Problems solved by technology

[0003] The current new energy vehicles are divided into pure electric and hybrid. However, their disadvantages are that their structures all adopt motor direct drive mode and dry clutch, and there is no deceleration device, which leads to a large motor size, which leads to the layout of the whole vehicle being affected. Many limitations have brought difficulty to the assembly of the vehicle factory; at the same time, due to the high torque required for driving new energy buses, the dry clutch generates a large amount of heat, is easy to wear, and has low reliability

Abstract

The invention discloses a dual-motor parallel serial driving module. A main driving motor is connected with a first input shaft; the first input shaft is connected with an output shaft through a speed reducing gear pair and is used for supplying first output power to the output shaft; a second input shaft is parallel to the first input shaft and is connected with the output shaft through a gear pair; two integrated clutches are connected with the second input shaft; and an ISG motor and an engine are connected with the clutches so as to supply second power output to the output shaft. The invention also relates to a vehicle with the dual-motor parallel serial driving module. According to the technical scheme, a convenience is brought to the arrangement of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power systems, in particular to a dual-motor hybrid drive module, and also to a vehicle with the drive module. Background technique [0002] With the continuous advancement of new energy vehicle technology, new energy vehicles are gradually favored by the market due to their environmental protection advantages. [0003] The current new energy vehicles are divided into pure electric and hybrid. However, their disadvantages are that their structures all adopt motor direct drive mode and dry clutch, and there is no deceleration device, which leads to a large motor size, which leads to the layout of the whole vehicle being affected. Many limitations have brought difficulty to the assembly of the vehicle factory; at the same time, due to the high torque required for driving new energy buses, the dry clutch generates a lot of heat, is easy to wear, and has low reliability. Contents of the inv...
