Abstract: A transmission and a power system for use in a hybrid vehicle. A first ring gear or a first planetary frame is drivingly connected with an output gear of the transmission to serve as an output member, when either the first ring gear or the first planetary frame is drivingly connected with the output gear, the other one is connected with a casing of the transmission via a brake. A second clutch is configured as: when the brake is disengaged, the second clutch is engaged to make the rotational speed of the output member equal to the rotational speed of an input shaft. The transmission and the power system are structurally compact, work steadily, and effectively increase the acceleration performance of the hybrid vehicle.

Abstract: The present invention provides a power system for a hybrid vehicle, relating to the field of hybrid vehicles. The power system for a hybrid vehicle adopts a first planetary gear mechanism with two sun gears, the first sun gear rotates with an input shaft, the second sun gear and the input shaft are independent of each other, and the second sun gear achieves different motion states through a second brake or/and a second clutch, and cooperates with a first brake to provide different transmission ratios of four to six gears when an engine and motors are in driving, so that the power system is simple in structure and low in cost, and the fuel economy and acceleration dynamic performance of the power system are improved.

Abstract: A hybrid transmission and a vehicle having the hybrid transmission. An engine, a generator, and a motor are coaxially arranged; a first planetary gear set is separately connected to a crankshaft of the engine and a rotor of the generator; a clutch comprises a first driving end connected to a planet carrier of the first planetary gear set and a second driving end connected to a ring gear of a second planetary gear set, wherein the first driving end and the second driving end are involved in engagement and disengagement; a rotor of the motor is connected to a sun gear axle of the second planetary gear set. When the motor performs driving, the clutch is disengaged from the engine and the generator to avoid a drag resistance of the engine.

Abstract: 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.

Abstract: 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.
