Abstract

The invention provides a double dynamic coupling driving structure which utilizes a dual-motor multi-mode coupling driving mode. A double planet rank system which consists of a first planetary gear mechanism (8) and a second planetary gear mechanism (4) is served as a dynamic coupling device for a first motor (15) and a second motor (12). The first motor (15) and the second motor (12) are arranged on the same side and are arranged in an axial parallel mode. A locking device (5) is used for locking and unlocking a planet carrier gear ring (23). A second clutch (10) is used for connecting and disconnecting power transmission between a second decelerator (11) and a power input gear (9). A first clutch (17) is used for connecting and disconnecting the power transmission between a first decelerator (16) and a sun wheel set shaft (9). The dual-motor multi-mode coupling driving structure can achieve multiple operating modes, wherein the multiple operating modes comprise a two motor individual driving mode, a dual-motor rotating speed coupling driving mode and a dual-motor rotating torque coupling driving mode, and different travel requirements of vehicles can be met.

Description

technical field [0001] The invention belongs to the technical field of power assembly components, and in particular relates to a dual-motor power coupling drive assembly. Background technique [0002] At present, the electric drive device of electric buses often uses a single high-power drive motor and gearbox. By controlling the gearbox to work in different gear ratios, the torque and speed output by the drive system are adjusted to meet the requirements of vehicle climbing and high-speed driving. . With the continuous improvement of the driving comfort requirements of vehicles, the use of automatic transmissions in gearboxes has become an inevitable trend. However, during the shifting process of the automatic transmission, due to the need to cut off the power source, power interruption occurs when the vehicle shifts gears, thus causing problems such as vehicle stall and impact. [0003] The Chinese patent application number 201010100671.7 discloses a double-motor speed c...
