Abstract

The invention relates to a hybrid power module and a vehicle. The hybrid power module comprises a hybrid power speed changer, a first motor and a second motor, wherein the hybrid power speed changer comprises an input shaft connected with an internal combustion engine, a first planetary gear mechanism, a clutch device and an output shaft. The input shaft is connected with a planet carrier in a torsion resistance mode, and a first motor shaft of the first motor is connected with a sun wheel in a torsion resistance mode. A gear ring can transmit power to the output shaft, and the second motor can output the power to the output shaft through a second motor shaft, wherein the first end and the second end of the clutch device are correspondingly connected with the planet carrier and the gear ring in a torsion resistance mode, the first planetary gear mechanism, the first motor and the second motor are arranged coaxially, and the first motor and the second motor are located on the side, faraway from the internal combustion engine, of the first planetary gear mechanism. The second motor shaft is a hollow shaft, and the first motor shaft penetrates through the second motor shaft coaxially. The vehicle is provided with the hybrid power module.

Description

technical field [0001] The invention relates to a hybrid power module. The invention also relates to a vehicle comprising the hybrid module described above. Background technique [0002] In a current plug-in hybrid module, two electric motors are connected to the hybrid transmission, and the internal combustion engine is connected to the hybrid transmission through a hydraulic clutch, so that the hybrid module can realize multiple working modes. However, both the traction motor and the internal combustion engine can only provide a single gear, which is not enough to optimize the operating point of the electric motor or the internal combustion engine. The hydraulic clutch is engaged or disengaged according to the conditions of the internal combustion engine. For example, in road driving, the efficiency of the internal combustion engine is high and the vehicle speed is high. At this time, the hydraulic clutch is engaged, and the internal combustion engine outputs torque, whi...
