Abstract

The invention discloses a dual mechanical port driving device for an electric automobile. The dual mechanical port driving device comprises a first driving mechanism, a second driving mechanism, a cage rotor, a first transmission mechanism and a second transmission mechanism, wherein the first driving mechanism and the second driving mechanism are coaxially arranged in parallel. The first driving mechanism and the second driving mechanism each comprise a stator and a wound rotor, wherein the stator is fixedly arranged and wound with a stator winding; and the wound rotor is rotatably arranged in the stator and can perform rotary motion to be output through a first shaft. The cage rotor is arranged between the stator and the wound rotor and performs rotary motion to be output through a second shaft. The first transmission mechanism and the second transmission mechanism are connected with the first driving mechanism and the second driving mechanism respectively, selectively output power of the first shaft or the second shaft, and can selectively fix the first shaft. According to the dual mechanical port driving device, multiple working modes can be achieved, the first driving mechanism and the second driving mechanism can be locked together, and the dual mechanical port driving device has the advantage of being high in reliability.

Description

technical field

[0001] The invention relates to the technical field of electric vehicle drive mechanisms, in particular to a dual mechanical port drive device for electric vehicles. Background technique

[0002] With the continuous growth of car ownership in various countries in the world, the global oil extraction has increased rapidly. However, oil resources on the earth are limited, and excessive exploitation will inevitably lead to an energy crisis. Therefore, it is imperative to increase the research and development of new energy vehicles. As a main type of new energy vehicles, pure electric vehicles are all driven by electricity. Compared with traditional fuel vehicles, electric vehicles require a wide range of sources of electric energy and can achieve zero emissions during operation, which plays a role in protecting the environment. Function; braking energy can be recovered during braking, saving a lot of electric energy. As the core component of the drive system,...
