Embodiment Construction

[0027] The present invention provides a bogie of a railway vehicle and a shaft end power generation device thereof. The shaft end power generation device is arranged under the bogie frame 1, which does not occupy the space above the frame 1. The structure is simple, and the space occupied is small. The structural influence of the frame 1 is small, and the optimization of vehicle design parameters can be realized.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can accurately understand the technical solution of the present invention.

[0029] For the convenience of explanation, this article takes the running state of the railway vehicle as a reference to define the direction, and takes the direction parallel to the running direction as the longitudinal direction. In the longitudinal direction, the direction in front of the running direction is the front, and the direction opposite t...

Abstract

The invention provides a bogie of a railway vehicle and an axle-head power generation assembly of the bogie. The axle-head power generation assembly comprises a power generator and a belt tension mechanism. The power generator is hung on a framework of the bogie and is connected with an axle by a belt, and the belt tension mechanism is arranged below the framework, is capable of longitudinally deforming and is longitudinally blocked between the power generator and a guide frame of a side bracket of the bogie in a pre-compression state, so that tension force can be provided for the belt. The bogie and the axle-head power generation assembly have the advantages that the axle-head power generation assembly is arranged below the framework of the bogie, without occupying spaces above the framework and is simple in structure, small in occupied space and little in influence on the structure of the framework of the bogie, and design parameters of the vehicle can be optimized; the belt tension mechanism is longitudinally blocked between the power generator and the guide frame of the bogie in the pre-compression state, the belt tension force which can vary along with conditions of the vehicle can be provided for the belt, and the bogie and the axle-head power generation assembly are simple in structure and small in occupied space and can assist in optimizing the design parameters of the vehicle.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a railway vehicle bogie and an axle end power generation device thereof. Background technique [0002] QT2 piggyback transport vehicle, the vehicle is a group of two, the two ends of the vehicle group are respectively equipped with hand brake devices and coupler buffer devices, the middle part of the vehicle group is connected by a joint coupler, the concave bottom car body load-bearing structure, the vehicle is equipped with Hydraulic and electrical systems. [0003] In order to meet the power supply requirements of transport refrigerated vehicles, this type of transport vehicle needs to be equipped with a bogie to provide power. [0004] The bogie with power generation device in the prior art adopts the principle of leverage, the fulcrum of the lever is in the middle, the upper end is the adjustment end, and the lower end is the action end; the spring is compressed or...
