The invention discloses an oil path system of a power coupling mechanism of a hybrid electric vehicle. The oil path system comprises a pressure oil path, a cooling oil path and a lubricating oil path. The power coupling mechanism comprises an input shaft (27) and an automatic gearbox. The automatic gearbox is provided with a clutch. The pressure oil path is connected with an electromagnetic valve and a clutch piston cavity. By the adoption of the technical scheme, in a quite narrow axial space, the internal spaces of all parts are sufficiently utilized through reasonable and ingenious layout, a hydraulic oil path, the lubricating oil path and the cooling oil path are integrated, the space requirement is reduced, sufficient cooling and lubricating of the mechanism are ensured, and the product service life is prolonged; the assembly dimension is shortened, so that the overall structure is more compact, the oil path system can be suitable for structure layout of more platform car types and is universal to various car types, and redesigning of oil paths is not required; and meanwhile, the cost can be significantly reduced, and popularization and promotion of technologies of a hybrid power system and the automatic gearbox are facilitated.
Description
technical field [0001] The invention belongs to the technical field of hybrid electric vehicle power system. In particular, it relates to an oil circuit system of a power coupling mechanism of a hybrid electric vehicle. Background technique [0002] As a means of transportation, automobiles play a very important role in modern industrial society. With the continuous increase of car ownership, people's demand for automatic transmission cars and hybrid cars is increasing day by day. In the domestic auto market and the mainstream auto markets in Europe, America, Japan and South Korea, more and more models have added automatic transmissions such as continuously variable transmission CVT, automatic transmission AT, hybrid transmission, etc. on the basis of the original manual transmission configuration. Gearbox configuration. [0003] For automatic transmissions, it is inevitable to use a large number of gears and clutches in a small space; for hybrid transmissions, it is nece...
