Embodiment Construction

[0056] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] In the prior art, the electric drive gearbox needs to cut off the power of the drive motor first during the shifting process, and then connect the output shaft of the drive motor to the gear train of the gearbox after the shifting mechanism completes the shifting action. In this way, the power is interrupted when shifting gears, which will seriously affect the driving comfort and safety of the vehicle.

Abstract

The invention relates to the technical field of electric drive gearboxes, in particular to a double-motor electric drive gearbox and a vehicle. The invention provides a double-motor electrically-driven gearbox. The double-motor electrically-driven gearbox comprises a first middle rotating shaft, a second middle rotating shaft, an output shaft, a first middle shaft tooth mechanism, a second middle shaft tooth mechanism, a first gear shifting mechanism, a second gear shifting mechanism and a third gear shifting mechanism. According to the double-motor electric drive gearbox and the vehicle, the problem of power interruption during gear shifting can be solved.

Description

technical field [0001] The invention relates to the technical field of electric drive gearboxes, in particular to a dual-motor electric drive gearbox and a vehicle. Background technique [0002] The electric drive gearbox is a gearbox used in electric vehicles. The electric drive gearbox includes a motor and a gear transmission system. The motor outputs the power from the output shaft through the gear transmission system. In the prior art, an electric drive gearbox applied to a heavy vehicle is usually driven by a single motor, and the single motor is coaxially arranged with the output shaft. [0003] In the electric drive gearbox in the prior art, the drive motor must be unloaded during the shifting process, and the power is interrupted during shifting, which will seriously affect the driving comfort and safety of the vehicle. [0004] Therefore, how to solve the problem of power interruption in the electric drive gearbox in the prior art during gear shifting has become an...
