Abstract

The invention discloses a multi-mode electric drive axle based on clutch coupling, and belongs to the technical field of power assemblies. The multi-mode electric drive axle comprises a left half axle, a right half axle, a drive motor, a first transmission gear, a first clutch, a differential mechanism, a second transmission gear, a second clutch, a planetary transmission mechanism, a lock-up clutch and a third transmission gear. The first transmission gear is connected with the motor rotor and the first clutch and is meshed with the second transmission gear; the second transmission gear is connected with the sun gear and the second clutch; the lock-up clutch is connected with a vehicle body axle housing; the planet carrier is connected with the differential through the third transmission gear; the left half shaft penetrates through the motor rotor, the first transmission gear and the first clutch and is connected with the differential mechanism; the right half shaft is connected with the differential mechanism. Different coupling modes are achieved through combination and separation of the second clutch, the first clutch and the lock-up clutch, the differential distributes power, and power transmission is achieved. The integration degree is high, the dynamic property and economical efficiency are improved, and chassis specialization and power assembly serialization can be achieved conveniently.

Description

technical field [0001] The invention belongs to the technical field of powertrain, in particular to a multi-mode electric drive axle based on clutch coupling. Background technique [0002] The electric drive system technology of new energy vehicles is generally developing in the direction of power system integration and integration. Through the integrated design, on the one hand, the volume weight of the assembly can be further reduced, and the power, volume, and torque density of the system can be increased; It can improve the versatility of products and reduce development and production costs. [0003] At present, the electric drive axle of new energy commercial vehicles mostly adopts the scheme of motor matching AMT gearbox and motor matching reducer, and multi-shift actuators realize power coupling and transmission. The system integration degree is low, and the powertrain occupies a large space , heavy weight, low reliability of the shift actuator and high difficulty i...
