Description

Technical Field

[0001] The utility model relates to a driving motor power boosting device, in particular to a new energy driving motor power boosting device, belonging to the technical field of new energy vehicles. Background Art

[0002] New energy vehicles are an important solution to addressing the global energy crisis and environmental problems. With the continuous development of battery technology, the cruising range of new energy vehicles has gradually increased, but the power performance also faces challenges. In scenarios such as frequent starting and stopping, high-speed overtaking, and climbing in congested urban roads, the drive motor needs to be able to quickly provide appropriate power. Traditional single-speed or two-speed transmissions are difficult to meet the efficient power output requirements of new energy drive motors under all working conditions. This has prompted the search for new power enhancement solutions. Planetary gear sets came into being. They can distribute the input power to the output end in different proportions. In the new energy drive motor system, by reasonably adjusting the transmission ratio of the planetary gear set, the output torque and speed can be changed without increasing the motor power to achieve power enhancement. When large torque output is required, such as vehicle starting or climbing, the planetary gear set can convert the motor speed into a larger torque and transmit it to the wheels.

[0003] Although the planetary gear set of the new energy drive motor in the existing technology allows power transmission between multiple components and can achieve different transmission ratios, the internal space of the ring gear in the planetary gear set is limited, and more planetary gears cannot be arranged. The power transmission is limited and greater power transmission cannot be provided. For this reason, we provide a new energy drive motor power boosting device to solve the above problems.
