Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0030] As described in the background technology, when existing power generation devices obtain power from train axles, they are generally installed at the ends of the axles. Figure 1 and Figure 2 As shown, the shaft end generator 200 is only fixed on one side, and can be simplified as a cantilever beam in structure. However, the cantilever beam will aggravate the vibration under vibration conditions, which will have an adverse effect on the generator structure. In addition, the shaft end needs to be disassembled and modified when installing the generator, which has high construction requirements.

[0031] Based on the above reasons, this embodiment provides a device for obtaining power generation from the axle through rolling friction, such as Figure 3-Figure 8 As shown, it includes a suspension 103, a positioning wheel set, a driven wheel 104 and a generator 109.

[0032] The suspension 103 is located between two opposite train wheels and is fixedly connected to a base frame of the train, which does not rotate with the train axle. The base frame is a bogie bolster;

[0033] The positioning wheel set includes a plurality of positioning wheels 106 rotatably mounted on the suspension 103 , the positioning wheels 106 are located at the periphery of the train axle and fit the train axle 300 ;

[0034] The driven wheel 104 is drivingly connected to the rotor of the generator 109 , and the generator 109 is mounted on the suspension 103 via an elastic member 105 ; preferably, the elastic member is a constant force spring.

[0035] The driven wheel 104 is in contact with the train axle, and the train axle 300 drives the driven wheel to rotate through roller friction, and the rotation of the driven wheel drives the generator to generate electricity.

[0036] The above-mentioned technical features can realize the acquisition of power from the train axle through rolling friction, so as to generate electricity through the power; it solves the problems of limited space when installing the power generation equipment on the axle end of the traditional freight train, heavy and unbalanced load on the axle end, inconvenient installation and need to modify the vehicle.

[0037] In order to store electricity generated by the generator, in one embodiment, a storage battery 108 electrically connected to the generator is installed on the suspension 103 .

[0038] In order to solve the problem of synchronous rotation of the suspension and the train axle, in one embodiment, the suspension includes a rotation-stopping bracket 107, which is fixedly connected to the base frame.

[0039] In order to facilitate the installation of the positioning wheel, the driven wheel and the battery, in one embodiment, the suspension 103 also includes an upper suspension 102 and a lower suspension 101, wherein the train axle 300 passes through the upper suspension 102, the upper suspension 102 is fixedly connected to the base frame through a stop bracket 107, the lower suspension 101 is fixedly installed under the upper suspension 102 by screws, and the battery 108 is installed on the lower suspension 101.

[0040] For example, Figure 4 and Figure 5 As shown, the upper suspension 102 is bent and has a mounting groove in the middle. An upper cover 1021 is fixedly installed at the upper end of the mounting groove. The positioning wheel 106 is installed in the mounting groove through a rotating shaft. The generator is installed in the mounting groove. The driven wheel is connected to the generator and is located on both sides of the upper suspension.

[0046] The rotation of the train axle drives the driven wheels to rotate, and the rotating driven wheels drive the corresponding generator to generate electricity.

[0047] Specifically, according to the number of driven wheels, the specific method of arranging the driven wheels on the periphery of the train axle is:

[0048] The driven wheel is mounted between two train wheels through a suspension and is positioned using a number of positioning wheels mounted on the suspension and adapted to the train axles;

[0049] The suspension is connected to the bogie bolster via a rotation-stop bracket.

[0050] The above power generation method does not require modification of the train vehicle.
