Problems solved by technology

[0002] The existing hybrid power system is prone to power interruption during power output, especially in the process of shifting gears, and the hybrid power system takes up a lot of space, which in turn makes the interior space of the car body small, making it difficult to assemble the subsequent electrical structure. Convenient; at the same time, the existing hybrid system has high requirements on the motor, the cost of the motor increases, and the system efficiency is not high when used in multiple working conditions

Abstract

The invention provides a series-parallel hybrid power system based on two gearboxes. A hybrid power assembly is arranged conveniently, types of hybrid power products are expanded, power transmission continues, and the system is suitable for various complex working conditions. The system comprises an engine, a first motor, a first gearbox, a differential mechanism, a second motor and a second gearbox, the first gearbox is integrated with the second gearbox to form an integrated composite box, and an output shaft of the first gearbox is integrated with an output shaft of the second gearbox to form an output shaft of the integrated composite box; the output shaft of the integrated composite box is connected with a main reduction gear through a transmission shaft, the second gearbox further comprises an outer protruding input shaft, the outer protruding input shaft protrudes from one side of the integrated composite box and is connected with the power output part of the second motor, and an input shaft of the first gearbox protrudes from the other side of the integrated composite box and is connected with the output end of a motor shaft of the first motor.

Description

technical field [0001] The invention relates to the technical field of automobile power systems, in particular to a hybrid power system based on two gearboxes. Background technique [0002] The existing hybrid power system is prone to power interruption during power output, especially in the process of shifting gears, and the hybrid power system takes up a lot of space, which in turn makes the interior space of the car body small, making it difficult to assemble the subsequent electrical structure. Convenient; at the same time, the existing hybrid system has high requirements on the motor, the cost of the motor increases, and the system efficiency is not high when it is used in multiple working conditions. Contents of the invention [0003] In view of the above problems, the present invention provides a hybrid power system based on two gearboxes, which makes the layout of the hybrid power assembly convenient, expands the types of hybrid power products, and has continuous p...
