Abstract

The invention provides a bogie and a railway vehicle with the same. The bogie comprises a tread brake unit and a framework. The framework is provided with a bending area. The bogie further comprises a connecting structural part, a first connecting part and a second connecting part, wherein the connecting structural part is installed on the tread braking unit through the first connecting part. The connecting structural part is further installed on the framework through the second connecting part, and the second connecting part and the bending area are staggered. The bogie is connected away from the bending area, so that the bending area is easy to design, and the strength can be guaranteed.

Description

technical field [0001] The invention relates to a rail vehicle, in particular to a bogie and a rail vehicle with the bogie. Background technique [0002] The frame is an important load-bearing part in the bogie, and all systems need to be installed on the frame. The tread braking unit is connected to the corresponding mounting seat of the frame through fasteners. Since the existing tread brake installation positions are basically in the bending area of ​​the frame, this position is the stress concentration position of the frame. At the same time, when the vehicle is braking, the mounting seat bears all the braking load and the vibration load of the braking unit itself. , higher requirements on the strength of the mount. This brings great difficulties to the design of the bending area of ​​the frame and its structural strength. Contents of the invention [0003] Embodiments of the present invention provide a bogie and a rail vehicle having the bogie, so as to at least so...
