Title:
DIFFERENTIAL DEVICE AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/044904
Kind Code:
A1
Abstract:
Provided are a differential device and an electric device. The differential device comprises a power mechanism (10) and a plurality of transmission assemblies. The power mechanism (10) comprises a first transmission member (1); the plurality of transmission assemblies each comprise a second transmission member (2) and a power output member (3) connected to the second transmission member (2); and the first transmission member (1) is connected to the second transmission members (2) of the plurality of transmission assemblies. By providing the first transmission member (1) and the plurality of transmission assemblies, the power mechanism (10) can be stably connected to the plurality of transmission assemblies, so that the ratio of an input speed on the power mechanism (10) to an output speed on the power output members (3) is maintained at a relatively high level, thereby achieving large-speed-ratio transmission; and then, at least some parts in the differential device, such as the first transmission member (1) and the plurality of transmission assemblies, can be provided outside the power mechanism (10), thereby reducing the effect of insufficient space on the structures of the first transmission member (1) and the plurality of transmission assemblies, and improving the bearing capability of the differential device.
