Embodiment Construction

[0037] The present invention is described in detail below in conjunction with accompanying drawing:

[0038] The purpose of the present invention is to provide a novel planetary dual-mode oil-electric hybrid system, that is, to provide an oil-electric hybrid system with a double planetary row as an electromechanical coupling device, so as to realize a hybrid system The electronic continuously variable transmission function of the system controls the engine to work in the best fuel economy zone, improves the fuel economy of the vehicle, and achieves ultra-low emissions. In addition, due to the addition of the clutch, the planetary dual-mode oil-electric hybrid system of the present invention can switch between the two modes to meet the different power requirements of the vehicle to obtain a higher comprehensive transmission efficiency and fuel economy.

[0039] refer to figure 1 and Image 6 , the novel planetary dual-mode oil-electric hybrid system described in the present ...

Abstract

The invention discloses a planetary type dual-mode petrol-electric parallel and serial hybrid power system. The problem that a parallel and serial hybrid power system requires a large motor is solved. The planetary type dual-mode petrol-electric parallel and serial hybrid power system comprises an engine, a first motor, a dual-clutch, a second motor, an output shaft, a front planet raw and a rear planet raw, wherein the front planet raw sleeves the right end of an output shaft of the engine; a right end of a gear ring of the front planet row sleeves the left end of the output shaft; the dual-clutch sleeves the right end of the output shaft; the left end of a left pressure plate of the dual-clutch is connected with the right end of the gear ring of the front planet row via a spline pair; the second motor is arranged on the output shaft on the right side of the dual-clutch; the rear planet row is arranged on the output shaft on the right side of the second motor; the right end of a shaft sleeve of the dual-clutch is connected with the left end of the second motor via a spline pair; the right end of the second motor is connected with the left end of a sun gear of the rear planet row via a spline pair; the first motor sleeves the output shaft, which is arranged on the left side of the front planet row, of the engine; and the right end of the first motor is connected with the left end of a sun gear in the front planet row via a spline pair.

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] With the urgency of energy issues and the continuous improvement of environmental protection requirements, energy saving and environmental protection have become inevitable requirements for future automobile development. 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 connect...
