Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0044] like Figure 1-20 As shown, this embodiment provides a railway freight train running gear shaft end flexible transmission power generation device 1, comprising:

[0045] The base component 11 is used to be connected to the bearing end cover 21 of the axle end of the railway freight train running gear so as to rotate synchronously with the bearing end cover 21, that is, to rotate synchronously with the wheelset;

[0046] A right-angle transmission component 12, one end of which is transmission-connected to the base component 11, and is used to change the horizontal rotation into vertical rotation;

[0048] The power generation and storage component 14 is drivingly connected to the other end of the flexible transmission shaft and is used for power generation and power storage.

[0049] The base component 111 includes a base 1101 and a spline shaft 1102 . The base 1101 is used to be fixed to the bearing end cover 21 . One end of the spline shaft 1102 is fixed to the base 1101 , and the other end of the spline shaft 1102 extends in a direction away from the base 1101 .

[0050] The flexible transmission component 13 in this embodiment has a flexible transmission shaft that adopts the form of multiple seat bearing assemblies 1303 and universal joint couplings 1304 alternately connected in series in a rubber tube 1307. The seat bearing assembly 1303 adopts a seat bearing 130302 installed and fixed in the rubber tube 1307 for support and positioning. The shaft 130301 has no friction with the rubber tube 1307 during rotation, and the diameter of the universal joint coupling 1304 is also smaller than the outer diameter of the seat bearing 130302. Therefore, during the rotation transmission (torque transmission) in a bent state, the resistance is very small, which is a technical effect that other structures cannot bring.

[0052] The power generation and storage component 14 includes a housing and a bracket 1403, a generator 1401, a battery and a power storage management system 1404. The generator 1401, the battery and the power storage management system 1404 are installed in the housing, and the battery is electrically connected to the generator 1401 and the power storage management system respectively.

[0054] The flexible transmission component 13 further includes two plum blossom elastic couplings 1305 , and the flexible transmission shaft is respectively connected to the upper connecting shaft 1208 and the motor shaft of the generator 1401 through the two plum blossom elastic couplings 1305 .

[0055] The base 1101 is provided with through holes matched with the bolt holes on the bearing end cover 21, and the base 1101 can be fixed on the bearing end cover 21 through the original bolts 23 at the end of the running part shaft.

[0056] A pad 1215 is installed at the end of the spline sleeve 1201 away from the base 1101, and a bolt hole is provided at the end of the spline shaft 1102 away from the base 1101. The pad 1215 is provided with a through hole. A bolt passes through the through hole and is screwed into the bolt hole.

The base 1101 is provided with a through hole that matches the bolt hole on the bearing end cover 21. The base component 11 is fixed to the bearing end cover 21 at the shaft end by the original bolt 23 and the original anti-loosening gasket 22. When the train is running, the base component 11 will rotate with the bearing end cover 21 and form a power source, so that the spline shaft 1102 of the base component 11 will drive the spline shaft sleeve 1201 on the right-angle transmission component 12 installed with it to rotate synchronously.

[0059] Exemplarily, the right-angle transmission component 12 includes a spline sleeve 1201, an inner end cover 1202, a top screw 1203, an upper end cover 1204, a bearing pressure plate 1205, a hexagon socket screw 1206, a flat key 1207, an upper connecting shaft 1208, a limit ring 1209, a hexagon socket screw 1210, a bearing 1211, a spiral bevel gear 1212, a hexagon socket screw 1213, an outer end cover 1214, a gasket 1215, a hexagon socket screw 1216, a rubber plug 1217, a right-angle transmission component housing 1218, and a shaft seal 1219. The spline sleeve 1201 is fixed to the right angle transmission component housing 1218 through the inner end cover 1202, the bearing 1211, the hexagon socket screw 1213, and the shaft seal 1219. Since the bearing 1211 is provided between the spline sleeve 1201 and the right angle transmission component housing 1218, the spline sleeve 1201 can rotate freely. The upper connecting shaft 1208 is fixed to the right angle transmission component housing 1218 through the upper end cover 1204, the hexagon socket screw 1213, the bearing pressure plate 1205, the bearing 1211, the hexagon socket screw 1210, the limit snap ring 1209, and the hexagon socket screw 1206.

The two spiral bevel gears 1212 are respectively fixed on the upper connecting shaft 1208 and the spline sleeve 1201 through the top screw 1203 to form a vertical transmission match, thereby realizing the vertical transmission of the spline sleeve 1201 and the upper connecting shaft 1208. The outer end cover 1214 is fixed to the right-angle transmission component housing 1218 through the hexagon socket screw 1213. The cushion block 1215 is fixed to the spline sleeve 1201 through the hexagon socket screw 1216. The right-angle transmission component 12 is installed on the base component 11, and the spline sleeve 1201 is fitted with the spline shaft 1102, and then fixed with the hexagon socket screw 15, and then the rubber plug 16 is installed at the opening of the outer end cover 1214 to complete the complete installation process.

[0060] Exemplarily, the flexible transmission component 13 includes a flange seat 1301, a crimping tube 1302, a bearing assembly 1303, a universal joint coupling 1304, a plum blossom elastic coupling 1305, a hole elastic ring 1306, a rubber tube 1307, a hexagon socket screw 1308, and a rubber plug 1217. Among them, the bearing assembly 1303 includes a shaft 130301, a bearing 130302, a flat key 130303, and a shaft elastic ring 130304, and the shaft 130301 is fixed on the bearing 130302 through the shaft elastic ring 130304.

[0061] The length of the flexible transmission component 13 is determined according to various types of vehicle models and the installation positions of the power generation and storage components 14. The length of the rubber tube 1307 and the number of the seat bearing components 1303 and the universal joint coupling 1304 are determined according to the length. The shafts 130301 on a certain number of seat bearing components 1303 are connected to the universal joint coupling 1304 through the flat key 130303 to form a flexible transmission shaft of a certain length. The flexible transmission shaft is placed inside the rubber tube 1307. The seat bearing components 1303 at both ends of the flexible transmission shaft are connected through the holes. The elastic retaining ring 1306 is installed and fixed in the flange seats 1301 at both ends of the flexible transmission component 13. The flange seats 1301 at both ends of the flexible transmission component 13 are crimped and installed on the rubber tube 1307 through the crimping tube 1302 to form a whole; one end of the plum blossom elastic coupling 1305 is installed on the shaft 130301 of the seat bearing assembly 1303 at both ends of the flexible transmission component 13 through a flat key 130303, so the plum blossom elastic coupling 1305 at both ends can rotate synchronously, thereby realizing the complete assembly of a flexible transmission component.

The generator 1401 is fixed to the housing and the bracket 1403 by the hexagon socket screw 1402, and the battery and the power storage management system 1404 are fixed to the housing and the bracket 1403. The structure and installation method of the housing and the bracket 1403 can be customized according to different compartment structures.

[0063] When the train is running, the bearing end cover 21 on the running gear 2 drives the base component 11 to rotate, and a synchronous transmission is formed through the spline shaft 1102 of the base component 11 and the spline sleeve 1201 of the right-angle transmission component 12. The spiral bevel gear 1212 fixed on the spline sleeve 1201 and the upper connecting shaft 1208 forms a right-angle transmission (vertical transmission), and then the rotation of the upper connecting shaft 1208 of the right-angle transmission component 12 is transmitted to the generator 1401 of the power generation and storage component 14 through the flexible transmission component 13, so as to generate electricity. The generated electricity is stored in the battery of the power generation and storage component 14, and is ready to supply power to various detection and monitoring instruments.

[0064] The base component 11 is fixed to the bearing end cover 21 by the original bolts 23 and the original anti-loosening washers 22, and the spline shaft 1102 is ensured to be coaxial with the wheelset bearing. After the power generation and storage components are installed, the right-angle transmission component is quickly fixed to the base component by the hexagon socket bolts and covered with rubber plugs to complete the overall installation, thereby achieving rapid installation and removal. During the installation process, no changes were made to the bearing seat. Only the original bolts 23 and the original anti-loosening washers 22 were used to install the base 1101, and the structure of the existing freight train was almost unchanged. The base component 11 and the right-angle transmission component 12 are connected by the spline shaft 1102 and the spline shaft sleeve 1201 to achieve transmission connection and rapid installation and removal. The length of the flexible transmission component 13 is determined according to different carriages and can be appropriately bent and deformed. The installation and structural form of the power generation and storage component 14 are determined according to different carriages. The built-in right-angle transmission (vertical transmission) is adopted, which is realized by the spiral bevel gear 1212 to solve the problem of small installation space of the equipment body. Flexible transmission is used to solve the problem of complex installation space environment of the equipment body. The part of the whole device that needs to be sealed is realized by gasket-free sealant, and the protection level can reach IP67. The flexible transmission power generation device 1 at the axle end of the railway freight train running gear provided in this embodiment can meet the self-power supply requirements of various types of freight trains for detection and monitoring instruments, thereby realizing real-time monitoring. When the axle end temperature is too high, the movement is abnormal, the posture is abnormal, the road surface vibrates, etc., an alarm is issued in the first time when an abnormality occurs, and the ground personnel can be guided to conduct emergency investigation and processing of the alarm location.
