Dual-clutch transmission for hybrid power

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0021] like figure 1 As shown, the dual clutch transmission for this hybrid power includes an electric motor 8, an engine 1, an input shaft 7, an input shaft 2 5 and an output shaft 14, the input shaft 1 7 is connected to the output end of the electric motor 8, and the input shaft 2 5 and The output ends of the engine 1 are connected, and the output end of the engine 1, the first input shaft 7, the second input shaft 5 and the output end of the electric motor 8 are all coaxially arranged. The input shaft one 7 is fixed with a driving gear one 4, the input shaft two 5 is sleeved with a driving gear two 9, the input shaft one 7 and the input shaft two 5 are connected by a one-way clutch 6, and the input shaft two 5 is connected with the engine. 1 is connected by a double clutch one-phase, the double clutch one packs the clutch one 2 and the second clutch 3, the clutch one 2 and the driving gear two 9 are fixed circumferentially, the clutch one 2 and the clutch two 3 are connected with the input shaft, The second clutch 3 is also connected to the output end of the engine 1 . The output shaft 14 is provided with a dual clutch 2 and a driving gear 3 that can be connected with the differential 12. The dual clutch 2 includes a clutch 3 10 and a clutch 4 11. Both sides of the dual clutch 2 are respectively provided with a driven gear 1 15 and a slave gear 1 . The second driven gear 16, the third clutch 10 and the driven gear one 15 are circumferentially fixed, the clutch four 11 and the driven gear two 16 are circumferentially fixed, and the driven gear one 15 and the driven gear two 16 are sleeved on the output shaft 14. , and the driven gear one 15 and the driven gear two 16 mesh with the driving gear one 4 and the driving gear two 9 respectively, the driven gear one 15 and the driven gear two 16 are respectively circumferentially fixed with the double clutch two, and from The diameter and number of teeth of the first driven gear 15 are larger than those of the second driven gear 16 , the diameter and number of teeth of the second driven gear 16 are larger than those of the third driving gear, and the diameter and number of teeth of the first driving gear 4 are smaller than those of the second driving gear 9 .

[0022] The working principle of the device is as follows: when the vehicle is in a parking state, both the first dual clutch and the second dual clutch are in a normally open state, that is, in a disengaged state, and do not transmit power. Only when the corresponding clutch is engaged, the power is transmitted. When the vehicle starts, the input shaft 1 7 is mainly driven by the motor 8 to rotate, and the engine 1 drives the input shaft 2 5 to provide the corresponding hybrid power supply for the input shaft 1 7 through the one-way clutch 6, using the dual input mode. When the vehicle enters a steady state, the one-way clutch 6 is switched, and the engine 1 works alone through the double clutch to drive the input shaft to rotate. At this time, the engine 1 works in a steady state, and the economy is the best. When the vehicle is braked, once the dual clutch is disconnected, the output shaft 14 reversely charges the electric motor 8 through the second dual clutch. When the vehicle reverses, the input shaft 7 is mainly driven by the electric motor 8 in the reverse direction to realize the reverse gear.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention pertains can make various modifications or additions to the described specific embodiments or substitute in similar manners, but will not deviate from the spirit of the present invention or go beyond the definitions of the appended claims range.
