The invention relates to a composite planet row hybrid power device and a vehicle using the same. The combined type planet row hybrid power device comprises an engine, a motor and a planet row used for achieving confluence of the engine and the motor, wherein the planet row is a composite planet row provided with two stages of planet gears, a sun gear of the planet row is connected with the motorand locked or released by a sun gear locking clutch, a gear ring of the planet row is in transmission connection with the engine, and power of the planet row is outputted by a planet carrier. The combined type planet row hybrid power device is advantaged in that the planet row is a composite planet row provided with two stages of planet gears, the engine is directly connected with the gear ring, in a high speed state, a first motor is locked through a first locking clutch, the speed ratio of the engine to a power output end of the planet row is (k-1) / k, when a k value is 1.5-4, the speed ratiois about 0.33-0.75, compared with the prior art, an adjustable range of the speed ratio is large, the small speed ratio can be achieved, when the vehicle speed is high, for example, overtaking, the rotating speed of the engine cannot be too high.
Description
technical field [0001] The invention relates to a composite planetary row hybrid power device and a vehicle using the device. Background technique [0002] Hybrid electric vehicle is currently the most effective energy-saving vehicle solution, and its power system has three forms: series connection, parallel connection and hybrid connection. Series connection can realize the optimal control of the engine, but all the energy will be converted twice, and the loss is relatively large; parallel connection can achieve better transmission efficiency, but the mechanical connection between the engine and the output shaft cannot ensure that the engine is always in a better working area ; Hybrid connection can combine the advantages of series connection and parallel connection, and avoid the disadvantages of both. It is the most optimized configuration scheme among the three. [0003] The Chinese patent with the authorized notification number CN104175860B discloses a planetary hybrid...
