Abstract

The invention provides an automobile hybrid power system, and belongs to the technical field of automobiles. The problems that an existing automobile engine shakes during intervention and retreating, the fuel economy is poor, reverse gear power is insufficient under the condition that the electric quantity of a power battery is insufficient, and a transmission is difficult to arrange due to the too long axial distance are solved. The automobile hybrid power system comprises an engine, a generator, a planetary gear train, a power transmission shaft and a driving motor in transmission connection with the power transmission shaft, an output shaft of the engine is in transmission connection with a gear ring, and a rotating shaft of the generator is in transmission connection with a sun gear. The hybrid power system further comprises a sun gear clutch, a planet carrier clutch and a brake capable of braking the planet carrier, the planet carrier clutch is used for achieving transmission connection or disconnection between the planet carrier and the power transmission shaft, and the sun gear clutch is used for achieving transmission connection or disconnection between the sun gear and the power transmission shaft. The automobile hybrid power system has the advantages of being good in NVH performance, good in fuel economy, high in reverse gear power performance and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an automobile hybrid power system. Background technique [0002] In recent years, with the shortage of global oil resources and increasingly stringent domestic fuel consumption and emission regulations, there is an urgent need for research on more environmentally friendly, efficient and energy-saving automotive power systems. As a branch of new energy technology, hybrid vehicles have the advantages of better fuel economy and low emissions, and have become a new type of vehicle that is being developed. The key of the hybrid vehicle is the hybrid power system, and its performance is directly related to the overall performance of the hybrid vehicle. [0003] For example, a hybrid transmission and a hybrid vehicle disclosed in Chinese patent literature (application number: 201880086918.9; application publication number: CN111615466A), the hybrid transmission includes a first input ...
