Abstract

The present invention relates to an automobile drive device and an automobile, comprising a power generation drive module, an engine, a speed-increasing gear, a motor drive module and a reduction gear; the power generation drive module includes at least one generator motor, and one end of each generator motor is connected with a first transmission gear , the other end of each generator motor is connected with a second transmission gear, and the second transmission gear meshes with the reduction gear; the engine meshes with the first transmission gear through the speed-up gear, and a first clutch is arranged between the engine and the speed-up gear to generate electricity A second clutch is arranged between the motor and the second transmission gear; the motor drive module includes at least one drive motor, each drive motor is connected with a third transmission gear, the third transmission gear meshes with the reduction gear, and the reduction gear is connected with the vehicle wheel. The present invention controls the working state of each motor through the combined arrangement of a plurality of motors, and can avoid the influence of a single motor failure while satisfying the drive, improve the cruising range of the whole vehicle, and reduce the influence of power interruption.

Description

technical field [0001] The invention relates to the technical field of automobile driving, in particular to an automobile driving device and an automobile. Background technique [0002] As the energy crisis and environmental pollution problems continue to intensify, countries around the world, especially China, which is a major automobile country, are vigorously advocating and paying attention to the development of electric vehicles, and their electric drive systems have become the focus of research and development by various companies. However, in the field of large-tonnage and long-range vehicle applications, the vehicle requires a large output torque, a high maximum speed, and a long cruising range. [0003] For the existing pure electric heavy-duty truck scheme, a single high-torque, low-speed drive motor is mostly used, combined with a multi-speed EMT transmission device and a large-power battery scheme. The development of EMT system shift control for this scheme is rel...
