Embodiment Construction

[0039] The present invention is described in detail below in conjunction with accompanying drawing:

[0040] 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 Shortcomings.

[0041] refer to figure 1 and Figure 4 , the dual-planetary oil-electric hybrid system of the present invention is mainly composed of engine 1, No. 1 inverter 4, supercapacitor 5, No. 2 inverter 6, No. 2 motor 7, and No. 1 motor 12 , the front plane...

Abstract

The invention discloses a double-planet row type oil and electricity series-parallel type hybrid power system. The double-planet row type oil and electricity series-parallel type hybrid power system aims at solving the problem that a big motor is needed to supply enough driving force in an existing series-parallel hybrid power vehicle. The double-planet row type oil and electricity series-parallel type hybrid power system comprises an engine, a front planet row, a back planet row, a first inverter, a super-capacitor, a second inverter, a second motor, a first motor and a front planet row output shaft. The front planet row is arranged at the left end of the front planet row output shaft in a sleeved mode, the first motor is arranged at the right end of the front planet row output shaft in a sleeved mode, the left end of the first motor is connected with a front planet row sun wheel button, the right end of the engine is connected with a front planet row gear ring cover in a keyed mode, the input end of the second motor is connected with the right end of the front planet row output shaft in a keyed mode, and the output end of the second motor is connected with a back planet row sun wheel in a keyed mode. The first motor is connected with the first inverter in a wire mode, the second motor is connected with the second inverter in a wire mode, the first inverter is connected with the super-capacitor in a wire mode, the second inverter is connected with the super-capacitor in a wire mode, and the first inverter is connected with the second inverter in a wire mode.

Description

technical field [0001] The invention relates to a power system of a hybrid electric vehicle, more precisely, the invention relates to a dual-planetary 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 ; Hybrid connection can combine the adva...
