摘要： The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system mainly includes an engine, a first motor, a second motor, a first planetary gear mechanism, a second planetary gear mechanism, a first input shaft, a first clutch, a brake, and a second clutch. Since the second motor is connected to the first input shaft through the second planetary gear mechanism, the planetary gear mechanism can reduce the speed of the second motor and increase the torque to effectively reduce the size of the second motor or improve the acceleration performance of the vehicle. Since the first clutch between the first input shaft and the engine is disengaged when driven by the second motor, the drag resistance of the engine is reduced, and the fuel economy of the vehicle is improved.

摘要： A dual-clutch automatic transmission having seven forward gears and one reverse gear, wherein a seventh-gear driving gearwheel, a first-gear driving gearwheel, a fifth-gear driving gearwheel and a third-gear driving gearwheel are individually and fixedly arranged on a first input shaft, a fourth-gear driving gearwheel and a second-gear driving gearwheel are individually and fixedly arranged on a second input shaft, driven gearwheels respectively and correspondingly engaged with the driving gearwheels are rotatably supported on the first output shaft and the second output shaft. The fourth-gear driving gearwheel is also used as a sixth-gear driving gearwheel, and the gear sets of other gears are not shared, which is conducive to decrease the overall axial length of the transmission, facilitates full vehicle arrangement, and prevents the speed ratio ranges of other gears from being influenced by sharing of these gear sets to adapt to more vehicle models. In addition, the arrangement of a parking ratchet wheel is optimized in the present invention, the stress distribution on the output shafts can be more even, and thus the stability is improved and the service life is prolonged.
摘要翻译：一种具有七个前进档和一个倒档的双离合器自动变速器，其中七档齿轮传动齿轮，第一档驱动齿轮，五齿轮驱动齿轮和三档传动齿轮分别固定地设置在第一输入轴，第四齿轮驱动齿轮和第二齿轮驱动齿轮分别固定地布置在第二输入轴上，分别与从动齿轮相配合，主动齿轮可旋转地支撑在第一输出轴上，第二输出轴。第四档驱动齿轮也用作第六档驱动齿轮，其他齿轮的齿轮组不共用，有利于减小变速器的总体轴向长度，有利于整车配置，并防止速度其他齿轮的比例范围受到这些齿轮组共享的影响，以适应更多的车型。此外，在本发明中优化了停车棘轮的布置，输出轴上的应力分布可以更均匀，从而提高了稳定性，延长了使用寿命。

摘要： Provided is an axially-limited guide device applied in a parking mechanism. The parking mechanism includes a parking pawl and a parking shift fork that is axially movable. The guide device includes a parking bracket assembly and a guide block. The guide block is configured to be slidably engaged with an execution member at an end of the parking shift fork to allow for a relative rotation of the parking pawl and a rotary shaft. The parking bracket assembly is configured to axially limit the parking pawl and guide the parking shift fork. The parking bracket assembly includes a limiting portion abutting against the guide block. The limiting portion is configured to limit an axial movement of the guide block when the execution member at the end of the parking shift fork is axially disengaged from the guide block. Also provided are a parking mechanism and an automobile.
