Abstract

The invention provides a journal box built-in steering support framework, and relates to the technical field of power trucks of rail vehicles. The journal box built-in steering support framework comprises a cross transverse beam and side beams fixed to four corners of the transverse beam. A single air spring mounting seat is fixed in the middle of the transverse beam. A traction rod mounting cavity is formed in the single air spring mounting seat. A journal box built-in structure is adopted, so that the transverse beam of the framework becomes shorter, the rigidity of the framework is favorably increased, the self weight of the framework is favorably reduced, the dynamic performance is improved, the access to a small-radius curve rail is facilitated, the curve wheel track abrasion is reduced, and the curve passing performance is improved.

Description

technical field [0001] The invention relates to the technical field of power bogies for rail vehicles, in particular to an axle box built-in bogie frame. Background technique [0002] The bogie frame refers to the part of the rail vehicle that is responsible for carrying the car body and transmitting the weight of the car body, and is one of the most important key components of the rail vehicle. First of all, bearing the weight of the car body is the most basic requirement for the bogie frame. It can make self-adaptive adjustments for the rail vehicle running on the curve, so that the vehicle can run along the rail flexibly, safely and smoothly, and can reliably withstand the various loads acting on the vehicle. This kind of force is transmitted to the wheelset evenly. Secondly, in order to achieve effective acceleration and deceleration of the vehicle, the frame must identify the motion form of the bogie and the car body to prevent excessive relative displacement between t...
