Planetary series-parallel system and vehicle using system

Abstract

The invention relates to a planetary series-parallel system and a vehicle using the system. The system comprises an engine, a first motor, a second motor, a front planetary row, a rear planetary row and a system output shaft, wherein an output shaft of the engine, the first motor, a first clutch and a second clutch are correspondingly connected, the first clutch and the second clutch are connectedwith a shell through first connecting mechanisms, the front planetary row is connected with the rear planetary row, and the rear planetary row, the second motor, a second connecting mechanism and thesystem output shaft are correspondingly connected. The system is provided with many working modes and therefore is high in working condition adaptability and high in oil saving potential. In addition, through the cooperative working of the clutches and the connecting mechanisms, the second motor can work around the base speed point at the high speed, and the weak magnetic loss caused by high-speed idling of the second motor is reduced, moreover, an engine overgear and an engine direct gear can be switched, the working condition adaptability is high, and the engine can be controlled to work inan efficient area in real time.

Description

technical field [0001] The invention relates to a planetary hybrid system and a vehicle using the system, and belongs to the technical field of planetary row hybrid power. Background technique [0002] In the face of increasingly serious environmental pollution and energy crisis, energy saving and environmental protection have become the theme of the times. Hybrid vehicles are favored by the public due to their excellent energy saving effects, unlimited mileage, and pure electric driving functions. Vehicle hybrid power systems are divided into three types: series, parallel, and hybrid. Among them, the series system needs to undergo secondary conversion of all energy, resulting in excessive energy loss, so it is relatively rarely used at present. The energy conversion of the parallel system is relatively small, but the engine cannot work at the highest efficiency point for a long time. However, the hybrid system using a planetary mechanism can solve the shortcomings of the p...
