The invention relates to a transmission assembly for a hybrid electric vehicle. According to the transmission assembly, the requirement for the performance of a drive motor can be lowered. A first permanent magnet motor output shaft is connected with a first permanent magnet motor and provided with a first permanent magnet motor output shaft gear. An input shaft is provided with an input shaft gear engaged with the first permanent magnet motor output shaft gear. A first clutch, a needle bearing and a second intermediate shaft gear are assembled on an intermediate shaft. The needle bearing is sleeved with a first intermediate shaft gear in a spaced manner. The first intermediate shaft gear is connected with a first clutch gear hub and engaged with the input shaft gear. A main speed reduction gear is connected with a differential mechanism assembly. A sun gear of a planet gear disc assembly is an axial gear integrated with a second permanent magnet motor output shaft. A planet gear is supported on a planet carrier and engaged with the sun gear and a gear ring. A normally-engaged gear and the planet carrier are assembly on the second permanent magnet motor output shaft in an integrally-connected manner and engaged with the main speed reduction gear. A second clutch is arranged between the planet carrier and the gear ring. A second intermediate shaft gear is engaged with the main speed reduction gear.
Description
technical field [0001] The invention relates to an automobile transmission, in particular to a hybrid electric automobile transmission assembly. Background technique [0002] Due to the aggravation of energy crisis and environmental pollution, governments and automobile companies of various countries have made energy saving and emission reduction the main plan for future automobile development. Therefore, as a kind of new energy vehicles, hybrid vehicles have also received extensive attention, and the transmission assembly as a core component is even more critical. Most of the existing hybrid vehicle transmissions use a single-speed reduction mechanism when driving purely on electricity, and even a small number of two-speed transmission mechanisms are parallel shaft gear mechanisms. The single-speed reduction mechanism is usually two pairs of constant mesh gear pairs with gears fixed on the input shaft, intermediate shaft and output shaft respectively. It is a fixed transmi...
