Abstract

The invention belongs to the technical field of vehicles and discloses a hybrid drive system and a hybrid vehicle. The hybrid drive system includes an engine, the first synchronous mechanism selectively abuts on the first gear pair and the second gear pair; the second synchronous mechanism selectively abuts on the third gear pair and the fifth gear pair, so that the fifth The rotation of the shaft is converted into the rotation of the third shaft, and the third synchronous mechanism is configured to selectively abut against the fourth gear pair; the first differential mechanism is connected to the third shaft and drives the rear wheels to rotate through the first drive shaft; the second The differential mechanism is connected to the sixth shaft and drives the front wheels to rotate through the second drive shaft; the engine drives the second shaft to rotate through the first shaft, which is used to generate electricity for the first motor, and the first motor can transmit the stored electric energy to the second The motor is used to make the second motor drive the fifth shaft to rotate. The hybrid drive system solves the problems of transmission performance and reliability caused by frequent gear shifting, and reduces processing difficulty.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid drive system and a hybrid vehicle. Background technique [0002] At present, most of the hybrids based on the improvement of automatic transmission add a motor between the engine and the transmission or connect a motor in parallel to a certain gear of the automatic transmission to achieve pure electric drive, braking energy recovery, acceleration and torque increase, etc. Function. [0003] In this way, gear shifting still needs to be achieved by switching the dual clutches, and the speed cannot be adjusted by the motor, and the shifting quality is not high, and software control is very difficult. At the same time, this method of improving the ordinary automatic transmission into a hybrid transmission cannot make the engine often work in the low fuel consumption area, the reduction in fuel consumption is small, and there are few hybrid drive modes, so more fuel-saving ...
