Hybrid power driving device

Abstract

The invention relates to the field of transmissions and discloses a hybrid power driving device. The hybrid power driving device comprises a rear driving assembly and a front driving assembly, whereinthe rear driving assembly comprises a first motor and a transmission shaft, an output shaft of the first motor is configured to be selectively in transmission connection with an input shaft of an engine and the transmission shaft, the transmission shaft is used for driving a rear axle, the front driving assembly comprises a second motor, and the second motor can drive a front axle. The hybrid power driving device is advantaged in that multi-gear design of a traditional transmission is omitted, no matter the engine participates in driving when the vehicle speed is high the engine does not participate in driving when the vehicle speed is low, the engine is in the most economical working mode, oil consumption can be greatly reduced, problems of transmission performance and reliability caused by frequent gear shifting are solved, and switching of driving modes of front wheel independent driving, rear wheel independent driving and four-wheel common driving can be achieved through the reardriving assembly and the front driving assembly.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a hybrid driving device. Background technique [0002] Currently on the market, most of the improved hybrid drive devices based on automatic transmissions add a motor between the engine and the transmission, or connect a motor in parallel to a certain gear of the automatic transmission to achieve pure electric drive, braking energy recovery, and acceleration. Increase torque and other functions. [0003] However, this kind of hybrid driving device still needs to switch gears by switching dual clutches, and cannot rely on motor speed regulation, and the quality of gear shifting is not high, and software control is very difficult. At the same time, this scheme of improving the ordinary automatic transmission into a hybrid transmission cannot make the engine often work in the low fuel consumption area, and the reduction in fuel consumption is small; there are few hybrid drive modes, an...

Problems solved by technology

[0003] However, this kind of hybrid drive device still needs to switch gears by switching dual clutches, and cannot rely on motor speed regulation, and the quality of gear shifting is not high, and software control is very difficult

At the same time, this scheme of improving the ordinary automatic transmission into a hybrid transmission cannot make the engine often work in the low fuel consumption area, and the reduction in fuel consumption is small; there are few hybrid drive modes, and more fuel-saving modes cannot be realized

In addition, the emerging dual-motor hybrid solutions currently on the market are all arranged horizontally on the vehicle. Due to the limited lateral space of the vehicle, these solutions are often very compact, which makes the design and production of corresponding parts more difficult, and limited torque space
