Hybrid speed changer, hybrid driving system and hybrid car

Abstract

The invention relates to a hybrid speed changer, a hybrid driving system and a hybrid car. The hybrid speed changer comprises a first input shaft, a second input shaft and an output shaft. The first input shaft and the second input shaft are coaxially arranged. The hybrid speed changer further comprises a first gear, a second gear, a first synchronizer, a third gear, a fourth gear and a second synchronizer, wherein the first gear and the second gear are arranged on the first input shaft and are arranged adjacently in the axial direction and rotate synchronously; the second gear is arranged atone axial end of the first input shaft; the first synchronizer is arranged on the second input shaft and located at one axial side of the second gear and can be engaged with the second gear; the thirdgear, the fourth gear and the second synchronizer are arranged on the output shaft; the third gear and the fourth gear are arranged on the output shaft in an idle sleeving mode; the second synchronizer is located between the third gear and the fourth gear and can be engaged with the third gear or the fourth gear; the third gear and the fourth gear are engaged with the first gear and the second gear correspondingly.

Description

technical field [0001] The invention relates to the field of hybrid vehicles. In particular, the present invention relates to a hybrid transmission and a hybrid driveline and a hybrid vehicle including the hybrid transmission. Background technique [0002] A hybrid vehicle is a vehicle that uses more than two sources of power. The most common gasoline-electric hybrid vehicles use a traditional internal combustion engine (diesel or gasoline) and an electric motor as power sources. [0003] From the prior art, various arrangements of hybrid drive trains in hybrid vehicles are known. A commonly used add-on arrangement is to additionally add a hybrid module between the internal combustion engine and the transmission of the traditional internal combustion engine drive system, wherein the hybrid module includes a clutch for coupling or cutting off the power transmission between the internal combustion engine and the electric motor, the electric motor , a casing for the hybrid p...
