Problems solved by technology
Since the variable-mode actuator will make the gear of the transmission assembly enter the neutral mode during the switching process of any two modes, the power of the transmission assembly will inevitably be interrupted at this time, which will be unfavorable to the smoothness and power of the vehicle. influences

The invention discloses a mode-changing actuating mechanism of a multimode coupling driving system for a vehicle. The mode-changing actuating mechanism is of a mode-changing drum-type structure, and comprises a mode-changing driving motor, a second-grade planetary gear reducer, a torsion damper, a mode-changing drum, a mode-changing drum shell, two mode-changing transverse rods, two mode-changing shifting rods and two mode-changing shifting forks. The input end of the second-grade planetary gear reducer is connected with the output end of the mode-changing driving motor. The input end of the torsion damper is connected with the output end of the second-grade planetary gear reducer, and the output end of the torsion damper is connected with the mode-changing drum. One end of the mode-changing drum is connected with the torsion damper, and the other end of the mode-changing drum is connected with the mode-changing drum shell. The mode-changing drum shell is fixed on a transmission system shell. The two ends of the mode-changing transverse rods are inserted into the transmission system shell. Two annular mode-changing grooves and a limiting groove are formed in the mode-changing drum. By means of the mode-changing actuating mechanism, mode switching of the multimode coupling driving system can be achieved, the continuity of power output can be kept in most mode switching processes of the multimode coupling driving system, and the power performance and the smooth-going performance of the vehicle are effectively improved.
Description
technical field [0001] The invention relates to a mode-variable actuator of a vehicle multi-mode coupling drive system, in particular to a mode-variable actuator of a coaxial hybrid hybrid vehicle drive system that can integrate centralized drive and distributed drive functions. Background technique [0002] Plug-in hybrid electric vehicle is one of the typical models of new energy vehicles. In terms of configuration, it can be divided into three types: parallel connection, series connection and hybrid connection; in terms of the power source of the wheels, it can also be divided into centralized type. There are two types of drives and distributed drives. In order to make full use of the respective advantages of centralized drive and distributed drive and avoid their defects, the applicant designed a multi-mode coupled drive system for vehicles in the early stage, the structure of which is as follows figure 1 As shown in the figure, the multi-mode coupled drive system can r...
