Hybrid power module and hybrid power vehicle

Abstract

The invention relates to a hybrid power module and a hybrid power vehicle. The hybrid power module comprises an input shaft used for being connected with an internal combustion engine, an output shaftused for transmitting a torque to a drive axle, a first motor, a first rotating shaft, a second motor, a second rotating shaft, a gear ring, a first gear, a second gear, a third gear, a first torquetransmission device and a second torque transmission device, wherein the gear ring and the first gear are meshed with each other; and the second gear and the third gear are meshed with each other. Thesecond rotating shaft is designed as a hollow shaft, and the first rotating shaft is arranged inside the second rotating shaft. The first gear is arranged on the first rotating shaft in an anti-rotation mode, the second gear is arranged on the second rotating shaft in a sleeving mode, the third gear is arranged on the output shaft in an anti-rotation mode, and the first torque transmission devicecan selectively connect the gear ring with the input shaft in the anti-rotation mode. The second torque transmitting device may selectively connect the second rotating shaft with the first rotating shaft in the anti-rotation mode. The hybrid power vehicle comprises the hybrid power module.

Description

technical field [0001] The invention relates to the technical field of vehicles. In particular, the invention relates to a hybrid module. The invention also relates to a hybrid vehicle comprising the above-mentioned hybrid module. Background technique [0002] In current hybrid vehicles, multiple working modes of the hybrid vehicle can be realized through a hybrid module provided with two electric motors, ie a traction motor and an integrated starter generator, in cooperation with an internal combustion engine. In this case, the internal combustion engine of the hybrid vehicle is connected into the hybrid module via the disconnect clutch. The separating clutch is engaged or disengaged depending on the state of the internal combustion engine. For example, in road driving, due to the high speed of the vehicle, the efficiency of the internal combustion engine is high. At this time, the separation clutch is engaged, and the vehicle is driven by the power of the internal combu...

AI Technical Summary

Problems solved by technology

This type of hybrid vehicle has good city driving economy, but it is not suitable for highway driving, the reason is that the vehicle cannot be directly driven by the internal combustion engine, the electric motor always works in the power generation mode or the traction mode to adjust the internal combustion engine operating point, and The dynamic performance of such hybrid vehicles in ECVT mode is also not ideal
