Huawei patents new reducer and powertrain technologies for electric vehicles



On September 24, 2020, Huawei applied for a new patent named Reducer, powertrain, and vehicle, which is publically published on January 22, 2021, with publication number CN112248801A in China.

The patent describes that the reducer can be applied to electric vehicles, pure electric vehicles, hybrid vehicles, extended-range electric vehicles, plug-in hybrid vehicles, new energy vehicles, etc.

The reducer realizes shifting without power shock by canceling the setting of the synchronization ring and controlling the rotation angle and speed. Shortening of the shifting stroke and synchronization time can help in saving costs and solving the problem of adopting. The friction of the synchronizing ring achieves the synchronous shifting, which causes the problem of long shifting time and impact during shifting.

Following this new patent, it seems that Huawei focusing on ICT technology to help car manufacturers to build new cars using technology. And planning to become a large component provider for intelligent car manufacturers.


Most of Deng Li's smartphones are from the Huawei ecosystem and his first Huawei phone was Ascend Mate 2 (4G). As a tech enthusiast, he keeps exploring new technologies and inspects them closely. Apart from the technology world, he takes care of his garden.
