Description

Technical Field

[0001] The present invention relates to the technical field of mechanical environmental protection, and in particular to a driving system for converting heavy machinery from oil to electricity. Background Art

[0002] As global carbon emission requirements increase year by year, the national level implements a system that focuses on carbon intensity control and supplements with total carbon emission control, supporting qualified places, key industries, and key enterprises to reach carbon emission peaks first. Against this background, the green transportation transformation will greatly boost the demand for new energy transportation capacity, including new energy heavy trucks. Today's new energy heavy trucks are divided into pure electric heavy trucks and hybrid heavy trucks. Both pure electric heavy trucks and hybrid heavy trucks are newly designed and developed at the source of development and design, and finally new models are produced to replace the old fuel models on the market. The old fuel models on the market have to be scrapped in advance under certain specific conditions, resulting in a large amount of resource waste. The existing development methods and the final carbon emissions cannot actually achieve the purpose of emission reduction. The traditional heavy trucks that are replaced by new energy models and retired can only end up in the scrap factory, which greatly causes the waste of resources and products.

[0003] As described in the application number 202223250137.1, a hybrid power drive system suitable for converting heavy trucks from oil to electricity is completed in a way that includes retaining the intermediate drive axle of the traditional heavy truck and adding an electric drive front axle and an electric drive rear axle. The original intermediate drive axle needs to burn energy to drive the internal combustion engine to rotate so that the intermediate drive wheel drives the heavy truck to run. Without the electric drive front axle and the electric drive rear axle, the intermediate drive axle is mainly used, which will increase carbon emissions. After the improvement, the electric drive front axle and the electric drive rear axle are allowed to run, and the intermediate drive axle can be used or not, which reduces the carbon emissions of heavy trucks. In the traditional After adding an electric drive front axle and an electric drive rear axle to a heavy truck, the heavy truck can be operated in a pure electric mode by using the electric drive front axle and the electric drive rear axle. The traditional internal combustion engine may not work, and the two-in-one drive system and the electric drive front axle and the electric drive rear axle can drive the heavy truck to travel. The vehicle can also be operated in a pure fuel mode, in which the electric drive part does not work and the traditional middle drive axle works to drive the entire heavy truck. The vehicle can also be operated in a hybrid power drive mode, in which the internal combustion engine and the front and rear drive axles all work, and the middle and front and rear drive axles jointly provide driving power for the vehicle, thereby increasing the service life of the heavy truck and allowing for the reuse of the heavy truck.

[0004] Based on the retrieval of the above information, it can be seen that it is completely feasible to convert heavy machinery from oil to electricity. When the electric motor is used as the power, the speed of operation can be controlled without a gearbox. However, since the electric motor starts quickly, speed control is inconvenient and requires the accumulation of a lot of driving experience. In this process, relying solely on conventional brake structures will result in serious brake wear. For this reason, a drive system for converting heavy machinery from oil to electricity is proposed. While achieving efficient driving of the rotating shaft by the electric motor, rapid braking of the rotating shaft and the electric motor can also be achieved during braking, effectively reducing the wear rate of conventional brakes.
