Description

TECHNICAL FIELD

[0001] The present application relates to the field of locomotive technology, in particular to a new energy locomotive axle control bogie transmission device and transmission method, which is suitable for GK type locomotive. BACKGROUND

[0002] According to statistics, about 2 / 3 of the annual oil consumption in China is consumed in the field of transportation. The greenhouse gas emissions of transportation tools powered by fossil energy combustion are an important source of atmospheric greenhouse gases, and more than half of the newly added greenhouse gases in the atmosphere come from the combustion of fossil fuels. Therefore, controlling the greenhouse gas emissions of transportation tools is an important measure to control carbon emissions.

[0003] Railway traction energy consumption accounts for more than 50% of all energy consumption in rail transit, and realizing low-carbon and carbon-free of railway traction energy is the key link of railway energy saving and emission reduction. At present, the main modes of railway traction energy include diesel and electricity. In countries with relatively low electrification rates, fuel accounts for a higher proportion of traction energy than electricity. Even in countries with relatively high electrification rates, various engineering vehicles, maintenance vehicles, construction vehicles, shunting locomotives and some locomotives for special purposes still use internal combustion engines for traction, resulting in fuel accounting for about half of the total energy consumption. In China, electrified railways have developed rapidly, and by the end of 2019, the electrification rate of China's railways has exceeded 70%. Even so, there are still a large number of diesel locomotives serving in steel enterprises. These old car models have poor economy, high energy consumption and serious pollution, and are difficult to meet the current demand for carbon reduction production. These diesel locomotives in steel enterprises cause serious air pollution and a very poor working environment, directly affecting the health of workers. At the same time, a large number of old diesel locomotives in steel enterprises will face scrap, and implementing green remanufacturing of diesel locomotives not only realizes the recycling of a large number of old diesel locomotive equipment resources, but also saves energy and protects the environment, forming a new industry with considerable social and economic benefits. Therefore, promoting green remanufacturing of diesel locomotives and using new energy instead of fuel is one of the important ways for steel enterprises to realize clean and low-carbon railway transportation.

[0004] Modern locomotives (such as GK type locomotives) generally adopt the structure of a bogie running gear. The bogie on the locomotive is equivalent to a person's two legs, so it is also called the running gear of the locomotive. Since the bogie structure running gear is suitable for high speed, high power, various driving modes and axle type, as well as various required elastic suspension modes and basic braking modes. Therefore, the modern locomotive running gear basically adopts the structure of the bogie.

[0005] The bogie is mainly composed of a frame, a spring device, a connecting device, a wheel set and a shaft box, a driving device, a basic braking device and the like. The bogie can bear all the weight on the car body, including the car body, the frame, the power device and various auxiliary devices and motor electrical facilities, etc., and can ensure the necessary adhesion between the wheel and the rail to generate a circular traction force at the wheel and rail contact to achieve the traction of the train. The frame is the skeleton of the bogie and bears and transmits vertical and horizontal forces; the spring device ensures uniform distribution of axle load and ensures smooth operation of the locomotive; the wheel set and the shaft box directly transmit the weight of the locomotive to the steel rail; and the driving device transmits the traction power of the locomotive power device to the wheel set.

[0006] At present, the driving of the GK-type locomotive is mainly to transmit the traction power to the wheel set through the universal shaft and the axle gear box by the internal combustion engine to achieve the traction of the train. The GK-type locomotive body usually has two bogies, and each bogie usually has two axle gear boxes. With the dual pressure of depletion of oil resources and serious environmental pollution, it has become the consensus of the international community to develop new energy, and the consumption of transportation energy is one of the main sources of environmental pollution and global greenhouse effect. Therefore, the transportation energy power system has changed the locomotive using the internal combustion engine. Therefore, a new energy locomotive axle control bogie transmission device needs to be designed and applied to the existing old locomotive group to meet the normal operation of the locomotive while realizing the energy reduction and emission reduction of the locomotive group.
