Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing:

[0035] The purpose of the present invention is to provide a new type of hybrid power system, that is, to provide a hybrid power system with double planetary row as the electromechanical coupling device, so as to realize the electronic integration of the hybrid power system. The continuously variable speed function controls the engine to work in the best fuel economy zone, improves the fuel economy of the vehicle, and achieves ultra-low emissions. At the same time, it overcomes the current heavy dependence of the hybrid electric vehicle on the motor, which requires a large motor to provide sufficient driving force In addition, the planetary dual-mode oil-electric hybrid system described in the present invention can fully realize the parallel mode due to the addition of the clutch, and obtain more optimized comprehensive transmission efficiency and vehicle fuel economy.

Abstract

The invention discloses a planetary type dual-mode petrol-electric parallel-serial hybrid power system, and aims to solve the current problems that the parallel-serial hybrid power car greatly depends on a motor, and the current planetary type parallel-serial hybrid power car cannot totally realize a parallel mode so as to cause the transmission efficiency not to be optimized enough. The system comprises an engine, a motor I, an inverter, a supercapacitor, a motor II, a front planetary row, a back planetary row, a clutch, a system output shaft and a system input shaft, wherein engine is connected with the system input shaft by virtue of a coupling, the front planetary row is sheathed in the right end of the system input shaft, the motor I is freely sheathed in the left end of the system input shaft, the right end of the motor I is in spline connection with the left end of the front planetary row, the clutch is in spline connection with the front planetary row, the front planetary row is in spline connection with the system output shaft, the back planetary row is sheathed in the system output shaft, the motor II is freely sheathed in the right end of the system output shaft, and the left end of the motor II is in spline connection with the right end of the back planetary row.

Description

technical field [0001] The invention relates to a power system of a hybrid electric vehicle, more precisely, the invention relates to a planetary dual-mode oil-electric hybrid hybrid system. Background technique [0002] Facing the current situation of energy shortage and increasingly serious environmental pollution, energy saving and environmental protection have become the only way for the development of automobiles. Hybrid electric vehicle is currently the most effective energy-saving vehicle solution, and its drive system has three forms: series connection, parallel connection and hybrid connection. Series connection can realize the optimal control of the engine, but all the energy will be converted twice, and the loss is relatively large; parallel connection can achieve better transmission efficiency, but the mechanical connection between the engine and the output shaft cannot ensure that the engine is always in a better working area ; and the hybrid can combine the ad...
