Railway wagon magnetic force driving power generation device

Abstract

The invention relates to a railway wagon power generation device, in particular to a railway wagon magnetic drive power generation device. The device comprises a generator and a bearing rear stopper assembly, the bearing rear stopper assembly comprises a bearing body, the bearing body is provided with a rear stopper, and the key technology is that a generator steel magnetic sheet is arranged in the generator, a rear stopper steel magnetic sheet is arranged on the outer wall of the rear stopper, and a protection ring is arranged on the outer wall of the rear stopper. The invention has the following beneficial effects: the steel magnetic sheet is arranged on the outer wall of the rear block composed of the bearing rear block, and the protective ring is arranged on the outer wall of the rear block provided with the steel magnetic sheet, so that the rear block can be unconditionally exchanged with the existing rear block of the axle system of the railway wagon, the original axle system structure is not changed, corresponding devices are not added, the traction resistance is not increased, and the weight of a single vehicle is not increased; and the magnetic lines of the permanent magnets are matched with the generator arranged on the bogie to form a loop nearby and are effectively coupled with the magnetic lines of the generator, so that the kinetic energy of the wagon is converted into electric energy to provide energy for electric equipment of the wagon.

Description

technical field [0001] The utility model relates to a magnetic drive power generation device for a railway freight car, which relates to a power generation device for a railway freight car, in particular to a device which can be used for magnetic drive power generation. Background technique [0002] At present, most railway freight cars at home and abroad are not electrified, and a few vehicles using ECP braking systems, refrigerated vehicles for cold chain transportation, and insulated vehicles are directly powered by locomotives, generator cars or batteries, and are in a centralized power supply mode. With the gradual development of the railway freight market and information technology, the concept of trying to convert the kinetic energy of the truck itself into electrical energy has gradually developed. There are some new products at home and abroad, such as the plunger pump power generation mode installed at the shaft end of the wheel axle system in Europe. The machine ...

Problems solved by technology

There are some new products at home and abroad, such as the plunger pump power generation mode installed at the shaft end of the wheel axle system in Europe. The machine works to generate power; this power generation mode increases the traction resistance for the entire truck, and at the same time, due to its separate configuration of plunger pumps and other equipment, the weight of the single vehicle also increases
