Abstract

The invention discloses a clutch-based planetary gear shifting electric drive axle, and belongs to the technical field of power assemblies, and the clutch-based planetary gear shifting electric drive axle comprises a left half shaft, a right half shaft, a drive motor, a first transmission gear, a second transmission gear, a third transmission gear, a fourth transmission gear, a planetary transmission mechanism, a lock-up clutch, a clutch and a differential mechanism; the first transmission gear is connected with a motor rotor and is meshed with the second transmission gear; the second transmission gear is connected with the third transmission gear and is meshed with the fourth transmission gear; the fourth transmission gear is connected with a sun gear; a planet carrier is connected with the differential mechanism; the left half shaft penetrates through the motor rotor, the fourth transmission gear and the middle of the sun gear. Power is outputted to the sun gear, different coupling of the power is achieved through combination and separation of the clutch and the lock-up clutch, and the differential mechanism distributes the power to the two half shafts. The driving motor, the clutch and the axle are integrated, the transmission shaft is omitted, the power system is more compact, and chassis specialization and power assembly serialization can be achieved conveniently.

Description

Technical field [0001] The present invention belongs to the field of power assembly, in particular to a clutch planetary electric drive bridge. Background technique [0002] The new energy automotive electric drive system technology is generally developed in the integrated direction of power system. Through integrated integrated design, one hand can further reduce the volume weight of the assembly, improve the power, volume, and torque density of the system; on the other hand, the NVH level of the electric drive assembly is improved by the matching and refinement of the electric drive assembly. Chemical and batch production, improve product versatility and reduce development and production costs. [0003] At present, the new energy commercial electric drive bridge is multi-motor matching AMT gearbox, motor matching reducer scheme, and multi-shifting actuator realizes power coupling and transmission, and its system is low, and the power assembly is large. Large weight, low reliabi...
