Abstract

The invention belongs to the field of new energy vehicles, and relates to a hybrid coupling system and a vehicle. The system comprises an engine, a generator, a driving motor, a first planet gear mechanism, a first brake, a second clutch and a first intermediate shaft, the first planet gear mechanism comprises a first sun gear shaft, a first sun gear, a first planet carrier, a first planet gear and a first gear ring, the engine is connected with the first sun wheel shaft, the generator is connected with the first sun wheel shaft or the first gear ring, the first sun gear is fixedly arranged onthe first sun gear shaft, the first gear ring is connected with the first brake, the first gear ring is connected with the first sun gear shaft through the second clutch, the first planet carrier isin speed reduction connection with the first intermediate shaft, the driving motor is connected with the first intermediate shaft, and the first intermediate shaft outputs power to wheels. The systemload can be reduced, multiple driving modes can be achieved, high transmission efficiency is achieved, and the power performance and economy of the whole vehicle are improved.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a hybrid power coupling system and a vehicle. Background technique [0002] The powertrain consists of the engine (internal combustion engine) and a transmission system consisting of a transmission, differential and drive shaft; its function is to provide the vehicle with the driving power required to drive the wheels. Internal combustion engines have a range of speeds and torques, and they work best within a small range where either fuel consumption is minimized, harmful emissions are minimized, or both. However, the actual road conditions are ever-changing, not only in the speed of the driving wheels, but also in the torque required by the driving wheels. Therefore, it is the primary task of the transmission to realize the optimal speed and torque of the internal combustion engine, that is, the optimal state of power, and a good match with the power state of the drive wheel....
