Three-shaft type double-clutch hybrid power system

Abstract

The three-shaft type double-clutch hybrid power system is characterized in that a first main reduction driving gear, an outer input shaft driven gear and an inner input shaft driven gear are fixed on a first intermediate shaft, the outer input shaft driven gear is constantly meshed with an outer input shaft driving gear, and the inner input shaft driven gear is constantly meshed with an inner input shaft driving gear; the main reduction driven gear is fixed on the differential mechanism assembly, and the main reduction driven gear is constantly meshed with the first main reduction driving gear; the TM motor assembly is constantly meshed with the main reduction driven gear, or the main reduction driven gear is fixed to the first main reduction driving gear. The mode that the two clutches are integrated is adopted, one clutch corresponds to one gear, and the two sets of clutches are separated and combined synchronously. Meanwhile, a synchronizer is omitted on the basis, the problem of gear shifting power interruption in the vehicle running process is effectively solved, meanwhile, the structure is simplified, cost is reduced, and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a three-shaft dual-clutch hybrid power system. Background technique [0002] Compared with the multi-gear parallel shaft hybrid transmissions currently on the market, all are single clutch + synchronizer shifting or dual clutch + synchronizer shifting. After the single clutch is disconnected, it is necessary to wait for the synchronizer shifting to complete before combining. , the structure will inevitably have power interruption during the shifting process; dual-clutch shifting solves the power interruption, but still requires a synchronizer to complete the shifting, which requires the transmission to add a shifting system, which greatly increases the structure. Complexity, correspondingly brings the problem of rising cost and reducing reliability. Contents of the invention [0003] The invention provides a three-shaft dual-clutch hybrid power system, which co...

[0002] Compared with the multi-gear parallel shaft hybrid transmissions currently on the market, all of them are single clutch + synchronizer shifting or dual clutch + synchronizer shifting, single clutch After disconnection, it is necessary to wait for the synchronizer to complete the gear shift before combining. This structure will inevitably cause power interruption during the gear shift process; dual-clutch shifting solves the power interruption, but the synchronizer is still required to complete the gear shift. It is necessary to add another gear shifting system to the transmission, which greatly increases the complexity of the structure, and correspondingly brings about the problems of increased cost and reduced reliability
