat and a magnetic track braking assembly mounting seat are also arranged on the bogie frame, wherein the shock absorbing mounting seat is used for a shock absorbing assembly to be mounted; the traction motor mounting seat is used for a traction motor to be mounted; the gearbox mounting seat is used for a gearbox to be mounted; the traction rod mounting seat is used for a traction rod to be arranged; and the magnetic track braking assembly mounting seat is used for a magnetic track braking assembly to be arranged. According to the bogie frame, the layout is compact and reasonable so that the stress is uniform and stress concentration is reduced; and moreover, a certain flexibility is realized; and through adoption of the bogie frame, a locomotive realizes good vertical comfort and anti-snaking capability during running on straight lines and curves.

Description

technical field [0001] The invention relates to the technical field of manufacturing and assembling of railway vehicles, in particular to a bogie frame. Background technique [0002] In the field of railway vehicle manufacturing and assembly technology, multi-articulated 100% low-floor modern trams are widely used due to their low acquisition costs. The bogie is one of the most critical components of multi-articulated 100% low-floor modern trams. It plays an important role in the bearing, traction, running and braking of the vehicle, which directly affects the running safety and riding comfort of the vehicle. It is one of the fields with the highest technical content, and it is also a key part to measure the technical level of the whole vehicle. As the main skeleton of the bogie, the frame is the core component of the bogie, which plays an important role in connecting various functional components, bearing loads and transmitting forces in all directions. The bogie and bogi...

Problems solved by technology

[0004] The cross beam and side beam based on the traditional bogie frame are connected by welding, so when the locomotive is running on uneven or curved roads, there is no space for the bogie frame to move at the connection between the cross beam and the side beam

In addition, the welding and assembly space of the beam is narrow, the design and manufacture are more difficult, and it is difficult to ensure the welding position, resulting in deformation of the weld seam during use. The above two situations will cause stress concentration inside the bogie frame, which is not conducive to railway construction. Safe and flexible driving at high speed

Therefore, the existing bogie frame cannot meet the requirements of the current railway vehicles
