Abstract

The present invention relates to automobile technology, and is especially one series-parallel mixed power system. The present invention features the mixed connection structure of double motor and double clutch, the secondary motor for fast start of the engine, and the motor mode or the generator mode of both the main motor and the secondary motor. The secondary motor is connected to the output of the engine, the secondary clutch is set between the secondary motor and the main motor, and the main clutch is set between the gear box and the main motor. The mixed power system is similar to available internal combustion engine automobile in structure and has simple structure, compact arrangement, low manufacture cost, optimized running, braking energy feedback, low oil consumption, less harmful exhaust, excellent power performance and high running flexibility.

Description

technical field [0001] The invention relates to a system in the technical field of automobiles, in particular to a series-parallel hybrid hybrid power system. Background technique [0002] With the depletion of the world's oil resources and the rapid increase in the number of cars, not only the consumption of oil resources is further exacerbated, but also the environmental pollution to which human beings can survive may become increasingly serious. The development of energy-saving and environment-friendly hybrid vehicles has become a global One of the key points of the development of the automobile industry. The hybrid powertrain is a kind of vehicle powertrain that mixes the powertrain of the automobile engine. It is composed of a set of engine powertrain system and a set of electric drive powertrain system. . In order to enhance the versatility and platformization of the hybrid power system, the assembly of the hybrid power system has become the development trend of the ...
