The invention discloses a new energy vehicle power flexible transmission system, which comprises a transmission system body, wherein a clutch, a transmission, a driving gear, a transmission shaft, a coupling, a transmitting gear, a traveling motor, a synchronous belt reel, a synchronous belt, a synchronous motor, a release bearing, a clutch plate, a brake cable, a rocking bar, an engine, a transaxle and an installing support are arranged on the transmission system body. The system is reasonably designed, in the process of low-speed running or gear shifting, the engine and the synchronous motor coordinate with each other. The transmission system can avoid strong vibration generated in low-speed running or low-speed to high-speed transition process, accordingly the transition becomes more gentle, and the twisting vibration and noise of the transmission system can be greatly reduced, so that the gear-shifting impact to new energy vehicles during gear shifting is reduced, and the smooth transition of the gear shifting of the vehicles is increased.
Description
technical field [0001] The invention relates to the technical field of automobile transmission systems, in particular to a flexible power transmission system for new energy vehicles. Background technique [0002] The power transmission system or power transmission device is often used for variable speed and torque increase and power transmission of mechanical products. The power transmission device used in vehicles or general machinery in the prior art usually adopts the following structural form, a gearbox with shifting speed and torque increasing function, the input end of the gearbox is connected with the output end of the engine, and the output end of the gearbox is connected through the transmission shaft , belt drive, chain drive or gear drive pair, etc., transmit power deceleration and torque increase to the load. For motorcycles or general machinery, the engine and gearbox are generally made into an integrated structure, and the engine power of the integrated struct...
