Description

混动变速器总成及具有其的车辆Hybrid transmission assembly and vehicle having the same 技术领域Technical Field
本申请涉及车辆技术领域，具体而言，涉及一种混动变速器总成及具有其的车辆。本申请要求于2022年12月02日提交至中国国家知识产权局、申请号为202211538488.4、发明名称为“混动变速器及具有其的车辆”的专利申请的优先权。The present application relates to the field of vehicle technology, and more specifically, to a hybrid transmission assembly and a vehicle having the same. The present application claims priority to a patent application filed with the State Intellectual Property Office of China on December 2, 2022, with application number 202211538488.4 and invention name “Hybrid Transmission and Vehicle Having the Same”.
背景技术Background technique
包括纯电和混动在内的新能源汽车，是当下汽车行业发展的主流，各大汽车厂商也在抓紧布局。相较于燃油车，新能源车的突出优势是节能、环保以及使用成本优势，对于动力***要求更紧凑的布局及更高的传动效率。变速器内部用于支撑轴系高速旋转的轴承，如果没有很好的润滑***支撑，将极大降低使用寿命，引起用户抱怨。市场上主要采用的润滑方式有飞溅润滑和主动润滑。New energy vehicles, including pure electric and hybrid vehicles, are the mainstream of the current automotive industry, and major automakers are also working hard to develop them. Compared with fuel vehicles, the outstanding advantages of new energy vehicles are energy saving, environmental protection, and cost advantages. They require a more compact layout and higher transmission efficiency for the power system. The bearings used to support the high-speed rotation of the shaft system inside the transmission will greatly reduce their service life if they are not well supported by the lubrication system, causing user complaints. The main lubrication methods used in the market are splash lubrication and active lubrication.
飞溅润滑的缺点在于，相较于减速器，混动变速器的轴系较多，油液很难到达所有需要润滑的齿轮和轴承，特别是布置在变速器上部的轴系，极大增加壳体润滑结构的复杂性及制造成本。The disadvantage of splash lubrication is that compared with the reducer, the hybrid transmission has more shaft systems, and it is difficult for the oil to reach all the gears and bearings that need lubrication, especially the shaft system arranged at the top of the transmission, which greatly increases the complexity of the housing lubrication structure and the manufacturing cost.
主动润滑主要有机械泵及电子泵两种，机械泵润滑油量与齿轮转速相关，在低速下，齿轮转速低，容易导致轴承润滑效果不良；电子泵增加整车成本，消耗电池能量，增加整车能耗，降低车辆续驶里程。There are two main types of active lubrication: mechanical pumps and electronic pumps. The amount of lubricating oil in a mechanical pump is related to the gear speed. At low speeds, the gear speed is low, which can easily lead to poor bearing lubrication. Electronic pumps increase the cost of the entire vehicle, consume battery energy, increase the energy consumption of the entire vehicle, and reduce the vehicle's cruising range.
