Problems solved by technology

However, it also has disadvantages. It requires the power grid to continuously provide power, which is tantamount to increasing power consumption, and it also means increasing carbon emissions, because 50% of coal consumption is used for thermal power generation.
Moreover, power grids need to be laid along the road, which wastes resources, manpower and material resources

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, the train inertial power generation and power supply system includes a bogie 14 and a train power supply system. The bogie 14 includes an axle 1 that drives the wheels 2 to rotate. The axle 1 is provided with a first gear 5, and the first gear 5 and the axle 1 are detachable. Fixedly connected, the bogie 14 is also provided with an alternator 7, a gear box 21 and a clutch 6, and a second gear 20 is arranged in the gear box 21, and the rotation of the axle 1 drives the first gear 5 to rotate, and the first gear 5 and the second gear The gear 20 meshes to drive the gearbox 21 to run. The output end of the gearbox 21 is connected to the alternator 7 to drive the alternator 7 to generate electricity. The alternator 7 outputs electric energy to the train power supply system through wires.

[0023] The bogie 14 includes a side beam 3 and a cross beam 4 connecting the side beam 3, and an alternator 7 is arranged on the cross beam 4; the ...

Embodiment 2

[0026] The difference between this embodiment and Embodiment 1 is that the clutch 6 controls the on-off connection between the gearbox 21 and the second gear 20 .

Embodiment 3

[0028] The difference between this embodiment and Embodiment 1 is that the 25kV, 50Hz single-phase alternating current supplied by the catenary is first introduced into the train transformer through the pantograph. Then, after the transformer of the train transforms the voltage to the electrical equipment such as the converter 12 and the inverter 11, the alternating current is directly supplied to the traction motor. The traction motor drives the wheel 2 to roll. When the train runs at a speed of 250km / h or more and enters normal operation, the inertia generated drives the wheel 2 to roll, and the wheel 2 drives the axle 1 to drive the permanent magnet power generation through the combination of the gearbox 21 and the clutch 6. Machine 7 rotates and generates electricity.

Description

technical field [0001] The invention relates to a vehicle, in particular to a train inertial power generation and power supply system. Background technique [0002] In the construction of existing EMUs (high-speed passenger trains), electrified railways are currently powered by 110kV or other kV high-voltage power systems to substations, and then sent to catenary after voltage transformation. The electric locomotive raises the pantograph to introduce the 25kV, 50Hz single-phase AC power supplied by the catenary into the train transformer. Then, after the voltage is transformed by the transformer of the train to the electrical equipment such as converters and inverters, the alternating current is directly supplied to the entire train. However, it also has disadvantages. It requires the power grid to continuously provide power, which is tantamount to increasing power consumption, and it also means increasing carbon emissions, because 50% of coal consumption is used for therma...
