Abstract

The invention belongs to the technical field of hybrid electric vehicles, and particularly relates to a hybrid power transmission device. A commercial vehicle hybrid power transmission device with a retarding function comprises a battery pack, a motor controller, a brake resistor, a first motor, a second motor, brakes and a planetary sub-confluence mechanism, wherein the first motor, the second motor, the brakes and the planetary sub-confluence mechanism are coaxially arranged. The planetary sub-confluence mechanism includes a power dividing planetary row, a first deceleration planetary row and a second deceleration planetary row. The brakes comprise a first brake and a second brake. The power dividing planetary row is connected with an input shaft, a rotor of the first motor and an outputshaft, and the first deceleration planetary row and the second deceleration planetary row are both connected to a rotor of the second motor and the output shaft. The first brake and the second brakeand the first deceleration planetary row and the second deceleration planetary row constitute a two-speed retarding mechanism. The commercial vehicle hybrid power transmission device utilizes the motors to realize braking energy recovery, the brake resistor is arranged to ensure that the braking power of the motors is consumed when the battery SOC is high, and the retarding brake function is stillachieved during long-time brake.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular to a hybrid transmission device. Background technique [0002] Hybrid transmission technology is an important means of energy saving and emission reduction, and major automobile manufacturers are actively developing it. Toyota's THS hybrid technology has a good fuel-saving effect. The planetary mechanism is used for power splitting to ensure that the engine always works in the economical range, but the planetary mechanism has higher requirements. The hybrid power system in series form can ensure the engine works in the economical range, and is suitable for working conditions such as frequent start and stop, severe load changes, and urban driving. However, due to its narrow transmission ratio range, it is not suitable for commercial vehicles. [0003] CN105452039 A discloses a vertical dual-motor hybrid power transmission device, which adopts a single planetary row...
