Problems solved by technology

However, this utility model cannot achieve the technical effect of self-adaptive pre-adjustment, and at the same time, it does not optimize and simplify the existing gear switching process, and there are still technical problems such as long shift time, large shift impact, and power interruption. Therefore, it is urgent to improve

Abstract

The invention relates to a double-motor self-adaptive speed pre-regulating multi-gear power coupling device and a control method thereof. The double-motor self-adaptive speed pre-regulating multi-gearpower coupling device comprises a main driving motor (8), a planetary line speed change device (100), an auxiliary motor (15), a vehicle transmission shaft (9) and a vehicle driving axle (10); the planetary line speed change device (100) comprises a planet gear mechanism and a double-way combining device (105); the planet gear mechanism comprises a planetary line sun gear (102), a planetary linegear ring (103), a planetary line planet carrier (108) and a planetary line shell (107); and the planetary line gear ring (103) is jointed with the planetary line shell (107) or a planet carrier output shaft (106) through the double-way combining device (105). Compared with the prior art, the double-motor self-adaptive speed pre-regulating multi-gear power coupling device has the advantages that running requirements of a pure electric bus can be satisfied, the rotation speed of the motor can be pre-regulated before the gear shifting process, self-adaptive speed regulation is realized to a certain degree, and the rotation speed relation is automatically regulated and matched according to gear shifting needs in any running state.

Description

technical field [0001] The invention relates to a power coupling device and a control method of a pure electric vehicle, in particular to a dual-motor adaptive pre-adjustment multi-speed power coupling device and a control method thereof. Background technique [0002] In order to cope with the worsening environmental pollution and energy crisis, it is of great significance to develop and promote pure electric vehicles. At present, pure electric vehicles have been widely used in the field of public transportation, and have shown huge advantages in energy saving and environmental protection. In order to further meet the needs of various cycle working conditions and multi-terrain use, it has become a trend to equip pure electric vehicles with transmission devices or multi-speed power coupling devices to further improve the power and economy of the vehicle. [0003] At present, people have tried to install an automatic mechanical transmission AMT on a pure electric bus. Some c...
