  • Patent number: 12234901
    Abstract: Disclosed is a power distribution device, including: a case rotatably provided; a first side gear connected to a first wheel; a second side gear connected to a second wheel; a pinion gear meshed with the first side gear and the second side gear; a cage provided to support the pinion gear and to be capable of relative rotation with respect to the case; a first lock plate contacting and spaced apart from the first side gear such that the first side gear is synchronized and unsynchronized with the case; and a second lock plate contacting and spaced apart from the cage such that the cage is synchronized and unsynchronized with the case. Accordingly, it is possible to improve a size, mountability, weight and cost, and to suppress unintentional release of the lock differential, as the disconnecting function and lock differential function are implemented.
